Server
Ubuntu Server Edition
Lean, fast and powerful, Ubuntu Server delivers services reliably, predictably and economically – and it easily integrates with your existing infrastructure.
Why use Ubuntu Server?
Easy integration
Ubuntu Server mixes effortlessly with Ubuntu, Windows or Mac OS environments. All clients can share authentication, swap files and access services, while Open LDAP, Likewise-Open and PAM authentication come as standard.
Virtualise everything
Virtualise your servers with Ubuntu Server and KVM. Use a secure, lean version of Ubuntu as a guest operating system for your application and create virtual machine images in minutes. KVM, Xen, VMWare and LXC are all supported.
EC2 or UEC
Build flexible computing environments in your own infrastructure with Ubuntu Enterprise Cloud (UEC) or deploy to Amazon EC2 using Ubuntu Server Edition images.
Built-in security
Tighten security by defining access to specific users and programs. Uncomplicated firewall technology makes access secure yet simple, while a home and private directory encryption service adds another layer of security.
Minimise administration
Simplify operations like start-up, shut-down and package management with single commands. Deploy services in seconds or set up industry-standard mail, virtualisation, Java applications or database servers in minutes.
