Standalone vs distributed mode in Kafka - Quick Revision & Key Differences

Recall & Review

beginner

What is standalone mode in Kafka?

Standalone mode runs Kafka on a single machine where all components (broker, zookeeper) run together. It is simple and used for development or testing.

beginner

What is distributed mode in Kafka?

Distributed mode runs Kafka across multiple machines. Brokers and Zookeeper run separately to provide fault tolerance and scalability.

Why use distributed mode instead of standalone mode?

Distributed mode allows Kafka to handle more data, stay available if some machines fail, and scale by adding more servers.

beginner

Name one limitation of standalone mode.

Standalone mode cannot handle large workloads or provide fault tolerance because it runs on a single machine.

intermediate

How does Kafka ensure reliability in distributed mode?

Kafka replicates data across multiple brokers and uses Zookeeper to manage cluster state, so if one broker fails, others keep working.

What does Kafka run in standalone mode?

A Only brokers on multiple machines

B Multiple brokers on different machines

C Only Zookeeper on one machine

D All components on one machine

Standalone mode runs all Kafka components on a single machine.

Which mode provides fault tolerance in Kafka?

A Neither mode

B Standalone mode

C Distributed mode

D Both modes

Distributed mode replicates data and runs on multiple machines to provide fault tolerance.

Why is standalone mode mainly used?

A For production with high traffic

B For development and testing

C For distributed computing

D For cloud deployment

Standalone mode is simple and used mainly for development or testing.

What role does Zookeeper play in distributed mode?

A Manages cluster state and coordination

B Stores all Kafka messages

C Runs the Kafka producer

D Manages client connections

Zookeeper manages cluster state and helps coordinate brokers in distributed mode.

Which is a key benefit of distributed mode?

A Scalability and fault tolerance

B No need for replication

C Runs on a single machine

D Simpler setup

Distributed mode allows Kafka to scale and stay available even if some machines fail.

Explain the difference between standalone and distributed mode in Kafka.

Think about how many machines run Kafka components and what benefits that brings.

Why is distributed mode preferred for production Kafka deployments?

Consider what happens if one machine fails in production.
