Edge computing - A story of buses, raspberries, IoT and API gateways

by Albert Lombarte · May 1, 2018

The IoT industry has been running for some years now adding millions of devices into the network. The range of devices and capabilities is very wide and heterogeneous, from small devices powered with a 9-volt battery to track the location of freight shippings traveling the oceans (using platforms like Sigfox) to permanently plugged devices with more powerful computing like a Raspberry Pi where computation cycles are not a problem.

How to work with Golang plugins and KrakenD

by Daniel López · Apr 12, 2018

The release of golang 1.8 more than a year ago opened the door to loading dynamic linked components in run time, and we were keen to find out if we could include this great feature in our KrakenD toolbox. We’d like to share our experience and details on how we enhanced our products to support golang plugins. Why would anyone use plugins in Go? The plugin concept is widely known and supported in several programming languages and environments. Continue reading →

Deploying and versioning an API Gateway

by Daniel López and Albert Lombarte · Apr 6, 2018

When it comes to maintaining and deploying an API Gateway within an organization, you should always be aware of best practice. A gateway is an extra step between the client and the servers with the power to define a whole new interface, yet it’s so flexible and easy to implement that you might be tempted to start creating API interfaces without thinking about it - and end up creating problems for the future.

An API Gateway is not the new Unicorn

by Daniel Lopez and Albert Lombarte · Jan 19, 2018

The more we talk to people about API gateways, the more we have come to realize that the term means different things to different people, and more specifically we see a growing trend where developers (but mostly managers) expect an API gateway to be able to perform miracles, usually a long way away from its intended use. It’s as if the API Gateway is the new unicorn that will solve all problems and make everything wonderful in the microservices scene. Continue reading →

Road to KrakenD 0.4

by dlopez · Nov 12, 2017

The next iteration of KrakenD is right around the corner and the Devops Faith team and the rest of the community we are working together to launch the 0.4 release before end of year. The jump from the 0.3.9 of the binary and the 0.3 of the framework to the 0.4 will bring a lot of interesting stuff but we also need to do a remarkable change in the code for a brighter future: kill external dependencies with fire.

How we automated our RPM and DEB packaging with Docker

by taik0 · Nov 6, 2017

Everyone loves reaching the maximum number of available platforms for their software but this usually comes at a cost. In this article we will explain how we generated our packaging for Linux in an automated fashion, being faithful to our DevOps dogma. Dockerize all the things! Our team uses both Ubuntu and MacOS X in desktop machines and KrakenD has been running and behaving in the same way in all the platforms because from day one we decided to run everything on Docker.

In this post we will explain the reasons behind this decision that might sound crazy from a business perspective in the first place.
