Amazon's Virtual Private Cloud Service Goes Live

Amazon Launches Virtual Networking in the cloud

Well not to say I didn't see this coming over a year ago, Amazon has finally seen the light and rolled out a Virtual Private Cloud (VPC). Amazon describes their new Virtual Private Cloud in much the same way we do at Enomaly.

To recap, my original definition of a Virtual Private Cloud (VPC) is as a method for partitioning a public computing utility such as EC2 into quarantined virtual infrastructure. A VPC may encapsulate multiple local and remote resources to appear as a single homogeneous computing environment bridging the ability to securely utilize remote resources as part of an seamless global compute infrastructure. A core component of a VPC is a virtual private network (VPN) and or a virtual LAN (Vlan) in which some of the links between nodes are encrypted and carried by virtual switches.

According to the new VPC website, the "Amazon Virtual Private Cloud (Amazon VPC) is a secure and seamless bridge between a company’s existing IT infrastructure and the AWS cloud. Amazon VPC enables enterprises to connect their existing infrastructure to a set of isolated AWS compute resources via a Virtual Private Network (VPN) connection, and to extend their existing management capabilities such as security services, firewalls, and intrusion detection systems to include their AWS resources. Amazon VPC integrates today with Amazon EC2, and will integrate with other AWS services in the future."

VPC definitions and terminology aside the new service is important for a few reasons.

1. In a sense Amazon now has publicly admitted that private clouds do exist and the core differentiation is isolation (what I call quarantined cloud infrastructure), be it virtual or physical.

2. Greater Hybrid Cloud Interoperability & Standardized Network Security by enabling native VPN capabilities within their cloud infrastructure and command line tools. Amazon's VPC has added a much greater ability to interoperate with existing "standardized" VPN implementations including:

  • Ability to establish IKE Security Association using Pre-Shared Keys (RFC 2409).
  • Ability to establish IPSec Security Associations in Tunnel mode (RFC 4301).
  • Ability to utilize the AES 128-bit encryption function (RFC 3602).
  • Ability to utilize the SHA-1 hashing function (RFC 2404).
  • Ability to utilize Diffie-Hellman Perfect Forward Secrecy in “Group 2” mode (RFC 2409).
  • Ability to establish Border Gateway Protocol (BGP) peerings (RFC 4271).
  • Ability to utilize IPSec Dead Peer Detection (RFC 3706).
  • Ability to adjust the Maximum Segment Size of TCP packets entering the VPN tunnel (RFC 4459).
  • Ability to reset the “Don’t Fragment” flag on packets (RFC 791).
  • Ability to fragment IP packets prior to encryption (RFC 4459).
  • (Amazon also plans to support Software VPNs in the near future.)

3. Further proof that Amazon is without any doubt going after the enterprise computing market where a VPN capability is arguably one of the most requested features.

4. Lastly greater network partitioning, using Amazon's VPC, your EC2 instances are on your network. They can access or be accessed by other systems on the network as if they were local. As far as you are concerned, the EC2 instances are additional local network resources -- there is no NAT translation. A seemless bridge to the cloud.

In the blog post announcing the new service, I found their hybrid cloud use case particularly interesting; "Imagine the many ways that you can now combine your existing on-premise static resources with dynamic resources from the Amazon VPC. You can expand your corporate network on a permanent or temporary basis. You can get resources for short-term experiments and then leave the instances running if the experiment succeeds. You can establish instances for use as part of a DR (Disaster Recovery) effort. You can even test new applications, systems, and middleware components without disturbing your existing versions."

This was exactly the vision I outlined in my original post describing the VPC concept. I envisioned a VPC in which you are given the ability to virtualize the network giving it particular characteristics & appearance that match the demands as well as requirements of a given application deployed in the cloud regardless of whether it's local or remote. Amazon seems to realize that cloud computing isn't a big switch to cloud computing where suddenly you stop using existing "private" data centers. But instead the true opportunity for enterprise customers is a hybrid model where you use the cloud as needed, when needed, and if needed and not a second longer then needed.

I also can't help wondering how other cloud centric VPN providers such as CohesiveFT will respond to the rather sudden addition of VPN functionality, which in a single move makes third party VPN software obsolete or at very least not nearly as useful. (I feel your pain, remember ElasticDrive?) I am also curious to see how other IaaS providers such as Rackspace respond to the move, it may or may not be in their interest to offer compatible VPC services that allow for a secure interface between cloud service providers. The jury's still out on this one.

Let me also point out that although Amazon's new VPC service does greatly improve network security, it is not a silver bullet and the same core risks in the use of virtualization still remain. If Amazon's hypervisor is exploited, you'd never know it and unless your data never leaves an encrypted state it's at risk at one end point or another.

At Enomaly we have also been working on enhanced VPC functionality for our cloud service provider customers around the globe. For me this move by Amazon is a great endorsement of an idea we as well as others have been pushing for quite awhile.

On a side note, before you ask, Yes, I'm just glad I bought the VirtualPrivateCloud.com./.net/.org domain names when I wrote the original post. And yes, a place holder site and announcement is coming soon ;)
