Changes the default route in all routing tables associated with internal networks to point to itself. It is a highly scalable web service that can be used as internal DNS hostings.
In order to be able to automatically make API calls to AWS, the cluster members need to be provided with credentials.
Moves all secondary private IP addresses from the failed cluster member to itself. Put the DHCP IP ahead of the secondary IP. On the primary node, assign secondary private IP addresses for eth 1 (client IP or VIP) and eth 2 (back-end server IP or SNIP) The AWS console automatically assigns primary private IP addresses to the configured NICs. Here is a brief summary that will get you started on using the most recent AWS capabilities.
Failover Event Diagram¶. Internet Gateway: For a subnet to be accessible to the internet an AWS internet gateway is required. Multiple IP addresses are a requirement for multiple SSL certificates and have a variety of other useful applications. ip route add default via
Create a secondary routing table. • The number of secondary private IP addresses you can assign depends on the instance type.
A brief introduction to EC2 networking Every […] You can see Elastic IP addresses with matching tags are associated with the secondary private IP matching the virtual address corresponding to the active BIG-IP device. You must assign more private IP addresses to VIP and SNIP, known as secondary private IP addresses.

[Updated 2018-06-11.] AWS offers Route53, as a part of Amazon’s cloud computing platform, Amazon Web Services (AWS).

Add Multiple private IP addresses to AWS EC2 instance You can add multiple private IP addresses to your EC2 instance. Where 172.31.51.23 is primary private IP acquired by DHCP and 172.31.51.24 is secondary private IP assigned manually to the EC2 instance (multiple addresses are allowed). Secondary CIDR: If all of your organisation’s IP addresses in its VPC are occupied by private subnets, a way around this is to create a secondary CIDR block and launch a public subnet in it. With Route53 you can host multiple internal domain names within your VPC (or group of VPCs) which are visible and accessible to the internal hosts only and blocked for external traffic.
This diagram shows a failover event with CFE implemented in AWS. You can assign multiple IP addresses to an EC 2 instance.
