I am choosing a platform for a web application. I understand how cloud computing can scale front end servers, but what do they do with the database servers? Is there something that the developer has to do to allow for this? ...
What would be a good way to attempt to load the hosted jQuery at Google (or other Google hosted libs), but load my copy of jQuery if the Google attempt fails? I'm not saying Google is flaky. There are cases where the Google copy is blocked (apparently in Iran, for instance). Would I set up a timer and check for the jQuery object? What...
I am building a .NET MVC web application. Is cloud hosting the way to go for a 1 man show? Since StackOverflow runs off a simple 2-node setup, and can easily be doing 1 million page views/day, does cloud hosting even make sense until one gets to that level? Do you think cloud hosting will really take away the server hosting side of thi...
Is that kind of information available for public? ...
The main bottle neck of a web server locates usually in the database,in my case,MYSQL. More specifically,fulltext search and master-slave replication. And sphinx is a probable solution for fulltext-search,so master-slave replication is the final pain in ass. Is it possible to boost the performance significantly with the technology o...
Virtualization & Cloud Computing. I know these are very vague, nebulous words that mean so many different things. They are also the topics that are most discussed today. However, because they are so new, they are not taught in schools. I was lucky to have couple lectures on virtualization technology and read a paper about it. I now want...
I'm working on a Silverlight app that would allow a user to upload a few gigs of files to a hypothetical cloud based file store, then allow the user to view some data about those files later (more functionality than a file store). Ideally I'd like to use a free, per-user store such as SkyDrive but I can't seem to find an API for that se...
I was wondering if anyone knows of any good Open Source distributed computing projects? I have a computationally intensive program that could benefit from distributed computing (a la SETI@Home, etc.) and want to know if anyone has seen such a thing or will I be developing it from scratch? ...
Hi, What are the significant differences between Cloud Computing and Grid Computing ? What are the precise definations and target application domains for both ? I'm looking for conceptual insights along with technicalities. Like Windows Azure is a Cloud OS, do we have anytihng such for Grid Computing ? In past I did work on distribute...
I was wondering if there was any way in PHP to pass an external download off to a user? What I would like to do with the script is depending on certain conditions, send the user a file from server A or server B. However, I don't want the user to know the direct url to either server. Ex: User visits (which is on server C): http://example...
Hi there, is there any way to update files stored on Amazon's CDN service? Seems like it won't take any update of a file we make (eg. removing the file and storing the new one with the same file name as before). Do I have to explicitly trigger an update process to remove the files from the edge servers to get the new file contents publi...
While computer programming evangelists predicting the future of Cloud Computing to be very bright, is there a chance for relational databases to be on their way out? What are the DBs that are more suitable for Cloud Computing? ...
In the systems-admin sector, servers and IT infrastructure is being moved into datacenters and IT staff are sometimes cut. Is it possible for the same thing to happen to software developers, that the world's software could be produced by a few massive corporations instead of by so many developers? ...
Salesforce’s secret sauce: It queries its databases with “The Multi-Tenant Optimizer" So exactly what could this practice be comprised of? ...
I'm trying to come up with some data on how many much computing power the current cloud platforms represent. (Microsoft Azure, Amazon Elastic Compute Cloud, Google App Engine. Others?) Stuff like how many physical/virtual machines, storage space. How many datacentres are the big players setting up/running already. Any metrics would be f...
I am looking for help with the database scheme, not the actual "cloud" itself. In a site where users submit images and can tag images, how should the database be setup for optimal performance? I was thinking ID - int(11), unique, auto_incremenet tag - varchar(20) imageID - int(11) so suppose i upload an image, and tag it "toronto, s...
Any one one know of the best practices to be followed when implementing an application in the cloud? I would like to build an application, which is cloud independent. So, a DAC should be able to work against S3 / AppEngine / Azure just by changing a configuration. Is there any framework or best pattern to be followed so that code is Clo...
Google App Engine is a cloud computing architecture that supports java based web services to be deployed. What cloud computing hosting options are available for .Net web developers ? ...
I would like to render volumetric clouds in OpenGL. I found an interesting paper that describes a simple technique to render volumetric clouds. (http://www.inframez.com/events_volclouds_slide18.htm) However I don't know how to create their "fractal cube" (or perlin-noise cube). My question is: how to create the 6 tileable fractal textur...
I'm wondering if anyone here has tried using Esper to process stuff from the Cloud? Specifically Amazon's Simple Queueing Service. I've googled about this, and we know it's feasible, but it would be nice to know if anyone has tried it. Even better has anyone tried putting Esper into the cloud as well? ...
