Welcome to day 8 of the unofficial AWS Cost Optimisation Advent Calendar 2024, where every day we will be sharing new tips or tricks to help you optimise your cloud costs before Christmas 2024.
Just a short one for today, but one that good result in big savings: Regional Pricing.
Many organisations default to launching resources in the region closest to them or their customers.
This is a perfectly sensible approach however not everyone is always aware that AWS has different pricing for different regions. This means that the price varies for the exact same resource from region to region.
As AWS prices everything in USD regardless of region, the price is fairly straightforward to compare.
In some cases the difference can be unexpectedly substantial.
For example if you launch a mac2.metal dedicated host in us-east-1 rather than eu-west-1 you will pay 10% less for the same instance. As these instances are quite expensive that equates to a $600 per annum difference for a single server.
For performance reasons it is always best practice to keep customer facing services as close to your customers as possible, but there may be numerous opportunities for internal or other services to run in the cheapest region.
One important thing to note is that data transfer between regions is not free and should be factored into your decision making process.
Also latency is a key consideration if services you deploy to different regions need to communicate cross region.
The US regions tend to be the cheapest on average for most services.
Some useful resources to check pricing cross region are:
And all the pricing is available on the AWS Pricing Page.
That's it for today, see you tomorrow for another tip!
