Containers & Clouds & VMs: OH My

Who Am I?• Technology evangelist at Docker• Former: Puppet, VMware, MSFT, Intel, and HP• First half of my career was in IT• Second half in product management and
technical marketing• @mikegcoleman (but mostly soccer)
So why are you sitting here today• Containers vs. VMs?• Physical vs Virtual?• Virtual vs. Cloud?• Cloud vs. Physical?
VMs

Containers
5
They’re different, not mutually exclusive

Just answer the question . . .
Besides, you won’t like the answer

So many variables• Performance• Security• Scalability• Existing Skillsets• Costs• Etc.

Points to Ponder, People• Capacity• Mixed Workloads• Latency• Disaster Recovery• Licensing Costs
• Existing Automation Frameworks
• Resource Pools / Quotas• Multi-tenancy
Why even start?• Faster deploy times
– Build vs. Run time• Simplified dependencies• Unified tool chain• Identical environments• API automation
Reduce costs and 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

Migrate any workload anywhere
Infrastructure agnostic platform• Standardize: Docker abstracts away
the infrastructure and virtualization away from the standardized app containers
• Portability: Containers move without friction from one environment to another – no recoding needed
• Lift and Shift: Containerize legacy and microservices to gain portability

Trusted Registry
ING delivers value fasterChallenge• 9+ months to deploy to production• Poorly rated applications• Redundant processes and apps
Solution• Continuous Integration with Docker Engine and Registry open
source and adopt DevOps
Benefits • Ready to deploy in 15 minute• 1,500 deployments per week• 180 DevOps teams • CD pipeline transformed in 4 month
15
Gilt deploys over 100X a dayChallenge• From dev-to-deploy: weeks• 7 Monolithic apps• Wasted time implementing monolithic IaaS and PaaS
Solution• Continuous Delivery with Docker Engine open source and private repos on
Docker Hub
Benefits • From dev-to-deploy in minutes• 400+ microservices• 100+ innovations a day• Easily burst to cloud burst at peak shopping times
16
Dockerizing Monoliths• Microservices to Monoliths continuum• Monoliths and Microliths• Focus on the real challenges
– static configs, fixed ports, multiple processes• Start somewhere . . . • End up somewhere else
