How to update a Docker container with Mender using Raspberry Pi
A Docker container packages applications in containers by virtualizing the operating system and dividing it into compartments to run applications. Powerful CPU-based devices can leverage virtualization to enable containers. Containers are easy to manage due to their atomic nature, enable more efficient use of system resources, faster delivery cycle and provide a nice layer of isolation. Microsoft...Read the article
Top three requirements for OTA software updates for IoT
Updating your device software, whether its system or application level, may seem an easy task to do when you first start your IoT project but then you realize what’s involved is more than just overwriting some files with new copies. What if the power goes out while the device is updating? What if the connectivity is lost due to poor network quality? What if a third party sends a fake update? What...Read the article
Managing large scale deployments with phased rollout and schedule deployments
As the number of connected devices increase, the operations and infrastructure needed to support continuous updates at scale is growing fast. Deploying to a large fleet of connected devices in the field with thousands or tens of thousands, can pose a significant risk of something going wrong.
Regardless of how well tested the software and update process is, you will only know how well the deployment works after it has been released into the field. Differences in time zones, network latency, hardware and customer usage patterns are all potential stumbling blocks preventing new software releases from behaving as expected. These factors can be impossible to predict. A failed update will result in negative customer experience and potentially high customer support costs. Worst case, collateral and brand damage might be at stake.
With the release of Mender Enterprise, feature such as phased rollout can help greatly mitigate the risk by deploying into time-delayed phases with customizable share of the devices being updated in each phase. Additionally, schedule deployments enable to set a start time for the deployment into the future, so customers are unlikely to be interrupted by the update, and your support staff does not need to be up at night to create and observe it.Read the article
How to do delta (differential) updates with Mender
Using binary deltas for applying updates is a more efficient mechanism for updating software over-the-air (OTA) which enables faster downloads and bandwidth cost saving for metered networks. When using cellular (e.g. 4G/LTE) or other bandwidth constrained networks, the impact is even greater. With the recently announced commercial editions, Mender offers the ability to generate and only deploy t...Read the article
Enabling faster downloads and lower bandwidth costs over cellular networks with Mender robust delta updates
Delta update is a more efficient mechanism for updating software over-the-air (OTA) when using cellular networks (e.g. 4G/LTE) which enables faster downloads and bandwidth cost savings. Mender offers the ability to generate and only deploy the difference (delta) between the software version already on the devices and the new version, on the binary level. Depending on the cellular technology and ne...Read the article
