API on Serverless: Saving Time and Costs

In today’s world, time is money. Companies offering online services are increasingly choosing serverless solutions, such as AWS Lambda, DynamoDB, API Gateway, and Amazon Simple Queue Service (SQS), to optimize their costs and accelerate product delivery. In this article, we will look at the benefits of using these serverless services, as well as the free options offered by Amazon Web Services (AWS).

Serverless: What Does It Really Mean?

Serverless is an architecture that allows developers to focus on writing code without worrying about managing servers or infrastructure. In the context of AWS, services such as AWS Lambda, DynamoDB, API Gateway, and SQS enable building applications without managing servers or virtual machines. This means there is no need to pay for unnecessary resources, and these services automatically adjust to current workload.

AWS Lambda: Flexible and Cost-Efficient Solution

AWS Lambda is a service that allows you to run functions in the cloud without managing a server. This solution is exceptionally flexible, as it adjusts to actual workload. This means you only pay for what you actually use. AWS Lambda also offers an always-free tier, allowing you to run your code up to a million times a month for free, regardless of how long you’ve had the account.

DynamoDB: Fast and Scalable Database

DynamoDB is a fully managed and fast NoSQL database. It is the ideal solution for storing data that requires quick access and scalability. It is also a service available in the always-free tier, meaning you can store up to 25 GB of data for free, along with 25 write and read operations per second, enough for up to 200 million queries per month.

API Gateway: Easy API Management

Amazon API Gateway is a service that allows you to create, manage, and share API interfaces, including HTTP, REST, and WebSocket. This makes it easy to deliver web services and manage traffic to your AWS Lambda functions. It is the only service on our list with only 12 months of free tier, allowing up to one million queries per month. However, even after 12 months, the cost of this service ranges from $1 to $8 per month for up to a million queries.

Amazon SQS: Queue Management with Messages

Amazon Simple Queue Service (SQS) is a service that allows you to create message queues, useful for tasks that can be performed asynchronously. This service is available in the always-free tier, meaning you can send up to one million messages to the queue each month without charges.

Summary

Using serverless services, such as AWS Lambda, DynamoDB, API Gateway, and SQS, can bring many benefits in terms of saving time and costs. For example, a well-designed application with a thought-out database with about 10,000 monthly traffic will cost less than a small server, and it is also a reliable solution due to scalability, meaning your application will never experience overloads. This allows you to focus on creating valuable applications and services, instead of wasting time managing infrastructure. Serverless is the future of cloud application development, and AWS offers tools that allow you to fully utilize it.
