# System Design - [🔀 Horizontal vs. Vertical Scaling](https://www.mohitkapadiya.com/system-design/horizontal-vs.-vertical-scaling.md): In the world of system design, scaling is a crucial concept that determines how well an application can handle growth and increased load. There are two primary approaches to scaling. - [📚Distributed Systems](https://www.mohitkapadiya.com/system-design/distributed-systems.md): Distributed systems are a crucial component of modern system design, enabling scalability, fault tolerance, and high availability. - [💾 Microservices](https://www.mohitkapadiya.com/system-design/microservices.md): Microservices architecture is a design approach in which a single application is composed of many loosely coupled and independently deployable smaller components or services. - [🔒Hashing, Signatures, and Encryption in Microservices](https://www.mohitkapadiya.com/system-design/hashing-signatures-and-encryption-in-microservices.md): All about how hashing, digital signatures, and encryption are integrated into microservices architecture with real-world examples, calculations, and visualizations. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
