SDN seems to be rulling the datacenters..looking forward to hear about differences between Google and FB...I would think they would be aligned not clash, all they care from a hardware perspetive is cost...Kris

@Rick:  seems like a possible error in this phrase, mentions both low energy cost and high energy cost at the same time:

 "silicon photonic interconnects can sustain very high loads (over 100 Tb/s) with low energy costs (< 1 pJ/bit)...[but may] come at a relatively high energy cost."

@kris:  IIRC, Facebook started the Open Compute Project, and Google decided to roll their own version with the Google Platform, so it doesn't surprise me these two giants go similar-but-unique with networking approaches, too.  Also, some of the big Chinese datacenter outfits are coming up with their own versions.  Part of that is probably not-invented-here thinking, but all these big orgs have many experts that define and redefine their applications' needs continually.  I've seen some things indicating they are developing similar-but-unique architectures for storage, from RAM to flash to spinning/streaming media.

From a vendor standpoint that boils down to "give them what they want".  But the larger and potentially larger (more lucrative?) market will be in adapting the high-end items developed for these customers to serve the midrange customers--who can't usually afford a cadre of system architects.

thank you @markwrob for the explanation...somewhat puzzling strategy though...I thought the whole point of SDN was to be open and common to all datacenters by removing Cisco proprietary stuff...so the cost can come down significantly...but it seems we are replacing Cisco, Junniper, Huwaei with Google, FB and Alibaba...the more things change the more they stay the same

Its good for the industry that two giant users of web Google and Facebook are sharing their thoughts. It will benefit everytone. But both of them must have different needs how to use web content. Quanity of data must be comparable but privacy sectors are different.

You are right, if the Giants like Google, Facebook are designing and developing their own systems, there can hardly any chance of being compatible to each other. It will be proprietary and will remain proprietary.

@Kinnar: I think its TBD whether Google and Facebook networking platfroms will be compatible.

Interestingly, Google is helping drive Openflow but Facebook is driving networking through its Open Compute Project.

Is there any requirement for the data centre design of different companies need the compatibility when it is one of their secret sauce to provide the light speed access to the user.

@Kinnar: Well if there are common standards these giants will be developing by, then one can expect to see both of these companies working in unison under a common architecture than supports both architectures. We just have to wait and see.

@markwrob: In the end they are building to serve the customers, and I?d like to see the beta testing of such architectures and how the common crowd adapts to the architecture faster. The faster you habituate yourself to any of the architectures, the more are you going to use it, and this will dictate market holdings of both the companies.

This area is going to build strenghts due to the growing need of the datacenters. Lots of research ongoing to integrate the photonics onto the silicon chip.

LATEST ARCHIVED BROADCAST

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
