How Much Does More Ram Cost

The cloud infrastructure, such as Amazon EC2, has proven its value worldwide, and its ease of scaling, out-of-the-way, on-time billing, and so on, has freed developer creativity more thoroughly, but don't overlook the virtualized environment that was once considered a performance killer for applications and databases. Despite the performance aspect, cloud vendors have been looking for ways to improve, but as users of us, our own performance optimization tools are also essential. On the entity server, Aerospike has shown the peak of the million TPS, and now we are dedicated to improving the performance of cloud applications ...

Today's demand for data centers is solid and effective, and this should be done first by "reasonable use". While idle resources are a waste of money for an environment. But if you fail to make a reasonable resource allocation to the frequently used data center, it will lead to a dangerous scene. A single hardware failure may cause other physical hosts to fail. The challenge for IT managers is to use and manage computing resources across the entire environment (usually including physical, virtual, and cloud resources). This article will discuss resource planning and problem mitigation as a means to achieve the goal of resource optimization. We will also ...

The fastest way to store a computer system is the ram traditionally used primarily as memory. As the access performance of the hard drive has deteriorated over the years, and the cost of RAM has been decreasing, many researchers have been exploring how to replace the hard disk with memory in recent years. As early as the 1980, David DeWitt and Garcia-molina and so on published a main memory database paper. Steven Robbins's article points out that the Turing Prize winner, Jim Gray, is more explicit about the idea that "memory will be a hard drive and the hard drive will become a tape."

This article compares three cloud computing providers, which provide a server-centric solution, starting with a description of how to start three cloud computing services and then comparing the performance, price, and availability of services to three service providers. ...

Everyone wants the computer to start immediately into the Windows system without waiting, or the system in the use of the time will not be more and more slow, but for a variety of reasons often make these wishes can not be achieved, or even a startup on the crash or use the situation is more and more slow to occur often. In fact, sometimes Windows start slow is not its own problem, but some equipment or software. This article is the software, hardware and virus three major aspects to analyze the system slows down the reason, and provides a system-specific acceleration techniques. ...
