AWS Lambda: The Definitive Guide On It

An approach to creating and delivering applications and services without the need to manage infrastructure is known as serverless architecture. Amazon Web Service Lambda is one of the crucial tools for running application code while developing serverless applications.

This post will teach you more about AWS Lambda. Additionally, you will obtain a comprehensive grasp of how Amazon Web Service Lambda functions, as well as its use cases, advantages and disadvantages, and the processes necessary to use it. Continue reading to learn more details about Amazon Web Service Lambda.

What Is AWS Lambda?

Serverless, event-driven compute service known as Amazon Web Service Lambda is provided by Amazon as a component of Amazon Web Services. It is a computing service that automatically maintains the computing resources needed by that code and executes code in response to events. Lambda functions may perform a variety of tasks, including serving web pages, processing data streams, utilising APIs, and establishing connections to other AWS services.

When an AWS service event occurs, such as uploading or removing files from an S3 bucket or sending an HTTP request to the Amazon API gateway, Amazon Web Service Lambda puts code into action.

You can focus on your core product and business logic instead of managing Operating System (OS) Access Control, Patching, Right-sizing, Provisioning, Scaling, and other related tasks thanks to Amazon Web Service Lambda.

How Do AWS Lambda Function?


Each Lambda function has its own execution container. When a function is created, Lambda bundles it into a fresh container, that is run on a multi-tenant machine cluster under the management AWS. Before the functions begin to run, the necessary RAM and CPU resources are allotted to each function’s container. The RAM allotted at the beginning is multiplied by the length of time the function was executing after it has finished. The amount that customers are subsequently charged depends on the amount of memory provided and how long it takes the function to complete.

The whole infrastructure layer of Amazon Web Service Lambda is managed by AWS. Although customers have little control over how the system operates, they also don’t have to worry about keeping the underlying computers up to date, avoiding network conflicts, etc. because AWS takes care of all of that for them. Users can also save time on operational tasks by using Amazon Web Service Lambda because the service is fully managed.

Why is AWS Lambda a Crucial Aspect of Serverless Architecture?


Amazon Web Service Lambda is one of the essential solutions for running the application code while creating Serverless apps.

You’ll require the following to create a full Serverless stack:

  • An algorithmic service
  • Service for databases
  • A service for HTTP gateways

Lambda is the main computing service offered by AWS. Along with API Gateway, DynamoDB, and RDS, it connects to a wide range of other AWS services and forms the basis for Serverless solutions for AWS users.

Many popular programming languages and runtimes supported by Lambda, making it suitable for a variety of Serverless developers.

You can launch an application using Amazon Web Service Lambda without setting up or managing servers. It is a computer system that relies on happenings. When an event trigger is set up, Lambda used to execute the code.

What are some Amazon Web Service Lambda use cases?


The fundamental elements of Amazon Web Service Lambda applications are Lambda Functions and Triggers. A Trigger is the AWS service or application that invokes the Lambda function, whereas a Lambda function is the code or runtime framework that handles events.

Due to Lambda’s architecture, it can offer considerable advantages over conventional Cloud Computing installations in the following situations:

  • The duration of a single task is brief.
  • Most tasks are independent of one another.
  • The application’s workload varies greatly between its lowest and highest settings.

Following the guidelines are some typical use cases for Amazon Web Service Lambda:

Scalable APIs: When building APIs using Amazon Web Service Lambda, a single HTTP request may served by a single Lambda function run. Various portions of the API directed to different Lambda functions using Amazon API Gateway. Individual functions scaled dynamically via Amazon Web Service Lambda according to demand, allowing different parts of your API to scale depending on usage levels at any given time. This makes API deployments both versatile and cost-effective.

Processing files: Assume you have a photo-sharing app. Your app could allow users to upload photographs, that are saved in Amazon S3 bucket by the app. Then, your programme creates a thumbnail version of each user’s image for display on their profile page. You may create a Lambda function that creates thumbnails automatically in this situation.

Mobile Apps: Let’s say you have a personalised mobile app that creates events. You may develop a Lambda function to handle events provided by your own application. For instance, you could set up a Lambda function in your own mobile application to handle clicks.

Data processing: Lambda functions are made to process data in an event-based manner. Combining Amazon Web Service Lambda with data sources like Amazon DynamoDB and triggering a Lambda function for particular kinds of data events is straightforward. Lambda is a good fit for notifications, counters, and analytics because you may use it to perform a task each time a DynamoDB item created or updated, for instance.


Consider developing a website and deciding to put the backend logic on Lambda. If you want to call your Lambda function through HTTP, you may use Amazon API Gateway as the HTTP endpoint. The API may then used by your web client, and API Gateway will direct the request to Lambda.

What advantages does utilising AWS Lambda offer?


The following are some benefits of utilising Amazon Web Service Lambda:

  1. Reduced Cost

You only pay for the compute resources your functions use in Amazon Web Service Lambda, along with any resulting network traffic, so it operates on a pay-as-you-go basis. Your cost is solely based on the amount of time your application used; none of the fees you pay at the end of the month go toward any unused minutes of server time.

  1. Infrastructure that is fully managed

You don’t need to worry about the underlying servers because your functions operate on the managed AWS infrastructure; AWS takes care of this for you. This can lead to significant cost savings on operational duties like network layer maintenance and operating system updates.

  1. Integration of the Company with Other AWS Products

You can build completely working apps inside your Lambda functions thanks to Amazon Web Service Lambda’s interaction with services like DynamoDB, S3, and API Gateway.

  1. Allow for a Wide Range of Use Cases

Daily Tasks, Notifications, Processing S3 Objects, Automated Chatbots, and many more use cases benefit greatly from the benefits of AWS Cloud.

  1. Automation of Scale

Your function generated into instances as needed by Amazon Web Service Lambda. It doesn’t matter whether you need 3 requests one minute and 2,000 the next; serverless technology can accommodate any unforeseen growth in demand. It just does everything on its own.

AWS Lambda’s limitations


The following are some Amazon Web Service Lambda limitations:

  1. Initial Cold Start Time

When function is started in response to an event, there could be a little delay before the function really starts working. Lambda is inappropriate for latency-critical applications since latency might be high as 5-10 seconds if your function not used in the last 15 minutes.

  1. Not Always Economical

You only pay for the function runtime you actually use on AWS (plus any associated charges like network traffic). For particular use patterns, such cron tasks or other on-demand processes, this can lead to considerable cost reductions. However, when your application’s demand increases, the cost of using AWS increases proportionally and may end up being more expensive than using identical infrastructure on AWS EC2 or other cloud providers.

  1. Limited Number of Runtimes Supported

Custom runtimes may be added to Amazon Web Service Lambda, although doing so might be time-consuming. You can use AWS EC2 or any other Cloud provider if Lambda does not support the version of your programming language.

4. Limits on Function

The following list includes certain AWS Functions restrictions:

5. Execution Clock: A Lambda function will time out after 15 minutes of use. This restriction can’t changed. Amazon Web Service Lambda might not be the ideal option for your needs if your function often runs for more than 15 minutes.

6. Memory Availability: Lambda functions have access to 128MB to 3,008MB of RAM, in 64MB increments.

7. Concurrency: With a single AWS account, all Amazon Web Service Lambda functions are by default limited to 1,000 concurrent executions.

8. Payload Size: When used to activate Lambda functions in response to HTTP requests (i.e. when creating a web application), the maximum payload size that Amazon API Gateway can handle is 10MB.

9. Code Package; Lambda code packages not exceed 50MB in size when compressed, and 250MB when they are uncompressed.
