Conversion of a legacy version control infrastructure into a museum environment
Project Challenge
Due to acquisition customer inherited a large version control environment based on IBM Rational ClearCase©. The total amount of design data was nearly 10 TB split into ~2,000 repositories, in some cases with a 15+ year history and a high degree of geographical distribution. The infrastructure was mainly based on physical Sun Microsystems servers. Although most of the projects already ended the customer was still facing maintenance obligations for the designs (10 or more years after tape-out). The decision was taken not to migrate the legacy projects into a new environment (SVN or Git) but to consolidate the data into a central so called „museum“ that allow immediate but limited access by designers on an ad-hoc base to fulfil the maintenance requirements. Some of the sites involved have been running the legacy instances for a while without a designated administrator.
Solution Provided
- Analysis of the different sites and the replication scenarios of the repositories.
- Installation and configuration of a new museum environment based on virtual Linux servers.
- Support the ramp up of a VDI based infrastructure for designers to work on Linux or Windows clients.
- Consolidate the replicated data set into the museum environment in a controlled and site-by-site approach.
- Support the adjustment of connected environments (for example build environments for projects) to work with the museum infrastructure.
- Provide on-going support for the museum environment and end-users during and after the consolidation.
Value Delivered
- Saving significant costs by eliminating 5 physical legacy server clusters (4 Sun Microsystems and 1 Windows environment).
- Reduced the number of licenses by 2/3rd with a significant reduction in annual support cost for IBM Rational ClearCase.
- A standardized environment for remote use is now available supporting all necessary tools for maintenance work in design projects.
Project Challenge
- Huge version control environment, based on IBM Rational ClearCase©.
- Approx. 10 TB design data, ~2.000 repositories, up to 15+ year history
- High degree of geographical distribution
- Consolidation of data into a central "museum" for ad-hoc maintenance requirements
- Partially no designated administrators
Value Delivered
- Significant cost savings - shut-down of 5 physical legacy server clusters
- Significant reductions of licence maintenance
- Standardized environment for remote access
- Comprehensive maintenance tool support

Cloud-based developer platform
Cloud-based developer platform
Project Challenge
The developer platform of a large business unit (~ 200 developers) should be accessible for other business units. The extension project serves as model for a cross-company cloud-based developer platform (~ 20.000 employees with a high percentage of external IT specialists). This implied to enhance the access of a single-site platform in southern Germany for teams throughout Europe while ensuring compliance:
- Ensuring segregation enforced by legal requirements – data from one nation may not be exposed to another project.
- Building up a support desk that is able to „onboard project“ within a few days, targeting a few hours.
- Integration of external services that new teams (from other business units) bring in.
- Starting a local cloud service and moving services into it.
- Stabilizing a VMware-based sandbox environment for regular updates and enforced OS hardening.
- Migration of several project workspaces from individual team instances to the IT managed tool stack.
Solution Provided
- Definition of a role-group concept to be pushed through Crowd to all platform applications ensuring segregation.
- „Onboarding project“ concept including questionnaires that allow for base applications like JIRA / Confluence / Bitbucket to be handled in minutes by the service desk.
- Independence from back-office VMware provisioning by moving per-project services (e.g. Jenkins, Sonarqube) into Kubernetes clusters.
- Integration of the self-managed Kubernetes clusters for general one shot slave usage by teams and supporting them to change their builds.
- Migration / integration support for existing Jenkins jobs and source code in Subversion, ClearCase.
- Support for company strategy group with their global hybrid cloud (was OpenShift, to be AzureStack).
- Going multi-site to help teams in other nations, including Nexus services with proxy entries spread over sites.
- Starting an automated test suite to support regular (at least monthly) updates of all developer support application servers.
- Analysis, planning and automated merges of data from team instances using Mitlas, the service for accelerated Atlassian tool consolidation on a central data center instance without business interrupts.
Value Delivered
