The cloud has changed the very way companies build, run, and scale applications. One of the more noteworthy platforms in this is AWS (Amazon Web Services), which has been leading the charge throughout this evolution, providing solid serverless computing modules so that organizations can build applications quicker at scale and at a cheaper cost. But if you really want to squeeze every penny from your serverless setup, you need to also learn your way around AWS pricing models (especially if you are working with an AWS reseller and using AWS reseller pricing).
This guide walks you through what serverless computing is on AWS, its advantages, how to develop faster applications, and how to save costs.
What is serverless computing on AWS?
Serverless computing is (as the name suggests) a cloud-native development model where the cloud provider automatically manages the infrastructure. With serverless architecture, developers can write code without having to worry about provisioning or maintaining servers. This model is powered in AWS by services like:
- AWS Lambda: Executes your code in response to events with zero server provisioning.
- Amazon API Gateway: It handles RESTful APIs on a large scale.
- AWS Fargate: Does not manage the server holding the containers.
- Amazon DynamoDB: Serverless (showing a link to the official website) —A fully managed NoSQL database designed for serverless workloads.
- Amazon S3: Fully managed, scalable storage that plays nicely with serverless apps.
Developers can focus on application logic instead of worrying about infrastructure, reducing deployment time with these provisions.
Why Choose Serverless on AWS?
1. Faster Development Cycles
Serverless computing allows developers to concentrate more on writing and deploying code instead of managing infrastructure. This shortens the time it takes to get to production from development.
2. Automatic Scaling
AWS serverless services like Lambda scale automatically dependent on the load, so your application does not fall behind in the event of a high load period and reduces costs as the demand is reduced.
3. Cost-Effective
With serverless, you pay only for what you use. AWS Lambda, for example, charges based on the number of times it is executed, as opposed to provisioning an on-demand, fixed number of servers, which is a much more cost-effective solution.

4. Reduced Maintenance
One advantage of using AWS is that they manage the updates, patching, and server management for you, so the DevOps overhead is lower. This allows teams to devote themselves to the central components of their applications without worrying about keeping the server up and working.
5. High Availability and Fault Tolerance
AWS serverless services are built with high availability and automatic failover—reducing downtime and increasing reliability.
Building Faster with AWS Serverless
1. Define Your Architecture
Make sure you know the parts you want to build before creating your application. A typical architecture would have:
- API Gateway for handling requests.
- Lambda functions for processing logic.
- DynamoDB or RDS for data storage.
- S3 for file storage.
- CloudWatch for monitoring and logging.
2. Use AWS Lambda for Compute
Here is how AWS Lambda works AWS Lambda is a serverless compute service that lets you run code without provisioning or managing servers. You can use Python, Node.js, Java, and more. AWS scales these functions automatically based on demand.
Example use cases include:
- Real-time processing of data streams.
- Running scheduled jobs.
- Implementing backend logic in web and mobile applications
3. Optimize API Performance with API Gateway
Waterline APIs are built on top of Amazon API Gateway, which is a managed service to create, publish, maintain, monitor, and secure APIs. It also integrates with Lambda and supports many features, like caching, authentication, and rate limiting, to improve its performance.
4. Store Data Efficiently with DynamoDB
AWS DynamoDB is a fully managed NoSQL database that integrates well with Lambda. It delivers single-digit millisecond performance, making it ideal for serverless applications needing low-latency data access.
5. Automate Deployment with AWS SAM or Serverless Framework
The manual operation of the infrastructure can hamper the speed of development. Instead, rely on automated tools, such as:
- AWS Serverless Application Model (AWS SAM): A serverless application framework.
- Serverless : A command line tool for building and deploying to serverless.
6. Monitor and Debug with AWS CloudWatch and X-Ray
In a serverless environment, logging and monitoring become even more important.
- AWS CloudWatch logs and metrics for Lambda functions and other AWS resources.
- AWS X-Ray includes tracing to debug and improve performance.
Cost Optimization: How to Build Without Breaking the Bank
1. Understand AWS Reseller Pricing
Using AWS reseller pricing is one of the most effective ways to cut down costs. The AWS reseller also implements effective cost management solutions to the cloud services. AWS resellers also negotiate volume discounts and tailor pricing models that AWS may not provide directly.
2. Use AWS Free Tier
AWS free tier with limited usage (Lambda, API Gateways, DynamoDB use). This is excellent for the development and testing of applications at no cost.
3. Optimize Lambda Execution Time
AWS Lambda pricing is based on execution time and memory consumption. To reduce costs:
- Write fast code
- Optimize Memory Allocation (more memory → faster execution)
- Your PDFs should have low request latency.
4. Take Advantage of Reserved Instances for Databases
For RDS or DynamoDB, use reserved instances if your workloads are predictable. This can result in savings of up to 75% as compared to on-demand pricing.
5. Optimize API Gateway Costs
API Gateway is charged on a per request basis so you must use it judiciously:
- Cache results so that the same data is not fetched with every call.
- Instead of using the HTTP APIs, you should be using AWS WebSocket APIs for real-time applications.
- If possible, use direct Lambda-to-Lambda calls to avoid API Gateway.
6. Store Files Cost-Effectively
It has different storage classes in Amazon S3, like S3 Standard-IA (Infrequent Access) and Glacier, for storing files that aren’t accessed often at a lower price.
7. Monitor and Adjust

Conclusion
By using serverless computing on AWS, businesses of all sizes are able to innovate faster and decrease operational costs. Using this approach along with AWS’ serverless services (AWS Lambda, API Gateway, DynamoDB, etc.), developers can spend more time focusing on innovating and less time upset about maintaining infrastructure.
Having an AWS reseller and using AWS reseller pricing are also some of the best strategies that can aid businesses in effectively optimising their cloud costs. When architected, designed, and implemented well while paying attention to cost optimisation, you can scale your applications seamlessly while achieving high performance without burning a hole in your pocket.
