Docker and OpenStack By @BlueBox | @DevOpsSummit [#DevOps #Docker #OpenStack]

Docker--an open source technology--is as fresh and cool now as OpenStack was a few years ago

When OpenStack aficionados gather in Vancouver in a couple of weeks, one of the hot topics will be containers, a "new" alternative to virtualization. Actually, container technology has been around for a couple of decades, but it is trending among the IT community at a fever pitch these days and stands to have a huge impact on the future of cloud computing.The appeal of container technology is easy to appreciate. In a nutshell, containers can enable you to run many more applications on the same hardware than using hypervisors and virtual machines, and they can greatly enhance the application development process with their portability and almost instantaneous startup time.

One of the hottest container technologies is Docker. Docker--an open source technology--is as fresh and cool now as OpenStack was a few years ago.

Docker...

Described in simplest terms, Docker offers a lightweight way of packaging application code. A Docker container wraps up in a neat, portable package all the elements necessary to run an application, including many of the key components of the operating system. With containers' clever filesystem layering and unvirtualized access to resources, you can run many more containers--some say four to six times as many--on the same hardware as compared to the traditional use of hypervisors and virtual machines. Translation: You can use Docker technology to run oodles more apps and run them more efficiently on your same data center. Bottom line: significant cost savings.

Docker...

Plus, Docker containers are an app developer's dream because they greatly simplify the process of building, testing and deploying applications. Docker containers spin up rapidly and enable apps to be easily packaged, ported and run across machines virtually anywhere, including OpenStack clouds. These characteristics when used well can increase your velocity and reduce the time it takes to take features from development through to production.

OpenStack!

Of course, you still need a cloud infrastructure management environment in which to orchestrate all those app containers, manage authentication, monitor physical infrastructure performance, attach to storage, provision networking, etc. Thus, the combination of Docker and OpenStack is the equivalent of a cloud powerhouse; all the tools and technologies for application development, deployment and lifecycle management.

Maturing rapidly and battle hardened, OpenStack is the perfect platform from which to run legacy and agile apps, whether you're running them on bare metal, traditional VMs or Linux containers. I look forward to digging into this topic at the OpenStack Summit Vancouver and hope you'll join me for "Docker Docker Docker OpenStack."

Tuesday, May 19
3:40 - 4:20 pm
Room 114/115

In this session, I'll describe a number of different ways to run Docker on Openstack (or Openstack on Docker, if you're truly crazy) and discuss the pros and cons of each method. We'll also discuss ways to operationalize Docker on OpenStack, and then, just for fun, we'll bust a few myths by exploring how existing legacy applications can benefit from being containerized. Read more about the agendahere.

I look forward to seeing you in Vancouver!

The Kubernetes vision is to democratize the building of distributed systems. As adoption of Kubernetes increases, the project is growing in popularity; it currently has more than 1,500 contributors who have made 62,000+ commits. Kubernetes acts as a cloud orchestration layer, reducing barriers to cloud adoption and eliminating vendor lock-in for enterprises wanting to use cloud service providers. Organizations can develop and run applications on any public cloud, such as Amazon Web Services, Microsoft Azure, Red Hat OpenShift and Google Cloud Platform.
Because Linkerd is a transparent proxy that runs alongside your application, there are no code changes required. It even comes with Prometheus to store the metrics for you and pre-built Grafana dashboards to show exactly what is important for your services - success rate, latency, and throughput. In this session, we'll explain what Linkerd provides for you, demo the installation of Linkerd on Kubernetes and debug a real world problem. We will also dig into what functionality you can build on top of the tools provided by Linkerd such as alerting and autoscaling.
With container technologies widely recognized as the cloud-era standard for workload scaling and application mobility, organizations are increasingly seeking to support container-based workflows. In particular, the desire to containerize a diverse spectrum of enterprise applications has highlighted the need for reliable, container-friendly, persistent storage. However, to effectively complement today's cloud-centric container orchestration platforms, persistent storage solutions must blend reliability and scalability with a simple, cloud-native user experience. The introduction of Elastifile's CSI driver addresses these needs by augmenting containerized workflows with highly-available, scalable NFS file storage delivered via Elastifile Cloud File System...and with no complex, manual storage provisioning required.
Applications with high availability requirements must be deployed to multiple clusters to ensure reliability. Historically, this has been done by pulling nodes from other availability zones into the same cluster. However, if the cluster failed, the application would still become unavailable. Rancher’s support for multi-cluster applications is a significant step forward, solving this problem by allowing users to select the application and the target clusters, providing cluster specific data. Rancher then initiates deployment to those clusters.
Implementation of Container Storage Interface (CSI) for Kubernetes delivers persistent storage for compute running in Kubernetes-managed containers. This future-proofs Kubernetes+Storage deployments. Unlike the Kubernetes Flexvol-based volume plugin, storage is no longer tightly coupled or dependent on Kubernetes releases. This creates greater stability because the storage interface is decoupled entirely from critical Kubernetes components allowing separation of privileges as CSI components do not need full privileges of Kubernetes components. With the implementation of Container Storage Interface (CSI), persistent data layer for Kubernetes and other Container Orchestration (CO) tools, such as Mesos and Docker Swarm are now future-proofed.
