Logging and vector search have transformed observability and empowered reliable ai agents
Elastic Search is not specifically being used for certain purposes. I deploy Elastic Search database on the cloud and use cloud services so that nobody can attack. However, I do not use Elastic Search to resolve attack issues. The basic main purpose of Elastic Search, as of now, I feel it can do more in the AI area. Sometime I saw that when I am developing RAG and have to generate the embeddings, which I call metadata, sometimes it tries to fail. That durability or issue handling should be improved, but apart from that, I did not find anything as of now. As per my use case, whatever I am using seems pretty good. Apart from that, some definitely improvement will be there. One improvement is that it should be faster. Whenever I am searching any logs, it takes much time. For example, if I open my log in Notepad or a similar tool, I can search the text within a second. With Elastic Search, it takes a little bit of time, ten to fifteen seconds. That can be improved. Sometimes, engineers take time to assign when I create a ticket.

Robust solution with good value
Microsoft FAST is quite robust. Our clients are quite happy with it. For other users who already have a solution in place, we recommend Microsoft FAST because it is more compatible and you can organize the solution with Microsoft components. If you are with any other third party, there could be a chance that the required output is not what you would expect. But with Microsoft, it will work better. It is compatible with the older generation systems, so you can offer it. On a scale of one to ten, I would give Microsoft FAST an eight because I'm quite comfortable with it.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I would say that Elasticsearch is better than all the other solutions."
"The initial setup is very easy for small environments."
"Data indexing of historical data is the most beneficial feature of the product."
"The stability of Elasticsearch was very high, and I would rate it a ten."
"Elastic Search, being a vector database, quickly indexes data, allowing for searches based on text and data directly, which I found fascinating."
"The pricing and license model are clear: node-based model."
"Elastic Enterprise Search is a nonstructured database that can manage large amounts of nonstructured data."
"The forced merge and forced resonate features reduce the data size increasing reliability."
"Microsoft FAST is quite robust. Our clients are quite happy with it."
"Microsoft FAST is quite robust, our clients are quite happy with it, and for other users who already have a solution in place, we recommend Microsoft FAST because it is more compatible and you can organize the solution with Microsoft components."
"Microsoft FAST is a really amazing search application."
 

Cons

"The metadata gets stored along with indexes and isn't queryable."
"Elastic Enterprise Search could improve the report templates."
"We see the need for some improvements with Elasticsearch. We would like the Elasticsearch package to include training lessons for our staff."
"Maybe Elastic Search could improve the analytics part of the search so it can be more powerful to the user."
"The GUI is the part of the program which has the most room for improvement."
"There are some features lacking in ELK Elasticsearch."
"Elastic Enterprise Search could improve its SSL integration easier. We should not need to go to the back-end servers to do configuration, we should be able to do it on the GUI."
"Both the graph feature and the reporting feature are a little bit lacking. The alerting also needs to be improved."
"If there is any change in a system or a configuration or an update, we might face some issues."
"We do get support from Microsoft, but the response is quite slow."
 

Pricing and Cost Advice

"This product is open-source and can be used free of charge."
"The basic license is free, but it comes with a lot of features that aren't free. With a gold license, we get active directory integration. With a platinum license, we get alerting."
"The tool is not expensive. Its licensing costs are yearly."
"The price of Elasticsearch is fair. It is a more expensive solution, like QRadar. The price for Elasticsearch is not much more than other solutions we have."
"There is a free version, and there is also a hosted version for which you have to pay. We're currently using the free version. If things go well, we might go for the paid version."
"Elastic Search is open-source, but you need to pay for support, which is expensive."
"ELK has been considered as an alternative to Splunk to reduce licensing costs."
"The solution is not expensive because users have the option of choosing the managed or the subscription model."

Questions from the Community

What is your experience regarding pricing and costs for ELK Elasticsearch?
Elastic Search is easy to use in Azure cloud. Mostly, my full company uses Azure cloud, so it is easy to use. Cost-wise, my company found Elastic Search is good. Cost matters. Based on cost and use...
What needs improvement with ELK Elasticsearch?
The initial configuration could be easier; at first, the learning curve is a little high, and over time, it becomes easier. For me, the initial configuration might be improved.
What is your primary use case for ELK Elasticsearch?
We use Elastic Search for a research application based on paper study, and the primary usage is for indexing the data and then functioning in a similar way to an e-commerce search bar.
