will be the new face of open source support
As more systems integrators start using open source components for creating business solutions, they're becoming the source for support. Frankly, executives don't care about the underlying technology as much as they do about who they're going to call when there's a problem and whether the systems integrator will be able to help them. From a change perspective, it's generally more economical and reliable for companies to outsource the support for open source applications. As adoption of open source applications increases, more and more vendors are offering support for these open source applications, and the support contracts simply follow the implementation contracts.
server virtualization services
Both Linux distributions utilize Xen for their virtualization strategies, though there are differences. Xen has been available on Novell's SUSE for over a year now, while Red Hat just stepped to the plate recently. Xen virtualization is widely considered to provide the best performance, and fully virtualized environments allow for more guest instances. Xen, a hypervisor, which can execute several virtual machines on one piece of hardware, is based on paravirtualization. This virtualization strategy already has the support of many of the largest vendors.
and Red Hat Linux overview
In terms of reliability, the general consensus is that Linux is comparable to many commercial Unix systems but more reliable than most desktop-oriented operating systems. This is especially true if you rely on your computer system to stay up because it is a Web server or a file server. (You don't have to reboot every time you change something).
* Because you can get the source code, you are free to change any part of the Linux system, along with any open source software that comes with it, in any way that you choose. Unlike many self-contained commercial products, open source software tends to be built in pieces that are meant to interact with other pieces, so you are free to mix and match components to suit your tastes. As I mentioned earlier, Linux is a culture that encourages interoperability. For example, if you don't like a window manager, you can plug in a different one because so many were built to operate within the same framework.
* All-in-One Guides: Linux Migration Project Guide
Most larger businesses today have enterprise resource planning (ERP) applications running on some kind of Unix platform and would like to take advantage of the many benefits offered by running their ERP applications on Linux. As you should already know, some of the advantages of migrating to Linux are cost, flexibility, scalability and enhanced security features. If offered on the right platform, Linux can scale even better than some Unix flavors, while offering more flexibility in terms of hardware and software options. The assessment phase is a key offering that you will need to provide to your clients. You'll have to go on-site and determine exactly what it is that they have and where they'd like to be. Your job is taking them there.
Linux SUSE 10
The most important part of getting Linux SUSE 10 up and running is installing the system. Unfortunately, this is also where most users encounter problems because of differences between the types of information that you need to know when installing Linux versus Windows. This chapter demystifies the process by helping you through the installation, pointing out any stumbling blocks that you may hit upon, and offering suggestions for resolving them.
partition on IBM POWER (LoP) services and best practices
If you're going to migrate to LoP, you must understand the critical differences between your source and target platforms. Ensure applications are supported. The three big problems are: Endianness or byte ordering, data type length in 32- and 64-bit environments and data alignment differences in the architectures. If you're going to port, you must study these areas in detail. The number of tested, native applications available for LoP just exceeded the 2,500 mark. Here is a link that shows you the list of all applications currently migrated to LoP.
