+# eSignet Resource Calculator - Mock IDA
+
+This Resource Calculator is designed to help estimate the CPU, RAM, and Storage required for deploying the eSignet system in a given country or environment. The calculator leverages key assumptions, performance data, and buffer considerations to provide a comprehensive and scalable resource plan.
+
+---
+
+## 1. Overview
+
+The **eSignet Resource Calculator** is intended to guide the teams in planning and provisioning resources for eSignet deployments. The data is based on:
+- Country-specific population and usage metrics.
+- Performance benchmarks from the eSignet team.
+- Calculations for necessary buffers (monitoring, logging, Kubernetes overhead, etc.).
+
+> **Legend:**
+> - Blue: Data added by country
+> - Green: Data added by performance team
+> - Orange: Data calculated as per country input
+
+---
+
+## 2. Data Inputs
+
+### To Be Provided by Country
+
+| Assumptions                                                                    | Example Value  |
+|--------------------------------------------------------------------------------|:--------------:|
+| Total Population Having Registered National ID                                 | 4,000,000      |
+| Percentage of Population using National ID for authentication                  | 50%            |
+| Percentage of Population using National ID for authentication during peak hour | 50%  |
+
+These values should be customized for your country's context.
+
+---
+
+## 3. Population based on the data provided
+
+- **Total Population using National ID for authentication:**  
+  `Registered Population × % Using for Authentication`  
+  _Example:_ 4,000,000 × 50% = 2,000,000
+
+- **Total Population using National ID for authentication during peak hour:**  
+  `Population using for Authentication × % During Peak Hour`  
+  _Example:_ 2,000,000 × 50% = 1,000,000
+
+- **Expected Peak Hour TPS (Transactions Per Second):**  
+  `Total Population using National ID for authentication during peak hour/3600`  
+  _Example:_ 1,000,000 / 3600 = 277.77 = 278(approx.)
+
+---
+
+## 4. Total TPS and Resources Used during eSignet Performance execution
+This section is about the performance baselines considerations for 100TPS performance run. 
+
+i.e for the current resource calculator it is 106 virtual users and 1 relying party completing 25000 OIDC flows, matching the expected peak hour TPS of 278 with a factor of 3.
+
+---
+
+## 5. Computations for the total resources required
+To support a workload of 100 transactions per second (TPS) and accommodate peak hour demands, a comprehensive service-wise resource breakdown is shown in the report.
+
+To ensure system reliability and operational readiness, buffer allocations were added to 
+Monitoring, Logging, and Alerts, Kubernetes Infrastructure, System Buffer.
+
+Combining all components, the total resources required ensuring robust performance and scalability under peak conditions are shown.
+
+---
+
+## 6. Storage
+The Postgres DB size is computed considering, 1 user per relying party consumes 2.5KB of size to store user consent for total OIDC flows and factor to match peak hour TPS (OIDC flows x 2.5 KB x factor) 
+
+Maximum memory recorded in redis cache for total OIDC flows along with 20% buffer is considered for redis cache computations.
+
+Logs size is computed considering logs generated for total OIDC flows and calculated per OIDC flow.
+
+Startup & Liveness Logs is the logs generated while bringing up the esignet service.
+
+> **Note:** Additional storage may be required for infra logging and system buffer. The calculator provides estimates, but actual sizing should be validated in production or enterprise environments.
+
+---
+
+## 7. Usage Instructions
+
+1. **Input Data:**  
+   Update the input assumptions according to your country's statistics.
+
+2. **Review Calculations:**  
+   The calculator will automatically compute the required resources based on your inputs.
+
+3. **Interpret Results:**  
+   Use the computed vCPU, RAM, and storage requirements to plan your cloud or on-premise infrastructure.
+
+4. **Buffer Appropriately:**  
+   The calculator includes buffer recommendations, but you may adjust them based on your operational policies.
