Server: Ubuntu Server, Canonical's Embrace of Buzzwords and LF on Storage

Filed under
Server
  • Ubuntu Server development summary – 11 September 2018

    Cloud-init version 18.3.39 adds jinja template support for user-data scripts and cloud config. As part of this feature, any cloud metadata crawled by cloud-init is presented as template variables. Any cloud-provided metadata such as ip addresses, hostname, region, availability_zone can be referenced in user-data cloud config or scripts without having to crawl and parse metadata in separate tooling.

    Since cloud-init generalizes some of this instance metadata across all clouds, it now allows user-data to be more flexible when deploying to different cloud platforms. See Using instance metadata for more information.

  • What is multi-cloud?

    Tech companies, Canonical included, have a problem. That problem is living in buzzwords and jargon, and then assuming everyone knows what we are talking about.

    At Canonical we call them ‘Canonicalisms’, other companies have their own names for it.

    Whilst we can joke about it, this over-reliance on jargon is a genuine barrier to our audience, developers, customers, people in need of technical help, people in need of assistance in understanding what all these buzzwords are. The jargon is a barrier to people understand what something like the cloud is, in its many different guises, and how these different architectures and strategies can be used for tangible business benefits.

    Fortunately, that’s a problem which is solvable.

    Canonical has decided to produce a whitepaper that details everything you need to know to understand every type of cloud from public to private and managed to multi-cloud. But, we haven’t stopped there, because these technologies don’t live in a bubble, they’re connected to technologies such as Kubernetes, containers, serverless computing, servers and virtual machines.

    Still, understanding the basics about these different technologies is only a piece of the picture, which is why we’ve also included guidance on the best strategies to use, use cases, when and where to deploy and make it a success.

  • Know Your Storage: Block, File & Object

    Dealing with the tremendous amount of data generated today presents a big challenge for companies who create or consume such data. It’s a challenge for tech companies that are dealing with related storage issues.
