IAI has built and constantly been improving an OpenStack-based private cloud, named DRACO (Distributed Robust Agile Cloud Operandi). Current hardware specifications include (i) 16 nodes server cluster with Intel XEON Chips, with a total of 192 cores, (ii) aggregate 512 GB DRAM, (iii) 16 x 64 GB for data storage, (iv) 500G for Virtual Machine image storage, (v) 1 Gbps Ethernet. As Infrastructure-as-a-Service (IaaS), DRACO provides scalable compute and store services via Nova, Swift and Glance with a multi-user resource sharing framework. As Software-as-a-Service (SaaS), DRACO deploys configurable Hadoop ecosystem as a stand-alone virtual machine, namely Elastic LOCOMOTIVE, and provides capabilities to ingest heterogeneous data (including, but not limited to social media, ISR, communication network) with an easy-to-use Hadoop Management framework. Currently, Elastic LOCOMOTIVE provides services including HDFS (a distributed file system), MapReduce framework (to support data intensive parallel processing), Zookeeper (to provide centralized coordination services such as distributed synchronization, group management, and configuration maintainance), HBase (a NoSQL database), Hive (a data warehouse system), and Oozie (a workflow system to manage Hadoop jobs). DRACO is a flexible system with a unified user interface. It can easily admit new service deployment, and allow users to easily configure/re-configure the services. DRACO is also supported by 6 HP OpenFlow switches to enable Software Defined Networking.
