Working on Triton in the lab, what’s on the horizon

January 27, 2016

As we’ve talked about before, a few of us in Dell’s CTO group have recently been working with our friends at Joyent.   This effort is a part of the consideration of platforms capable of intelligently deploying workloads to all major infrastructure flavors – bare-metal, virtual machine, and container.

Today’s post on this topic comes to us complements of Glen Campbell — no, not that one, this one:

Glen has recently come from the field to join our merry band in the Office of the CTO.  He will be a part of the Open Source Cloud team looking at viable upstream OSS technologies across infrastructure, OS, applications, and operations.

Here is what Glen had to say:

What’s a Triton?

Joyent’s Triton Elastic Container Infrastructure, a Private Cloud variant of the Joyent Elastic Container Service PublicTriton slide

Cloud, allows customers to take advantage of the technologies and scale Joyent leverages in their Public Cloud.

On the Triton Elastic Container Infrastructure (which I’ll call “Triton” from now on) bare-metal workloads are intelligently sequestered via the use of the “Zones” capabilities of SmartOS.   Virtual machines are deployed via the leveraged KVM hypervisor in SmartOS, and Docker containers are deployed via the Docker Remote API Implementation for Triton and the use of the Docker or Docker Compose CLIs.

What’s the Dell/Joyent team doing?

As part of interacting with Triton we are working to deploy a Dell application, our Active System Manager (ASM), as a series of connected containers.

The work with Triton will encompass both Administrative and Operative efforts:

Administrative

  • Investigate user password-based authentication via LDAP/Active Directory
    • in conjunction with SSH key-based authentication for CLI work

Operative

  • Use of:
    • Admin web UI and User Portal to deploy single/multi-tier applications
    • Joyent Smart Data Center (SDC) node.js client to deploy from remote CLI
      • Newer Triton node client to see next-gen of “sdc-X” tools
  • Docker Compose
    • build a multi-tier Docker application via Docker Compose, deploy on Triton via its Docker Remote API endpoint
  • Triton Trident…
    • deploy a 3-tier application composed of:
      • Zone-controlled bare-metal tier (db – MySQL)
      • Docker-controlled container tier (app – Tomcat)
      • VM-based tier (presentation – nginx)
    • Dell Active System Manager — a work in progress
      • aligning with Dell’s internal development and product group to establish a container architecture for the application

Stay tuned

Our test environment has been created and the Triton platform has been deployed.  Follow-on blog posts will cover basic architecture of the environment and the work to accomplish the Admin and Ops tasks above.  Stay tuned!

Installation details for Joyent’s Triton — Dell CTO lab

January 20, 2016

Here is our third and final post walking through the setting up of the Joyent Triton platform in the Dell CTO lab.  In the first post, Don Walker of the CTO office gave an overview of what we were doing and why.  The second laid out the actual components and configuration of the platform.

Today’s video is a walk-through of the installation process where Don shares his experience in setting up the Triton Platform.

When we pick this series up again it will focus on containerizing Dell’s Active System Manager and then loading it on Triton.  Not sure how long this work will take so stay tuned!

Some of the ground Don covers:

  • Before installing Triton, you need networking set up and working.  Don double clicks on the network configuration and what we did to make sure it was working.
  • Step one in installing Triton, is to create a bootable USB key and install the head node.  There is a scripted set up which is dead simple. Lays down SmartOS and Triton services
  • Compute node install is also scripted which contains a lot of the info you entered during the head node configuration.  After this you run acceptance tests
  • Great support from Joyent with a couple of small issues we had
    • Unacceptable character in pswd. This info was fed back to the devs and is now fixed.
    • We forgot to disable the SATA port and kept getting error messages. Once we disabled it, it worked.

The platform supporting Joyent’s Triton — Dell CTO lab

January 19, 2016

Continuing from the previous post, here is a more detailed explanation of the Joyent Triton platform we set up in the CTO lab.  Triton is Joyent’s elastic container infrastructure that runs on their cloud, a private cloud or both.

The idea behind setting up this instance is, working with Joyent, to learn about the platform.  The next step is to work with the Dell Active System Manager (ASM) team to decompose ASM into microservices and then run it on the Triton platform.

Take a listen as Don walks through the actual layout of the instance.

Some of the ground Don covers

  • Our minimalist set-up featuring two Dell R730 servers (the schematic only shows one for simplicity. An R730 contains two 520s).  Don explains how they are configured and how ZFS affects the set up.
  • The two Dell Force 10 S6000 switches.
  • A double-click on the networking set up
  • The roles the compute and head nodes (the head node acts as the admin into the system).

Intro: Setting up Joyent’s Triton in Dell’s CTO lab

January 18, 2016

A while back I tweeted how we had begun setting up a mini-instance of Joyent’s Triton in our Dell CTO lab.  Triton is Joyent’s elastic container infrastructure that runs on their cloud, a private cloud or both.  This cloud platform includes OS and machine virtualization (e.g. Docker with regards to the former and typical VMs under KVM for the latter).

About a week ago we got the platform set up about and I grabbed sometime with Don Walker of Dell’s enterprise CTO office to tell us about it.

In this first of three videos, Don gives an overview of the work Dell is doing with Joyent.  He describes what we’ve set up in the lab and talks about where we hope to take it.

Some of the ground Don covers

  • Don’s focus on Open Source Cloud eg Open Stack, containers, cloud networking and storage solutions
  • What the enterprise CTO office does
  • What we’re doing with Joyent: evaluating Triton and the process of taking existing products and put them into microservices and containers.
  • Looking at Dell’s ASM (Active System Manager) and what it means to refactor for microservices and containers
  • Overview of what was set up in the lab: a minimalist 2 node instance consisting of head and compute nodes.

Containers, VMs and Joyent’s Triton — how they relate

January 5, 2016

While I was in San Francisco back in November, I stopped by Joyent’s headquarters.  The main purpose was to talk about the Docker/Triton platform we are setting up in the CTO lab.

While I was there I chatted with Joyent’s Casey Bisson, director of product management.  Casey took me through a couple of white board sessions around containers and VMs.  This first session talks about how containers and VMs work together, how they’re different and where Joyent’s elastic container infrastructure, Triton, fits.

Some of the ground Casey covers

  • Linux allows you to build containers on your laptop and push them, as is, to the cloud.  For other OS’s you need to use VMs
  • Containers in the cloud within VMs and the affect on efficiency
  • Running containers on bare metal, security concerns and how Joyent addresses these concerns
  • How Triton virtualizes the network into the container

Learning about Joyent and Triton, the elastic container infrastructure

January 5, 2016

Here’s another interview from KubeCon back in November.  This one’s a twofer.  Joyent’s CEO and CTO, Scott Hammond and Bryan Cantrill respectively, talk about taking their learnings from Solaris zones and applying them to the world of modern apps and containers.

Some of the ground Scott and Bryan cover

  • Joyent, a software company focused on delivering a container native software infrastructure platform
  • They had been doing containers for 6 years and when Docker came along they focused on that
  • How Solaris zones came about, how Joyent picked it up and ran with it, and how it acted as a foundation for today’s containerized world – How they were in the right place at the wrong time
  • Whats in store for Joyent going forward – supporting the movement to modern app dev and the intersection of containers – taking this new tech and productizing and simplifying them to allow enterprises to roll them out

Dell Cloud Marketplace launches public Beta

November 5, 2014

Today at Dell world, we are rolling out the public beta of the Dell Cloud Marketplace.  The marketplace, which is targeted at both sys admins and developers, allows you to set-up, manage, monitor and pay for a variety of cloud services in a self-service model.

The IaaS platforms available at launch are provided by Amazon Web Services, Google Cloud Platform and Joyent.  Cloud services partners include Docker for application development, Pertino for cloud networking and data management provided by Delphix.

Yesterday before the show kicked off I grabbed some time with the marketplace’s chief architect, Campbell McNeill to learn more.  Take a listen to what Campbell had to say:

Some of the ground Campbell covers:

  • What they learned from this summer’s private beta and how they have rearchitected the marketplace accordingly (focusing on control and governance and leveraging the features of the Enstratius acquisition).
  • A market place catalog where you can get apps running in Docker containers and then run them in the cloud of your choice.
  • Providing developers with agility while at the same time giving those tasked with security and compliance a governance control plane.
  • Sign up today and get $500 free credit and give us you thoughts and help us to further refine improve the marketplace.
