AWS Cloud Development Kit

Define cloud infrastructure using familiar programming languages

The AWS Cloud Development Kit (AWS CDK) is an open source software development framework to define your cloud application resources using familiar programming languages.

Provisioning cloud applications can be a challenging process that requires you to perform manual actions, write custom scripts, maintain templates, or learn domain-specific languages. AWS CDK uses the familiarity and expressive power of programming languages for modeling your applications. It provides you with high-level components called constructs that preconfigure cloud resources with proven defaults, so you can build cloud applications without needing to be an expert. AWS CDK provisions your resources in a safe, repeatable manner through AWS CloudFormation. It also enables you to compose and share your own custom constructs that incorporate your organization's requirements, helping you start new projects faster.

For customers who prefer Terraform, cdk tf provides the CDK constructs for defining Terraform HCL state files in TypeScript and Python. For kubernetes users, the cdk8s project enables you to use CDK constructs for defining kubernetes configuration in TypeScript, Python, and Java. cdk8s can be used to define kubernetes infrastructure running anywhere and can be used with the AWS CDK’s Amazon Elastic Kubernetes Service (Amazon EKS) construct library. Both cdk8s and cdk tf are alpha releases.

Benefits

Easier cloud onboarding

AWS CDK accelerates your onboarding to AWS because there are few new things to learn. CDK enables you to use your existing skills and tools, and apply those to the task of building cloud infrastructure. It also provides high-level components that preconfigure cloud resources with proven defaults, helping you build on AWS without needing to be an expert.

Faster development process

AWS CDK gives you the expressive power of programming languages for defining infrastructure. Familiar features such as objects, loops, and conditions accelerate your development process. You can also use AWS CDK with your integrated development environment (IDE) to take advantage of existing productivity tools and testing frameworks.

Customizable and shareable

With AWS CDK you can design your own reusable components that meet your organization’s security, compliance, and governance requirements. Just like with any other software library, you can easily share components around your organization enabling you to rapidly bootstrap new projects with best practices by default.

No context switching

AWS CDK enables you to build your cloud application without leaving your IDE. You can write your runtime code and define your AWS resources with the same programming language. You can visualize your CDK application stacks and resources with the AWS Toolkit for VS Code.

Customers

deepwatch

deepwatch helps secure the digital economy by protecting enterprise networks, everywhere, every day. deepwatch delivers a Cloud SecOps platform managed by a team of world-class Security Experts to provide award-winning Managed Detection & Response (MDR), Vulnerability Management, and Endpoint Detection & Response Services to customers.

deepwatch is constantly innovating to best serve their clients. The engineering team at deepwatch needed the ability to develop software with a serverless-first approach, and they wanted a scalable and developer-friendly Infrastructure as Code framework to move faster. To enable this, the team chose to implement AWS Cloud Development Kit (CDK). 

“Our strict security standards are at the core of what we do. AWS CDK allows our team to provision our most common infrastructure patterns faster and more efficiently, while seamlessly integrating with our CI/CD pipelines. After making the decision to leverage AWS CDK, we migrated a very complex backend infrastructure that was fully testable and reverse engineered in less than two weeks, a 60% increase in efficiency. We will be migrating our whole IAC product suite to AWS CDK. Our goal is to be a development team that can rely on each other. CDK has greatly improved our ability to work faster and smarter as a team, supporting that goal.

Culture Amp

Culture Amp helps to make companies a better place to work by making it easy to collect, understand, and act on employee feedback. Culture Amp enables HR leaders to make better decisions, demonstrate impact, and turn company culture into a competitive edge. Using AWS, Culture Amp built the world’s first on-demand employee feedback platform back in 2012. Since then they have been supporting their fast-growing global customer base from offices in Melbourne, San Francisco, New York, and London. When Culture Amp decided to modernize their single-region monolithic application running on Amazon EC2, to a multi-region, microservices-based architecture primarily running on top of Amazon Elastic Container Service using AWS Fargate, Amazon DynamoDB, and Amazon Relational Database Service, they needed a way for engineers to consume pre-approved AWS architectures without the need to log into restricted environments or have detailed knowledge of AWS and AWS CloudFormation. The Culture Amp team turned to the AWS Cloud Development Kit (AWS CDK) to automate the provisioning of AWS Fargate services with supporting databases and user roles in a shareable and repeatable fashion. Culture Amp built a library of custom AWS CDK constructs that enabled them to programmatically create new microservices for their engineers that were feature rich and enabled increased speed and efficiency among their development teams.

"Now our engineers can consume pre-approved AWS architecture that are feature rich, including AWS Fargate services that include fine-grained deploy roles, load balancing, certificate validation, autoscaling, AWS Lambda functions to forward logs and a choice of Dynamo or RDS as a storage backend. We can now feasibly do in hours what used to take us up to six weeks”

Stedi

Stedi provides organizations with the ability to quickly connect and transact with trading partners without having to go through painful point-to-point implementations; it does this by providing a completely self-service ‘digital mailbox’ that organizations can use to exchange 300+ different commercial transaction types in standardized formats.

Stedi has an ambitious goal: help businesses save countless hours of menial tasks by processing every B2B transaction on the planet. To do this, Stedi knew it would have to offload menial tasks of its own – which is why they chose to build with a fully-serverless AWS architecture from day one. However, Stedi's work with AWS goes beyond just serverless infrastructure: they have adopted AWS-native developer tooling – like AWS CDK and AWS Amplify – to help iterate quickly and deploy frequently.

“CDK has been a gamechanger for us. It has drastically improved our feedback cycle and reduced the time it takes to go from brand-new to fully-deployed infrastructure."

Tyler van Hensbergen, Engineering - Stedi
