Re-platform in the cloud – Leveraging the Cloud for Digital Transformation
Re-platform in the cloud
Sometimes referred to as “lift-tinker-and-shift,” it entails making a handful of cloud optimizations to achieve tangible benefits without changing the application’s core architecture. For example, by migrating a Windows-based application running on an older version such as Windows 2008, you can use the migration opportunity to update it to the latest version, such as windows 2022. To reduce the amount of time you spend managing database instances, you can move to an Amazon Aurora, a fully managed database in the AWS cloud.One of AWS’ Database Migration benefits is that moving from one database source or version to a new platform or software version keeps the source database fully operational throughout. That means near-zero downtime during the migration, saving you time and money.Re-platform your services to run in the cloud entails migrating the applications and changing the underlying infrastructure architecture. However, the code of the higher-level services will not be changed. This way, you can leverage your existing code base, languages, and the frameworks you are currently using. It may be a good balance between taking advantage of some of the properties inherent to the cloud, such as elasticity and Scalability, without having to make wholesale changes to your existing applications. It is advisable to use this method when you are comfortable with your current set of applications but you want to take advantage of certain cloud advantages and functionality. For example, you may wish to add failover to your databases without buying the software needed to run this setup reliably. If you were implementing this functionality on-premises, you would have to own all the infrastructure. A specific example is Oracle Data Guard, which allows you to implement this failover but not without having to install the product, and you need enough expertise to ensure that the product is configured correctly. Instead, when you are in a cloud environment, you can leverage the virtualization nature of the cloud, and costs can be shared with other cloud customers.
