No matter whether you run a small, a medium or a large business unit, using a powerful server is one of the must do’s for your business. In order to meet the constantly increasing IT requirements, the servers of your organization have to be extremely powerful so that these can handle any sort of critical tasks or operations. One of the simplest and most conventional ways to handle the entire server operations is to assign a major service or an application to each of the servers. There are certain advantages of this approach of assigning one application per server. For instance, you can easily identify a problem as soon as it occurs. Following this approach, you can also streamline the complete network, ensuring less effort on behalf of the administrators.
If you are planning to implement virtualization solution for your business, there are certain important things that you need to keep in mind. The benefits of virtualization are quite obvious. However, in order to reap the maximum possible benefits, you need to handle the process efficiently. Here are some of the important aspects of virtualization that you must take care of –
• Operating system rebooting – Most of the embedded systems are built for maximum possible uptime, 100% in most cases and this is why operating system rebooting is often overlooked by most of the business owners. However, it’s important to check what happens if there is an OS crash. Make sure, even if an OS crash occurs, an automatic OS reboot will be performed. This shouldn’t interfere with any of the other processes and it should get handled independently.
• Type of hypervisor – While talking about virtualization, it’s important to know about the hypervisor that is also known as a virtual machine manager or a VMM. This is the platform that allows more than one operating systems to run simultaneously. Broadly, there are two types of hypervisors – hosted and bare metal and the denomination of a VMM is determined by the fact that it’s placed a level above the supervisory program. Although it seems that there is no major difference in these two types of hypervisor, there is a significant difference in the way the applications are tested and run. You should choose any of these two based on your business requirements.
• Method of virtualization – No matter which type of hypervisor you opt for, mainly there are three virtualization processes and you must choose the right one for your business. One of these three methods is based on the process of binary hypervisor translation. This method allows more than one operating systems to be run simultaneously, without any sort of conflicts. On the contrary, if you decide to use hypervisors with hardware assist, you will have to opt for embedded CPU virtualization so that the control is automatically passed, whenever required. The third method is known as paravirtualization. This ensures better performance than the other two methods since this interacts with the hypervisor directly, via an application programming interface.
Make sure you consider all the three factors thoroughly before you opt for a virtualization solution. Apart from these, you should also consider factors like scopes of multiprocessing and deployment of work.Tags:
