I find it very confusing to see a modest IT infrastructure with little or no virtualization at all, and I'm even more surprised when I learn that they have no intention of accepting virtualization in the near future. Whether it's out of the "get out of my way" attitude or simply to reduce the budget, it is crazy to stick to the traditional physical infrastructure today. First, what do these companies buy as servers? If they replace old single and dual-core servers with new four-or-quad servers and simply move services, they already have enough ...

On the EC2, I used the Rightscale ami as the V1 version of Centos5, which has a kernel version of 2.6.16. You can use the following methods to upgrade to 2.6.18. Because Amazon allows you to select the kernel version at startup, Amazon offers the latest kernel version of 2.6.18 (in fact, Rightscale is using Amazon's 2.6.18 kernel), so you can choose to use 2.6.18 kernel startup and then in ...

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 idea of using the Internet to provide IT capabilities as a service is relatively new, but recently people have reached a climax in their attention. Infoq has also published several articles, such as "Introduction to Virtualization" and an article on virtualization security, but there is still a lack of comparisons between different cloud providers. 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. ...

With the start of Apache Hadoop, the primary issue facing the growth of cloud customers is how to choose the right hardware for their new Hadoop cluster. Although Hadoop is designed to run on industry-standard hardware, it is as easy to come up with an ideal cluster configuration that does not want to provide a list of hardware specifications. Choosing the hardware to provide the best balance of performance and economy for a given load is the need to test and verify its effectiveness. (For example, IO dense ...

This week, we released some great updates to the Windows http://www.aliyun.com/zixun/aggregation/13357.html ">azure." These new features include: computing: New dual-core CPU 14GB RAM Instance options virtual machine: Support Oracle software mirroring and management of stopped virtual machines Active Directory: More powerful directory management and universal spending limits that support multifactor validation: RESET spending limits, MSD ...

In the following modes, these systems can help cloud storage technology serve more mainstream storage requirements. There are many types of automated layered systems, with the least impact and the safest way to use them as a cache for storing dynamic data. Automatic tiered systems for caching types copy Dynamic Data from traditional mechanical storage to a cache (RAM or Flash state disk) based on high speed memory. In this copy mode, an automated layered system is used as a large read cache, with little or no unique copy of the data. Keep unique data pairs even when they are written to the write accelerator by caching the inbound write ...

Automated tiered Systems (automated tiering system,ats) migrate data between different storage tiers. If the data is dynamic, it is migrated to the upper tier of storage and is eventually stored in a solid state disk (SSD). There are many types of automated layered systems, with the least impact and the safest way to use them as a cache for storing dynamic data. 　　In particular, these systems will help cloud storage move towards the mainstream. Automatic hierarchical system of cache types will be dynamic data from traditional mechanical storage ...

Virtualization vendors may be promoting the potential of putting 20, 50, or even 100 virtual machines on a single physical server, but IT managers and industry experts say these ratios are dangerous in a production environment, causing performance problems or worse disruption issues. In the test and development environment, companies can put 50 virtual machines in a single physical host, said Andimann, vice president for research at Colorado State Boulder's Business Management Association (EMA). However, when it comes to important tasks and resource-intensive applications, the virtual machine ...

Microsoft today announced a new desktop management tool, Windows Intune, designed to provide management and security services to Windows PCs over the front end of the network, mainly for small and medium business users.     Traditional software like this requires local server support, but Windows Intune is a cloud computing service hosted by Microsoft servers, which eliminates the cost of server configuration for the enterprise. Microsoft Desktop Management Tool window ...
