Why use Citrix in a Virtual Environment?
Organisations today face increasing pressure to deliver business applications an
d data from
anywhere, especially as trends such as globalisation, mobility, offshoring and home-based working.
Running a business today – whether a mid-sized company or a worldwide enterprise – requires you
to provide mission-critical applications to your users so they can be productive in their jobs. This
statement is deceptively simple: the hard reality is that the landscape of business has changed.
Traditional networking, security, and management solutions can only take you so far and eventually
every company experiences the same problems: application performance goes down, management
costs and complexity go up, and security risks become extremely difficult to contain.
The best access experience
Citrix Access Gateway delivers the same rich desktop experience users enjoy when connected to the
local network. Always-on access automatically and seamlessly reconnects users when they change
locations and devices or lose connectivity, reducing frustration and improving productivity. A Webbased
landing page delivers quick and easy access to key resources, and users can choose from
a wide variety of devices, including mobile devices.
Why Virtualisation?
ESX Server are “bare metal” hypervisors that partition physical server in multiple virtual machines. Each virtual machine represents a complete system, with processors, memory, networking, stoarage and BIOS.
- Multiple virtual machines can share physical resources and run side by side on the same server.
- Operating systems and applications can run unmodified in virtual machines.
- Hosted virtual machines deliver better availability than dedicated servers because they can be migrated from one server to another with no downtime
- Hosted virtual machines are easier to scale without purchasing additional hardware, and more secure because each virtual machine is completely abstracted from the hardware and isolated from other virtual machines
- Outstanding application performance over any network
- Continuous availability and reliable, fast application performance
- One interface, one logon, one great experience
