What were the key technical improvements implemented by John Mosquera during the transition from Azure VMs to AKS?
assistant
John conducted a thorough assessment of the client's existing infrastructure, identifying bottlenecks and dependencies that could impact the migration. He then implemented a containerized architecture using Docker and AKS, refactoring parts of the monolithic application into microservices where applicable. He designed and deployed a CI/CD pipeline for building Docker images and managing AKS deployments using Helm charts. Security was enhanced through role-based access control (RBAC), and autoscaling capabilities were introduced via horizontal pod autoscalers (HPA). Additionally, he integrated Datadog agents into the containers to enable real-time monitoring and observability. John Mosquera introduced key improvements such as microservices adoption, CI/CD automation, Kubernetes RBAC policies, and real-time monitoring, which collectively enhanced security, scalability, and deployment consistency.
