I was intrigued by this, so I decided to create a memorandum (guide). Start - Alert In the batch server that I use and maintain, there is a regular process that collects data from the last month once a day from […]

Hello, Habr! In the comments on one of our articles about flash drives, readers posed an interesting question: “Why do we need a flash drive with hardware encryption when we have TrueCrypt?”, and even expressed some concerns about “How can we be sure that there are no backdoors in the software and hardware of the Kingston drive?”. We provided concise answers to these questions, but then decided to […]
Hello, Habr! In this article, I will discuss the generation of pseudo-random numbers among participants who do not trust each other. As we will see below, implementing a “nearly” good generator is quite simple, while creating a very good one is challenging. Why is it necessary to generate random numbers for participants who do not trust each other? One application area is decentralized applications. For example, an application that […]
Balloon Man by Cimuanos Scalability is a key requirement for cloud applications. With Kubernetes, scaling an application is as simple as increasing the number of replicas for the corresponding deployment or ReplicaSet—but it is a manual process. Kubernetes allows you to automatically scale applications (that is, Pods in a deployment or ReplicaSet) declaratively using the Horizontal Pod Autoscaler specification. By default […]
Given the number of questions we've been receiving about SD-WAN, the technology seems to be gaining substantial traction in Russia. Vendors, of course, are not idle and are offering their concepts, while some bold pioneers are already implementing them in their networks. We work with almost all vendors, and over the years in our lab, I've had the chance to delve into the architecture of each major […]

Hello, Habr. Today, I continue the series of publications that I wrote specifically for the launch of the new stream of the 'Software Architect' course. Introduction Choosing an architectural style is one of the fundamental technical decisions when building an information system. In this series of articles, I propose to explore the most popular architectural styles for building applications and answer the question of when each architectural style is most preferable. […]
Surely, everyone involved in the implementation of IPv6 or at least interested in this set of protocols knows about Google's IPv6 traffic graph. Similar data is collected by Facebook and APNIC, but for some reason, Google's data is the standard benchmark (although, for instance, there's no visibility into China). The graph is subject to noticeable fluctuations — traffic is higher on weekends, and noticeably […]
Welcome to the second publication of the article series dedicated to Cisco ISE. The first article covered the advantages and differences of Network Access Control (NAC) solutions compared to standard AAA, unique features of Cisco ISE, architecture, and product installation process. In this article, we will dive deeper into creating accounts, adding LDAP servers, and integration with Microsoft Active Directory, as well as nuances […]
We are increasingly receiving requests from clients such as: "We want something like Amazon RDS, but cheaper"; "We want something like RDS, but everywhere, in any infrastructure." To implement such a managed solution on Kubernetes, we looked at the current state of the most popular operators for PostgreSQL (Stolon, operators from Crunchy Data and Zalando) and made our choice. This article shares our experience and […]
