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 ...

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 　　Many proprietary software vendors, such as Microsoft and Oracle, are trying to maintain outdated and expensive license patterns, even though this pattern has hampered the flexibility of virtualization and cloud computing.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 ...

When developing internal and external applications, organizations are increasingly using open source code-which is reasonable. Using free pre-built components rather than writing your own code can significantly shorten application development time and improve the probability of software development success. 　　When developing applications, the development team can easily use hundreds of more open source libraries, frameworks and tools, and countless code from the Internet. However, open source code is risky-even the most widely recognized code base. No one can guarantee that the open source code will not have a bug, nor guarantee it in the development process with the enterprise should ...

People often ask me if they really should believe in Oss. In other words, the worry is: is the OSS the angel that brings us a good life, or is it a demon that destroys our lives? As a matter of fact, this problem has been raised since the beginning of Linux and various BSD (Berkeley Software distribution) operating systems. In reality, any organization or enterprise is very cautious in planning to use a free software that is not from a reputable merchant. As a routine, generally ...

In the field of telecommunications and it, a complete system consists of various kinds of basic physical resources and software resources, the basic physical resources provide computing, storage, network and other hardware capabilities, and all kinds of software constitute a variety of colorful applications. 　　These applications are developed by different manufacturers, based on different operating system platforms, using different software architectures, with different deployment patterns, the application of diversification will inevitably bring the complexity of software management. The software management described in this paper mainly refers to the lifecycle management of the software in the field, including the release of software, configuration management, distribution and deployment, patch management 、...

If you've been hitting the IT industry for some reason in recent years, then you've probably heard the word "Internet of Things." According to Gartner, although people are very much interested in the Internet of Things, but for the substantive development of the Internet of Things is not large. The number of devices connected to the network in 2009 was less than 1 billion, but Gartner predicts 26 billion devices will be connected to the network by 2020, generating $ 300 billion in revenue for manufacturers and service providers. all...

Do not simply think that the mobile device as an application terminal is the management of mobile software. Mobile Internet has spawned a lot of new applications different from the past, and mobile applications even lead to changes in the management software market. Management software has ushered in a mobile storm. The veteran manufacturers are gearing up to make changes. The newly challenged ambassadors are ambitious. A contest involving strategic vision, technology platform, application innovation and financial strength has started. Mobile Internet has undoubtedly become the current IT industry, one of the biggest hot spots. 2014 Gartner released strategic top ten technologies and ...

Cloud management is increasingly well known and is becoming a hot topic for now, with every emerging company and established vendors providing some tools to manage the cloud environment. There are a wide variety of tasks, such as monitoring tools, configuration tools, and tools in between. On the market there are natural fog (vaporware), this kind of tools to dazzle people, want to quickly have a certain understanding and clear, it is not easy. If you deploy a cloud that is not a mission-critical environment, but rather a fairly static environment, you may not need to configure the system dynamically. In the ...

Many business owners with only more than 10 to dozens of employees ask if they don't want to spend thousands or even million to buy a database software and ask if there are any free database software available. In fact, there are a lot of small business owners in this type of enterprise, their company needs a small database software to statistics the company's some product data and the information of the storage, the amount of data is really small. As I've seen before, some small businesses use office-brought access small databases, but still feel less convenient. Here, the editor recommends several open source databases for small business use ...

Big data has almost become the latest trend in all business areas, but what is the big data? It's a gimmick, a bubble, or it's as important as rumors. In fact, large data is a very simple term--as it says, a very large dataset. So what are the most? The real answer is "as big as you think"! So why do you have such a large dataset? Because today's data is ubiquitous and has huge rewards: RFID sensors that collect communications data, sensors to collect weather information, and g ...
