•
You have determined the number of management and media interfaces you want
for each instance.
•
All subnets are configured. Each OCSBC management and media interface
requires its own unique subnet.
When deploying within an AWS VPC, AWS provides a predefined DNS Server IP. This
means that you must use caution when determining your service networks. AWS
predetermines this address as the VPC CIDR range +2.
For example, if AWS provides you with a VPC CIDR Range of 10.8.0.0/16, it also
provides the DNS IP as 10.8.0.2 using DHCP. If you have configured any media or HA
subnet such that it overlaps this network, such as 10.8.0.0/22, the OCSBC sends DNS
requests out that interface, which eventually fail.
Your EC2 workspace may present dialogs and fields that differ from this procedure.
For full information on deploying EC2 instances, see the Amazon EC2 documentation.
Generate an EC2 AMI from the vSBC Image
You perform this procedure to convert the Oracle Communications Session Border
Controller (OCSBC) image provided by Oracle into an AMI, from which you can create
vSBC machines.
This procedure requires that you, from the EC2 system, create a Linux machine,
attach a new disk to it, and put the OCSBC image on your machine. Next, use the
Linux command line to convert the image from qemu to raw format, then perform a
data definition (dd) procedure to write the disk image. Finally, you create a snapshot of
the disk and convert the snapshot to an AMI image. You can create vSBCs from this
AMI.
1.
Launch an instance of the Red Hat Enterprise Linux 7.3 (HVM) with a Public IP for
ssh access. You must create this Linux instance in the same Availability Zone as
your second disk volums.
2.
Attach a second disk volume of 20GB to the VM instance, as a known device
(e.g. /dev/xvdb). Create this disk using volume type General Purpose SSD (gp2).
3.
Download your OCSBC image via Oracle support. The correct image name is
appended with -img-vm_kvm.tgz.
4.
Copy the KVM release image to the target VM.
scp -i "Oracle.pem" nnSCZ830-img-vm_kvm.tgz ec2-user@public_ip_addr:
5.
ssh into the target VM.
ssh -i "Oracle.pem" ec2-user@public_ip_addr
6.
Extract the qcow2 disk imagie from the release package. The command line below
uses version 8.3.0 as an example.
tar xvfz nnSCZ830-img-vm_kvm.tgz
