On .NET Live: Modular Monoliths with ASP.NET Core

When it comes to building robust ASP.NET Core apps, we often encounter the dilemma of choosing between monolithic and microservices architectures. While microservices offer scalability and flexibility, they also introduce complexity. Sometimes, a well-designed monolith app can be a pragmatic choice.

Steve's course:
Modular Monoliths From Zero to Hero

Guy turns up late to meeting and makes a bunch of open mic noise - absolute classic meeting. Thanks Steve, this is a great resource.

[JeanQPublique]

the best part was the desktop mic catching all the pen clicking and ambient noise.

But on a more serious note, Steve's stuff is consistently great. Very grounded and practical stuff. Keep it up!

[pedroluisrodriguezamador]

Congratulations, well done! I'm working on a new version for modular monoliths, taking this approach into account.

[nellya]

Thank you Steve. That was an amazing session!

Steve is an excellent teacher. I feel like Microsoft just gave me a free DomeTrain course. Thanks.

This architecture does tend to work great for business applications in my experience. We’ve done so many half baked microservices attempts that end up with all of the negatives and few of the positives. This is the type of thing is a sweet spot for a lot of the types of things I have to build.

I think the hosts need to learn some video call etiquette and ensure they're muted when they don't need to talk. And also wait for the speaker to offer up opportunities to take questions, rather than asking and breaking up the flow of the presentation.

Great talk from Steve though, very informative.

[chidii]

This is actually a good and clear session. Thanks

[SajadJalilian]

Thank you. This video is very insightful

[saqwerUA]

thanks! I catch a couple new things in .net stack I haven't thing before.

57:50 with the BackgroundJob for sending mails: how does this behave if you scale your modular monolith out?

[marklynch]

I have an email sending module and I need to have email templates for different entities that are in other modules. For instance, book back in stock email template, contact author email template, confirm email template (identity) etc. which staff can define via a cms. Where would these templates go, create a record for each template in the email sending contacts project?

Mediator, mediator, it feels like it has become mainstream to use it everywhere. What other approaches exist for interaction between modules/layers?

Good presentation, but I have to say the bombardment with popups on the bottom left is really distracting. It's not particularly relevant to the topic to know where the viewers are from. Background noise isn't good either.

[richardhaughton]

How would you integrate a blazor frontend in this modular monolith architecture? Would you add an Web API layer (BFF) to orchestrate different modules into a viewmodel?

[efezlfn]

I prefer
if(success)
{
return true;
}

But for this example return success; would be ok )))

I dispute that a Modular Monolith is easier to deploy than Microservices. The whole point of Microservices is that they're independently deployable. If your Users service, say, requires a change then you only need to deploy that one service - nothing else is affected. If you make a similar update to a Users module in a modular monolith, then you need to deploy the entire monolith. That's really a huge drawback, if you ask me.

Related, what about separating the commits from each of the different modules - you absolutely will have to do that if you have different teams working on each module, all with different priorities, deadlines, sprint/iteration schedules, etc. This also makes the side of things incredibly complex. So much so that I don't see how there is any benefit to a Modular Monolith at all.

[edfloreshz]

Is this project in a repository somewhere? I could really use it :) thanks

[mirkogeffken]

Never, ever have I built anything in the real world that wouldn’t work in this model. I know that someone who runs Emacs OS will disagree. Go at me bro!
