Virtualisation is the answer to current issues of centralisation of servers infrastructures due to cloud computing projects, the need for a more agile IT dedicated to business needs, and the will to decrease the overall carbon footprint.
As a VMware Enterprise Solution Provider, a Citrix Gold Solution Advisor and a Microsoft Gold Partner, Prolival advice to its clients is to virtualise their IS for servers as well as desktops and applications.
Virtualisation is becoming critical for all levels of IT, from desktop to datacentre. After testing it for quite some time on development environments, more and more companies now use virtualisation to manage critical environments, with cost reductions due to server consolidation.
Many companies intend to extend virtualisation over some basic functions, such as service continuity, post incident reload, tests and development, as well as remote desktop management.
The traditional model « One application = One Server » has reached its limits from a global efficiency point of view, as well as for management, security, continuity and cost issues. IT Directions have been searching for new solutions to try and tackle these challenges.
In a relatively short time, servers virtualisation has become the relevant technology to deal with these issues:
- High optimisation of global infrastructure costs
- An information system less complex and more centralised
- A simplified administration
- A dramatic improvement in capabilities and answer delays from IT services to business needs/li>
- A better use of equipment and a reduction of the IS carbon footprint
- Performance and systems availability optimisation
- Procedures and operation rules standardisation
- New features implementation is easier
Three editors carve up the market amongst themselves :
- VMWare with their vSphere products range
- Citrix with their XenServer Hypervisor
- Microsoft with Hyper –V, integrated to Windows Server 2008
Choosing between these solutions depends on the objectives, the IT infrastructure environment and applications requirements particular to each company. As a partner of these 3 market leaders, Prolival can provide you with the solution best suited to your needs, in complete independence.
VMWare vSphere 5[More]
A pioneer for the virtualisation of PC type servers, VMware offers a complete, reliable, tried and tested solution, with vSphere 5.
More than ever, vSphere and the ever increasing range of applications coming with it, are according to VMware, the operation system of cloud computing and datacentres.
The new release of vSphere, on the market since mid-2011, covers a large range of new features, to expand the range of applications covered by this software suite.
To help companies adopt virtualisation, Microsoft has developed a new generation of server virtualisation solutions, part of Windows Server 2008 R2.
Hyper-V is a reliable and agile virtualisation platform, and provides a unique blend of tools, for the integrated management of physical and virtual resources (Microsoft System Center).
As a part of Windows Server 2008 R2, Hyper-V enables Prolival’s Microsoft certified engineers and consultants, to keep on making good use of their individual skills as well as the community knowledge, while reducing learning phases.
Citrix XenServer is a complete, managed server virtualisation platform built on the powerful Xen hypervisor.
Based on open-source Xen architecture, XenServer is a complete virtual infrastructure solution. It includes a 64-bit hypervisor, to install an unlimited number of host servers and guest virtual machines, with live migration, centralised management and conversion tools.
XenServer is a free product. Clients who have needs for advanced management, availability, integration or automation features can migrate to one of XenServer premium editions, and create more efficient datacentres. Advanced, Enterprise and Platinum editions of Xenserver offer numerous management and automation features: a complete automation of datacentre, advanced management and integration, performance optimisation, etc.
Desktop Virtualisation – VDI (Virtual Desktop Infrastructure)
Desktop virtualisation is adapted from the server virtualisation technology. Complete desktop environments (operating systems and applications) can be run on virtual machines hosted on servers, and accessed via thin clients, completely secure and less bulky.
Thanks to these work environments consolidated in the IT Service, users have access to their usual work environment. These environments become more secure, cheaper and are always available.
This enables IT departments to:
- reduce costs of maintenance and support for workstations
- increase security of workstations
- deploy different complete types of workstations (PC, thin clients, tablets, smartphones…) on centralised servers
- set up very quickly work teams or entire departments
VDI (for Virtual Desktop Infrastructure) is a relatively recent concept but quite a few large companies, among which some of Prolival’s clients, already use it with some success.
VDI is perfectly adapted to the most cost-effective thin clients, each desktop being attributed its own virtual machine on the server, to obtain a reliable, cheap, secure and easy to administer information.
Prolival has had an early interest in the VDI concept, and now integrates the solutions offered by two market leaders:
- Citrix and their XenDesktop solution
- VMware with their View product
According to a study carried out by IDC in July 2011, Citrix and VMware have become two VDI actors that have to be reckoned with, because of their long term vision and the maturity of their offer.
The following diagram represents the positioning, according to IDC, of all the actors of the VDI sphere. Considering the technical capacities of their offer and the strategic vision of the company, IDC reckons that Citrix is the main actor in this market, and should remain so for the next two years.
Citrix XenDesktop optimises the on-demand delivery of applications and virtual desktops, to any user, anywhere, on any device, to meet the mobility and agility requirements of each individual user.
Thanks to XenDesktop, your users can adopt new work styles, such as home office, by integrating IT in their daily life, without losing on productivity when they are away from their office.
XenDesktop also facilitates the transparent use of whatever device they choose as a professional desktop (smartphone, tablet, laptops).
XenDesktop helps you rapidly and cost-effectively adapt to change with fast, flexible virtual desktop delivery, for all your business projects (expansion, offshoring, etc.).
By replacing your former complex and distributed desktop by an easy-to-use, on-demand service, XenDesktop frees you from costs and constraints associated to traditional IT architectures. Management, security and centralised delivery of virtual desktops improve your IT department’s efficiency, while rationalising security and regulatory compliance.
The main purpose of VMware View is to offer the reactivity and availability of cloud computing to desktops and applications. Relying on VMware vSphere, View deploys desktops from a single integrated platform, and is part of your Cloud services strategy:
- Dynamically allocate resources to give a highly reactive and available environment to the users
- Make on-demand desktops services evolve, to quickly answer the company ever changing needs, and ensure a proactive protection against all breaks, planned or not
- Increase control over desktops, applications and data by deploying and managing them as centralised services
- Manage the solution via a single powerful management console. This tool enables to monitor desktops services while giving IT department the opportunity to easily and quickly carry out tasks, which used to be tedious, such as provisioning, updates, and patches deployment
- Manage the desktop components separately for a more agile provisioning, update and deployment
- Easily apply rules, quickly activate or deactivate users from a central console for an optimal reactivity
- Free some time previously dedicated to maintenance for technological innovation
Contrary to traditional PCs, View desktops are not linked to the physical computer. They are hosted on your Cloud and your users can access them whenever they want. VMware View with PCoIP offers the most comprehensive, agile and flexible environment to users around the world, with different network conditions.
Whether you are on or off-line, use basic or 3D applications, LAN or WAN, VMware View provides an optimal productivity for the users of your Information System.
Traditional application deployment has become more and more complex and expensive. IT departments waste a great amount of time to correct and permanently update applications, on hundreds or thousands devices. As a consequence, many desktops are never really up to date.
At the same time, applications and data stored on users’ devices are not secured and can cause conflicts that will slow or cause the desktop to fail.
Virtual application delivery lets IT manage a single instance of each application in an application hub in the datacentre. Applications are then delivered via application streaming to Windows PCs for offline use or run on high-powered servers in the datacentre for online use on any device or operating system.
For application virtualisation, Prolival has chosen Citrix XenApp, as the most tried and tested tool, to help its clients build their architectures.
Citrix XenApp is an on-demand application delivery solution that enables any Windows application to be virtualised, centralised, 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.
Whether application virtualisation or session virtualisation technology is used, XenApp ensures that users receive the highest quality experience through Citrix HDX technology. HDX adapts virtual application delivery and access based on each user’s device, network, and location to ensure an optimal experience.
XenApp enables enterprise-class scalability for any size of business and ensures that virtual application delivery and management is secure by design. XenApp integrates the tools and infrastructure needed to help control, measure, and monitor performance to ensure that service level agreements and corporate security requirements are met.
Application virtualisation technology, session virtualisation technology, and centralised application management gives users direct access to Windows applications from any device, using a Web browser via Citrix Receiver. Citrix Receiver delivers applications to over 30 operating systems.
