Description

This curriculum spans the technical and operational demands of managing web hosting environments in a client-facing support role, comparable in scope to a multi-workshop program for IT teams responsible for onboarding, securing, and troubleshooting hosting infrastructure across diverse client environments.

Module 1: Infrastructure Selection and Hosting Environment Evaluation

Select between shared, VPS, and dedicated hosting based on client application requirements, traffic load, and security constraints.
Evaluate hosting provider SLAs for uptime, support response times, and backup frequency when onboarding new clients.
Determine appropriate data center geographic location to minimize latency for end users and comply with data residency regulations.
Assess provider API capabilities for automation of provisioning, monitoring, and scaling tasks.
Compare control panel options (cPanel, Plesk, custom) for usability and integration with existing support tooling.
Validate provider support for required software stacks (e.g., PHP versions, database engines, SSL configurations).

Module 2: Domain and DNS Management in Client Support

Diagnose and resolve domain propagation delays by analyzing TTL settings and DNS cache across global resolvers.
Configure and verify DNS records (A, CNAME, MX, TXT) to support email, website, and third-party service integrations.
Manage domain registration renewals and WHOIS privacy settings to prevent service outages due to expiration.
Transfer domains between registrars while maintaining DNS continuity and minimizing downtime.
Implement DNSSEC where required for clients in regulated industries, balancing security with complexity.
Respond to DNS-based attacks (e.g., cache poisoning, DDoS reflection) with mitigation strategies in coordination with the provider.

Module 3: Server Access, Authentication, and Security Hardening

Enforce SSH key-based authentication and disable password login on Linux servers to reduce brute-force risks.
Configure and audit user roles and permissions in control panels to align with least-privilege principles.
Rotate and manage API keys and FTP credentials across client environments following incident or staff changes.
Implement fail2ban or equivalent tools to automatically block repeated unauthorized access attempts.
Restrict administrative access by IP whitelisting for high-risk servers or compliance-sensitive clients.
Conduct periodic access reviews to deactivate stale accounts and detect unauthorized privilege escalation.

Module 4: Website Deployment, Migration, and Configuration

Plan and execute website migrations between hosting providers with minimal downtime using staging environments.
Verify file and database integrity post-migration by comparing checksums and conducting functional tests.
Configure .htaccess or web server rules to manage redirects, hotlink protection, and URL rewriting.
Deploy SSL/TLS certificates via Let's Encrypt or commercial providers and automate renewal processes.
Optimize PHP settings (memory_limit, max_execution_time) based on application requirements and server resources.
Isolate client applications using suEXEC or containerized environments to prevent cross-site contamination.

Module 5: Performance Monitoring and Troubleshooting

Interpret server resource graphs (CPU, RAM, I/O) to identify resource bottlenecks affecting site performance.
Diagnose slow-loading websites by analyzing server response times, database queries, and script execution.
Use log analysis tools to trace errors in Apache, Nginx, or PHP error logs during outage investigations.
Implement caching layers (OPcache, Redis, Varnish) and validate cache hit ratios for dynamic sites.
Respond to resource abuse alerts by identifying runaway processes or scripts consuming excessive CPU or memory.
Coordinate with upstream providers during network latency or routing issues affecting multiple clients.

Module 6: Backup, Recovery, and Disaster Planning

Configure automated daily backups of files and databases with off-server storage and retention policies.
Test backup restoration procedures quarterly to ensure data integrity and recovery time objectives.
Differentiate between full, incremental, and on-demand backups based on client criticality and storage costs.
Isolate backup systems from primary environments to prevent ransomware propagation.
Document and communicate recovery point (RPO) and recovery time (RTO) expectations to clients.
Respond to data loss incidents by restoring from backups and validating functionality before declaring resolution.

Module 7: Client Communication and Escalation Management

Translate technical server issues into clear, non-technical language for client status updates.
Set realistic resolution timelines when coordinating with third-party hosting providers or data centers.
Document root cause and resolution steps in ticketing systems for audit and knowledge base purposes.
Escalate persistent infrastructure issues to provider support teams with detailed logs and evidence.
Manage client expectations during shared hosting outages beyond internal control.
Conduct post-incident reviews for major outages to improve monitoring and response protocols.

Module 8: Compliance, Governance, and Change Control

Enforce change management procedures for production server modifications, including peer review and scheduling.
Ensure hosting environments meet compliance requirements (e.g., GDPR, HIPAA) through configuration audits.
Document and justify exceptions to standard configurations for legacy or custom client applications.
Apply security patches and kernel updates during maintenance windows with rollback plans.
Maintain version control for server configuration files and deployment scripts.
Conduct quarterly access and configuration reviews to align with organizational security policies.
