LVM, Demystified

I've been a sysadmin for a long time, and part of being a sysadmin is doing more than is humanly possible.

Simple Ways to Add Security to Web Development

As a software developer myself, I have seen developers rushing to finish the feature they are assigned to, with little or no consideration for security in the code—no security guidelines, no coding standards, just a mad dash to finish the feature. Next comes the security review, in which the software obviously fails, and then comes the security-hardening phase. more>>

Alice, the Turtle of the Modern Age

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?

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.
