Technical Description of TaxCloud
TaxCloud operates on a real-time web services API. There are no new data elements to track and store, so that there is zero surface impact on your existing cart system(s). All that is required is an API ID (a TaxCloud generated "username" for your cart) and an API Key (a TaxCloud generated secure password for your cart). That’s all. There’s no software package to install or update and no database to maintain.
TaxCloud relies upon on-demand and reserved computing infrastructure provided by Amazon.com's Elastic Computing Cloud (EC2) services.
EC2 was first introduced in 2006 and, after extensive testing, went live in November 2008. Because we designed TaxCloud specifically for an EC2 environment, the service can be scaled up or down in real time, based on the volume of transactions, and easily replicated through multiple EC2 Availability Zones (geographically distinct sets of highly available data center facilities) for fault tolerance and disaster recovery.
TaxCloud is safe and secure; all TaxCloud APIs operate only under SSL protocol. In addition, we issue a unique ID and key for every merchant store/shopping cart. We do not store any of your customer data on our servers.
