In today’s world people still argue about what or who DevOps is. Some may say it is a person who writes CI/CD or manages cloud infrastructure, others claim that it is a culture and knowledge-sharing attitude. If you are reading this post, you most probably have your own opinion on that matter. There probably isn’t a single “right” answer to the question. Whichever way you understand “DevOps”, you need to use some specific tools, and in this article I’ll share some insights on how we handle our processes at Netguru. I could have just listed all common DevOps tools, but there are plenty of articles about that on the Internet, so let me focus on Netguru's way of using 5 selected tools. As a tasty starter let me tell you that some of those were developed internally! 

When you build a great product it will eventually attract more and more users who will expect performance and availability. As the app grows and over time it handles more requests per minute. If you’re not prepared for this, app performance will drop and you will potentially lose your audience.  This article will show you what to pay attention to when building a scalable app.

It’s amazing what happens when you ask a question 🔥 We asked businesses to share the biggest challenges with site migration – let me tell you, it’s a crazy mix of situations with some very real truths... And that’s what we want to talk about. The Public Cloud has opened up amazing possibilities. And it is changing the types of challenges businesses encounter. So, without further ado, let's see what they had to say:  

How can you avoid the headache of having multiple heavy features or services on your web app? You may add more resources or refactor, or perhaps pile up on external services – but that doesn't help when users come back with more requests for new features.  We look at how combining Node.js with Lambda AWS and Serverless can solve some of these problems. 

Most web applications are fundamentally similar – they get input from users then process and store it. The end result usually shows the processed input to users in the form of an output. These applications are usually called CRUDs – this means that the infrastructure (the core components that work together) needed to support a typical product can stay almost the same for most startups. This article will show you the core components and how to design your infrastructure in a way that it is efficient, scalable and cost-effective.

Reliability, performance and security are huge factors to consider when developing a product online.  They can determine the success or failure of your app – what good is all that app development just for it to get knocked offline? With challenges growing in complexity software development brings with it new demands.  What is an SRE and what value do they bring to a software development project? 

At some point, you will have to decide where to host your amazing RoR application. Choosing between dozens of excellent hosting providers might not be so easy as each provider has its own trade-offs in terms of price, deployment / configuration flexibility, and scalability to name a few. To make your choice easier, we have compared five major RoR hosting providers – depending on your application requirements and budget you can make the right choice about where to host your application. 

Serverless computing is a hot topic in software architecture – but is it just another overhyped tech-buzzword?  Or maybe this newcomer in the IT world is bringing with it a world of change. In this article we explain ‘serverless’ and answer the most important questions:

Have you ever wondered what is behind the success of a car assembly line? How they manage to optimise work and minimise waste, operating only on what brings value?

Can a single mistake of a software developer ruin an entire company? The answer is yes, but only if the software development company doesn’t know how to learn from its past mistakes and grow as an organisation.
