(1) The concept of virtualizationVirtualization is the simultaneous running of multiple virtual machines on physical devices that share the CPU, memory, and network of physical devices, but these VMs are isolated from each other.The physical machine is called host (host), and the virtual machine is called guest.(2) Classification of virtualizationVirtual machine scheduling management relies on hypervisor software, according to the location of hypervisor, can be divided into 2 major categories:1,

OpenStack is a free software and open source project, developed and launched by NASA and Rackspace, in collaboration with the Apache license. OpenStack is an open source cloud computing management Platform project, composed of several major components to accomplish specific tasks.

next day the weather is very hot again, you go to buy ice cream (renewal) Is Linux cloud computing a gimmick or is it really just needed?The answer is just need, no way to eat ice cream will need someone to buy! What you need to know to be a Linux cloud computing engineer1, familiar with Linux operating sy

For cloud computing, 2016 was a connecting year, the 10 anniversary of the launch of the AWS Amazon Cloud and the 10 anniversary of Google's first mention of cloud computing. Over the past 10 years, cloud

The full text includes three parts: The first part Part II Part III In the first part of this series, I covered six requirements for enterprise-level OpenStack. Now, I'll focus on the next two main requirements: open architecture and hybrid cloud compatibility. Let's get started right away.Demand 3-open architecture and reduce vendor lock-inWe've talked about building robust

polished.From dozens of to thousands of Taiwan, or even tens of thousands of units, whether the stability of the same as always can not be a problem? As the scale expands, the overall structure needs to do a sufficient job in terms of stability.For example, you need to design multiple Nova APIs and multiple mirrors, load balancing and node high availability, and database concurrency responses.In addition, in the community by the most up-to-the-top upgrade problem--nova,swift,cinder and neutron
