Cloud computing isn’t anything new to the business. Nearly 98% of businesses have their hardware servers on-premises to manage their IT infrastructure. However, the pandemic has caused some changes. Today, companies consider cloud migration and staying away from older systems to ensure that their business is uninterrupted. A survey from Flexera revealed that more than half of organizations believe, cloud migration can help to improve business sales and productivity.

The cloud migration process can be overwhelming. There are concerns about stability costs, stability, and security issues. For many, the successful migration of cloud services reduces cost, enhances scalability and drastically reduces the likelihood of cyber-attacks which could cripple your business. Let’s get started to find out what cloud migration is? How difficult is it to complete? What are the advantages of cloud migration?

What is Cloud Migration?

It is the procedure of moving digital business processes to the cloud. Cloud migration can be described as similar to a physical move. It involves moving information, applications or IT systems from certain data centers to different data centers. Like moving from one office to a larger one, cloud migration takes some planning. However it is typically worthwhile, as it results in lower costs and more flexibility.

In simple terms, cloud migration is defined as the process of migrating on-premises infrastructure to the cloud. Instead, the term could describe a migration from one cloud and another.

Cloud Service Models

There are 3 major cloud service models designed to meet the specific requirements of business. Also to create a cloud-based environment as appropriate as it can be.

• Software as a service (SaaS): Software accessible through vendors on the internet. Salesforce, Dropbox, Slack and MailChimp are just a few examples of SaaS.
• Platform as a service (PaaS): Platforms that provide the tools required to develop applications. A few examples are AWS Elastic Beanstalk, Heroku and other Microsoft Azure services.
• Infrastructure as a service (IaaS): Cloud-based platforms that use a pay-as-you-go method to offer computing facilities. For example, AWS EC2, Rackspace, Digital Ocean and Google Compute Engine are some examples of IaaS.
• On-Premises: Hardware and software installed at the company’s office or datacenter.

Cloud Deployment Models

In simple words, cloud deployment is how software is made accessible. This, in turn, impacts who has access to the cloud’s data and how.

There are three major models:

Public Cloud: This cloud computing model makes digital assets in the cloud accessible to the public via the internet. Google, Facebook and LinkedIn are all examples of publicly available services. These cloud services are usually available for free to customers or on monthly-fee basis (i.e., PaaS, SaaS).
Private Cloud: This type of cloud serves to one specific organization and cannot be accessed by any outsider or third-part.
Hybrid Cloud: It is possible to discern by the name it is a mix of infrastructure on-premises with cloud computing, including public cloud and private cloud. Large corporations typically use it to store important data in the private cloud and various support-related services in the public cloud.

What are Common Cloud Migration Challenges?

The process of moving cloud resources can be complicated and dangerous. Here are a few most significant challenges many companies face when they migrate their resources to cloud computing.

Lack of Strategy

Many businesses begin their journey to cloud computing without giving enough time and effort to their cloud strategy. The successful adoption of cloud technology and implementation requires a thorough plan of action from beginning to end. Every dataset and application might have its demands and requirements that require a different approach for cloud migration. The company must develop a clearly defined reason for every one of the workloads it transfers into the cloud.

Cost Management

During migration, many organizations haven’t established clear KPIs to better understand how much they will invest or save upon transition. This makes it hard to determine if the migration was successful from a financial perspective. Cloud environments are ever-changing, and costs change quickly as new services are embraced and the use of applications increases.

Vendor Lock-In

Lock-in by vendors is a typical issue for adopting cloud technology. Cloud providers provide a wide array of services, but they are not all expanded to different cloud providers. Transferring the workload from one provider to the next is a long and expensive process. Many companies begin using cloud services and then find it difficult to change providers, if the service they’re using currently doesn’t meet their business requirements.

Data Security and Compliance

One of the main challenges to cloud migration is protection and conformity. Cloud solutions employ the model of shared responsibility. They assume responsibility for the security of their infrastructure, and the user is accountable for protecting their data and their workloads. While the cloud service can provide security features, it is your company’s responsibility to ensure that they are properly configured. Ensure that all applications and services come with the proper security safeguards. The process of migration itself can pose a security risk. Sometimes moving large amounts of data that may be sensitive. Also setting access controls for programs across multiple environments, exposes users to substantial risk.

What Cloud Migration Strategy Should Enterprises Adopt ?

Gartner, an important research and development company in information technology, offers five options for companies looking to move to cloud computing. Cloud strategies for migration are generally referred to by “5 R’s”.

Rehost: Rehosting, or ‘lift and shift,’ involves using infrastructure-as-a-service (IaaS), you can redeploy existing applications and data on your cloud servers. It’s simple and suitable for companies that aren’t accustomed to cloud-based systems. It’s also an excellent alternative for situations when it’s difficult to alter the code, and you need to move your application without compromising it.

Refactor: Companies going with refactoring the pre-existing codes and frameworks. However, their applications still run on the PaaS provider’s platform, unlike rehosting.

Revise: This strategy involves rewriting or expanding the code base before applying it through Rehosting or restructuring (see earlier).

Rebuild: “Rebuild” involves rewriting and restructuring the application from scratch on the PaaS vendor’s platform. It can be a time-demanding process, but it also lets developers use the latest features offered by PaaS providers.

Replace: Businesses also have the option to discard their existing or old applications and switch to a pre-built SaaS application from a third-party service provider.

The Cloud Migration process in 4 Steps

Cloud Migration Planning

Before moving data to cloud storage, the first thing to take is to identify what purpose the Cloud’s public service will be used for. Could it be used to help in disaster recovery, Hosting business workloads completely moving to cloud computing Or, will a hybrid approach be the best option for your application.

At this point, it’s essential to analyze your surroundings and identify the elements that will influence the migration process, such as important application data, old data, and interoperability between applications. It is also essential to assess your dependence on data. Do you have data that must be synced frequently or data compliance requirements to be met or other data that could be moved in the initial few phases of the process

Knowing these needs will allow you to create a plan of action to use the tools you’ll require to migrate, including identifying what data must be transferred and when. Also, should the data require some scrubbing, what type of volume to be used for the destination, as well as whether you’ll require encryption of your data at rest and while in transit.

Business Case Migration

After you have identified your company’s requirements, be aware of the services provided by cloud service providers and other partners and the costs associated with them. Consider the anticipated benefits of cloud migration in three areas: operational benefits, cost savings, and improvements to the architecture.

Make a business plan for every application you want to move to the cloud. It should include the expected total cost of operation (TCO) for cloud services compared to the current TCO. Use cloud cost calculators to calculate costs using realistic assumptions, such as the quantity and type of storage, computing resources, and operating systems, types, and particular requirements for networking and performance.

Engage in conjunction with cloud services providers to understand the cost-saving options available for your cloud deployment. Cloud providers offer various pricing models and huge discounts as a condition of an ongoing engagement to cloud services (reserved plan) or commitment to a specific amount of cloud usage (savings plan). Discounts must be included in your company’s business plan to determine the actual costs of the cloud migration over time.

Cloud Data Migration Execution

After your environment is evaluated and a strategy has been drawn up, then it’s time to begin your move. The biggest challenge is to complete your move with the least interruption to your normal operations, at the least cost and in the least amount of time.

If your data is not accessible to users after an upgrade, you risk negatively impacting your business. This is the same case if you continue to update and sync your systems after completing the initial transfer. Each element of your workload must be tested to ensure it works in the new environment before moving to another component.

Additionally, you’ll need to discover a method to sync changes made to the original data source while the migration process is on. AWS and Azure offer built-in tools that assist in AWS cloud migration.

Ongoing Maintenance

Once the data is transferred to the cloud, it’s crucial to ensure that it is properly optimized and secure and accessible in the future. It is also useful to keep track of any real-time changes to the important infrastructure and anticipate the likelihood of workload conflicts.

With real-time monitoring, you should also evaluate the security of your data in transit to ensure that your work within your new setting complies with the requirements of compliance with regulations like HIPAA and GDPR.

Another thing to consider is to meet the regular benchmarks for availability and performance to ensure that you meet your Recovery Point Objective (RPO) and Recovery Time Objective (RTO) goals are not affected should they change.

Benefits of Migrating your Application to the Cloud

If you’re aware of the available options and what you can do, it’s time to figure out how to gain by cloud migration.

Allow Digital Transformation

Many companies are going through a digital transformation to get incremental value from existing assets. With the recent innovations in cloud computing, executives can digitize more of their core functions such as SAP, CRM the data analysis, and many more.

Anyone who migrates from outdated technologies could improve the productivity of their workforces, develop new ideas and discover new revenue sources compared to their competitors. Once in the cloud, there are limitless possibilities.

Scalability

With cloud-based workloads, it is possible to respond quickly to the demands of peak times and decrease capacity when necessary. This is all done automatically and does not require much time or effort. If you use on-premises hosting, you’ll require additional equipment and set it up to expand capacity. However, once a load peak is over, you’ll need to cover the cost of redundant resources it uses.

Yedpay is a payment service that has decided to move to the cloud following problems with their data centres. There was no need for large IT investment and personnel to maintain physical infrastructure. The company was able to cut expenses by 40%.

Enables Remote Working

In addition to reducing the carbon footprint, cloud-based companies enable their workers to connect to work from any place. When COVID-19 was first introduced, Cloud-powered businesses were the best at adapting to the government’s mandated homeworking. Since it has now been established as a viable working method and a viable option for employees, they are likely to seek the flexibility of their managers more than they have ever. Making the switch to the cloud could be essential in keeping and attracting top employees.

Reliability

There are examples where cloud deployments are smooth. There may be issues with the hardware or downtime. But cloud migration can effectively decrease downtimes and reduce the risk of data loss shortly.

Cloud providers typically offer service-level agreements which guarantee 99% uptime. In addition, they are responsible for disaster recovery and backups which can help save time for your staff.

The Under Armour Connected Fitness platform was faced with a reliability issue. The company was operating two data centres and, when problems occurred in the first one, it would result in outages. The company then shifted to cloud computing, which solved the problem.

Time-Saving

Not only is it simpler than ever before to move your existing systems to the Cloud computing system, but doing this will reduce time and effort in installing new applications or training to your company.

With no data centres to frequently restore, backup, and back up, your IT teams have more time to focus on the day-to-day running of your company. In addition, Cloud-based tools for collaboration enable collaboration and communication much easier than ever. This means more times used by more people, making you more productive.

Rapid Implementation

From a growth perspective for business, cloud computing provides endless opportunities for companies. Also, it is a source of the speed of digital advancement. With the flexibility of technology offered by cloud-based providers developers, you can streamline and speed up processes.

Capital One back of the US managed to reduce the mobile app development build time. They did it by moving their services to cloud.

Capital One, one of the biggest U.S. banks, managed to cut down the mobile app development environment’s build time from months to just a few minutes following its move to the cloud.

Availability

Cloud computing allows you and your staff to access your applications from any part of the globe at any point. It allows companies to offer employees a flexible work schedule and a seamless transition to remote working.

The Key Takeaway

One thing is certain that almost every business driven by technology must have at least a Cloud migration plan. If you don’t, then why wouldn’t you? The need to migrate from outdated software is the right step to take. It is a must-have to ensure continuity of business and an investment that will pay promptly for many firms.

The Elastic Stack, or ELK stack, is a collection of open-source software tools for log and data analytics. In many different IT environments, including cloud environments like AWS (Amazon Web Services), it is typically used for centralized logging, monitoring, and data analysis.

Three main parts to the ELK stack

1. Elasticsearch: Designed for horizontal scalability, Elasticsearch is a distributed, RESTful search and analytics engine. Data is stored and indexed, making it searchable and allowing for real-time analytics. In the ELK stack, Elasticsearch is frequently used as the primary data storage and search engine.
2. Logstash: This data processing pipeline uses logs, metrics, and other data formats to ingest, transform, and enrich data from a variety of sources. Before sending data to Elasticsearch for indexing and analysis, it can parse and structure it. In order to facilitate integration with various data sources and formats, Logstash also supports plugins.

3. Kibana: A user-friendly interface for querying and analyzing data stored in Elasticsearch is offered by the web-based visualization and exploration tool known as Kibana. For the purpose of displaying log data and other types of structured or unstructured data, users can create dashboards, charts, and graphs.

You can deploy these components on AWS infrastructure when using the ELK stack on AWS, taking advantage of AWS services like Amazon EC2 instances and Amazon Elasticsearch Service, and Amazon Managed Streaming for Apache Kafka

How the ELK stack can be installed on AWS

1. Elasticsearch: Using Amazon Elasticsearch Service, you can set up and manage Elasticsearch clusters on AWS, which streamlines the deployment and scaling of Elasticsearch. The provisioning, maintenance, and monitoring of clusters are handled by this service.

2. Logstash: AWS Fargate or Amazon EC2 containers can be used to deploy Logstash. You set up Logstash to gather data from various sources, parse it, and then transform it before sending it to Elasticsearch.

3. Kibana: Kibana connects to the Elasticsearch cluster and can be installed on an EC2 instance or used as a service. It offers the user interface for data exploration, analysis, and visualization.

By utilizing AWS infrastructure and services, you can guarantee scalability, reliability, and ease of management when deploying the ELK stack for log and data analytics in your AWS environment.

More about Elastic Search

Although Elasticsearch is not an AWS (Amazon Web Services) native service, it can be installed and managed on AWS infrastructure using AWS services. Full-text search and log data analysis are two common uses for the open-source.

Elasticsearch functions as follows, and using it with AWS is possible:

1. Data Ingestion: Elasticsearch ingests data from various sources in almost real-time. This information may be text, both structured and unstructured, numbers, and more. To stream data into Elasticsearch, use AWS services like Amazon Kinesis, Amazon CloudWatch Logs, or AWS Lambda.

2. Indexing: Elasticsearch uses indexes to organize data. A collection of documents that each represent a single data record makes up an index. Elasticsearch indexes and stores documents automatically, enabling search.

3. Search and Query: Elasticsearch offers robust query DSL (Domain Specific Language) search capabilities. On the indexed data, users can filtering, aggregations, and full-text searches. Inverted indices are used by the search engine to expedite searches, making it possible to retrieve pertinent documents quickly and effectively.

4. Distributed Architecture: Elasticsearch is made to be highly available and scalable. It can manage huge datasets and distribute data across many nodes. AWS provides services like Amazon EC2, Amazon Elasticsearch Service, and Amazon OpenSearch Service, that can be used to deploy Elasticsearch clusters.

5. Replication and Sharding: To ensure data redundancy and distribution, Elasticsearch employs replication and sharding. Each of the smaller units of data, or “shards,” may contain more than one replica. This guarantees parallel search operations as well as fault tolerance.

6. Text analysis and tokenization are carried out by Elasticsearch during indexing. For easier searching and filtering of text-based data, it uses analyzers and tokenizers to break down text into individual terms.

7. RESTful API: Developers can communicate with Elasticsearch through HTTP requests thanks to its RESTful API. As a result, integrating Elasticsearch with different programs and services is made simple.

8. Visualization: Kibana, a tool for data exploration and visualization, is frequently used in conjunction with Elasticsearch. Users can build dashboards, charts, and graphs using Elasticsearch data with Kibana, which offers insights into the indexed data.

Although Elasticsearch is not an AWS service, you can use AWS infrastructure to deploy it using services like Amazon EC2, manage it yourself, or use Amazon OpenSearch Service, which is a managed alternative to Elasticsearch offered by AWS.

Elasticsearch is an effective indexing, searching, and analytics tool for data. In order to take advantage of Elasticsearch’s scalability, dependability, and usability, AWS offers a variety of services and resources that can be used to deploy and manage clusters on its infrastructure.

Elastic Search and Kibana

In order to create scalable and potent analytics solutions, Elasticsearch and Kibana, two components frequently used in conjunction for log and data analysis, can be deployed on AWS (Amazon Web Services).

Kibana

An open-source tool for data exploration and visualization called Kibana integrates perfectly with Elasticsearch. It offers users a web-based interface through which they can interact with and view Elasticsearch data. You can build custom dashboards with Kibana, create visualizations (such as charts, maps, and graphs), and explore your data to discover new information. Elasticsearch and Kibana are frequently combined to produce powerful data-driven dashboards and reports.

What you can do by using Kibana and Elastic Search

1. Amazon Elasticsearch Service: This is an AWS managed Elasticsearch service. Elasticsearch cluster deployment, scaling, and management are made easier. Using this service, you can easily set up and configure Elasticsearch domains.

2. EC2 on Amazon: If you need more control and environment customization, you can also decide to deploy Elasticsearch and Kibana on Amazon Elastic Compute Cloud (EC2) instances.

3. Amazon VPC: To isolate your Elasticsearch and Kibana deployments for security and network segmentation, use Virtual Private Cloud (VPC).

4. Amazon S3: Elasticsearch can be used to index and search data that is stored in Amazon S3. Your Elasticsearch cluster can use S3 as a data source.

5. IAM (AWS Identity and Access Management): Only authorized users and services are able to interact with your Elasticsearch and Kibana resources thanks to IAM management of access control.

6. Amazon CloudWatch: Your Elasticsearch and Kibana clusters’ performance can be tracked using CloudWatch, and alarms can be set up for a number of metrics.

Elasticsearch and Kibana on AWS offer a robust platform for log and data analysis, simplifying the management and scaling of your analytics infrastructure while utilizing AWS’s cloud services.

Logstash

With the help of the open-source data ingestion tool Logstash, you can gather data from various sources, modify it, and send it where you want it to go. Regardless of the data source or type, users can easily ingest data using Logstash thanks to its prebuilt filters and support for more than 200 plugins.

An easy-to-use, open-source server-side data processing pipeline called Logstash enables you to gather data from various sources, transform it as you go, and send it where you want it to go. Most frequently, Elasticsearch uses it as a data pipeline. Logstash is a well-liked option due to its tight integration with Elasticsearch, potent log processing capabilities, and more than 200 prebuilt open-source plugins that can help you easily index your data.

Kibana or Logstash

Explore & Visualize Your Data with Kibana.

For Elasticsearch, Kibana is an open source (Apache Licensed), browser-based analytics and search dashboard. Kibana is simple to set up and use. Collect, Parse, & Enrich Data are flexible and easy to use in Kibana.

A tool for managing events and logs is called Logstash. It allows you to gather logs, analyze them, and store them for later use (such as searching). You can view and examine them with Kibana if you store them in Elasticsearch.

Kibana offers a variety of features, including: A flexible analytics and visualization platform; real-time summarization and charting of streaming data; and an intuitive user interface.

SoundCloud first developed Prometheus back in 2012. Since its creation, Prometheus Monitoring Tool has grown to be a well-liked monitoring tool that is supported by a diverse group of contributors. Prometheus joined the Cloud Native Computing Foundation (CNCF) in 2016 and has since graduated from the organization.

An open-source monitoring and alerting toolkit with scalability in mind is called Prometheus. It is widely utilized in the world of containerized and cloud-native applications. Prometheus monitoring tool is often used in Kubernetes environments to monitor various aspects of applications and infrastructure, collecting metrics from targets like HTTP endpoints, databases, and other systems. It scrapes metrics from these targets using a pull-based model and stores the information in a time-series database.

Prometheus’ main characteristics

• Multidimensional data model: Allows users to analyze data in a variety of ways to learn more about the functionality and health of the system.PromQL is a strong and user-friendly query language for aggregating and querying metrics.
• Effective time-series storage: To make it simple to query and analyze historical data, all collected metrics are stored in a time-series database.
• Pull model for metric collection: Scrapes targets on a regular basis to gather metrics data, enabling it to scale horizontally to watch over big and complex systems.
  Pushing time-series data to Prometheus is supported, making it simple to monitor customized applications and services.
• Automatic target discovery for monitoring: A built-in mechanism for service discovery that automatically finds and keeps track of new services as they are added to a system.
• Built-in visualization tools: Offers a number of built-in visualization tools, including integration with Grafana and a straightforward graphing user interface.
• Strong query capabilities: Enables users to construct intricate queries that filter, aggregate, and transform data, facilitating in-depth system analysis.
  Ease of operation designed to be simple to use, with an easy installation procedure and configuration.

Integrations with numerous platforms and tools: allows for easy integration with a wide range of other tools and platforms, making it simple to monitor distributed, complex systems in a variety of settings.

Prometheus Monitoring: How Does It Operate?

Prometheus monitoring needs an exposed HTTP endpoint in order to collect metrics. Prometheus can begin scraping numerical data as soon as an endpoint is available, record it as a time series, and store it in a local database designed to store time-series data. Remote storage repositories can also be integrated with Prometheus monitoring.

To generate temporary times series from the source, users can use queries. The names and labels of the metrics used to define these series. PromQL, a special language that enables users to pick and aggregate time-series data in real time, is used to write queries. You can create alert conditions with PromQL that will send notifications to outside systems like email, PagerDuty, or Slack.

Prometheus’ web-based user interface allows for the display of collected data in tabular or graph form. Additionally, you can integrate third-party visualization programs like Grafana using APIs.

What Can Prometheus Be Used To Monitor?

You can use Prometheus, a flexible monitoring tool, to keep an eye on a range of infrastructure and application metrics. Here are a few typical use scenarios.

1.Metrics for Services

Prometheus monitoring is frequently used to gather numerical metrics from services that operate continuously and permit HTTP endpoint access to metric data. Manual labor or a variety of client libraries can accomplish this. Prometheus exposes data in a straightforward format, with a new line for each metric and line feed characters to denote separation. Based on the specified path, port, and hostname, Prometheus can query and scrape metrics from the file that is published on an HTTP server.

Additionally, distributed services that run across multiple hosts can be implemented using Prometheus. Each instance has a name that Prometheus can distinguish and publishes its own metrics.

2.Website Uptime/Up Status

Prometheus typically doesn’t keep track of the status of websites, but you can do so by using a blackbox exporter. In order to obtain information such as the website’s response time, you must perform an uptime check and specify the target URL to query an endpoint. In order to make sure Prometheus uses the blackbox exporter, you define the hosts to be queried in the prometheus.yml configuration file.

3.IoT Monitoring

Prometheus can keep an eye on IoT systems and gadgets. It can gather metrics data on things like battery life, network latency, and device temperature and notify administrators of problems.

4.Security Monitoring

It can keep track of security-related statistics like login attempts, network activity, and system logs and notify administrators of security breaches or other problems when necessary.

5.Business Metrics Monitoring

Prometheus has the ability to keep track of financial metrics like revenue, sales, and customer retention. It can help you make data-driven decisions and offer insights into the state of your company.

Host Metrics

You can check the operating system to see if a server is running at 100% CPU all the time or if its hard drive is full. Installing a specialized exporter on the host will allow you to gather the operating system details and publish them somewhere that can be accessed over HTTP.

Cronjobs

You can display metrics to Prometheus through an HTTP endpoint using the Push Gateway to determine whether a cronjob is running at the predetermined intervals. You can compare the current time in Prometheus with the timestamp of the most recent successful job (a backup job) that was pushed to the Gateway. The monitor times out and sends out an alert if the time goes over the predetermined threshold.

Why Should You Monitor Kubernetes Using Prometheus?

Due to the fact that it was created for a cloud-native environment, Prometheus is a popular option for Kubernetes monitoring. The following are a few major advantages of using Prometheus to track Kubernetes workloads:

 Multidimensional data model – The way Kubernetes organizes infrastructure metadata using labels and key-value pairs is similar. This similarity guarantees that Prometheus can gather and analyze time-series data with accuracy.

 Accessible format and protocols – Prometheus allows for quick and easy metric exposure. It makes sure that metrics can be published over a regular HTTP connection and are readable by humans.

 Service discovery – The Prometheus server scans targets on a regular basis. Metrics are pulled rather than pushed, so services and applications are not required to continuously emit data. Several methods can be used by Prometheus servers to automatically find targets for scraping. For instance, you can set up the servers to match and filter container metadata.

 Modular and highly available components – Composable services are in charge of performing metric collection, graphical visualization, alerting, and more. They are composed of modular and highly available components. Redundancy and sharding are supported by each of these services.

Metric Types in Prometheus

Prometheus’ client libraries provide four basic categories of metrics. These metrics are not currently saved by the Prometheus server as different data types. It flattens all data into an untyped time series instead.

Counter

This metric is cumulative. It stands for a single monotonically increasing counter, and on restart, it can either increase in value or reset to zero.

There are numerous use cases where counter metrics are appropriate. It can be used, for instance, to show the quantity of errors, requests, or tasks that have been fulfilled. Counters should never be used to display values that are subject to change, such as the number of active processes.

Gauge

This metric represents a single numerical value that may be arbitrarily increased or decreased. Values like current memory usage or temperatures are frequently measured using a gauge.

Histogram

A histogram compiles data from observations, such as response times or request durations. The observations are then added up in a customizable bucket. A histogram can also show the sum of all the values that were observed.
