When you finish reading this article; You will master the “Cloud Server” technology that you frequently encounter on the Internet and you will find an answer to the question “What is a Cloud Server?” with a narrative that is far from technical language. You will also learn industry terms such as “SSD Cloud Server“, “Linux Cloud Server” and “Windows Cloud Server” and learn more about “The difference between Cloud Server and VPS”. Before you start reading our article, which describes Cloud Server technology in the finest detail but uses the simplest language possible in doing so, we recommend that you review this content that answers the question “What is a server?”
From a physical server pool to virtual servers where virtualization technology is obtained; is called a cloud server. All resources on the cloud server, such as storage, processor, and RAM, are sourced from this pool. There is the possibility to increase or reduce resource capacity instantly. This technology, which needs physical servers in the data center to be created, does not need any physical intervention to be managed by the user.
To describe the last sentence of the paragraph above with an example; to make hardware improvements or changes to a physical server, it is necessary to go to the data center in person and interfere with the hardware of the server. For example, if you’re going to increase memory capacity, it is necessary to connect a NAS device or replace the hard disk of the server.
On cloud server, all kinds of hardware changes and resource increase or downgrade are done virtually. To put it simply, you do not need to physically interfere with your hard disk to change the storage of drives C and D on your computer. From the interface of Windows, it is possible to assign the desired capacity to the desired disk. As soon as you press the “enter” key, the new capacity of your disk is also defined. Here on cloud servers, it works with logic. You can set all the resources you need on your server as if you were setting limits on your computer’s hard disk. You can instantly reduce or increase your resource needs. In fact, on some cloud server services, this process is so flexible that you can perform custom resource definitions for certain days of the week or certain times of the day. Because cloud server are actually charged on an hourly basis.
From what we’ve told you so far, you should have learned the basics of cloud server operation logic. It’s time to explain how the cloud server work. Don’t worry, we will continue our article with examples and the simplest form of narration.
The way cloud server work is very similar to CDN services. If you are unfamiliar with CDN technology, we recommend that you read our article below to get detailed information. In this way, the answer to the question “How does the cloud server work?” will sit more clearly in your mind.
Many cloud server services have physical servers at various points around the world. The cloud server resources you lease are obtained through virtualization from a giant server park created by all of these servers. As soon as your visitor wants to connect to your site, they are routed to the server closest to them geographically, which means they have access to your site through that server. Since the distance between your visitor and your site is shortened, access to your site is accelerated and user satisfaction increases.
There are many advantages to getting hosting through the cloud server. The first of these advantages, as we mentioned in the next title; the positive impact of loading and navigation speed by transmitting your site content from the nearest point to the user. The acceleration of your site also has a positive effect on your SEO work.
Another advantage is that your site is not affected by these failures during possible hardware failures. Because if one of the hundreds of physical servers in the cloud server park fails, other servers automatically increase their virtual capacity and your visitors continue to navigate your site without even realizing the failure. You won’t have to wait for any hardware failures to be fixed.
Losing data on a physical server that doesn’t use cloud technology can literally turn into a nightmare. Because if you do not keep a backup of your data elsewhere, it is possible that all your efforts to your site will go to waste. In some cases, it doesn’t even help to upload the site backup to another platform on a daily basis. Especially on sites where instant data is logged in by users such as forum sites or e-commerce platforms where new orders are created at any time; you need to take an hourly or even minute backup. To be able to make backups at such a time interval and quickly; Although theoretically possible, it is not possible to apply it in practice. On cloud servers, all servers in the system must fail at the same time for your data to be lost. As you can appreciate, all physical servers in this system, created from hundreds of servers in different locations, are less likely to fail at the same time than one in a million. Therefore, it is impossible to lose data on cloud server systems wherever it is.
Updating the hardware resources of cloud servers occurs faster than physical servers. Because there is competition in the cloud server market, server companies constantly try to keep up with the new technology by updating their systems. Moreover, in hardware improvements and system maintenance, your site uses the resources of other servers running open in the server cloud and your site is not closed for access. When hardware is changed to increase resources on an ordinary physical server, your site may be 0.8%. Therefore, hardware changes occur less on physical servers. You can also increase resources on the cloud server in minutes if your existing server resources are not sufficient. On the physical server, you may need to completely change the server on which you are running the server service.
Storage technology, which we call “hard drive” or “HDD”, has evolved and has been replaced by SSD, or “Solid State Drive” technology. If you have no idea about storage technologies, reading our article below, in which we explain the difference with SSD technology and HDD, will allow you to understand the subject more clearly.
To put it simply, SSD is a data storage method that uses the method of recording to electronic circuits. Writing and reading data on the SSD occurs completely electronically, there are no mechanical parts, the read and write speed is higher. In the HDD storage method, reading and writing is done with a device called “read/write head”. This device is mechanical, has a short lifespan, has a lower data read and write speed than the SSD. For this reason, servers that use SSD for data storage run faster than servers that use HDD, and visitors access the site faster. At the same time, SSD servers are more advantageous in terms of SEO because they promise fast site access.
Almost all cloud server services use SSD’s for their physical servers. Therefore, these servers are also defined as “SSD cloud servers”.
SSD servers technically support Linux and Windows operating systems. Because in this technology, virtual servers are obtained from physical servers by virtualization method. It is also possible to install the desired operating system on the resulting virtual servers.
The majority of the cloud servers sold on the market use the Linux operating system. The main reason for this is that; PhP encoding language is more used and scripts written in this language work more stablely on Linux servers.
The cloud server and VPS server are basically two different hosting systems. VPS (Virtula Private Server); is the process of virtualizing a physical server and allocating it to independent manageable servers. The total resource capacity of VPS’s on a server cannot be greater than the total resource capacity of the server on which it resides.
VPS servers are affected by hardware failures on the physical servers where they are located. In case of possible data loss, compensation is not easy. Because the backup of your site is inside the server that is performing hardware failure. On cloud servers, your data is backed up on other servers in the server park.
Now that you’ve finished reading our article, you’ve mastered the cloud server technology enough. You can continue to follow our blog in order to be informed in other fields of web technologies.
