- Performance. Irrespective of the type of service deployed, all cloud computing initiatives have one thing in common – data is centralized, while users are distributed. This places an increased emphasis on the network, making cloud computing susceptible to the same WAN bandwidth, latency, and quality challenges that impact other enterprise applications. By overcoming these challenges, WAN optimization is critical to all cloud computing initiatives.

- Fault tolerance. Enterprises spend a lot of time and money building redundancy into their networks to ensure that if anything from a single server all the way to an entire data center goes down, there is adequate connectivity to backup resources. In the case of cloud, the same fault tolerance is needed – only an order of magnitude higher. What can be done? Here are some things to look for when implementing high capacity off-site data protection.
- Mobility. Given the recent Amazon issues, many enterprises might think twice about putting all their eggs in one basket, requiring data to be replicated between clouds and accessed across multiple clouds. There are many facets to ensuring this happens successfully. All I can say on this topic is stay tuned, as it is about to heat up.
By now, enough pundits have weighed in on Amazon’s cloud woes that I am not going to pile onto the fray. But, I do think there is an interesting side topic here pertaining to cloud services that is worth exploring – the cloud itself. Take two minutes to tell us what you think about the cloud and its ability to support strategic services, and you will be entered to win one of five iPad 2s.
Silver Peak has been working with various enterprises as they deploy different cloud services, from Google apps to hosted Microsoft Exchange services to cloud disaster recovery. In all these instances, the same lesson rings true – the “cloud” is a large network, upon which application, platforms, and other services are hosted and delivered. Whether that network is the public Internet or a service provider’s infrastructure, the cloud itself is subject to the same issues as any other large, geographically distributed wide area network (WAN). For example:
