Mender
Mender is an over-the-air (OTA) software and firmware update service, written by Northern.tech AS that delivers easy-to-use and high-quality solutions for hybrid and large-scale environments.
The goal of the project is to provide a simple and reliable solution to remote update and manage devices. It allows application of security patches, bug fixes, and new features to connected devices.
Mender can be used with a dual A/B rootfs approach so that embedded devices can recover from any error during the deployment, such as power loss or loss of internet connection.[1] This method relies on two root file systems, one inactive (ready to be updated) and one active (currently running). Integration with the bootloader ensures the correct root file system is being booted after an update is deployed, while still keeping the root file system that is known to be working as a fallback.
Mender also supports package updates, application updates, and container updates.[2]
Mender works with most Embedded Linux devices, and is easy to integrate with Yocto using the provided meta-mender layer. It also supports Debian family OS (including Raspbian) with the provided mender-convert tool.[3]
The project is an end-to-end solution that consists of a management server and client software[2] and is licensed under the Apache License Version 2.0.

History
Mender is one of two Northern.tech products, with CFEngine being the first one.
In 2016, many companies were shifting from data centers to the cloud and the team behind CFEngine decided that instead of expanding the product, they should develop a new product able to update OTA devices: Mender.
Mender 1.0 was announced at the Embedded Linux Conference (ELC) in Berlin in October 2016.
