I was wondering if anybody out there is doing their software builds using something like Amazon's EC2. I was thinking about trying to move our builds into that environment. Right now our builds are serial but only because we don't have enough computers to run all the components in parallel. Using EC2 we could create 50 or so computers...
I'm interested in running CPU-intensive computations in clouds. The only real requirement is ability to run .NET applications (F# algorythms like this one) with enough security permissions for using reflection-based IoC Container. Persistence technology does not really matter as long as something is there. I'd like to know of your exper...
I'm looking to manage a system (or preferably multiple systems) of machines on EC2, and at present the only way I can see doing that in a reasonable way is to extend the Typica library and build a control panel that launches, configures, and checks in on machines for me. I don't expect there to be any prefabricated solutions to exactly ...
What AMI images do you use when deploying or testing .NET applications at Amazon EC2? Is this image based on Windows or Linux? Is it an image from AMI repository or something that you've built (if so, then is it public)? What version of .NET does it support (applies for Linux)? What other important features does it include? So far I'...
This is a weird one that anyone can repro at home (I think) - I am trying to write a simple service to run searches on Twitter on a service hosted on EC2. Twitter returns me errors 100% of the time when run in ruby, but not in other languages, which would indicate it's not an IP-blocking issue. Here is an example: admin@ec2-xx-101-152-x...
I'm going to deploy my application on one of them, and have no idea which is better. ...
I would like to test a trivial SOAP app against Microsoft Exchange 2007 (or 2010) webservices. Is there any demo server on the internet available? My problem is, that I have no 64-Bit machine around here to install a server for myself. The 2003 server, which is hanging around at the office isn't suitable for my needs (Exchange Web Servi...
This question is for anyone who has actually used Amazon EC2. I'm looking into what it would take to deploy a server there. It looks like I can start in VirtualBox, setup my server and then export the image using the provided ec2-tools. What gets tricky is if I actually want to make configuration changes to my running server, they will...
I have a software that is pretty complex in the sense that it uses a lot of interacting processes, os daemons, services, etc. So I think the most sensible way of distributing it would be as a virtual machine image, otherwise the installation in an arbitrary machine would be too complex. What are the pros and cons of such a model? What...
I'm trying to get emacs tramp running under Windows XP to work over putty plink on an Amazon EC2 instance. The documentation for doing this is sparse. I can find partial documentation, but none that addresses all the steps required to get this working. Can anyone provide a walk through, or a pointer to a walk through? ...
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...
Hi, I was curious if anyone has experimented with auto-scaling web or db tier in ec2 or other cloud computing infrastructure? It seems theoretically possible but I am curious what the practical limitations are/maybe. Thanks, manish ...
Assume I have huge huge data and no money for hardware for more RAM for R AND software like Windows or any non open source . Just an internet connection. and an university Amazon ec2 account. Could you please guide me to a step by step- copy and paste coding tutorial on building a model using any Package on Amazon ec2. Note- I know BI...
I am having a problem with encoding the hash for the Version 2 Signature of the ec2 API. Note my Version 1 Signature hashing works fine, but this is depreciated and I will need to move to version 2. So firstly here is the code that works... parameters is just a dictionary, what I have to do is simply sort the parameters by key and appe...
Hi All, Do you know any great book about Amazon Web Services and how to exploit it the best way to do load balancing? Many thanks for any help, Best, Raphael ...
I am looking for a way to dynamically stream download a zip of files from Amazon S3. The application is hosted on EC2 and the files are stored on S3. Need to give users the ability to select from a group of files which will then get bundled up and downloaded to them. Have heard about a few Actionscript libraries (aszip and fzip) tha...
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...
Is it possible to write map/reduce jobs for Amazon Elastic MapReduce (http://aws.amazon.com/elasticmapreduce/) using .NET languages? In particular I would like to use C#. Preliminary research suggests not. The above URL's marketing text suggests you have a "choice of Java, Ruby, Perl, Python, PHP, R, or C++", without mentioning .NET lan...
We have been requested to stream a single video (+500MB) from a web site. The biggest additional requirement is that access must be forbidden to foreign IP addresses. Given that high bandwith usage is expected we have turned to Amazon S3 to serve the video as a FLV, but AFAIK Amazon won't let you set up IP filtering based on country l...
Hi, I have several newbie questions about EC2, thanks for your attention, 1) why EC2 instances come with specific memory/storage quotas? In the cloud environment, can't we just request the amount of memory/storage as we require, and the amazon infrastructure take care of the allocation? I understand an pre-determined allocation of mem...
