Serverless Computing

What is Serverless Computing?

Serverless computing, also known as Function as a Service (FaaS), is a cloud computing model that abstracts server management and focuses on application functionality. Instead of maintaining servers, developers can focus on their applications and business logic, leaving the infrastructure management to the cloud service provider.

How Does Serverless Computing Work?

In serverless computing, a third-party service provider hosts applications, and developers don’t need to worry about server operations. When a specific event triggers, the serverless architecture runs the function. Developers only pay for the execution time of their functions, not for idle server time.

Key Features of Serverless Computing:

  • Automatic Scaling: Serverless computing automatically scales applications in response to demand. This makes it an excellent choice for applications with unpredictable or highly variable workloads.
  • Cost-Efficient: With serverless computing, you only pay for what you use. This can lead to significant cost savings compared to traditional server-based hosting.
  • Reduced Operational Management: Because the service provider manages server infrastructure, developers can focus on building great applications instead of managing servers.

Advantages of Serverless Computing

Serverless computing offers several advantages for web developers and administrators, including:

  • Increased Productivity: Developers can focus more on writing code and less on managing servers or worrying about infrastructure.
  • Cost Savings: You only pay for what you use, meaning you’re not spending money on unused server capacity.
  • Scalability: Serverless computing automatically scales to meet your application’s needs, accommodating spikes in traffic without any manual intervention.


Serverless computing is a powerful tool in the arsenal of web designers, developers, and administrators. By abstracting away much of the infrastructure management, it allows for faster development, more efficient scaling, and significant cost savings. With these benefits, it’s no surprise that serverless computing is becoming an increasingly popular choice for web application development.
