This post discusses why cloud identity is such a difficult problem to resolve.
After a short hiatus I’m finally blogging again.
Some might think that I needed to recover from England’s unimaginative showing at the Euro’s and their inevitable exit on penalties in the quarter finals.
This is not true, I’ve been a busy working.
One of the things I’ve done is to get more familiar with the available open source cloud offerings, in particular looking at OpenStack, Eucalyptus and CloudStack.
I used Martin Loschwitz’s excellent instructions here for the installation of OpenStack on a Lenovo T5010 laptop running Ubuntu 12.04 Precise Pangolin.
A couple of things to note:
- Hardware virtualization must be turned on at the BIOS level otherwise the VM fails to start with spawning errors.
- There is only one NIC on this laptop so I created a virtual adapter for the second NIC.
- Don’t forget to create the LVM volume group called nova-volumes. This is mentioned at the end of step 1 but no instructions are given. For those who need them:
dd if=/dev/zero of=MY_FILE_PATH bs=100M count=10
losetup –show -f MY_FILE_PATH
apt-get install lvm2
vgcreate nova-volumes /dev/loop0
I also installed OpenStack on an ESXi virtual machine. There are lots of instructions for installing it on VirtualBox but very little for installing it on VMWare. The issue is the requirement for hardware virtualization support.
It seems that there may be a way around this with VMWare’s vSphere 5 but I didn’t want to start reconfiguring the company ESXi server so I created a Ubuntu 12.04 virtual machine and installed DevStack by following Sam Johnston’s instructions here. This is a documented shell script to build a complete OpenStack development environments from RackSpace Cloud Builders that installed in less that fifteen minutes.
I shall now get familiar with the APIs and try to determine how easy it is to integrate with Open Source provisioning software.
A plan to create a standard protocol to ease provisioning of corporate users to cloud services should be approved as an IETF working group early next month.
