Open source technology has begun to deeply affect the world of cloud computing. There are two main reasons: first, open source software is essentially free, and it is generally not affected by proprietary software copyright models. Many proprietary software vendors, such as Microsoft and Oracle, are trying to maintain outdated and expensive license patterns, even though this pattern has hampered the flexibility of virtualization and cloud computing. Conversely, some open source tools are having a huge impact on the public cloud: Linux and Xen, for example. In addition, there are some other important open source tools also for users ...
Server virtualization technology should be traced to the IBM mainframe virtualization z / VM. Today's content covers CPU virtualization, memory virtualization, IO virtualization, and GPU virtualization. Technical in-depth popular science articles.
When looking for open source cloud computing service providers, companies with strong development capabilities or specific business applications tend to routinely avoid commercial cloud computing service providers. Open source cloud computing platforms such as Eucalyptus, OpenStack and abiquo are expected to succeed in building private cloud computing opportunities for companies. But some problems remain, such as how the Open-source cloud services provider can reflect its value. Who will pull the top? Can the Eucalyptus system win in the brutal competition with OpenStack? Op ...
Virtual Machine Management program is a commodity, then where do we go? Virtualized physical computers are the backbone of the public cloud [note] and private cloud [note], enabling enterprises to optimize hardware utilization, enhance security, support multi-tenant, and so on. Early virtualization approaches were based primarily on analog CPUs, such as x86 on PowerPC Macs, enabling users to run DOS and Windows. Not only do you need to simulate CPUs, but you also simulate other components in your hardware environment, including graphics adapters, hard disks, network adapters, memory, and interfaces. ...

"Editor's note" in the cloud computing ecosystem, there are two types of users that need to use cloud computing resources: the traditional (traditional IT applications) and the emerging Cloud computing Application (Cloud-aware applications) in the Internet tide. A popular metaphor abroad is that in the traditional service mode, it can be imagined that the server is the IT pet (Pets), give them name, carefully raised, when they are sick, you have to repair them; in the new form of application service model, virtual machine ...
A, virtualization virtualization refers to the ability to simulate multiple virtual machines on the same physical machine. Each virtual machine has a separate processor, memory, hard disk, and network interface logically. The use of virtualization technology can improve the utilization of hardware resources, so that multiple applications can run on the same physical machine with each other isolated operating environment. There are also different levels of virtualization, such as virtualization at the hardware level and virtualization at the software level. Hardware virtualization refers to the simulation of hardware to obtain a similar to the real computer environment, you can run a complete operating system. In the hardware virtual ...
Eucalyptus Elastic Utility Computing architecture for linking Your Programs to useful Bae (Eucalyptus) is an open source software infrastructure, Used to compute the flexible, practical cloud computing of a cluster or workstation cluster. It was originally a research project at the University of California at Santa Barbara School of Computer Science, ...
Because of the need to be able to quickly add requests when computing resources, people have developed technologies that allow for the provision of resources, but do not need to know specifically what the resources are and where resources are located. This flexible environment, to provide the necessary resources supply technology, called cloud computing. One of the main reasons why we agree with this change in calculation method is the potential to use a large proportion of fast, large-scale resources in smaller, restricted environments. Due to the widespread adoption of virtual computing, this new computing paradigm is currently commercially viable. Just like virtual machine can build ...
Cloudstack is the Ctrix company's flagship product in the IaaS market, providing flexible deployment and management capabilities for cloud computing resources. In the first half of this year Ctrix will contribute its source code to Apache, Cloudstack become an open source project. The documentation for such open source projects has been perfected, but as a novice in the cloud computing field tries to install and deploy it, there are still more or less challenges. This is the purpose of this article, that is, to faithfully record and try to sum up some of the problems in this process, with everyone ...
