Compare VPN-based access wid direct HTTPS exposure, an understand authentication, access control, an logging fi each way.
User access patterns and threat modelingSite‑to‑site and client VPN design optionsDirect HTTPS exposure and hardeningAccess control, SSO, and audit loggingLesson 4High-availability an scaling considerations fi future growth an optional storage expansion strategiesPlan fi high availability an future scaling of yuh Nextcloud setup. Check vertical vs horizontal scaling, clustering options, an storage expansion strategies so yuh can grow capacity widout big redesigns.
Vertical vs horizontal scaling trade‑offsLoad balancers and application clusteringScaling database and cache componentsExpanding storage pools and migration pathsLesson 5Network design: DNS naming conventions, internal vs external records, split-horizon DNSDesign a DNS layout dat cleanly separates internal an external views fi Nextcloud. Learn naming conventions, split-horizon DNS, an how fi avoid conflicts, leaks, an certificate issues when exposing services securely.
Choosing consistent DNS names and subdomainsInternal vs external DNS zones and recordsImplementing split‑horizon DNS safelyDNS considerations for TLS and certificatesLesson 6Ports an firewall planning: required ports, NAT, an secure exposure of servicesPlan firewall rules an port exposure fi a secure Nextcloud deployment. Identify required ports, design NAT an port forwarding, an decide how fi publish web, database, an admin interfaces while minimizing attack surface.
Required ports for HTTP, HTTPS, and adminDesigning firewall rules and default policiesNAT, port forwarding, and DMZ placementRestricting admin and database network accessLesson 7Choosing web server: Apache vs Nginx configuration differences an performance/compatibility wid NextcloudDecide between Apache an Nginx as di web server fi Nextcloud. Compare configuration models, performance, an compatibility, an learn how fi enable HTTPS, caching, an important security headers on each platform.

Compare HDD, SATA SSD, an NVMe, choose RAID levels, an evaluate file systems to balance cost, speed, an resilience fi Nextcloud data an database workloads.
Workload patterns for Nextcloud file storageComparing HDD, SATA SSD, and NVMe optionsRAID levels for redundancy and performanceChoosing file systems and mount optionsLesson 10Sizing CPU, RAM, an storage fi 25 users an 2 TB first-year growth wid headroomFigure out CPU, RAM, an storage needs fi bout 25 users wid 2 TB expected growth in di first year. Learn how fi size fi peak load, add extra space fi bursts, an plan expansion widout messing up existing Nextcloud services.
