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.

MapR: One Of These Things Is Not Like The Others MapR's guiding principles are practicality and performance, so it didn't think twice about chucking the Hadoop Distributed File System out of its Hadoop software distribution. HDFS had (and still has, MapR argues) reliability and availability flaws, so MapR uses the proven Network File System (NFS) instead. In the bargain, MapR claims to get "twice the speed with half the required hardware." The NFS choice also enabled MapR to support near-real-time data streaming using messaging software from Informatica. MapR competitors Cloudera and Hortonworks can't stream data because HDFS is an append-only system.
MapR's latest quest for better performance (regardless of open source consequences) is the M7 software distribution, which the vendor says delivers high-performance Hadoop and HBase in one deployment. Many users have high hopes for HBase because it's the NoSQL database native to the Apache Hadoop platform (promising database access to all the data on Hadoop). But HBase is immature and still suffers from flaws, including instability and cumbersome administration.
M7 delivers two times faster performance than HBase running on standard Hadoop architectures, says MapR, because the distribution does away with region servers, table splits and merges and data compaction steps. MapR also uses its proprietary infrastructure to support snapshotting, high availability and system recovery for HBase.
If you're an open source purist swayed by arguments about system portability, MapR may not be the vendor for you. But we've talked to high-scale customers who have chosen MapR for better performance. Want to give it a try? MapR is available both on Amazon Web Services and the Google Compute Engine.
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?
