A virtualisation solution offered by an IT solutions provider in Sri Lanka, refers to the software or technology that enables the creation and management of virtual resources within a computing environment. It allows for the abstraction and isolation of physical resources, such as servers, storage devices, networks and operating systems, from underlying hardware.

Virtualisation solutions utilise a layer of software called a hypervisor or virtual machine monitor (VMM) to manage and allocate the physical resources among multiple such machines or environments. The hypervisor acts as a mediator, enabling multiple virtual machines to run on a single physical machine, thereby maximising resource-utilisation and improving efficiency (as well as bringing down related costs).

Different types of virtualisation solutions for business
There are several different types of virtualisation solutions available for businesses, each catering to specific areas of IT infrastructure. These include:
• Server virtualisation: This involves creating multiple virtual machines on a single physical server, and allows for better ...
... utilisation of hardware resources by consolidating multiple servers onto a smaller number of physical machines through a virtualisation solutions provider. These types of solutions include VMware vSphere, Microsoft Hyper-V and KVM.
• Desktop Virtualisation: This allows multiple virtual desktops to run on a centralised server, which users can access remotely from their device. It offers benefits such as centralised management, improved security and the ability to run legacy applications on modern hardware. Common solutions of this type include Citrix Virtual Apps and Desktops, VMware Horizon and Microsoft Remote Desktop Services. With the high Lenovo, HP and Dell desktop prices in Sri Lanka, this is far more cost effective and beneficial.
• Network virtualisation: This involves decoupling the network functionality from the physical network infrastructure. It allows for the creation of virtual networks, logical switches and routers, providing greater flexibility and agility in network management. Solutions like VMware NSX and Cisco Application Centric Infrastructure (ACI) enable this.
• Storage virtualisation: This abstracts physical storage resources and provides a virtualised view of storage to applications and users. It allows for centralised management, efficient storage allocation, and features like snapshots, replication and data migration. Solutions like VMware vSAN, Dell EMC Unity and NetApp ONTAP provide storage capabilities for businesses.
• Application virtualisation: This separates the applications from the underlying operating system, allowing them to run in a virtualised environment. It eliminates conflicts between applications, simplifies application deployment and management, and improves compatibility across different operating systems. Solutions like Citrix Virtual Apps, Microsoft App-V and VMware ThinApp enable this.
• Data virtualisation: This combines data from multiple sources, such as databases, files and web services, into a single virtual view. It provides a unified data access layer, allowing users and applications to access and query data without the need for data movement or duplication to access and query data without the need for data movement or duplication. These types of solutions include Denodo, IBM InfoSphere Federation Server and TIBCO.

Businesses often use a combination of these solutions based on their specific requirements to optimise their IT infrastructure and improve operational efficiency.

How do virtualisation solutions help businesses?
• Cost savings: They enable server consolidation, allowing multiple virtual machines to run on a single server. This reduces the number of physical servers required, leading to cost savings in terms of hardware acquisition, maintenance, power consumption and cooling expenses.
• Resource utilisation: It maximises the utilisation of computing resources. Businesses are able to optimise CPU, memory and storage utilisation ensuring efficient use of available resources, by dynamically allocating these resources based on workload demands.
• Improved agility and flexibility: They provide businesses with agility and flexibility in managing their IT infrastructure. Virtual machines can be easily provisioned, scaled up or down and migrated between physical servers without significant downtime. This flexibility allows businesses to quickly adapt to changing business needs and scale their infrastructure as required.
• Enhanced disaster recovery and business continuity: They often include features like snapshots, backups and replication, making it easier to implement robust disaster recovery and business continuity plans. By taking snapshots or replicating virtual machines, businesses can restore systems quickly in case of failures or disasters, minimising downtime and data loss.
• Simplified management and maintenance: These solutions centralise the management of virtual machines, making it easier to monitor, configure and maintain the IT infrastructure. Tasks like deploying new VMs, applying patches and managing updates can be automated, reducing manual effort and improving efficiency.
• Enhanced security and isolation: They provide better security by isolating applications and processes within their own virtual environments. This isolation helps prevent vulnerabilities or attacks on one VM from affecting others, improving overall system security.
• Testing and development environments: It simplifies the creation and deployment of test and development environments because these machines can be quickly provisioned and cloned, enabling developers to test new applications, configurations or updates without impacting production systems.
• Legacy application support: They allow businesses to run legacy applications on modern hardware and operating systems. By virtualising the environment required for legacy applications, businesses can extend their lifespan and avoid compatibility issues.
• Green IT initiatives: It contributes to energy savings and promotes environmentally friendly practices. By consolidating servers and reducing the physical infrastructure footprint, businesses can lower consumption, reduce e-waste and achieve greener IT operations.

Virtualisation solutions are extremely beneficial for businesses and help them make their operations efficient and cost-effective, in addition to offering flexibility, improved resource allocation, simplified management and enhanced security. These benefits enable organisations to optimise their IT infrastructure to effectively meet the evolving demands of their business.

It is very important to choose a good provider for these types of solutions. Choosing a company or provider who is reputable and experienced and has good reviews is vital in order to successfully implement these solutions in your organisation.
