Virtualization has set the tone for many companies around the Globe. The advantages and opportunities that come along with it have paved its way through the promising world of information technology.
The concept of virtualization is frequently tied with the cloud computing technology. This technology talks about fully operational systems that run virtually within a set of hardware. Through virtualization, the system resources of a particular hardware can be shared equally or in different levels by multiple operating systems that run different applications and services. Cloud computing, on the other hand, is the technology that thrives with the concept of virtualization. It is a group of virtualized systems that can dynamically allocate and transfer resources based on the client’s requirement with minimal to no service downtime requirement.
Virtual Private Server or VPS also functions through virtualization and to some extent are also visible to the cloud setup. These servers run the same features and capability like that of the traditional hardware-based server systems. The only difference is that the servers are virtualized and most of the time taken as a service from many available hosting providers.
VPS can run any available server platforms such as Linux, Unix, or High availability servers. Any platforms that run through traditional hardware will definitely run through VPS. However, compatibility of the application itself will depend on the platform that an administrator would prefer to use. Compatibility-wise, High availability servers have been a leader since the Windows platform has been a standard for most server application and database. Linux VPS on the other hand thrive on it being an open source system. Since no additional licenses are required to operate the system, Linux servers tend to cost less compared to High availability servers.
One of the major reasons for the booming of the virtualization industry is the cost savings factor that it brings to its clients. Since it is virtualized, there will be no capital expenditures included on the budget. Though operational cost would increase due to hosting costs, it is still more cost effective to invest in virtualized systems rather than buying expensive hardware.
Scalability has also been one of the driving factors behind the movement to virtualization. Administrators can easily scale up or down the resources of their systems depending on the application requirement and bulk of traffic accessing the servers. This feature further intensifies the efficiency of the hardware itself. Physical resources are segregated to the number of virtual machines within its core and can dynamically scale, leaving spare resources. This spare however serves the purpose of being a backup reservoir once any servers needs an extra boost to power up the systems running within it.
Some high profile companies prefer that their servers are all intact within the company’s data centers. Web hosting is not an option this time as they are conscious about the security of data being processed by the server systems they manage. Nonetheless, VPS technology still can be used by these companies through building their own private cloud.
Companies may acquire server blades and build their own network infrastructure. VPS technology will provide hardware efficiency and will lower costs. Most firms prefer High availability servers and its Hyper V platform due to its robustness and product support availability. Cloud-based companies also enjoy the benefit of their own private cloud by dynamically allocating resources to the systems that need it most. However, bandwidth and network reliability comes into great consideration for those that prefer to build their own private cloud. Bandwidth also constitutes cost and in some countries, the numbers are just ridiculously high that it further makes the savings computation more complicated.
