One response to “ActiveState Stackato Now Supports Private PaaS on HP Cloud Services”

  1. Diane Mueller

    As the only Secure Multi-tenant PaaS, Stackato is easily differentiated from other Cloud Foundry based offerings. Early on in the development of Stackato, ActiveState made the decision to extend Cloud Foundry to take advantage of Linux technologies to provide better security.

    The Stackato team has extended the Cloud Foundry architecture with secure lxc containerization, ssh support, and added application lifecycle support features to ensure exisiting applications can deploy as easily as new/greenfield apps

    Stackato creates isolated, lightweight containers known as “lxc containers,”. Conceptually, the containers are built atop several Linux technologies which provide each guest-application container with a segregated file system with web and ssh services.

    The containers are protected from each other: a guest application in one container cannot read files owned by another container, or kill its tasks. With the Stackato-container approach, the outside world can still reach web servers and ssh servers on the containers and, more importantly, the hosting PaaS can protect its key files from guest applications and users in the containers.

    The containers effectively allow Stackato to partition the resources into isolated groups to better balance conflicting demands on resource usage between the isolated groups. Stackato’s innovative containerization approach has the dual benefits of running applications on a seemingly separate machine while still leveraging many of the underlying resources. As far as the guest application is aware, the PaaS has provided a private Playground.

    The architecture makes Private Cloud even more “private.”

    For enterprises, the operational and security advantages of sharing these resources while isolating the guest applications can also lead to significantly lower overhead than true virtualization.
