Elastic Search

           Many times we have seen clips of a kid / adult standing in a room and all sort of numbers , characters, equations revolving around him!!!! 

          Some may see it as a millions of thoughts and numbers going through the mind of the person and being able to understand all that or something “out of world” is going to happen..

  

For me .. being into the technology is just data  

Have we ever wonder with the advent of this inventions in technology world there is so much of data that is floating around that is being used for a variety of purposes?  Every time you tap your finger on a keyboard of any size/shape/material you are unleashing data.  

From out of this world say Mars to a trivial thing like booking an Uber to work. 

So, how do I search this data, so that I be optimally used for the benefit of every one.  That’s where elastic search comes into play.   ElasticSearch is spreading it’s wings very very fast .. and I am amazed with the ease with which it functions. 

So, what is Elastic Search 

It’s a opensource software that makes massive amounts of structured and unstructured data available for search, logging, analytics and more in mission critical systems and applications. 

ElasticSearch is based on LUCENE. LUCENE is an information retrieval software library. 

Before I dive into Elastic search , let me give you a few use case of how different corporates from different businesses use Elastic Search.  

So, let me start from the Mars 

NASA : uses the ELK stack (ElasticSearch, LogStash , Kibana)  

Nasa says the uses the ELK stack to log more than 30K messages and 100k 4 times everyday from Mars ROVER to optimize our space missions 

The Guardian uses it for marketing Insights , Business Development and to capture customer sentiments. 

Goldman Sachs/ Verizon use it for IT Operations, Application Management. Verizon’s Elastic Search works for over 500 million documents.

Facebook uses it for variety of things along with ElasticSearch’s Security Plugin. 

Ebay/ Github uses it for Website Search / Internal and Intranet Search and url searchs. Github everyone know .. every line of code that your search uses Elastic Search.  

Wikimedia – Full text searches are powered by Elastic Search

UBER – Information about your ride every 4 seconds is sent to Elastic search. This is used for get your details, drivers detail and used so that they can serve you better. 

 

 

 

I was exposed to Elastic Search when Oracle PeopleSoft started using it for searches with PeopleSoft Applications. As a PeopleSoft Administrator, Elastic Search lifted off from the me the burden of maintaining SES search.  Elastic Search is fast to install and so easy to implement and almost zero maintenance. 

 

PeopleSoft Search Framework integrates with Elasticsearch to allow for high availability, failover, and scalable search deployments for PeopleSoft users 

 

The searches implemented in SES can be easily built in ElasticSearch, just Undeploy  - Re-Deploy and Rebuilt. 

 

Taking control fo the logs can also be done with ElasticSearch 

 

 

Advantage of moving to Elastic Search 

• Better crawl and search capabilities and performance 
• Better resource utilization 
• Easy to install and maintain
