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
