What is AWS (Amazon Web Services) Lambda Function?

AWS Lambda is an Amazon serverless computing system that runs code and automatically manages the underlying computing resources like (EC2). It is an event-driven computing service. It lets a person automatically run code in response to many types of events, such as HTTP requests from the Amazon API gateway, table updates in Amazon DynamoDB, and state transitions. It also enables the person to extend to other AWS services with custom logic and even creates its own back-end services. For example, just write the code and then upload it as a .zip file or any container image. The service works by running code on high-availability computer infrastructure. It then performs all the administrative duties of that compute resource such as:

providing maintenance on the server and operating system, auto-scaling and managing the person’s capacity provisions, handling security patch deployment lambda extensions code, monitoring, logging, and concurrency function blueprints. AWS lambda is very helpful when you know how to write code but you don’t know how to provision the underlying infrastructure in AWS. AWS lambda will scale up the applications rapidly when there is sudden incoming traffic and scale down to zero when the incoming traffic is reduced.

AWS Lambda

AWS (Amazon Web Services) function is the new computing system that offers a variety of benefits like real-time data processing and custom back-end service. With so much information available about AWS Lambda, it can be hard to know what it is without an introduction.

How Does AWS (Amazon Web Services) Lambda Functions Work?

Start off by uploading the code to AWS Lambda. From there, set up the code to trigger from other AWS services, HTTP endpoints, or mobile apps. AWS Lambda will only run the code when it’s triggered and will also only use the computing resources needed to run it. The user has to pay only for the compute time used....

Pricing of AWS (Amazon Web Services) Lambda Function

AWS lambda pricing is based on the no.of requests made to your function and the time it has taken to execute the function. The following are the pricing factors to be considered for AWS Lambda. As previously mentioned, with AWS Lambda user only pays for what he uses, factoring in the number of requests and duration of the execution of the code. No charges are taken for creating lambda functions. Lambda considers a request to be each time it starts executing in response to a trigger such as an event notification or an invocation volume. The duration of the code is calculated from the moment the code begins executing until it returns or is terminated. If one is unsure about whether AWS Lambda is the right choice or not, there is a free tier option available to try. This option includes 1M free requests per month and 400,000 GB-seconds of compute time per month....

Advantages of AWS (Amazon Web Services) Lambda Function

Zero Server Management: Since AWS Lambda automatically runs the user’s code, there’s no need for the user to manage the server. Simply write the code and upload it to Lambda. Scalability: AWS Lambda runs code in response to each trigger, so the user’s application is automatically scaled. The code also runs in parallel processes, each triggered individually, so scaling is done precisely with the size of the workload. Event-Driven Architecture: AWS Lambda function can be triggered based on the events happing in the aws other service like when the file or video is added to the S3 bucket you can trigger the AWS Lambda function. Automatic High Availability: When there is high demand or high incoming traffic aws lambda function will automatically scale the servers. Affordable: With AWS Lambda, one doesn’t pay anything when the code isn’t running. The user has to only be charged for every 100ms of code execution and the number of times his code is actually triggered....

Disadvantages of AWS (Amazon Web Services) Lambda Function

Latency while starting: While aws lambda is going to be activated after a long gap it will take some time to initialize the service which is required to deploy the application at that time end users will face latency issues. Limited control of infrastructure: Behalf of your lambda function is going to take of underlying infrastructure so you will have very limited control over undelaying infrastructure. Time Limit: AWS Lambda enforces a maximum execution time limit for functions, which is currently set to 900 seconds (15 minutes). If your function exceeds this time limit, it will be forcibly terminated. Vendor Lock-In: If you want to execute the lambda function then you need the support of any cloud provider as here we are using AWS because it is widely used in the market. Limited Computing and Memory Options: Limited configuration is there on the memory and CPU configuration. The predefined memory configuration was 120 MB to 120 GB and memory configuration determines the corresponding CPU power....
