More than 50 percent of all workloads will be processed in the cloud by 2014.
This statement comes from a Cisco "Global Cloud" whitepaper, which examines the current state of things and guesses where we'll be at in 2015. It also forecasts a 22-percent compound annual growth rate (CAGR) for cloud datacenters, with the share of workloads handled by these centers rising from 21 percent back in 2010 to 57 percent by 2015. The report says that the workloads themselves will increase about 2.5 times in that period.
Cloud is of course the key to these additional workloads, as it shifts the paradigm from one workload to multiple workloads on any single server. The Cisco report also sees cloud-based traffic growing at a 33-percent CAGR in the 2010-2015, accounting for 34 percent of all datacenter traffic by 2015, as the total datacenter dataflow approaches 5 zettabytes annually worldwide.
A quick reminder shows that 5 zettabytes equals 5 billion terabytes. (I prefer to think of a zettabyte as a 1021 byte, as I quickly lose track of the names after "tera-".) Truly the era of Big Data is upon us.
Much of this will be driven by video, and especially video on mobile devices. The Cisco research implies this - although overall cloud-based datacenter traffic will be 34 percent in 2015, the consumer cloud will be 37-percent cloud-driven, compared to only 19 percent within the business cloud.
Getting out my old slide rule deduces that this means the consumer cloud will account for five-sixths of total datacenter traffic - about 83 percent of it.
ZOMFG. No wonder the paleolithic mandarins of the music and film industries want to cast sharing and everything else under the guise of stealing and terrorism.
The Cisco report also has a section devoted to Cloud Readiness. This is the same term used by AsiaCloud, which published a report on the topic last year, and which features Cisco's Singapore-based CTO Bernie Trudel as one of its leaders.
The Cisco report states that a location must have a download speed of greater than 2.5Mbps (and latency of less than 50ms) to handle advanced cloud applications. It defines the latter as advanced gaming, video chat, and file sharing; HD audio and video conferencing; and streaming of super HD video. It prescribes a modest download speed between 750kbps and 2.5Mbps for "intermediate" cloud apps, including telephony, basic chat and conferencing, and what it terms advanced social networking.
Seems modest enough. My recent research on bandwidth around the world, which used - as did the Cisco report - bandwidth speed data from Seattle-based Ookla, shows all of the world leaders with speeds many times that of Cisco's advanced requirement.
Even the laggards amongst today's dynamic, developing economies - such as such as India and the Philippines (both at 1.7Mbps), Indonesia (at 1.35Mbps), and Nigeria (at 880kbps) - meet the intermediate standard. Other developing hotspots such as Jordan (at 2.97Mbps), South Africa (at 3.02Mbps), and Kenya (at 3.31Mbps) are far above the advanced standard.
All this tells me that Cisco is on track with its projections. We'll be wallowing in zettabytes soon enough, and we'll have the capacity to do this. Now, if someone can help me figure out what this means for the hardware industry - chips, storage, and plumbing - I might get totally optimistic about the near future.

Sensors and effectors of IoT are solving problems in new ways, but small businesses have been slow to join the quantified world. They’ll need information from IoT using applications as varied as the businesses themselves. In his session at @ThingsExpo, Roger Meike, Distinguished Engineer, Director of Technology Innovation at Intuit, showed how IoT manufacturers can use open standards, public APIs and custom apps to enable the Quantified Small Business. He used a Raspberry Pi to connect sensors...

In most cases, it is convenient to have some human interaction with a web (micro-)service, no matter how small it is. A traditional approach would be to create an HTTP interface, where user requests will be dispatched and HTML/CSS pages must be served. This approach is indeed very traditional for a web site, but not really convenient for a web service, which is not intended to be good looking, 24x7 up and running and UX-optimized. Instead, talking to a web service in a chat-bot mode would be muc...

It's easy to assume that your app will run on a fast and reliable network. The reality for your app's users, though, is often a slow, unreliable network with spotty coverage. What happens when the network doesn't work, or when the device is in airplane mode? You get unhappy, frustrated users. An offline-first app is an app that works, without error, when there is no network connection.

Cognitive Computing is becoming the foundation for a new generation of solutions that have the potential to transform business. Unlike traditional approaches to building solutions, a cognitive computing approach allows the data to help determine the way applications are designed. This contrasts with conventional software development that begins with defining logic based on the current way a business operates. In her session at 18th Cloud Expo, Judith S. Hurwitz, President and CEO of Hurwitz & ...

More and more companies are looking to microservices as an architectural pattern for breaking apart applications into more manageable pieces so that agile teams can deliver new features quicker and more effectively. What this pattern has done more than anything to date is spark organizational transformations, setting the foundation for future application development. In practice, however, there are a number of considerations to make that go beyond simply “build, ship, and run,” which changes ho...
