We are in the process of design a new application which based on a hybrid cloud architecture. We want to keep the data center centralized and managed in-house. And the appserver could be hosted by one of the service providers like EC2 Amazon. I am looking some best practice around data connection between the cloud and datacenter and how ...
I am developing a system that is all about media archiving, searching, uploading, distributing and thus about handling BLOBs. I am currently trying to find out the best way how to handle the BLOB's. I have limited resources for high end servers with a lot of memory and huge disks, but I can access a large array of medium performance off...
I just read tons of material on Amazon's S3 and CouchDB. Maybe not enough yet though, so here is my question: Both systems sound very appealing to me. CouchDB is distributed using the Apache License V2 and with Amazon's S3, you pay per stored megabyte and the traffic you generate. So there is a bit of a difference monetarily. But from...
I'm building some AMIs from one of the basic ones on EC2. One of the instance types is running Tomcat and contains a lot of Lucene indexes; another instance will be running MySQL and have correspondingly large data requirements with it. I'm trying to define the best way to include those in the AMIs that I'm authoring. If I mount /mnt/l...

Anyway, is there any desktop application, that allows me to backup a given folder to a (Cloud) storage service (Amazon / Rackspace / ...) ? Note: I am not looking for companies providing backup solutions, there are plent...
A couple of questions around investing about competency building for Windows Azure. How glorious and revolutionary the platform is. How partners can add value to customers by using Azure. Expanding a little further on my question, there are 2 players in enabling a cloud model for an application The hosting services provider (Micro...
I'm using Amazon's CloudFront to serve static files of my web apps. Is there no way to tell a cloudfront distribution that it needs to refresh it's file or point out a single file that should be refreshed? Amazon recommend that you version your files like logo_1.gif, logo_2.gif and so on as a workaround for this problem but that seem...
What are the challenges in porting your existing applications to Azure? Here are few points I'm already aware about. 1) No Support for Session Affinity (Azure is Stateless) - I'm aware that Azure load balancing doesn't support Session Affinity - hence if the existing web application should be changed if it has session affinity. 2) I...
Is it possible to have multiple worker processes on Azure or do I need to create a separate thread for each to get that behavior? If Azure currently does not support this, are there plans to add this in the future? ...
I've been running some background processes using the Worker role in Azure to test out Azure to see if it something I can consider for one of my projects. When I click on the Analytics tab, I get a message saying "Coming soon.". Is there any way for me to determine some metrics? I'm mostly interested in trying to calculate a potential ...
I have a firefox based application(ff extension) that is supposedly/allegedly working on Mac OSX too. I wish to make the application formally supported in Mac OSX. For that, I need to incorporate automated tests in the build process specific to Mac OSX. With ubiquitous availability of Windows and Linux as cloud offering, executing autom...
Hi everyone, I'm still new to the whole CDN ideaology, so this might be a stupid question but I'm sure someone can shed some light on this. I've got a basic php script that takes user image uploads, resizes them, creates a directory ($user_id), and stores the finished product in the directory (like www.mysite.com/uploads/$user_id/image...
I've spent a long time building stochastic simulations in Java. They work great, but the company hardware is unreliable, getting old and unlikely to be replaced soon. The simulations and number crunching are entirely written in J2SE. Some of them need a little GUI interaction, or to display a window in order to render images which are ...

Eucalyptus is an open source software to create your own private cloud. It uses the same API as Amazon EC2 (and S3 for storage). I heared rumors that Amazon holds patents on the EC2 Webservice API and is therefore able to shutdown Ecualyptus (and other systems using the same API as Rightscale) basically from one day to another. However,...
I have 3 questions related to Amazon CloudFront. How do I upload images? Can I use FTP? Does Amazon allow me to rsynch a local directory to CloudFront so that I have a replica directory and hierarchy on CloudFront? Thanks in advance ...
Hello world. Recently I became very interested in grid computing because I am trying to solve a problem which requires huge, huge amounts of processing power that can be performed in parallel. My question is if there are any grids that are publicly accessible to harness the computing power of thousands of computers? I know only of the W...
Is there a way to display a tag cloud of terms from a single Twitter account within Wordpress i.e. on a page or in the sidebar? I know there's a Delicious Wordpress sidebar tag-cloud - so figured there might be. ...
Hi All, I wanted to know about the difference about cloud computing and distributed computing. I read an article about cloud computing and get an feeling that somewhere there is relation between cloud computing and distributed computing and so wanted to ask about difference between technologies.

When you use the Table Services API in Windows Azure what is really doing under the hood? I think I read somewhere that this is not using SQL Server. Is it doing a hash table and then filters are really running like map/reduce actions? I'm really new to this stuff and I'm curious to what it is really doing. ...
