Guide to Serverless Computing

What is Serverless Computing:
Serverless computing is a cloud computing model where the cloud provider dynamically provisions and manages the backend infrastructure. Developers can focus on their core product instead of managing servers or runtimes. The provider charges based on the actual computation performed, not pre-purchased capacity.

Why is Serverless Computing important:
Serverless computing is important because it allows developers to focus on their application logic rather than infrastructure. It provides automatic scaling, operational flexibility, increased efficiency, and reduces operational costs.

How Serverless Computing works:
In serverless computing, the cloud provider runs the server and dynamically manages the allocation of machine resources. Developers deploy their code and the cloud provider executes the function only when needed, scaling up to meet the demand of incoming requests.

Exam Tips: Answering Questions on Serverless Computing:
Understand the main concept of serverless computing, its benefits, and how it works. Learn key terms related to serverless computing like Function as a Service (FaaS) and Backend as a Service (BaaS). Remember that serverless computing is not suitable for long-running applications as it is event-driven. Understand the difference between traditional cloud hosting and serverless computing. Be able to discuss scenarios where serverless computing is applicable.

Serverless Computing practice test

Serverless computing, also known as Function as a Service (FaaS), is a cloud computing model that abstracts away infrastructure management, allowing developers to focus on writing and deploying application code. In serverless computing, the cloud provider automatically provisions, scales, and manages the infrastructure required to run the application code in response to events or triggers. The term 'serverless' is somewhat misleading since servers are still involved; however, the cloud provider handles all server management, and users are not required to manage or allocate resources directly. Serverless computing is ideal for event-driven architectures, where applications can execute code in response to events like file uploads, incoming messages, or database modifications. The serverless model helps to reduce operational complexity, improve resource utilization, and allows developers to build applications more efficiently by leveraging third-party services and microservices.
