Mercury

This is pretty exciting Amazon has announced a Micro Instance for only $0.02 an hour with 613mb RAM and up to 2 EC2 Compute Units. I know a lot of people were using other cloud computing providers due to the lower price point so this potentially opens Amazon up to a much larger market.

Only problem is I just tried to launch a Pantheon instance on it and realised the new instance size requires an EBS Bootable instance.

I'm seeing a behavior where varnished pages stay cached for only 10 minutes. Examining my headers, I guess I'm confused about what I should be seeing. Below is an example of the response & request headers for a Pantheon page served up to an anonymous user.

Cache-Control:public, max-age=600
Is this the culprit? Does this seem too short? The varnished page "Age" will go up to 600 and then reset to 0. Before reset the page loads quickly on different browsers, but when it resets, it needs to load the whole page again. Something doesn't seem right there.

Hi all, I'm sure there must have been some tests run on Pantheon, but I can't find any documentation of such anywhere.

Specifically I'm interested to learn how many logged in users (doing regular stuff like browse the site, post a question, look at a profile etc) could pantheon running on an EC2 server created from the AMI handle?

At what level of logged in users might we expect Pantheon to start having trouble?

Anyone know how to find the cookie names that can be used in a varnish vcl? My varnish isn't caching anything, i suspect cookies from adsense/fb scripts... been using mozilla's 'live http headers' and firebug but no combinations or patterns of cookie names i use seem to work!

Congratulations! If you're reading this, you're doing things correctly. In the modern era of the web, we don't want to be making edits directly on a live site. It's just too risky, and it starts getting really tricky when you're working with a team. Deploying from version control solves these problems.

If you already have your own system or method of deploying a whole Drupal installation, feel free to take over all of /var/www on your PANTHEON server. You should base your application on Pressflow and include the ApacheSolr, Varnish and Memcached modules as well as the necessary settings.php configuration to utilize these features. For more on this, see the settings and module configuration page.

However, if you don't have an existing deployment system, but you do keep your code in version control (e.g. SVN) you can easily integrate with the provided Pressflow installation — which is itself checked out from Launchpad for easy updating — by following these instructions:

I am planning to use Mercury for a new architecture installation on Rackspace Cloud. We are planning to move an existing site over. I reviewed the instructions at http://groups.drupal.org/node/70268 but wanted some feedback on how others are planning their database. Is everything running on 1 large server, Apache, Mercury, MySQL, etc or is it better to run a separate database with a 2 server configuration. The site get's about 125,000 page views per month so it's still rather small.

Thank you

Hello all,

First thank you for all the work that has been put into Aegir and Mercury/Pantheon. I've been keeping an eye on both for a while and am ready to jump in. While my needs aren't heavy ... yet. A current project has the potential to need the power and scalability of Mercury/Pantheon and I want Aegir to make life simpler for implementing new sites and creating test development environments. So with that in mind I am creating a new server at Linode and will be migrating my sites(mostly D6 with one D5) from my old standard server.

Since I am converting from a box that wasn't using Apache/Solr, had no reverse proxy(Varnish) or caching such as APC/memcached in place I don't have to have those options fully in place on day one. I can activate those as I get a handle on their unique twists due to multi-site on Mercury/Pantheon. But I do want to lay the groundwork and get as much in place up front as I can.

I have been reading everything I can find(I'll include some of the links at the end of this post), which has answered many of my questions. But has also lead to a few more detailed new ones.

Thanks to the developers of these capabilities for all the wonderful work they've been doing.

As someone who is currently experimenting with Pantheon/Mercury, and who also has an interest in Aegir, I wonder whether the rumor I read about a forthcoming version of P/M with Aegir integrated is true. That would be great, of course, and may affect how I approach my current efforts.

Background: The Drupal 6 site used to work very well on a VPS until a few months ago. However in order to reduce the server cost as well as to improve performance of the site even more, we decided to move to the cloud and Pantheon. We setup a pantheon server and moved a copy of the site on rackspacecloud and tested it using Jmeter with 1000 users and tested continuously for 4 hours and the load never went more than 1. The Jmeter report showed only .4% error(which was normal i think).
