Amazon lowers EC prices again

February 2nd, 2013 Comments off

Amazon has reduced their on demand EC2 prices. This applies to instances running Linux and is pretty much across the board as far as the type of instance. All M1 (first gen), M2 (high memory), M3 (second gen) and C1 (high CPU) instances are affected.

The reductions average 10-20%.

Here’s a table from the Amazon AWS blog.

 

  Savings (%)
Region M1 M2 M3 C1 Medium C1 Extra Large
 US East (Northern Virginia) 7.7% 8.9% 13.8% 12.1% 12.1%
 US West (Northern California) 27.7% 9.1% 11.3% 11.3%
 US West (Oregon) 7.7% 8.9% 12.1% 12.1%
 AWS GovCloud (US) 22.3% 9.3% 9.8% 9.8%
 Europe (Ireland) 23.5% 9.1% 11.3% 11.3%
 Asia Pacific (Singapore) 5.9% 2.2% 1.6% 1.9%
 Asia Pacific (Tokyo) 4.3% 2.5% 2.6% 2.6%
 Asia Pacific (Sydney) 5.9% 2.2% 1.6% 1.9%
 South America (São Paulo) 30.4% 20.6% 13.0% 13.0%

They are also reducing data transfer prices. This reduction only applies in region to region data transfers and not to internet connected transfers. So, if you are redundant between multiple regions (say, for failover), maintaining that redundancy is now cheaper. Moving from one region into another region was already free. This is relates to the price you pay for data leaving a region.

 

Here’s the table from the same post as above.

Region Old Price / GB New Price / GB Savings
US East (Northern Virginia) $0.120 $0.020 83%
US West (Northern California) $0.120 $0.020 83%
US West (Oregon) $0.120 $0.020 83%
AWS GovCloud (US) $0.155 $0.030 81%
Europe (Ireland) $0.120 $0.020 83%
Asia Pacific (Singapore) $0.190 $0.090 53%
Asia Pacific (Tokyo) $0.200 $0.090 55%
Asia Pacific (Sydney) $0.190 $0.140 26%
South America (São Paulo) $0.250 $0.160 36%

The data transfer is not just EC2. It applies to EC2, S3, Glacier, and CloudFront.

Jeff Bezos provides an example savings:

Let’s work through an example to see what this means in practice. Suppose you are delivering 100 TB of content per month to your users, with a 10% cache miss rate (90% of the requests are delivered from a cached copy in a CloudFront edge location), and that this content comes from the Standard or Europe (Ireland) Amazon S3 Region. The cost of your origin fetches (from CloudFront to S3) will drop from $1,228.68 to $204.80, an 83% reduction.

 

Amazon AWS was pretty much the first and is still the eader, both in functionality and price. I do 99% of my cloud computing there.

 

Amazon Web Services – CloudFront Overview

April 22nd, 2009 2 comments

CloudFront

Amazon CloudFront is Amazon’s Content Delivery Network (CDN). A CDN puts very large servers with high throughput at the edge of the network. That means that a CDN provider put cached data in multiple locations through out the network (internet). Requests for data are routed to a local server cache instead of the main server at a host. This improves performance, customer experience and possibly even costs (via lower bandwidth requirements).

An example would be a company that serves many pages to many users. Rather than have all of the pages stored in a central location and be accessed by many people all at once, the pages are distributed throughout the network and sit on many different servers. Akamai does this for Yahoo and many other companies. Limelight is another very large competitor in this space.

CloudFront does the same thing and uses S3 storage as the central repository. Upload the files that you want served to S3 and sign up for CloudFront. Call and API and then use the domain name assigned by the API in your web pages. Amazon will automatically replicate your data (identified by you) to multiple edge locations world wide and re-route requests to the users nearest edge location.

Cost

Storage is cheaper in the US and Europe than in Asian locations. You pay normal S3 prices for the storage of your source files. You don’t pay for storage in the edge servers. Instead you pay for the data transfers out of the Amazon network.

You also pay for data requests (each access). Edge servers only support GET requests.

These prices are accurate as of the time of writing them. As always, verify before making a decision.

SLA

Amazon does not currently have an SLA for CloudFront. I would expect that to change at some point but you should keep it in mind when choosing you content delivery network.
