Google’s Solution to Unify Their Databases {4}

by Brian B
The article I chose this week is named “Google Spans Entire Planet With GPS-Powered Database” by Cade Metz. The article starts off by talking about a Google Engineer named Vijay Gill while he was at a conference. The question he was posed was how he would change how “Google’s datacenters if he had a magic wand (Metz, 2012).” His answer was “he would use that magic wand to build a single system that could automatically and instantly juggle information across all of Google’s data centers (Metz, 2012).” The interesting part of this article is that Google has done just that. The solution that he had in his answer is called Spanner. Spanner is a system that lets Google “juggle data across as many as 10 million servers sitting in “hundreds to thousands” of data centers across the globe (Metz, 2012).” The power of Spanner is that it lets many people handle the data around the world, while “all users see the same collection of information at all times (Metz, 2012).” Spanner accomplishes this task with its TrueTime API. Along with this API Google has also gone to the trouble of setting up master servers with built-in atomic clocks coupled with GPS to ensure accurate server times. This allows the entire network to stay roughly synched up with all of the different parts of Google’s data infrastructure. The article goes on to say that usually companies will just use a third party as their clock instead of installing their own.  It ends on the fact that this kind of approach would be cost too much for most companies to implement, but that Google tends to be ahead of the curve. read more...

Updating an IT Professional {4}

by Miguel V
With technology trends like cloud computing, big data and converged infrastructures “significantly changing the way enterprise IT professionals run their data centers” Cisco Systems is teaming up with EMC and VMware to provide IT professionals training “in a wide range of areas impacting the data center, from networking and cloud computing to storage and virtualization.” Cisco goals are to give IT administrators the required training to address technology trend issues. With this program Cisco and its partners are leading the way in transforming skills for the next generation of IT professionals . With cloud computing changing the way information and data  is being sent from one server to the next “IT organizations must cultivate new cloud architecture skills, understand how to use big data and maintain deep domain expertise with a renewed understanding of virtualization and technology convergence.” Through its training courses Cisco plans on giving technical “professionals the skills to build and run these evolving data centers” by providing ” a prescriptive and simple way to acquire the right skills at the right time.
This article has a couple of topics that relate to what we discussed about in class when dealing with data modeling and the importance of knowing good naming techniques that everyone can understand. Personally I like that Cisco Systems is stepping up and providing IT professionals that don’t want to go back to college a simple course that is design to update them on the new technology and practices of an IT professional in a simple and easy to understand way. read more...

Changing The IT Playing Field {1}

by Anthony T
Interestingly enough construction companies are seeing and contributing to the change in the field of IT. Data centers being built today, according to Mortensen Construction executives, are at a much larger scale than they once were. One particular data center worth mentioning is the Switch which boasts 400,000 square ft. It’s size allows many different cloud providers to run their operations inside this enormous data center. Software development companies, such as Smith Electrical Vehicles, which process large amounts of data are becoming aware of the computer capacity of the new age data centers. Traditional IT infrastructures can no longer handle the needs of companies like Smith Electrical Vehicles which is why data centers like the Switch are becoming more and more popular. This trend of large scale data centers is directly related to the growing needs of enterprises in terms of computing.
A common topic both in this article and in this weeks lecture was database schema. The article mentions that companies have had to design their schema by means of schema redesign and sharding to enhance application performance. The concept of sharding really grabbed my attention. Turns out this concept refers to process in which you can break your database down into small pieces and then send it to multiple servers.
Having read this article I now understand one of the major trends that is happening in the field of Information Technology. As an IT undergrad I feel that articles like this one are very useful in helping students like myself understand that in order to be successful in this field we must also be aware of how the industry is shifting away from traditional corporate environments. read more...

Cisco Wants To Light Up Data Centers {1}

by Toan T
The article that I read talks about how Cisco is planning to purchase Lightwire, a new company that makes optical technology for high-speed networking similar to fiber optics. The deal will cost $271 million for Cisco. Good thing is expected from Lightwire as Cisco believes that the small high-speed silicon chips that Lightwire uses to transmit data via pulses of light instead of electric signals will come in useful. Cisco wants to bring optical networking technologies into data centers by creating high-speed yet affordable switches. With fast data centers, they can allow the end users can access and retrieve large data sets. read more...
