Quite recently, we've figured out that we can improve our internal flow in terms of answering clients' calls, coming primarily from abroad. The idea was to build a simple app that will intercept incoming calls, post a Slack notification and allow us to answer these calls through a web browser using Twilio number. That’s how Callio was born. In this article, you will find a comprehensive guide on how it works and how to integrate it with your account.

Does using docker to reduce disk clutter and time spent on setting up a new machine sound good? It definitely did to me. In this article, I’ll show you how to get started with a dockerized development environment, so you can get a taste of what it’s like. I’ll also give you some suggestions near the end on how to learn what you need to know about this tool.

GraphQL is a fairly new technology that will let you adjust your data requirements on the fly and increase the efficiency of your app while keeping your current stack.

Managing Amazon Web Services is hard, let’s face it. AWS is complex, offers numerous amount of services & APIs, it’s constantly changing, web console UX is bad and some concepts behind it are just hard to understand at the beginning. But once you start getting it, you also realize that it has a great power. The power not only to store unlimited amounts of data, handle millions of requests per second or even to predict your next partner using Machine Learning but also the power to literally clean your wallet in couple of seconds. It may be because of your lack of understanding of this system, because of a „miss click” or simply because you didn’t care to secure your account properly. Internet is full of stories like that. In this guide I’ll try to show you some “quick wins” which should decrease the probability of those events taking place.

Ever since its initial release – way back in 2009, would you believe – Node.js has been attracting the attention of developers the world over. And for a good reason. Written in JavaScript, this open-source, cross-platform environment makes Node.js a stand-out choice for real-time applications.

With the growing number of projects and required resources, my ongoing AWS management became more and more of an uphill struggle. That's why I began looking for a better solution than repetitive commands and clicks, keeping in mind the current trends in DevOps environment.

In Netguru, we like to work with different technologies to create advanced web applications. This time, we would like to put the spotlight on Node.js, a JavaScript runtime that our apps use as backend. It proved to be an efficient solution for real-time applications or the cases when a fast and scalable environment was required.

As Ruby on Rails developers, we have used AWS for a long time at Netguru. Amazon’s services such as S3, EC2 or RDS made our work not only easier and more convenient but also increased the security of many projects. A few months ago, during re:Invent 2016, which took place in Las Vegas, Amazon launched a new service, and we think we are all going to fall in love with it. The new service is AWS Lightsail.

Yesterday, some of us, developers, were hit hard by the AWS outage. Many websites went down for a few of hours, some of us couldn’t even continue working on your projects due to the outages of services like CircleCI.

When we’re building an app, we sometimes have to choose tools to help us manage servers and make our life and work easier. At Netguru, we work on many applications, and we manage a lot of servers, so here we present a list of tools we use on a daily basis - tools which we like and would recommend using.
