Hosting Models

Lessons in This Module

1. Lesson 1

   What Happens When You Deploy an Application

   Deployment turns a tested version of software and its configuration into a running service reachable by its intended users. Learn the founder decision, practical evidence, and warning signs that matter.

2. Lesson 2

   Domains, DNS, and SSL

   A domain is the human-readable address, DNS directs it to services, and SSL/TLS encrypts and authenticates connections. Learn the founder decision, practical evidence, and warning signs that matter.

3. Lesson 3

   Development, Staging, and Production

   Development supports active building, staging provides a production-like review environment, and production serves real users and data. Learn the founder decision, practical evidence, and warning signs that matter.

4. Lesson 4

   Managed Platforms and Shared Hosting

   Managed platforms operate much of the application runtime, while shared hosting provides constrained resources and a standard control panel across many customers. Learn the founder decision, practical evidence, and warning signs that matter.

5. Lesson 5

   Shared Hosting, VPS, and Dedicated Resources

   Shared hosting abstracts most server control, a VPS provides an isolated virtual server, and dedicated resources reserve underlying capacity for one customer. Learn the founder decision, practical evidence, and warning signs that matter.

7. Lesson 7

   Deploying Node.js Applications to a VPS

   A Node.js VPS deployment runs the application process on a virtual server behind managed networking, certificates, process supervision, and operating controls. Learn the founder decision, practical evidence, and warning signs that matter.

8. Lesson 8

   Deploying PHP Applications

   A PHP deployment places application code in a compatible web runtime with configuration, dependencies, writable storage, database access, and scheduled work. Learn the founder decision, practical evidence, and warning signs that matter.

9. Lesson 9

   Reverse Proxies and Process Managers

   A reverse proxy receives public traffic and forwards it to applications; a process manager starts, supervises, and restarts long-running application processes. Learn the founder decision, practical evidence, and warning signs that matter.

10. Lesson 10

    Environment Variables and Secrets

    Environment variables provide runtime configuration; secrets are sensitive values such as credentials and signing keys that require stricter handling. Learn the founder decision, practical evidence, and warning signs that matter.

11. Lesson 11

    Databases, File Storage, and Backups

    Application data, uploaded files, and backups have distinct storage, durability, access, and recovery requirements. Learn the founder decision, practical evidence, and warning signs that matter.

    Open Lesson

12. Lesson 12

    Monitoring and Observability

    Monitoring watches known service signals, while observability provides enough logs, metrics, and traces to investigate unexpected behaviour. Learn the founder decision, practical evidence, and warning signs that matter.

    Open Lesson

13. Lesson 13

    Rollbacks and Failed Deployments

    A rollback restores a previously working application state after a release fails, while data changes may require separate recovery planning. Learn the founder decision, practical evidence, and warning signs that matter.

14. Lesson 14

    Choosing Infrastructure for an MVP

    MVP infrastructure is the smallest operating arrangement that meets the product's runtime, data, availability, security, and recovery needs. Learn the founder decision, practical evidence, and warning signs that matter.

    Open Lesson

15. Lesson 15

    Estimating Infrastructure Cost

    Infrastructure cost includes base services, usage, storage, data transfer, backups, monitoring, support, and the labour required to operate them. Learn the founder decision, practical evidence, and warning signs that matter.
