15 June 2022: Canonical today announced that Ubuntu Core 22, the fully containerised Ubuntu 22.04 LTS variant optimised for IoT and edge devices, is now generally available for download from ubuntu.com/download/iot. Combined with Canonical’s technology offer, this release brings Ubuntu’s comprehensive and industry-leading operating system (OS) and services to a complete range of embedded and IoT devices.
Ubuntu Core, the Ubuntu flavour optimised for IoT and edge devices, has a new version available. With a 2-year release cadence, every new release is both an exciting and challenging milestone. Ubuntu Core is based on Ubuntu. It is open source, long-term supported (LTS), binary compatible and offers a unified developer experience. It allows developers and makers to build composable and software-defined appliances built from immutable snap container images.
If you are packaging your IoT applications as snaps or containers, you are aware of the benefits of bundling an application with its dependencies. Publishing snaps across different operating system versions and even distributions is much easier than maintaining package dependencies. Automated IoT software updates make managing fleets of devices more efficient.
Last May, KubeCon gathered multiple tech enthusiasts, students, professionals, and companies. The event highlighted various topics and insights on how to collaborate on pushing the boundaries of cloud-native computin One of our Engineering Directors, Mykola Marzhan, shared his knowledge about databases on Kubernetes at KubeCon, during a session organised by the DoK.Community. We’ve picked out some of the key highlights from the talk below.
IT leaders, engineers, and developers must consider multiple factors when using a database. There are scores of open source and proprietary databases available, and each offers distinct value to organisations. They can be divided into two primary categories: SQL (relational database) and NoSQL (non-relational database). This article will explore the difference between SQL and NoSQL and which option is best for your use case.
In the previous blog, SQL vs NoSQL Database, we discussed the difference between two major database categories. In a nutshell, the main difference between NoSQL and SQL is that NoSQL adopts a ‘right tool for the job’ approach, whilst SQL adopts a ‘one tool for all the jobs’.
A real-time system responds to events within a specified deadline. If the timing constraints of the system are unmet, failure has occurred. In the kernel context, real-time denotes a deterministic response to an external event, aiming to minimize the response time guarantee.
Managing a Kubernetes cluster is a complex endeavor. As demands on a cluster grow, increasing the number of deployed pods can help ease the load on the system. But what do you do when you run out of nodes to host those pods, or when the load decreases and some nodes are no longer needed? Manually adding or removing nodes is possible, but wouldn’t it be better if there was a way to automate that task? Fortunately, that’s exactly what the Kubernetes Autoscaler charm is for!
Technology plays a strategic role in the success of any organisation. Whether you’re part of an enterprise with thousands of employees across the globe or running a startup from the garage of your home, the success of the business comes down to how you consume technology. However, it’s not that straightforward, and IT decision makers usually have to make a lot of trade-offs when investing in technology.
Welcome to the concluding chapter of this journey on embedded Linux development with Ubuntu. We covered a lot of ground, so let us quickly recap what we learned so far. In Part I we introduced Snaps, software packages designed for the world of IoT. Snap packages isolate and encapsulate an entire application, increasing the security and stability of embedded devices. Snapcraft is the command-line tool to build snaps.
