In a microservices architecture, the pattern that isolates failures and ensures that a failure in one service doesn't impact others is called the ________ pattern.
- Adapter
- Circuit Breaker
- Observer
- Singleton
The Circuit Breaker pattern is used to isolate failures in a microservices architecture. It prevents a single service failure from cascading through the system.
Continuous monitoring in cloud environments is essential for:
- Detecting and mitigating threats
- Ensuring high availability of services
- Monitoring competitors' cloud usage
- Reducing cloud infrastructure costs
Continuous monitoring in the cloud is crucial for detecting and mitigating security threats, ensuring data protection, and maintaining compliance with regulations. It's not primarily about cost reduction or monitoring competitors.

In a scenario where there's a tight deadline to exit a data center, which migration approach might be prioritized, even if it doesn't yield immediate cloud optimization benefits?
- Rearchitect (rebuild)
- Refactor (re-architect)
- Rehost (lift and shift)
- Repurchase (buy a new one)
When facing a tight deadline to exit a data center, 'Rehost' (lift and shift) might be prioritized, even if it doesn't yield immediate cloud optimization benefits, as it's the quickest and least disruptive approach.
A key advantage of SaaS is the elimination of the need for individual ________ and maintenance.
- Data Centers
- Installation
