Server consolidation, real-time monitoring, continuous integration and deployment, docker-based virtualization etc. are some of the ways to optimize the infrastructure costs. Problem: Customer wanted to reduce the server maintenance costs and speedup the deployment process Methodology: Cenacle optimized the IT infrastructure costs by implementing the DevOps best practices as below:

1. Consolidated the servers to share the resources
2. Created Docker containers for core modules that need scaling
3. Implemented CI/CD for auto deployment
4. Implemented monitoring tools to identify and auto-scale the resources based on demand

Results: Achieved a 3 fold reduction in the server costs over a period of 6 months from USD 18k down to USD 6k Key technologies used: Kubernetes, Docker, Rancher, Elasticsearch, MongoDB, Grafana, Postgres, Nagios, Prometheus Domain: IT Infrastructure, DevOps
