Study Notes

Role of System Administrators

Support user productivity.
Balance individual needs with the benefit of the whole community.
Manage a global network of machines and organizations.

Challenges of Global Connectivity

Interconnectedness: Being connected to the internet means interacting with all other connected computers.
Security and Privacy: Consider security and privacy implications of global connectivity.

The Complexity of System Administration

Hardware: System administration involves hardware, software, user support, diagnosis, repair, and prevention.
Software: It requires broad skills in technical, administrative, and socio-psychological areas.
User Support: System administrators must be able to troubleshoot complex issues and provide effective support to users.

Terminology in System Administration

System Administration: Traditionally involves managing computers (mainframes, UNIX systems), networked or not.
Network Administration: Focuses on managing network infrastructure (routers, switches).

Applying Technology in an Environment

Hardware Configurations: Building hardware configurations.
Software Systems: Configuring software systems.
Compatibility: Ensuring hardware-software compatibility.
Environmental Constraints:
- Hardware: Requires power, climate control, and standard conformance.
- Software: Depends on hardware and operating systems but is less constrained physically.

Purpose-Driven Technology

Business Goals: Technology decisions should align with business or operational goals.
Action Guidance: Guides actions and decisions in system administration.

The Human Role in Systems

System administration requires patience, understanding, and experience.
Administrators act as doctors, psychologists, and mechanics, managing crises with limited resources.

Ethical Issues in System Administration

Ethical considerations must guide decisions in system administration.
Protecting individual rights while maximizing productivity and minimizing costs is crucial.

Debate on Scientiﬁc Nature

Lack of Experimental Data: System administration lacks the controlled experiments common to traditional sciences.
Potential for Scientific Approach: System administration can adopt a more scientific approach through rigorous analysis and data-driven decision-making.

Market and Academic Recognition

Growing Market: The market for system administration consulting is expanding.
Career in Engineering: System administration is increasingly recognized as an engineering career.

The Challenges of System Administration

Network Design: Designing efficient and logical networks is a key challenge.
Scalable Deployment: Deploying scalable machines and services is crucial for growth.
Security and User Comfort: Planning for security, user comfort, and error resolution is essential.
Knowledge Management: Managing vast and evolving knowledge is a constant challenge.

Common Practice vs. Good Practice

Best Practice Skepticism: Questioning the rationale behind widely accepted practices is important.
Informed Skepticism: Constant re-evaluation of practices is essential for adaptation.

Bugs and Emergent Phenomena

Reality of Bugs: Operating systems and software are full of bugs.
Creativity: Working around bugs requires creativity and problem-solving skills.
Sources of Bugs: Poor quality control, software clashes, cosmic rays, viruses, etc.

Meta Principles of System Administration

Policy is the Foundation: System administration starts with a clear policy outlining goals and tolerances.
Predictability: Aim for a predictable system to ensure reliability and security.
Scalability: Systems should grow in accordance with policy, maintaining predictability even as they scale.
