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
Craig Labovitz writes to report: At 18:40 UTC Amazon Web Services suffered performance issues for their North Virginia datacenter. The performance issues impacted services such as EC2, S3, SES, RDS, and Mechanical Turk among others. more
2013 may be a promising year for global trade in technology with the kick-off of the International Technology Agreement expansion discussions, the Trans-Atlantic Trade and Investment Partnership, and as the Trade in Services Agreement gets going. But China calls its own tune, and is now threatening to restrict its market for Internet-enabled technologies through a clever device that could cost its trading partners billions. more
Several developments are coming together in cloud computing that are creating shockwaves throughout society and in the economy. Over the last five years we have seen the debate about cloud computing hotting up. There was the hype around the new development at the same time as warnings regarding security and privacy, and for a while the market seemed subdued about the new development. However the economic reality of cloud computing meant that enterprises and government bureaucracies had little choice but to move ahead with cloud computing... more
This is a topic that we have discussed on several occasions over the last decade, but it now seems as though things are slowly moving forward. A new company, Intabank, has set up a service whereby its enterprise customers can pool bandwidth that the intermediate company can then use to sell to other customers; enabling organisations to monetise their network connectivity assets. more
Netflix is arguable one of the world's biggest users of cloud computing, renting all its computing power from Amazon Web Services, the cloud division of Amazon.com, which runs its own video-streaming service that competes with Netflix. Ashlee Vance from Bloomberg reports. more
