In the recent years – the term BigData has been gaining popularity as well and there has been a paradigm shift is the volume of information and the ways in which it can be extracted from this data.
ELK is one of the few new-age frameworks which is capable of handling Big Data demands and scale.
Over the years the ELK stack has become quite popular. And for a good reason. It is a very robust, mature and feature rich framework. ELK is used by large enterprises, government organizations and startups alike. The ELK stack has a very rich and active community behind it. They develop, share and support tons of source code, components, plugins and knowledge about these tools freely and openly.
If you ever had to search a database of retail products by description, find similar text in a body of crawled web pages, or search through posts on a blog. You wonder if there was a search tool, which could make such jobs easy.
In this course, we will focus on one such enterprise search engine- The ElasticSearch which is one of the core components of the ELK stack. We will look at the overview and explore the technology that goes into this tool.
Knowledge and experience about ELK and ElasticSearch could be very valuable for your career. The latest stats and figures show some amazing numbers like jobs requiring these skill sets pay higher than most of the jobs posted on public job boards within the US and annual salaries for professionals could be as high as $100,000. That is the exact reason why you must enroll in this course and take your career to the next level.
As the title suggests – this course aims to provide you enough knowledge about ELK and ElasticSearch so that you can run and operate your own search cluster using these components together.
