Hello i have searched far and wide for a way to do this,
we are a small company that has our server hosted at amazon with an ec2 instance, we have recently bought a new server to keep at our office for testing purposes.
is there any easy way to create an image or use amazons AMI to make a complete backup/duplicate of the server? all log files and temporary files is not important i just need the system that has been developed for us to run independently on our new server.
any help is very much appreciated because we only got very little knowledge in this area ourselves but we are learning fast as well! :)
thanks in advance!

Folks,
I had a quick question about Amazon EC2, I have been recently using it for doing some data mining for scientific research(genetics). I do all my work on a Linux instance, but I also noticed that amazon lets you launch a windows instance there. I am just curious to know how does the licensing work for this, am I already paying for this as part of my AWS bill?
Thanks a lot.
EC2 pricing includes your Windows licence fees, hence why they are more expensive than Linux instances.
Some instance types also include SQL Server licenses but you are free to use your own licenses if you have them.
Full details are on the AWS EC2 pricing page.
Considering you're a startup with no funds for own server farm. Which existing solution can give you a peace of mind that any sudden increase in traffic won't bring everything down.
I know it's not just up to hardware, so we plan to have at least a load balancer, memcache and few db servers.
Is it possible to have a setup on AWS that would automatically add instances and bandwidth if the traffic increases?
What other advice you could give to deployment noobs? Thanks.
ps: I apologize in advance if a question is too broad or reflects inexperience on mentioned topics, but that's why I ask.
Heroku. Because you're a start-up, keep things lean and it doesn't get leaner than almost free (with 1 dyno + small shared DB). Spend time building your product, not on the infrastructure. You don't want to be installing patches when you should be talking to customers. Heroku is also flexible and allows you to scale up 'dynos' as your traffic increases so no worries about growing there. Heroku won't scale automatically for you, though, so do your own server monitoring. Heroku add-ons are also nice.
Recently we have done a very good comparison between AWS and Heroku and we decided to move to Heroku, here is the detail of this http://www.confiz.com/blog/tech-session/selecting-the-right-cloud-platform/
If you're on Python, you can try Google App Engine.
Migrating the Python app from one platform to another isn't too difficult once you get the past the learning curve as to what features is (not) available. GAE offers datastore, memcache, blobstore plus a few other goodies like dJango and Jinja (templating). Worth checking the Python start page and it didn't take me long to integrate it into Facebook and Dropbox too.
Stay away from Heroku. You can get EC2 for free for a year from Amazon. Scaling up heroku is extremely costly. Their pricing tends to be unclear and their customer service in general sucks.
BitNami for Amazon EC2 includes ready-to-run versions of Apache, MySQL, PostgreSQL, SQLite, Python, Django, Git, their required dependencies, and much more. It can be deployed via all-in-one free native installers, virtual machines and Cloud Images. maybe worth checking out.
My personal experience is that you should generally start with Heroku. Get your app out in the wild and find that product/market-fit or some type of traction. You will know you are going somewhere because customers will cause scaling issues. In this case, Heroku will allow you to scale with very little overhead. And for some time, this scaling will not hit you in the wallet.
Jump to AWS when you are ready. When will you be ready? When you have enough pain, in the wallet, where you need more control over the stack. You can hire a AWS devops type or learn about it, yourself.
Both Heroku and AWS have auto-scaling solutions, but whereas Heroku has a fairly flat learning curve -- that is what you are paying for -- AWS can get broad and steep fairly quickly. A Udemy AWS course or any of the hundred other online resources will get your started down building a robust AWS architecture.
Lastly, while performance should not be your primary concern, make sure that you are using best practices in your code. Your first user should not bring your system to a crawl. And AWS will not help if she does.
Hope this helps in some way.
This has been my experience. My saas start kits are built to deploy to Heroku out of the box for this reason. However, the start kits are also containerized. I know that you spoke of AWS explicitly, but with containers you can be infrastructure agnostic. This is worth considering!

Check out this blog series I'm starting because I found Heroku to not be scalable at all from a financial perspective compared to EC2 and Digital Ocean. Going to be showing how to put a Ruby application on Digital Ocean using Docker, which allows you the same flexibility and ability to scale up and down very quickly https://medium.com/#karimbutt/weaning-off-heroku-part-1-b7f123ae855f
It greatly depeneds whether you're looking for a PaaS, IaaS or SaaS, and what is the language you using.
AWS is a IAAS/PAAS with multiple components and layers.
Heroku is a PAAS supporting multiple languages, most notably Java, Ruby and Node.js
Other platforms come into play depending on your needs, you might want to take a look at this comparison as well: https://dictativ.com/compare/paas
I'd like to host some php or perl/cgi script, without having a full blown web site, does anybody know someone is offering this kind of service, free, hopefully.
Thanks,
David
you can sign up for a developer account with Amazon Web Services and get a server instance of your choice for free for one year - http://aws.amazon.com/
You could run your own Linux or Windows webserver - both are completely capable of hosting as simple or complex a site you want. Unless you want to make this script available for others to use as a service, there's no need to find an "outside" provider.
Hmm, Free File Hosting. Or, if you don't need to actually access the files from anywhere, and you just want them hosted somewhere, gist might work well for you.
I just found out about amazon EC2. I am wondering what it actually offers. I use to go with VPS servers and now I want to learn if EC2 give me the same options as a VPS with some host company.
Are there any limitations on what I can install?
Thanks
Cristian
Probably the main difference between EC2 and a conventional VPS hosting service is the pricing model. EC2 charges for CPU time (and other resources) by the hour, whereas many conventional services charge by the month (or greater). The best way to learn about EC2 would be to jump into the documentation, and then sign up for the free usage tier.
Within reason, there are no limitations on what you can install.
