Virtualization *

Hi Habr,

I'm Artyom Karamyshev, a system administration team leader at Mail.Ru Cloud Solutions (MCS). We launched many products in 2019. We've aimed to make API services easily scalable, fault-tolerant, and ready to accommodate rapid growth. Our platform is running on OpenStack, and in this article, I describe all the component fault tolerance issues that we've resolved.

The overall fault tolerance of the platform is consists of its components fault tolerance. So, I'm going to show you step by step tutorial about all levels where we've found the risks.

Hyper-V is more known as a server virtualization technology; however, since Windows 8, it is also available in the client operating system. In Windows 10, Microsoft improved the experience drastically to make Hyper-V an excellent solution for developers and IT Pros.
 
Microsoft Hyper-V, codenamed Viridian, is a native (type 1) hypervisor that directly runs on the hardware, compared to VMware Workstation, VirtualBox, and other type 2 or hosted hypervisors. It was first released in Windows Server 2008, and it allows you to run virtual machines on x86-64 systems.

As mentioned, with Windows 10, Microsoft optimized Hyper-V for developers. Hyper-V allows developers to quickly spin up development virtual machines on Windows 10 with excellent performance, but it is also used in a couple of other development features as a back-end technology, like the Android Emulator, the Windows Subsystem for Linux 2 or Docker Containers. In this article, we will have a quick look at what Hyper-V on Windows 10 can over for developers.

Hi! In this article, I want to explain, in layman’s terms, how steal appears in VMs and tell you about some of the less-than-obvious artifacts that we found during research on the topic that I was involved in as CTO of the Mail.ru Cloud Solutions platform. The platform runs KVM.

Targeted attacks are the most dangerous among the multitude of modern cyber threats. They are also known as ATP (an abbreviation which stands for Advanced Persistent Threat). Those are not viruses that can accidentally get into the computer due to user's carelessness. Neither it is an attempt to replace the address of a popular site in order to cheat billing information from credulous users.
