Serverless architecture has become a way for many developers and architects to meet ever-changing business requirements by automatically accessing the capabilities and capacity they need, without the fuss and muss of worrying about operating systems, provisioning servers, addressing storage, and other aspects of the plumbing underneath applications.
To get a clear perspective on how serverless architecture can boost the technology fit in today's enterprises, we turned to Andres Rodriguez, founder and CTO of Nasuni (NAS Unified). Before Nasuni, he was founder and CEO at Archivas, creator of an enterprise-class cloud storage system acquired by Hitachi Data Systems and is now the basis for the Hitachi Content Platform.[1][2]
Q: How should the existing or legacy architecture be phased out in the move to serverless architecture? Is it an instant cut over, or do you recommend a more gradual migration?
Rodriguez: How existing or legacy architecture should be phased out depends on the unique needs of the organization and the applications involved. But one thing is certain: large organizations want to get out of the data center business altogether.
The current move to a serverless architecture - albeit a misnomer because servers are involved - is an inevitable chapter in this evolution. IT executives and application developers don't want to be in the business of provisioning, maintaining and administering servers for the same reasons they first embraced the cloud.
Yes, some organizations will - by necessity - need to make a gradual migration from their existing legacy architecture. And while not an instant cut over, even these gradual transitions will seem fast, particularly when one considers that in many cases it took decades for the
