Effective Spark with Alluxio

Alluxio, formerly Tachyon, is a memory speed virtual distributed storage system and leverages memory for storing data and accelerating access to data in different storage systems.. Alluxio has a quickly growing open source community of developers and users and is deployed at such organizations as Alibaba, Baidu, Barclays, Intel, Huawei, and Qunar. Many of these deployments use Alluxio with Spark, and some of them scale out to over PB’s of data. While Spark is already gaining great adoption, Alluxio can enable Spark to be even more effective. Alluxio bridges Spark applications with various storage systems and further accelerates data intensive applications.

In this talk, we briefly introduce Alluxio, present several ways how Alluxio can help Spark be more effective, show benchmark results with Spark RDDs and DataFrames, and describe production deployments with both Alluxio and Spark working together. In the meantime, we will provide live demos for some of the use cases.

Fighting Cybercrime: A Joint Task Force of Real Time Data and Human Analytics

Cybercrime is big business. Gartner reports worldwide security spending at $80B, with annual losses totalling more than $1.2T (in 2015). Small to medium sized businesses now account for more than half of the attacks targeting enterprises today. The threat actors behind these attacks are continually shifting their techniques and toolkits to evade the security defenses that businesses commonly use. Thanks to the growing frequency and complexity of attacks, the task of identifying and mitigating security-related events has become increasingly difficult. At eSentire, we use a combination of data and human analytics to identify, respond to and mitigate cyber threats in real-time. We capture all network traffic on our customers’ networks, hence ingesting a large amount of time-series data. We process the data as it is being streamed into our system to extract relevant threat insights and block attacks in real-time. Furthermore, we enable our cybersecurity analysts to perform in-depth investigations to: i) confirm attacks and ii) identify threats that analytical models miss. Having security experts in the loop provides feedback to our analytics engine, thereby improving the overall threat detection effectiveness. So how exactly can you build an analytics pipeline to handle a large amount of time-series/event-driven data? How do you build the tools that allow people to query this data with the expectation of mission-critical response times? In this presentation, William Callaghan will focus on the challenges faced and lessons learned in building a human-in-the loop cyber threat analytics pipeline. They will discuss the topic of analytics in cybersecurity and highlight the use of technologies such as Spark Streaming/SQL, Cassandra, Kafka and Alluxio in creating an analytics architecture with missions-critical response times.
