Setting Up Virtual Security Zones in a Linux Cluster

The Distributed Security Infrastructure lets you create disjoint virtual security zones on a physical Linux cluster.
Conclusion

We have shown a practical solution for sharing a cluster securely among different applications belonging to different users. The DSI Project allows users to create disjoint security zones for each application in the cluster easily. Once DSI is installed on the cluster, the effort needed to create a new security zone for new applications scales down to setting appropriate ScIDs to binaries and including corresponding rules in the DSP file. Source code modification is not required and probably would be impossible anyway.

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.
