TechEd 2013 - Day 4

Last day of TechEd 2013 ended, goodbye Spain. This day ended with a lot of interesting sessions related to Windows 8, Azure and Big data. I discover new ways how we can use Bitlocker for enterprise customers and why different 3rd party prefer to use Bitlocker and give up of their own mechanism.
I think that you heard that the preview version of Windows 8.1 can be downloaded from Microsoft news. Be aware, if you install the preview version of Windows 8.1, moving to the final version of 8.1 will not be so easily. When you go to the preview version, don’t let the installer to update the backup partition also. In this way it will be very easily to go back to 8.0 and install the final version of Windows 8.1. In general I prefer to use install the preview version of any software o virtual machines.
While attending to a session about big data and Hadoop I find out how you can increase the performance of a reduce operation. During the reduce operation it is recommended to have as few as possible. Even if the size of the files is big, it is not important. Having only a few number of files at this step will make the reduce operation faster.
“ASVMITI” is the storage mechanism offered by Microsoft. One of the benefits of this storage is the persistence. The SLA that is offered to the clients will offer us the data persistence and access of all information, even if we will stop or delete our HD. This is great, because after the process of data ends, we will be able to access all this data. Don’t forget that storing data into cloud is very cheap. As input, we can use any kind of data, even archives of type gzip, bz2 or deflate.
The last 5 posts were only a small summary of things that were presents at TechEd Europe. A lot of interesting news and information was shared at TechEd. All the sessions can be viewed on Channel 9.
