“Cloud native technologies empower organizations to build and run scalable
applications in modern, dynamic environments such as public, private,
and hybrid clouds. Containers, service meshes, microservices, immutable
infrastructure, and declarative APIs exemplify this approach.
These techniques enable loosely coupled systems that are resilient,
manageable, and observable. Combined with robust automation, they allow
engineers to make high-impact changes frequently and predictably
with minimal toil.”

Technical Stack Dept
“Technical debt is a concept in software development that reflects the implied
cost of additional rework caused by choosing an easy solution now instead of using
a better approach that would take longer.”

CI/CD Disappointment
“87% of attendees surveyed during Gartner conferences between 2015 and 2016
admitted that DevOps had not delivered on their expectations.”
– Simon Horrocks

Essential Question: What is your company-wide workflow?
• What have you promised to deliver your customer?
• What is the objective for each company, organization, department, team,
engineer?
• Use the objectives gathered to identify the data you need.
• Instrument for depth, not breadth.
• Codify alert states; automation is important.
