Long holidays are ahead, which means that there will be time to return to bookmarks in Read later or re-read important articles of the outgoing year. In this post, we have collected and prepared for you a list of the most interesting materials from our blog for 2019 and we hope that they will be useful to you.
The past year has been interesting and eventful: new technologies, new speeds and new professional challenges. In order to help our readers keep up with the progress, we have tried to communicate all the key events for the industry as quickly as possible on our blog. Our engineers and testers actively helped us with this, trying hardware and software innovations on their own experience. All collected information was eventually systematized and became articles for developers, engineers, system administrators and other technical specialists. We are happy to share our own experience with you, and we hope that at least sometimes we were able to help you make the right choice and save your time. Thank you for being with us!
For developers
Serverless by racks
Serverless is not about the physical absence of servers. This is not a container killer or a fleeting trend. This is a new approach to building systems in the cloud. In today's article, we will touch on the architecture of Serverless applications, see what role the Serverless service provider and open-source projects play. In the end, let's talk about the use of Serverless.
Implementing the OpenStack LBaaS UI
Author's note: "I had a lot of trouble implementing the load balancer UI for my virtual private cloud. This led me to think about the role of the frontend, which I want to share first.
For system administrators
From High Ceph Latency to Kernel Patch with eBPF/BCC
Linux has a large number of tools for debugging the kernel and applications. Most of them have a negative impact on application performance and cannot be used in production.
A couple of years ago, another tool was developed - eBPF. It makes it possible to trace the kernel and user applications with low overhead and without the need to rebuild programs and load third-party modules into the kernel.
IP KVM over QEMU
Troubleshooting OS boot problems on non-KVM servers is a tricky business. We create ourselves a KVM-over-IP through a recovery image and a virtual machine.
In case of problems with the operating system on a remote server, the administrator downloads the recovery image and performs the necessary work. This method works great when the cause of the failure is known, and the recovery image and the operating system installed on the server are from the same family. If the cause of the failure is not yet known, it is necessary to observe the progress of the operating system boot.
For fans of "iron"
Meet the new Intel processors
On 02.04.2019/2017/14, Intel announced the long-awaited update to the Intel® Xeon® Scalable Processors family introduced in mid-XNUMX. The new processors are based on a microarchitecture codenamed Cascade Lake and built on an improved XNUMXnm process technology.
From Naples to Rome: New AMD EPYC CPUs
On August XNUMXth, the second generation of the AMD EPYC™ line was announced worldwide. New processors based on microarchitecture It was 2 and built on a 7nm process.
