Recent Acquia Hosting Updates

The hosting team at Acquia has been busy! While we continue to focus on making Acquia Hosting the most reliable and scalable Drupal hosting service anywhere, we've recently made significant enhancements to its usability and to the data we provide our customers.
First up are several improvements to our Acquia Hosting UI. We've added a new tab to show statistics at several points in the hosting stack including before and after the front end cache and well as a count of total Drupal requests. For more detail, please read Kurt Gray's excellent blog post.
We've simplified the server architecture information in the UI to clearly show the load balancers, web servers, and DB servers assigned to your site. We show server name, role, Amazon instance type, and a links to your log files. Over time, we'll continue to extend this display so you have easy access to the information you need to manage your site and understand how it's performing.
Other recent changes include:
- Cache clearing: Customers can now clear their front-end Varnish cache themselves via a link on the hosting tab. You can clear the entire cache or one hostname at a time.
- ah-import-db: An optimizing DB import tool.
- Drupal performance checker: We've taken Acquia's Drupal performance tuning expertise and written a script that identifies common Drupal configuration mistakes. Right now, our support team uses the script to check a site prior to it going live. Over time, we'll continue to extend this with an eye towards making it smarter and usable directly by customers.
- Performance improvements: With nearly every release (typically one a week), we implement better Drupal stack tunings. Last week, we tweaked our APC bytecode cache configuration to significantly reduce disk I/O for high traffic sties.
Stay tuned for more. And please let us know what Acquia Hosting improvements you'd like to see.

I just found a cool service that identifies the hosting provider for any particular web site: www.WhoIsHostingThis.com. Although there are a few similar services out there, WhoIsHostingThis digs a little deeper to find the actual provider even if they're built on another cloud provider's infrastructure.
Check it out using some of the Acquia Hosted websites:

Drupal Commons, Acquia’s new Social Business Software distribution of Drupal, is no doubt getting everyone excited. We’re especially seeing interest in the enterprise and public sector. The community solution is important because its an open source alternative to (social business software products like) Jive and another way to accelerate adoption of Drupal in the marketplace. Drupal Commons evolved because of countless inquiries and interest from organizations who want to use Drupal to build community sites. Not surprisingly, many other Drupal distributions evolved for the same reasons.

Barry and I just met with a team from Northscale -- the startup formed to support and extend Memcached, the popular key-value cache used by the largest web sites. We learned about their new database project, Membase, and talked about how it could help high-volume Drupal sites including our Acquia Hosting customers.
Membase is built on the core Memcached technology and supports the Memcached API. I'm excited about what they've done to extend Memcached:

2010 has been an inflection point for the Acquia partner program. We are doing more business than ever with partners, including case studies with Palantir.net, Blink Reaction, and IBM Global Services.

It is that phase of my life! I'm just turning 30 in a month, working with Drupal for 7 years and just had my third Acquia anniversary a week ago. Time to look back and evaluate how things went, all the good and bad things; even better if the wisdom can be shared with others. This was part of my thinking when I submitted the session titled "Come for the software, stay for the community" for Drupalcon Copenhagen.

It sounded like a really simple request: "Is it easy to add a search filter for 'My posts'?". In other words, add a search result facet for posts by the current (logged in) user through the Apache Solr Search Integration module APIs?
But then the wheels start turning - we want not just one blind link, but a real facet link that tells us how many results we'll get. Also, if we are filtering by 'My posts' then we probably have an equal use case for the opposite filter 'Posts not by me'. So we really need a facet block with two links and facets counts.

The biggest request in my
The biggest request in my mind is an object cache like Memcache. It's the one major thing missing from the stack in terms of performance. Right now the Acquia stack is best for sites that have anonymous visitors (i.e. Pressflow/Varnish) but not as tuned for logged in users. Certainly APC and the database architecture is helpful, but memcache would greatly extend the ability to provide a high-performance experience for authenticated users.

I partially disagree with
I partially disagree with this. We have several customers performing well with very large numbers of registered users. For example, I know one that has at least 300K registered users. Note that in D5 and D6, the Pressflow extensions (or similar improvements to the default user queries) are required to get reasonable performance with 100K+ users.
While a custom-integrated memcache server could result in significant speedups, most of our customers are not willing to undertake that level of development effort. We don't currently see dramatic improvements by just using the standard Drupal memcache module since it caches relatively little data.
I'd love to see more data from real sites on the benefits of memcache and particular with sites only using the default memcache module.
That said, we do think memcache offers significant benefits for customers willing to make the effort to use memcache to its full potential. For that reason, you'll see us (probably) announce memcache support later this quarter.
