Cloud migration gets harder | InfoWorld

The chart below depicts the number of applications migrated over time in blue, and the degree of difficulty of moving those applications in orange. This is a fictional collection of applications; however, the concept that difficulty increases the more you migrate affects enterprises large and small as they move to the public cloud.  

See this chart:

What’s occurring is easy to explain, but the solution to the problem is not. 

Simply put, the applications and databases that are more modern, better designed, and built to be portable are the first to relocate to the clouds. This for good reason: The cloud teams want to get some wins on the scoreboard and can do so by removing risk and reducing the degree of difficulty. This is actually my advice as enterprises begin their journey.

Predictably, as the number of well-designed and modern applications that can be easily migrated decreases, migration teams are forced to face applications that are not as well designed or are built on older platforms that may not have an analog platform yet in a public cloud. Legacy applications come to mind, but also any application that needs significant refactoring to get it running correctly on a public cloud. 

As many of the enterprises approach the middle of the migration process, the degree of difficulty increases significantly, as shown in the chart, and it’s killing migration productivity. So, how does an enterprise that’s already freaked out about the vulnerabilities exposed in the pandemic get the remaining applications out of the enterprise data center?
