Serverless Computing
Serverless computing is a cloud computing execution model where the cloud provider runs the server and manages the allocation of machine resources dynamically. Pricing is based on the actual amount of resources consumed by an application, rather than on pre-purchased units of capacity.
Serverless Computing Benefits
Key advantages of Serverless Computing
Lower costs
Serverless computing is cost-effective as compared to traditional cloud providers.
Simplified scalability
Serverless architecture simplifies scaling the code.
Simplified backend code
FaaS allows creating simple functions that independently perform a single purpose.
Quicker turnaround
Serverless architecture can significantly cut time to market.
Serverless Computing Components
Although these components share a few similarities, here are the 2 major components of Serverless Computing:
Backend-as-a-service (BaaS):
BaaS is a service model where a cloud provider offers backend services such as data storage so that developers can focus on writing front-end code.
Function as a Service (FaaS):
FaaS is the layer that executes specific business logic with the cloud provider providing the level of abstraction in terms of executing the business logic.
