Cloudera software, specifically in its distribution of Hadoop*, Navigator Encrypt*, provides transparent data encryption and key management to secure sensitive data at rest.
Intel® QuickAssist Technology Introduction
Intel® QuickAssist Technology accelerates and compresses cryptographic workloads by offloading the data to hardware capable of optimizing those functions. This makes it easier for developers to integrate built-in cryptographic accelerators into network and security applications.
The adoption of cloud computing creates many challenges and opportunities in big data management and storage. To resolve this, many independent software vendors and system integrators are working closely with worldwide IT solution vendors to use the latest technology and make improvements in big data storage. This paper discusses one such collaboration between Qihoo 360 Technology Co. Ltd.* and Intel to optimize the storage infrastructure in their Internet Portal Datacenter (IPDC).
