What is AWS?

Amazon Web Services (AWS) is a cloud platform that provides scalable, flexible, reliable, and cost-effective cloud computing solutions. It is an easy-to-use cloud computing platform offered by Amazon, and AWS delivers organizations tools such as database storage, compute power, and other services. It was launched in 2002, initially built for retail operations, but later it has grown more prominent in providing over 200 services, of which migration is one of its services.

What is AWS Migration?

AWS Migration is the process of migrating the project objectives and the data from the on-premise data center to AWS. Organizations can perform migration based on many factors, such as global market expansion, the need for standard architecture, hardware upgrades, data center leases, software license renewals, or location requirements to meet regulatory compliance.

Phases of AWS Migration

AWS Migration is designed to help organizations execute the migration of a vast number of applications. The AWS Migration includes the following phases:

1. Prepare : Preparation is the first phase of the database migration, designed to identify the interdependencies between the database and the application. It analyzes the workloads and determines the migration categories from simple rehost to re-architect migration. In this phase, the organization has to involve the leadership team to communicate frequently and make excellent decisions about the migration.

2. Plan : In this phase, a complete portfolio analysis of interdependencies, migration strategies, and priorities is defined to build a successful migration plan. Based on the information collected in the above phase, the database migration strategy is defined among the 7Rs- Rehost, Replatform, Relocate, Refactor, Retire, Repurchase, and Retain. The migration strategy is determined by the organization’s migration requirements, such as financial limitations, schedule, and personal needs.

3. Migrate : In this phase, the migration process begins with defining the target database, migrating the source data to the target database, and validating the data. It is an iterative method that includes several cycles, and each process consists of the following steps:

1. Converting the schema
2. Migrating the data
3. Updating the application
4. Testing the migration
5. Cutting over to the new database

After completing the performance and functional testing, you can cut over to the new database.

4. Operate and Optimize : Once the application is migrated, you can optimize the new application by utilizing the AWS services and features within a few clicks. AWS enables us to build and deploy innovative applications within minutes. It provides the regular updates required to install the application and allows 24/7 support on tracking system maintenance and updates after migration.
