Modernization Legacy Infrastructure

This case study focuses on our approach to tackling the challenges of outdated systems by leveraging cutting-edge technologies like Infrastructure as Code (IaC) and modern CI/CD pipelines. We achieved enhanced security, reduced overhead, and a more robust IT infrastructure, modernizing legacy systems for future-ready business operations.

Challenges

Outdated Infrastructure Reliance:

The startup depended on outdated Ubuntu VMs hosted on AWS, which had not received security updates for several years, posing significant security risks.

Security Risks from Legacy Systems:

The lack of timely updates made these legacy VMs a serious security liability.

Inefficiencies in Deployment:

Manual processes for deployments and updates significantly slowed application delivery and increased the maintenance burden.

Solutions

Infrastructure Assessment:

Conducted a comprehensive evaluation of the existing cloud infrastructure within AWS to identify critical vulnerabilities.

VM Upgrades:

Upgraded outdated Ubuntu VMs to newer, supported versions to mitigate security risks.

Automation with Terraform:

Implemented Terraform to enable Infrastructure-as-Code practices, automating the provisioning and management of infrastructure on AWS.

CI/CD Pipeline Implementation:

Set up an automated CI/CD pipeline using Jenkins or GitLab Actions to facilitate streamlined and consistent deployments and updates.

Results

Infrastructure Modernization:

Successfully modernized the cloud infrastructure, significantly enhancing security and scalability.

Security Enhancement:

Improved the security posture by upgrading VMs and integrating security best practices within the AWS environment.

Streamlined Application Delivery:

Automated deployments and updates have streamlined application delivery processes.

Reduced Maintenance Overhead:

Automation has reduced the maintenance overhead, allowing IT resources to be redirected towards more strategic initiatives.
