The instructions below will explain how to install Mobius Evolver on your own AWS Account. Before you start, you will require:

• an Amazon AWS account

Amazon AWS Cloud Computing

With your AWS account (May 2021):

• you get a free DynamoDB quota every month: 25GB of free storage,
• you get a free Lambda quota every month: 1 million function invocations and 3.2 million seconds (37 days) of computing time, and
• for the the first 12 months after opening your account, you get 5GB of free storage on S3.

This means that you can run large numbers such searches every month without incurring any Lambda costs. You may still incur some storage costs depending on how long you save the results, but these costs are low. (May 2021, S3 storage cost is $0.023 / GB).
