Big Data - Many Talk About It, We Do It!

Analytics 750x410

We’ve been working on big data topics in our labs and with our clients for quite a while now. Over time, we built a framework of technologies and utilities we can build data driven projects on. We call it ti&m analytics.

The Architecture

ti&m analytics is based on the Lambda Architecture, an industry best practice using only open source technologies. Data driven or big data ventures have requirements in two categories:

  • Real-time: monitoring, recommendations, fraud detection
  • Historic: analysis of classifications, statistics, exit points and so on

In order to fulfill those requirements, Lambda uses the following four main building blocks:

  • Data integration integrates data from all sources. These can be REST services or sensors (push services) as well as file loads and other periodic loads (pull loads).
    Technologies: kafka, Storm
  • Real time / speedlayer is mainly used for monitoring and alerting use cases and is not able to calculate anything backwards in time.
    Technologies: spark streaming, atmosphere.io
  • Batch / serving layer is used for calculations on historic data and the storing of such. Technologies: HDFS, Spark, HBase
  • Visualization / data access results are displayed either in dashboards or interactive tools as Tableau or using Hive.
    Technologies: ti&m dashboard, Tableau, Hive

Our approach

Using the Lambda Architecture, we built numerous solutions ranging from web analytics to social media monitors and banking appliances. This allowed us to extract a reusable framework including integration for social media (Twitter/Facebook), social collaboration (jive), user tracking across multiple channels, core banking solutions and many more to come.

We worked with a solid library of already implemented analyses, for example process analysis to visualize where clients/users get stuck during processes or where they exit. Other examples would be sentiment analysis, usage statistics by geo location as well as identification of top users and what they are focused on.

Visualization is the key to any data driven initiative! We built a customizable dashboard to visualize real time and historical data. As we don’t believe in anything proprietary, the collected data can also be used with visualization tools like Tableau or interactive querying using Hive, Pig or Drill. For recommender systems or personalized content, data can also be fed into business applications.

Regulation or data governance might require to have all data on premise. Our solution ships using virtual machines and can be installed on the existing infrastructure. We also offer to have shared and privately hosted infrastructure in our datacenters. Consequently, the solution is perfectly suitable to build MVPs, but also for long term production usage.

Implementation

Digital analytics as a whole (organisational and technical) is very complex, therefore implementation has to be done step by step. Primary data sources and how they yield business values have to be identified. Imminent business value can’t always be guaranteed as value in data grows over time. A good example would be collecting usage data, which over time allows deeper insights into how users behave and how they react to changes.

Once the primary goal and the long-term vison are agreed upon, implementation starts. We set up the needed infrastructure either on or off the premise, with the main goal being the full integration within the first iteration. Additionally, the data architecture is defined, including how and where data is stored and in what access patterns it is used. Last but not least, we set up the visualisation using our ti&m dashboard or Tableau/Hive etc.

While in the security field the terms authentication and authorization have a clearly defined definition, with the introduction of concepts such as “delegated authorization” ambiguity might arise. However, it seems that we know what we intend and therefore should we even bother with such discussions?
