OCI Architecture
Regions: Localised Geographic regions comprisiong one or more Availability Domains. Choose based on:
- Close to users for highest performance
- Data compliance
- Service availability
Availability Domains: one or more fault tolerant datacentres located withing a region
- They are very unlikey to fail simultaneously
- Connected to each with high bandwith connections
Fault Domains: Located within an AD, providing a "Logical Datacentre"
- Each AD has 3 FD
- Resources in different FD will not share a single point of hardware failure
- Changes can be specified by FD
- User specifies which FD to use
Design exammple:
- Replicate App tier over 3 FDs in an AD.
- Do the same for the Database tier
- Then duplicate over another ADs (database can be synchronised using Oracle Dataguard)
OCI Ditributed Cloud
Hybrid Cloud Services
- Dedicated Regions: at a customer site
- Oracle Cloud VMware Solution (on OCI public or dedicated)
- Autonomus DB on Exadata Cloud at Customer site
- Roving Edge Infrastructire (OCI compute and storage for remove disconnected scenarios)
Dedicated Regions
- Airgapped, will be installed, maintained and operated by Oracle
- Customer datacentre of choice
- Use cases:
- Data residency
- Latency sensite applications
OCI-Azure Interconnect
- Private interconnect (very low latency < 2ms, 12 interconnects)
- Pricing is based on ports/circuits, no charge for bandwitch copnsumed
- Use case: Run application on Azure, DB on OCI
- Oracle Database Service for Azure
- For Azure customers, they can connect their Azure environments to OCI deployments
- More automated
- Unified monitoring in Azure of OCI data
