What is AWS Lambda
- Execute code without the need to manage runtimes, create workload-aware cluster scaling logic, provision or manage servers, or maintain event integrations.
- Execute code for almost any kind of backend service or application. Simply upload your code as a container image or ZIP file, and Lambda will automatically distribute compute execution power and execute your code for any volume of traffic based on incoming requests or events.
- Create Lambda functions in your preferred language (Node.js, Python, Go, Java, and more) then create, test, and deploy them using serverless and container tools like AWS SAM or Docker CLI.
Why Lambda on AWS?
The quickest method to transform an idea into a contemporary, production serverless application is with AWS Lambda, a compute service that automatically maintains the computing resources and executes your code in response to events.
Use Cases
Web Applications
Developers can create robust web applications that automatically scale up and down and operate in a highly available configuration across multiple data centers by integrating AWS Lambda with other AWS services. This eliminates the need for administrative work related to scalability, backups, or multi-data center redundancy.
Learning Machines
Before supplying data to your machine learning model, you can preprocess it using AWS Lambda. You may also serve your model for prediction at scale with Lambda access to EFS, eliminating the need to provision or maintain any infrastructure.
Processing Data
Run code in reaction to triggers, such as user activities, system status changes, or data changes. Lambda may connect to pre-existing EFS file systems or integrate with workflows using AWS Step Functions. It can be activated by AWS services like S3, DynamoDB, Kinesis, or SNS. This enables you to construct a range of serverless real-time data processing systems.
Advantages of Lambda
Server management is not necessary
Execute code without managing or allocating resources. Just create the code and upload it as a container image or.zip file.
Scaling automatically
Regardless of the scale from a dozen events per day to hundreds of thousands per secondautomatically react to requests for code execution.
Pay-per-use pricing
Instead of allocating infrastructure in advance for peak capacity, save money by just paying for the milliseconds of compute time that you really utilize.
Optimization of performance
Use the appropriate function memory size to maximize code execution time and performance. With Provisioned Concurrency, you can react to strong demand in double-digit milliseconds.
Features of AWS Lambda
AWS Lambda executes code in response to events to manage compute resources. Discover how AWS’s comprehensive infrastructure offerings and capabilities enable fast, affordable application development.
Other features of AWS Lambda include the following:
Multiple language support
Back-end code can be executed in Node.js, Python, Java, Kotlin, and C#.
Pictures of containers
To deploy heavier workloads or utilize pre-existing container tooling, you can make a container image for a Lambda function.
You can use instrumentation tools such as AWS X-Ray and Gatling to track the performance of your Lambda function. Additionally, you can leverage third-party log management solutions like CloudWatch to measure concurrency, performance, and invocation.
Serverless compute service on AWS Lambda
Serverless compute service AWS Lambda lets developers run code without server management:
- Event-driven: When a user adds an item to their shopping cart, for example, Lambda executes code in reaction to that event.
- Pay as you go: When your code is not executing, there is no fee; you just pay for the compute time you utilize.
- Automatic administration: Lambda takes care of the computer resources your code needs on its own.
- High availability: Your code is scaled with high availability via Lambda.
- Integration: You can call your code directly from a web or mobile application, or you can configure it to run automatically from other AWS services.
- Security: Lambda guards against unwanted access to client data.
FAQs
Q: What kind of code can run on AWS Lambda?
AWS Lambda provides a simple method for completing a variety of cloud-based tasks. For instance, AWS Lambda can be used to create mobile back-ends that retrieve and modify data from Amazon DynamoDB, handlers that compress or modify objects as they are uploaded to Amazon S3, auditing and reporting of API calls to any Amazon Web Service, and Amazon Kinesis for server-less streaming data processing.
