Headers modification at viewer or origin request/response in CloudFrontĪWS Lambda is a compute service mainly used to run background processes.Insertion, updation and deletion of data in Dynamo DB table.The events can trigger AWS Lambda are as follows −

Since AWS Lambda relies completely on AWS for the infrastructure, you cannot install anything additional software if your code demands it. Incase if your function needs more time than what is allocated, it will get terminated as per the timeout specified on it and the code will not be fully executed. You need to carefully analyze your code and decide the memory and timeout. In spite of many advantages, AWS Lambda possesses the following disadvantages −

Take a look at the free services offered by AWS free tier.

It gives you service for free for 1 year. You can use AWS Lambda for free by getting a login to AWS free tier. Besides AWS console, we have AWS-cli to create and deploy code. It also has support for serverless framework which makes writing and deploying of AWS Lambda code easy. For writing your code, you can use AWS online editor, Visual Studio IDE, or Eclipse IDE. There are many options available for Lambda for authoring and deploying code. These are widely used languages and any developer will find it easy to write code for AWS Lambda. Multi Language SupportĪWS Lambda supports popular languages such as Node. You need not pay if the function is not executed. AWS always charges for the execution time used.

If you specify your AWS lambda code to be executed in 500ms and the time taken to execute is just 200ms, AWS will bill you only for the time taken, that is 200ms of execution instead of 500ms. So for a 500ms execution, the billing will be after every 100ms. Billing based on UsageĪWS Lambda billing is done on memory usage, request made and the execution, which is billed in increments of minimum 100ms. AWS CloudWatch collects all the logs, which helps in understanding the execution flow and in the debugging of the code. Log ProvisionĪWS Lambda gives the details of number of times a code was executed and time taken for execution, the memory consumed etc. It allows you to choose the memory and the timeout required for the code.ĪWS Lambda can also execute parallel requests as per the event triggers. It takes care of maintaining the code and triggers the code whenever the required event happens. This section discusses them in detail − Ease of working with codeĪWS Lambda gives you the infrastructure to upload your code. Advantages of using AWS LambdaĪWS Lambda offers multiple benefits when you are working on it. Step 5 − Remember that AWS charges only when the AWS lambda code executes, and not otherwise.

data is added/updated/deleted in dynamo dB tables.

Step 4 − Executes AWS Lambda Code only when triggered by AWS services under the scenarios such as − For example, event from Amazon S3, Amazon API Gateway, Dynamo dB, Amazon SNS, Amazon Kinesis, CloudFront, Amazon SES, CloudTrail, mobile app etc. Step 3 − AWS Lambda which has the upload code and the event details on which the trigger has occurred. Step 2 − These are few AWS services on which AWS lambda can be triggered. Step 1 − Upload AWS lambda code in any of languages AWS lambda supports, that is NodeJS, Java, Python, C# and Go. The block diagram that explains the working of AWS Lambda in five easy steps is shown below − You pay only for the compute time you consume - there is no charge when your code is not running. AWS Lambda executes your code only when needed and scales automatically, from a few requests per day to thousands per second. What is AWS Lambda?ĭefinition of AWS Lambda as given by its official documentation is as follows −ĪWS Lambda is a compute service that lets you run code without provisioning or managing servers. Note thatAWS Lambda will work only with AWS services. All other tasks and resources such as infrastructure, operating system, maintenance of server, code monitoring, logs and security is taken care by AWS.ĪWS Lambda supports languages such as Java, NodeJS, Python, C#, Go, Ruby, and Powershell. To get working with AWS Lambda, we just have to push the code in AWS Lambda service. The code is executed based on the response of events in AWS services such as adding/removing files in S3 bucket, updating Amazon dynamo dB tables, HTTP request from Amazon API gateway etc.

Monitoring and TroubleShooting using CloudwatchĪWS Lambda is a service which performs serverless computing, which involves computing without any server.
