I am a greentech enthusiast and I have been closely following the greentech VC investment landscape. The VCs like Kleiner Perkins who have had a large greentech portfolio including companies such as Bloom Energy are scaling down on greentech investment . Their current investment is not likely to get any returns close to what a VC would expect. The fundamental challenge with such greentech (excluding software) investment is that they are open ended capital-intensive; you just don't know home much time it would take to build the technology/product, how much it would cost, and how much you would be able to sell it for. The market fluctuations make things even worse. This is not only true in the case of start-ups but also true for the large companies; Applied Materials' grand plan to revolutionize thin-film solar business ended up in a bust .   There's a different way to approach this monumental challenge. Just look at how open source has evolved. It started out as non-commerc...

Today, Cloudera announced a new $40m funding round to scale their sales and marketing efforts and a partnership with NetApp where NetApp will resell Cloudera's Hadoop as part of their solution portfolio. These both announcements are critical to where the cloud and Big Data are headed. Big Data going mainstream: Hadoop and MapReduce are not only meant for Google, Yahoo, and fancy Silicon Valley start-ups. People have recognized that there's a wider market for Hadoop for consumer as well as enterprise software applications. As I have argued before Hadoop and Cloud is a match made in heaven. I blogged about Cloudera and the rising demand of data-centric massive parallel processing almost 2.5 years back, Obviously, we have come a long way. The latest Hadoop conference is completely sold out. It's good to see the early signs of Hadoop going mainstream. I am expecting to see similar success for companies such as Datastax (previously Riptano) which is a "Cloudera for Cass...

Recently Google published the Power Usage Efficiency (PUE) numbers of their data centers. PUE is defined as a ratio of the total power consumed by a data center to the power consumed by the IT equipments of the facility. Google's data centers' PUE ranges from 1.1 to 1.3 which is quite impressive. Though it is unclear why all the data centers have slightly different PUE. Are they designed differently or are they all not tuned to improve for the energy efficiency? In any case I am glad to see that Google is committed to the Green Grid initiative and is making the measurement data and method publicly available. This should encourage other organizations to improve the energy performance of their data centers. The energy efficiency of a data center can be classified into three main categories: 1. Efficiency of the facility: The PUE is designed to measure this kind of efficiency that is based on how a facility that hosts a data center is designed such as its physical location, la...
