- An on-premises region with customer premises equipment, devices, scripts, and
API.
- An internet-based connectivity with browser, devices, script, and
API.
- An OCI region with a VCN containing:
- A Bastion subnet with OCI Bastion.
- An application subnet with OCI Kubernetes Engine.
- A cachine layer subnet with OCI Cache wth Valkey.
- A database subnet with Database with PostgreSQL.
- A logging subnet with OCI Search with OpenSearch.
- A dynamic routing gateway (DRG).
- An internet gateway.
- A service gateway.
- An Oracle services network with IAM, Object Storage, API gateway, Cloud
Guard, Key Vault, and Monitoring.
The customer premises equipment has a bi-directional connection to the DRG
via OCI FastConnect. Internet devices have a bi-directional connection to the internet gateway via a web
application firewall.
OCI Bastion goes to OCI Kubernetes Engine, which goes to OCI Search with OpenSearch, Database with PostgreSQL, and OCI Cache
with Valkey, which has a bi-directional connection with the API gateway via cache
hit.
The service gateway also goes to the Oracle services network.
