The document presents a discussion on the differences and synergies between containers, virtual machines (VMs), and cloud technologies, emphasizing their respective functionalities and how they can be used together. It highlights the benefits of containers, such as improved deployment times, reduced costs, and flexibility in resource management, while also addressing challenges faced in software development and deployment. The author encourages engagement with the technology community to learn and adopt best practices in utilizing these infrastructure technologies.
Containers and VMs and Clouds: Oh My. by Mike Coleman
- 1. Containers & Clouds & VMs: OH My Mike Coleman Technology Evangelist @mikegcoleman
- 2. 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)
- 3. So why are you sitting here today • Containers vs. VMs? • Physical vs Virtual? • Virtual vs. Cloud? • Cloud vs. Physical?
- 4. VMs 4
- 5. Containers 5
- 6. They’re different, not mutually exclusive 6
- 7. Just answer the question . . .
- 8. Besides, you won’t like the answer http://nextgenerationgardener.blogspot.com/2013/03/building-show-garden-gathering-it-all.html
- 9. So many variables • Performance • Security • Scalability • Existing Skillsets • Costs • Etc. http://people-equation.com/do-your-words-encourage-or-deflate/math-equation_chalkboard/
- 10. Points to Ponder, People • Capacity • Mixed Workloads • Latency • Disaster Recovery • Licensing Costs • Existing Automation Frameworks • Resource Pools / Quotas • Multi-tenancy
- 11. Why even start? • Faster deploy times – Build vs. Run time • Simplified dependencies • Unified tool chain • Identical environments • API automation
- 12. 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 12 Before: One service and OS per VM After: One container per service. Multiple containers running per VM Virtualization Bins/Libs App OS Bins/Libs App OS Bins/Libs App OS Virtualization Bins/Libs App OS Virtualization OS Bins/Libs App Docker Engine Bins/Libs App Bins/Libs App Bins/Libs App
- 13. 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 13 Bins/Libs App OS Bins/Libs App OS Bins/Libs App OS Bins/Libs App Bins/Libs App Bins/Libs App OS Docker Engine OS Docker Engine

- 15. ING delivers value faster Challenge • 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
- 16. Gilt deploys over 100X a day Challenge • 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
- 17. 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
