I would say this is as legendary as the iconic Microservices presentation by Netflix. 6 years has passed, but those were presented here are still as relevant as ever.

Excellent presentation that talks about different types of application architecture patterns leading to micro services and then different patterns and concerns for micro services architecture But everyone should make their own assessment on whether microservices is the right architecture for what they are trying to solve

From listening to this topic you begin to see how we can't really decide on our choice of architecture. We've done request-response, we've done events, and yet we keep changing vacillating back and forth between the two. Coupled but simple, Decoupled but complex. Kafka's main feature that is different is replaying event streams and it's scale. That is what is driving all of this re-evaluation of architecture design. However, microservices have produced a similar consternation over system design about how these services should interact with each other and how much each service should be responsible for its own destiny (ie a service unto itself, or a collaborative member of a larger system). And, now we're suggesting duplication of storage within the microservices. Each service will now store a copy of all of the data its dependent upon is the advice du jour. At best this is mere duplication of work at worst this has the potential to just recreate many monoliths especially for services that depend upon many things which always happens as product cycles demand. Certainly this can't be good advice for storing user information which has PII concerns and security implications. It doesn't make sense to spread data across many storage tiers that requires extract careful logic and governance unless you're just trying to make your CISO's job harder. Reusing APIs isn't just about data; it's also logic encapsulation! Which if you follow this advice of storing other microservice's means you now have to follow the logic that goes with that data too. Just having the data doesn't absolve you from the responsibilities of using and managing that data. The utopian dream of events everywhere and little to zero request response will be limited by these inconvenient facts. Then there is the issue of microservices need reuse to keep them small. If I can push off logic that isn't central to my problem domain then I can simply reuse someone else's work, and that keeps me light and small. Yes it creates a dependency, but I'm trading off my independence for convenience and a smaller footprint. There is lots to like about Kafka and event streams, and persistence of streams really is what's new here, but I'd be careful about how much this "changes everything" mentality you take away from this because we've seen this play before.

The consumer does not necessarily have to know the offset though (at 33m30s). Kafka stores the offset after commit.
@guidoschmutz
4 жыл бұрын
Yes, that's correct, but it's still not really "known" to the Kafka broker. It's just another topic which is used to store the offset. Conceptually I would still argue that the consumer "knows" the offset and is responsible for it, i.e. he is in control of how often the offset is commited (into the _offset topic)

This is a great talk, one question that I have is: People treat order Pizza as a typical async scenario and a good example for event driven architecture, like I put an order event, then get back the order finished event etc. Most cases, the client-side just want to get the realtime data, like I try to get my messages, get the latest emails, use credit card to purchase something. Does this mean we can't use event driven architecture here for the online process? Only for the offline BI/Search purpose?

Client side is sending and receiving events as well. Email client is sending emails but is also receiving emails from others to be displayed on its UI.

nice presentation, tnx a lot. this is close how we do write our microservices. If you use eventsourcing you can simply expose you events with CDC (debezium), so you dont have any mechanics in you software for event sending.

That's what we got, of course it was a couple of years ago. I'm talking about persistent messages, send within a transaction to a clustered JMS message broker. The "within transaction" is a bit an unfair comparison, I agree, as Kafka does not participate in transactions. But the sending of persistent messages is important. Sending JMS message in a "non durable" way will of course allow for a much higher throughput.

SOA and (Micro)services that is original. I guess (Micro)services are not real microservices. Yesterday's technologies with Kafka :)

No, the idea was to say that Micorservices could be seen as SOA done right. I'm not promoting "old SOA style services" communicating with Kafka. But it also does not have to be Microservices to get a benefit with decoupling through Kafka. That's why the title is (Micro)services. At the end you can profit as soon as you start creating smaller application modules and Kafka can help to decouple them.

hi Guido, Interessing slides and work!! But i'd like to seek attention on the part about microsevices database. you say "microservice might share a central database to exchange states at low level with other (Micro) seevices". I think that's against the microservices principles, patterns and best practices, namely independency and non-centralization. As of a statefull case (vs stateless) and self-boundary , a microservice must handle data (input) contained in its scope (domain/context/subcontext). Thefore, Payment can't share state at low level with Order. But paiment can only do so with a microservice part of its domain context/subcontext boundary. Any external-domain microservice must exchange through endpoint, topic, etc.Because a microservice is and must be responsible for its own inner logic. So when presenting SOA along side microsevices we need to be carefull, as soa is used to implement component-based services:) I really appreciate your job
