Rootconf Delhi edition

Strategies to achieve high uptime at scale. The points this talk is going to cover are:

1. A real-life case study
2. Cloud Architecture
3. Immutable infrastructure
4. Infrastructure as code
5. Secrets Management
6. Service Discovery
7. Container management and scheduling
8. Blue Green Deployment
9. Observability
