Details: This IT project involved building the entire OpenStack foundation 'from scratch' for the Swiss startup CloudLynx, a public IaaS cloud provider. The implementation was based on RedHat distribution of OpenStack (RDO).

Technologies: OpenStack Component: Keystone, Nova, Neutron, Cinder, Swift, Glance, Ceilometer, Heat. GlusterFS as Storage-Backend. KVM as virtualization backend. Foreman, puppet, HAproxy, keepalived, nginx, git, RedHat Directory Server, OTRS, ELK stack, Icinga

Details: Project involved facilitating the spin-off and integration of the Infinion Mobile division into Intel Mobile Communications across approximately 20 global locations. Key activities included migrating and consolidating UNIX user accounts, transitioning applications and licenses, migrating monitoring and alerting services, establishing a system provisioning and configuration infrastructure, and implementing a scalable, highly available VNC-based Linux remote desktop infrastructure for thousands of users.

Technologies: SLES Linux, RHEL Linux, CouchDB, RealVNC, Perl, Python, Shell, scMON, Foreman, puppet, scVenus

Details: Project delivered centralized and standardized management services for Linux workstations across global locations (Europe, USA, Asia). It includes automated and uniform installation management for Linux systems, support for various installation profiles and software repositories at different locations. The project also focuses on secure configuration and patch management with version control and rollback capabilities, alongside active integration into corporate asset management and Active Directory. It offers virtualization support and ensures system qualification as part of its comprehensive approach to managing Linux workstations on a global scale.

Technologies: RHEL Linux, cobbler, puppet, git, subversion, Centrify, yum, shell, python

Details: Design, development, integration, and validation a Linux-based High- Performance Computing (HPC) environment with two independent compute clusters in Europe and the USA, specifically for modeling and simulation. It includes collaborating with a hardware vendor to create the HPC environment, integrating it into the corporate infrastructure in Europe, installing modeling and simulation applications, and establishing standard operating procedures for business users, along with providing training and documentation. Additionally, the project entails setting up a test and development environment, validating the entire HPC setup, and creating a second HPC environment in the USA based on the lessons learned from the European deployment, followed by validation and integration into the corporate landscape in the USA.

Details: Concept, Development and Introduction of resource monitoring and alarming system.

Technologies: scMON, IBM's Tivoli, Peregrine

Details: Integration of complex simulation applications in a CAx environment with numerous users and Linux workstations, including enhancing license monitoring and back charging infrastructure. It includes the development of Perl and Python scripts for automating post-processing and archiving of simulation results, improving automatic installation and update procedures, and enhancing Linux HPC cluster solutions for technical/scientific simulations. The project also manages multiple HPC cluster generations with over 900 nodes, introduces procedures and tools for administrative tasks, integrates new customer sites, provides consulting and support for users and administrators, and handles central application repository operations and administration of various CAE services.
