Cloud Computing Types: Public Cloud, Hybrid Cloud, Private Cloud

It's no secret that I don't very much like this whole private cloud or internal cloud concept... on the basis that while advanced virtualisation technologies are valuable to businesses they are a severe short sell of what cloud computing is ultimately capable of. The electricity grid took over from the on-site generators very quickly and I expect cloud computing to do the same with respect to private servers, racks and datacenters... more

Shedding Light on How Much Energy the Internet and ICTs Consume

Ever since I published an essay exploring the relationship between climate change and the Internet, I have endeavored to bring this subject to the fore as often as possible (and in relevant fora and discussions) since the responsibility of creating a more sustainable world falls on all communities and stakeholder groups. It is particularly pressing now -- at a time when international interest in curbing climate change is strengthening, while it is juxtaposed with the receding commitments of the United States government... more

Network Solutions Under Large Scale DDoS Attack, Millions of Websites Potentially Unreachable

Network Solutions is having problems with "all" its name servers, according to their tech support and a recent post on North American Network Operators' Group (NANOG) mailing list indicates that it has been under very large-scale UDP/53 DDoS attack for the last 48 hour period. As a result, domain names hosted with Network Solutions' Worldnic have been affected. Network Solutions is one of the leading domain registrars and DNS hosting providers in the world, managing more than 7.6 million domain names. more

Business Model Canvas for SaaS Providers

As a follow up to the earlier article on the IaaS business model, here is a high level overview of the SaaS provider business model and some of the strategic options that are in there... As examples in this article I consider two hypothetical SaaS providers. The first one delivers bookkeeping software, the second one delivers a project collaboration platform. more

Cloud Computing and Privacy

There has been a good deal of talk of late on the important topic of security and privacy in relation to cloud computing. Indeed there are some legitimate concerns and some work that needs to be done in this area in general, but I'm going to focus today on the latter term (indeed they are distinct -- as a CISSP security is my forte but I will talk more on this separately). more

An Interview With Richard Whitt, Google’s Washington Telecom and Media Counsel

I recently had the opportunity to interview, Richard Whitt, Google's Washington Telecom and Media Counsel, who will be one of the keynote speakers at the upcoming Emerging Communications Conference (eComm 2009) being held on March 3-5 at the San Francisco Airport Marriott. The following is the transcript of our phone conversation and the audio recording of the interview. more

Google DNS to Be Discontinued in Brazil Ahead of New Law

Doug Madory from Renesys reports: "In response to recent NSA spying allegations, Brazil is pressing ahead with a new law to require Internet companies like Google to store data about Brazilian users inside Brazil, where it will be subject to local privacy laws. The proposed legislation could be signed into law as early as the end of this week. However, Google's DNS service started leaving the country on September 12th, the day President Rousseff announced her intention to require local storage of user data." more

Are Blockchains the Most Expensive Database Ever Invented?

One of the oft-made claims about Bitcoin and its blockchain transaction ledger is that they make transactions really cheap, so you can pay someone anywhere in the world for free, or close to it. But when you look closer, is that really true? Not by a long shot. Bitcoin transactions are stored in a large shared database called the blockchain. more

The Internet is Dead - Long Live the Internet

Back in the early 2000s, several notable Internet researchers were predicting the death of the Internet. Based on the narrative, the Internet infrastructure had not been designed for the scale that was being projected at the time, supposedly leading to fatal security and scalability issues. Yet somehow the Internet industry has always found a way to dodge the bullet at the very last minute. more

Designing Secure Networks with Cisco Technology, Part 4

In this multipart series I will be presenting some of the leading industry-standard best practices for enterprise network security using Cisco technologies... In Part 3 of this series I began to discuss Cisco technologies as a standard for enterprise data security. In this article we take a look at how Cisco firewall and packet filtering technologies can be used at the network perimeter to enhance enterprise security. more

IoT Devices Will Never Be Secure - Enter the Programmable Networks

Harvard Business Review just ran an interesting article on the information security aspects of Internet of Things (IoT). Based on the storyline, the smart city initiatives are doomed to fail unless the security of the IoT devices and the systems will be improved. While security of the digital society is obviously a key concern, I am not entirely convinced that relying on the security of individual devices and systems is the best course of action. more

SEC Filing Reveals Facebook Network Equipment Valued Over $1B at Close of 2011

"Facebook reported in its SEC filing that it owns 'network equipment' valued at $1.016 billion at the close of 2011," reports Rich Miller of Data Center Knowledge. "The number reflects the expense of rapidly building a massive Internet infrastructure, including Facebook's shift from buying vendor gear and leasing data centers to building its own servers, racks and custom data centers." more

Let’s Not Forget About Solar Flares

As the world becomes more and more reliant on electronics, it's worth a periodic reminder that a large solar flare could knock out much of the electronics on earth. Such an event would be devastating to the Internet, satellite broadband, and the many electronics we use in daily life. A solar flare is the result of periodic ejections of matter from the sun into space. Scientists still aren't entirely sure what causes solar flares, but they know that it's somehow related to shifts in the sun's magnetic field. more
