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

"A nonstructured database that can manage large amounts of nonstructured data."
"On the subject of pricing, Elastic Search is very cost-efficient, as you can host it on-premises, which would incur zero cost, or take it as a SaaS-based service, where the expenses remain minimal."
"The observability is the best available because it provides granular insights that identify reasons for defects."
"The fact that you can dump any type of format in the database without any specific reformatting is fantastic."
"Search is really powerful."
"The best feature of Elastic Search is it does exactly what it says."
"Elasticsearch includes a graphical user interface (GUI) called Kibana. The GUI features are extremely beneficial to us."
"The flexibility and the support for diverse languages that it provides for searching the database are most valuable. We can use different languages to query the database."
"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 quite robust. Our clients are quite happy with it."
"Microsoft FAST is a really amazing search application."
 

Cons

"Elasticsearch could improve by honoring Unix environmental variables and not relying only on those provided by Java (e.g. installing plugins over the Unix http proxy)."
"I found an issue with Elasticsearch in terms of aggregation. There is a maximum of 10,000 entries, so the limitation means that if I wanted to analyze certain IP addresses more than 10,000 times, I wouldn't be able to dump or print that information."
"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."
"I know many customers who lost their data and could not recover it."
"Something that could be improved is better integrations with Cortex and QRadar, for example."
"I think the GUI part of the solution has the most room for improvement."
"Maybe Elastic Search could improve the analytics part of the search so it can be more powerful to the user."
"Scalability and ROI are the areas they have to improve."
"We do get support from Microsoft, but the response is quite slow."
"If there is any change in a system or a configuration or an update, we might face some issues."
 

Pricing and Cost Advice

"The premium license is expensive."
"We are using the open-sourced version."
"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."
"ELK has been considered as an alternative to Splunk to reduce licensing costs."
"​The pricing and license model are clear: node-based model."
"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."
"Although the ELK Elasticsearch software is open-source, we buy the hardware."
"To access all the features available you require both the open source license and the production license."
