Selecting a Region
When determining the right Region for your services, data, and applications, consider the following four business factors.
Compliance with data governance and legal requirements
Depending on your company and location, you might need to run your data out of specific areas. For example, if your company requires all of its data to reside within the boundaries of the UK, you would the London Region.
Not all companies have location-specific data regulations, so you might need to focus more on the other three factors.
Proximity to your customers
Selecting a Region that is close to your customers will help you to get content to them faster. For example, your company is based in Washington, DC, and many of your customers live in Singapore. You might consider running your infrastructure in the Northern Virginia Region to be close to company headquarters, and run your applications from the Singapore Region.
Available services within a Region
Sometimes, the closest Region might not have all the features that you want to offer to customers. AWS is frequently innovating by creating new services and expanding on features within existing services. However, making new services available around the world sometimes requires AWS to build out physical hardware one Region at a time.
Suppose that your developers want to build an application that uses Amazon Braket (AWS quantum computing platform). Amazon Braket is not yet available in every AWS region around the would, so developers would have to run it in one of the Regions that already offers it.
Pricing
Suppose that you are considering running applications in both the United States and Brazil. The way Brazil’s tax structure is set up, it might cost 50% more to run the same workload out of the São Paulo Region compared to the Oregon Region. There are several factors determine pricing, but for now we know that the cost of services can vary from Region to Region.
