Hello • I’m Karthik Gaekwad • Head of CloudNative Engineering at Verica • https://www.verica.io/ • Chaos Engineering for Kubernetes @iteration1 @iteration1
Hello • Been in Industry 15 years. • In general, I like building stuff with friends. • Love Teaching and building community. • Run DevOpsDays Austin, Container Days, Cloud Austin. • Chair All Day Devops Cloud Native track. • LinkedIn Learning Author for Learning Kubernetes (and more). @iteration1
Quick History of Devops @iteration1
History of Devops • 2008: Agile Conference • Birds of a feather….“Agile Infrastructure” pitched by Andrew Clay Shafer. • Patrick DeBois Attended the BOF. • Andrew….didn’t. • Later on in the conference they connected to talk more about operations and development topics. @iteration1
History of Devops @iteration1
But wait, what is it really? @iteration1
“DevOps is the practice of operations and development engineers participating together in the entire service lifecycle, from design through the development process to production support.” https://theagileadmin.com/what-is-devops/ @iteration1
Pillars of Devops (CALMS) Lean Automation Culture Sharing Measurement @iteration1
At least, that was the intention… @iteration1
What has it become today? @iteration1
Pillars of Devops (CALMS) Automation Measurement Culture Lean Sharing @iteration1
Why did this happen? @iteration1
Why? • Automation/Measurement is an easier problem to solve… @iteration1
Why? • Organizational Culture is hard to quantify @iteration1
Why? • Change is hard @iteration1
Why? • Our Devops definition changed and focused on a subset of pillars. • Forgot that Devops was a people and alignment problem.. @iteration1
Por qué Devops in a box… Devops Devops @iteration1
Where do we go from here? Common Question I still get: “How do we start?” @iteration1
Where to go? •Business does not stop. •Business always wants to go faster. DORA State of Devops Report 2019
Evolution of Development and Deployment Development Process Application Architecture Deployment and Packaging Application Infrastructure Waterfall Monolithic Physical Server Datacenter Agile N-Tier Virtual Servers Hosted DevOps Microservices Containers Cloud ~ 1980 ~ 1990 ~ 2000 ~ 2010 Plan Monito r Now Code Operate Build Deply Test Release
Alignment between technical and business Alignment in the technical team @iteration1
Devops is a people problem Keep your teams working effectively. @iteration1
Devops 2.0 Current and Future Trends @iteration1
SRE •Subset of Devops •Responsible for the availability, latency, performance, efficiency, change management, monitoring, emergency response, and capacity planning of their service(s). • https://landing.google.com/sre/sre-book
Rise of Cloud Native “A new computing paradigm that is optimized for modern distributed systems environments capable of scaling to tens of thousands of self healing multi-tenant nodes” -Cloud Native Computing Foundation
Rise of Cloud Native •Based on Kubernetes and container technology •Rich landscape, big community, but complicated to navigate. @iteration1
Rise of Serverless •New Execution Model. •Cloud Provider manages your resources. •You only manage your code. @iteration1
Observability • Understanding what is going on in distributed systems. • Observability is a measure of how well internal states of a system can be inferred from knowledge of its external outputs. • Determine system behavior from system outputs. @iteration1
New Era in Testing, Security, Database • Underrepresented groups joining the shift, embrace them. • New groups joining the movement: • DevTestOps (https://testingindevops.org/) • DevSecOps (https://www.devsecops.org/) • DevDBOps @iteration1
5 Practical Takeaways @iteration1
Learn what the other side is doing Devops == Collaboration @iteration1
Understand your business They pay you $ @iteration1
Use Architecture to your advantage Helps you get back on track @iteration1
Always be learning… Or your might have to find a new job… @iteration1
