This image shows a tenancy with an Oracle Cloud Infrastructure (OCI) Region having OpenSearch, IAM, Vault, and three availability domains inside a Compartment. The availability domains have the following components inside a VCN:

• Public Subnet (10.3.31.0/24) with a Load Balancer across all three availability domains.
• Private subnet (10.0.32.0/24) with a VM instance, Filebeat output, and Logstash instance in Availability Domain 1 and Availability Domain 3.
• Public Subnet (10.0.30.0/24) with a Bastion host in Availability Domain 2.

The user accesses the VCN via a WAF and an Internet Gateway.

A Customer Data Center with Servers connects to the Logstash instance via Site to Site VPN and a Dynamic Routing Gateway.
