Cloud Is the New Mainframe

Cloud computing, from a business and management perspective, has a great deal in common with mainframe computing. Mainframes are powerful, expensive and centralized pieces of computing equipment. This is in line with their role as infrastructure for mission-critical applications. For these types of applications, mainframes can be fairly efficient, even though they tend to need large teams of support specialists... Cloud computing is a new style of computing... more»

IPv6 is Growing in Maturity, but Not Necessarily in Adoption

According to Google native IPv6 penetration has structurally crossed the 0.2% mark as a percentage of total traffic on the Internet in early 2011. This may not seem much, but it has doubled in a year, in an Internet that is still growing exponentially. more»

Google's Spending Spree: 2.4 Million Servers, and Counting

Google just published its Q3 financial results. So, what is Google spending on IT, and how much servers would that buy? This is one of their best kept secrets. In this post I give ballpark estimates based on back-of-the-envelop calculations, similar to the 'guestimates' I made 5 years ago. more»

An Attack on DNS is an Attack on the Internet

On Saturday Aug 7th, DNS provider DNS Made Easy was the target of a very large denial of service attack. As far as can be determined the total traffic volume exceeded 40 Gigabit/second, enough to saturate 1 million dialup Internet lines. Several of DNS Made Easy's upstream providers had saturated backbone links themselves. There are indications that not only DNS Made Easy suffered from this attack, but the Internet as a whole. more»

The Digital Divide on IP Addresses

This growth is clearly unsustainable within the IPv4 address space. Not every country can have these utilization levels. The hunger for new addresses is greatest in China (currently at 1 IPv4 address per 4 inhabitants) and India (1 address per 53 inhabitants). To put these at the modest level of 1 address per inhabitant requires more than 2.2 billion addresses, where there are currently only 290 million left... Given these numbers and the overall strong growth, any hopes of being able to reuse space that is allocated but not used (i.e. pre-CIDR) are futile. This demand dwarfs the entire US allocation. more»

Buying Open Source… It's a Different Ecosystem

A lot of organizations are interested in open source software, but fail to give it a fair chance compared to proprietary solutions. One reason for this is that the typical invitation to tender process puts open source at a disadvantage. Open source, as it happens, is made in a different ecosystem. more»

Infrastructures on the Next Web

Werner Vogels, CTO of Amazon, explains how web applications will be built in the future. His point is twofold. The bad news is that expectations for good web applications are sky high. It has to have rich media, available on multiple devices, very scalable, social networking and that is just the beginning. The good news is that a lot of this can be done by services that are readily available on the web, with reasonable usage based pricing. more»
