Cloud computing is the on-demand availability of computing resources β€” such as servers, storage, databases, networking, and software delivered over the internet. Instead of maintaining physical infrastructure, companies can leverage cloud providers to scale resources dynamically.

Common Cloud Architectures

  • Microservices & Serverless β†’ Efficient, event-driven models
  • Monoliths β†’ Traditional, tightly coupled applications
  • Server vs Serverless β†’ Trade-offs between managing infrastructure vs. event-driven execution

Benefits of Cloud over Traditional Infrastructure

  • Cost-efficient β†’ paying only for what you use
  • High availability β†’ global distribution of resources
  • Security & Compliance β†’ provides manageable security tools and encryption
  • DevOps Friendly β†’ CI/CD pipelines, Infrastructure as Code (IaC)

Dangers of Cloud Computing

  • Vendor lock in - difficult to migrate from one cloud provider to another
  • Unpredictable Costs - pay-as-you-go pricing can lead to unexpected expenses if not managed correctly
