Three key points about the document: 1. It discusses the concept of a cloud native platform continuum, with unstructured platforms on one end and opinionated structured platforms like Cloud Foundry and Pivotal Cloud Foundry on the other. 2. It explains the various contracts and layers that make up a cloud native platform like Pivotal Cloud Foundry, including the contracts between the infrastructure, BOSH, Cloud Foundry, services, applications, and developers. 3. It provides an overview of how Pivotal Cloud Foundry is distributed across availability zones and cells, and how developers can use the cf CLI to push applications which then get deployed through an auction process.

29. The Cloud Native Platform “Continuum”

30. Or the CNPC for short…
The Cloud Native Platform “Continuum”
Unstructured Platform Structured Platform

31. 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
Or the CNPC for short…
The Cloud Native Platform “Continuum”
- Duncan Winn
Cloud Foundry: The Definitive Guide

32. Unstructured Platform Structured Platform
• 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
Or the CNPC for short…

35. Unstructured Platform Structured 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
Or the CNPC for short…
The Cloud Native Platform “Continuum”

36. “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

70. Questions?

72. 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
