Learn How to Use OpenStack on Oracle Solaris From the Comfort of Your ...

You're probably heard by now that Oracle Solaris provides a complete implementation of the OpenStack platform. Here's a quick view of the integration, courtesy of Glynn Foster:

Horizon Cloud Management Dashboard
OpenStack Component Nova Compute Node Neutron Cloud Networking Cinder/Swift Cloud Storage Glance Image Deployment
Solaris Component Zones and Kernel Zones Elastic Virtual Switch ZFS Filesystem Unified Archives

Glynn has prepared two labs showing you how to get OpenStack running on Oracle Solaris. OTN is making them available virtually, with moderators to help you, in November's Virtual Technology Summit. Because they're virtual, you get to decide whether you want to try them out in the crisp mountain air of your fairytale castle in Germany, the convenience of your Manhattan mansion (who dares to be away from Wall Street for very long these days), or even the regal splendor of Windsor Castle, provided you convince the Queen to let you update her internet.

Lab 1 - How to Deploy OpenStack in 20 Minutes

Use Unified Archives to quickly provision an OpenStack private cloud on a single node and deploy VM instances based on Oracle Solaris Kernel Zones. The basics of cloud administration through the Horizon web interface, and how to quickly provision both Cinder block and Swift object storage using the ZFS file system. Also how the network virtualization features in Oracle Solaris 11 provide the necessary infrastructure to Neutron networking.

Lab 2 - Deploy a Secure Enterprise Private Cloud with OpenStack

Picks up where the first lab left off. Create a golden image environment for an Oracle Database installation using Unified Archives, upload this image to the Glance image repository in OpenStack, and deploy it using Nova compute to a VM instance. How to secure that application in a sandboxed environment using Immutable Zones, and check them for compliance using the integrated framework included in Oracle Solaris 11.

The Virtual Technology Summit is a lot of fun, but you need to register. It's free. It lasts 4 hours. And it's all technology.

We'll also have labs for Oracle Linux and Oracle VM. I'll tell you more about those in an upcoming blog.

About the Photograph

I don't hang with the Queen, so my digs are a little more modest. I took a picture of that cabin on Route 14 on the way down from Cedar Breaks National Monument, in Utah.

Top 10 Articles of 2012 Include Oracle Solaris, Linux, Virtualization

That's a 72 Norton Commando fashioned into a cafe racer. Heavy.com named a newer version the #1 bike in the 2012 New York International Motorcycle Show. (I didn't like Heavy.com's picture, so I found a better one from the blog listed as source, above.)

OTN also has an annual top 10. In that post by Bob Rhubart, from OTN's Architect community, six of the top ten technical articles were about technologies of interest to system admins and developers.

Boo-yah!

#2 - How Dell Migrated from SUSE Linux to Oracle Linux

by Jon Senger, Aik Zu Shyong, and Suzanne Zorn

In June of 2010, Dell made the decision to migrate 1,700 systems from SUSE Linux to Oracle Linux, while leaving the hardware and application layers unchanged. The people who worked on the migration describe how Dell planned and implemented the migration, including key conversion issues and an overview of their transition process.

#4 - Getting Started with Oracle Unbreakable Enterprise Kernel Release 2

by Lenz Grimmer

How to update your Oracle Linux systems to the latest version of the Unbreakable Enterprise Kernel. Switching is easy—applications and the operating system remain unchanged. There is no need to perform a full re-install; only the relevant RPM packages are replaced.

#6 - How to Use Oracle VM VirtualBox Templates

by Yuli Vasiliev

This article explains how to use Oracle VM VirtualBox Templates in Oracle VM VirtualBox. It is similar to the article that explains how to prepare an Oracle VM environment to use Oracle VM Templates, but it describes how to download, install, and configure the templates within Oracle VM VirtualBox, instead of on bare metal.

#7 - How to Update Oracle Solaris 11 Systems From Oracle Support Repositories

by Glynn Foster

You may already know that you don't have to worry about manually tracking and validating patch dependencies when you update a version of Oracle Solaris 11. This makes updates much easier. Glynn Foster demonstrates how easy it is to update the OS from a support repository, and how to make sure everything went well.

#8 - Tips for Hardening an Oracle Linux Server

by Lenz Grimmer and James Morris

General strategies for hardening an Oracle Linux server. Oracle Linux comes "secure by default," but the actions you take when deploying the server can increase or decrease its security. How to minimize active services, lock down network services, and many other tips.

#9 - How to Create a Local Yum Repository for Oracle Linux

by Jared Greenwald

How to create a local yum repository for Oracle Linux, and configure up2date and yum to install and update packages from the repositories.

Basic and Advanced System Services Administration in Oracle Solaris 11

Does taming the behavior of your OS services manually make you feel less than your usual playful self? Lighten up. The Service Management Facility (SMF), introduced in Oracle Solaris 10 and extended in Oracle Solaris 11, provides the discipline those unruly services need. Here are two articles that will help get the most out of it.

Introducing the Basics of the Service Management Facility in Oracle Solaris 11

The SMF keeps track of the relationship between the services in your instance of Solaris. With this information, it can start services much more quickly at boot time, and it restart them automatically in the correct order if any of them fail. And that's only the beginning. In this article Glynn Foster explains what SMF does, and how to perform basic services administration with it, including how to use these four commands to get information about, and manage, your system services:

Command Description
svcadm Manage the state of service instances
svcs Provide information about services, including their status
svcprop Get information about service configuration properties
svccfg Import, export, and modify service configuration

Advanced Administration with the Service Management Facility in Oracle Solaris 11

In this article, Glynn Foster describes how to use some of the more advanced features of SMF, including service bundles, which you can use to deliver custom configuration across systems. And SMF profiles, which modify services to suit a particular installation. The introduction of layers in Oracle Solaris 11 provides better tracking of vendor-supplied customizations and administrative customizations for services and instances of services in four discrete layers, and site profiles, also described in this article, help you manage these layers more easily.
