Our systems are securely hosted in Google Cloud's infrastructure (similar to Shopify), leveraging the elastic scalability and economic benefits of cloud computing. Our primary data centers are in the UK & Europe. Where possible we use Google-managed services for the underlying systems instead of operating them ourselves. Where we have not been able to use Google provided services, such as the maintenance of the servers hosting the SparkLayer application, all operational aspects have been automated. This means we are able to scale automatically to meet increased traffic demands, and self-heal in the event of a failure.
