Performance Evaluation of Container Runtimes
The co-location of containers on the same host leads to significant performance concerns in the multi-tenant environment such as the cloud. These concerns are raised due to an attempt to maximize host resource utiliza- tion by increasing the number of containers running on the same host. The selection of a container runtime becomes critical in the case of strict performance requirements. In the scope of the study, two commonly used runtimes were evaluated: containerd (industry standard) and CRI-O (reference implementation of the CRI) on two different Open Container Initiative (OCI) runtimes: runc (default for most container runtimes) and gVisor (highly secure alternative to runc). Evaluation aspects of container runtimes include the performance of running containers, the performance of container runtime operations, and scalability. A tool called Touch- Stone was developed to address these evaluation aspects. The tool uses the CRI standard and is pluggable into any Kubernetes-compatible container runtime. Performance results demonstrate the better performance of containerd in terms of CPU usage, memory latency and scalability aspects, whereas file system operations (in particular, write operations) are performed more efficiently by CRI-O.4 195

24 лютого мільйони з нас зробили вибір: не білий прапор, а синьо-жовтий стяг. Не втеча, а зустріч. Зустріч ворога. Опір і боротьба.
Це був рік болю, жалю, віри та єдності. І це рік нашої з вами незламності. Знаємо, що це буде роком нашої з вами перемоги!

On February 24, millions of us made a choice. Not a white flag, but a blue and yellow flag. Not fleeing, but facing. Facing the enemy. Resistance and struggle.
It was a year of pain, sorrow, faith and unity. And this is a year of our invincibility. We know that this will be the year of our victory!

Сьогодні вся країна вшановує памʼять Героїв Небесної Сотні.
Це нагадування про високу ціну нашої свободи і про цінності, за які ми воюємо.
Тоді, на зламі 2013-2014-го, українці зробили свій цивілізаційний вибір.
Прямо з Майдану тисячі добровольців одразу пішли на фронт. З 24 лютого 2022-го цей фронт розтягнувся на понад 3000 км. Але нас це не злякало. Ми продовжуємо боротьбу.
І ми переможемо.

Ok, folks. Now, it's my time to post a recap from Fosdem and Configuration Management Camp conferences.
You can find it on Substack or in my blog.
Also, I would appreciate it if you subscribe to my substack! I consider moving my writing activities there and keep the blog only as a markdown backup.
Unfortunately, I don't write that often, but hey, it's free to subscribe!

Monitoring benchmark: how to generate 100 million samples/s of production-like data
While the fact that VictoriaMetrics can handle data ingestion rate at 100 million samples per second for one billion of active time series is newsworthy on its own, the benchmark tool used to generate that kind of load is usually overlooked. This blog post explains the challenges of scaling the prometheus-benchmark tool for generating such a load.
