Amazon Web Services has added five categories related to migration to the AWS Partner Network (APN) to encourage enterprise cloud migration. The AWS Migration Competency was unveiled in an announcement on Wednesday, along with dozens of initial launch partners providing migration services.

AWS Migration Competency partners are grouped by five sets of services. The solutions and experience of the partners can help businesses through all stages of complex migrations, from discovery and planning through operations, AWS said.

AWS already offers a Professional Services Cloud Adoption Framework, and launched its Database Migration Service in October to move enterprise databases to AWS Aurora, but as Bill Kleyman pointed out in January, working with heterogeneous storage ecosystems requires expertise.

“More and more, I hear from customers who want to migrate large-scale workloads to AWS, and seek advice regarding their cloud migration strategy,” said AWS Chief Evangelist Jeff Barr in a blog post.

With over 30 percent of the cloud infrastructure market already, and a lead among public cloud providers for enterprises, AWS room to grow its revenue from enterprises is increasingly among cloud adoption laggards and business that might require a little more help and reassurance then the pioneers of public cloud use.

AWS announced a partnership with Ericsson in February to encourage telecom cloud migration by building cloud innovation centers.
