Descriptions


Fly.io


Fly is an opensource runtime for edge apps, Fly offers a paid hosted version of their product as well. This provider will focus on the paid hosted version. Fly.io is one of the few companies and products that has a full range of tools alongside their actual product, which makes them an ideal candidate for curious developers and new companies to experiment.

Everything they do is docker based, and their networking abstraction is top notch, it’s clear Fly will play a major role in turning the space into a more user-friendly one. Fly’s ambitious mission to make application distribution as ubiquitous as CDNs sets the bar for any contenter willing to compete.


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.
