Cloudflare Workers

Cloudflare Workers allow you to make use of Cloudflare’s Edge Network to distribute your normal JavaScript based functions. 

Serverless functions handle all the underlying infrastructure tasks such as capacity provisioning & auto-scaling, patching, administration and code monitoring. They simply run code in response to events. You no longer need to worry about performance or security considerations. Use functions to process data (data transformation/data enrichment) at scale in realtime or build responsive apps with event-driven communication between decoupled microservices. 

Invoke Cloudflare Workers via Webhooks on Ably.
