Big data reached a value of approximately $27 billion in 2015 and is expected to be a $100 billion market by 2020. (Survey by Snowflake Computing, 2015). The same survey report states that only 5% of enterprises have fully deployed big data strategies. The opportunity is immense and the nascent untapped potential of Big Data makes ‘Splunk’, an empowering tool for businesses around the world.

What is Splunk?

“Splunk is the ‘Google search engine’ for machine data.”  That’s how Erik Swan, Splunk’s CTO and co-founder of Splunk, described it in an interview.

In simple terms, Splunk can make machine data work better, smoother, faster and cheaper, whether it’s the company’s own IT infrastructure or a Cloud service. Behind the structure of what you see on Facebook, Twitter, YouTube, Amazon, LinkedIn, or any other web site for that matter, the crux of information resides in a hidden universe of unstructured data. Splunk enables businesses to collect, organizes and analyze this very unstructured machine data and represents a clean business-to-business play on the emerging Internet-of-Things space.

Splunk offers logical, intuitive and human-centric analytics for operational intelligence. Most importantly, it is a seamless analytics, monitoring and data visualization tool that helps you improve business capabilities by making intuitive sense out of vast quantities of unstructured data. While doing this, Splunk permits simple Google-like queries and answers about how any IT system is operating. The field of unstructured and meta-data analytics is the next phenomenon in what computing enables and Splunk is a promising leader in this burgeoning domain.
