Using Serverless Architecture
WHAT IS SERVERLESS?
Serverless architecture (also known as serverless computing or function as a service, FaaS) is a software design pattern where applications are hosted by a third-party service, eliminating the need for server software and hardware management by the developer. Applications are broken up into individual functions that can be invoked and scaled individually.
But what are the benefits of a serverless architecture:
- Agility – Since developers are not deploying, managing, or scaling servers when using serverless, organizations are able to abandon infrastructure administration. This dramatically decreases operational overhead. Serverless is highly compatible with a microservices architecture, which entails significant agility benefits as well.
- Scalability – A big advantage of serverless is the scalability it enables, as upgrading and adding compute resources is no longer reliant on the DevOps team. Serverless applications can quickly, seamlessly, and automatically scale up to accommodate spikes in traffic; conversely, these applications also automatically scale down when there are fewer concurrent users.
Pay-per-use – Function-as-a-service compute and managed services charged based on usage rather than pre-provisioned capacity. You can have complete resource utilization without paying a cent for idle time. The results? 90% cost-savings over a cloud VM, and the satisfaction of knowing that you never pay for resources you don't use.
