Tech Debt Correction Projects

Goals: Upgrade outdated Linux distributions to supported versions to ensure security compliance.

Challenges: Avoiding service disruption during the upgrade process and ensuring compatibility with existing applications.

Solutions: Developed an upgrade schedule, created backups, and updated each server to current versions, ensuring compatibility testing throughout.

Outcome: Enhanced system security and compliance, reducing vulnerabilities associated with unsupported software.

Goals: Resolve SSH-related vulnerabilities highlighted in security scans and enhance access security.

Challenges: Balancing secure SSH configurations with system accessibility and user requirements.

Solutions: Upgraded SSH to the latest version, implemented stronger encryption algorithms, and configured best practices for SSH keys and access restrictions.

Outcome: Improved security for SSH connections and reduced vulnerability count by 40% following the scan.

Goals: Migrate legacy applications from bare metal servers to a cloud environment for enhanced scalability and reduced hardware costs.

Challenges: Preserving data integrity and minimizing downtime during the migration process.

Solutions: Virtualized bare metal servers with Proxmox, then used Direct Connect to migrate applications to AWS EC2 with minimal downtime.

Outcome: Reduced operating costs and enabled higher scalability and availability for legacy applications.

Goals: Address high and medium-level vulnerabilities identified during regular security scans.

Challenges: Prioritizing critical vulnerabilities and coordinating patching without affecting uptime.

Solutions: Developed a patching and mitigation plan, prioritized critical vulnerabilities, and applied patches and configuration changes to reduce exposure.

Outcome: Reduced vulnerability count by 75%, enhancing system security and compliance.

Goals: Modernize legacy applications by containerizing them to simplify deployment and scalability.

Challenges: Adapting legacy applications to a containerized environment and maintaining compatibility with external systems.

Solutions: Refactored application dependencies, containerized them with Docker, and managed deployment on Kubernetes for high availability.

Outcome: Improved application scalability, streamlined deployment, and reduced infrastructure costs.

Goals: Transition legacy virtual machines from on-premises VMware infrastructure to Azure for greater scalability and disaster recovery.

Challenges: Ensuring data security and maintaining performance during the migration process.

Solutions: Established a secure VPN connection to Azure, performed staged migrations, and verified functionality post-migration to ensure reliability.

Outcome: Enhanced system resilience and reduced infrastructure overhead by 30%.
