Does Cloud computing scares you?

For what specific usage cases is edge computing or fog computing a better choice than cloud computing?

  • Answer:

    Cloud computing is a super-set of edge computing.  Cloud computing involves renting computing resources from a provider.  The provider may operate one or more data centers.  Edge computing is the same, except it implies you are renting resources at many different global locations in order to be physically close to customers (the edge).  This results in minimal network latency. Fog computing appears to be a marketing term invented by Cisco which is equivalent to edge computing.  Here's the full definition as written by a Cisco rep. Quoted from http://www.cisco.com/web/about/ac50/ac207/crc_new/university/RFP/rfp13078.html (By Dan D.): Fog Computing is a paradigm that extends Cloud computing and services  to the edge of the network. Similar to Cloud, Fog provides data,  compute, storage, and application services to end-users. The  distinguishing Fog characteristics are its proximity to end-users, its  dense geographical distribution, and its support for mobility. Services  are hosted at the network edge or even end devices such as set-top-boxes  or access points. By doing so, Fog reduces service latency, and  improves QoS, resulting in superior user-experience. Fog Computing  supports emerging Internet of Everything (IoE) applications that demand  real-time/predictable latency (industrial automation, transportation,  networks of sensors and actuators). Thanks to its wide geographical  distribution the Fog paradigm is well positioned for real time big data  and real time analytics. Fog supports densely distributed data  collection points, hence adding a fourth axis to the often mentioned Big  Data dimensions (volume, variety, and velocity). Unlike traditional data centers, Fog devices are geographically  distributed over heterogeneous platforms, spanning multiple management  domains. Cisco is interested in innovative proposals that facilitate  service mobility across platforms, and technologies that preserve  end-user and content security and privacy across domains. Fog provides unique advantages for services across several verticals  such as IT, entertainment, advertising, personal computing etc. Cisco is  specially interested in proposals that focus on Fog Computing scenarios  related to Internet of Everything (IoE), Sensor Networks, Data  Analytics and other data intensive services to demonstrate the  advantages of such a new paradigm, to evaluate the trade-offs in both  experimental and production deployments and to address potential  research problems for those deployments.

In many cases , edge computing is a better choice than cloud computing.Company A deploy their fire alarm system on the Amazon Cloud in US virginia. And company A sells their fire alarm sensors all over the world. All the sensors collect the data and upload to the servers to calculate the possibility of a fire.Though their service is deployed on the cloud , it still have the single point problem.So the sensors in Asia send the data in high latency back to the servers.In the real world one or two second delay can make a huge difference.So distribution computing based on geo is needed for the real world.That make edge computing better than cloud computing.Our company already put edge computing into reality in China. And expanding global in 2016
