A cloud migration strategy is a plan which any organization develops to move its systems and applications from on-premises architecture to the cloud.
Not all applications and systems benefit from running on the cloud; that’s why you must indorse the most efficient way to work on it and migrate applications. Therefore, a systematic, documented strategy is essential.
Any strategy needs to start from some barefoot, and then it builds on it. Similarly, the vital first step to creating a migration strategy is getting to know what you have? What are the collections of applications, systems, etc.? Once you have documented existing applications, you need to refer to the most common migration strategies. Gartner is calling 5R; some vendors mentioned as 6Rs or 7Rs. (These strategies are: refactor, replatform, repurchase, rehost, relocate, retain, and retire)
Your organization will fall in these options, and you need to choose based on the workload discovery/assessment.
The decision must consider an organization's requirements, evaluation criteria, and architecture principles.
Implementing cloud or migration to cloud is challenging. Organizations that have built thousands of applications over the past two to three decades require re-architecting to run efficiently, securely, and resiliently in the cloud.
Your next steps are to perform a cloud migration assessment based on your cloud strategy and business objectives. It will help identify the right migration pattern and cloud architecture required to go for the workload. Today we will talk about three vital areas
You could have different business goals to introduce digital products and services to market faster. You want to reduce your technical debt or replace on-premises infrastructure due to the end of life. All these reasons are leading you to migrate to the cloud. However, you need to decide and call which application/system is the right candidate for cloud migration. You need to have a clear understanding of the target application's only requirements and dependencies.
On the other hand, digital transformation forces you to make quick decisions, like Microsoft CEO's famous quote.
“We’ve seen two years of digital transformation in two months.” By Microsoft CEO Satya Nadella
