Containers, VMs, and Clouds: Containers & Clouds & VMs: OH - - PowerPoint PPT Presentation

Containers & Clouds & VMs: OH My

Containers, VMs, and Clouds: Oh My!

Mike Coleman, Technology Evangelist – Docker @mikegcoleman

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?

They’re different, not mutually exclusive

Just answer the question . . .

Besides, you wouldn’t like the answer

So many variables

• Performance
• Security
• Scalability
• Existing Skillsets
• Costs
• Etc.

• Capacity
• Mixed Workloads
• Latency
• Disaster Recovery
• Licensing Costs

Points to Consider

• 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

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

17

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

• pen 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

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

Cornell University

• First Dockerized App: Confluence – April

2015

• Complicated Tech Stack

− Apache 2.2.10 − OpenSSL 0.9.8H − Java 1.6 (EOL 2/13) − Confluence 5.6.5

• Custom code for SSO and LDAP

integration

• Previous Confluence update took 6

months

• Out of synch environments
• Brain drain

20

Cornell University – End Product

• Infrastructure as code
• Custom images (rebuilt daily)
• CI workflow featuring Jenkins and

Docker Trusted Registry

• Quarterly upgrades
• 2 Months to Dockerize and move

Confluence to the cloud

• 10x reduction in staff hours

supporting Confluence

“ . . . Docker can improve the state of many applications including legacy and vendor solutions”

• Shawn Bower, Cloud Architect –

Cornell University

What’s the Right Tool for the Job?

So, what’s next

• Pick a project
• Get your hands dirty
• Mistakes may (will) be made
• Join the community

Thank You! Q&A
