Amazon Web Services (AWS (opens in new tab)) has announced that its customers can now create IPv6-only virtual private cloud (VPC) networks.
“This capability is ideal if you have workloads, such as serverless and container applications, that consume a large number of IP addresses,” note (opens in new tab) AWS’ Rohit Aswani and Aditya Santhanam, hailing the announcement as monumental.
The duo add that this new capability is ideal for IP address-hungry workloads, such as serverless and container (opens in new tab) applications. With about 18 quintillion IP addresses on offer, IPv6 can help users break free of the constraints of IPv4 address space.
Reporting on the development, The Register (opens in new tab) notes that all the major cloud players including AWS, Microsoft Azure (opens in new tab), and Google Cloud (opens in new tab) Platform support dual network stacks that support both IPv4 and IPv6 addresses.
However, AWS has outscored its rivals with the launch of this capability to create IPv6-only networks. And there are some real-world advantages to having this capability.
“With this launch, you will be able to meet the requirements for adoption of IPv6-only network environments set by US federal government agencies and minimize the need for translation software or systems, thereby creating a simplified IPv6-only architecture,” explain the duo.
The only requirement that AWS enforces for the use of IPv6-only networks is that the Elastic Compute Cloud (EC2 (opens in new tab)) instances must be built on the Nitro System (opens in new tab), which is AWS’ custom collection of hardware (Nitro card) and software (Nitro hypervisor).
IPv6-only subnets, IPv6-only EC2 instances and Resource-based naming are available for all AWS users at no additional cost.
