In a comment on my post about Slicehost, Linode, and scaling up servers  it was suggested that there is no real difference between a physical server and a set of slices of a virtual server that takes up all the resources of the machine.
The commentator notes that it’s easier to manage a virtual […]
Last week I gave a talk for the Linux Users of Victoria about Cloud Computing and Amazon EC2 . I was a little nervous as I was still frantically typing the notes a matter of minutes before my talk was due to start (which isn’t ideal). But it went well. There were many good questions […]
One of the exciting things about having a cloud computing service is how to talk to the rest of the world. It’s all very well to have a varying number of machines in various locations, but you need constant DNS names at least (and sometimes constant IP addresses) to do most useful things.
I have […]
I have previously written about my work packaging the tools to manage Amazon EC2 .
First you need to login and create a certificate (you can upload your own certificate – but this is probably only beneficial if you have two EC2 accounts and want to use the same certificate for both). Download the X509 […]
The term Cloud Computing seems to be poorly defined at the moment, as an example the Wikipedia page about it is rather incoherent .
The one area in which all definitions of the term agree is that a service is provided by a varying number of servers of which the details are unknown to the […]
I have access to a server in Germany that was running Debian/Etch i386 but needed to be running Xen with the AMD64 version of Debian/Lenny (well it didn’t really need to be Lenny but we might as well get two upgrades done at the same time). Most people would probably do a complete reinstall, but […]
Last time I tried using a Debian 64bit Xen kernel for Dom0 I was unable to get it to work correctly, it continually gave kernel panics when doing any serious disk IO. I’ve just tried to reproduce that problem on a test machine with a single SATA disk and it seems to be working correctly […]
I’ve updated my package of the Amazon EC2 API Tools for Debian . Now it uses the Sun JDK. Kaffe doesn’t work due to not supporting annotations, I haven’t filed a bug because Kaffe is known to be incomplete.
OpenJDK doesn’t work – apparently because it doesn’t include trusted root certificates (see Debian bug #501643) […]
The first thing you need to do to get started using the Amazon Elastic Compute Cloud (EC2)  is to install the tools to manage the service. The service is run in a client-server manner. You install the client software on your PC to manage the EC2 services that you use.
There are the AMI […]
One of the most interesting new technologies that has come out recently is Cloud Computing, the most popular instance seems to be the Amazon EC2 (Elastic Cloud Computing). I think it would be good if there were some open alternatives to EC2.
Amazon charges $0.10 per compute hour for a virtual machine that has one […]
