What are Microservices?

Amazing explanation!

clear explanation of complex concept in understandable manner

There is no ideal solution especially when low talent is the norm.

so good

same tiring incorrect explanation

This presentation is sadly very superficial. For any IT system, there are many different ways to allocate functionality to deployable units - ie there is a sliding scale from one company-wide monolith to a handful of larger systems to many smaller systems to truly function-level components. Each different level of granularity has its own advantages and disadvantages, and the optimal solution is likely to differ by business area - ie the optimal solution for a large system can well be a mix of components of different granularity. Very few large companies have a single monolith, and I doubt many companies use 100% fine-grained services either. Fine-grained components have some important advantages, but also some very nasty disadvantages. Moderate-grained components can potentially support elastic scaling without needing to be "single functions". What is presented here are truly two extremes, and while the disadvantages of huge monoliths are presented, the (many) problems with truly fine-grained systems are not discussed at all.

great big picture explanation

great video, thanks 😊

What is meant by hero deployment?

Very clear and helpful explanation. Just the right pace and amount of information.

If you are a start up or even developing something in a company that hasn’t been validated should you really go ahead and build a micro service based architecture considering it’s more timely and expensive?

I’d rather build something quick and dirty and get it out to my customers and get feedback than spend time building a complex architecture that might not be relevant because our customers don’t want what we’re building.

Does anybody have an opinion on this?

But it hain't cheap :'(

Beautiful video

Nice job, Dan. Good seeing you again!

I have no background in any of this so everything being said sounds like alien speak to me...

Awesome explanation - Thank you

Amazing explanation best one I’ve seen so far

OMG best explaination ever!

I miss the Challenge section for Microservices 🤪

Of course IBM will emphasis microservices. More server thay can sell lol

so bright and clear explanation !

Simple, interesting and example-based explanation. Thanks!

This is an amazing explaination. Thank you for making this video.

The video is bad. It literally says: a monolith has only disadvantages and microservices have only advantages. Too bias

AMAZING explanation. really thank you .

Thanks for making these concepts so easy to understand.

Great topic, but you didn't mention the Challenge for the Micro Services

So, that is very similar to the way of using nodes in ROS

Amazing explanation, thank you so much for this video.

Very straight forward and easy to follow. Great video.

Everyone telling what are microservices but no one tells how to create microservices. 😢

CI/CD vs microservices?

Aws loadbalacer took me to MICROSERVICES and i am now here

what about fetching data from different services. would it be painful if those has separate databases. how it would effect the time to fetch and coordinate those informations?

THANK YOU! very clear and concise and well explained! make more of these videos plz!

thank u so much sir

Thanks 😊

Very helpful video! Also this reminded me how much I love lightboards

Very awesome video with perfect notes. thanks...

For 90% of companies, microservices are really a bad idea. Consultancy companies love to hype them because it drives demand for their services.

So if all the microservices could be written in their own language. How do the communicate? Do they usually send strings, json or some other protocol? Because remote method invocation would be difficult if they use different languages.

What a fanstastic, smart presentation!

Perfect explanation sir

Beautiful

Cool! IBM <3

crystal clear. thanks!

I think the real world no real decoupling things. New business requirement come always caused changing from top to down, so here, it could be change required in thousand islands...

I’m willing to bet in a few years the industry will refer to “micro services” as a Thousand Islands and “monoliths” will turn into Panacea. Then tell us how coding in one style in a common code base with a single installation is so much better, reducing the maintenance nightmare, inter-system integration problems, and sub-fiefdoms that arose from the Thousand Island approach.

Thank you!
