A recent production issue reminded us: never trust remote systems to behave.
We integrated Netflix Hystrix to wrap remote calls with: - Circuit breaker - Timeout - Fallback
Sample snippet:
@HystrixCommand(fallbackMethod = "defaultResponse")
public String getProfile(String id) {
    return profileService.call(id);
}

public String defaultResponse(String id) {
    return "unavailable";
}
One timeout shouldn’t bring down your system. Hystrix made sure of that.
