UNIX Migration to Linux

Enterprises consider migrating from their existing IT systems for many reasons. Their hardware might be getting old and needs to be refreshed to increase application performance, power, speed, energy efficiency. Or they must reduce costs in general and be able to improve flexibility to changes in business demands. For these reasons and more, UNIX migration to Linux is becoming a popular move.

Consolidation

With the newer, more powerful servers x86 (multi-core), companies are also consolidating and thereby reducing their footprint and TCO.

Virtualization

You might be virtualizing your environment and need to be able to mix and match operating systems on a single server to increase flexibility, improve utilization, dynamically allocate workloads based on usage and demand thereby lay the foundation for private cloud computing.

Potential drivers for considering a migration:

• Deploy standards based technologies to decrease costs, decrease complexity, or increase compliance
• Reduce vendor lock-in and increase the choice of hardware, applications, and peripherals available to your IT efforts
• Move to commodity platforms without excessive retraining or the need to replace IT staff
• A mandate to adopt open standards-based platforms to quickly adapt to change and modernize the IT infrastructure and be ready when considering virtual and cloud computing in the near future.

Why Linux?

Proprietary UNIX makes you increasingly vulnerable to cost increases and limits your options. This is especially the case with AIX, as it runs only on POWER processors. Therefore customers have begun considering Linux and even Windows Server on x86. Linux provides the robustness and scalability of AIX and is supported on more platforms than Windows Server and in some cases Windows Server has not been able to scale as high or provide the performance that IBM users are accustomed to on AIX/POWER servers.

Why not Migrate to Linux?

But the key question is, if you can easily migrate your workloads onto a platform that is just as capable as your current AIX system while improving your responsiveness, flexibility, lowering your costs, and standardizing on an operating system that supports your evolution from physical to virtual and cloud computing, why wouldn’t you?
