There are two approaches and many shades to design: top-down (uml, waterfall) and bottom-up (exploratory). I do bottom-up a few hours or days, then draw some uml, then go back to the code and repeat the cycle. The bottom-up first helps to get the ideas out, like you said "write to think". Yet still, doing some diagrams, writing down some architectural principles, helps keep a straight direction, without zigzaging in your decision making too much. It's a dance. Top-down helps with focus, but bottom-up (the details) are whispering in your ear what is right, and in a clean architecture the details always win. Do not overdo the diagrams, do "just enough" for you and the team. I'm a CTO in e-commerce.
@@fahmiirfan6923 been hearing this shit for like 3 years (from time you wrote your comment so 6 now) still waiting for this yet yeah sure it might happen but if I'm too old to work anyway who cares
If you can think of more of these types of videos with similar processes, please make more of these videos. They help tremendously because I had less than 2 years of industry experience before starting my own company.
Damn!! I'm currently reading "Teach Yourself to Think" by Edward de Bono. And I must say it really correlates to how you think. Great stuff btw, Kudos!!
Hussein is a principal engineer. He mainly talks about GIS system, database, network protocols, and some others. I actually feel he started to work for his RUclips channel full time now.
Hey Hussein. Can you share one of your designs including complete pack of docs from where you started and how the design evolved through out? Obviously if this does not conflicts with any of the policies :)
It's not only for objects -those are class diagrams. They are many many other types of diagrams and definitely they help architecting and many other activities.
Loved it Hussein! Though the uml diagrams etc..I believe that they provide a universal standard of representing a software design. Though a standard is not successful if less people understand it. :D
It makes a lot of sense. I would really love if you can make a video to architect a demo software using this technique. Thank for consistently uploading awesome contents.
This was a very useful video, Hussein. The only thing that would have made it better is some visual samples of drafts you created through each step of the process. Or, better yet, maybe you'll do a livestream of one of your work sessions. 🙃 One question, please: do you have any book/textbook recommendations for software engineering? I have very little programming experience and I would like to understand first principles, patterns, architectures, and best practices related to designing and building software. Thank you. Happy New Year to you and your loved ones. May 2021 be infinitely better than 2020. 😊
I've been trying to get better at this. I've really enjoyed using Invision Freehand as a tool to come up with my ideas. It's like an endless whiteboard that allows you to create blocks and arrows.
I think you have mentioned in the past that you are more of a visual learner. Can you share some of your favourite visual resources like YT channel that you personally use when it comes to tech and back-end development?
How do you start the process of understanding the fundamentals of some applications/ tech ? By reading books/ documentations or implementing it or by implementing the stuff or watching some videos.
Hussein, you've talked about all sorts of software parts of the system, but how do you actually choose from all of those? Let's call them tools. There are multitude of them out there with different pros and cons, some are matured some are not enough, some have extra features some don't. And new tools with buzz-word names just keep appearing every month, so you can't possible *know* them all, or try them all out enough to be an expert. So how to deal with this infinite variety problem? Do you design the system out of your personal past experience and prefer tools that you are already familiar with, which could be ok in some cases, but not ideal?
Thank you for sharing your knowledge Hussein. Great video!! If possible, please make a video explaining when we should use an API Gateway instead of a reverse proxy in order to expose k8s services through a single endpoint (e.g. ambassador instead of haproxy or nginx). API gateway vs reverse proxy? Also what is the best API Gateway in your opinion?
Excellent video that showcases your thinking process around software architecture! How one can develop the right mindset & learn the right skills of software architecture ?
Could you please design a simple system like a school manage system which will be microservice based. There are lots of system design in youtube like facebook, uber etc. But from those I can't get a clear concept as those designs are actually very big and doesn't change along with changing requirements and throughput demands.
Thank you for the informative video! for the diagrams, do you use c4-model? if not what do you think about it ? for actual documentation of the architecture, do you use a specific framework like togaf ? and could you please do a video illustrating what you mentioned in this video starting from a real world problem. Thank you
Thank you so much, Hussein. If I want to be a better engineer in general what are your suggestions for me (Courses or Books)? I want to be a better software engineer, be able to design systems, and a good understanding of design and architecture. OOP. I have 7 years of coding mainly in JAVA, I like to move my career and understanding to the next level. Cheers,
i want to know more about how can we systematically present the system design to the business partners. and what terms should i follow when it comes to business.
Please make a video about an interview where they ask questions about a pseudo code first and then ask about it's architecture and design and also about extending the design
What about the agile thing? If I write EVERYTHING down, ask stakeholders about EVERY possible case, ask them EVERYTHING that they might need in future, thinking about all the complexity and changes that may arise in 2-3 years later, etc., I suppose this will take forever to design that software. What do you think? Isn't it the old waterfall approach? Btw, I'm not debating on these approaches, I have issues myself understanding the boundaries between Agile an waterfall. Precisely, Where's the design and architecture step in Agile do you think? I'm searching for answers to these questions for a while and literally I couldn't find anything. So any help is appreciated 🙂
Good point, the process I describe can be applied to both agile or waterfall I talk about agile vs waterfall here ruclips.net/video/XGOxLyWFfl0/видео.html
You mentioned strangely detailed description of what stakeholders want (like for a chat app whether we want to see that the message is read) AND then making architectural decisions based on that. These kinds of requirements will naturally pop up in dozens AFTER you build a prototype and then regularly during product development. Maybe you meant this, but I didn't catch it and for me it seems important that your architecture is flexible enough to support such kind of unforeseen requirements later. And if each such requirement will have to go through the same rigorous process with writing and all, you will be too slow in my experience. In many cases it is better to move fast to try many ideas and then refactor when you see that the ideas are good.
It might not have been cleared in my video but The approach can be applied to both agile and waterfall, that is why I mentioned the min-ship or (MVP) which will need to be written and finalized first this will have the least amount of needs to get done for maximum impact. The rest of holistic details are for the overall project and might take way more time to finalize and it will be a continuous improvement process. Once MVP is deployed the feedback will loop back and improve the design documents.
For MVP about 3-4 weeks, for the whole process takes many months and will be continuously evolved once the MVP is deployed. I miss the waterfall days where we used to spend 2 months to do the spec once and go to work..
Would you be open to making a video going through an example? Perhaps for a relatively simple software system. Also are there any resources online of anybody going through an example? Thanks
Man this is the channel needs some real attention ... the youtube is filled with stupid "How to make a todo list" or making a "Instagram Clone" ... this is some real information which you even need time to digest.
Really great, we need a voice-chat on discord Hussein to talk more about thing related thanks for udemy course by the way I love it ,keeping on doing your great job #Good by 2020
"Everyone on the engineering community knows that all these diagrams are bs" Seriously no joking here, these days people ask me to draw diagrams just for the sake of procedure and calculating the price. Most people just copy their pre made UML with little modification, more often than not you can't count on them when it truly matter, most likely not up to date, especially after people introduced AGILE and other bs to our engineer life, think that we can make better quality product in shorter amount of time. Nah, we can only make workable product with that amount of time, don't expect it to be well documented.
"Don't think to write, write to think." 👌👌

This is why I’m not afraid that robots will take my software development job anytime soon.
It is extremely creative job, AI can automate certain repetitive tasks but can’t do the innovative part.

I cannot believe why i found this channel this late, it feels like sitting on gold
By that i mean it actually hurts😂
Same haha and it's been 3 weeks
Still much gold hahaha
I know right, so much content

Literally! no one has ever told to subscribe so beautifully
Hey Hussein. Can you share one of your designs including complete pack of docs from where you started and how the design evolved through out? Obviously if this does not conflicts with any of the policies :)
Sounds more like “Event Storming”
Thanks for sharing.
Thanks
I would love to see doing a full series on this and definitely design pattern series
Sir, u are great, the way u explain is very clear and concise
Great work Hussein! Big fan of your videos... Would really love to hear your thoughts on network storage / cluster storage technologies!
Hola Hussein, 1st with love. :)
🥇
Great Video.
Can you please create one more video to explain the same thing by taking a specific use case like e-commerce/e-learning/social media app?
I would equally love to see such
Mee too
You’re right on time. I’ve been googling programmer notebooks and how to design software the last few days.
This is such an amazing video, thank you always Hussein
You are the coolest speaker I've ever seen. Keep going!!!
Thanks! 😃
Would really love to see your version of a design document. Either mocked or redacted.
You are a great computer science teacher. I now enjoy learning the concepts, which I despised in my University 😊
I was studying uml this year and it was made for modeling objects, even the author says to not use it for architecture
Uh?🙄
It's not only for objects -those are class diagrams. They are many many other types of diagrams and definitely they help architecting and many other activities.
Loved it Hussein! Though the uml diagrams etc..I believe that they provide a universal standard of representing a software design. Though a standard is not successful if less people understand it. :D

Hi. It was really helpful.
How long does the entire design process take? And a rough time frame for each step?
