[@wouter1625]

My only advise would be: Don’t try to make these difficult decisions all at once, go with whatever you think is the easiest and replace stuff when necessary.

[@elan2199]

I can't count how many projects I started exactly like this. I spent hours trying to learn which language, framework, database, architecture, hosting service etc. Just to end up giving up before even finishing an mvp.

[@IncomingLegend]

@@elan2199 you may think there could've been a better way but trust me, all options will give you headache at some point, some of the more so than others, that's true...

[@hojdog]

Yeah, I thought the same thing. It sounds over-engineered for a new project (Unless you are a youtuber wanting to make content) But if you want to seriously build something, just build.

[@caiocutrim3596]

I thought the same thing, yeah. It is like, put to much effort to bring up technologies that may be aren't aligned with the company, for example: Who will even maintain a rust application if it is not used widely in the company? I thought if it is started simpler things could be replaced if needed. Find specialized developers is hard if you thing about business.

[@lechuck2011]

My personal advice: go with the thing you know the most and let you to develop faster to get an MVP as soon(and cheap) as possible. Then if the idea works, you can improve it as the business grows. In my personal opinion, if the project is intended to become a business it is the best to think in how you could test your idea and then the engineering stuff we all loved. I am working on a personal digital business too and I started to think in the same stuff(language, platform, etc) then I realized I wanna to have a customer testable version as soon as possible and I went to node/express and heroku and a well-organized monolith (think I can develop faster) instead of my initial idea of microservices, aws and golang

[@siddu6003]

[@maskedvillainai]

Ha I literally just wrote that actually that’s hilarious

[@appleman2590]

That's right. Though on my day work we have our super big 11 years old monolith project with a lot of legacy, we still are able to move some parts of it to microservices all the time, update codebase etc. For the start - the main purpose is make testable product for you potential clients. Your project won't likely be that enormous and difficult through first couple of years, so that you would not be able to change anything in architecture. As you hire bigger and more experienced team in the scope you are willing to implement the architecture in, you will be able to scale and navigate product development in any direction you want

[@semanser]

I was also considering between Go and Rust for my current startup and I decided to use Go. I absolutely agree about all the reasons that you mentioned and my experience has been great with Go so far. It's extremely easy to start with and it gives you ability to write production ready code on week two. Rust is great when you need some of it's low level functionality but I feel it's an overhead in 90% of all cases, especially if we're talking about backend development. That being said, Go has a great ecosystem and an amazing standard library that allows you to focus on your product instead of fighting with the compiler itself. I know, the Rust borrow checked is supposed to help in a long run but the question is if you're ready to sacrifice 50% of your development performance for 10% of execution speed/memory.

[@withmarko]

Hey thanks for sharing your experience. Yeah, I'm leaning towards go myself. Am excited to dive deeper in one of the next episodes! Is your startup live, btw? 😃

[@younlok1081]

@@withmarko i think go is good but things become messy once the project is bigger i built a project with it before and then things become pain so i actually switched to node / express and it was an easier time for me tbh

[@sternenlp8258]

We are using go in our Startup as well and so far we are pretty happy. With the right structure the code is maintainable and easy to understand. We are also using the microservice architecture, because we have a large user base. And that is working for us pretty well.

[@LabhamJain]

[@mario_luis_dev]

having the rain noise in the background while walking through the backend language options was a great touch Marko, loved it!

[@mario_luis_dev]

also, for a backend language recommendation I'm going to go ahead and give you a very unorthodox option: side-server Swift, using a framework like Vapor. It has all the performance that you liked from Rust, but with a language that is vastly superior and more intuitive in just about every sense.

There’s a “sales-evening” once a week, Thursday in big cities and Friday in smaller cities, where shops stay open until 9. Grocery stores close anywhere between 6 and 10. And some other shops also stay open until 10. I don’t understand some of the logic here, but I guess it works.

Just as a couple others have said, rust is designed to be memory safe. The unwrap function isn't the intended way to get the value from the result - instead use the match statement to handle what happens that unwrap fails or not. Also regarding gradlie, have you seen the new kotlin dsl for gradle? Worth having a look at and brings gradle more up to modern standards. Great video as always marko!

[@bou3621]

Dude your videos are epic so is the city .

[@RamonBoorges]

Hey Marko! About the infra part of the product I think that the easiest way here is to go serverless. In AWS you have to the define the subnet where your lambda will be executed, and this way you can restrict to a specific availability zone to avoid GDPR issues and still be very scalable. The DNS can be solved with Route53 regional rules that depending from where the address of your service is requested it will be solved to a different API gateway (either in Europe or outside Europe). Regarding HTTPS you can even use ACM to sign the certificate and attach it to your API Gateway, and use cloudfront for caching the results. I would also go here with DynamoDB for scalability and ease of management. Also the price is super low when compared to other DBs and if the product grows a lot you can even make the tables global to decrease your time to info!

[@sabinhogui]

Hi Marko, nice video as always

[@embiem_]

For deployment, you could start with docker-compose which is great for local development as well as self-hosting. Then later can use the Kompose tool to quickly start using K8s for larger prod deployments.

[@maxolande7431]

K8s is very complicated lol. I’d suggest he uses Cloud Run because the containers scale up and down based on traffic.

[@kwadr4tic]

Every language has pros and cons, maybe the best thing to do is considering all the libraries which will make your project easier. If your project is Kafka-heavy then go with Java, or Scala. Almost every language supports Kafka as a message broker, with consumers and producers, but if you want to do many stateful operations, the kafka-streams library could save your day, and it's only Java (there are some ports around, but the java library is developed by the same team around Kafka). Considering the first two pieces of your architecture, the catch-all kafka writer and the ingress, I think that kafka-streams could be a good fit. For example, if you plan to implement rate-limiting based on messages, you could use kafka-streams time aggregations with just a couple lines of code. Moreover, kafka-streams offers you local storage which works like an embedded database on the services, and for persistent backups you could use the Kafka Connect API from a kafka topic into almost any persistence layer.

Wow… that is impressive research!

[@SavvasMohito]

Hi Marko! I recommend you go with AWS. I am currently using it on a project I work on and it's phenomenal. You can have all of your diagram components as AWS services. In terms of the GDPR, you can have different storage instances per region to keep the data in the same continent as the user. Unfortunately it cannot be self hosted though.

[@withmarko]

Hey thanks for the input. Yeah AWS is extremely powerful, I also used it in the past, I'll have to look into the regional instances, and what the legal language is around that 😃

[@Tayuzx]

Hello mark love watching the videos I know you have probably answered this before but I really like your bag that I see in your day in the life videos and was wondering what bag it is keep up the good work!

[@noob4head]

Hey Marko! First of all as always awesome content! Your production quality through the roof 🚀 Second I've got a quick question for you and my fellow coders: how do you stay pumped and interested in coding non-stop? Lately, I've hit a bit of a motivation slump. Coding isn't grabbing me like it used to, and when the college day comes to an end I'm spending more time playing games and watching shows/animes than on coding. How do you keep your motivation up? And do you maybe have some tips on how you can improve yourself as a programmer in general? Maybe this would make for an interesting video topic if that's something you are willing to do?

[@mermigkis]

Hey dude, we all go through these periods. Just thinking of a project and trying to implement it is what keeps you motivated all the time. That's what works for me at least. If I stop somewhere, I need to find a solution and it's all I'm thinking of.

[@karlembeast]

​@mermigkis I agree with you. Having one or more project(s) to work on definitely keep me motivated. But relying solely on motivation is tough. You have to be consistent (not only work on something when you have motivation). Personally, I found having accountability partner(s) helps with consistency. Having someone to discuss your project(s) with, share ideas, and ask for advise fuels the passion for coding.

[@skylerdjy]

The negative earnings with the laugh took me out. Such great content to start the day with :)

[@vinkomilotic9704]

Hi Marko, this recommendation I'm about to give may not be perfect but I believe it is still pretty good none the less (dunno how to spell it right :P). Anyways, since I see from the video that you really like and need good request paths handling and paths defining I highly recommend Nestjs (backend TypeScript framework) which I know "It's TypeScript which means it's slow and yada yada yada" but lemme tell you it's actually quite fast for a TypeScript framework (especially recently since they made a new feature which makes Nest 20x faster than before, still experimental). It is pretty easy to pick up and maintain the codebase. Also, Nest is made for big projects with a big amount of data flow. It is heavily reliant on dependency injection which is a double edged sword but in my experience I had no problems with it at all in Nest. When it comes to hosting honestly it really depends on you situation. If you need a server on demand with a specific amount speed and reliability then serverless is the way go to but don't take me seriously with this last one cause i still need to learn a thing or two about it. I hope I helped with your decision and good luck with the project :)

[@alex1431999]

At my company we have similar requirements to your project. It's self hostable, it's GDPR compliant and privacy focused. What we do is, we have a docker file for each component such that we can host the entire infrastructure on kuberenetes for our SaaS solution but we also provide a "all in one" image for selfhosters if they just want to get something up and running. Could be an idea for you as well? You could just start out with one image that encapsulates all of your components and once you need to scale you can figure out kuberenets.

Nice video Marko. Please what font are you using for your vscode?

[@h4kku]

Hey! Love your videos. As a web dev myself I am faced with issues relating to gdpr a lot. I had discussions and talks at length with lawyers and people who should know what they are doing but unfortunately because there are barely if any legal decisions/cases and the actual legal texts are very confusing in the ways they can be interpreted I would argue it's wrong to say google analytics is flat out "illegal" in the EU. Almost every big tech company nowadays is based in the US so even using things like Microsoft Office which is perpetually online now, any browser, etc would be "illegal" in the EU because they transmit data to the US. There are a few regulations like the "standard clauses" which handle these cases. I've been immersed in this topic a lot but unfortunately the tldr of the situation is, that it's just a big gray area with a lot of unkowns as of today. Unless we have actual cases that have decisions made by judges, there is no real "right" way atm. just a "probably correct, but it might also be wrong"-way...

Bun is out! It might be the perfect balance for using typescript and getting performance improvements

[@sordahl]

Great vlog, super authentic ... where did you get the beats used ?

[@seanbaeker4310]

Sounds like a great use case for CQRS when speaking of backups but you already have that part down. Language wise I would use Java with Quarkus which will make everything really really easy and maybe deploy to OpenShift if that is something you are comfortable with.

[@sahilsingh5695]

Points to consider 1) Its a personal project so I think not more than 2-3 people will work on this hence code maintainability will not be a bigger issue hence complexity of the language will not have that much of a impact 2) Since it will be a data analytics software therefore runtime minimization should be a major priority but I think that also depends upon the dataset, So you should have an idea about the size of the data so that can be a tradeoff with the language complexity

[@Anonymous-6598]

Honestly Mark, you should rather use typescript with some sql modules. Kafka is more for global and complex data analytics. I think that you should try scala as an option but try using some data frame in TS (like pandas in python).

I enjoyed your run through of each of the languages from your perspective. How about using C#? Similar syntax and feature set compared to Java but you get nullable referencing in newer versions (to help with catching NREs at compile time). You may be possible to implement your entire back end using PAAS or managed cloud services (such as Azure with Event Hub or AWS managed Kafka).

One thing about Kafka: You have to be sure that with Kafka you have to put in a lot of work manually also still in production if you want to scale up.

I like go compile times, almost instant for what i do. Feedback loop is great. Rust has a lot going for it, but for productivity i think go has many benefits. I also struggled with some of the stuff that was going on in Rust, which felt too complicated for what it actually achieved. On the other side go sometimes feels just too simple for me, not like a mature programming "environment" - but that may just be me after more than 20yrs in the Java department ;-) I would still use Java if my company would depend on it. If you have a bit of wiggle room go for go. If you can play around, have a lot of time *LOL* and special needs: Rust. I would avoid TS and JS at all costs, never liked these banana meme script kiddies "languages".

[@chimagamer4157]

as far as my shallow understanding goes, Data Science is about Statistics (gathering data, evaluating / processing data, presenting data), programming is how you apply, all the math, in production. You will sorta need both, because there is a reason people say, programming is just math, but practically applied.

I wonder why "serverless" for you automatically means "edge"? i'm relatively new in all those devops stuff and doing it only for a little for my own pet project, but as far as I understand at least aws serverless capabilities, you can deploy dynamodb (nosql) or aurora (sql) in the target region as your primary database and be gdpr compatible about data. then you can package your server as a serverless lambda and here you go fully serverless, cheap, scalable (with all the downsides of aws of course) and presumably good with gdpr... no? besides it i'm curious about if you want to be infrastructure-as-a-code? and if so how can it be achieved with services like hasura? how can you simultaneously and together deploy db on hasura and server elsewhere?
