Deploying a Secure Multi-Tenant AWS Infrastructure with Terraform and AWS CodeCommit: A DevOps HumanGov Project

HumanGov: Deployment Of A Reusable SaaS Multi-tenant AWS Infrastructure Using Terraform Modules Securely Storing Terraform Configuration Files On AWS Code Commit.

Introduction

In DevOps, the ability to efficiently deploy and manage infrastructure is paramount. For our recent DevOps project at HumanGov, we embarked on a journey to deploy a reusable SaaS multi-tenant AWS infrastructure using Terraform modules, all while ensuring the secure storage of Terraform configuration files through AWS CodeCommit. This blog post will take you through the critical aspects of our project, highlighting the use of AWS services such as EC2 instances, DynamoDB databases, and S3 buckets.

The Challenge

The primary challenge was to create over ten EC2 instances, each residing within its isolated tenant environment, complete with its dedicated Virtual Private Cloud (VPC), S3 bucket, and DynamoDB database. This task may sound daunting, but thanks to Terraform’s powerful variable system, I could streamline the process and avoid the need for manual naming and duplication of modules.

Leveraging Terraform Variables

Terraform variables played a pivotal role in simplifying our infrastructure deployment. Utilising variables eliminated the need to duplicate configurations for each tenant, making the process far more efficient and less error-prone. This allowed me to dynamically create and manage resources for each tenant, ensuring scalability and consistency across the board.

Secure Configuration Storage with AWS CodeCommit

To ensure the secure storage of our Terraform configuration files, I turned to AWS CodeCommit. This powerful version control service facilitated collaboration and provided a secure repository for our infrastructure-as-code (IaC) files. With AWS CodeCommit, we could confidently manage and version my Terraform codebase, keeping it safe from unauthorised access or accidental changes.

Seamless Integration with AWS

One of the remarkable aspects of this project was the seamless integration with AWS services. The entire process was straightforward since my customer’s requirements were confined to the AWS environment. I remained within the secure boundaries of AWS, never venturing into the territory of public cloud providers. This choice ensured that my infrastructure remained robust and aligned with industry best practices for security and compliance.

Conclusion

In conclusion, this DevOps project at HumanGov demonstrated the power of Terraform and AWS services inefficiently deploying and managing a multi-tenant AWS infrastructure. I achieved a scalable and secure solution by harnessing the flexibility of Terraform variables and safeguarding our Terraform configurations with AWS CodeCommit. Moreover, the clients commitment to the AWS environment ensured that this infrastructure remained reliable and complied with stringent security standards.

As the world of DevOps continues to evolve, projects like these showcase the importance of leveraging automation, infrastructure as code, and cloud-native solutions to meet the demands of modern IT environments.
