To address scalability challenges, we adopted horizontal scaling, containerization using Docker and Swarm, and virtualization of servers. The introduction of DevOps tools like Ansible and Terraform helped convert the system to Infrastructure as Code, enabling easier management and scalability. We identified and implemented high-level improvements, such as job scheduling, cache optimization, and communication protocol enhancements, to overcome architectural limitations and improve system performance.
Through large-scale disaster recovery tests, we ensured business continuity by removing single points of failure. This experience led us to develop services that assist clients in preparing recovery plans and scaling their systems to the cloud. Our holistic approach encompasses technology, people, process, and product to create migration plans, perform performance audits, and reduce tech debt.
