The previous blog post talked about the composability of applications. The key element for composing applications is defining the relations between application elements. And supporting relations is one of the advantages of the Charmed Operator Framework – including its runtime, the Charmed Operator Lifecycle Manager.
Let’s remember the time in the 2000s when companies introduced their cloud computing offerings at a large scale. New services were put into the popular IaaS, PaaS, and SaaS categories. New kinds of storage and messaging technologies were promoted. Also, novel approaches were discussed, such as designing applications for horizontal scalability and eventual consistency.
Recently, I remembered a situation when I was in elementary school and visited a friend at his house. At some point, his mother wanted us to go to a neighbour and ask to borrow some eggs. We went a few houses down, opened the garden gate, entered through the door to the house, and arrived in the kitchen calling out for the person. But no one was at home, so we left and returned without eggs.
2021 has been an interesting year for the Kubernetes and cloud native ecosystem. Due to the pandemic, cloud adoption saw a big spike in adoption. As the year wraps up soon, we wanted to reflect on the top findings from the Kubernetes and cloud native operations report and we have a cool infographic for you. The new version of the report for 2022 is due some time in January so stay tuned!
If you’re looking for an alternative to Docker Desktop or to integrate Docker into your Multipass workflow, this how-to is for you. Multipass can host a docker engine inside an Ubuntu VM in a manner similar to Docker Desktop. That Docker instance can be controlled either directly from the VM, or remotely from the host machine with no additional software required. This allows you to run Docker locally on your Windows or Mac machine directly from your host terminal.
A year packed with news and events. A year where great competitions came to an end. A year that made us dream with new robots. 2021 inspired us to reach new heights and pursue new breakthroughs. As we power millions of robotics developers with Ubuntu and our robotics open source tools, we present a recap of what marked this year. Discover the victories and defeats of 2021. Those product launches that made the front page. Our best tutorials and whitepapers.
This blog post is part of our data centre networking series: With the explosion of application traffic and the multiplication of data centre workloads during the last decade, east-west traffic greatly increased and ended up impacting the traditional north-south based architectures. This raised the need to review the entire data centre architecture while keeping the goal of meeting performance, security, and monitoring requirements.
The Kubernetes crew at Canonical is delighted to announce that Canonical Kubernetes 1.23 is now generally available. The team is committed to releasing in tandem with upstream so our users and customers can benefit from the latest features and improvements as soon as they become available. This blog is a quick introduction to Canonical Kubernetes and the top features available in release 1.23.
Not all data is destined to be public. Moving workloads that handle secret or private data from an on-premise setup to a public cloud introduces a new attack surface with different risks. As the public cloud environment shares its hardware infrastructure, a flaw in the clouds’ isolation mechanisms can be detrimental to the protection of sensitive data. The major public cloud environments tackle this by building their security following a defense-in-depth approach.
If you are currently running the Robot Operating System 2 (ROS 2), this piece is especially relevant to the security of your robots. A few weeks ago, a group of security researchers reported 13 security vulnerabilities affecting some of the most used implementations of DDS, the default middleware used by ROS 2.
