The serverless applications has brought a revolution to the cloud based application build and deployment model, so that their management.
What if you could build an application that could support the traffic without having to provision or manage a server? Sounds like a fairy-tale, and it is! AWS users have been keen to find an easier method for deploying serverless applications that is built using API gateways, Lambda functions, and AWS DynamoDB.
Recently AWS has released a ground-breaking model known as the AWS Serverless Application Model (SAM) which makes it easier for engineers to deploy serverless applications using AWS CloudFormation hence adding value to customer business. The AWS Serverless Application Model includes AWS CloudFormation to provide a streamlined way of defining the Amazon API Gateway APIs, AWS Lambda functions, and Amazon DynamoDB tables for your serverless application.
More and more AWS customers are taking advantage of serverless architecture patterns. Some of the main benefits of serverless:
- Move fast, innovate: Focus on application logic, not on infrastructure.
- Cost Savings: Save on DevOps resources. Pay for exactly the number of requests and invocations needed.
- Scale without worry: No additional capacity needs provisioning to handle your workload at peak. The ability of a system to scale easily when in a cloud environment is vastly more useful than the overall output.
AWS SAM provisions AWS CloudFormation and outlines the basic syntax for expressing serverless resources. The design currently covers APIs, Lambda functions and Amazon DynamoDB tables. The requirement is present in Apache 2.0 for AWS partners and also for customers to adopt and extend within their own toolsets supporting others in the ecosystem to embrace and incorporate it into build, deployment, monitoring and management tools with a commercial-friendly license.
Earlier, CloudFormation did not have the specialized resource types optimized for defining serverless applications. At present, you can use new resource types to write CloudFormation templates that define serverless resources with only a few lines of text. Furthermore, two new commands have been added to the AWS CloudFormation CLI to simplify the process of packaging a serverless application and deploying it with CloudFormation.
Build Faster With Serverless Architectures
Develop, test, and deploy from a single environment, to any cloud provider. You need not provision infrastructure or worry about scaling. Serverless teams cut down on the time to market into half.
- Automatic Scaling
- Provider Agnostic
- Rapid deployment
Right now, some of the interesting AWS SAM components available include:
- AWS IoT rules
- Amazon Kinesis objects
- Amazon SNS notifications
- API actions
- S3 objects
- DynamoDB tables
- CloudWatch events
- Alexa events
Using AWS Serverless Application Model, you will be able to create, deploy and manage your Lambda functions in an instant. The landscape of serverless applications is continuing to change with the ecosystem of tooling and processes growing and maturing. While serverless applications take away the huge burden off the developers, however, there are still important principles to apply.
