  • 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.”

  • Semi-Official Google Drive Support For Linux Arrives, What's Next?
    Three years ago, when a user would attempt to download the Google Drive Sync Client, Google would bring them to the appropriate download page, which of course, is based off of the operating system that user is running on. If a user would attempt to download the Google Drive Sync Client while running on Linux, they’d land on a page where the message reads: “Not (yet) supported for Linux.” So, what’s the deal with Google not developing a sync client for Linux users, seeing as to how they build a lot of their things using Linux? There’s one simple answer to that, unfortunately. Windows is mainstream, so a lot of their focus is put on what a majority of people use. The bigger the market, the more money in their pockets, of course. But don’t fear, change is near!
