Most everyone knows that Google has really stepped up to the plate by helping many JavaScript library projects host their builds on the Google AJAX Libraries API. Apart from providing a central distribution point for these libraries, the bandwidth cost savings alone go a long way in helping frameworks service their users in a sustainable manner.
Thanks to Vadim Spivak at Google and Dion Almaer (now at Mozilla) for helping to make this additional option available to the YUI developer community. We love that Google is supporting web developers in this way — grabbing YUI files from Google’s global infrastructure is a fantastic option to have.
This is great news for YUI developers who now have a choice of linking directly to YUI via yui.yahooapis.com and ajax.googleapis.com. YUI team lead, Eric Miraglia, has a great write-up on the YUI blog about this and goes into detail on how the framework’s users can take advantage of this new hosting option.
jQuery and Amazon CloudFront
With nearly 2.5 million requests per day to the jQuery website, the jQuery project team is constantly on the look out for ways to decrease hosting costs while still managing the growing number of requests for the site’s resources. Originally leveraging Amazon S3 for many of their static pages, the project has now turned to Amazon’s new CloudFront CDN. The change has allowed for jQuery pages to be globally hosted as opposed to being centrally located in Amazon’s Seattle-based S3 hosting center.
In tests, John Resig, team lead for the jQuery project, noticed substantial performance gains based on the switch:
I ran a similar test here in Boston and even managed to see a large improvement. I was seeing latency of anywhere from 50-200ms on Amazon S3, but only a latency of 17-19ms with CloudFront.
What does all of this mean? It means that the jQuery site is going to load even faster than it does now. We already receive some excellent hosting from Media Temple but being able to off-load these static files to the fast-loading servers will only make for a better browsing experience.
In less than 24 hours the project had received almost 2.5 million requests for over 50GB of data. The only drawback is an increase in bandwidth costs but still substantially less than that of a traditional hosting plan. The jQuery project makes use of the Google AJAX API as well and recommends it as choice for linking to the jQuery and jQuery UI libraries.
The hosting is free and what makes it unique to something like the Google CDN is that it allows Ext developers a central access point for their own custom builds.
We are pleased to announce that Ext has partnered with CacheFly, a global content network, to provide free CDN hosting for the Ext JS framework. Cachefly’s globally distributed network and aggressive caching accelerate the delivery of web content like JavaScript and CSS, making for an even faster Ext experience.
Dougal Matthews has been playing with Aptana Cloud in a beta form. He wrote up this piece that walks you through the functionality with screenshots:
After creating a project it then is automatically available in the cloud options.
When you click on the project under the cloud menu you are taken through a (very easy to use) wizard for configuration. This runs your through a few steps, setting up a site name, picking a payment plan (the beta is free), payment details and so on. Most of these screens are fairly standard, however the service selection is quite interesting. I imagine these prices are not final, so just take them with a pinch of salt.
The payment scheme seems to be quite flexible and we can see a large number of services that are included, PHP being the main server side language at the moment, with Aptana Jaxer still being a beta… (Ruby of Rails is on the ‘coming soon’ list). The prices range from the cheapest being 256 MB ram and 5 GB hard disc for $0.99 a day, up to 2 GB of ram and 25 GB hard disc for $8.22 a day. Seems fairly reasonably priced.
After set-up is finished, it phones home and does some magic.
This is an important step for Aptana, as it not only gives us a good general cloud service, but it also gives you the perfect place to play with Jaxer. I am looking forward to seeing more.
Aptana Cloud plugs right into your IDE to provide instant deployment, smart synchronization, and seamless migration as you scale. Aptana Cloud is ideal for developers who use scripting languages to create Ajax, Facebook, mySpace and all other sorts of Web applications.
The key is that this isn’t a infrastructure play, which they clearly point out:
Aptana Cloud is architected to complement Cloud infrastructure providers like Amazon, Google, Joyent and others. To get started we’ve selected Joyent who serves up some of the largest of all Facebook apps.
This shows that their platform is designed to go meta, allowing you to deploy to various clouds in the future.
I think that the number one meme from Web 2.0 Expo last week was the “cloud”, coming off of the excitement of Google App Engine. With Aptana Cloud we will see sophisticated tools to make us productive in the cloud. I am very excited to see that it won’t be too long until developers will be able to build an application, hit DEPLOY, and be done. This is a huge win.
For developers:
IDE plug-in integrates Cloud development, deployment and management life-cycles right into Aptana Studio in either its standalone or Eclipse based editions
Instant deployment of projects to Cloud
One click sync your project to the Cloud, or provide fine grained sync control too
Integrated service management consoles
Configure desired memory size and disk size
Develop and instantly preview remote files right inside your Studio desktop environment
Subversion source control.
As Ajax developers, the vision of Jaxer in the cloud is very interesting too. The entire application using JavaScript, and deployed up into the cloud, all through the nice IDE.
I was also pleased to read that not only Ruby on Rails, but Python is on the docket. After developing Django applications and playing with Google App Engine, I would love to be able to use Studio for Python code too. Not that Emacs (X or GNU) isn’t great, Steve!

Other developer features include instant deployment of projects to the cloud; one click can sync your project to the cloud or provide fine-grained sync control; the technology features integrated cloud services management, enables users to provision their cloud right from Aptana Studio, configure desired memory size and disk size, develop and instantly preview remote files right inside the Studio desktop environment, and includes Subversion Source Control.
I have been really looking forward to seeing the Google App Engine launch, and get in the hands of developers. This is just a preview release, and I obviously would like to see more languages and frameworks above and beyond Python and what we have now. The non-Pythonistas will all be saying “what about [insert my language and framework]“. Slowly, slowly, catchy, monkey.
What is the Google App Engine?
Google App Engine lets you run your web applications on Google’s infrastructure. App Engine applications are easy to build, easy to maintain, and easy to scale as your traffic and data storage needs grow. With App Engine, there are no servers to maintain: You just upload your application, and it’s ready to serve your users.
You can serve your app using a free domain name on the appspot.com domain, or use Google Apps to serve it from your own domain. You can share your application with the world, or limit access to members of your organization.
App Engine costs nothing to get started. Sign up for a free account, and you can develop and publish your application for the world to see, at no charge and with no obligation. A free account can use up to 500MB of persistent storage and enough CPU and bandwidth for about 5 million page views a month.
During the preview release of Google App Engine, only free accounts are available. In the near future, you will be able to purchase additional computing resources.
You have to understand the limitations, and the model that is being used. In my mind this is very different than other solutions like EC2/S3. There are very different use cases at work choosing between a low level (and hence very flexible!) provisioning system like EC2, and a deployment solution that gives you a sandbox to deploy applications. Google App Engine is a full stack.
The stack gives you access to Bigtable, which also means that you are not in the world of booting up MySQL. You do things “the Google way” and some people will like it, and some will not. That is fine!
What excites me about this, is that I often have a bunch of little applications that need a host. Sometimes it can be a pain to setup. Other times you would like to make the service public but don’t want people to go hog wild and give you bandwidth costs and contention for your other apps on your host. Now I have a simple place to put these little apps, and this is where Ajax comes in.
As we develop richer applications with more client side logic, and natural service separations, we can create these modules as Google App Engine apps that do one thing well. There will be a natural fit for applications built with GWT, Flex, and other rich component toolkits.
Google App Engine doesn’t give you something that you couldn’t do in an Ajax application, but it does give you a place to throw up these services in short order. This is one step on the way to the world of DEPLOY. There are other services with different tradeoffs, such as Heroku.
I would love to see JavaScript on the server as an option, but that is back to language wars….
