Design Microservices Architecture with Patterns and Principles - Types of Caching

The video tutorial discusses different types of caching: in-memory, disk, and distributed cache. In-memory cache is the fastest but loses data on restart. Disk cache is slower but retains data. Distributed cache enhances performance and scalability by storing data across multiple machines, beneficial for distributed systems like microservices. The focus is on understanding these caching types and their use cases.

What are the three main types of caching mentioned in the video?

• Static, dynamic, and hybrid cache

• Primary, secondary, and tertiary cache

• Local, global, and cloud cache

• In-memory, disk, and distributed cache

Which type of cache is known for being the fastest?

• Cloud cache

• Distributed cache

• In-memory cache

• Disk cache

What is a key disadvantage of in-memory cache?

• It is very slow

• Data is lost on restart or shutdown

• It cannot be used in distributed systems

• It requires a lot of disk space

Where does disk cache store its data?

• In the cloud

• In the main memory

• On a network server

• On a hard drive or SSD

What is a primary benefit of distributed cache?

• It improves performance and scalability

• It requires no maintenance

• It is the fastest type of cache

• It is the cheapest option
