Descriptions


Amazon Lambda @ Edge


Amazon Lambda at the Edge functions introduced serverless cloud computing to the masses as early as 2014.

Being the first with a massive user-base has set up Amazon for great success, it took a few years for competitors to offer similar functionality and to actually call the FaaS space a new chapter in cloud compute in general.

Amazon’s [email protected] is Amazon’s first Edge Compute product, however Amazon recently released CloudFront Functions, which brings the compute a lot closer to the end-user.

With Amazon’s gigantic scale, a shift has started with companies that are on the AWS platform to move more and more of their infrastructure to serverless.


Fastly Edge Compute


Fastly, traditionally a CDN, was one of the first CDNs that openly and actively promoted it’s edge worker technology.

Fastly has been open and quick when it comes to adding features and functionality to their Serverless product. The platform is runs on WASM logic (with JIT compilation). All in all, one could expect very fast responses when it comes to running your application on Fastly.

Fastly has a unique online fiddler tool to experiment and try different Edge features and functionality without even having to register, live log tailing and individual end-user request trailing. A notable customer of Fastly’s Edge Compute platform is LoveHolidays.
