Operations teams want to make sure the system doesn’t break. Keptn is an open source control plane that enables cloud-native continuous delivery and automated operations. Dynatrace has an enterprise version of Keptn as part of its cloud software-as-a-service (SaaS). Authenticates using Dynatrace single sign-on.

From May 17 to May 18, 2021, the Open-Source Engineering team at Dynatrace attended the virtual observability conference, o11yfest. To improve their alerting system, the team decided to move to SLO/SLI-based alerting, which require deeper knowledge of the application but are more helpful than generalized metric alerts.

This talk originated from my updates to Systems Performance 2nd Edition , and this was the first time I've given this talk in person! CXL in a way allows a custom memory controller to be added to a system, to increase memory capacity, bandwidth, and overall performance. Or even on a plane. It was a great privilege.

The need for systems to be resilient is still increasing, and chaos engineering tools and techniques are developing as a key way to validate that resilience is working as designed. If you are building resilient systems with failover, the control plane that manages failover is often the hardest part of the system to get right.

While it’s sadly premature to say that the survey took place at the end of the COVID-19 pandemic (though we can all hope), it took place at a time when restrictions were loosening: we were starting to go out in public, have parties, and in some cases even attend in-person conferences. Salaries were lower regardless of education or job title.

I don’t need more bandwidth for video conferences or movies, but I would like to be able to download operating system updates and other large items in seconds rather than minutes. But that’s also a problem that 5G vendors could solve; virtual LANs ( VLANs ) are hardly a new concept. We won’t need to worry about backups.

The shift to cloud native design is transforming both software architecture and infrastructure and operations. Still cloud-y, but with a possibility of migration. Strong usage in cloud platforms (+16%) accounted for most cloud-specific growth. Cloud native design is a new way of thinking about software and architecture.

This was the genesis of the Amazon Dynamo database.
