Amazon Web Services (AWS) Lambda is a serverless computing service offered by Amazon that allows users to run their code without provisioning or managing servers. One of the key benefits of using Lambda is its pricing model, which is based on the number of requests and the duration of each request.
When it comes to pricing for AWS Lambda, there are two main components to consider: the number of requests and the duration of each request. The number of requests is the number of times your code is executed, and the duration of each request is the amount of time it takes for your code to run.
The cost for each request is $0.20 per 1 million requests, and the cost for the duration of each request is determined by the amount of memory allocated to the function. The more memory you allocate to your function, the higher the cost will be.
In addition to the cost of requests and duration, there are also other costs to consider when using AWS Lambda. For example, if you use other AWS services in conjunction with Lambda, such as S3 or DynamoDB, you will be charged for their usage as well. Additionally, if you choose to use a VPC with your Lambda function, you will incur additional charges for the use of the VPC.
It’s worth noting that AWS Lambda also offers a free tier that allows users to run up to 1 million requests per month and 400,000 GB-seconds of compute time per month at no charge. This free tier is a great way for users to test out and get familiar with the service before committing to a paid plan.
AWS Lambda also offers a feature called “Provisioned Concurrency” for a small additional cost, which allows users to keep their function “warm” and ready to respond quickly to incoming requests, reducing the “cold start” latency that can occur when a function is run infrequently.
In conclusion, AWS Lambda is a cost-effective serverless computing service that charges users based on the number of requests and the duration of each request. Additional charges may apply when using other AWS services in conjunction with Lambda and when using a VPC. The service also offers a free tier and a feature called Provisioned Concurrency to reduce latency. It’s a good idea to understand your usage and requirements to estimate the cost of using AWS Lambda.
