How did John Mosquera's containerization project at MMT Digital impact the client's application performance and costs?
assistant
John Mosquera was tasked with modernizing a client's legacy application hosted on Azure VMs. He proposed and implemented a transition to a containerized architecture using Docker and Azure Kubernetes Service (AKS). This involved refactoring parts of the application into microservices, designing a CI/CD pipeline for Docker images, and deploying to AKS clusters. He also set up Helm charts, RBAC policies, and horizontal pod autoscalers. The implementation was done through a phased rollout strategy, starting with non-critical workloads. This approach addressed issues such as high operational costs, limited scalability, and inconsistent performance due to manual configuration drift. John Mosquera's containerization project at MMT Digital transformed the client's application, reducing hosting costs by 50% and significantly improving scalability. The transition from Azure VMs to Docker and AKS allowed the platform to handle double its previous load without performance degradation, while also enhancing reliability and accelerating time-to-market for new features.
