I currently try to implement amazon ec2 and I read that after one year they charge you. I used google app engine before(using java) and there is the feature that you can enable/disable charging. I just want to try the free ec2 instance, so here are my questions:
Does Amazon EC2 AUTOMATICALLY charge you after one year?
How to disable the automatically charging function?
I ended up closing my account by visiting the account page
At the bottom of the page you will find "close account"
It is currently not possible to disable charging. You might need to go over the free tier (for example if you setup a production environment, you might not want it to be killed automatically by amazon). Google App engine is a bit different because it is free if you have zero http requests, so it will just stop serving your app.
If you delete your credit card on your account, amazon will still charge it if there is an unpaid balance.
Amazon will not remind you that you will go over your free tier, so I would recommend to put a little reminder in one year on your calendar in one year to not forget to shutdown your server.
There is no way to control how much you will have to pay on AWS, that's why I wouldn't use it.
Amazon is really vague on the free tier (for instance it's not very clear whether the storage volume comes with the instance is counted against free EB2 storage quota). There are so many ways you can get a bill for using the free tier.
Yes you will be billed after 12 months, if you don't terminate all the instances and detach all storage volumes.
So many people have complained about Amazon's billing practice. Amazon has never changed. I guess this is the way Amazon decided to make $. Let you in for "free" but you will most likely accidentally spend some money. If you decide to use it, you won't know how much you will have to pay. If you have the capability to use colo/dedicated server, you might find out it's actually so much cheaper to go with a fixed monthly payment instead of billing based on usage.
With Amazon EC2, you are billed per hour of usage. If you are a new user, your account is credited with something like 8,760 free hours (24*365) which expire after 1 year. (I'm working from fuzzy memory here, so double-check the official terms instead of taking my word for it.)
After your free hours expire or are otherwise used up, Amazon EC2 will begin billing for normal hours (which can be as cheap as 2 cents per hour -- http://ec2instances.info). There is no such thing as a "free" EC2 instance.
So, to answer your questions:
Does Amazon EC2 AUTOMATICALLY charge you after one year?
Once your free hours are used up or expire, then you are automatically billed for normal hourly usage.
How to disable the automatically charging function?
You can't. All EC2 instances cost money. You are responsible for keeping an eye on your account and ensuring that you don't go over your free hours if you don't want to pay anything.
I was charged for a service that practically i never used.
a) Its true that Amazon never told you that the free tier is done. However, Amazon is prompty to charges you. Its my mistake but i admit that a little advice doesn't hurt, specially since practicaly everybody do that.
b) Even for a free tier, i wasn't impressed with the performance. I am owned a shared-hosting that are more powerful.
c) As some comments said, you can't delete your credit card, neither you can cancels the service. Its really low.
d) Finally,as some comment said, i closed my account. As far i can remember, its not tied with your Amazon (not cloud) account.
The service its so convoluted and overly complex, its filled with paid-traps and i am not impressed at all. Thanks Amazon but not thanks, i will stick with VPS/Dedicated.
You get 1 year of free usage http://aws.amazon.com/free/ .

I want to run an server for an application I have.
I'm a complete beginner with AWS, so bear with me.
There will be about 50 users (all from the same time zone) that will be accessing the server and I would like to have near 100% availability.
The application I have requires 2 processors and 2GB ram.
I could pay for a machine 24/7 or even only 18 hours a day, assuming I turn it off at night, but I there will be some days where the server is not used at all.
I was wondering if the following is possible: when amazon detects that someone is requesting something from my server, it turns it on in real time, and then forwards the request to my server. After say 5 minutes of no activity, it will turn my server off. This way I can only pay for hours when there is traffic.
Is this possible?
How have people solved similar problems?
No this isn't possible. There is nothing built into AWS to detect traffic and start an EC2 server like you suggest. Plus the startup time on an EC2 server is at least a couple minutes, so those first incoming requests would have to wait a really long time.
You might want to look into running multiple small servers instead of a single larger server. AWS does have the ability to balance the load across multiple servers and add/remove servers from the pool based on traffic. You could have as few as one server running when there is no traffic, and have more servers automatically created as load increases. Look into the AWS Elastic Beanstalk service for this.
If you want to run a truly "serverless" environment where you only pay for compute cycles in milliseconds, instead of servers by the hour, you could look into using AWS Lambda. If you can architect your system to run on Lambda you are almost guaranteed to save costs, but it can be a real challenge to convert an existing system to this sort of architecture.
If you want to look outside AWS you might find something more along the lines of what you describe with Google App Engine. Heroku's free tier also works similarly to your description, but as soon as you outgrow the free tier you have to upgrade to always-running instances.
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.
Is it possible to have multiple users to manage an Amazon EC2 environment? I want to give access to several additional people to create machines on my existing billing account.
Amazon just announced AWS Identity and Access Management - http://aws.amazon.com/iam/
As of right now, it's in 'preview' mode, but this will allow you to have multiple AWS management accounts.
A few months ago Amazon announced Consolidated Billing. I never used it, but I think that is what you're looking for:
Consolidated Billing enables you to see a combined view of AWS costs incurred by all accounts in your department or company, as well as obtain a detailed cost report for each individual AWS account associated with your paying account. Consolidated Billing may also lower your overall costs since the rolled up usage across all of your accounts could help you reach lower-priced volume tiers more quickly.
Consolidated Billing Guide
This is absolutely possible using IAM service of AWS. With the help of IAM you can create users and give them specific permissions on various services of amazon.
You can try http://LabSlice.com. It's primarily for Virtual Lab Management (ie. playground environments), but may suit your needs.
I want to set up a Windows Azure account.
I'm an MSDN Subscriber so I get it for "free" the first 16 months.
Still, Microsoft want my credit card number just in case I go over the free limit.
In theory, this means I'm writing a carte blanche to MS to bill my credit card.
I want to know if anyone has been using Azure and if there's anyway of setting it to simply stop working if it gets near the cap where it would start to cost me something??
Today, there are no usage caps you can place on your account. Regarding the credit card and carte blanche ability to bill you: you'd only be billed for overage beyond the "free" stuff. Microsoft recently instituted an email-alert feature that lets you know when you've used 75% of your available resources. I believe that went live a few weeks ago.
Simply put: you get 750 compute-hours monthly (metered on a 1-hour boundary). This gives you enough hours to run a single, small instance 24x7, as there are just under 750 hours in a month. If you leave two instances running full-time, you'll go over your allotment and be charged.
If you're just learning, the MSDN account is fantastic. Just remember to delete your deployment at the end of the day (or when you're done trying something out), instead of letting it run 24x7. With a bit of prudence, you'll easily be able to test multi-instance applications and avoid ever being charged.
You can also log into the billing portal from the Azure portal. This shows a very detailed breakdown of your monthly usage, and with a quick scan you'll see how you're doing regarding compute-hours.
I keep mentioning compute-hours but not storage or bandwidth. Unless you're doing some extreme development, I doubt you'll run into any storage or bandwidth overruns. Same goes for SQL Azure - stick with Web Edition databases (and only 3 databases) and you'll have no issue there.
I wrote two blog posts that might also be helpful when thinking about how to manage cost so you don't get charged:
The True Cost of Web and Worker Roles
Staging and Compute-Hour Metering
In addition to David's answer, I would also suggest maximizing your use of the local Azure runtime that comes with the SDK. You can create web & worker roles and blobs/tables/queues. Iterate there until you are happy with how everything works - then publish to the public cloud.
There is no charge for the SDK or the local runtime.
The December 2011 release of Windows Azure introduced a much revamped billing portal which, amongst other things, introduced the ability to cap spend on introductionary accounts and MSDN accounts.
Whilst you still need to provide credit card for your MSDN Account, all accounts are automatically created with spending limit of $0; a limit one can remove from the billing portal.

I have thought a lot recently about the different hosting types that are available out there. We can get pretty decent latency (average) from an EC2 instance in Europe (we're situated in Sweden) and the cost is pretty good. Obviously, the possibility of scaling up and down instances is amazing for us that's in a really expansive phase right now.
From a logical perspective, I also believe that Amazon probably can provide better availability and stability than most hosting companies on the market. Probably it will also outweigh the need of having a phone number to dial when we wonder anything and force us to google the things by ourselves :)
So, what should we be concerned about if we were about to run our web server on EC2? What are the pro's and cons?
To clarify, we will run a pretty standard LAMP configuration with memcached added probably.
Thanks
So, what should we be concerned about if we were about to run our web server on EC2? What are the pro's and cons?
The pros and cons of EC2 are somewhat dependent on your business. Below is a list of issues that I believe affect large organizations:
Separation of duties Your existing company probably has separate networking and server operations teams. With EC2 it may be difficult to separate these concerns. ie. The guy defining your Security Groups (firewall) is probably the same person who can spin up servers.
Home access to your servers Corporate environments are usually administered on-premise or through a Virtual Private Network (VPN) with two-factor authentication. Administrators with access to your EC2 control panel can likely make changes to your environment from home. Note further that your EC2 access keys/accounts may remain available to people who leave or get fired from your company, making home access an even bigger problem...
Difficulty in validating security Some security controls may inadvertently become weak. Within your premises you can be 99% certain that all servers are behind a firewall that restricts any admin access from outside your premises. When you're in the cloud it's a lot more difficult to ensure such controls are in place for all your systems.
Appliances and specialized tools do not go in the cloud Specialized tools cannot go into the cloud. This may impact your security posture. For example, you may have some sort of network intrusion detection appliances sitting in front of on-premise servers, and you will not be able to move these into the cloud.
Legislation and Regulations I am not sure about regulations in your country, but you should be aware of cross-border issues. For example, running European systems on American EC2 soil may open your up to Patriot Act regulations. If you're dealing with credit card numbers or personally identifiable information then you may also have various issues to deal with if infrastructure is outside of your organization.
Organizational processes Who has access to EC2 and what can they do? Can someone spin up an Extra Large machine and install their own software? (Side note: Our company http://LabSlice.com actually adds policies to stop this from happening). How do you backup and restore data? Will you start replicating processes within your company simply because you've got a separate cloud infrastructure?
Auditing challenges Any auditing activities that you normally undertake may be complicated if data is in the cloud. A good example is PCI -- Can you actually always prove data is within your control if it's hosted outside of your environment somewhere in the ether?
Public/private connectivity is a challenge Do you ever need to mix data between your public and private environments? It can become a challenge to send data between these two environments, and to do so securely.
Monitoring and logging You will likely have central systems monitoring your internal environment and collecting logs from your servers. Will you be able to achieve the monitoring and log collection activities if you run servers off-premise?
Penetration testing Some companies run periodic penetration testing activities directly on public infrastructure. I may be mistaken, but I think that running pen testing against Amazon infrastructure is against their contract (which make sense, as they would only see public hacking activity against infrastructure they own).
I believe that EC2 is definitely a good idea for small/medium businesses. They are rarely encumbered by the above issues, and usually Amazon can offer better services than an SMB could achieve themselves. For large organizations EC2 can obviously raise some concerns and issues that are not easily dealt with.

The main negative is that you are fully responsible for ALL server administration. Such as : Security patches, Firewall, Backup, server configuration and optimization.
Amazon will not provide you with any OS or higher level support.
If you would be FULLY comfortable running your own hardware then it can be a great cost savings.
i work in a company and we are hosting with amazon ec2, we are running one high cpu instance and two small instances.
i won't say amazon ec2 is good or bad but just will give you a list of experiences of time
reliability: bad. they have a lot of outages. only segments mostly but yeah...
cost: expensive. its cloud computing and not server hosting! a friend works in a company and they do complex calculations that every day have to be finished at a certain time sharp and the calculation time depends on the amount of data they get... they run some servers themselves and if it gets scarce, they kick in a bunch of ec2's.
thats the perfect use case but if you run a server 24/7 anways, you are better of with a dedicated rootserver
a dedicated root server will give you as well better performance. e.g. disk reads will be faster as it has a local disk!
traffic is expensive too
support: good and fast and flexible, thats definately very ok.
we had a big launch of a product and had a lot of press stuff going on and there were problems with the reverse dns for email sending. the amazon guys got them set up all ripe conform and nice in not time.
amazon s3 hosting service is nice too, if you need it
in europe i would suggest going for a german hosting provider, they have very good connectivity as well.
for example here:
http://www.hetzner.de/de/hosting/produkte_rootserver/eq4/
http://www.ovh.de/produkte/superplan_mini.xml
http://www.server4you.de/root-server/server-details.php?products=0
http://www.hosteurope.de/produkt/Dedicated-Server-Linux-L
http://www.klein-edv.de/rootserver.php
i have hosted with all of them and made good experiences. the best was definately hosteurope, but they are a bit more expensive.
i ran a CDN and had like 40 servers for two years there and never experienced ANY outage on ANY of them.
amazon had 3 outages in the last two months on our segments.
One minus that forced me to move away from Amazon EC2:
spamhaus.org lists whole Amazon EC2 block on the Policy Block List (PBL)
This means that all mail servers using spamhaus.org will report "blocked using zen.dnsbl" in your /var/log/mail.info when sending email.
The server I run uses email to register and reset passwords for users; this does not work any more.
Read more about it at Spamhaus: http://www.spamhaus.org/pbl/query/PBL361340
Summary: Need to send email? Do not use Amazon EC2.
The other con no one has mentioned:
With a stock EC2 server, if an instance goes down, it "goes away." Any information on the local disk is gone, and gone forever. You have the added responsibility of ensuring that any information you want to survive a server restart is persisted off of the EC2 instance (into S3, RDS, EBS, or some other off-server service).
I haven't tried Amazon EC2 in production, but I understand the appeal of it. My main issue with EC2 is that while it does provide a great and affordable way to move all the blinking lights in your server room to the cloud, they don't provide you with a higher level architecture to scale your application as demand increases. That is all left to you to figure out on your own.
This is not an issue for more experienced shops that can maintain all the needed infrastructure by themselves, but I think smaller shops are better served by something more along the lines of Microsoft's Azure or Google's AppEngine: Platforms that enforce constraints on your architecture in return for one-click scalability when you need it.
And I think the importance of quality support cannot be underestimated. Look at the BitBucket blog. It seems that for a while there every other post was about the downtime they had and the long hours it took for Amazon to get back to them with a resolution to their issues.
Compare that to Github, which uses the Rackspace cloud hosting service. I don't use Github, but I understand that they also have their share of downtime. Yet it doesn't seem that any of that downtime is attributed to Rackspace's slow customer support.
Two big pluses come to mind:
1) Cost - With Amazon EC2 you only pay for what you use and the prices are hard to beat. Being able to scale up quickly to meet demands and then later scale down and "return" the unneeded capacity is a huge win depending on your needs / use case.
2) Integration with other Amazon web services - this advantage is often overlooked. Having integration with Amazon SimpleDB or Amazon Relational Data Store means that your data can live separate from the computing power that EC2 provides. This is a huge win that sets EC2 apart from others.
Amazon cloud monitoring service and support is charged extra - the first one is quite useful and you should consider that and the second one too if your app is mission critical.
