Announcing Docker Cloud
Today we are proud to announce the immediate general availability of Docker Cloud. And we are excited to invite and welcome everyone of you to try it out. Docker Cloud is the name of the new cloud service by Docker that expands on the features of Tutum, brings a tighter integration with Docker Hub, and provides new updates and fixes.
In many ways, Docker Cloud is the manifestation of the generally available Tutum that users have been clamoring for, but Docker Cloud is much more than that. Over the past few months our team has been hard at work building native integration with Docker Hub, Docker ID (the new shared account system across all Docker services), Docker official repositories, commercially supported Docker Engine (CS Engine), and adding a new forum for all Docker Cloud discussions.
Docker Cloud is where developers and IT ops meet to build, ship and run any application, anywhere. With Docker Cloud you can easily:
- Deploy and scale any application to your cloud in seconds, with just a few clicks
- Continuously deliver your code with integrated and automated build, test, and deployment workflows
- Get visibility across all your containers across your entire infrastructure
- Access the service programmatically via a RESTful API or a developer friendly CLI tool
- and much more…
And we’re just getting started. The team is focused on delivering many new features over the next months. These include: adding collaboration capabilities for teams and organizations and continuing to expand the Docker platform capabilities available as a service in Docker Cloud.
To help you get started with Docker Cloud, we’re giving a free first node and private repository to everyone that logs in with their Docker ID at https://cloud.docker.com. We can’t wait for you to try it out for yourself, and experience how easy it is to manage all your applications and infrastructure using Docker Cloud. In order to make Docker Cloud universally accessible, it is being offered through a simple consumption-based pricing model. You’ll be happy to learn that additional nodes are available at only $0.02/node/hour (including email & in-app support).
We’d also like to take this opportunity to thank each and every one of our early beta users – without your support and feedback we wouldn’t find ourselves here today. Furthermore, we’d like to invite you to join us in congratulating the Docker Cloud team on reaching this milestone. And challenge them to continue building truly innovative software to improve how our customers build, ship and run their applications in the cloud.
Here are some resources to get you started:

Introducing Docker Cloud
This page introduces core Docker Cloud concepts and features so you can easily follow along with the tutorial.
The tutorial goes through the following steps:
- Set up your hosts by linking to a cloud service provider or your own Linux hosts.
- Deploy your first node cluster.
- Deploy your first service.
What is a node?
A node is an individual Linux host used to deploy and run your applications. Docker Cloud does not provide hosting services, so all of your applications, services, and containers run on your own hosts. Your hosts can come from several different sources, including physical servers, virtual machines or cloud providers.
What is a node cluster?
When launching a node from a cloud provider you’ll actually be creating a node cluster. Node Clusters are groups of nodes of the same type and from the same cloud provider. Node clusters allow you to scale the infrastructure by provisioning more nodes with a drag of a slider.
Using cloud service providers
Docker Cloud makes it easy to provision nodes from existing cloud providers. If you already have an account with an infrastructure as a service provider, you can provision new nodes directly from within Docker Cloud. Today we have native support for Amazon Web Services, DigitalOcean, Microsoft Azure, Packet.net, and IBM SoftLayer.
Using your own hosts (“Bring your own nodes”)
You can also provide your own node or nodes. This means you can use any Linux host connected to the Internet as a Docker Cloud node as long as you can install a Cloud agent. The agent registers itself with your Docker account, and allows you to use Docker Cloud to deploy containerized applications.
What is a Service?
Services are logical groups of containers from the same image. Services make it simple to scale your application across different nodes. In Docker Cloud you drag a slider to increase or decrease the availability, performance, and redundancy of the application. Services can also be linked one to another even if they are deployed on different nodes, regions, or even cloud providers.
Let’s get started!
Log in to Docker Cloud using your Docker ID. (These are the same credentials you used for Docker Hub if you had an account there.)

Introducing Docker Datacenter to Power Your On-Premises CaaS
Container service aims to support portability of apps across any infrastructure
29 Feb, 2016
Docker has unveiled its new container management offering, Docker Datacenter (DDC), designed to help organisations gain control over the creation, movement and administration of containers.
The product will allow organisations to deploy a Containers-as-a-Service (CaaS) either on-premises or in a virtual private cloud, the firm said. According to Docker, CaaS is an IT-managed and secured application environment where developers can, in a self-service manner, build and deploy applications.
The DDC is composed of the new Docker Universal Control Plane and Docker Trusted Registry, and also includes open source components such as Docker Engine, Swarm, Content Trust and Networking.
Solomon Hykes, founder and CTO of Docker, said that DDC is built upon “years of innovation” in Docker open source projects and ecosystem, and the feedback and experience of early adopters running Docker in production.
"Through Docker Datacenter, we ship an integrated, commercially-supported production environment for container workloads, bringing developers the agility they’ve come to expect from Docker-based applications, with a Docker-native application lifecycle where what they build is what runs in production,” he said.
“This provides IT pros with the level of control and security they need to manage an enterprise-class Container-as-a-Service platform, portable across any infrastructure, both on-premises and in the cloud.”
According to Docker spokesman Banjot Chanana, DDC is designed to work with the environment an organisation currently has, and provides the flexibility to adjust any part of that infrastructure without having to recode applications.
“As an example, the networking plugins make it super easy to use Docker to define how your app containers network together while choosing from any number of providers to provide the underlying network infrastructure,” he said in a blog post.
“This model enables a vibrant ecosystem to grow with hundreds of partners providing Docker users with choices in networking, storage, monitoring, workflow automation and much more.”

Cisco CTO: Containers will ride to private cloud's rescue. Oh yes!
Translation: We're touting services but please don't forget to buy our on-prem kit
3 Mar 2016
The emergence of containers will spark a renaissance for on-premises data centers, thus luring many businesses away from public cloud services, Cisco CTO Zorawar Biri Singh reckons.
Speaking at the Cisco Partner Summit in San Diego, Singh said he believes as much as 30 per cent of public cloud workloads will be going offline in the next five years as customers opt instead for local data centers based on container stacks.
Singh predicted that, as companies become more comfortable developing and deploying data centers with containers, larger deployments with public clouds will make less sense financially for many.
"It is very expensive at that scale, as IT practitioners see simpler container-based infrastructure come out, they will build more smaller container-based data centers," he said.
Singh notes that Cisco would, well, obviously stand to profit from such a trend, though he argues that, with its focus on networking and UCS, Switchzilla has less to lose from public cloud growth than other server vendors.
"There is a misperception that we are super exposed," he said.
"Overall port count decreases over time, but it is not as hard hit as compute and storage."
Singh's comments come as Cisco is embarking on its own efforts to transition itself toward a greater focus on providing broad enterprise IT services. Cisco, with some help from partners, has set its sights on selling customers everything from security to storage and analytics.
That transition, Singh argues, may not be the drastic makeover for Cisco that some pundits believe. He said that, instead, the shift is part of a natural growth for Cisco from its core networking business of shifting data from point to point to securing and analyzing that data as well.
Cisco pointed toward that shift this week with a crop of new product and service announcements focused on its HyperFlex and DNA lines.
"We know exactly where our revenue base is, we are investing more in software because it is a natural balance," he said. "There is nothing here that is a crazy leap."

HyperFlex - Cisco's new wave of converged hardware built with next-gen apps in mind
Mar 1, 2016
You can't build tomorrow's applications with yesterday's hardware -- nor should you build tomorrow's hardware for yesterday's applications.
That's the view Cisco seems to embody with its new data center switches and combined storage/network/compute HyperFlex system. These products are part of Cisco's larger vision of a cross-cloud fabric for running the next generation of microservices-based apps.
Starting from scratch
HyperFlex, an extension of Cisco's Unified Computing System (UCS) design, is aimed at enterprise customers who plan to deploy applications across data center and branch office environments. Cisco claims a HyperFlex stack can be set up in minutes and can perform "flexible, adaptive, and independent" scaling of compute, network, and storage.
To accomplish this, Cisco decided it couldn't leverage existing file system technology. Todd Brannon, director of product marketing for Cisco UCS, described in a phone conversation how Cisco partnered with SpringPath to build it. The new log-structured object file system isn't a repackaging of existing work like Red Hat's Ceph, Brannon said, but is something entirely new built from the ground up.
A key advantage of this, according to Cisco, is the capability to distribute and tier all of the data in a cluster to eliminate data locality problems that manifest with modern applications.
"With containers, there's a lot of 'stickiness' with the data," said Brannon, meaning that containerized apps (and VMs) need their data close at hand to perform well. HyperFlex allows data to be distributed across an entire cluster at once, so if a container or VM needs to move, "their egress into the storage environment is identical no matter what node of the cluster they're on," he said.
Another reason for taking a from-scratch approach was to be able to provide deduplication, compression, and cloning functionality -- but without the usual performance tradeoffs. "If you flip on dedupe and compression on some of the other solutions out there, their performance really tanks," said Brannon, who declined to name names.
Cisco also wants to keep the management learning curve low, so HyperFlex launches with support for VMware by way of a vCenter plug-in. Support for other hypervisors is slated for the future, and while an actual application-addressable object store will not be available at launch, "the potential is there for it," according to Brannon.
A better backbone
HyperFlex is intended to underpin a hybrid cloud environment that spans local and remote data centers. Networking is needed to accomplish that, and so Cisco has also unveiled a new generation of Nexus-brand switches.
Speed isn't the only goal with the Nexus 9000 -- although Cisco claims it can deliver 100Gbps, with better performance at half the cost of the competition. Transparency and manageability are advantages that Cisco sees as even more relevant.
"Consolidation of workloads on a single fabric requires better visibility," Thomas Scheibe, senior director of product management for Cisco ACI, said in a phone interview.
As applications become increasingly distributed and lean toward a microservices design, the network becomes more of the bus for the application than the compute layer. Being able to have real-time visibility and control over the network, at a full 100Gbps wire rate, is "not just for things like troubleshooting, but [for] capacity planning," Scheibe said.
The next steps up (and out)
There's little question that Cisco has the networking chops for a project of this breadth. Other startups that deal in hyper-converged architectures might have innovative ideas for storage and compute, but there are few other hardware companies with Cisco's pedigree in networking. Plus, UCS has been successful enough to rank fourth in the worldwide server market.
Next up is for Cisco to use HyperFlex as part of a larger strategy for multi-cloud (read hybrid cloud) application deployments -- where the network is a crucial component in how applications are orchestrated, as Cisco's new CTO, Zorawar Biri Singh, described recently. The details remain vague, though; Cisco's previously announced "Intercloud Initiative" hasn't been discussed in detail since Chuck Robbins became CEO nine months ago.
But earlier today Cisco announced it had acquired CliQr, a cross-cloud application deployment company (reviewed favorably by InfoWorld's Martin Heller), which could be a major hint of where things might be headed . As it did with SpringPath, Cisco isn't shy of bringing in outside expertise to help build its new vision -- whatever form it eventually takes.
