Today @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. www.ergonautic.ly
We have a lot more automation @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
We have a lot more automation tools @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
We have much higher availability @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
We have better on-call @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
We have better incident response @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
We deploy a lot more frequently @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
BUT @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
Many of us are bad at monitoring @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
Many of us are bad at CI @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
Continuous Integration (CI) The practice of merging code into the main branch several times a day; and automating the build and testing on every commit. @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. www.ergonautic.ly

@ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. www.ergonautic.ly
We have convinced people that deploying faster is good We forgot to mention that increasing the Operational Burden is bad @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic

SRE ≃ Google’s implementation DevOps @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
Why did SRE develop? @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
SaaS Market 2008-2020 @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
What is the most important thing about the SRE discipline? @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
SRE is about explicit agreements that align incentives @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
SLA, SLI, SLO @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
SLA = Financially-backed availability @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
Monthly downtime > 1.5 days means 100% refund COPYRIGHT 2023. ALL RIGHTS RESERVED.
SLAs are about aligning incentives between Vendor & Customer COPYRIGHT 2023. ALL RIGHTS RESERVED.
SLO = Targeted reliability @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
While SLA is a single metric, SLOs are a system of metrics COPYRIGHT 2023. ALL RIGHTS RESERVED.
SLO = Business-approved reliability @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
SLOs are about explicitly aligning incentives between Business & Engineering @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
Error Budgets Acceptable level of unreliability Error budget = 1 - SLO EB = 1 – 99.99% = 0.01% ≃ 13 mins /quarter @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. www.ergonautic.ly
Error budgets are about aligning incentives between Dev & Ops @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
If developers are measured on the same SLO, then when the error budget is drained developers shift focus from delivering new features to improving @ergonauticly Reliability COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
SLI = Actual reliability @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
Monitoring @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
Without monitoring, you have no way to tell whether your service even works! @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
Good Monitoring @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic
Without good monitoring, you don’t know that the service does what users expect it to do! @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. Ergonautic

Most Organizations today ● Don’t merge code frequently ● Don’t have quality testing during CI ● Don’t have informative monitoring ● Don’t enforce Error Budgets ● Don’t have a platform @ergonauticly COPYRIGHT 2023. ALL RIGHTS RESERVED. www.ergonautic.ly

The term DevOps first appeared in 2009, and since then has been used to describe a cultural shift, an engineering job title, and many products in the Continuous Integration and Continuous Delivery space. In this session, we will talk through the brief history of DevOps as a methodology, a set of technical skills, and an umbrella of technologies, and then dive into what the next 5 to 10 years are likely to look like in the DevOps space.

can too.
