Sigma distributes the leading edge virtualisation software to manage, secure and enhance existing systems to save costs for your customers.

With a virtualisation layer in the middle of your hardware and software, the system behaves normally, but also enables you to:

  • Use your chosen operating system on your hardware of choice.
  • Use a software application to divide one physical server into multiple isolated virtual environments.

For a business, the virtualisation allows multiple employees to all run off one powerful piece of hardware but the software believes it is still running on a dedicated server.

Top Ten Reasons

10 reasons to virtualise!


  • 1 Make utility bills history
    Reducing the number of physical servers you run saves huge amounts of money on both running the machines and cooling the server room.
  •  
  • 2 Save space
    Square footage for office space is not cheap, so why allocate it to unnecessary server racks? Virtual machines don't take up as much room...
  •  
  • 3 Reduce downtime
    Today, server virtualisation platforms offer capabilities such as live migration, storage migration and distributed resource scheduling. Being able to quickly move virtual machines between servers is a huge benefit of virtualisation.
  •  
  • 4 Keep legacy applications longer
    Legacy apps are hard to give up - the fear alone of trying to migrate them is enough to put off the bravest IT teams. So if you have these apps but they aren't supported on modern operating systems, won't run on new hardware or there's no one around you can trust to migrate it, virtually isolating means you can extend its life and finally get rid of the dusty old hardware.
  •  
  • 5 Disaster recovery
    DR sites no longer need an identical hardware environment, so you can buy cheaper kit as it rarely gets used and finally most server virtualisation platforms have automated failover software so you're already on top of the situation when disaster strikes.
  • 6 Create simple test environments
    Save yourself the time, effort and expense of physically setting up a new environment for testing- just create a virtual lab and allocate resources accordingly!
  •  
  • 7 Minimalise set up time
    Set up a new virtual machine in minutes by simply cloning an existing machine rather than hours of putting together a physical environment and then installing all the software... again.
  •  
  • 8 Fully utilised servers
    We're no longer bound by the one app/one server model to isolate our applications. Server virtualisation isolates, but removes the need for one app/one server, so you're fully using your resources by consolidating your virtual machines.
  •  
  • 9 Who needs hardware anyway?
    Why not get rid of your hardware altogether? You're already going down this path if you're virtualising, so as the technology in the cloud gets stronger, you're already perfectly placed to take a skydive and land in your new cloud hosting environment. Think of all the space you'll create and costs you'll eliminate!
  •  
  • 10 Common Management Interface
    Being able to have your servers in a single application is great, but the ability to control those servers from a single interface is even better. Virtualisation offers access to virtual machine hardware, consoles and storage, leaving your systems readily available.

Cloud Servers vs Dedicated Servers

Cloud Server

Cloud Servers

    Increased mobility
    Pay as you use
  •  
  • CONS
    Bandwidth is limited
    SQL Storage is expensive
    Lower Performance in some instances
    Expensive disk space
    Lack of control

Dedicated Server

Dedicated Servers

  • PROS
    Full control
    Room to grow
    Cheaper bandwidth
    Cheap disk space
    High Performance
  •  
  • CONS
    Always paying for maximum power
    Exposed to hardware failures
    Rigid specs
    Limited physical disk space
    More requirement for configuration and management
Server Management Software

Server Management Software

As there are multiple different kinds of servers - File, Network, Print, Database, there are equally as many different variations of server management software available. Solutions range from configuration, roles management, status monitoring, migrations, storage and many more. Check out our top vendors who offer solutions to meet your customers' needs.
