Durgesh Singh

Cloud & DevOps Engineer with expertise in AWS, OpenStack, OpenShift, Linux, Kubernetes, and CI/CD automation. Adept at designing and managing cloud infrastructure, monitoring solutions,and containerized deployments. Passionate about DevOps automation, cloud security, and site reliability engineering (SRE).

OpenStack Infrastructure Management

 Managed OpenStack infrastructure across compute, storage, and networking services,

ensuring 24/7 availability.

 Integrated monitoring tools like Grafana, Kibana, and Prometheus for 70+ Pan-India sites.

 Expanded compute, KVM, and Ceph nodes on live sites, following proper CR and incident timelines.

 Configured and monitored virtual machine (VM) health and performance using

Prometheus and custom exporters.

 Performed OpenStack upgrades and migrations with minimal downtime, ensuring seamless service continuity.

 Automated routine tasks and system upgrades to enhance operational e􀆯iciency.

 Collaborated with cross-functional teams to troubleshoot performance bottlenecks in

Nova, Neutron, and Cinder services.

 Validated MBSS documents for the H-Cloud Project while implementing security hardening concepts.

 Managed and configured backups for all sites using the Commvault backup tool.

Monitoring and Observability

 Deployed and maintained monitoring tools (Prometheus, Thanos, Grafana) for real-time observability and long-term metrics storage.

 Integrated Thanos for scalable and centralized metric queries across distributed

Prometheus instances.

 Utilized Prometheus CLI query language and Kibana to advance AI/ML use cases.

 Performed all testing and alert configuration for site expansions and new node validations.

 Created custom dashboards and set up alerts for critical infrastructure metrics.

Site Expansion Projects

 Led site expansion projects by provisioning compute and storage resources using Heat templates and manual orchestration.

 Validated and tested newly expanded nodes to ensure optimal performance and reliability.

Incident and SLA Management

 Created and resolved TTs (Trouble Tickets) and CRs (Change Requests) for all issues and activities, ensuring compliance with SLA.

 Monitored and ensured the timely delivery of health checkup reports using Python and

Linux scripting.

OpenShift and Container Management

 Managed multiple projects within OpenShift, handling resource allocation and scaling for services and pods.

 Created, updated, and deleted ConfigMaps and Secrets to manage dynamic application configurations.

 Integrated Prometheus and Grafana for real-time monitoring and improved cluster observability.

 Troubleshot pod failures and network issues, achieving 99.9% application uptime.

 Monitored pod health and resolved performance issues using OpenShift Web Console and CLI tools.

 Contributed to automation scripts for container builds, deployment rollbacks, and log collection.

Data Analytics and Reporting

 Integrated multiple network components in the NLM project using data analytics and

Excel skills on Logstash and Elasticsearch.

 Utilized advanced data analysis techniques to ensure accurate insights and system performance.
