Who doesn't like a clever turn of phrase? Docker CEO Ben Golub (pictured below) provided several from the recent Red Hat Summit in answering our questions about virtualization, Big Data, and DevOps.
With Cloud Expo now approaching, I see a lot of the big issues that will be raised there being raised here. Ben, take it away...
Roger: Could you explain for our audience the significance of containerization, and how it differs from virtualization?
Ben: Traditional virtualization was created over a decade ago, when applications were long-lived, monolithic, and deployed to a single server. In this world, when the problem to be solved was proliferation of single purpose physical servers - e.g. one server for Microsoft exchange, one server for Mac Print, one server for a custom Unix inventory -- it made sense to turn all of those single-purpose physical servers into single purpose virtual servers.
The VM was created, which takes an application measured in megabytes, combines it with a guest operating system measured in gigabytes, emulates disk etc., and creates a heavyweight, relatively static unit to run on top of a hypervisor.
Today, applications are short-lived and modified constantly. They are built from multiple loosely coupled components built on a multitude of stacks. And, they are deployed to large numbers of different servers.
Dockerization/containerization provides a much better alternative to virtualization for this kind of environment. Docker provides isolation, but in a lightweight format that runs directly on the host's operating system, and that can be easily modified or updated.
Docker enables containerized apps or components to work consistently together, work seamlessly across multiple different hosts, and do so with often 10x greater density than VMs. The same Docker container can be deployed, without modification, in milliseconds to a VM, to a bare metal server running RHEL, to a bare metal server running Ubuntu, to Amazon, to Rackspace, to an open stack cluster, etc.
So in my opinion, containerization and Docker have the potential to revolutionize how applications are built, managed, and deployed.
If you use an Android phone, you are already using containers. Every application on an android is containerized. Docker takes this concept to the far more complicated and sophisticated world of back-end data center applications.
Roger: How critical is the real-time aspect of modern IT? How quickly is it growing?
Ben: It's absolutely critical. Seconds matter in terms of time to deploy and update. Milliseconds matter in terms of scaling.
Docker enables customers to take a development>test>stage>deploy cycle that used to take weeks and shrink it to seconds or minutes. And, we make it possible to take applications and scale them and burst them across clouds in fractions of a second.
Roger: How key is the role of Big Data in developing your solutions? How important is the term Big Data to you?
Ben: Although we aren't a Big Data solution per se, we are a great solution for many big data problems. In Big Data application, the same application is rapidly scaled across hundreds or thousands of machines and often scaled down just as quickly.
A Docker container, which is lightweight, easy to modify, and easy to migrate to any server, is far more appropriate for a scale-out, performance sensitive, big data application than a VM.
Roger: How do the issues outlined above affect DevOps? What skills must organizations have to develop in this intense environment successfully today?
Ben: Today's organizations need to take complex and constantly changing applications and deploy them across complex and constantly changing production environments. Think of multiple applications, multiple versions, multiple components, and multiple languages being made to work across VMs, public clouds, private clouds, open stack clusters, and customer environments, and you quickly get what we like to call the matrix from hell.
This is compounded by the fact that you need to get a meeting of the minds between developers, who like to try new things and make changes; and operations, who like things consistent, repeatable, secure, and scalable.
Docker solves this problem by providing a clean separation of concerns. Developers can change things "inside" the container. But, the "outside" of Docker containers remains the same; all Docker containers stop, start, migrate, log, etc. the same way. This turns a DevOps nightmare into a DevOps dream come true.
P2P RTC will impact the landscape of communications, shifting from traditional telephony style communications models to OTT (Over-The-Top) cloud assisted & PaaS (Platform as a Service) communication services. The P2P shift will impact many areas of our lives, from mobile communication, human interactive web services, RTC and telephony infrastructure, user federation, security and privacy implications, business costs, and scalability. In his session at @ThingsExpo, Robin Raymond, Chief Architect at Hookflash, will walk through the shifting landscape of traditional telephone and voice services ...

We are reaching the end of the beginning with WebRTC, and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will want to use their existing identities, but these will have credentials already that are (hopefully) i...

WebRTC defines no default signaling protocol, causing fragmentation between WebRTC silos. SIP and XMPP provide possibilities, but come with considerable complexity and are not designed for use in a web environment. In his session at @ThingsExpo, Matthew Hodgson, technical co-founder of the Matrix.org, discussed how Matrix is a new non-profit Open Source Project that defines both a new HTTP-based standard for VoIP & IM signaling and provides reference implementations.

The definition of IoT is not new, in fact it’s been around for over a decade. What has changed is the public's awareness that the technology we use on a daily basis has caught up on the vision of an always on, always connected world. If you look into the details of what comprises the IoT, you’ll see that it includes everything from cloud computing, Big Data analytics, “Things,” Web communication, applications, network, storage, etc. It is essentially including everything connected online from hardware to software, or as we like to say, it’s an Internet of many different things. The difference ...

The security devil is always in the details of the attack: the ones you've endured, the ones you prepare yourself to fend off, and the ones that, you fear, will catch you completely unaware and defenseless. The Internet of Things (IoT) is nothing if not an endless proliferation of details. It's the vision of a world in which continuous Internet connectivity and addressability is embedded into a growing range of human artifacts, into the natural world, and even into our smartphones, appliances, and physical persons. In the IoT vision, every new "thing" - sensor, actuator, data source, data con...

Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using the URL as a basic building block, we open this up and get the same resilience that the web enjoys.

How do APIs and IoT relate? The answer is not as simple as merely adding an API on top of a dumb device, but rather about understanding the architectural patterns for implementing an IoT fabric. There are typically two or three trends: Exposing the device to a management framework Exposing that management framework to a business centric logic Exposing that business layer and data to end users. This last trend is the IoT stack, which involves a new shift in the separation of what stuff happens, where data lives and where the interface lies. For instance, it's a mix of architectural styles ...
