Deployment over Kubernetes requires an assessment of the data center and existing services. Below are the main services:

Mandatory:

• Kubernetes

• Object storage (S3)

• Managed Database (MySQL ( or Postgres)Object storage (S3)

Optional:

• DNS zone controller (optional)

• ELK or EFK (logging, optional)

• Prometheus and Grafana (monitoring, optional)

The deployment is performed using Helm Charts.

...

1. Kubernetes - preferred Opinshift 1.28

2. Object storage - S3 compatible, like MINIO

3. Database - preferred MySQL 5.7, minimum 2 cores, 16GB

4. Separate VM (Jump host) - minimum 2 cores, 16GB

Hardware requirements for 1,000 ONVIF cameras

1. Computing and virtualization - 20 instances with 2 vCPU, 8GB each. It means we need a minimum of 40 threads = 20 cores with 160 GB of memory. It could be, for example, 1 Xeon with 28 cores (56 threads) and 256 GB. The overhead is for running Kubernetes.

2. Storage – 350 TB object storage. One camera with 1Mbps and 30 days retention is 0.33TB which results in ~ 350 TB. The storage server must support an object storage interface (S3).

3. Database – 2 core, 16GB RAM, 60GB storage. A database server must have an automatic backup.
