Technical Article Square Infrastructure Pegs Don’t Fit in Round Network Holes March 01, 2010 by Lori MacVittie 3341 article application delivery architecture availability cloud design infrastructure load balancing management performance scalability us virtual network appliance virtualization vna 0 Ultimately a highly-scalable, high-performance architecture will rely on choosing the right form factor in the right places at the right time. Scale is not just about servers, and for corporate data centers and cloud computing providers looking to realize the benefits of rapid elasticity and on-demand provisioning scale simply must be one of the foundational premises upon which a dynamic data center is built. And that includes the infrastructure. This isn’t the first time I’ve touched upon this subject, but it’s a concept that needs to be reiterated – especially with so many pundits and analysts looking for the next big virtualization wave to crash onto the infrastructure beachhead. I’m here to tell you, though, that the devil is in the details. Virtual network appliances (VNAs) are certainly one means to achieving elastic scalability of infrastructure services but just as scale is not just about servers it’s also not just about form factor. It’s about the right form factor in the right place and, ultimately, at the right time. last modified: March 01, 2010 0 Comment(s): You must be logged in to post comments.
