Clinic setup - 2 frontdesk users, 2 doctors (4 users)* Smaller clinic setup - 1 frontdesk user, 1 doctor (2 users)* |
Cost Estimation Sheet with Results
Comprehensive approximate estimates are found test results and calculation estimates can be viewed in this document: Bahmni Lite Setup and Cost Estimation
The following below analysis explains the various design factors that were taken into consideration during the estimation above performance test calculation process.
Lesser clinics cluster (approx 40 concurrent users)
| Info |
|---|
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. |
Hardware
Node (EC2: t3-large)
RAM 8GB
2 vCPU
AWS LINUX x86_64
Max pods supported: 35
Database (AWS RDS service: db.t3.xlarge)
...
2 users clinic setup (maximum*)
1 to 24 clinics

m5.xlarge instance is suggested for Bahmni lite implementation on this setup since both the CPU and RAM availability is twice than t3.large and supports upto 58 kubernetes pods. |
Hardware
Node (EC2: m5-xlarge)
RAM 16GB
4 vCPU
AWS LINUX x86_64
Max pods supported: 58
Database (AWS RDS service: db.t3.xlarge)
