Canonical’s chiselled Ubuntu containers increase efficiency by only providing necessary components in images

Canonical has announced that its chiselled Ubuntu containers are now generally available. These are ultra-small OCI images that just deliver an application and its runtime dependencies, leaving out things like operating system-level packages, utilities, or libraries. 

According to Canoncial, not including unnecessary components in the final image reduces bloat, increases efficiency, and reduces attack surfaces. 

Chiselled Ubuntu containers utilize a package manager called Chisel, which is based on the idea of package slices. Slices are subsets of Debian packages that contain their own content and dependencies.

“In the end, it’s like having a slice of Ubuntu – get just what you need. You can have your cake and eat it too,” the Chisel documentation states. 

Key benefits of chiselled Ubuntu containers include compatibility throughout the developer experience, fewer dependency issues, a CLI that allows customers to build or extend their containers, and simpler image rebuilds. 

“With Chiselled Ubuntu organisations can simplify their containerisation journey with a smooth transition from development to production,” Canonical wrote in a blog post. 

Chiselled Ubuntu containers come with security maintenance and support commitment from Canonical. Guarantees include five years of security patching for containers built from the main repository, 10 years of security patching for Ubuntu Pro customers, optional weekday or 24/7 support, and library and release cycle alignment with Ubuntu LTS. 

The images are available for a number of popular toolchains, including Java, .NET, and Python. As a result of a partnership with Microsoft, .NET 6, 7, and 8 already have images. 

“There has always been a need for smaller and tighter images,” said Richard Lander, program manager for .NET at Microsoft. “Developers remind us, as a base image provider, of that on a regular basis. Chiselled images leapfrog over approaches we’ve looked at in the past. We love the idea and implementation of Chiselled images and Canonical as a partner. When technical leaders at Canonical shared the first demos of Chiselled images with us, we immediately wanted to be a launch partner, and we’re thrilled that we’re shipping Ubuntu Chiselled images for .NET as part of this GA release.”

Difference between Web Designer and Web Developer Neeraj Mishra The Crazy Programmer

Have you ever wondered about the distinctions between web developers’ and web designers’ duties and obligations? You’re not alone! Many people have trouble distinguishing between these two. Although they collaborate to publish new websites on the internet, web developers and web designers play very different roles. To put these job possibilities into perspective, consider the construction of a house. To create a vision for the house, including the visual components, the space planning and layout, the materials, and the overall appearance and sense of the space, you need an architect. That said, to translate an idea into a building, you need construction professionals to take those architectural drawings and put them into practice. Image Source In a similar vein, web development and design work together to create websites. Let’s examine the major responsibilities and distinctions between web developers and web designers. Let’s get going, shall we? What Does a Web Designer Do?

2022: The year of hybrid work

Remote work was once considered a luxury to many, but in 2020, it became a necessity for a large portion of the workforce, as the scary and unknown COVID-19 virus sickened and even took the lives of so many people around the world.  Some workers were able to thrive in a remote setting, while others felt isolated and struggled to keep up a balance between their work and home lives. Last year saw the availability of life-saving vaccines, so companies were able to start having the conversation about what to do next. Should they keep everyone remote? Should they go back to working in the office full time? Or should they do something in between? Enter hybrid work, which offers a mix of the two. A Fall 2021 study conducted by Google revealed that over 75% of survey respondents expect hybrid work to become a standard practice within their organization within the next three years.  Thus, two years after the world abruptly shifted to widespread adoption of remote work, we are declaring 20
