Single Server Applications
Single server applications are software systems deployed on a single physical or virtual server, where all components (e.g., frontend, backend, database) run on the same machine. This architecture is simple and cost-effective for small-scale or development environments, but lacks scalability and fault tolerance compared to distributed systems. It is often used for prototypes, internal tools, or low-traffic websites where high availability is not critical.
Developers should learn about single server applications when building simple projects, testing ideas, or working in resource-constrained environments, as it minimizes complexity and infrastructure costs. It is suitable for use cases like personal blogs, small business websites, or proof-of-concept demos where traffic is minimal and downtime is acceptable. Understanding this concept helps in transitioning to more scalable architectures as needs grow.
