WMF Projects/Upgrade Payments Infrastructure

Feature justification[edit]

Current payment server is not scaling

User requirements[edit]

Be able to serve 100% of our banners with 1click donations at a 3% (best banner) + 2% (variance window)

Specification[edit]

Upgrade payments server with the following

Software design document[edit]

Our goal is to allow for Squid caching of the credit card gateway form and its variants to reduce server load. In order to support this, the software that supports the forms (DonationInterface/payflowpro_gateway extension) will require some rearchitecting.

Test plan[edit]

Use Apache Bench (ab) to determine page load times for the various forms under different load scenarios, with different scaling configurations, compare results to baseline (no LVS/squid/APC) results to determine efficacy.
