Step 1- create an amazing open source technology that is super complex and difficult to use
Step 2- create a paid service that makes it easier to use
My man started getting sponsors 🎉❤
Disagree with most of this video.
1. Consolidating the tech stack has huge advantages from better resource utilization to reducing dependency issues and vulnerabilities. Stick to as little as required.
2. For most purposes microservices and Kubernetes are overkill. I lost count of the number of times microservices apps end up being more complicated and more expensive to manage when moving from monolith. Not to mention performance hit. I hope you have heard of the Amazon Prime Video story. It agrees with my experience.
3. Microservices are specifically useful only for cases of large number of small atomic tasks happening very frequently.
If you cant explain it simply you dont understand it well enough. (Albert Einstein). This man really understand things very well
Was always afraid of Docker and Kubernetes. I am still afraid but at least now I understand what they do lol. Great channel
React and Next courses please, can`t wait any longer !!!
there are already tons of courses on youtube for free! Just do a simple search and you'll get them.
Love your content ❤
Great vid! Btw, looking good on that new look with glasses
Thanks for the video
This is great!!
Thank you! Thank you so much, Mr. Wesley! 🎙👏👏👏👏

Any update on the latest course or is it no longer coming? My boss keeps pushing me to buy the latest Javascript Mastery NextJS course but I told him that I'm trying to wait on Bytegrad's course, but he is bugging me everyday.
new course is still not up ?
is this the next course after react/nextjs course ?
is Acorn opensource and free to host on self VPS or any other tool ??
where is the course :
Microservice tutorial please 😂🤞
How do big companies do the same for their database at scale?
Do they have one database which all the services use to store data or do they have multiple databases?
One of the characteristics of micro-services is “Decentralised Data Management”, meaning that each micro-service should have it’s own database. You might ask what if one service needs data that is stored in another service’s database. Well, you can communicate between services using a message broker like Kafka ( there are other ways as well)
@@eltonsampaio7652 wow, interesting. Thank you for the reply ❤
Lets say we have these N micro services in N different repos. Where does the acorn file live and how do we do the whole orchestration and dependency dance for deployments.
At my current company, these is a ton of human effort that is required to coordinate between services owners so that services go out in a very controlled manner. Super clunky, slow, and expensive
What about if we have for example a Database as a service and inside of it we have for example 1 million data of products for example, and sometimes we have to calculate and get many products in same time how can we optimize that ? can we cut the database into multiple ? cause in this case even 1 people can be expensive on the request
On client side, you do pagination. Limit the number of items on page. You can also add a cache layer, if multiple requests are made almost at the same time, just return the cache. On the database side, you need to use indexes where appropriate, write performant queries, etc. What you said about breaking database into multiple is called sharding.
You know you can build monoliths in this same modular way?
I have doubt in my mind. Can we have different middlewares for different path? Can we also have multiple middlewares for the path?
yes we can
It would be helpful if you could make me understand @@otis2646
U should make real project for this
you got glasses lol! how much power (glasses)?
Hahah medium strong
