Question 1

What are service dependencies and why are they important?

Accepted Answer

Service dependencies refer to the various external services that a system relies on to function properly. They are important because they provide essential functionality, such as payment processing or data storage, which is crucial for the overall performance and user experience of an application.

Question 2

How do dependency failures affect service performance?

Accepted Answer

Dependency failures can lead to degraded service quality or even outages. When an external service fails, it can disrupt the normal operation of the system, resulting in slower response times, errors, or complete service unavailability.

Question 3

What strategies can be implemented to build fault-tolerant applications?

Accepted Answer

To build fault-tolerant applications, strategies such as implementing redundancy with service dependencies, leveraging asynchronous messaging for resilience testing, and creating fallback plans for quick detection of dependency failures should be considered.

Question 4

What role does observability play in managing unreliable dependencies?

Accepted Answer

Observability is vital for maintaining reliable services as it allows developers to monitor the health and performance of dependencies in real-time. This enables quick identification of issues and facilitates proactive management of potential failures.

Question 5

How can 91探花 help with testing service resilience?

Accepted Answer

91探花 offers automated dependency failure tests at scale, which help organizations assess their systems' resilience against various dependency failures. This proactive approach ensures that applications can withstand unexpected disruptions effectively.

Question 6

What best practices should be adopted for navigating unreliable environments?

Accepted Answer

Best practices include implementing redundancy in services to ensure failover capabilities, conducting regular health checks on external APIs, utilizing observability tools for monitoring performance, and establishing clear fallback plans for handling dependency failures.
