DevOps (a clipped compound of "software DEVelopment" and "information technology OPerationS") is a term used to refer to a set of practices that emphasize the collaboration and communication of both software developers and information technology (IT) professionals while automating the process of software delivery and infrastructure changes.[1][2] It aims at establishing a culture and environment where building, testing, and releasing software can happen rapidly, frequently, and more reliably

The Agile Admin

DevOps is a term for a group of concepts that, while not all new, have catalyzed into a movement and are rapidly spreading throughout the technical community. Like any new and popular term, people have somewhat confused and sometimes contradictory impressions of what it is. Here’s my take on how DevOps can be usefully defined; I propose this definition as a standard framework to more clearly discuss the various issues DevOps covers. Like “Quality” or “Agile,” DevOps is a large enough concept that it requires some nuance to fully understand

DevOps is the combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity: evolving and improving products at a faster pace than organizations using traditional software development and infrastructure management processes. This speed enables organizations to better serve their customers and compete more effectively in the market.

What even is Operability?


A technical value

14

“Software delivers little to no value unless it is deployed and running in production, with real users using it. We therefore need to understand how the production environments work, what monitoring is in place and how our software is deployed to production. By understanding the existing processes for monitoring and maintaining software in production, we can ensure that we deliver value to our customers and avoid problems at what is traditionally the most stressful time of a project”


Requirements

16

Ensuring the requirements for:

- Infrastructure- Configuration- Security- Monitoring- Alerting- Anomaly Detection- Failover Testing

Are treated the same as functional requirements:- Backlog- Clearly defined Epics & Stories- Acceptance Criteria


Infrastructure

17

Automated & Testing for:

- All pre-production environments (dev, test, qa, stage)- Production

Driven by- Infrastructure as Code- Configuration Management- Telemetry systems

For both:- Applications- Platform Capabilities


Telemetry

19

Creating software that automatically emits data:

- Monitoring- Alerting- Time series metrics- Graphing- Application logs- Business metrics- Anomaly Detection

These should be available to developers on their first deploy!


Deployment Health

20

A deployment pipeline is important

So is its health

- Automated Smoke tests for every deployment- Health endpoints that share lots of perf details-


Shared On Call

21

Feature teams should support live services:

- Everyone shares on call- Well defined runbooks- Clear escalation paths- 3rd party communications- Conference bridges


Post Mortems

22

Production will always have problems so:

- Safe environments to discuss issues- Blameless post-mortems- Root Cause Analysis (5 Why’s, timeline, fish skeleton, etc)

Continuous Delivery improves your time to market


Systems are in a constant state of failure, our thinking should reflect that
