Understanding Serverless Computing
In this section, you’ll learn the fundamental principles of serverless computing and its key characteristics. Serverless architecture is all about focusing on writing code without having to manage the underlying infrastructure. It allows you to run your applications and services without worrying about provisioning or maintaining servers.
One of the benefits of serverless computing is its scalability. With serverless architecture, your application automatically scales based on the number of incoming requests, ensuring that you don’t have to manually adjust resources to accommodate fluctuating workloads. This can lead to cost savings as you only pay for the resources you use.
Additionally, serverless computing offers high availability. Cloud providers handle the infrastructure management, ensuring that your application is distributed across multiple data centers, reducing the risk of downtime.
Another advantage of serverless computing is its event-driven nature. Your functions are triggered by specific events, such as HTTP requests, database updates, or file uploads. This allows for a more efficient allocation of resources, as your code only runs when needed.
Moreover, serverless architecture promotes rapid development. By abstracting away the infrastructure layer, developers can focus on writing code and delivering value to users without getting bogged down by server management tasks. This can lead to faster time-to-market for your applications.
