THEMES IN IT TODAY

DEVOPS AND CLOUDSeismic shift in how organizations work with IT

OPERATIONAL AGILITYAutomation is required for both DevOps and Cloud

DEFINE ONCE, RUN ANYWHEREAutomation improves cloud-posture and technology adoption

BINGO

CLOUDAKA HPC two decades ago.

DEVOPSYou can’t buy it. But good tools help.

INTERNET OF THINGSSo wait. My servers aren’t things?

SERVERLESSIt’s really just a name. Or Hosted PaaS?

WEB 2.0Your fax machine is calling...

HIGH AVAILABILITYIt depends on who you are.

DEVOPSWhat is is… and what it’s not.

COLLABORATIVEComplete end-to-end application lifecycle management

COHESIVE (COMBINES FUNCTIONS In Theory)Development, QA, Security, and IT operations all working together

FORWARD-LOOKINGTypically applied to greenfield environments(but that’s not where your pain is, right?)

DEVOPS IN TRADITIONAL ENVIRONMENTS CAN BE HARD

THE LANGUAGE OF ENTERPRISE IT

Ansible is the first automation language that can be read and written across IT.

Ansible is the only automation engine that can automate the entire application lifecycle and continuous delivery pipeline.

From development… …to production.

IMPROVE COLLABORATIONConsumers of servers have clear method to define and request changes

PROMOTE ADOPTIONAutomation doesn’t remove responsibility from concerned teams

GETTING STARTED

Automation, automation, automationLCD is not always a bad thingProcess is the securityUnify current build processEnable auto-application of updates through CI/CD on OS layer
