While Google’s SRE Handbook mostly focuses on the production use case for SLIs/SLOs, Keptn is “Shifting-Left” this approach and using SLIs/SLOs to enforce Quality Gates as part of your progressive delivery process. This will enable deep monitoring of those Java,NET, Node, processes as well as your web servers.

Or worse yet, sometimes I get questions about regaining normal operations after a traffic increase caused performance destabilization. But we can discuss common bottlenecks, how to assess them, and have a better understanding as to why proactive monitoring is so important when it comes to responding to traffic growth.

Amazon ElastiCache embodies much of what makes fast data a reality for customers looking to process high volume data at incredible rates, faster than traditional databases can manage. Developers love the performance, simplicity, and in-memory capabilities of Redis, making it among the most popular NoSQL key-value stores.

They use a combination of timeouts, retries, and fallbacks to try to mitigate the effects of these failures, but these don’t get exercised as often as the happy path, so how can we be confident they’ll work as intended when called upon? If ChAP detects excessive customer impact during an experiment, the experiment is stopped immediately.

There are many possible failure modes, and each exercises a different aspect of resilience. Staff should be familiar with recovery processes and the behavior of the system when it’s working hard to mitigate failures. A resilient system continues to operate successfully in the presence of failures.

This month and the next I’m going to cover the physical processing aspects of derived tables. That is, does SQL Server perform a substitution process whereby it converts the original nested code into one query that goes directly against the base tables? And if so, is there a way to instruct SQL Server to avoid this unnesting process?

These can be useful exercises, certainly to the business leaders who’ve got to find their customers or compete against rivals with slimmed down cost structures. But the ability to study, process, absorb, investigate and prove ways of exploiting heretofore unrealizable opportunities is priceless. These are less useful.

I started with a cmd file script exercising the connection path. Running along and all the sudden no traffic occurring at the SQL Server for a few seconds, then stress kicked back in.

For example, ghost code - code that is not commented out but will conditionally never be executed - is likely to be confused for real code in a reverse-engineering exercise. A clone of something extinct - our lost business knowledge - runs the risk of suffering severe defects. The facts are fantastic to have, but facts are not knowledge.

Where other systems may take over ten minutes to process metrics accurately, Mantis reduces that from tens of minutes down to seconds, effectively reducing our Mean-Time-To-Detect. Instead, we should process and serve events one at a time as they arrive. Operational use cases are inherently time sensitive by nature.
