The IT World is constantly shifting its gears and with the widespread adoption of cloud servers, the demand for cloud services is growing rapidly. If you are curious enough to know about the cloud server, you probably have already heard of or even used the shared hosting or dedicated servers for running your website on webservers, mail servers, and database servers. And I presume that you are deciding to move into cloud because of the scalability problems with the traditional servers.
So, what is a cloud server?
A cloud server is a virtual server which is build on large pool of multiple physical servers, hosted and delivered by cloud computing, thus a cloud can run multiple OS like Linux/Windows using the same resources.
If you are convinced that you want to move your infrastructure to cloud, a critical question immediately follows: What can I do with a cloud server?
The answer is that the cloud server work in the same way as the traditional servers but the features they offer can vary. The cloud enables you to design your application around scalability so that it allows you to expand and contract your application as the traffic fluctuates.
With cloud servers, you have the ability to scale up and down on the fly. Also, there are tremendous benefits of the cloud servers such as greater flexibility, lower total cost of ownership, fast deployment times and hourly billing. Cost-effectiveness is one of the driving factors to shift the infrastructure to cloud as you pay for what you use.
Unlike dedicated servers, cloud servers can be managed with an Application Programming Interface (API) that can assist in integrating applications and other workloads into the cloud using the Representational State Transfer (REST)-based APIs. Furthermore, APIs certainly makes it easier than ever for developers to deploy the applications or setup application in cloud. Cloud service providers offer SDKs in all major programming languages.
There is a misconception aired by some about the security of cloud servers and accessibility but in reality it is easy to make a secure remote connection from your local computer to your cloud server using SSH. Secure Shell (SSH) is a protocol through which you can access your cloud server and run shell commands. You can use SSH keys to identify trusted computers without the need for passwords, and to interact with your servers.
If you are connecting to Linux from Windows, use client called PuTTy, you can download it from this website. If you use Mac OS X, you don’t need to install a third-party client like PuTTY to connect to your cloud server via Secure Shell (SSH). Terminal is a terminal emulation program included with Mac OS X that you can use to run SSH.
The cloud services will only continue to grow as more organizations look for efficient ways to manage their application stacks.
