Descriptions


Cloudflare Workers


Continuing their ongoing efforts to improve the internets global state, Cloudflare started to allow compute at their edge, eventually and essentially becoming a serverless/edge compute provider.

Cloudflare has an impressive global network presence and an even more impressive rate of pushing (open source or free) products to the market.

Unique about Workers is Key Value storage. Cloudflare’s low latency KV data store, optimized for high reads, low writes.

With a rich amount of example code to start out in your code of preference right away!


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.
