What’s next for serverless architecture?

Automatic distribution of logic and data to the edge will bring minimal latency to end users, without provisioning, scaling, or configuration worries for developers

New serverless functions, such as Cloudflare workers and StackPath Serverless Scripting, are pushing serverless functions to the edge. They aim to bring functions as close to the end user as possible to reduce latency to an absolute minimum. Cloudflare workers have 194 points of presence while StackPath has 45-plus locations. 

Why is this new edge architecture gaining traction now? When we consider the evolution of this transformation from IaaS to edge serverless, one stumbling block has always held us back: How to handle dynamic data? Although we’ve had services like Amazon S3 to host relatively static data, real databases have struggled to deliver a serverless experience. That’s because it’s incredibly hard to build a distributed system that is strongly consistent.

The serverless building blocks in the cloud work like Legos. Developers can combine the building blocks they need and stop worrying about scaling or distribution. 

Today, we have serverless databases with built-in security that open the door for a new breed of applications—applications that scale in a globally distributed way by default. Since that door has opened, many developers have begun looking for ways to replace parts of their back end with microservices and APIs, opening up a new market for many SaaS providers.

The end result will be an ecosystem of building blocks that work like Legos. Soon developers will combine the building blocks they need and stop worrying about scaling or distribution.
