On-premise apps include all applications that are owned by a company in the majority times, they're connected to a single network. Cloud-based applications might not be identical to the ones on the premises. This is the reason the application needs to undergo major changes before it can be installed and the dependencies it has to be transferred with the cloud. Moving applications that are hosted on-premise towards cloud computing has become referred to by the term cloud migration. The following Amazon Web Services Migration article will highlight the key factors to think about before transfer your application to the Cloud. Learn more about the best methods to utilize Amazon Web Services with the AWS Cloud Migration Course.

Step 1: Assessment

The first step to determine if the application can be described as "cloud-ready". This is the time to examine whether the application can be used with AWS-based services and if we need to perform any necessary implementation or modification to the design in order to make the transition to AWS. This is the first measure to determine the feasibility of the move and to identify any loopholes that could be exploited to limit the risk. It will contain a detailed financial assessment, which allows us to determine TCO and the savings that could be realized by a successful TCO reduction.

Step 2 : Implementation Change

In this phase of the process of transferring to cloud, an application needs to be updated and also undergoes design and architectural changes. This is the longest since it may involve multiple design and re-platforming procedures in a limited manner till the app is at desired state. This may include modifications to the code, changes to the architecture or infrastructure change and so on and on.

Step 3: Data Migration

After the implementation is completed it's time to transfer the static files as well as dependencies and tables for databases to their respective AWS services. This may include shifting the databases that are already in use (MySQL, Oracle, Sybase) to Amazon RDS/Aurora, as and transferring the static file and its dependencies to Amazon S3. It could be a lengthy procedureas older software may contain large quantities of data within their database. After the cloud migration process has taken place, an review of comparison will be required to determine if the information from an on-premise database within Amazon RDS and Amazon RDS corresponds.

Step 4: Application Migration

It involves the transfer process of the app and the setting up of it to Amazon services like EBS and EC2/EBS, as well as assigning load balancers for them and making sure they have capacity. If the app is being containerized it is essential to make an entry in ECR and then move it onto AWS Fargate.

Phase 5: Operate, Test and Test

This is the main stage of validation, in which we test the application to ensure they work flawlessly . In this stage we assess how cloud-based software against the on-premise versions of them to determine that the cloud-based transition was successful.

If you want to move an application that is running on premises to AWS it must follow these five steps. A few of the steps can be time-consuming or repetitive, and prone to failure. If we must deal with many applications on our premises, the risk and time take up a significant amount.

So, how can we cut down the amount of time and effort required to complete these tasks by making use of an automated system that could complete this procedure in a short time with no effort on our part? At Hexaware we've launched Amaze(tm) to help with applications. It's a enterprise cloud-based adopter suite of products which will streamline these steps, and help speed up cloud migration of apps.
