Japanese crypto exchange Coincheck lost $534 million as a result of compromise of online wallets of its clients. This was the largest reported damage. What will be the statistics for 2019, […]
Zextras PowerStore is one of the most requested add-ons for the Zimbra Collaboration Suite included with Zextras Suite. The use of this extension, which allows you to add hierarchical media management to Zimbra, as well as significantly reduce the hard drive space occupied by user mailboxes through the use of compression and deduplication algorithms, ultimately leads to a […]
Introduction Recently, the popularity of Kubernetes has been growing rapidly - more and more projects are implementing it at home. I wanted to touch on an orchestrator such as Nomad: it is perfect for projects where other solutions from HashiCorp, such as Vault and Consul, are already used, and the projects themselves are not complex in terms of infrastructure. This article will […]
On the eve of DevOpsConf, Vitaly Khabarov interviewed Dmitry Stolyarov (distol), CTO and co-founder of Flant. Vitaly asked Dmitry about what Flant does, about Kubernetes, ecosystem development, and support. We discussed why Kubernetes is needed and whether it is needed at all. And also about microservices, Amazon AWS, the “I'm lucky” approach to DevOps, the future of Kubernetes itself, why, when and how it will take over the world, DevOps prospects and what engineers should prepare for in the bright […]
The next user wants to write a new piece of data to the hard disk, but he does not have enough free space for this. I also don’t want to delete anything, because “everything is very important and necessary.” And what should we do with it? He is not the only one with this problem. There are terabytes of information resting on our hard drives, and this number does not […]
Today we decided to talk about the tools that IT companies and IaaS providers use to automate work with networks and engineering systems. / Flickr / Not4rthur / CC BY-SA Realize Software-Defined Networking With the launch of 5G networks, IoT devices are expected to become truly mainstream, with some estimates exceeding 50 billion by 2022. Experts point out that […]
Background It so happened that the server was attacked by a ransomware virus, which, by a “lucky accident,” partially left the .ibd files (files of raw data of innodb tables) untouched, but at the same time completely encrypted the .fpm files (structure files). At the same time, .idb could be divided into: those subject to recovery through standard tools and guides. For such cases, there is an excellent article; partially encrypted […]
Reflections on where the desire to take the AWS Solutions Architect Associate certification comes from. Motive one: “Axes” One of the most useful principles for any professional is “Know your tools” (or in one of the variations “sharpen the saw”). We have been in the clouds for a long time, but until now these were just monolithic applications with databases deployed on EC2 instances - […]

Photo - Pexels - CC BY According to PWC, the semiconductor technology market is growing - last year it reached $481 billion. But its growth rate has slowed down in recent years. Among the reasons for the decline are the complexity of device design processes and the lack of automation. A few years ago, engineers from Intel wrote that when creating a high-performance […]
Kubernetes Dashboard is an easy-to-use tool for getting up-to-date information about a running cluster and minimal management of it. You begin to appreciate it even more when access to these features is needed not only by administrators / DevOps engineers, but also by those who are less accustomed to the console and / or do not intend to deal with all the intricacies of interacting with kubectl and other utilities. It happened […]
