• Easy to Deploy
• Modularity Dependent Upon Language / Frameworks
• Change Cycles Tightly Coupled / Obstacle to Frequent Deploys
• Inefficient Scaling
• Can Be Intimidating to New Developers
• Obstacle to Scaling Development
• Requires Long-Term Commitment to Technical Stack

• Modularity Based on Component Services
• Change Cycles Decoupled / Enable Frequent Deploys
• Efficient Scaling
• Individual Components Less Intimidating to New Developers
• Enables Scaling of Development
• Eliminates Long-Term Commitment to Technical Stack

• Are you using licensed components?
• Why are these ports open?
• Why does it need so much resource?
• This doesn’t seem very secure to me ……
• How do I scale this?
• Someone else already built a container with
this config!
• If you’ve just changed the app, why am I
getting a whole new container?

• Just relying on Containers
has only shifted the burden
of environment management
from Ops to development
• The code cannot be
delivered in an agile and
consistent fashion - there is
no single code base

Twelve Factors
• One Codebase/Many
Deploys
• Explicit Isolated
Dependencies
• Config via Environment
• Attached Backing Services
• Separate Build/Release/Run
• Stateless Processes
• Export Services via Port
Bindings
• Scale Out via Processes
• Disposable Instances
• Dev/Prod Parity
• Logs == Event Streams
• Admin Tasks == Processes

libraries and middleware
• Microservice design changes
are automatically adjusted for
