Choosing a FaaS (Function as a Service) provider in 2021

Function as a Service (FaaS) is a cloud computing model where the cloud provider executes a single function in response to an event. It has gained popularity due to its cost-effectiveness, ease of maintenance, and scalability. However, it also comes with some disadvantages such as higher latency and portability issues. When choosing a FaaS provider, factors like workload, latency, pricing, speed of prototype, and compatibility with existing infrastructure should be considered. AWS Lambda, Google Cloud Functions, Azure Functions, Vercel, Gatsby Cloud functions, Netlify functions, Cloudflare Workers, Fly.io, Oracle Functions, IBM Functions, Tencent Cloud, Alibaba Cloud, Redhat Open Shift, and No-Code/Low-Code providers are some of the popular FaaS providers available in the market. FaaS can be used with Hasura through actions and events to design serverless workloads that execute behind a custom query or mutation field, perform custom authentication logic, or react to events happening in your database.
