Public Clouds and the Latency Challenge

Last week, Patrick Thibodeau from Computerworld published a very interesting article: ‘Cross-ocean clouds gain despite millisecond delays’. When talking about issues that CIO’s have about moving applications to the cloud, writers address the obvious pitfalls – security, control, privacy and legal concerns. Rarely does one find someone acknowledging other, more subtle issues with deploying applications in the cloud, such as latency and usability across the world.

The problem – Private and Public Clouds

With an increase in server consolidation and centralization, one trend is to move more and more equipment to a central datacenter and setup a private cloud. The second is to do away with hardware altogether and go with a public cloud provider with applications now accessed over the internet. The result of both these approaches is an increase in latency experienced by users sitting in remote enterprise branch locations. While usually ignored during planning stages, latency and poor response times can make the difference between a successful implementation and an abandoned cloud migration project!

The Solution

  1. Private Clouds

The Solution for private clouds is simpler and has been available for a while now. The WAN Optimization industry evolved to solve this very problem. With the ability to control both ends of the link, everything from traditional box appliance implementations to the latest Aryaka WAN Optimization as a service platform can be used to mitigate the effects of latency and accelerate applications while saving bandwidth and improving application performance and user response times.

2. Public Clouds

As covered in the article, the challenge with public cloud-based implementations has been the fact that most current cloud-hosting datacenters are located in the US. When accessed from remote enterprise branch locations, latency over the internet is a constant challenge. Aryaka, we have a solution. Enterprises can either use Aryaka’s WAN Optimization as a service platform to backhaul and accelerate traffic to US headquarter locations and then access the internet. This model is often used by existing vendors as well.

The second, more interesting model is to think of the global Aryaka network as an internet traffic accelerator. Enterprise internet traffic can be accelerated over a dedicated/optimized network with other WAN traffic and routed to the internet from an Aryaka POP located in the vicinity of the public cloud provider’s datacenter.

Aryaka provides an integrated solution to all application performance issues, whether you are hosting applications in your very own private cloud, or using the public cloud!
