Life in a Post-Container World and Why Linux Will Play a Diminished Role

Filed under

Linux
Server

Containers have actually been with us since the late 1990s, but they are not the end of the story. The real transformation will come with a “serverless” future that will completely overturn the ops ecosystem. Companies will go out of business, new ones will spring to life, and thousands of people will have fundamental changes to their jobs. The shift to a serverless future is much bigger than your normal hype cycle — I believe the current container hoopla is a foreshock preceding a 9.0 quake.

30 Sys Admins to Follow on SysAdmin Day

Systems administrators: They keep our high-tech world up and running. From capacity planning, to 3 a.m. phone calls, to retiring that 10-year-old server that uses more power than your whole house, sys admins do it all. Open source communities would not be able to thrive without the networks, services, and tools that allow for communication and collaboration, and sys admins are the ones who work thanklessly year-round to keep them going.

July 31 is System Administrator Appreciation Day, a day for all of us to express our undying gratitude for sys admins. Sure, you could buy your favorite sys admin cake and ice cream, or perhaps a nice gift card. You could even go as far as not breaking the server for just one day. You also can follow these 30 sys admins.

  • Why Docker is Not Yet Succeeding Widely in Production

    Docker’s momentum has been increasing by the week, and from that it’s clearly touching on real problems. However, for many production users today, the pros do not outweigh the cons. Docker has done fantastically well at making containers appeal to developers for development, testing and CI environments—however, it has yet to disrupt production. In light of DockerCon 2015’s “Docker in Production” theme I’d like to discuss publicly the challenges Docker has yet to overcome to see wide adoption for the production use case. None of the issues mentioned here are new; they all exist on GitHub in some form. Most I’ve already discussed in conference talks or with the Docker team. This post is explicitly not to point out what is no longer an issue: For instance the new registry overcomes many shortcomings of the old. Many areas that remain problematic are not mentioned here, but I believe that what follows are the most important issues to address in the short term to enable more organizations to take the leap to running containers in production. The list is heavily biased from my experience of running Docker at Shopify, where we’ve been running the core platform on containers for more than a year at scale. With a technology moving as fast as Docker, it’s impossible to keep everything current. Please reach out if you spot inaccuracies.

  • A New SysAdmin Pledge in Honor of SysAdmin Day

    In fact, history is filled with examples of great people declaring a holiday for themselves. Take Christopher Columbus, for example. Upon discovering “The New World”, Columbus immediately declared the second Monday in October to be “Columbus Day” (to be celebrated with cake… and balloons… and confetti). It took a year or two to catch on, but before the decade was through, most of the world was already celebrating this new holiday. It's true. Look it up.

  • Getting friendly with open source: Big Data firm liberates proprietary chokeholds

    Enterprise customers could consider open source as the solution to their problems. According to Anand Venugopal, Impetus’ head of real-time stream analytics platform StreamAnalytix, “People have become so friendly to open source, and they have been waiting to be liberated from the hold of proprietary vendors that they are positively biased toward open source-oriented technology.”

    Discussing a recent use-case scenario, Kankariya said, “The guy was looking for his problem to be solved; he doesn’t care if it’s Hadoop or NoSQL or whatever.” This openness has allowed Impetus to become a trusted partner and advisor for customers that want to “cross-learn from across the ecosystem.”

  • Fedora repository for Doom stuff: Zandronum, Doomseeker, CnDoom
    I had a bit of free time over the last few days, and looked at the current state of the art for Doom on Linux. The awesome Rahul Sundaram has been looking after several Doom-related packages for a while – including the Chocolate Doom package – but there are some things that seem to be commonly used these days that we didn’t have packaged. So I packaged them up, and put them in a new repository!
  • CUDA 7.0 enabled programs for Fedora 22
    I’ve udpated the CUDA version in the Fedora 22 Nvidia repository, it now contains CUDA 7.0.28 along with the cuFFT 7.0.35 patch. Note that from this version, CUDA is x86_64 bit compatible only, so there are no more i386 packages. There is still the cudart library available for 32 bit, but I don’t think it’s worth packaging.
