photo by Adrian I gave a talk at Monitorama in Portland Oregon in June, which set out the idea that carbon is just another metric to monitor, and that in a few years most of the monitoring and performance tuning tools are going to be reporting and optimizing for carbon alongside latency, throughput, availability and cost.

They state in the blog that this was quick to build, which is the point. His first edition in 2015 was foundational, and he updated it in 2021 with a second edition. When you are exploring how to construct something, building a prototype in a few days or weeks is a good approach. Finally, what were they building?

Metrics are measures of critical system values, such as CPU utilization or average write latency to persistent storage. They are particularly important in distributed systems, such as microservices architectures. Observability platforms are becoming essential as the complexity of cloud-native architectures increases.

I previously wrote about Netflix in [2015] and [2016], and if you are interested in what it's like to work here, I already covered much in those posts. As before, no one at Netflix has asked me to write this, and this is my personal blog and not a company post. A latency outlier issue that happened every 15 minutes. Time flies!

Requirements In a previous blog post, we discussed Delta , a data enrichment and synchronization platform. In our Delta blog post , we also described use cases beyond data synchronization, such as event processing. DBLog High Level Architecture. High Availability DBLog uses active-passive architecture.
