DevOps, !microservices,!& the new !composable enterprise

Donnie Berkholz!@dberkholz

What in the world !is DevOps, anyhow?

Agile, truly tip to tail Business to customer

Tear down all the silos

“Infrastructure as code”

#monitoringsucks/#monitoringlove

Organizations with high performing DevOps organizations were 2x more likely to exceed profitability, market share and productivity

goals…!!!!!

Who Is Doing DevOps? § Google, Amazon, Netflix, Etsy, Spotify, Twitter, Facebook … § CSC, IBM, CA, SAP, HP, Microsoft, Red Hat … § GE Capital, Nationwide, BNP Paribas, BNY Mellon, !

World Bank, Paychex, Intuit … §  The Gap, Nordstrom, Macy’s, Williams-Sonoma, Target … § General Motors, Northrop Grumman, LEGO, Bosche … § UK Government, US Department of Homeland Security … § Kansas State University…

Who else?

Test your infrastructure like your code

The composable enterprise! and the Yegge memo

Containerization

Stack Overflow container traction

Microservices (not monoliths)

Separation of (business) concerns into services accessed via REST APIs

Resilient to failure, easily reusable, etc

Platform as a Service (PaaS)

Has its time finally arrived?

New Architectural Constraints

•  Pivotal CF optimizes for 12 Factor Linux applications


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


New Architectural Constraints

•  Pivotal CF optimizes for 12 Factor Linux applications •  Microservices: a radical departure from traditional

monolithic applications •  In both cases, the enterprise is

forced to “think different.”

Paying for your lunch…

•  Significant Operations Overhead •  Substantial DevOps Skills Required •  Implicit Interfaces • Duplication of Effort • Distributed System Complexity • Asynchronicity is Difficult! •  Testability Challenges


You must be this tall to use Microservices…

•  RAPID PROVISIONING •  BASIC MONITORING •  RAPID APPLICATION

DEPLOYMENT •  DEVOPS CULTURE

Architecture is abstract until it is operationalized.

Architectures that aren’t operationalized exist only on whiteboards.
