What’s next for serverless architecture?

Serverless services are everywhere. The driving force behind an evolution towards a new way of programming, serverless offerings come in all forms and shapes including application hosting platforms, serverless databases, CDNs, security offerings, etc.

Low-level configuration, scaling, and provisioning concerns have been taken away by serverless offerings, leaving distribution as the last remaining concern. Here edge serverless provides a solution by distributing data and compute across many data centers. Edge serverless reduces latency by bringing calculations closer to the user.

Edge serverless is the culmination of an evolution of cloud architectures that began with Infrastructure-as-a-Service nearly 15 years ago. The next stage of that evolution will be to push the distribution of serverless “building blocks” further and make them easier for developers to consume.

Let’s take a closer look at where we’ve been and where we’re headed.

Infrastructure as a Service (IaaS)

The cloud computing revolution started in earnest with the advent of Infrastructure-as-a-Service. With IaaS, companies could move their local infrastructure to hosted “cloud” infrastructure and operate from there. They paid only for the storage and compute hours that they used, and did not need to install or manage any hardware or network.

At first, IaaS seemed expensive, yet companies adopted it very quickly because uptime was guaranteed at a level they could not compete with, while the price of buying and maintaining their own infrastructure often surpassed the IaaS offering. The most important advantage was that the cloud removed hardware maintenance and provisioning, which liberated developers to focus on business value.
