We are in the process of building a modern content platform to deliver our content through various channels. We decided to go with Microservices architecture as we wanted scale. Microservice architecture style is an approach to developing an application as a suite of small independently deployable services built around specific business capabilities. You can gain modularity, extensive parallelism and cost-effective scaling by deploying services across many distributed servers. Microservices modularity facilitates independent updates/deployments, and helps to avoid single point of failure, which can help prevent large-scale outages. We also decided to use Event Driven Architecture pattern which is a popular distributed asynchronous architecture pattern used to produce highly scalable applications. The event-driven architecture is made up of highly decoupled, single-purpose event processing components that asynchronously receive and process events.

To build our #Backend capabilities we decided to use the following: 1. #Microservices - Java with Spring Boot , Node.js with ExpressJS and Python with Flask 2. #Eventsourcingframework - Amazon Kinesis , Amazon Kinesis Firehose , Amazon SNS , Amazon SQS, AWS Lambda 3. #Data - Amazon RDS , Amazon DynamoDB , Amazon S3 , MongoDB Atlas

To build #Webapps we decided to use Angular 2 with RxJS

#Devops - GitHub , Travis CI , Terraform , Docker , Serverless

When you think about test automation, it’s crucial to make it everyone’s responsibility (not just QA Engineers'). We started with Selenium and Java, but with our platform revolving around Ruby, Elixir and JavaScript, QA Engineers were left alone to automate tests. Cypress was the answer, as we could switch to JS and simply involve more people from day one. There's a downside too, as it meant testing on Chrome only, but that was "good enough" for us + if really needed we can always cover some specific cases in a different way.

In our company we have think a lot about languages that we're willing to use, there we have considering Java, Python and C++ . All of there languages are old and well developed at fact but that's not ideology of araclx. We've choose a edge technologies such as Node.js , Rust , Kotlin and Go as our programming languages which is some kind of fun. Node.js is one of biggest trends of 2019, same for Go. We want to grow in our company with growth of languages we have choose, and probably when we would choose Java that would be almost impossible because larger languages move on today's market slower, and cannot have big changes.

Hi Community! Trust everyone is keeping safe. I am exploring the idea of building a #Neobank (App) with end-to-end banking capabilities. In the process of exploring this space, I have come across multiple Apps (N26, Revolut, Monese, etc) and explored their stacks in detail. The confusion remains to be the Backend Tech to be used?

What would you go with considering all of the languages such as Node.js Java Rails Python are suggested by some person or the other. As a general trend, I have noticed the usage of Node with React on the front or Node with a combination of Kotlin and Swift. Please suggest what would be the right approach!

Use the language which works well for the developers you have or have available. If you're starting, building a first iteration is far more important than worrying about what language might be best to solve a problem you may never have.

When hiring, look for developers, not "node developers" or "java developers" having people who recognise and are willing to adapt means you can have the flexibility you will need to solve as-yet unforeseen issues. Hire people who are wed to a specific language and you will be bound to that language, regardless of whether it's most appropriate or not.

Hey! Thanks for the response. I do agree with this line of thought, currently I do have an established team of Folks who are pretty good at NodeJS and related stacks (MEAN, MERN, Meteor etc.) along with expertise in Flutter, Native Apps along with AWS as well. I think this would constitute the core App and then integrations all across can take place. Would you have any reading material on the Serverless front in relation to Neobanks / Digital Banking platforms? Thank you.

For online banking, it'll be less computation intensive and more data intensive. So, Rails will be better than Python. I'll not recommend Node.js as it's not as scalable as those. If I had to choose indepently I would took Go.

What measurements do you base the scalability conclusion / comparison of python, ruby (rails), and nodejs on?

nodejs maintains concurrency by events, it's common sense that a single thread would never be able to equivalent of multi-thread.

Now, let's talk about Ruby vs Python.

Python requires the developer to be clean about side effects and isolation. With Ruby one can write concurrent programs that operate on multiple cores easily, similar to Python, a developer is responsible for side effects and isolation issues. Python’s concurrency process is more resource-demanding as compared to Ruby. But then again, it boils down to developer coding habits if one has to take the cake offered by both Python and Ruby Performance languages.

Seems like a banking system would have its scalability depend more on the transactional database in use, rather than the choice of language used for the api layer, which probably just translates from/to http+json or whatever transport and message standards used, to some atomic sql / db query in a transaction and serialising the response. Seem unlikely there would be any need for shared memory multi-threading in the api layer. Node.js could probably be used just fine, e.g. with PostGraphile on top of PostgreSQL. It seems very unlikely to be the bottleneck.

In case of online banking, bottleneck may occur. I'd rather prefer isolated hybrid database API, that'll better than PostGraphile. For security issues, I'll not recommend any GraphQL API in online banking application, also it'll not be helpful in this scenario. It's true that "a banking system would have its scalability depend more on the transactional database in use", but when it's about online banking it's not only about transaction, I bet, they've more to offer to their clients. So, scalability on api layer is also important for this case.

Brother I have been working in Ruby on rails and nodejs from last 3 years. From my experience it is easy to scale nodejs as compared to Ruby and it even requires less resources for deployment as well. This was one of the reason why linkedin shifted their stack from Ruby on Rails to Nodejs.

I have just started learning Python 3 week back. I want to create REST api using python. The api will be use to save form data in Oracle database. The front end is using AngularJS 8 with Angular Material. In python there are so many framework for developing REST ** I am looking for some suggestions which REST framework to choose? ** Here are some feature I am looking for * Easy integration and unit testing like in Angular we just run command. * Code packageing, like in Java maven project we can build and package. I am looking for something which I can push in artifactory and deploy whole code as package. *Support for swagger/ OpenAPI * Support for JSON Web Token * Support for testcase coverage report Framework can have feature included or can be available by extension.

What is the best MVC stack to build mobile-friendly, light-weight, and fast single-page application with Spring Boot as back-end (Java)? Is Bootstrap still required to front-end layer these days?

The idea is to host on-premise initially with the potential to move to the cloud. Which combo would have minimal developer ramp-up time and low long-term maintenance costs (BAU support)?

React might be a good option if you're considering a mobile app for the future, because of react native. Although, Vue.js has the easiest learning curve and offers a better developer ramp-up time. Vue.js is great to build SPAs, very clean and organized and you won't have a lot of long-term maintenance problems (like AngularJS, for example). Bootstrap can still be used, but with flexbox there's no need anymore.

React

I recommend React because of less memory occupant compare to Angular, but this will depend on your organisation flexibility. When you use React you need to import different libraries as per your need. On the other side angular is a complete framework.

Performance-wise I vote for react js as it loads up quickly and lighter on the mobile. You can make good PWA with SSR as well.

Visual Studio Code

The main contenders here are VS code and Eclipse, because Koding is meant to be used by large companies and by devs who know what they are doing. Both VS code and Eclipse have pros and cons, but for someone who wants to learn, VS Code is a much better choice as it has a very simple UI and plugins are easier to find and download.

Eclipse isn't meant for learning purposes and was designed with the intent to be used by professionals. Also it is an amazing IDE for java, but isn't so good in other languages, while VS code is much more efficient in a vast number of languages.

The only likely issue you might be facing with vs code is that, at times, it can be a resource hog, and in extreme cases it is possible to crash. But it is very rare and I recommend you have at least 8GB ram and at least a dual 1.6 GHz CPU.

Whenever Qualys scan finds out software vulnerability, say for example Java SDK or any software version that has a potential vulnerability, we search the web to find out the solution and usually install a later version or patch downloading from the web. The problem is, as we are downloading it from web and there are a number of servers where we patch and as an ultimate outcome different people downloads different version and so forth. So I want to create a repository for such binaries so that we use the same patch for all servers.

When I was thinking about the repo, obviously first thought came as GitHub.. But then I realized, it is for code version control and collaboration, not for the packaged software. The other option I am thinking is JFrog Artifactory which stores the binaries and the package software.

What is your recommendation?

I am trying to make Roblox game which requires Lua. I quite don't want to go with Lua just because other tools just might let me do more projects later on. I heard that Python is most similar to Lua, but I am still not sure which tool to use. Java, I think it will help me with many stuff later on for websites, projects, and more!

Since you are trying to make a Roblox game, you have no other option than to use Lua, since Roblox only allows coding in Lua. Yes, you've heard right, Python is identical and as easy as Lua, although Lua is easier than Python. Beginning from Lua and then escalating to Python is recommended. Java is only helpful when you are creating a heavy, big-budget, enterprise-level product, otherwise, Python would suffice.
