Glue 2.0 - DIT managed Linux support


What is Glue?

Like Microsoft Endpoint Configuration Management (MECM) or JAMF for Apple device configuration management, DIT’s Glue provides configuration management for Red Hat Enterprise Linux (RHEL).  Glue isn’t a singular commercial off-the-shelf (COTS) product but comprises commercial and open-source software, scripts, account management, and processes.  Glue has been going through a major revision over the past few years.  Most of the backend systems that support RHEL 6 (Old Glue v1.5) are being retired, and RHEL 6 itself is being retired and replaced with newer tools and processes that support RHEL 7 and 8 (New Glue v2.0).

 

What Linux support can DIT offer?

License renewals

Unmanaged Servers

Managed Servers

DIT has deprecated support for RHEL 6 and Glue v1.5, and currently provides support for Red Hat Enterprise Linux (RHEL) versions 7 and 8 with Glue v2.0.

Glue v1.5

This configuration management solution creates an RHEL 6 image that images servers with rsync, installing the base OS and latest patches.  AFS played an important role as it is where configuration files are stored, often referred to as the config tree.  Specific configurations, such as running services, printers, users who are allowed to log in, become root, and mounts, are stored in the Config tree. Storing the configurations centrally, and not on the local machine, allows for quicker recovery times and better scaling.

Glue v2.0

Glue v2.0 is available now to everyone who wants to utilize DIT’s managed enterprise Linux solution.  Glue v2.0 is drastically different from the previous solution and utilizes the following technology:

Partially managed (customer-owned)

AWS Virtual Server Hosting (AWS VSH)

AWS VSH provides server owners configuration management by utilizing Glue v2.0, DIT’s managed enterprise Linux environment.  Servers will be managed/configured like all other DIT-owned servers. The server owners will be responsible for reboots for patch installation, backups, additional software installation, and other tasks related to system administration, as discussed in this article.   Several IT Support articles also discuss billing and the EC2 Compute FAQ.  Additional Red Hat software/updates are available in the Red Hat Software Collection (RHSCL) that server owners may install.  DIT recommends only using software from the RHSCL since these updates will be installed via patching versus software repositories not backed by vendor support.  Administrators installing software from the RHSCL, or other packages, are responsible for installation, resolving dependencies, and troubleshooting. Non-vendor (Red Hat) software must be monitored by the administrator installing the package and updated.
