Partica is developed and hosted on Microsoft Azure Platform as a service. As such, there is no need to patch the infrastructure:

"Azure PaaS team takes care of the infrastructure health by keeping the infrastructure updated against all the known vulnerabilities for which fixes have been distributed. Since this process is opaque to the developers and is automatic, the risk of information breach resulting from the known vulnerabilities is significantly reduced"


Attached is a diagram of how our environment is setup in Azure - triple redundant storage arrays in two physical locations with both duplicated as a write only backup (which means nothing ever gets deleted from the backup even if it is deleted from the main storage).
