Kubernetes Container Orchestration Cloud Native Patterns 2

Question 1

Which cloud native pattern involves running a secondary container alongside the main container to provide supporting functionality like logging or monitoring?

Accepted Answer

Sidecar

Answer

The Sidecar pattern attaches a helper container to the main application container within the same Pod, sharing its network and storage.

Question 2

In the Ambassador pattern, what is the primary role of the ambassador container?

Accepted Answer

Proxying network traffic on behalf of the main container

Answer

The Ambassador container acts as a proxy, handling outbound connections from the main container to external services.

Question 3

Which pattern is used when multiple heterogeneous services need to present a unified interface to a consumer?

Accepted Answer

Adapter

Answer

The Adapter pattern normalizes the output of different containers into a standard interface that consumers can uniformly interact with.

Question 4

The Strangler Fig pattern in cloud native migration is best described as:

Accepted Answer

Incrementally replacing legacy functionality with new services while keeping the old system running

Answer

The Strangler Fig pattern gradually migrates a legacy system by routing new functionality to new services while the old system continues to operate.

Question 5

In a cloud native architecture, what does the 'bulkhead' pattern primarily protect against?

Accepted Answer

Cascading failures by isolating resource pools between services

Answer

The Bulkhead pattern isolates elements into pools so that if one fails, the others continue to function, preventing cascading failures.
