Hey, everyone.
And welcome back.
Now, in today's video, we are going to discuss about the Amazon Open search.
Now, at a high level overview, Amazon Open search allows us to ingest the data, search the data and
perform visualization on top of the data.
And this can be explained in the diagram where you have certain data sources like log files, matrix
documents, etc. You feed in all of these to the Amazon open search, and once the data is ingested,
then you can go ahead and perform searching.
You can create dashboards and other things.
Now, note that Amazon Open Search is initially based on the forked version of Elasticsearch.
So if you work with Elasticsearch, then working with open search will be much more simpler.
So let's go ahead and quickly look into it.
Now for today's video, I already have open search configured for the overall demo.
Now, if you look into this open search related configuration, a very simple cluster based on one availability
zone based on RT three dot small and it has a EBS storage of ten GB.
Now as we're discussing that it allows ingesting, searching and visualization of data.
Now if we look into the open search, there is some sample data that is imported over here.
Now if I quickly expand this, you'll see you will be able to search the data and events quite easily.
For example, all of these data is parsed.
For example, let's say you want to search on what are the operating system images that are available.
So basically these are certain set of logs.
And based on these logs you can search for, for example, as you're discussing the operating system
over here, we can easily identify that 22% is Windows seven.
You have Windows eight, you have Windows XP and so on.
And based on that, a lot of dashboards can be created easily.
For example, I also have a sample dashboard that is available as we're discussing.
We have visitors by operating system and you see you have a nice dashboard that can easily give you
information.
You have dashboard related to other information as well.
Let's go ahead and look into it.
You have a heat map, you have a source destination chart and various others.
So I hope with this at a very high level overview, you understood what open search intends to do.
Now, one thing to note is that the Amazon Open Search service used to be called as Amazon Elastic Search
Service when it was initially launched, but at a later stage there were a lot of issues between Amazon
and Elastic, which used to take care of elastic search.
For example, you have the elastic over here.
Let me quickly show you.
So Elastic is one of the organizations where you can go ahead and download the stack and various other
tools, and they also provide the official support on the elastic search.
Since there were a lot of tussles and legal issues between them, Amazon had to change the name from
elastic search to open search, and I was reading in the elastic search.
They had also specified details related to open search.
So it is not a very polite description, but let's read it.
So it states that the open search is not an elastic search and is not a partnership with elastic.
The company behind the elastic search.
Now Amazon Elastic Search is based on an older fourth version of elastic search and offers fraction
of functionality, choice and support available directly from elastic.
And this is also one of the reasons why a lot of organizations, if they are planning to work dedicatedly
based on the l stack I have seen, they do not really opt for the open search service.
They generally use the elastic search service and I have seen many of the feature differences between
open search and elastic, although the base might remain to be the same, but with elastic you get the
official support.
And also there are certain differences that you might see.
However, one of the benefits of open search is that, you know, you do not really have to opt for
the trial, do not have to go in with a partnership with elastic.
Just quickly create an open search service through Amazon and your overall cluster will be ready within
15 to 20 minutes.
So this is one of the quick ways to get things going.
And many of the organizations who wants to keep it simple do not really want to go to advance into things.
They use the open search service.
So this is a very high level overview about the Amazon open search.
And with this will conclude today's video.
