Continuous Delivery and Automated Operations on k8s with keptn
- 1. What is Andreas Grabner, Dynatrace @grabnerandi @keptnProject https://keptn.sh https://github.com/keptn
- 2. Confidential 2 That is why we are building Because cloud native delivery and operations is a BIG challenge for enterprises! Cloud Native
- 3. Confidential 3 MTTI Mean Time to Innovation MTTR Mean Time to Remediate 4.8 days 4 hours ~ 10min 12.5 days 2 days ~ 1 hour The reality and evidence supports it! https://dynatrace.ai/acsurvey Only < 5% is „Cloud Native“
- 4. Confidential 4 Quote: “Pipelines seem to be becoming our new future un-managable legacy code!“ First: solves the Continuous Delivery Problem!
- 5. Confidential 5 Quote: “We spend more time in manual communicaton than remediating issues“ Second: has Continuous Operations at its Core! ENGAGE TRIAGE FIND & ASSEMBLE RESOLVE RESTORE MANUAL COMMUNICATION MANUAL COMM Before After RESTORERESOLVE NUMBER OF ISSUES CURRENT STATE: mostly manual DESIRED STATE: mostly automated
- 6. 6 To Sum Up: Why we are building Keptn Continuous Delivery - and even more Continuous Operations - is an area where many enterprise struggle to implement proper solutions. Many approaches today are brittle, error-prone and hard to maintain Most approaches today

Notes de l'éditeur
- We did a survey with most of our attendees at PERFORM 2019 in Las Vegas – asking them questions around their cloud native projects. Please take the URL and do the survey as well! I looked at two metrics that tell me how mature an organization is: MTTI: how long does it take to get a newly built and already tested feature from pre-prod into production? 1 hour was the benchmark that our CTO gave us internally! MTTR: how long does it take to remediate any problems that may come up? This should be in the range of minutes, not hours or days! The shocking truth of this survey was that only 5% of our customers are reaping the benefits of new technology. The majority is in the bottom left half where they would have assumed that new technology gets them to the top right „magic quadrant“
- Many teams we spoken with build their own Deployment Pipelines: Combination of OpenSource & Commercial Tools for Deployment Automation! Testing Pipelines: Combination of OpenSource & Commerical Tools for Test Execution Quality Gates: Most often done manual. Some are investing in automated validation! Auto Remediation: Mostly done manual with a trend towards simply remediation actions
