Another user wants to write a new piece of data to the hard drive, but they do not have enough free space for that. They also don't want to delete anything, as "everything is very important and necessary." So what should we do with them? This problem is faced by more than just them. Terabytes of information are lying on our hard drives, and this amount is not shrinking […]
Today, we decided to talk about the tools that IT companies and IaaS providers use for automating work with networks and engineering systems. / Flickr / Not4rthur / CC BY-SA Implementing software-defined networks It is expected that with the launch of 5G networks, IoT devices will find truly widespread adoption — according to some estimates, their number will exceed 50 billion by 2022. Experts note that […]
Ahead of DevOpsConf, Vitaly Khabarov interviewed Dmitry Stolyarov (distol), the technical director and co-founder of the company “Flant.” Vitaly asked Dmitry about what Flant does, Kubernetes, ecosystem development, and support. They discussed the necessity of Kubernetes and whether it's needed at all. They also covered microservices, Amazon AWS, the 'I’ll get lucky' approach in DevOps, the future of Kubernetes itself, why, when, and how it will take over the world, the prospects of DevOps, and what engineers should prepare for in the bright […]
Introduction Recently, the popularity of Kubernetes has been rapidly growing — more and more projects are implementing it. I would like to touch upon an orchestrator like Nomad: it is well-suited for projects that already use other HashiCorp solutions, such as Vault and Consul, and where the projects are not complex in terms of infrastructure. In this material, we will […]
Zextras PowerStore is one of the most sought-after extensions for the Zimbra Collaboration Suite, part of the Zextras Suite. Utilizing this extension, which adds hierarchical media management capabilities to Zimbra and significantly reduces the disk space consumed by user mailboxes through compression and deduplication algorithms, ultimately leads to substantial savings in storage space.
Happy Friday everyone! Friends, today we continue our series of publications dedicated to the 'DevOps Practices and Tools' course, as classes in the new group will start at the end of next week. So, let's get started! Monitoring is simple. This is a well-known fact. Raise Nagios, run NRPE on a remote system, configure Nagios to the NRPE TCP port 5666, and you have...
In the world of Postgres, indexes are crucial for effective navigation through the database storage (referred to as the 'heap'). Postgres does not support clustering for it, and the MVCC architecture leads to the accumulation of many versions of the same tuple. Therefore, it is essential to be able to create and maintain efficient indexes to support applications. I present to you […]
Photo — Pexels — CC BY According to PWC, the semiconductor technology market is growing — last year it reached a level of $481 billion. However, growth rates have recently declined. Among the reasons for this downturn are the complexities of device design processes and a lack of automation. A few years ago, engineers from Intel noted that when creating high-performance […]
Kubernetes Dashboard is a user-friendly tool for obtaining current information about a running cluster and providing minimal management. You appreciate it even more when access to these capabilities 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. Thus it happened […]
The internet is full of articles about service meshes, and here’s another one. Hooray! But why? Because I want to express my opinion that it would have been better if service meshes had come about 10 years ago, before the emergence of container platforms like Docker and Kubernetes. I do not claim that my point of view is better or worse than others, but since service meshes are quite complex […]
In this material, we will attempt to consider an interesting and useful element of IT infrastructure, such as VoIP traffic monitoring systems. The development of modern telecommunication networks is astonishing: from signaling bonfires they have come a long way, and what seemed unimaginable before is now simple and mundane. Only professionals know what lurks behind the everyday nature and widespread use of achievements in the field of information technology. The diversity of environments […]
Hello, colleagues! In the previous material, we got acquainted with a useful and, as you might notice, quite necessary element of VoIP infrastructure—the traffic monitoring system, or SMT for short. We learned what it is, what tasks it solves, and also noted the most prominent representatives presented to the IT world by developers. In this part, we will explore the principles by which SMT is implemented in IT infrastructure […]
