Introduction:
Serverless is a new way to build apps. In serverless, you do not have to worry about servers. You just write code. AWS does the rest. It runs your code and takes care of everything. This makes your work easy. In 2025, more companies are using serverless. It saves time. It saves money. It is smart and fast.
If you want to learn serverless, you can take an AWS Online Course. This course will teach you all the tools step by step. You will learn how to make apps that are small, fast, and easy to change.
Why Serverless Is Growing in 2025?
In 2025, serverless is everywhere. It helps teams work faster. You only pay for what you use. There are no idle servers. You do not need to manage machines. Developers can focus on building apps.
Companies like serverless because it grows with demand. If more users come, AWS adds power. If users go, AWS removes extra space. You save cost and time. Serverless goes hand in hand with other AWS services.
Tools Used in Serverless on AWS
AWS has many tools that help in serverless apps. Here are some of the top ones:
| Tool Name | Use Case |
| AWS Lambda | Runs code without servers |
| API Gateway | Sends web requests to functions |
| DynamoDB | Stores app data easily |
| S3 | Saves files and media |
| Step Functions | Manages app tasks in order |
These tools work together. You can build full apps without any servers. Lambda is the heart. It runs your code. API Gateway takes user requests. DynamoDB stores data. Step Functions manage flow. S3 holds images or files.
Steps to Build a Serverless App
Here are the steps using them you can build a serverless app:
- First, make a small Lambda function.
- Use API Gateway to connect to the internet.
- Save data in DynamoDB.
- Store files in S3.
- Use Step Functions if you have many steps.
You can use CloudFormation or SAM templates to set this up fast. These tools help you repeat the same setup again later.
