we have a large ec2 instance running in asia pacific region.we want to reserve that particular instance.In aws management console we see an option to purchase a reserved instance but there seems to be no option to change this instance into a reserved one.Are we missing out on something Reserved instances are a billing feature, not a technical feature. You can purchase a reserved instance and the discounted hourly rate will apply to already-running instances, without needing to do anything to them. Just make sure the reserved instances you purchase are: - in the same availability zone as your

I need to automatically transcribe some short MP3s as part of a proof of concept I am working on. I am currently looking into cloud solutions or web API services to send the MP3 as a simple HTTP request and receive a transcription back. The only free/open source solution I have found here , but the demos don't seem to work (at least not on the files I need to transcribe). I have found some enterprise solutions for call centers, but so far nothing I can simply integrate into a project. Are there any web based speech recognition services available? One that is able to filter out small noise

Does amazon s3 support batch uploads? I have a job that needs to upload each night ~100K of files that can be up to 1G but is strongly skewed towards small files (90% are less than 100 bytes and 99% are less than 1000 bytes long). Does the s3 API support uploading multiple objects in a single HTTP call? All the objects must be available in S3 as individual objects. I cannot host them anywhere else (FTP, etc) or in another format (Database, EC2 local drive, etc). That is an external requirement that I cannot change. Does the s3 API support uploading multiple objects in a single HTTP call? No,

Here's the thing: I need to take a certain Java EE web app and deploy it to Amazon EC2 (which I will need to setup first) starting next month (using the http://aws.amazon.com/free/faqs/ AWS Free Tier Usage - hope it supports Tomcat + MySQL/PostgreSQL). The problem: I have never ever deployed a Java EE app (not even a normal one on a dedicated hosting) nor have I setup an Amazon EC2 enviorment. Are there any, idiot proof preferably, tutorials/how-to's/whatever on doing it from the very beginning (signing up to Amazon) till the very end (when your app is all up and running)? I did find some

There are a bunch of managed cloud based hosting services for nodejs out there which seem relatively new and some still in Beta. Yet another path to host a nodejs app is setting up a stack on a VPS like Linode. I'm wondering what's the basic difference here between these two kinds of deployment. Which factors should one consider in choosing one over another? Which one is more suitable for production considering how young these services are. To be clear I'm not asking on choosing a provider but to decide whether to host on a managed nodejs specific hosting or on an old fashioned self setup VPS.
