obtain the credentials through the metadata and authenticate itself while invoking the API.
As you deploy, follow these guidelines:
1.
Create both OCSBC instances in the same Availability Zone.
2.
Oracle recommends that you use Place Groups of type Spread for launching both
OCSBC instances.
As you configure, follow these guidelines:
1.
On the primary instance of OCSBC, and through the AWS console, configure Secondary
Private IPs to be used as OCSBC virtual IPs.
2.
When required, map Secondary Private IP addressing with Elastic IP addressing.
AWS uses its Access key ID and Secret access key as security credentials. Since these
credentials change periodically, the OCSBC does not cache the information. Instead, the
OCSBC always retrieves and uses the latest information from the metadata. In addition, the
OCSBC retries the API by refreshing the latest security credentials if it receives any error
response indicating the authentication failed.
Create and Deploy OCSBC Instances on EC2
You can deploy the Oracle Communications Session Border Controller (OCSBC) on
Amazon's Elastic Computing (EC2) infrastructure in either standalone or High Availability
(HA) mode. When deployed on this platform, you configure and operate the OCSBC as you
would on any other platform. You deploy the OCSBC to use the environment's IP
infrastructure, including the private and public addressing scheme, and its translation
functions to protect the EC2 management environment from direct exposure to the OCSBC
service delivery environment. These deployments also use EC2's DHCP to establish
consistent, compliant management addressing and flat networking across both management
and service traffic.
Oracle recommends you use AWS enhanced networking for better network I/O throughput.
Refer to your OCSBC Release Notes for your version's supported machine shapes. You can
also refer to AWS resources, including the Enable enhanced networking with the Intel 82599
VF interface on Linux instances web page for key information about enhanced networking,
including the EC2 machine shapes that support it.
Find release-specific requirements and information on this feature in your OCSBC Release
Notes. Find configuration information in the OCSBC ACLI Configuration Guide. If desired,
request information to refine your virtual machine resources configuration to desired
performance from Oracle Support or Sales.
Prerequisites to EC2 Deployment
Prerequisites to this deployment procedure include :
•
You have identified and are deploying to the correct AWS Region. This is typically a
default component of your EC2 Account.
•
You have identified and are deploying to the correct AWS Availability Zone. By
deploying 2 (HA) instances during deployment at the same time, you are ensuring that
both instances reside in the same Availability Zone.
•
An Amazon Virtual Private Cloud (VPC) is configured.
•
A security policy is configured.
