What is different between Rental Server & Cloud Computing

Rental server and cloud computing, A rental server is a form of “sharing one server with multiple users”. This form, also known as a shared server, allows multiple users to share the CPU and memory of a physical server. Therefore, users who use the same server will share the performance of the server with everyone.

One cloud uses a virtual server (a technology to create multiple virtual servers in a physical server) in a physical server provided by a cloud server management company. Of course, since it is physically one server, CPU and memory are shared, but since it is properly allocated and managed for each virtual server, performance is not shared by multiple users.

In other words, “whether or not to share CPU and memory performance” differs greatly between the rental server and the cloud.

Rental server and cloud computing, What is cloud-based rental server?

Rental server and cloud computing, So what does it mean to turn a rental server into the cloud?
Simply put, this means that the service of the rental server you are currently using will be transferred and operated to a virtual server prepared by the cloud service provider.

A cloud that does not share CPU or memory performance may be a good choice as a relocation destination if you feel that the specifications of the rental server are insufficient.

Certainly, moving the rental server to the cloud means transferring it to a server that does not share performance, and you can get the advantages of expandability and free customization described later. However, on the other hand, if you do not understand the difference between the rental server and the cloud, the transfer may not be successful.

Therefore, it is important to understand the differences between rental servers and the cloud, and the advantages and disadvantages, and then select the most suitable server.
From here, we will look at the advantages and disadvantages of cloud computing.

Rental server and cloud computing, Benefits of cloud computing

Rental server and cloud computing, There are four main merits of cloud computing.
◇ No server installation cost In
most cases, there is no initial cost when subscribing to a cloud server, which may lower the hurdle for server installation in terms of initial cost.
◇ Freely customize the server Since
one independent virtual server is used, the server can be freely customized.
Flexible configurations are possible, such as servers with a large amount of CPU and servers that specialize in memory.
◇ Excellent server expandability
Cloud-based servers can flexibly increase and decrease specifications. For example, it is possible to use it at the minimum at first and increase the CPU and memory when the access increases.

Rental server and cloud computing, Disadvantages of cloud computing

Rental server and cloud computing, The following three points are the main disadvantages of cloud computing.
◇ Operation cost is higher than rental server Since the
cloud uses a virtual server, software cost for virtualization is included, and in general, the price with the same specifications may be higher than the rental server. There are many.
Therefore, if you subscribe to a server that will remain up for a month, you need to estimate the operating costs in advance.

◇ Usage fee is pay-as-you-go
Rental servers can be used by paying a certain monthly fee, but most clouds have a pay-as-you-go fee system in which the cost fluctuates depending on the amount of communication and CPU usage. In the case of a rental server, the monthly usage fee does not change no matter how much you use it, so that is a big difference.

In other words, the rental server makes it easy to make a budget / payment plan, but the cloud makes it difficult to make a budget plan. In addition to the high cost of the same specifications, you need to be careful when using the cloud.

When it comes to pay-as-you-go billing,if you use it for only a few days in a month, it will be cheaper than a rental server. However, on the contrary, if you leave the server running and set it to expand automatically when the load becomes heavy, there is a possibility that the charge will jump up.

• Operation is more complicated than rental server Rental servers often have a management screen, and WordPress installation support and backup settings are possible, but there are not many such management screens in the cloud.
• Therefore, it is necessary to set up a proper server administrator to manage the cloud, which is often complicated compared to rental servers.

Rental server and cloud computing, Summary

• Rental server and cloud computing, It is easy to think that the cloud is easy to use because it has advantages such as low initial cost and excellent server scalability and customizability. However, since one virtual server is rented, complicated operations occur and operating costs such as setting up a server administrator are incurred.
• On the other hand, for rental servers, taking CPI as an example, the initial cost is free, and if you add options for a fixed monthly fee, you can receive generous operational support 24 hours a day, 365 days a year.
