Plexxi recently teamed up with Colovore, Piston Cloud Computing and King Star Computers to publish a whitepaper that challenges the assumption that the public cloud is inherently cheaper than the private cloud. Though the rapid speed of deployment and reduced capital expenditure has made services such as Amazon EC2 very attractive, the study shows that the rate of cost increase is often higher than that of a self-hosted private cloud solution. Brandon Butler recently reported on the paper’s findings for Network World. We hope you were able to tune into DemoFriday today on SDNCentral. Our own Ed Henry and Nils Stewart did an excellent job of explaining how to construct Big Data fabrics that easily integrate with systems like OpenStack and Cloudera. We’ll share the full webinar once it’s live on SDNCentral’s site. In this week’s PlexxiTube of the week, Dan Backman exp... (more)

What Is Important for #Cloud Services? | @CloudExpo

Amazon is indisputably the biggest name in cloud service providers. They have built up a strong market presence primarily on the argument that access to cheap compute and storage resources is attractive to companies looking to shed IT costs as they move from on-premises solutions to the cloud. But after the initial push for cheap resources, how will this market develop? Is cheap really cheap? Amazon has cut prices to their cloud offering more than 40 times since introducing the service in 2006. The way this gets translated in press circles is that cloud services pricing is approa...

Datacenter resource fragmentation

The concept of resource fragmentation is common in the IT world. In the simplest of contexts, resource fragmentation occurs when blocks of capacity (compute, storage, whatever) are allocated, freed, and ultimately re-allocated to create noncontiguous blocks. While the most familiar setting for fragmentation is memory allocation, the phenomenon plays itself out within the datacenter as well. But what does resource fragmentation look like in the datacenter? And more importantly, what is the remediation? The impacts of virtualization Server virtualization does for applications and c...

@Cloud Expo | Cracking the #Cloud Code

The cloud is one of those technology trends that seems to be perpetually on the cusp of becoming ubiquitous. But if recent analyst reports are any indication, cloud’s breakthrough moment is imminent. Late last year, Gartner predicted that in 2016, the bulk of new IT spend would shift to the public cloud, and that by the end of 2017, nearly half of all enterprises will have hybrid cloud deployments. But if cloud has been around for so long, why will it take so long for cloud to become the dominant source of IT spend? Psychology vs Technology The determinant for most change is the... (more)

Why Contextual Data Locality Matters

Big Data is quickly overtaking SDN as a key phrase in today’s networking lingo. And overused already as it may be, it actually has a lot more meaning and definition compared to SDN. Big Data solutions are designed to work on lots of data as the name suggests. Of course they have been around forever, talk to any large bank, credit card company, airline or logistics company and all of them have had applications running on extremely large databases and data sets forever. But this is the new Big Data, the one inspired by Hadoop, MapReduce and friends. High performance compute cluster... (more)
