Canonical Enhances the Reliability of Its Kubernetes for IoT, Multi-Cloud & Edge

Filed under
Ubuntu

MicroK8s is an upstream Kubernetes deployment certified by the Cloud Native Computing Foundation (CNCF) and developed entirely by Canonical to run offline on your workstation or edge device for all your development, prototyping, and testing needs. MicroK8s is delivered as a snap, which makes it possible to run all Kubernetes services natively and comes bundled with all the libraries and binaries required.

The latest MicroK8s 1.16 release adds high-availability clustering by integrating enterprise SQL database through Canonical's in-house built Dqlite distributed SQL engine to enable rapid deployment of highly standardized small K8s clusters. Dqlite is designed to reduce memory footprint of the cluster in MicroK8s by embedding the database inside Kubernetes itself.

Canonical enhances Kubernetes reliability for edge, IoT

  • Canonical enhances Kubernetes reliability for edge, IoT and multi-cloud

    Canonical today announced high-availability clustering in MicroK8s, the workstation and appliance Kubernetes, and enterprise SQL database integration for its multi-cloud Charmed Kubernetes.

    “The rapid rise of enterprise and edge Kubernetes creates a challenge for corporate IT, with thousands of edge nodes running Kubernetes, and hundreds of cloud Kubernetes clusters,” said Stephan Fabel, Director of Product at Canonical. “The next generation of Canonical’s Kubernetes offerings reduce the number of moving parts, and embrace standard corporate SQL databases for Kubernetes data stores, to address the operational consequences of Kubernetes cluster sprawl.”

    Canonical’s MicroK8s gained popularity as an IoT, appliance and developer workstation Kubernetes, with a very small footprint suitable for edge devices and laptops. MicroK8s 1.16 added clustering, enabling rapid deployment of highly standardised small K8s clusters. The next step is to ensure high availability of these clusters, using Canonical’s Dqlite distributed SQL engine. Dqlite removes process overhead by embedding the database inside Kubernetes itself, and reduces the memory footprint of the cluster which is important for IoT.

  • New HA clustering on MicroK8s eases path to clustered edge appliances

    Canonical announced high availability clustering in MicroK8s, its single-node Kubernetes environment for prototyping k8s applications and running edge containers on IoT gateways. The feature is enabled using Dqlite.

    Last month with the release of Ubuntu 19.10, Canonical announced “strict confinement” support for Canonical’s MicroK8s Kubernetes environment for single-node clusters, thereby enabling easier deployment on edge devices. Now, Canonical has announced high availability (HA) clustering in MicroK8s.

    High availability clustering enables a group of hosts that act like a single platform. It’s often used to ensure continuous uptime via load balancing, backup, and failover strategies. All the HA-clustered hosts need to be able to access the same storage.

    In the last couple of essays I described some of the parts of a SDF record then pointed out some of the ways to break simple SDF record tokenizers.

Games: Unity, Super Slap Sisters, Ayo the Clown and Steam News Hub

  • Unity 2020.2 Bringing Some Hefty Performance Optimizations [Ed: Microsoft Mono unfortunately]

    Not only did Unity Software experience a successful IPO last week but they also rolled out the Unity 2020.2 engine into public beta and with that comes some "major speed-ups" for performance.

  • Super Slap Sisters [Ed: Requires WINE]

    These are some great additions that allow for an even wider variety of playstyles, keeping your opponent guessing as to when the best time to strike is. For example, not only can the clutch be used during an attack to throw your opponent off, it can also be a lifesaver just as you’re about to reach the blastzone (knockout boundaries) after getting hit. The clutch will reverse your momentum, meaning that the sooner you perform the clutch after flying, the closer you’ll get to the stage and therefore have a more successful recovery. Players who are new to this type of fighting will not be left in the dark here, as there is a great tutorial mode. The tutorial is very interactive with the player, giving them everything they need to get a basic grasp on how the game works. You can also read about the various mechanics that are available in-game, what they do, and how to do it, as well as get a bio on each character and what their moves entail.

  • Go on an epic quest as a not-so-average clown trying to find their dog in Ayo the Clown

    Ayo the Clown is an upcoming adventure platformer from developer Cloud M1, it should be releasing this year and it looks so full of charm it could pop like a balloon at any moment. Funded on Kickstarter back in September 2019 with 475 backers pledging $20,397 we totally missed this, it even had a Linux demo back then too. Cloud M1 said their take on the busy platformer genre is one that's supposed to "reintroduce you to the incredibly fun platformer games of the ‘90s where platforming is accompanied by an inspiring and memorable story". It has a pretty amazing style, one you can easily say is quite Nintendo-like.

  • Valve rolls out News Channels onto Steam to follow your favourite curators - like us!

    Over time Steam continues to grow as much more than just a games store, and Valve are showing how today with their next Steam Labs experiment to let you get your news. Steam Labs Experiment 009 announced here is an addition to the News Hub, which is now hooked up with the Steam Curator system. Valve said it's now nearing completion and it's a big stop towards the full launch. This will presumably replace the old Steam news feed.

Vulkan Graphics: Vulkan Portability Extension and More

  • Vulkan Portability Extension 1.0 Now Shipping For Expanding Vulkan's Reach

    The Vulkan Portability Extension (VK_KHR_portability_subset) has been released as part of the effort by The Khronos Group in getting Vulkan running on as many platforms as possible, including the likes of Apple macOS/iOS. The VK_KHR_portability_subset extension is about getting Vulkan up and running on non-Vulkan APIs, as opposed to the success we have already seen in areas like getting OpenGL or Direct3D atop Vulkan. The VK_KHR_portability_subset extension makes it easier for the likes of GFX-RS and MoltenVK for getting Vulkan running on platforms like Apple's operating systems where Vulkan is not supported and thus having to reside on top of say the Apple Metal API.

  • Mike Blumenkrantz: Dynamism

    In Vulkan, a pipeline object is bound to the graphics pipeline for a given command buffer when a draw is about to take place. This pipeline object contains information about the draw state, and any time that state changes, a different pipeline object must be created/bound. This is expensive. Some time ago, Antonio Caggiano did some work to cache pipeline objects, which lets zink reuse them once they’re created. This was great, because creating Vulkan objects is very costly, and we want to always be reusing objects whenever possible. Unfortunately, the core Vulkan spec has the number of viewports and scissor regions as both being part of the pipeline state, which means any time either one changes the number of regions (though both viewport and scissor region counts are the same for our purposes), we need a new pipeline.
