VIRTUALISATION


Virtualisation has become one of the most talked-about technologies in recent years because it breaks the “hard-coded” link between hardware and software, allowing individual computing components to be dynamically combined and reassembled for maximum efficiency and agility.

Citrix has long been the leading provider of virtualisation technologies at the user tier of computing with products that deliver mission-critical applications to end users with the best performance, security and cost savings.

Citrix is the only company that provides end-to-end solution for virtualising applications, desktops and datacentres. Together with end-to-end WAN optimisation solutions (NetScaler and Branch Repeater appliances) for IP-based WANs, Citrix offers a complete solution for small, medium and large companies to deliver applications and desktops every user across the globe.

Server Virtualisation

Citrix XenServer is a complete, managed server virtualisation platform. Xen technology is widely acknowledged as the fastest and most secure virtualisation software in the industry. XenServer is designed for efficient management of Windows and Linux virtual servers and delivers cost-effective server consolidation and business continuity.

Server virtualisation enables one physical server to support multiple workloads simultaneously by decoupling workloads—consisting of an operating system, application set and configuration—from the physical computing platform and running them in separate virtual machines (VMs). Benefits include isolation (running multiple workloads safely and securely on a single computing platform) and workload portability (the ability to move workloads across different physical computing platforms).

Advanced server virtualisation platforms can even migrate actively running workloads across physical servers, allowing the workload to float across a pool of physical computing resources, which enables IT departments to maximize available computing resources, reduce costs and deliver applications to users reliably and effectively.

Desktop Virtualisation

Citrix XenDesktop lets you deliver on-demand virtual desktop and applications anywhere your users work, anywhere your business takes you, to any type of device, bringing unprecedented flexibility and mobility to your workforce. XenDesktop unlocks the full productivity and creativity of every worker while helping the entire organisation adapt rapidly to new challenges and opportunities.

Desktop virtualisation abstracts the desktop workload—including the operating system and applications—from the desktop hardware. Combined with server virtualisation, multiple desktops can be secured and run on the same host server in a datacentre completely isolated from one another. This desktop computing model is generally referred to as virtual desktop infrastructure (VDI).

XenDesktop is a desktop virtualisation and VDI solution that delivers a complete Windows desktop experience as an on-demand service to any user, anywhere. XenDesktop can quickly and securely deliver individual applications or complete desktops while providing a high-definition user experience.

Citrix FlexCast delivery technology, included in XenDesktop, enables IT to deliver any type of virtual desktop, on any device. With XenDesktop, IT can manage single instances of each OS, application and user profile and dynamically assemble them which increase business agility and simplify desktop management.

Unlike first-generation VDI solutions that were applicable only to a narrow set of users, XenDesktop with FlexCast is the first product in the industry to support every desktop virtualisation model in a single, integrated solution. This approach extends the benefits of virtualisation to every employee in the enterprise. With the full integration of XenApp functionality, customers can deliver on-demand applications as a seamless part of their overall desktop management strategy.

Citrix XenDesktop offers a next-generation, user-centric desktop virtualisation solution that provides a complete system for desktop delivery. For IT departments, XenDesktop greatly simplifies the desktop lifecycle management process and drives down the cost of desktop ownership by separating the delivery of the desktop operating system from applications and user settings.

Application Virtualisation

Citrix XenApp is an on-demand application delivery solution that enables any Windows application to be virtualized, centralized, and managed in the datacentre and instantly delivered as a service to users anywhere on any device. In use by over 100 million users worldwide, XenApp delivers on the promise of proven application compatibility.

Compared to traditional application deployment technology, virtual application delivery with XenApp enables organisations to improve application management by:

  • Centralizing applications in the datacentre to reduce costs.

  • Controlling and encrypting access to data and applications to improve security.

  •  Delivering applications instantly to users anywhere.

Application virtualisation is a technique for isolating an application from the underlying system and allows IT to run the application on a server in the datacentre but display the application interface on the user’s desktop, regardless of the underlying platform or operating system.

XenApp is a Microsoft Windows application delivery system that manages and virtualizes all applications in the datacentre and delivers them on demand to office, task and mobile users for optimal application performance and flexible delivery. These applications either run centrally in the datacentre or are streamed to the user’s preferred device.

A single copy of the application is managed centrally, reducing support and maintenance costs by as much as 40%. With more than 100 million users and 99% of the Fortune global 500 as customers, XenApp is the leader in delivering Windows-based applications with the best performance, security and cost savings.

Storage Virtualisation

You may want to choose storage devices based on value for money, performance or scalability. But all too often integration issues tie you into buying from a single supplier. To address this issue, and simplify management, Allcom offers leading storage virtualisation solutions from NetApp and IBM.

The storage virtualisation approach enables a single point of entry to storage resources, irrespective of your back-end infrastructure. You can also add new hardware from multiple vendors seamlessly as your storage needs increase, so you can make hardware purchasing decisions based on performance and value for money – rather than brand alone.

In addition to these benefits, storage virtualisation solutions from Allcom help you increase hardware utilisation and reduce your management costs. What’s more, they support data replication across the entire storage environment, helping you ensure business continuity and streamline critical backup processes.

Allcom was one of the industry’s first providers of storage consolidation solutions and our people have accumulated unparalleled skills and experience in the field. With a tried-and-tested delivery approach, Allcom can ensure success for your storage virtualisation projects – irrespective of their scale or complexity.

Allcom can help you achieve the most out of storage virtualisation including:

  • Information governance

  • Easily scaled storage infrastructure

  • More efficient use of your current assets by aggregating and pooling disparate storage infrastructures

  • Significant reduction in operational costs

  • Better performance

  • Easier migrations and consolidations.
