In this lightboarding explainer video, Dan Bettinger gives a broad overview of microservices.
By comparing microservices application architecture with the traditional type of monolithic architecture through the example of a sample ticketing application, Dan lays out the myriad advantages of microservices, as well as solutions they provide to the challenges monoliths present.

Great example of how to deliver a complex topic in an easily understandable manner - thanks
"Every app function is it's own service"
That's the line I needed to see. Now I get it.
Thank you.
Thank for explaining in such an easy manner.
AMAZING explanation, captures really important details in a simple way. Thank you.
Thank you for watching, we're glad you found it useful! 👍
Brilliant video. Thanks Dan!
This must be the only video explaining the whole concept in comparison so clear. Really brilliant as always from IBM Cloud. You should create an academy.
But, you might not need microservices. Do not get dazzled by the buzz around microservices and spend months trying to convert your monolith to microservice architecture.
Dell's example on how they screwed 18 months of work with 120 developers just to convert their application monolith to microservices must be a good example on much & many things can & will go wrong.
The only thing I would suggest double-checking before making the decision of microservices is language independence. In real-world applications that's not something to be taken for granted.
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.
Totally agree. And they'll be making videos just like this one to sell us on it.
It depends honestly. if you are a 10 person team with a straightforward application, the microservice overhead might not be even worth it.
@@sinajafarzadeh9577 can u please guide me more about integration process management (ipm). i am a fresher in an IT company and got this as my domain
And repeat this over and over in the next decades lol
Uff! Couldn't agree more
4:30 "A distributed monolith", awesome!
I like the way he summarized this very intensive task at 2:58
Thanks for making these concepts so easy to understand.
Very straight forward and easy to follow. Great video.

crystal clear. thanks!
Thank you, Geat explanation
Excellent video!
Perfect explanation sir
OMG best explaination ever!
Thank you!
Simple and clear.
Thank you! 💪
well articulated
Excellent Explanation!
We're glad to hear this, Ann! Thank you for watching, Dan.
simple and quick
Beautiful video
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?
great video, thanks 😊
Finally, I understand. Thank you. Btw, are you really writing backwards or you just sort of flipped the video?
I was wondering the same. They flip the video, so most of the guys become left-handers :)
Explained here: th-cam.com/users/postUgzf5SL_yh9NglCJzgF4AaABCQ
great big picture explanation
excellet explanation
nicely explained
thanks!
Best video on microservices
Thank you! 🙏
Thank you , I'm gonna use this video in an English class.
Hi Teacher Chil...please let us know how that goes! Thank you for watching.
@@IBMTechnology I asked my group of IT professionals to watch the video for listening practice and vocabulary acquisition. They're all involved with apis and microservices at work.
Then in class I highlighted some of the phrases you use in the video.
off the bat
under duress
up and running
talk over APIs
thereby
at best
And we all created examples and conversations based on those phrases
The idea behind this is to expose them to good sources of spoken English with themes familiar to them.
So thank you very much, they all liked the class and your video.
And the way you use that glass to write on makes the watching experience really interesting.
Thanks a lot
Beautiful
Thanks a lot for this! Though I would like to ask, what is a DevOps pipeline? Any examples, please. Is it like a testing software? Please elaborate. Thank you.
Push code to branch in GH -> build that code (jenkins job start) -> test it -> deploy it (optionally, end of jenkins job)
there is one Pipeline example.
Thanks 😊
thank u so much sir
WoW!
Hero deployments... LOL, cool presentation, Very clear explanation thank you.
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.
Through network using protocols such as HTTP or even lower-level such as TCP or UDP. Sometimes you go higher level and use GRPC wich uses HTTP2+ under the hood.
And you can use XML/JSON which is of course on HTTP.
So basically modular web apps inside Docker containers?
25 years ago there was Microsoft DCOM , Distributed Component Object Model (DCOM) Remote Protocol, a vision that failed
So, that is very similar to the way of using nodes in ROS
Cool! IBM
Kind of odd that when I tried to watch this video as embedded in IBM's own microservices article I get the error, "Unauthorized domain: We're sorry, this content is only available on certain domains."
I knew I hated Java applications for good reason. haha thanks for the great video.
Great topic, but you didn't mention the Challenge for the Micro Services
I miss the Challenge section for Microservices 🤪
What is meant by hero deployment?
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?
is the concept of infrastructure as a code a huge benefit for microservices architecture?
Hey, there! In short... yes! 🙂 Infrastructure as code (IAC) allows for consistent automated deployment of infrastructure which decreases manual errors and increases efficiency.
We have quite a few resources, too, if you'd like to explore more on this subject:

@@IBMTechnology thank you , I will have a look :)
Aws loadbalacer took me to MICROSERVICES and i am now here
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...
CI/CD vs microservices?
I really hope you're not writing on my screen with a sharpie
There is no ideal solution especially when low talent is the norm.
Of course IBM will emphasis microservices. More server thay can sell lol
For 90% of companies, microservices are really a bad idea. Consultancy companies love to hype them because it drives demand for their services.
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.
Microservice is more a disaster than a benefit, all just big talk echo chamber. Netflix did it now everyone wants to wear the fashion.
Everyone telling what are microservices but no one tells how to create microservices. 😢
It’s funny how lefties are so messy, I should know I’m a lefty 😝
But it hain't cheap :'(
I have no background in any of this so everything being said sounds like alien speak to me...
