The RED Method helps monitor microservices using Rate, Errors, and Duration metrics.

Alerting helps notify the right people about production issues quickly.

The USE Method helps find and analyze infrastructure bottlenecks in software systems.

Database bottlenecks slow down performance, but identifying them helps optimize and scale effectively.

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

SLIs measure service performance, SLOs set reliability targets, and SLAs are customer agreements.

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

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

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

Timeouts in distributed systems indicate suspicion, not confirmed failure.

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

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

Scaling databases involves deciding whether to enhance read or write capabilities based on traffic patterns.

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

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

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

Token Bucket allows burst traffic, while Leaky Bucket smooths out traffic flow.

Distributed backpressure helps manage the flow of work between services to prevent overload.

Older offsets can overwrite newer ones in Kafka if not handled properly.

Choosing the right distributed lock depends on your system's needs and existing tools.

Fail Fast means stopping quickly on errors, while Fail Safe ensures safety in failures.
