Swift and quotas in upcoming 1.8.0 (Grizzly) release.

There is two new nifty middlewares for doing quotas in upcoming Swift release 1.8.0 called container_quotas and account_quotas. Those are two different middlewares because they are actually addressing different use cases. container_quotas is typically used by end users the use case here is to let user to specify a limit on one of their container. Why would you want to restrict yourself you may ask ? This is because when you allow a public upload to a container for example with tempurl or/and formpost you want to make sure people are not uploading a unlimited amount of datas....

A lot of our customers in Rackspace cloud has been asking how to mass edit firewalls of servers when you have multiple servers without doing it manually.

Howto shutdown your Cloud Server and not getting billed for it.

Currently in Rackspace-Cloud when you are shutting-down your Cloud Servers you are still paying for it. The reason is that when the Cloud Server is shut-down your CloudServer is still sitting on the hyper-visor and still use resources on the Cloud and then get you billed for it. There is a way to get around it by having the CloudServer stored as an image into CloudFiles. The caveat with this solution is that every-time you are creating a server out of the stored image you are getting a new IP and in certain cases you would need to make a change in your application with the new IP....

Uploading to Rackspace Cloud Files via FTP

Sometime ago I wrote a FTP proxy to RackSpace Cloud Files which expose Rackspace Cloud Files as a FTP server acting as a proxy. Thanks to the OpenSource community a user on github took it and add support OpenStack and all the latest features available in Cloud Files. It is now pretty robust and works pretty well via nautilus even with the pseudo hierarchical folder feature. The fun part here is that it allow you to effectively have a Cloud Drive where you can easily store your files/backup from your Linux desktop via nautilus built-in ftp support....

Howto access the UK Rackspace Cloud with the PHP Binding

One of the last library I didn’t documented in my earlier post was php-cloudfiles. You need to have at least the version 1.7.6 released to have support to different auth_server and when you have that you can do it like this to get access to cloud files via the library : <?php require_once("cloudfiles.php"); # Allow override by environment variable $USER = "MY_API_USERNAME"; $API_KEY = "MY_API_KEY"; $auth = new CF_Authentication($USER, $API_KEY, NULL, UK_AUTHURL); $auth->authenticate(); ?...

Backup with duplicity on Rackspace CloudFiles (including UK) script.

It seems that my post about using duplicity to backup your data on Rackspace CloudFiles got popular and people may be interested to use with the newly (Beta) released Rackspace Cloud UK. You would just need to have a environnement exported at the top of your backup script like this : export CLOUDFILES_AUTHURL=https://lon.auth.api.rackspacecloud.com/v1.0 and it will use the UK auth server (the same goes for OpenStack auth server if you have your own Swift install)....
