How did John Mosquera's containerization project at MMT impact the client's operational costs, and what technologies were implemented to achieve this?
assistant
John Mosquera was tasked with modernizing a client's legacy application that was hosted on Azure Virtual Machines. The client faced high operational costs, limited scalability during peak trading hours, and inconsistent performance due to configuration drift. To address these issues, John implemented a containerized architecture using Docker and Azure Kubernetes Service (AKS). He refactored parts of the application into microservices, created a CI/CD pipeline for building Docker images and deploying them to AKS clusters, and implemented horizontal pod autoscalers to handle traffic spikes. Through optimized resource allocation and reduced licensing fees, this transition from VMs to containers running on AKS resulted in a 50% reduction in hosting costs. John Mosquera's implementation of Docker and Azure Kubernetes Service (AKS) resulted in a remarkable 50% reduction in the client's hosting costs. By transitioning from Azure VMs to a containerized architecture, he optimized resource allocation and reduced licensing fees, effectively addressing one of the client's critical pain points while introducing modern deployment practices.
