Definition:Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) provides raw virtualized computing resources (servers, storage, firewalls) over the cloud.
Detailed Technical Explanation
Business Perspective
IaaS offers maximum flexibility and cost control for custom enterprise cloud architectures.
Technical Perspective
Requires managing OS security patches, firewall security groups, and web server configurations.
Real-World Example
Spinning up Ubuntu virtual servers on DigitalOcean to host custom Node.js and PostgreSQL microservices.
Common Architectural Mistakes
- ✗Unpatched OS Servers: Failing to automate operating system security updates on long-running virtual machines.
