Great explanation and content. Your video deserves more views. I’ve used circuit breaker, retry, timeout, fallback patterns. They are great, I have also built monitoring around retries, timeout. If the number of retry increases, it notifies with alerts that could provide an indication of a network latency problem causing requests to timeout and retry. Implementing these patterns with monitoring greatly improves the resiliency of microservices.
I am unable to understand how if payment service will fail so all other microservices goes Down? i think main motive of microservice is all worin/not-working in it's own env. If order service call payment and payment service is down so that particular order will not place but it's not cascade to rating or browsering or any other service? may be I am missing something
You're absolutely right that one of the main benefits of microservices is isolation-each service operates independently. If the payment service fails, it should not directly cause other unrelated services like browsing or ratings to go down. However, the issue could arise if services are tightly coupled or rely on synchronous communication. For example, if the order service depends on payment and is designed to wait for a response before proceeding, it might get stuck or fail when payment is down. This can sometimes create a cascading failure if services aren't handling failures gracefully. The key to preventing this is fault tolerance. Implement patterns like circuit breakers or timeouts, so if payment is down, other services can still function normally, and the failed calls won’t cascade to affect everything else. It's about ensuring each service can handle failures in others without affecting the whole system. Please checkout microservices playlist where I cover each of the patterns with examples.
@@ByteMonk Yes, exception handling and logging while calling to other services is very important so that we can prevent below- 1. Proper exception message to users so that they can wait until service will recover and notify service will notify. 2. We should use global exception handling for user understandable message. 3 at the time of failure we should do proper logging message so that developer can understand what's happened at that time and they can implement/analysis either circuit breakers or retry policy(time gap). I want to ask one more scenario I think we should not implement fault tolerant if that particular service synchronious call for data is required before save or create record because we can't store incomplete data. So in this case service should let's developer/user know that particular service is down or slow and take necessary action otherwise all request will fail.

awesome sir pls keep making the videos with your style really very helpful..thanks a lot and all the very best.
Thank you for the support, I'll keep making videos on these topics!
Great video Buddy. Looking for more content from you
we are using a fallback circuit breaker and timeout and retry. I didn to hear bulk head. now I am able to understand.
full video on bulkhead coming up next :)
Awesome bro keep it up.
Good Video. Simple and straightforward explanation. How you edit your videos? like your animated diagram with text effect.
