Introduction

AWS Solutions Constructs is an open-source extension of the AWS Cloud Development Kit (CDK) that provides multi-service, well-architected patterns for rapidly defining solutions in code in order to create predictable and repeatable infrastructure. The goal is to help developers build solutions of any size faster by using pattern-based definitions for their architecture.

In other words, it is a method of creating architecture in an opinionated manner while utilising AWS best practices. It is also an excellent presentation of the AWS CDK capabilities (most notably reusability and modularity), as well as a model example of how it can be used.

AWS Solution Constructs Hierarchy

The hierarchy of the AWS Solution Constructs can be classified into three parts.

AWS Cloudformation

The hierarchy begins with the creation of the Infrastructure as a Service (IaS) service on the AWS cloud. Using declarative YAML or JSON templates, you can define entire cloud architectures. These templates are incredibly powerful mechanisms for building infrastructure as code.

Example code defining Cloudformation

"aws_queue 1234567": {
    "Type": "AWS:: SQS::Queue",
    "Properties": {
    "MaximumMessageSize": 3416,
    "QueueName": "aws-demo-queue"
    }
}

AWS Cloud Development Kit (CDK)

The AWS Cloud Development Kit (AWS CDK) is a free and open-source software development framework that allows users to define cloud application resources in familiar programming languages. AWS CDK models your applications using the familiarity and expressive power of programming languages. It provides high-level components known as constructs that preconfigure cloud resources with proven defaults, allowing you to easily build cloud applications.

The AWS Cloud Development Kit (AWS CDK) adds an abstraction layer over confirmation templates, allowing you to define your infrastructure using conventional programming languages rather than declarative markup.

Using the CDK, our code is changes to:

new sqs.Queue (this, 'aws_queue', { 
    queueName: 'aws_queue', 
    maxMessageSizeBytes: 3416,
});

AWS Solutions Constructs

AWS solutions constructs are implementations of common architectural patterns that can be plugged into your CDK stacks on their own or in conjunction with other solutions constructs. They are all built on top of the CDK, which in turn is built on top of cloud formation. Constructs enable you to combine pre-built, well-architected patterns and use cases that perform common actions in a scalable and secure manner using cloud services.

Below is the example of AWS-SQS lambda, a construct that deploys an SQS-Queue along with a lambda function that’s invoked whenever a message is stored in the queue.

new SqsToLambda (this, 'SqsToLambdaPattern',{
 lambdaFunctionProps: {
runtime: lambda.Runtime. NODEJS_10_X,
handler: 'function.handler',
code: lambda.Code.fromAsset (`lambda)
},


queue Props: {
maxMessageSizeBytes: 3416,
queueName: 'aws_queue'
});

Features of AWS Solution Constructs

The features of the AWS Solution Constructs are:

  • It is built on top of the open-source software development framework AWS Cloud Development Kit (CDK).
  • It creates a model of your system using object-oriented techniques.
  • It facilitates sharing and reusing our solution as a library.
  • It organises our solutions into logical modules.

Benefits of AWS Solution Constructs

There are various benefits of the solution constructs in the AWS. Some of them are discussed below.

Saves Time and Effort

The use of AWS Solution Constructs shortens the time and effort required to deliver a production-grade application. Users have immediate access to a large and growing repository of dozens of multi-service architecture patterns spanning the most commonly used AWS Platform combinations. These patterns can be reused and assembled into production-ready architecture.

Well-Architected Applications

AWS carefully examines all AWS Solutions Constructs, using best practices established by the AWS Well-Architected Framework. This means that the default settings for any given Construct's services are configured with the Well-Architected Framework, thereby reducing the effort required to ensure best practices for the AWS Cloud are followed.

This allows the users to consistently create their own well-architected applications.

Infrastructure-as-Code

You can define your infrastructure using familiar programming languages and logic and then build your entire application using Constructs without leaving your IDE.

Use Cases

Some of the use cases of the AWS Solution Constructs are discussed below.

Static Websites

AWS Solution Constructs find their use to create a simple static website using Amazon S3, CloudFront, and AWS Lambda.

Serverless Image Handler

Using AWS Solutions Constructs, we can dynamically manipulate image data by leveraging Amazon CloudFront, Amazon API Gateway, AWS Lambda, and Amazon S3.

Serverless Web App

Using AWS Lambda, Amazon API Gateway, Amazon DynamoDB, Amazon Cognito, and Amazon S3, we can create a simple serverless web application with an HTML-based user interface and a backend RESTful web service.
