How Cloud Computing is Forcing Us to Rethink Data Security

Traditional IT security models focus on building a secure perimeter around corporate infrastructure. This is akin to the classic fortress mentality of putting up walls and surrounding those walls with additional defenses. If anything gets inside the walls, all bets are off. HP Enterprise & Cloud Security Strategist, Rafal Los, argues that this model is flawed and should be changed with or without cloud computing. Cloud computing amplifies the issue, because the concept of boundraies has changed, necessitating the switch to role-based security. One key area where this change needs to happen is in rethinking application development with a focus on authorization to access data, rather than simply authenticating access to data. LockerGnome’s Jake Ludington has an interesting coversation with Rafal about cloud security, what’s the same, what’s different, and what some best practice scenarios involve in planning for security in the cloud.

www.cisco.com An animation telling the story of datacenter traffic growth, through the scope of the back office of a cupcake bakery. Transcript: How big will cloud computing be in 2015? Consider the cupcake. When you interact with a business — such as a bakery — your request is sent to a datacenter. The order entry datacenter stores your information, authenticates it, and synchronizes it with other systems. For many businesses, this internal processing can generate as much as 80% of the datacenter traffic. From there, another 15% of your baker’s datacenter traffic comes from sending the order to the factory datacenter where it’s put into production. Finally, the last 5% of traffic is generated by the confirmation notice of your cupcake order. So while you don’t see it, the total traffic generated from a single order can multiply exponentially, and that can be a challenge for businesses and service providers to handle. This global datacenter traffic reached 1.1 zettabytes in 2010, and will grow more than four-fold to 4.8 zettabytes by 2015. Of that, Cloud traffic is growing two-times faster than traditional data center traffic. While in 2010, only 21% of workloads were processed through the cloud, by 2015, that figure will jump to 57%. More workloads moving to the cloud means less complexity in the datacenter, improved economies of scale, and most importantly, more cupcakes.
