What is devops

What is DevOps? - In Simple English - Rackspace https://www.youtube.com/watch?v=_I94-tJlovg DevOps integrates developers and operation teams in order to improve collaboration and productivity by automating infrastructure, workflows, and continuously monitoring.

code small chunks - test, integrate, monitor, quickly/frequently improves ability to respond, time to market, and more focus to improving the business

how do we get an idea (feature, requirement, bug fix, enhancement) out to the customer/production. feedback - meeting expectation, how to plan/prioritize, improving process

In broad terms, DevOps is an approach based on lean and agile principles in which business owners and the development, operations, and quality assurance departments collaborate to deliver software in a continuous manner that enables the business to more quickly seize market opportunities and reduce the time to include customer feedback.

DevOps as a business-driven software delivery approach — an approach that takes a new or enhanced business capability from an idea all the way to production, providing business value to customers in an efficient manner and capturing feedback as customers engage with the capability. To do this, you need participation from stakeholders beyond just the development and operations teams. A true DevOps approach includes lines of business, practitioners, executives, partners, suppliers, and so on.

Buisness

  • Systems of record (audit/track)
  • Systems of engagement (communication) Value Enhanced customer experience ✓ Increased capacity to innovate ✓ Faster time to value How Develop and test against production-like systems ✓ Deploy with repeatable, reliable processes ✓ Monitor and validate operational quality ✓ Amplify feedback loops

CI Early/Fequent and Offten vs waiting until the end

discover issues earlier/sooner isolate/localize issues - fix defect vs attempt to reproduce and hunt for issue.

Collaborative development, generally among teams but practices can be applied to personal projects.
