5+ Reasons to Use Selenium with Docker for Application Testing

// // by Suraj Vijayaraghavan

Application testing is a key element to make sure your web applications run smoothly, as it tells you whether the tested scenario works without a hitch and the features run as validated. High test coverage, code reviews and pull requests are required for a fast pace and high-quality code. Docker gives you the best of this because you can run your tests in containers or isolate them in development and deployment.

The Serverless Security Conundrum: Who Manages Security?

// // by Tal Melamed

The idea of ‘serverless’ is NOT about removing the servers completely (or you couldn’t use the internet at all), but essentially paying for services that mean that someone else manages the servers for you, thereby reducing maintenance load…

Not having access to the server can make things harder, but not impossible. And it’s not necessarily wrong, just different.

And the same applies to securing serverless apps. In some ways, it’s easier than securing traditional web apps. In other ways, it’s harder. And in yet other ways, it’s merely different. 

In this post, we’ll summarize these key differences and help you  secure serverless apps.

Testing Distributed Systems: Case Studies from the Pros

// // by Tamás Török

Figuring out how to test complex, distributed systems causes a lot of headaches. And the thing is, there is no one-size-fits-all answer. Distributed systems serve a specific need, so its architecture is built in a way to serve that business need. Chances are, the testing methods vary as well, and I haven’t even mentioned the number of independent services that also influences the testing methodology. 

Since it’s impossible to come up with a universal answer for testing distributed systems, we did interviews with 6 cool tech leaders to reveal their methods of testing. 

In this post, they will talk about how their systems work and the methods they use to test them.

Switching to a Microservice? Read this first

// // by David Dawson

microservice architecture is an interesting beast, as there is no real prescriptive definition of what makes one that is universal in nature. In my view a software architecture is much more akin to a form of software philosophy than any engineering discipline. In this post, David reveals his process for switching to microservices.

NoSQL vs Relational Database File Storing (MongoDB and SQL Server Comparison)

// // by Barna Burom

When you as a software developer start examining a new project’s specifications that just arrived at your team, you start planning the architecture. Every application uses data handling and storing, so you will need a database. Nowadays, there are tons out on the market, so you can become confused with which one to choose. Well, it highly depends on what your soon to be app is about. In this blog post, we will discuss the opportunities of file storing with relational and NoSQL databases through the comparison of MongoDB and SQL Server.

How to Easily Set-up Node Config Following These Best Practices

// // by Ákos Szokodi

When building any kind of server side app, you will eventually have the following thoughts:

  • I would like to bind my app to a specific port.
  • I would like to enter a connection string so I can connect to my database.
  • I would like to use a third-party service through a provided API key or credentials.

Given values to these kinds of parameters will yield a configuration. It is a crucial part of the system as our application will have lots of configurable elements, so it must be handled properly throughout the codebase.

In this article, we will look at the DOs and DON’Ts of Node config handling.

Beginner’s Guide to Serverless Architecture (Config, Deploy, Advantages)

// // by Dániel Vincze “Vinő”

Serverless is a software architecture where the code runs in the cloud but we don’t really know the OS and the hardware it uses. Everything is managed by the provider except the functions we upload.      

Serverless is not just an architecture. It is also a powerful framework we can use to develop and deploy serverless applications. After reading this guide, you will be able to deploy infinitely scaling NodeJS web application in minutes. Other supported languages are Java 8, Python 3.6 and 2.7, .NET Core 1.0.1 (C#)

Ensuring code quality when your software team is growing rapidly is a huge challenge. But even with a constant number of software developers, maintaining code quality can cause headaches.

Without tools and a consistent system, the whole project can accumulate a huge technical debt, causing more problems in the long-term than it solves in the short-term.

The best thing is that you don’t have to be a rocket scientist to avoid this (sure, it’s not a problem if you are one).
