Mike Coleman discusses the differences between Docker containers and virtual machines, highlighting their distinct architectures and benefits. He emphasizes the importance of container security, performance, scalability, and leveraging existing skillsets while modernizing applications. The document also outlines steps for implementing container technology and encourages hands-on experience with Docker.

1. Docker?!?!
But, I’m a SysAdmin!

2. 1st half of my career was in IT Networking admin (Intel, HP)
2nd half of my career has been in product management marketing
for Docker, Puppet, VMware, and Microsoft.
Definitely more IT pro than developer

Who Am I?

3. Docker containers are NOT VMs
• Easy connection to make
• Fundamentally different architectures
• Fundamentally different benefits

4. Containers are Not VMs?
VMs Containers

5. They’re different, not mutually exclusive

6. Variables to Consider
! Performance
! Scalability
! Costs
! Security
! Existing Skillsets
! Etc.

9. Security is not just isolation
• Where did those images come from?
• Are they up to date?
• Who can access your resources?
• How do I deal with sensitive data / passwords?
• Are you communication channels secure
What is Container Security

10. Usable
Security
Secure defaults with tooling that is native to both dev
and ops

The Key Components of Container Security
Infrastructure
Independent
Trusted
Delivery
Safer Apps
Everything needed for a full functioning app is delivered
safely and guaranteed to not be tampered with
All of these things in your system are in the app
platform and can move across infrastructure without
disrupting the app

11. Usable
Security
Integrated Security with Docker Datacenter

• Developers
• Docker for Mac
• Docker for Windows
• Native Linux
• Ops
• Docker for AWS
• Docker for Azure
Leveraging Existing Skillsets

13. Docker For AWS

14. One platform and one journey for all applications
1 Traditional apps in containers
Gain portability, efficiency and security

Transform to Microservices
Look for shared services to transform
Accelerate New Applications
Greenfield innovation

15. Modernize Traditional Apps
Existing
Application
Modern
Methodologies
Integrate to CI/CD
and automation

Convert to a
container
with Docker EE
Modern
Infrastructure
Built on premise, in the
cloud, or as part of a
hybrid environment.
Modern
Microservices
Add new services or

16. Modernizing a Traditional Application
Demo

17. • Involve all the people
• Dev
• Ops
• Security
• Exec
• Perf
• Choose the right partners
• Define your guardrails
• You will make mistakes, be flexible
• Sweat the small stuff
Key Customer Cultural Learnings

18. • Start small
• MTA or Microservices: Your call
• What’s your plan for:
• Static port mappings
• Per environment configs
• Persistent data
• Adapt your processes
Picking the right Project

19. Thank You
What to do next:
• Test drive the tech at our hands on labs
• Great customer sessions
• Pick a pilot project, and get your hands dirty
• Share your knowledge and your missteps
