Introduction: You may have noticed something is a little a different when visiting HighScalability today: We've Moved! HighScalability.com has switched hosting services to Squarespace.com. House warming gifts are completely unnecessary. Thanks for the thought though. It's been a long long long process. Importing a largish Drupal site to Wordpress and then into Squarespace is a bit like dental work without the happy juice, but the results are worth it. While the site is missing a few features I think it looks nicer, feels faster, and I'm betting it will be more scalable and more reliable. All good things. I'll explain more about the move later in this post, but there's some admistrivia that needs to be handled to make the move complete: If you have a user account and have posted on HighScalability before then you have a user account, but since I don't know your passwords I had to make new passwords up for you.

2 While the site is missing a few features I think it looks nicer, feels faster, and I'm betting it will be more scalable and more reliable. [sent-9, score-0.283]
3 Sorry for this hassle, but for posts to be assigned to authors on import user accounts had to exist so I had to create them. [sent-14, score-0.678]
4 If you have a user account and have never posted on HighScalability before you'll have to register in order to recreate your user account. [sent-19, score-0.412]
5 Sorry, but with so many users I couldn't recreate all the user accounts by hand. [sent-20, score-0.313]
6 I want it to be managed end-to-end by the hosting service. [sent-40, score-0.272]
7 In industry when they say they offer a managed service they usually mean the hardware/network/software stack are managed, you are still responsible for site uptime. [sent-41, score-0.376]
8 By leaving the management of the entire stack to the hosting service then this worry largely goes away, assuming the host is good at their job. [sent-47, score-0.208]
9 A managed VPS with any sort of capability is expensive for a site that doesn't generate a lot of revenue yet gets too many users for shared hosting. [sent-53, score-0.519]
10 A price point between shared hosting and a managed VPS would be very attractive. [sent-54, score-0.272]
11 Some of the end-to-end managed services are enterprise plays and are way too expensive for the little guy. [sent-55, score-0.293]
12 A site is managed through a truly innovative browser based GUI that makes template customization and other operations quite straightforward. [sent-64, score-0.321]
13 It will also tell you cool things like how many RSS readers you have and which posts are getting the most traffic. [sent-65, score-0.222]
14 So simple widgets like avatars, tag clouds, today's popular posts, the most popular posts of all time, recent forum posts, read counts, and logged in users are not available. [sent-85, score-0.472]
15 Drupal is not one of Squarespace's supported import platforms. [sent-87, score-0.238]
16 Squarespace does not have their own defined import format, which would have made life a lot easier. [sent-91, score-0.305]
17 Some other problems is there's no way to bulk operations to import users and map URLs. [sent-92, score-0.491]
18 If you don't have the users already created when posts are imported then the posts won't be assigned to the correct author. [sent-94, score-0.648]
19 Squarespace does have a way to map URLs, but again there's no way to bulk import the mappings. [sent-97, score-0.472]
20 These issues weren't serious enough for me not to go with Squarespace, but a site looking to build a real community may have to look a little closer. [sent-101, score-0.207]

Introduction: I first heard an enthusiastic endorsement of Squarespace streaming from the ubiquitous Leo Laporte on one of his many Twit Live shows. Squarespace as a fully hosted, completely managed environment for creating and maintaining a website, blog or portfolio was of interest to me because they promise scalability and this site doesn't have enough of that. But sadly, since they don't offer a link preserving Drupal import our relationship was not meant to be. When a fine reader of High Scalability, Brian Egge, (and all my readers are thrifty, brave, and strong) asked me how Squarespace scaled I said I didn't know, but I would try and find out. I emailed Squarespace a few questions and founder Anthony Casalena and Director of Technical Operations Rolando Berrios were kind enough to reply in some detail. The questions were both from Brian and myself. Answers can be found below. Two things struck me most about Squarespace's approach: They based their system on a memory grid, in this

Introduction: There was a bit of drama earlier when I posted a free job opening for Zynga. It caused unfortunate and just plain wrong accusations. It also caused a number of requests for more free job posts, which I should have anticipated, but obviously I can't let this blog become cluttered with that kind of stuff. Earlier I tried a job board type service, but that never really worked out. So what to do? Someone suggested a sponsored post approach and I think that's a good compromise. It minimizes the noise, let's people know about work, and brings in a little revenue. It works like an advertisement. If you are interested please let me know. When we have any job openings there will be a sponsored post like this one, that you can easily ignore or pay attention to, depending on your situation.

2 0.80266786 724 high scalability-2009-10-19-Drupal's Scalability Makeover - You give up some control and you get back scalability
Introduction: Drupal 7 is having a scalability makeover. Karoly Negyesi, Drupal Core Developer and Public Development Team Lead, explains the process in this video: Drupal 7 APIs, scalability mindset . Karoly states the general theme of the changes as: You give up some control and you get back scalability . An interesting comment on the politics of scalability? Makeover may not be quite the right word though. A makeover implies a cosmetic change, looking better by changing the surface. Drupal's changes will go deeper than that, right to Drupal's core. It's a genuine and authentic change that will hopefully allow one of the Internet's most venerable Content Management Systems (CMSs) to compete with a constant stream of younger and sexier models. Drupal is based on an older LAMP stack approach where PHP modules are scooped up and merged together each time a request is made to Drupal. Drupal's most intriguing idea is how it is built, expands, and changes by weaving together a single system out

An interesting point was that errors that could harm a site's reputation started at 1000 users. Cheers to the company that had the guts to give this a try. That which doesn't kill your site makes it stronger.

Of course I'm not suggesting that you run your site into the ground, but better to know what your real (not simulated) loads are while you're watching, than find out the hard way.

Introduction: A lot of sites hosted in San Francisco are down because of at least 6 back-to-back power outages power outages. More details at laughingsquid . Sites like SecondLife, Craigstlist, Technorati, Yelp and all Six Apart properties, TypePad, LiveJournal and Vox are all down. The cause was an underground explosion in a transformer vault under a manhole at 560 Mission Street. Flames shot 6 feet out from the manhole cover. Over PG&E; 30,000 customers are without power. What's perplexing is the UPS backup and diesel generators didn't kick in to bring the datacenter back on line. I've never toured that datacenter, but they usually have massive backup systems. It's probably one of those multiple simultaneous failure situations that you hope never happen in real life, but too often do. Or maybe the infrastructure wasn't rolled out completely. Update: the cause was a cascade of failures in a tightly couples system that could never happen :-) Details at Failure Happens: A summary of the power
Introduction: Here's a common situation and question from the mechanical-sympathy Google group by Avinash Agrawal on the black art of capacity planning: How to get started with sizing and capacity planning, assuming we don't know the software behavior and its completely new product to deal with? Gil Tene , Vice President of Technology and CTO & Co-Founder, wrote a very understandable and useful answer that is worth highlighting: Start with requirements. I see way too many "capacity planning" exercises that go off spending weeks measuring some irrelevant metrics about a system (like how many widgets per hour can this thing do) without knowing what they actually need it to do. There are two key sets of metrics to state here: the "how much" set and the "how bad" set: In the "How Much" part, you need to establish, based on expected business needs, Numbers for things (like connections, users, streams, transactions or messages per second) that you expect to interact with at the peak t

Introduction: Matthew Might , as a first responder to a surprise traffic surge on his inexpensive linode hosted blog, took emergency steps that you might find useful in a similar situation: Find the bottleneck. Reloading the page in firebug showed the first page took 24 seconds to load and after that everything else loaded quickly. In retrospect this burst meant the site was thread limited as the CPU was idle. Cut image sizes in half with a shell script using ImageMagick's convert. Load time is now 12 seconds. Turn dynamic content into static content using a static index.html file copied using the browser's "view source" feature. Load time is now 6 seconds. Added threads to the Apache configuration file. Load time is now 2 seconds. Crises averted. Because of this quick thinking and quick action the patient survived to serve pages another day. And in fine post-mortem tradition some of the future changes are: Run a cron job to trigger an earlier alert . Email when requ

Introduction: Sify.com is one of the leading portals in India. Samachar.com is owned by the same company and is one of the top content aggregation sites in India, primarily targeting Non-resident Indians from around the world. Ramki Subramanian, an Architect at Sify, has been generous enough to describe the common back-end for both these sites. One of the most notable aspects of their architecture is that Sify does not use a traditional database. They query Solr and then retrieve records from a distributed file system. Over the years many people have argued for file systems over databases. Filesystems can work for key-value lookups, but they don't work for queries, using Solr is a good way around that problem. Another interesting aspect of their system is the use of Drools for intelligent cache invalidation. As we have more and more data duplicated in multiple specialized services, the problem of how to keep them synchronized is a difficult one. A rules engine is a clever approach. Platfo
