REST API design focuses on creating clean, efficient, and scalable web services.

An API Gateway simplifies client access to backend services in microservices.

Monolithic and microservices architectures each have unique advantages and challenges for software development.

Search engines collect, index, retrieve, and rank documents to provide relevant results.

Microservices are useful when you need independent scaling, deployment, and clear boundaries in software design.

Microservices and modular monoliths differ mainly in deployment and communication methods.

Database per Service ensures each microservice owns its data, reducing dependencies.

FAANG interviewers evaluate problem understanding, architecture, scalability, and communication skills.

Load balancers distribute traffic across multiple servers to enhance performance and reliability.

Choosing the right boundaries for microservices is crucial for effective architecture.

Stateless servers are easier to scale because they don't store user session data locally.

FAANG engineers use high-level design principles to create scalable systems.

Microservices can communicate using five key patterns based on their needs.

gRPC supports four communication patterns: Unary, Server Streaming, Client Streaming, and Bidirectional Streaming.

API Gateway, Proxy, and Load Balancer serve different roles in managing requests and traffic in systems.

A reverse proxy routes client requests to different backend services efficiently.

The Bulkhead Pattern isolates resources to protect critical workloads from failures.

gRPC allows efficient communication between services using a structured request-response model.

Choosing between a shared database and a database per service affects system design significantly.

Graceful degradation allows apps to function partially during service failures.

A CDN speeds up web applications by caching content closer to users.

DNS resolution translates a URL into an IP address for web access.

REST, RPC, and gRPC are different methods for communication in software systems.

HLD provides an overview of system architecture, while LLD details implementation specifics.

Service Discovery helps microservices locate each other dynamically without fixed IP addresses.

The Transactional Outbox Pattern ensures database updates and event publishing are synchronized to avoid losing events.

Vertical scaling means upgrading one server, while horizontal scaling means adding more servers.

L4 and L7 load balancers differ in how they route network traffic based on layers of the OSI model.

Cache breakdowns can overwhelm databases, but request coalescing solves this issue.

HTTP methods tell the server what to do, and status codes tell us the result.

Functional requirements define what a system does, while non-functional requirements define how it performs.

The choice between SQL and NoSQL databases depends on your application's specific needs.

The Cache-Aside Pattern speeds up data retrieval by using a cache to store frequently accessed data.

Dependency failures can disrupt applications, but resilience patterns can help manage them.
