From Amazon to Splunk, here's a look at the big data innovators that are now pushing Hadoop, NoSQL and big data analytics to the next level.

Cloudera Addresses Hadoop Analytics Gap Cloudera is the #1 provider of Hadoop software, training and commercial support. From this position of strength, Cloudera has sought to advance the manageability, reliability and usability of the platform.
During 2012, the discussion turned from convincing the broad corporate market that Hadoop is a viable platform to convincing people that they can gain value from the masses of data on a cluster. But to do that, we'll need to get past one of Hadoop's biggest flaw: the slow, batch-oriented nature of MapReduce processing. Tackling the problem head on, Cloudera has introduced Impala, an interactive-speed SQL query engine that runs on the existing Hadoop infrastructure. Two years in development and now in beta, Impala promises to make all the data in the Hadoop Distributed File System (HDFS) and Apache HBase database tables accessible for real-time querying. Unlike Apache Hive, which offers a degree of SQL querying of Hadoop, Impala is not dependent on MapReduce processing, so it should be much faster.
There's a lot riding on Impala. What's not yet clear is whether it will mostly work with conventional relational tools or whether it will cut many of them out of the picture. Thus, all eyes will be on Cloudera in 2013.
6 Tools to Protect Big DataMost IT teams have their conventional databases covered in terms of security and business continuity. But as we enter the era of big data, Hadoop, and NoSQL, protection schemes need to evolve. In fact, big data could drive the next big security strategy shift.
Big Data Brings Big Security ProblemsWhy should big data be more difficult to secure? In a word, variety. But the business wonít wait to use it to predict customer behavior, find correlations across disparate data sources, predict fraud or financial risk, and more.
InformationWeek Tech Digest, Nov. 10, 2014Just 30% of respondents to our new survey say their companies are very or extremely effective at identifying critical data and analyzing it to make decisions, down from 42% in 2013. What gives?
