Treat your infrastructure like a piece of code and you get reproducibility, scalability, and less time spent on manual setup. To read more about IaC, check out our blog post [Understanding Infrastructure as Code (IaC)](/blog/post/understanding-infrastructure-as-code-iac). ## [Cloud Native Infrastructure on AWS](#cloud-native-infrastructure-on-aws) Cloud Native Infrastructure means designing applications specifically for the cloud. It’s about using AWS services like AWS Lambda, Amazon DynamoDB, and Amazon S3 to build applications that scale and hold up under failure. To read more about Cloud Native Infrastructure, check out our blog post [Cloud Native Infrastructure on AWS](/blog/post/cloud-native-infrastructure-on-aws). ## [Using AWS CloudFormation for IaC](#using-aws-cloudformation-for-iac) AWS CloudFormation lets you declare your infrastructure using JSON or YAML templates instead of tracking the exact order of resource creation yourself. It also handles updates and rollbacks, so your infrastructure stays consistent and easy to manage. To read more about AWS CloudFormation, check out our blog post [AWS CloudFormation for Infrastructure as Code (IaC)](/blog/post/aws-cloudformation-for-infrastructure-as-code-iac). ## [Simplifying application deployment with AWS SAM](#simplifying-application-deployment-with-aws-sam) AWS Serverless Application Model (SAM) provides a simplified way to define and deploy serverless applications on AWS Lambda. It handles the deployment details so you can focus on writing code. To read more about AWS SAM, check out our blog post [Deploying Serverless Applications with AWS SAM](/blog/post/deploying-serverless-applications-with-aws-sam). ## [Orchestrating infrastructure with Terraform](#orchestrating-infrastructure-with-terraform) Terraform is an open-source tool that lets you define and manage infrastructure as code across multiple cloud providers, including AWS, using a single workflow. To read more about Terraform, check out our blog post [Orchestrating Infrastructure with Terraform](/blog/post/orchestrating-infrastructure-with-terraform). ## [Best practices for infrastructure automation in a Cloud Native AWS environment](#best-practices-for-infrastructure-automation-in-a-cloud-native-aws-environment) The linked post below covers securing your infrastructure, implementing CI/CD pipelines, and managing cost so your setup keeps performing as it grows. To read more about best practices for infrastructure automation, check out our blog post [Best Practices for Infrastructure Automation in a Cloud Native AWS Environment](/blog/post/best-practices-for-infrastructure-automation-in-a-cloud-native-aws-environment). ## [Conclusion](#conclusion) This post covered the basics of IaC in a Cloud Native AWS environment, and how AWS CloudFormation, SAM, and Terraform each play a role. The tools handle the repetitive parts; the design decisions are still on you.
