China's notoriously high air pollution levels are a well-documented public-health issue. But pollution also has other less talked about effects. One of them is on the efficiency of data centers in the country. more
Cloud or dedicated? That's the question companies face each time they need new storage space or resources -- is it better to build local or host off site? Both tech segments are performing strongly, with the global data center blade server market to reach more than $15 billion by 2019 at a compound annual growth rate of 10.25 percent and cloud computing sitting on a $16 billion market that's only trending up thanks to increased public and hybrid adoption. In other words, it's virtual war: Who wins the battle? more
As Internet connection continues on a steady path of becoming a ubiquitous commodity in mature markets, we saw an eruption of big data tracking and analysis software in 2014. But what are operators going to do with all this new information? And how can they turn data into revenue? To start with, providers need more than just a data measurement tool. They need a solution that can analyze real-time data and then automate processes to optimize their networks and improve their subscribers' experiences. more
Last June I wrote an article titled "The IETF's Other Diversity Challenge" where I discussed the positive steps the Internet Engineering Task Force (IETF) is taking to increase the diversity of its participants and raised a potentially overlooked demographic: Network Operators. That essay was a problem statement of sorts, and I was long ago taught that you should only raise problems that you have a solution for, or are at least willing to help solve. more
Every year those in the security industry are bombarded with various cyber security predictions. There's the good, the bad and the ugly. Some predictions are fairly ground breaking, while others are just recycled from previous years -- that's allowed of course if the threats still stand. In part one of my predictions I looked at the malware threats, so let's take a look at big data and the cloud for part two. more
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
The Internet Society (ISOC) has been working with the African Union (AU) to facilitate the African Internet Exchange System (AXIS). This AXIS project funded by the EU-Africa Infrastructure Trust Fund and the Government of Luxembourg will help keep Internet traffic in Africa internal to the continent and avoid expensive international transit costs and delay latency in routing Internet traffic through other continents. more
In Tony Li's article on path MTU discovery we see this text: "The next attempt to solve the MTU problem has been Packetization Layer Path MTU Discovery (PLPMTUD). Rather than depending on ICMP messaging, in this approach, the transport layer depends on packet loss to determine that the packet was too big for the network. Heuristics are used to differentiate between MTU problems and congestion. Obviously, this technique is only practical for protocols where the source can determine that there has been packet loss. Unidirectional, unacknowledged transfers, typically using UDP, would not be able to use this mechanism. To date, PLPMTUD hasn't demonstrated a significant improvement in the situation." Tony's article is (as usual) quite readable and useful, but my specific concern here is DNS... more
The Internet Engineering Task Force (IETF) is the standards body for the Internet. It is the organization that publishes and maintains the standards describing the Internet Protocol (IP -- versions 4 and 6), and all directly related and supporting protocols, such as TCP, UDP, DNS (and DNSSEC), BGP, DHCP, NDP, the list goes on, and on... But how do they do that? How does the IETF produce documents, and ensure that they are high quality, relevant, and influential? more
Lily Hay Newman reporting in Slate: "You may associate the sound of the Internet with the sound of a computer fan or the extinct song of dial-up. But the real sound of the information super highway is the whir of hard discs and fans spinning inside servers and creating a powerful white noise. It seems like it might be a soothing din, but workers report that it's a problem." more
Nowadays, everybody is talking about cloud computing. Fans say it's the future, the answer to every problem with computing as we know it; others say it's just a fad and will eventually die. Who's right? While nobody knows the future, the fact is, enough evidence is available that we can all reasonably predict what's coming. Consider these facts... more
Rich Miller reporting in Data Center Knowledge: "Google continues to pump big bucks into its data center operations, investing a massive $7.35 billion in capital expenditures in its Internet infrastructure during 2013. The spending is driven by a massive expansion of Google's global data center network, which represents perhaps the largest construction effort in the history of the data center industry." According to company's reported capital expenditure, total spending adds up to $7.35 billion - more than double the $3.27 billion in CapEx the company reported in 2012. more
BGP. Border Gateway Protocol. The de-facto standard routing protocol of the Internet. The nervous system of the Internet. I don't think I can overstate the importance, the criticality of BGP to the operation of the modern Internet. BGP is the glue that holds the Internet together at its core. And like so many integral pieces of the Internet, it, too, is designed and built on the principle of trust... The folks who operate the individual networks that make up the Internet are generally interested in keeping the Internet operating, in keeping the packets flowing. And they do a great job, for the most part. more
Jason Verge reporting in Data Center Knowledge: "Google's data center spending and investment continues to soar. The Internet giant announced a EUR450 million (which is about 608 million U.S. dollars) expansion at its Hamina data center in Finland. This comes in addition to an already announced EUR350 million (or about 473 million U.S. dollars) investment. Worldwide, the company recorded a whopping $2.29 billion (in U.S. dollars) in capital expenditures in the third quarter of 2013 alone, driven primarily by massive expansion projects." more
When I read government arguments in defense of the NSA, an oft-repeated line was: We're not targeting Americans. We're targeting foreigners. Foreigners. I really dislike that word. And I'm sure companies like Apple, Google and Facebook do as well. Why? more
