It's an exciting time for developments in computer performance, not just for the BPF technology (which I often [write about]) but also for processors with 3D stacking and cloud vendor CPUs (e.g., Ford, et al., “TCP on Upcoming Sapphire Rapids CPUs,” [link] Oct 2020 - [Liu 20] Linda Liu, “Samsung QVO vs EVO vs PRO: What’s the Difference?

The phrase “serverless computing” appears contradictory at first, but for years now, successful companies have understood the benefit of using serverless technologies to streamline operations and reduce costs. When an application is triggered, it can cause latency as the application starts. Dynatrace news.

As organizations grapple with mounting cloud complexity, IT teams know they must identify and respond to evolving issues across the entire technology stack—from mainframes to multicloud environments. Endpoints include on-premises servers, Kubernetes infrastructure, cloud-hosted infrastructure and services, and open-source technologies.

The new AWS Africa (Cape Town) Region will have three Availability Zones and provide lower latency to end users across Sub-Saharan Africa. AWS has been an active member of the local technology community since 2004. Hyrax has developed an AWS based technology called Exatype, which rapidly and accurately tests HIV drug resistance.

For example, when monitoring a database, you’ll want to know about any latency when writing data to a disk or average query response time. It also provides paths to remediation to keep the technology users rely on functioning smoothly. Experienced database administrators learn to spot patterns that can lead to common problems.

Metrics are measures of critical system values, such as CPU utilization or average write latency to persistent storage. For observability that scales with cloud-native technologies, organizations need an AI-driven observability platform like Dynatrace. Observability is made up of three key pillars: metrics, logs, and traces.

Although some vendors have added support for APIs and cloud services most have not even bothered to adapt with changing technology landscape.

Here's some output from my zfsdist tool, in bcc/BPF, which measures ZFS latency as a histogram on Linux: # zfsdist. Tracing ZFS operation latency. And namespaces, used for Linux containers, are also a relevant technology. Hit Ctrl-C to end. ^C I also checked a task list from /sys/fs/cgroup, and saw it's in a docker cgroup.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms.
