In the cloud, distance matters
Here is Eric Wolford talking to me about cloud performance at the Riverbed offices in San Francisco.
The cloud is typically presented as an amorphous blob, a non-physical space where its real world elements (servers and routers) become intangibles. Data comes in, data flows out.
But for the companies building the clouds – the service providers and hardware vendors – what happens to the data inside the blob is of vital importance. More and more applications are being crammed into data centers and the physical distance between users and their applications is growing.
The problem, according to Eric Wolford, executive vice president at Riverbed, is “physics doesn’t change regardless of business model,” meaning the moving to private networks to cloud computing still has the same application challenges as before. The longer the distance and more hops that a packet must take, there is a higher chance the packet will be delayed, lost or arrive out of sequence. The impact on users is hanging applications and timeouts.
By using application acceleration, cloud providers can mitigate these problems so performance inside the cloud is not affected by competing applications. In fact, it allows service providers to offer a cloud-to-desktop performance guarantee.
