Lugano Tech Talks - Why Docker
- 2. Agenda • Introduction • Why Docker • Containers vs VM’s • Use Cases • Demo
- 3. Brian Christner Brian.Christner@swisscom.com / @idomyowntricks ● Swisscom Cloud Architect ● Background in Containers, Cloud, & Engineering ● Docker Captain
- 5. 5 The application landscape is changing Loosely Coupled Services Many Small Servers or devices ~2000 Today Monolithic Big Servers Slow changing Rapidly updated
- 6. Development VM QA Server Public Cloud Disaster Recovery Contributor’s Laptop Production Servers Production Cluster Data Center Containers are the catalyst Static Website Web Front End Background Workers User DB Analytics DB Queue API Endpoint
- 7. 7 Docker delivers innovation, speed and savings + +Agility Portability Control State of App development Survey: Q1 2016, Cornell University case study 13XMore software releases 62%Report reduction in MTTR 10XCost reduction in maintaining existing applications Eliminate “works on my machine” issues 41%Move workloads across private/public clouds 65%Reduction in developer onboarding time
- 12. Long vs Short Lived Apps/Containers Long Lived Short Lived
- 13. VM’s
- 15. Reduce Costs & Streamline Operations Containers and VMs together: • Optimize: Added flexibility in using infrastructure resources • Consolidation: Greater workload density across existing servers. • Reduce Costs: Lower OS and VM licensing CapEx and reduce OpEx costs to support and maintain smaller infrastructure Before: One application and OS per VM After: One container per service.

- 18. Container Separation Oscar the Ops Guy Worries about what’s “Outside the Container” - Logging - Monitoring - Networking All containers work the same way (Start, Stop, etc) Dan the Developer Worries about what’s “Inside the Container” - Code - Libraries - Package Manager - Data
