What Differentiates Nixu DDI Software Appliance?
A
Software Appliance is a productized server stack hardened and optimized for a specific task. It contains all software components
required to jump-start x86-based machines in just minutes, including an automated installation of built-in JeOS (Just enough Operating System).
Distributed electronically as an ISO installation media,
Nixu DDI software appliances can be run as virtual machines in VMware and Citrix XenServer environments,
or on native x86-based RHEL-compliant servers.
Benefits Over Traditional Software
Ease of Deployment
With built-in operating system and pre-packaged software modules, you do not have to worry about library dependencies, installation,
hardening of the operating system or other system-side tasks. Our ISO image includes and automatically installs every piece of software needed, including
a Linux-based JeOS. So, all you have to do is to provide a virtualized runtime environment or a clean x86-based server (rack-mount, blade) for the
installation and the rest is taken care of.
Simplified Maintenance
Because we have productized the entire software stack, Nixu software appliances include patch management features that automate the entire
software update process. In this respect, software appliances are no different from traditional hardware-based server appliances, offering lower
OPEX than traditional software-based DNS, DHCP and IPAM server implementations that are maintained manually.
Improved Security
The productized and hardened server stack included in Nixu software appliances has been designed by adhering to Defense in Depth,
Least Privilege and Default Deny principles. This makes Nixu DDI more secure than most DNS, DHCP and IPAM deployments running traditional software,
because the entire server stack has been optimized at the factory. Additionally, Nixu software appliances also come with built-in Intrusion Detection
and Prevention capabilities not found in other mainstream DNS, DHCP and IPAM server implementations.
Benefits Over Hardware-Based Server Appliances
Hardware Cannot Be Virtualized
Companies coming from hardware appliance background have typically designed their product and solution architectures for closed computing environments
optimized for a specific piece of hardware. While many DDI companies have made attempts to introduce virtual appliance versions of their products,
they are plagued with performance, scalability and resiliency issues, triggering claims that network services should not be virtualized.
Yet the root cause for these problems is that DDI solutions designed for closed computing environments running on native hardware are simply not
suited for server virtualization.
Because software appliances do not carry this package, they offer superior level of performance,
scalability and resiliency in virtualized computing environments.
Better Value, More Freedom
Most hardware-based server appliances run generic hardware that provides no reliability or performance advantage over general-purpose servers
from Hewlett-Packard, Dell, IBM, Fujitsu and the like. In other words, many hardware appliance vendors are selling you commodity hardware at an
inflated price, without transparent cost-structure that would help you in optimizing your operating expense (OPEX) and to really know how much you
are paying for the hardware.
But perhaps more importantly, by running software appliances instead of hardware-based DDI products, you can freely
use the platform you have standardized on. ESXi, HP blade, rack-mount Dell – you’re free to choose.
To make an installation, simply download the Nixu ISO of your choice and use it to jump-start a new machine.
A new server instance with hardened Linux OS will be up and running in just minutes.
