Linux Strategy

The Core Linux team is following a dynamic strategy that are based on the following basic pillars.

Goal

We enable PSI scientists/staff to focus on their research/work. Based on the resources we are given by management we provide/operate necessary infrastructure, support and services so that people can perform at their best.

We rely on industry standards and professional solutions to ensure the sustainability and robustness of PSI Linux infrastructure. We pursue to find the most simple, maintainable and sustainable solution to our challenges.

Assessment and Planning

Inventory: Conduct an inventory of existing systems and applications using Linux.
Needs Analysis: Identify departments or areas where Linux usage is critical or can be expanded.
Stakeholder Consultation: Engage with departments, scientists, staff and students to understand their Linux requirements and challenges.

Security and Compliance

Action: We work on eliminating/upgrade/... vulnerable systems and services
Resilience: We work to make PSI resilient and robust to cyber threads.
Security Policies: Establish Linux-specific security policies and procedures (e.g., user permissions, firewall settings).
Regular Audits: Conduct regular security audits and vulnerability assessments of Linux systems.
Compliance: Our Linux systems should/must comply with relevant regulatory requirements (e.g., GDPR, HIPAA).

Standardization and Deployment

Linux Distribution: We support a stable and well-supported Linux distribution (currently RHEL) for deployment across the PSI.
Standardize Configurations: Develop standardized configurations for Linux systems to ensure consistency and security.
Automated Deployment: We provide fully automated provisioning and deployment of Linux systems.

Resource Optimization

Virtualization and Containers: Embrace virtualization and containerization technologies (e.g., Docker, Kubernetes) to optimize resource utilization.
Energy Efficiency: Implement power management strategies for Linux systems to enhance energy efficiency.

Monitoring and Performance Tuning

Monitoring Tools: Deploy monitoring tools to track Linux system performance and health.
Performance Optimization: Regularly optimize Linux systems for performance based on monitoring data.

Training and Support

Training: Organize training sessions and workshops to enhance Linux skills within PSI.
Documentation: Maintain comprehensive documentation and guides for Linux usage and troubleshooting.
User Support: Provide responsive user support for Linux-related issues and queries.

Backup and Disaster Recovery

Backup Solutions: We rely and implement robust backup solutions for critical Linux data and configurations. (provided by other PSI teams)
Disaster Recovery Plans: Develop disaster recovery plans specifically tailored for Linux systems.

Continual Improvement

Feedback Loop: Establish a feedback loop to gather insights from users and stakeholders for continuous improvement.
Periodic Reviews: Conduct periodic reviews of our strategy and services to adapt to evolving needs and technological advancements.

Misc

Engagement in Communities: Encourage participation in open source communities and projects relevant to our needs.
Contribution: Foster a culture of contributing back to the open source ecosystem.
Encourage Innovation: Promote Linux-based research and development initiatives within PSI.
Partnerships: Explore partnerships with industry and other academic institutions for collaborative Linux projects.
