Join Mirko Novakovic, Co-founder and CEO of Instana and Hannes Lenke, CEO of Checkly as they discuss the Reliability (R)evolution. Hear how freeing DevOps teams from complexity, empowers them to scale and accelerate with end-to-end testing and monitoring. Testing and monitoring was previously seen as slow, flaky, and costly, but this is no longer the case. Technologies like Headless, Puppeteer, and Jamstack are changing the way we ensure reliability. Combined with the ability to integrate APM into testing, you can also monitor the transactions simulated. This enables DevOps teams to push into production quicker with more reliability.

3. "DevOps is a set of practices that combines software development (Dev)
and IT operations (Ops). It aims to shorten the systems development life
cycle and provide continuous delivery with high software quality."
[https://en.wikipedia.org/wiki/DevOps]
What is DevOps?
1. Cross functional teams Dev & IT  Development focused
teams are responsible develop, build, test and run
software.
2. “...with high software quality”

4. “There is a direct correlation
between speed, stability, and
software development success.”
Google’s “State of DevOps” report

5. Measuring DevOps Performance

6. Availability plays a
major role in
DevOps success
As a result Google
is adding
availability as a
metric.
The role of availability

7. Automation

8. The traditional way

9. 1. ‘Our (Selenium, other) tests are slow.’
2. ‘We are fighting with flaky tests and need to start with our
test-suite all over again.’
3. ‘Our staging system or test infrastructure is not scalable
enough to process all of our tests in parallel.’
Why? Slow, flaky, and unreliable

10. 1 Headless browsers (cheaper & faster)
2 Modern JS-based frameworks like Puppeteer, Playwright
and Cypress (more reliable)
3 Layer-2 cloud e.g. Jamstack movement. (staging systems at
scale without any effort)
Technology change

11. “If my high level tests are fast, reliable, and cheap to
modify - then lower-level tests aren't needed.”

Impact

12. Testing Pyramid - what’s next?
UI and Service level tests are up to 20x faster!

13. 1. A scheduled E2E-test is by definition a synthetic monitoring
check!
2. Cheap, fast, and reliable - automated scripts allow constant
production monitoring testing.
3. This enables cross functional DevOps teams to ship stable
software software fast: Being an Elite team.
Wait a sec… why testing? Aren’t we
talking monitoring?
