Server Virtualization – Enhance Operational Efficiency, Scalability for Success
Every organization has to be fully equipped to meet the challenges of a competitive market that thrives on excellent product/service delivery.
Being backed by seamless technology and multiple backup resources gives an organization the much-desired edge over similar service providers.
Among many such technologies that bolster a company on its journey to growth is an effective solution with immediate response to the organization’s scalability needs i.e., ‘Server Virtualization’.
What is Server Virtualization?
Server Virtualization is the division of a single server into multiple virtual servers with their own set of Operating Systems (OS) and applications.
The server virtualization arrangement helps a company divide its operations to manage complex workflows.
For example, a team of graphics personnel can work on a Mac OS, whereas a team of accounting professionals will use a Windows environment.
To setup virtual servers, the server administrators utilizes a software application such as a hypervisor to divide one physical server into numerous isolated virtual environments.
Challenges That Paved the Way for Server Virtualization
In the absence of virtualization, enterprises were faced with challenges including server sprawl, where resources were not used to the full limit and were still consuming organization floorspace.
Furthermore, electricity bills kept spiraling out of control, manual processes were inefficient in keeping up with rising production demands and managing data-center environments became a cumbersome task.
But today, server virtualization has transformed the way a company manages its resources to fulfill its business growth needs.
How Server Virtualization Helps Firms?
Driven by the need for growth, cost savings and technological advancements, organizations adopt server virtualization owing to its following features:
- Reduces hardware costs: Winning in the area of operational costs is what most organizations look for. With server virtualization, hardware utilization has improved significantly because one physical server can now power multiple virtual machines. This also boosts application performance since each application has its own virtual server.
For companies with thousands of servers, the need for physical space reduces drastically, in turn bringing down maintenance costs. In 2011, the International Data Cooperation (IDC) reported a 40 percent reduction in hardware and software costs for IT departments who adopted server virtualization. According to VMware, server consolidation reduces energy costs by up to 80 percent.
- Increases Server Provisioning and Deployment: Setting up virtual servers is now a matter of minutes, reducing the time and money spent on provisioning physical servers. Companies do not have to waste time on filling out purchase order forms, waiting for physical servers to arrive or wait for operating systems and applications to be installed.
- Enhances Scope for Disaster Recovery: Server virtualization greatly boosts disaster recovery wherein, backing up critical company data on a virtual server becomes easy, quick and safe. Most enterprises have dedicated software for automating a failover during a disaster. When your data center is affected due to a disaster, your infrastructure is quick to take action based on its programming to deal with an emergency.
- Increases Productivity: Having to do away with physical servers equals to directing your staff to more business growth-driven tasks. When IT staff does not have to invest their time in provisioning applications or OS that used to take weeks, they are naturally driven to taking new business initiatives and revenue-generating tasks.
Types of Server Virtualization
Server virtualization has several variations including:
- Standard hypervisor-based Virtualization
- Para Virtualization
- Hardware-assisted Virtualization
- Kernel-level Virtualization
- System-Level or OS Virtualization
The Future of Server Virtualization
The global server virtualization market is expected to earn USD 8 billion by 2023 with a massive CAGR of 7 percent between 2017-2023.
Factors that drive server virtualization include:
- Software maintenance revenue with increased adoption of on-premise server virtualization software
- Proliferation of technology such as cloud and OS container-based virtualization
- Hyper-converged integrated system and emergence of software-defined data center solution
Despite the dawn of containerization and serverless computing, server virtualization is still an important technology for large enterprises.
The Global Server Virtualization market is driven by some leading companies including Citrix, Oracle, Microsoft Corporation, Red Hat and VMware, among others. The VM saturation estimation is as high as 90 percent.
Thinking about the future of moving mission-critical data, it is difficult to move mission-critical applications on VMs to containers or serverless platforms.
Users with heterogeneous environments will likely continue to use VMs because containers need to run on all the same OS and can’t be mixed between two OS platforms.
