Elastic Cloud Server (Elastic Cloud Server, ECS) consists of CPU, memory, operating system, of Cloud drive components, the basis of Elastic Cloud Server to create success, you can use your local PC or physical Server, use Elastic Cloud on Cloud Server, flexible pricing model, namely rent box, on-demand purchase/release, VM shut down not to collect fees, authors power duara rendering efficiency, provide 208 vcpu, 4096 gb of memory, leading the industry's top force
Industry first being forward PPS instance, single instance network bandwidth can reach 44 largest GBPS, maximum forwarding packets rate can reach 12 million PPS
Provide on-demand, package cycle, bidding and other pricing mode, meet the demand of all kinds of business use


Server must have a certain "scalability", this is because the enterprise network can't be constant for a long time, especially in today's information age, if the server is not certain extensibility, when users increase is incompetent, a value of tens of thousands, even hundreds of thousands of servers is eliminated in a short time, this is no company can afford, in order to keep the extensibility, usually need to have a certain extensible space on the server and redundant parts (such as disk array position, PCI and memory stick slot, etc.),


Scalability of hard disk is extensible, embodies the CPU can upgrade or extension, whether the system

2, easy to use


Server function relative to the PC for many complex, not only refers to the hardware configuration, more refers to its software system configuration, the function of the server to achieve so much, there is no comprehensive software support is unable to imagine, but only one (1) the software system, and may cause the loss of the use of server performance, managers can't effective operation, easy to use and server is the server is easy to operate, users navigation system is perfect, chassis design is human nature, is there any key to restore function, operating system backup, and have enough training support, etc.,




3, usability etc.


For a server, a very important aspect is its "availability", namely the selected server can meet the requirements of long-term, stable work, can't often out of the question, namely reliability,


Because the server is facing the entire network of users, rather than a single user, in large and medium-sized enterprises, usually requires that the server is never interrupted, in some special applications, even if no user use, some servers have to constantly work, because it must continue to provide users with link service, whether at work, or work, whether it's working day also, and rest, holidays, this is the required server must have the root cause of the high stability,


Generally dedicated servers are 7 x24 hours non-stop work, especially as some of the larger network servers, such as large companies use server, WEB server, and to provide public service of the WEB server, etc. Especially, for the server, perhaps really work boot times only once, that's just it is to buy back the full installation configured put into use after that time, after that, it non-stop work, until completely scrap, if ready to go wrong, the Internet cannot maintain normal operation for a long time, in order to make sure that the server has a higher "availability", in addition to various parts quality pass, still can take the necessary technology and configuration of the measures, such as hardware redundancy, online diagnosis,






4, manageability


The main features of the server, there is another important feature, that is the "manageability" server, although we say that the server need to constantly continue to work, but it is a good product are likely to fail, people used to say, for one is: don't know it can be bad, but don't know when it bad, although the server with enough protection in terms of stability, but also should have the measures necessary to avoid the error, and found the problem, and there is something wrong with the can get timely maintenance, this not only can reduce the server, the chance of error at the same time also can greatly improve the efficiency of the server maintenance, namely serviceability,


Server manageability also reflect on the server to have intelligent management system, have automatic alarm function, have an independent management system, is there a LCD monitor, etc., only in this way, the administrator can easily management, efficient work,
