  • How Salesforce Secures Docker Containers

    Running Docker containers securely as part of a DevOps pipeline is a process that has many steps and requires diligence. That's the message coming from Cem Gurkok, lead information security engineer at Salesforce, in a session at the DockerCon 16 conference here.

    While containers do represent a somewhat different paradigm for developers, security professionals might have a different view.

  • DockerCon Showcases New Docker Release, Containers-as-a-Service Model

    Docker is one of the most hyped technologies in IT today, as containers have gone mainstream. At the DockerCon 16 event, which was held June 19-21 at the Washington State Convention Center in Seattle, 4,000 people gathered to learn and talk about Docker. Among the news coming out of the event was the release of Docker 1.12, which includes an integrated container orchestration capability referred to as Swarm mode. Docker CEO Ben Golub, meanwhile, said IaaS and PaaS either deliver too little or too much of what an organization needs, so he sees the emerging containers-as-a-service (CaaS) space growing, which is where Docker is aiming to play with its Docker Datacenter technology. Golub also announced a public beta of the Docker Store, which is a curated set of containerized applications that users can obtain, Also debuting was the public beta release of the Docker native application for Windows and Mac, opening up those products from the private beta that was first announced in March. Other public
    betas announced at DockerCon were Docker for Azure and Docker for AWS public clouds. The general idea with the new public beta releases is to provide more seamless, integrated experiences for users of specific platforms when using Docker. In a keynote at the conference, Docker founder Solomon Hykes claimed most people don't care about containers; they actually just really care about applications. In this slide show, eWEEK takes a look at some of the highlights of the DockerCon 16 conference.

  • Docker Datacenter Launched
  • Why Docker is Like Chicken Nuggets and Waffle Cones

    There is a lot of hype and some confusion in the world of IT today about precisely what Docker is and how it enables the emerging world of micro-services. At the Dockercon 16 conference this week in Seattle, there were many talks explaining Docker capabilities, but it was perhaps the Day 2 keynotes that explained it best with some exemplary metaphors.

    According to Keith Fulton, CTO at ADP, Docker is a lot like chicken nuggets and waffle cones (though not necessarily eaten together at the same time). ADP, one of the world's largest payroll processing firms, has over 630,000 clients. Fulton noted that ADP does more than just payroll today, and considered itself to be a Human Capital Management (HCM) firm, with services including recruiting and 401K planning.

IT runs on the cloud, and the cloud runs on Linux. Any questions?

A recent survey by the Uptime Institute of 1,000 IT executives found that 50 percent of senior enterprise IT executives expect the majority of IT workloads to reside off-premise in cloud or colocation sites in the future. Of those surveyed, 23 percent expect the shift to happen next year, and 70 percent expect that shift to occur within the next four years.

  • Nearly 1 in 3 Azure virtual machines now run Linux
  • What a Virtual Network Looks Like: Planning

    Network services don't spring up unbidden from the earth but rather they're coerced out of infrastructure in response to business and consumer opportunities. Every operations and management paradigm ever proposed for networking includes an explicit planning dimension to get the service-to-infrastructure and service-to-user relationships right. On the surface, virtualization would seem to help planning by reducing inertia, but don't you then have to plan for virtualization? How the planning difficulties and improvements balance out has a lot to do with how rapidly we can expect virtualization to evolve.

  • Democratizing Docker: Changing Containers' Competitive Landscape

    At DockerCon 16, approximately 4,000 attendees descended on the Washington State Convention Center in Seattle from June 19 to 21 to learn about and experience the phenomenon that is the Docker container ecosystem.

    The big news of the event came on the first day of the conference with the announcement of Docker 1.12 and its integrated orchestration system. In the keynote speeches and in multiple sessions that I attended, that new Swarm mode was a hot topic of technical and business discussion.

  • Sony Settlement Gives PS3 Owners $9 After Company Made Console Less Useful Via Firmware Update

    We've noted countless times how in the modern computing era, you don't really own what you think you own. You don't really own the music or books that can arbitrarily disappear on your devices, and you no longer really own a wide variety of hardware that can be dramatically changed (often for the worse) via firmware update months or years after purchase. If you're extra lucky, you'll shell out $300 for a piece of hardware that one year later simply won't work at all. With intelligent automobiles and the rise of the internet-of-not-so-smart things, that's more true now than ever.

    Case in point: back in 2010 we noted how Sony issued several firmware updates for its Playstation 3 gaming console that effectively made the console less useful. One specifically (PS3 software update 3.21) removed the console owner's ability to load alternative operating systems like Linux. But tinkerers being tinkerers, some users found ways to use the feature to expand the console's functionality in all kinds of creative ways. Fearing a loss of control and potential spike in piracy, Sony decided to make the console significantly less useful.

  • Serverless Microservices (and Minimal Ops): Current Limitations of AWS Lambda

    A “serverless” approach to API deployment involves containerization, webhooks, virtualization and reciprocity, with no infrastructure (servers, deployments or installed software) required. Microservices can be used as an abstracted resource that allows developers to work more effectively, and focus more on development and less on operations.

  • Microservices: What They Mean and How They Impact the Channel

    "Microservices" is fast becoming one of the newest buzzwords that IT decision makers need to know as DevOps redefines modern software application delivery. Here's a primer on what microservices mean and how the concept is affecting the channel.
