The Cloud Native Platform “Continuum”

Or the CNPC for short…
Unstructured Platform Structured Platform

Unstructured Platform
• A fast “on rails” development and deployment
experience
• Lower overall effort required to operate and
maintain the environment than unstructured
platforms
• Built-in capabilities and integration points for key
enterprise concerns such as user management,
security, and audit compliance Structured Platform
- Duncan Winn
Cloud Foundry: The Definitive Guide

• Built on, and adhere to, a set of well-defined
principles employing best practices
• Constrained to do the right thing for your
application, based on defined contracts
• Consistent across environments, with every
feature working as designed out of the box
• Configurable, and extendable, but not to the
extent that the nature of the platform changes Opinionated Platform
- Duncan Winn

Opinionated Platform

Opinionated Platform
“ Google actually said it really well, because they get
asked this question too: ‘Why are you excited about Cloud
Foundry and supporting that? Aren’t it and Kubernetes
competitive?;’ And they said, ‘Kubernetes is really a
technology that allows people to build a platform to run
their applications. And Pivotal Cloud Foundry is a
platform to run your applications.”
- Rob Mee
Pivotal CEO

“Cloud Foundry is an opinionated, structured
platform that rectifies PaaS confusion by
imposing a strict contract between:
• The infrastructure layer underpinning it
• The applications and services it supports”
- Duncan Winn

“Every app dies, not every app truly lives”
- Josh Ghiloni
ECS Senior Cloud Architect

What’s in a cloud native platform
• Goal to go faster – then
• Building on the foundations of containers and container orchestration,
cloud platforms add the logging, auditing, security, policies, compliance,
standard container image repo, onboarding, role-based access,
infrastructure tool abstraction,
• Platforms you hear things like docker, kubernetes
