Serverless Computing: What PMs should know about it?

Serverless computing, often simply referred to as “serverless,” is a cloud computing model that can change the way we think about building and deploying applications. For Product Managers (PMs), understanding serverless can be a game-changer in terms of speed, scalability, and cost-efficiency. In this article, we’ll delve into serverless computing from a PM’s viewpoint, exploring its benefits, challenges, and real-world examples.

What is Serverless Computing?

At its core, serverless computing allows developers to build and run applications without managing the underlying infrastructure. Instead of provisioning and maintaining servers, the cloud provider automatically handles the setup, scaling, and maintenance. Developers can focus solely on the code, and the application will scale automatically with the number of requests.

Benefits of Serverless Computing for Product Managers

1. Cost-Efficiency: With serverless, you only pay for the actual compute time your application uses, not for idle server time.
2. Scalability: Serverless applications can handle thousands of concurrent users without any additional setup.
3. Speed: Faster time-to-market as developers can focus on writing code without worrying about the underlying infrastructure.
4. Maintenance: Reduced operational burden as the cloud provider manages server maintenance and updates.

Challenges and Considerations

1. Cold Starts: Initial delays can occur when a function is invoked after being idle.
2. State Management: Serverless functions are stateless, so managing application state can be a challenge.
3. Vendor Lock-in: Relying on a specific cloud provider’s tools and services can make migration difficult.
4. Complexity: As applications grow, managing multiple serverless functions and their interactions can become complex.

Real-World Examples of Serverless Computing

1. Image Processing: A photo-sharing app can use serverless functions to automatically resize images when they’re uploaded.
2. Data Processing: An e-commerce platform can process sales data in real-time using serverless functions to provide insights and analytics.
3. Chatbots: Serverless can power chatbot logic, responding to user queries without the need for a dedicated server.
4. APIs: Quickly deploy RESTful APIs without setting up servers.

A Quick Mind Map about Serverless Computing

Serverless computing offers a plethora of benefits for Product Managers, from cost savings to rapid deployment. While there are challenges to consider, the advantages often outweigh the drawbacks, especially for projects that need to scale quickly or have unpredictable traffic. As with any technology, it’s essential to evaluate serverless in the context of your product’s needs and goals.
