What is Serverless Computing?

Serverless computing is a cloud computing service that allows developers to build and run applications without managing servers. This means you can focus on writing code, and the cloud provider handles everything else—like scaling, server maintenance, and resource management.

How Does Serverless Computing Work?

In a traditional server setup, developers need to provision servers, configure them, and ensure they are always running. With serverless computing, you only pay for the compute time you use. When your code runs, the cloud provider automatically allocates the necessary resources. Once the code finishes, the resources are released. This makes serverless computing a cost-effective solution since you are not paying for idle servers.

Key Benefits of Serverless Computing

1. Cost Savings: Because you only pay for what you use, serverless computing can save money. There are no fixed costs for server management.

2. Automatic Scaling: Serverless systems can automatically adjust to changes in demand. If many users are accessing your app, the cloud provider will provide the needed resources.

3. Faster Development: Developers can quickly build and deploy applications. This agility leads to faster product releases.

4. Reduced Maintenance: Since the cloud provider manages the infrastructure, developers can spend more time coding and less time on server management tasks.

When to Use Serverless Computing

Serverless computing is perfect for applications with variable workloads. If you are building an application that experiences spikes in traffic, such as an eCommerce site during holiday sales, serverless computing can handle the demand efficiently. It is also ideal for microservices architectures, where small, independent functions need to work together.

You can ask them to build a simple application using serverless architecture, such as creating AWS Lambda functions or deploying serverless APIs. This type of test helps you see how well they understand serverless concepts and their ability to implement solutions.

2. Scenario-based Assessments: Present candidates with hypothetical situations related to serverless computing. For example, ask them how they would design a serverless application to handle high traffic during peak events. This not only assesses their technical knowledge but also their problem-solving skills and ability to think critically under pressure.

Using platforms like Alooba can simplify this assessment process. Alooba provides customizable tests specifically focused on serverless computing, allowing you to accurately evaluate a candidate's skills in a structured manner.
