Introducing Linux into the Enterprise

How to save money by using Linux as a platform for server consolidation.
What to Do with All the Extra Time?

So now it's time for some of those cool tricks I promised. Would you believe me if I said that you can build a complete Windows 2000 or NT 4.0 server in just a few minutes under GSX? Or, how about multiple servers at the same time in under an hour? Here's how it works. The first build of an operating systems in GSX takes the usual amount of time to complete and configure, but if you need multiple servers with the same base build or similar configuration, you can copy the files created after the initial build to subsequent virtual server directories. Simply create the new servers in the web admin console as before, copy the server files, then change a few lines of information (such as server name and the pointers to the new server's disk files, *.dsk) in a config file (i.e., win2000.cfg). After that, power on the new servers and change their IP address, machine name, etc. It's a good idea to tarball the files, name them appropriately and copy them off to a DLT, CD burner, etc. Now pat yourself on the back because you built multiple identical servers in minutes. At this point you can customize your servers to be SQL, web, e-mail, etc.

In addition, GSX gives you a fast way to build multiple servers and a much quicker way to recover from a serious crash. In the event of an unrecoverable OS failure (you were backing up, weren't you?), rather than having to rebuild the OS and then restore your data, copy the server files from the tarballs that you created. Now restore your data and calmly say to yourself, "life is really, really good".

So there you have it--a high-powered Linux server that can host as many virtual servers as you have the memory and the horsepower for. I encourage you to visit the VMware site and check out the GSX Server product (there is also an ESX Server product that runs directly on top of the hardware--no OS), and give the 30-day demo a spin. For our purposes, Linux combined with VMware's GSX Server have been a real blessing.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
