Study Notes
System Administration and Maintenance
- System administrators are responsible for managing the IT infrastructure of an organization including software, hardware, network, and services.
- They are responsible for installation, setup, implementation, deployment, management, maintenance, monitoring, support, troubleshooting, security, and backup.
IT Infrastructure
- IT infrastructure encompasses the software, hardware, network, and services required for an organization to operate in an enterprise IT environment.
Computer Systems
- A computer system includes computer hardware, software, networking, and internet access.
- Examples: Organisation websites, portals, information data systems
- Input, storage, processing and output are the four basic functions of a computer system.
Server
- A server is a software or machine that provides services to other software or machines.
- Examples: Web server, email server, SSH server
- Server clients request services from a server and in turn, the server responds with these services.
- Server hardware is powerful hardware that needs to run continuously to support server services.
- Examples: Tower Servers, Rack Servers, Blade Servers
How to manage multiple servers?
-
Centralized Management Tools:
- Configuration Management Tools allow administrators to define configurations in code and apply them across multiple servers.
-
Monitoring and Logging:
- Tools monitor server health, performance, and security.
- Logging tracks server activity, which is crucial for troubleshooting issues and identifying security threats.
-
Automation:
- Automating tasks like server provisioning, software updates, and backups reduces manual effort and improves efficiency.
-
Security Management:
- Implementing strong security policies, security software, and regularly updating systems is essential.
-
Backup and Recovery:
- Automated backup solutions ensure regular backup and quick recovery in case of a failure.
- Disaster recovery planning is crucial for minimizing downtime and data loss.
-
Cloud and Hybrid Solutions:
- Cloud platforms like AWS, Azure, and Google Cloud simplify server management with tools like auto-scaling, managed databases, and serverless computing.
- Managing on-premises and cloud servers requires tools supporting hybrid environments.
Cloud Computing
- Cloud computing uses technology to access and use computing resources over the internet instead of owning physical hardware and software on-site.
Benefits of Cloud Computing
- Cost Efficiency: Lower capital expenses and pay-as-you-go models.
- Scalability: Easily scale-up or down based on demand.
- Performance: Cloud providers use upgraded hardware.
- Disaster Recovery and Backup: Built-in backup and recovery solutions.
- Collaboration and Flexibility: Access applications and data from anywhere.
- Security: Robust security measures and tools to protect data and infrastructure.
Data Centers
- Data centers are facilities storing hundreds or thousands of servers.
- Companies with large amounts of data store information in data centers.
- Large companies like Google and Facebook own their data centers.
System Administration
- System administration tasks involve managing organizational policies, IT infrastructure services, user and hardware provisioning, routine maintenance, and troubleshooting issues.
Organizational Policies
- System administrators establish and enforce organizational policies regarding user behavior, software installation, password complexity, internet access, and device security.
IT Infrastructure Services
- System administrators manage IT infrastructure services ensuring they are updated, patched, and compatible with the computer systems within the organization.
User and Hardware Provisioning
- System administrators manage user accounts, provide access to resources, and manage hardware.
- They keep track of hardware lifecycles, including procurement, deployment, maintenance, and retirement.
Routine Maintenance
- System administrators conduct routine maintenance tasks, such as performing regular software updates and security patches.
Troubleshooting and Managing Issues
- System administrators troubleshoot issues, investigate problems, analyze logs, and provide technical support.
- They prioritize issues based on severity and impact.
- System administrators use customer service skills and maintain a bug/ticketing system.
