Tell about a project at Megafon: architecture, technical details, stack.

In a project for MegaFon, I participated in automating the deployment and monitoring of infrastructure.

The architecture included several microservices deployed in a Kubernetes cluster. Jenkins and GitLab CI were used for CI/CD.

Technical details:

• Automation with Ansible for server configuration
• Monitoring using Prometheus and Grafana
• Logging through the ELK stack (Elasticsearch, Logstash, Kibana)

Stack:

• Docker and Kubernetes for containerization and orchestration
• Ansible for configuration management
• Jenkins/GitLab CI for build and deployment automation
• Prometheus/Grafana for monitoring

This enabled faster releases and increased service stability.
