Slides for the breakout "Containers are not just for microservices", from DockerCon EU 2017 in Copenhagen.

1. Containerizing
Legacy Workloads
Containers
aren’t just for
microservices

CONTAINERS
ORCHESTRATION
DRIVERS
DRIVEN BY BUSINESS NEEDS FOR HIGHER SPEED, FLEXIBILITY
AND COST REDUCTIONS, ENTERPRISES ARE TURNING TO
CONTAINERS TO SUPPORT THEIR JOURNEY TO CLOUD
DEVOPS

4. THE VALUE PROPOSITION OF CONTAINERS
IS ALSO VALID FOR LEGACY WORKLOADS
SPEED TO
MARKET
Fast time to market is
not relevant only for
greenfield apps
JOURNEY TO
CLOUD
Accelerate the journey to
cloud, with containers
COMPLIANCE
Control the entire
software supply chain:
what runs where, by
whom, what is packaged
inside a container, apply
policies to control runtime
access
AGILITY PORTABILITY COST SAVINGS SECURITY

PRODUCTIVITY
• Reduce/eliminate virtualization licenses for workloads to be
containerized
• Reduce number of hardware blades/servers/cloud instances
• Faster container startup times means instances can be turned
off when not used, or dynamically scaled according to demand
• Minimize environment and configuration defects in new
environment setup by packaging all components and
dependencies in containers
• Provision an arbitrary number of application environments
easily, when needed, and destroy them when done
• Minimize human effort / involvement with deploying code to new
environments
• Containers are a great runtime platforms for modern scalable
and high performance application architectures like
Microservices-based architectures
• Greatly reduce the amount of time needed for a developer to
create a working application environment locally

8. STRUCTURING THE MIGRATION
ASSESS & QUALIFY ESTIMATE CONTAINERIZE

9. SCALING UP THE ORGANIZATION
Availability of container skills internally
INTERNAL CENTRAL
TEAM
• Migration conducted by an
internal team, staffed by
current IT resources
• Does not scale; limited
availability to support a
large number of projects
• Team may have other
priorities
MIGRATION FACTORY
• Working with projects Fast,
efficient deployment
• Shared team provides
economies of scale and
knowledge sharing
• Optimized resource model
• Focused on migration
delivery and managed to
avoid cost overruns
PROJECT-BASED
• Leverage existing project
teams to orchestrate and
execute migration effort
• Limited cross-team
knowledge sharing
• Lengthier migration
• Inconsistent migrations

CONTAINERS CAN SIMPLIFY APPLICATION
ARCHITECTURE
One big fat application server/middleware Multiple smaller, independent containers
Configuration files Secrets management
Specific hardware
Multi-tenant hosts (typically) with a resource
scheduler and a declarative resource definition
(Compose)
Complex clustering and custom load balancing UCP handles fault tolerance, built-in load
balancer for TCP and HTTP traffic
Complex scaling Easily scale the number of containers

CONTAINERS ENABLE LEGACY APPLICATIONS
INTO A DEVOPS-ENABLED WORLD
BUILD TEST
PUSH
CONTAINER
DEPLOY
• Sometimes, legacy applications barely have any build
automation
• Running tests in/with containers greatly simplifies the QA
process, but some scripting will be required

OPERATIONAL PROCESSES CHANGE WHEN
RUNNING IN A CONTAINERIZED ENVIRONMENT
LOGGING
MONITORING
RUNBOOKS
Container logs must be collected and made available to application
teams, typically using a log aggregation tool
Container-native monitoring tools greatly simplify the process of
monitoring containers – no one wants to run agents in each container
Starting and stopping an application, scaling, troubleshooting, are
fundamentally different in containers – runbooks and guides need to be
updated accordingly
ORGANIZATIONContainers – are they infra, application, neither, or both?
