Lambda Intro. Amazon Web Services Lambda
AWS Lambda is an Amazon Web Services event-driven computing cloud service that lets developers design functions on a pay-per-use basis without needing to deploy storage or computation resources. This is also known as function-as-a-service (FaaS).
Benefits
One of the key advantages of AWS Lambda is that it removes server maintenance from the IT professional’s responsibilities. Amazon maintains the servers via AWS Lambda, allowing developers to concentrate on building application code.
AWS accepts code written in a number of different programming languages. Node.js, Python, Java, and C# are among the AWS Lambda languages. To create functions, developers can utilize code compiler tools like Maven or Gradle, as well as packages.
The amount of computation and storage resources you may utilize to perform and store functions on AWS Lambda is limited. The restrictions shown below are per-region and can be increased. Use the Support Center console to seek a raise.
Services available
Thousands of services are available on AWS, with approximately 2,000 new ones introduced in 2018. The AWS Lambda console is used by AWS to assist users in monitoring and managing their Lambda applications. Stacks launched in AWSCloudFormation using the AWS CloudFormation UI, the AWS Serverless Application Repository, the AWS CLI, or the AWS SAM CLI are included in the menu.
Enterprises now utilize AWS Lambda.
As of October 2019, here are four prominent companies that are adopting
AWS Lambda:
iRobot, the creator of the internet-connected Roomba robotic vacuum, is employing a serverless architecture to construct the next generation of connected gadgets for the smart home.
MLBAM: Major League Baseball’s digital arm, Statcast, provides broadcasters with real-time game-play statistics. MLBAM utilises AWS Lambda to enrich and process raw data, boost speed, scalability, and analyse enormous amounts of data, and distribute it to their fans.
Guardian News Media -To create dependable processes, the publisher of the Guardian and the Observer utilises AWS Step Operations to manage AWS Lambda functions.
AWS Lambda@Edge
AWS Lambda@Edge is a service provided by Amazon Web Services.
With the launch of its Lambda@Edge service, Amazon enabled serverless computing technologies throughout its global locations. It allows developers to run Lambda code at edge locations across the world that are closer to end users, lowering latency.
AWS Lambda@Edge functions are triggered by Amazon CloudFront Events and deliver location-specific content to end users. When a function activates, Lambda@Edge executes code, allowing it to grow to the amount of the demand. AWS Lambda@Edge allows developers to manipulate HTTP replies and cookies, execute network calls, and run A/B testing.
AWS Lambda is used by developers in a variety of ways.
Developers can use the Lambda dashboard, command-line interface (CLI), or software development kit to list, remove, update, and monitor functions (SDK). AWS CloudWatch is used to execute infrastructure-related tasks including server and operating system maintenance, patch deployment, and logging. Third-party logging application programming interfaces (APIs) are also supported by Lambda, and developers may use the Amazon API Gateway service to link custom API endpoints to Lambda.
