Leveraging a disaster recovery site for development - Part 2

In our previous post, we introduced the idea of using Disaster Recovery (DR) sites as a private cloud for hosting virtual development and testing environments. The solution we developped for an ISV partner of ours in the Healthcare sector looks like this.

Architecture

The solution is based on the Zones and ZFS features of Oracle Solaris --available from Solaris 10 and up. Solaris Zones (a.k.a. Containers) are an operating system level virtualization technology that…

Leveraging a disaster recovery site for development - Part 1

As part of the software development lifecycle, the application testing environments are often overlooked and mostly left to the appreciation of each developer, who routinely end up using their own PC or laptop for that. The main advantage here is that it gives developers full control on the testing environment without interfering with other developers or worse, with the production system.

There are however some serious drawbacks with this method:

  • Installing and configuring the various layers of software is time consuming and unproductive. Not to mention that developers (rightfully) test a lot by messing around with their environment or data, so the burden of installing and configuring is a repeating one.
  • Developers are unable to leverage and test the scalability of their code on the hundreds of threads that modern production servers offer.
  • Copying hundreds of gigabytes from the production database to every laptop is not an option, leaving the developers test their code on small, often outdated, data sets.

With the advent of virtualization, using ready-to-boot virtual images of a fully pre-installed and configured application testing environment on an internal cloud has become…[Read More]

Why Solaris Zones?

Our recent validation exercise of SAP NetWeaver Master Data Management on Oracle Solaris Containers reminded us how great a virtualization technology Solaris Zones are. Why am I saying this? Read on.

Starting with Solaris 10, Solaris Zones (a.k.a. Containers) are an operating system level virtualization technology that provides a complete, light-weight and secure run-time environment for applications. Compared to other virtualization solutions, Zones do not use an hypervisor --which in fact is another layer of operating system that translates / gets in the way of your system calls to the hardware--, rather Zones are an integral part of a running Solaris instance. Still, Zones meet the same business objective of server consolidation thru Virtual Machines (VM), isolated from each other and designed to provide fine-grained control over the hardware resources.

The following benefits are often put forward about Solaris Zones…

Planet Work offers bargain hosting on Solaris Zones, ZFS

Adapted from this (French) Sun Startup Essentials blog piece.

Planet Work is a Paris-based web hoster that has been operating for about 10 years now. For some time, they had been looking at virtualization technologies with the goal of offering a very competitive --low price, high availability-- entry-point hosting solution. As a member of the Sun Startup Essentials program, Planet Work worked over the past year with a local engineer in our team to evaluate what Solaris had to offer in the virtualization space. They were not disappointed.

Read on to learn how Planet Work could deploy a new iServer Solaris offering, targeted at startup developers, with a low entry-price of 19€ per month, automated ZFS-based backup service and a low cost of operation.
