AWS Lambda cost saving tips Optimize your AWS Lambda costs with these tips


Choose Memory Wisely

Rightsizing your Lambda function is essential. You must find a good balance between CPU and memory usage. You can use AWS Lambda Power Tuning profiler or AWS Compute Optimizer to find a sweet spot for your function. Higher memory functions might be more expensive, but they might also finish their work faster.


Utilize Savings Plan

With the AWS Savings Plan you can reduce your EC2, Lambda and ECS Fargate costs. Ideally you would pick the no-upfront savings plan for a longer term. If you are using AWS organizations, make sure to share the savings plan. Purchase saving plans incrementally so you can stack them and utilize them fully.


Analyze Your Usecase

Depending on your use-case Lambda might be great if you are running a fully event driven architecture, but it can get expensive at scale. If you have a fixed and consistent workload (for example a web server with high load, with a lot of idle time in requests) it might be more cost effective being served by Fargate.

About Alex I am your AWS cost saving guru, ready to slash your AWS costs!

As a CTO at various start-ups and scale-ups, I've seen too often how AWS costs can sneak up on you. It used to be something we'd only think about when there was a problem—either it wasn't working like we needed it to, or the expenses were through the roof. I took my know-how in AWS and made it my goal to change that. Now, I use a simple rule to make a big impact: focus on the few changes that make the biggest difference in cutting costs.

I look at your AWS bills with a fine-tooth comb and find where you can save money without losing performance. It's about being smart with your resources and making sure AWS works for you, not against you. By doing this, I help your teams do more with less, and make sure we keep your cloud spending in check.

About AWS Lambda Service information & pricing

About AWS Lambda

AWS Lambda is a serverless compute service that allows code execution from an uploaded .zip or container image at any scale. Pay only for used compute time. Ideal for various applications like file/stream processing and web/IoT backends. Due to its serverless nature it is important to optimize your cold starts. For instance, placing database connection handlers outside the function handler code.

AWS Lambda pricing

AWS Lambda pricing depends on function execution duration, number requests made, memory size allocated to the function, and the aggregate monthly duration of functions on the same architecture and region. Ephemeral storage cost varies with allocated amount and execution duration. To get a better price performance for your Lambda functions you might consider using Graviton architecture.
