Migrate Applications to the AWSCloud with Simple Strategies applied

AWS Migration to AWS Cloud


In this Article, you be learning different migration strategies to help you out with customers for migrating applications to the Cloud. Enterprises plan how to alleviate an application during the second phase of the Migration process which is Portfolio Discovery and Planning. In this, they will specify how they will migrate each application, what’s in their environment, the hard and the easy way to migrate and what the interdependencies are. With this, the organizations can blueprint a customizable plan as they go on with the migration process on what actions they will take on each of the applications in the portfolio and in what order.

Depending on existing license agreement and the architecture the complexity of the migrating application differs. For migrating universe of applications on the range of complexities, you should put a virtualized, service-oriented architecture on the low complexity end of the spectrum and a monolithic mainframe at the high complexity end of the spectrum. Start with low complexity end of the spectrum so that it will easier to complete which will provide you a positive boost. Below are some strategies that will help you migrate your applications successfully.

Lift and Shift (Rehosting):

At the first cloud projects use cloud-native capabilities but for a large legacy migration, the organization looks to scale the migration quickly so that it can meet business case immediately so basically many applications you will find is rehosted. Rehosting Automated Tools like AWS VM Import/Export can be used but customer mostly chooses to do this manually as they learn on how to apply the legacy systems to the cloud platform. When the applications are already running on the cloud it becomes easier to re-architect or optimize.

Cloud Optimization:
In this you don’t have to change the core architecture of the application, you only have to make a few cloud optimizations so that you leverage from the tangible benefit. To reduce the amount of time gets spends managing the database instances you should migrate to the database as a service platform like Amazon RDS or migrate the application to a fully managed platform like Amazon Elastic Beanstalk.

Purchasing different product:

Repurchasing is usually seen as the most common move to the Software as a service platform. Moving an HR system to Workday, a CRM to Salesforce.com and CMS to Drupal and much more.

Re-Architecture:

By using the Cloud native features the application can be developed and architected. Mostly business needs to add features, performance or scale that would be otherwise challenging to achieve in the application’s present environment. If you want to boost agility or improve business continuity then you can migrate from a monolithic architecture to a Service-oriented Architecture. It is expensive but it will be a good market fit which is very beneficial.

Removal:

If you are discovering your application environment you must be seeing the percentage of the functional area own each environment. It is been observed that 10 percent to 20 percent of an enterprise IT portfolio is not useful which can be simply turned off. Well, this will boost the business case which will direct the team’s scarce attention to things that the people use and it will lessen the surface area you want to secure.

Prioritise:

If the application is recently upgraded and you don’t want to migrate some applications then it is suggested that you migrate applications that is crucially necessary for the business. As the portfolio scenario changes from on-premises to the cloud then you can have some reason to retain.
