Serverless Computing

What is Serverless Computing?

Serverless Computing is a cloud computing execution model where the cloud provider dynamically manages the allocation and provisioning of servers. This model allows developers to build and run applications and services without worrying about server management. It is used for a variety of applications, from simple CRUD apps to data processing and IoT backends.

Why is Serverless Computing Important?

• Eliminates the need for server management.
• Improves cost efficiency by charging only for the resources used.
• Scales automatically with the application's needs.
• Speeds up deployment and time to market.
• Facilitates a focus on code and business logic rather than infrastructure.

How Does Serverless Computing Work and Where is it Used?

Serverless Computing works by abstracting the server layer from the development process. Developers deploy code, and the cloud provider automatically handles the execution, scaling, and maintenance. It is widely used in building web applications, APIs, event-driven processing systems, and big data applications.

Key Takeaways:

• Cost-Efficiency: Only pay for the compute time you consume, without incurring costs for idle server capacity.
• Scalability: Automatically scales with the application's demand, without manual intervention.
• Focus on Development: Enables developers to concentrate on writing code rather than managing servers.

Real World Example:

A media company uses serverless computing to handle image and video processing. When content is uploaded, serverless functions are triggered to resize, compress, and distribute the media across various platforms, efficiently managing varying loads without manual scaling.

Use Cases:

• Automated back-end tasks for web applications, like user authentication and database updates.
• Real-time file processing, such as image resizing and video transcoding.
• Event-driven systems, like IoT sensor data processing or real-time analytics.
