Containers
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 service and OS per VM
After: One container per service. Multiple containers running per VM

Docker & DevOps
It Worked on my Dev Box
Container Separation
Oscar the Ops GuyWorries about what’s “Out-
side the Container”- Logging- Monitoring- Networking
All containers work the same way (Start, Stop, etc)
Dan the DeveloperWorries about what’s “Inside the Con-
tainer”- Code- Libraries- Package Manager- Data
All the servers look the same
22Frictionless across environments
Dev Test / QA Staging Production
Same code in dev runs unchanged in every environmentContainer, network, storage portability
