This article mainly introduces what server terms are, which can be used for reference. Interested friends can refer to them. I hope you will gain a lot after reading this article. Let's take a look at it.

1. Scale out (Scale-Out)

At present, the architecture of the server is divided into two camps, one is the host or box-based Scale up camp representing centralized computing, and the other is the Scale out camp representing distributed computing. Scale up servers increase computing power by adding processors, while Scale out servers increase computing power by adding independent servers, but the line between the two servers is becoming more and more blurred.

Outward expansion means that enterprises can add different server applications according to their needs, rely on multiple hosts for collaborative computing, and improve computing power and reliability through functions such as load balancing and fault tolerance.

two。 Scale up (Scale-Up)

Compared with outward expansion, Scale up refers to the increase of computing resources such as processors on large servers at the back end of the enterprise. In the past, when computers could not keep up with the performance requirements of applications, people would increase server computing resources to upgrade, which is called scale-up.

3. Grid Computing (Grid Computing)

Grid computing is a group of emerging technologies built on Internet. Grid computing system is generally composed of four layers: grid hardware, grid operating system, grid interface and grid application. Its most prominent features are resource sharing, collaborative work and open standards. Grid computing has been a hot spot in recent years, and the idea of applying computing resources on the network anytime and anywhere is becoming a reality step by step.

4. Common operation (Utility Computing)

Public computing mainly advocates an ideal enterprise information architecture, which allows IT services to imitate public services, just like supplying water, electricity and gas.

In the framework of public computing, computing services are supplied at any time, just like water and electricity, and can be provided at any time according to the different needs of different industries or departments, including the automatic provision of computable and measurable IT resources, including servers, storage capacity, business applications and network resources. Users can log in to the computer through the internal network or the public network to obtain computing resources. The billing method is based on usage, such as seconds, minutes or hours of CPU usage.

5. Total cost of ownership (TCO)

TCO refers to the real cost of owning a server, including its management, power, accessories, repairs and time costs. In theory, TCO is a concept that is really worth considering when making server purchases.
