Web Server Explorer
HTTP Request / Response Lifecycle
Learn how web servers handle incoming requests. Test GET, POST, PUT, and DELETE methods, inspect headers, and observe status codes in real-time.
Load Balancers
Distributing traffic evenly across backend fleets
Learn how load balancers route incoming requests to multiple servers to prevent bottlenecks, scale capacity, and implement horizontal failover.
Cache-Aside Pattern
Accelerating data retrieval with Redis and Postgres
Understand the industry-standard cache-aside caching mechanism using a high-speed Redis cache in front of a Postgres database.
API Gateways
Centralized entry points for microservices routing
Master path-based routing, service pool mappings, and client query resolution using a centralized API Gateway node.
Valet Key Pattern
Offloading file upload bandwidth to Cloud Storage
Learn how to use pre-signed URLs to enable clients to upload large binary assets directly to object storage without choking backend servers.
Message Queues
Decoupling workloads with asynchronous message queues
Learn how message queues enable reliable, asynchronous communication, buffer spike traffic, and implement the competing consumers scaling pattern.
Publish / Subscribe
Event-driven microservices fanout routing
Learn how Pub/Sub brokers distribute messages to multiple subscriber services in parallel, enabling decoupled event-driven architectures.
