Stress free Cloud

In Sizing the Cloud; Understanding the Opportunities in Cloud Services (published in March 2009) analysts at Gartner, Inc. predict a global market for enterprise cloud services reaching $150.1 billion in 2013 – more than three times the size of today’s market of $46.4 billion. The cloud-based enterprise will be dependent on the internet to an extent way beyond the situation today, and information systems and applications will be utility services, like water or electricity — a click of the mouse to bring up the CRM software and shut it down, with the user paying for a metered service.

As far as I’m concerned this is a fantastic development which will allow businesses to focus on — well, what they do best, where they can add value. Information resources will be available on demand, like tapwater. Except that a packet of data is not like a drop of water; those data packets may be carrying business-critical data. The internet is a two-sided coin for the enterprise: one the one hand, on-demand access to flexible, massively scalable information resources ranging from basic hardware platforms to individualized services and applications software; on the other hand, the vector for increasingly intense efforts to penetrate enterprise information systems for criminal gain. In other words, the enterprise is in the process of migrating it’s information resources to the most stressful environment you can think of if you’ve ever had to think about information security.

If the Cloud Computing paradigm is to fulfill its promises, we urgently need to find ways of reducing the stress of internet dependency. We need to protect ourselves from the internet that threatens us, to get the full benefits of the internet that will make our business more agile, more responsive, which will allow us to evolve and progress. If we can’t make the internet “stress free” we’ll start seeing the (costly) development of parallel secure networks for enterprise applications.

If the best way to avoid internet attacks is not to connect to the internet, that’s clearly an unrealistic approach today. What we can do, however, is to segment different usages, isolating access to sensitive, business-critical data and applications from the potential threats. While building an entirely new network is probably a stretch too far, a more realistic solution, perfectly feasible today, is to isolate individual web applications by virtualizing access at the source, the browser itself. Enterprise end-users access sensitive business applications and data over the internet using secure tunnels carrying virtualized browser sessions. With the virtual browsers hosted in close proximity to the applications, data need never be exposed on the internet with this architecture. We can’t clean up the internet to make it entirely safe for your business critical data and applications, but by ensuring that critical systems and end-user browser sessions are protected from attack we can bring a “stress-free” internet experience several steps closer for the CIO.
