WMF Projects/Upgrade Payments Infrastructure

Upgrade our payments server Team members: Tomasz Finc (project manager) , Arthur Richards (developer)

Feature justification

Current payment server is not scaling

User requirements

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

Specification

Upgrade payments server with the following

• APC
• Squid
• LVS
• Memcache

Software design document

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

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.
