Serverless Architecture
What is Serverless Architecture
Serverless do require servers but the servers will be managed by Vendor. We need not worry about the infrastructure and its maintenance. This is a one step forward to PaaS (Platform as a Service) which is called as FaaS (Function as a Service) or BaaS (Backend as a Service).
Pros:
- Cost efficient - The provider charges for resources utilized not for the server instance
- Less time to market
- The focus should be on functionality development, not the infrastructure
Cons:
- Not suited for high-performance computing
- Cryptojacker's paradise
- DoS your self
- Startup latency (cold start)
Major Service Providers:
- AWS Lambda - Node.js, Java, C#, Python and Go
- Google Cloud Functions - Node.js
- IBM OpenWhisk - Node.js, Java, Python, Swift
- Microsoft - Node.js, Java, Python
