What is ElasticSearch? It is kind of like a database and search engine on steroids. What? That didn't make any sense. Well, it's a technology that allows you to implement a solution when you've got more data than you know what to do with. A basic example would be, searching for big data fast. It is like your own in-house mini Google.

Also, it's more like a decision-making tool. Let's imagine a scenario, remember how it was 5-10 years ago when the best you had was a relational database and you had to craft some pretty rigid statements to find what you're looking for and you could only find what you're looking for (because come on, something extra never disappoints). But with ElasticSearch, you can say 'what if?'. Whatever is needed at the right time, at the right place and the right data in the right context, it provides you. ElasticSearch cares about the numbers as well, unlike your day-to-day search engines, which only cares about the text.

Whether you're a multi-national company operating in multiple languages across different geographies, different domains, ElasticSearch has a way to pull the required information to one place.
