EC2 Reserved Instances
Posted by Lars Schenk in Virtualisierung on März 16th, 2009
With “Reserved Instances” Amazon introduced an additional pricing option for EC2 that gives an option to make a one-time payment for an instance to reserve capacity and further reduce hourly usage charges. You may look up the details at: aws.amazon.com/ec2/#pricing.
I have made a rough comparison for the classic “on demand” small instance against the new reserved instance:
On Demand Instance:
$0 + (365*24*$0,10) = $876/year = $73/month
Reserved Instance 1year:
$325 + (365*24*$0,03) = $588/year = $50/month
Saves you $288/year or $24/month.
Reserved Instance 3years:
$500 + (3*365*24*$0,03) = $1288/3years = $430/year = $36/month
Saves you 446 $/year or 37$/month.
Here’s the offical FAQ on using Reserved Instances. And here’s a funny but critically blog post about the “single commandline that can costs you losts of money“. I think Marc Musings is right and I wish that Amazon would improve this because I had the same bad emotions with this “new API feature”. It would basically a good idea to have alerts and/or limits for charges, instances and traffic.
Can’t wait for reserved Instances to be available for the EU region… “in the near future” as Amazon promised… Happy emotions when spending big money with ec2-purchase-reserved-instances-offering!
UPDATE 09-08-21: New Lower Prices for Amazon EC2 Reserved Instances and I’m also happy to see that one of my EC2 instance hit the 500 days uptime mark.
Cloud Computing – DLD09
Posted by Lars Schenk in Video, Virtualisierung on Januar 28th, 2009
If I had to convince a non technical person about Cloud Computing, I would show him this video.
I really enjoyed listening to Dr. Werner Vogels. Dr. Vogels is Vice President & Chief Technology Officer at Amazon.com where he is responsible for driving the company’s technology vision, which is to continuously enhance the innovation on behalf of Amazon’s customers at a global scale.
This vision is why I have moved to EC2/S3 in 2007. I guess, I’ve finally become an Amazon AWS fan boy.
Even if audio is a bit out of sync, it’s worth to listening this long session.
As a developer from the bottom of my heart I like especially this quote: “There is no value in being a system administrator. You do not build a better product by being a better server maintainer.” This is so true, but I wonder how EC2 can free me from typical administration tasks. I still have to maintain my virtual server instances with the whole LAMP stack. Plus I have to think about how to scale horizontally (what to do when I need more virtual server instances).
In contradiction to Amzon’s EC2, Google’s AppEngine promises to free me from doing the admin tasks (no OS/LAMP Stack to maintain) and to solve the scale problem (no Database Replication to set up). AppEngine scales out of the box – the downside is, that it offers a very limited runtime just for you app.
True, a single EC2 instance doesn’t scale out of the box but it also doesn’t limit you in doing what you want to do on your virtual server. With EC2 I have to solve the scaling on my own. For this price I got more freedom.
I’m exited to use and learn about EC2/S3/Storefront each day but I also hope that Google’s AppEngine will offer a wider range of runtime environments in the future. t’s an interesting Cloud-Year 2009! #buzzword
