All the estimates projected are based on tests performed for 24 hours on single namespace/ single cluster concept with multiple concurrent users and a shared RDS.
Clinic setup - 2 frontdesk users, 2 doctors (4 users)**
Smaller clinic setup - 1 frontdesk user, 1 doctor (2 users)**
Lesser clinics cluster
t3.large instance is suggested for Bahmni lite implementation since the number of active pods may vary from “14 to 22” based on the requirement. t3.large supports upto 35 kubernetes pods and enables seamless deployments.

Bahmni Lite Setup and Cost Estimation
*- The maximum number of clinics are an approximate projection based on the performance test results and the test's higher demand requirement from norm. The maximum estimates should be considered when the average patient visits to the clinics are moderate to semi high.
**- The number of users assumed are based on the number of requests sent by a user on an average to the server and typical clinic setup observed from real time sources.
