Server Hardware Requirements

Overview

MOSIP deployment is split into two distinct parts:

1. ID lifecycle managament

   • Pre-registration

   • Registration

2. ID Authentication

The server side hardware estimates for the above are specified at a high level in terms of compute (Virtual CPU, RAM) and storage requirements. We provide estimates for MOSIP core modules only. External components are not in the scope. See Exclusions.

The variables that largely determine the hardware requirements are:

1. Population of a country

2. Rate of enrollment

3. Usage of foundation ID by various services

Pre-registration

Refer to Pre-registration Resource Calculator XLS

Allow for 20% additional compute and storage for monitoring and any overheads.

Registration (enrollment)

The registration compute resources are related to the max rate of enrollment desired. The processing throughput must match the enrollment rate to avoid pile up of pending registration packets.

The data here is based on actual field data of a MOSIP deployment.

Assumptions:

• Rate of enrollment: 216000 per day

• Average packet size: 2MB

• Biometric modalities: Finger, iris, face

• Pod replication as given here.(TBD)

Compute requirements for registration

• Configuration of compute node: 8 VCPU, 64GB RAM, 64GB disk store.

• Number of nodes: 21

Resource	Per node	Nodes	Total
VCPU	8	21	168
RAM (GB)	64	21	1344
Node disk (GB)	64	21	1344

Storage requirements for registration

Storage is dependent on population of a country (i.e. the number of UINs to be issued). Storage requirements for various types of data are listed below.

Data	Storage	Comments
Object Store (S3/Minio)	3200 GB/million packets/replication	Replication factor to be applied based on replication strategy
Postgres storage	30 GB/million packets	Includes all databases
Landing zone	Unprocessed packets X avg packet size	The size of landing zone depends on the estimated lag in packet processing and packet uploads. Once UINs are issued, the packets may be removed from the landing zone as a copy is already saved in Object Store
Logs (Elasticsearch)	80 GB/day	Logs maybe archived after, say, 2 weeks
Monitoring (Prometheus)	1.2 GB/day
Kafka	TBD
ActiveMQ	TBD
Redis	TBD

ID authentication

Refer to IDA Resource Calculator XLS

Allow for 20% additional compute and storage for monitoring and any overheads.

Exclusions

The compute and storage estimates for following components are not included:

Component	Comments
Postgres	Only storage estimated above.
Object store	Only storage estimated above.
Bio SDK
HSM
ABIS
Antvirus (AV)	Default scanner (ClamAV) in included, however, if you integrate your AV, the same needs to be estimated.
Load balancers
External IAM (for Rancher)
Disaster recovery(DR)

DR would significantly increase compute and storage requirements. It is expected that System Integrator works out the appropriate DR strategy and arrives at an estimate.
