I've been using Amazon RDS for a while now, and supplementing the automated backups with my own mysqldump backup routine that copies the sql dump to a remote (not AWS) server.
The mysqldump causes server load to spike, though, and is generally a resource hog. I'd like to get rid of it if I can.
The native RDS automated backup routine seems pretty robust and reliable, as far as I can tell. Is my (less-efficient, more management-intensive) redundant routine necessary, or am I just being paranoid?
FWIW, the data is mission critical, in the sense that losing all (or most) of it would be catastrophic to the organization. However, losing a small amount of data (e.g., 5-10 minutes worth), would not be too terrible.
Thanks.

I wrote my first web app using Sinatra. It's pretty simple with a REST interface. I am running MySQL database and it connects to it using active record, very cool stuff. Also, I am running another ruby program which basically queries the MySQL database every 30 seconds and does some work on the data and updates the db.
Right now, I am running sinatra app on my laptop. I want to move this to a server because i can't keep my laptop on all the time.
I checked out Amazon EC2 and there's so many options that I am over whelmed. Is Amazon EC2 even a good choice? Is so, what option is best for me? I am not expecting any bandwidth.
Any pointers for someone starting with webservers/hosting would be great, Thanks!
Well there's a free micro instance for new customers so that seems like the logical place to start. If it's not enough you can consider upgrading, look at the reserved/on demand pricing and make an informed decision at that point.
Have you looked at hosting with companies such as Heroku and AppFog?
They both offer free plans so you can give them a go before upgrading, or you may find the free plan is enough.

I need to set up an amazon server. I always here "setup ubuntu on amazon ec2" which sounds simple enough in theory, but what are all these other things!
The main question is "sure I can google ec2 setup, but are these other web services offerings any better suited for me than ec2"
there are so many that it is a bit overwhelming. I need to run a server that I can code on and process data with, is an ec2 instance what I need or is it something else? if this is too vague then at least paste some resources here to point me in the right direction
thank you for any insight
You need EC2 - just go to the EC2 Getting Started guide in the AWS documentation and it will walk you through what you need to do.

for data storage which is the better storage system.from the development
sql to Linq,
isolated storage,
application page etc.
isolatedstorage has certain drawbacks as it cannot persist dictionary etc.
please help
Depends on your need:
Isolated Storage is for persistence of non-relational data. Yes, it can persist dictionaries.
SQL CE is for use when you need to persist truely relational data.
PhoneApplicationService dictionary is to be used to come out of Tombstoning.
Try these two articles for better understanding:

Each time, when we type the key-words in Google, how does Google give us its answers?
I want to know the process of how Google process our requests.
Personally, I assume that:
1.there are a huge amount of queries sent to Google, in order to respond ASAP, Google gotta have some kinda distributed system, right?
2.also, I think there are some kind of cache systems to speed up Google's response speed, right?
3.If cache indeed exists, what is stored in that cache? Could it be some kind of <key, value> pair? Cuz I guess that, it's <key-words, url>. But would be it be too expensive to cache url directly, because each url will probably take up many memory, right?
UPDATE:
After skimming the keynote suggested by #Gregory Pakosz, I wondering what the Cache Server is responsible for and what the Cache Server caches?
Jeff Dean's 2009 keynote: Challenges in Building Large-Scale Information Retrieval Systems gives a pretty nice overview of how Google works.

Let me preface with saying that I'm used to using Sequel Pro on a mac for doing my database administration (table creation and inline data editing).
I have now been asked to do some oracle work as well and I'm looking for an Oracle client that has much the same feature set as Sequel Pro.
I must be able to ssh first and log into the database second. Edit data in a table view and be able to run queries easily.
The only product I've found on my own has been navicat. However its workflow has been driving me up a wall. :)
Any recommendations? keeping under 500 bucks would be nice... I know about Toad but it's wickedly expensive and I'd like to hold off on asking for that if there is an adequate substitute. :)
Thank you,

SQL Developer... It won't do the SSH stuff natively, though. But for all the other tasks it's pretty awesome for free.
