1. System design 2 all basics

2. In System Design Life Cycles, without the  designingphaed phase , one cannot jump to the implementation or the testing all part. System Design is a vital step and also provides the backbone to handle exceptional scenarios because it can represents the  business logic  of the software.

3. ystem architecture overview : Defines the major components, modules, and how they interact (e.g., services, queues, databases) . Data flow and component interaction : Illustrates how data moves between modules, along with key integrations and interfaces. Technology stack and infrastructure : High-level decisions on frameworks, platforms, hardware, databases, and hosting setups.

4. tives developers a clear, actionable blueprint to build each component. Once a High Level Design is built by stakeholders, it is the job of senior developers and designers to create a low level design.

5. Concept Example Question Why it’s asked Load Balancing How do you scale your web servers? Scalability Caching Which data should you cache? Performance Database Sharding How to scale databases? High data volume Replication How to ensure availability? Fault tolerance CDN How to serve images/videos fast? Latency Message Queue Why use Kafka? Async processing Consistency Models Strong vs Eventual Trade-offs understanding

6. earn the Basics First Caching, Load Balancing, CAP Theorem, Sharding 2️⃣ Solve Design Problems Daily Pick 1 system → break it into: Requirements APIs Database schema Scaling methods
