 #### Networking
 
 Networking is the cornerstone of an OCI architecture and a unique characteristic of OCI Gen2 cloud. In simple terms Oracle offers to customers a flat network topology built on a highly scalable physical network which is not oversubscribed. Storage and network IO is moved out of the hypervisor into the custom firmware on the physical NICs (Network Interface Card), and that enables lower overhead.
 
-This off-box network is virtualized separately to the infrastructure and the “Oracle Code” and that gives customers a guaranteed maximum of 2 hops between any services ran on Oracle Network Fabric and protection from issues like the “noisy-neighbour”.

 - __Dynamic Routing Gateway (DRG)__: The DRG is a virtual router that provides a path for private network traffic between VCNs, or a network outside the region, an on-premises network, or a network with another cloud provider such as AWS or Azure.
 - __Local Peering Gateway (LPG)__: LPGs enable to peer one VCN with another VCN in the same region. Peering means the VCNs communicate using private IP addresses, without the traffic traversing the internet or routing through your on-premises network. This feature can still be used, however best practice is to now use the upgraded DRG for this as it simplifies the network configuration. LPG is now only needed for extreme low latency requirements.
 
-- __Load balancer__: A load balancer improves resource utilization, facilitates scaling, and helps ensure high availability. The Oracle Cloud Infrastructure Load Balancing service provides automated traffic distribution from one entry point to multiple servers reachable from the VCN. In OCI this is a managed service. It offers a load balancer with your choice of a public or private IP address, and provisioned bandwidth.

 A load balancer (LB) protects backends, improves resource utilisation (SSL-offloading), facilitates scaling, and helps ensure high availability. A customer can configure multiple load balancing policies and application-specific “health checks” to ensure that the load balancer directs traffic only to healthy instances. The load balancer can reduce the customer's maintenance window by draining traffic from an unhealthy application server before it is removed from service for maintenance.
 
@@ -430,7 +430,7 @@ For additional information see the [public documentation](https://docs.oracle.co
 Each Load Balancer has different entry points to further route traffic to specific back-end servers and ports in OCI. These are called backend sets. The Load Balancers will not do SSL tunnelling for the HTTP traffic, but terminate the SSL traffic from the client. The traffic between the Load Balancer and the backend host(s) will therefore not be encrypted.
 
 - __Subnet__: A subnet is a segment of a VCN and any online OCI resource is associated with a specific subnet. A subnet reserves a subset (less significant bits) of the IP addresses allocated to the VCN (following the CIDR notation), can be specific to an Availability Domain or to a region (regional subnet), can be private or public (accessible by Internet) and is secured with the Security List and Routing Table components.

+
 - __Security List (SL)__: Each subnet and/or host will have security rules that specify the source, destination, and type of traffic that must be allowed in and out of the subnet. In simple terms an SL is a virtual firewall for each subnet/VCN controlling ingress and egress traffic.

This will be used during implementation and Security Lists created with the actual implementation values.

 All single-node DB systems support the following Oracle DBCS editions: Standard Edition, Enterprise Edition (EE), EE - High Performance, EE - Extreme Performance. Two-node Oracle RAC DB systems require Oracle Enterprise Edition - Extreme Performance which includes the Real Application Clusters license.
 
 Each database will be single node, [for information see](https://docs.oracle.com/en-us/iaas/Content/Database/Concepts/overview.htm) with ASM as the Storage Management option. By default, the database listener runs on port 1521.

The DB automatic backup configuration is defined in the deployment section of this design. However many customers prefer a more flexible scheduling or want to have access to the backups from outside the DB Service. The DB backup bucket will be created for this purpose.
