• Cloud applications and services can be deployed using traditional servers or serverless architecture, each with trade-offs dependent on the scale, cost and complexity of that application or service.

Server (Traditional Infrastructure)

  • applications run on virtual machines (e.g., AWS EC2, Azure VM)
  • full control over server configuration, networking and scaling
  • requires manual provisioning, maintenance, and scaling
  • Best for: Long running applications, databases, and workloads that require persistent compute power

Serverless (Event-Driven Execution)

  • code runs on demand without managing infrastructure (AWS Lambda, Azure Functions)
  • auto-scales based on workload, reducing idle costs
  • limited execution time and cold stats may impact performance
  • Best for: short lived. functions, microservices, APIs , and event driven workflow
