Networks & Communication
API styles, protocols, network components, service meshes, and how it all fits together in cloud VPCs.
API Architecture Patterns
9 min →REST, RPC, GraphQL — when to use each. Versioning, authentication, gateway patterns, and the cross-cutting concerns of designing APIs for SaaS at scale.
Protocols and the OSI Model
8 min →The OSI model, the practical TCP/IP model, the TCP vs UDP trade-off, and the HTTP versions you'll encounter in production.
Key Network Components
10 min →Load balancers, API gateways, proxies, CDNs — the building blocks that turn a single application into a distributed, resilient platform.
Service Meshes
8 min →The service mesh pattern moves cross-cutting service-to-service concerns out of application code and into infrastructure. Sidecars, control planes, and the trade-offs.
Network in AWS
11 min →How AWS networking actually works — accounts, regions, AZs, VPCs, subnets, security groups, and the connectivity options for hybrid and multi-account setups.
