Virtualization is not a new terminology, but was evolved in the 60s, when IBM started to develop their own virtual memory operating system which was an early incarnation of the IBM System. The movement from IBM pulled large crowd into the development of virtual machines which includes companies such as Microsoft and VMware. After 50 years of changes in technology, now we live in an “Everything as a Service” universe. Organizations are changing their data from physical storage to a more secured virtual environment. Virtualization has created a revolution and now users are more aligned to concepts such as cloud, containerisation, etc. Along with that the presence of some hybrid technologies are associated with data storage. All these bleeding edge technologies are combined contributing to the data management. The blog discuss the future aspects server virtualization and its impact on other technologies such as hypervisor.
Did Server Virtualization Adversely Affect the Prominence of Hypervisor in 2016?
What is Server Virtualization?
Masking of server resources including physical servers, operating systems, and processors from the users is known as server virtualization. The partition of the physical server into tiny virtual servers helps to maximize the server resources. The software used for this purpose is known as virtual or private servers. It is also guests, instances, containers or emulations.
The three popular approaches to server virtualization are virtual machine model, paravirtual machine model, and virtualization at the operating system layer. Apart from maximising of the server resources, server virtualization includes other benefits such as:
- The migration into a virtual environment from a physical server helps to reduce the monthly power and cooling costs inside the data center.
- It helps you to create self-contained lab or test environment on its own isolated network
- Faster server provisioning
- Flexibility in choosing the server equipment as virtual environment replaces the physical environment.
- Improved disaster recovery.
What is Hypervisor?
The program which allows the user to host several virtual machines, in a single system at a time is called hypervisor. It is also referred to as virtual machine manager (VMM). Each virtual machine functions as if it has a separate processor, memory, and resources and is able to run on its own programs. It is achieved solely by the support of the hypervisor as it shares the hardware to the each operating system.
The main function of the hypervisor is to cater to the needs of the guest operating system and to defend multiple instances from interrupting with each other. There are two types of hypervisors they are Type 1 or native hypervisors and Type 2 or hosted hypervisors..
The Impact of Server Virtualization Over Hypervisor
Server virtualization becomes more popular due to its effectiveness in addressing the challenges pertaining to server environment operations. It allows multiple virtual machines to operate on a single server and thus helps to reduce capital expenditures and operational expenses. The involvement of server virtualization changes the dynamics of the data centre. The dawn of virtualization will affect the hypervisor architecture in an adverse way. It includes:.
- Virtualization is affecting the hypervisor architecture in an adverse way. Of course, we could not predict a replacement for hypervisor but it s creating a decline in user rate.
- The container concept is almost embracing the data centres across the world and it has slowed the other efforts such as an open stack. The containers are expected to be the focal point for 2016 along with the inclusion of Microsoft Nano Server into the container table.
- Cloud is one of the systems which getting prominence on 2016. We have reached a point where the cloud is almost is the norm irrespective of the type (private, public or hybrid).
- Even thought Hyper – V is expected to accounts for the major portion of the market share, the hypervisor wars will continue to die down due to its feature parity.
- The launch of technologies such as solid-state drive (SSD) storage and hyper-converged infrastructure are also expected to evolve in 2016 even they are not directly related to server virtualization
Virtualization has started to weaken the hypervisor architectures. When this is confined to the matter of this two server architecture, the total server environment seems to see some other drastic changes. It includes the container concept, cloud systems other technologies such as solid-state drive (SSD) storage and hyper-converged infrastructure. It is expected to see a container explosion in 2016 even though it has little practical implementation issues. Containers have almost conquered the operations of data centres. We have been a great deal of migration into cloud platforms still some cyber security concerns are associated with it. In brief, the users are showing a tendency to shift to virtual platforms rather than physical servers prior to the increased security concerns.
