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

"The most valuable feature for us is the analytics that we can configure and view using Kibana."
"Even compared to Splunk, Elastic Search has a good easy-to-use user interface, as even non-technical people can easily search and easily observe the logs and easily track the applications."
"Dashboard is very customizable."
"The search speed is most valuable and important."
"It is a stable and good platform."
"Elastic Search, being a vector database, quickly indexes data, allowing for searches based on text and data directly, which I found fascinating."
"The most valuable features of Elastic Enterprise Search are it's cloud-ready and we do a lot of infrastructure as code. By using ELK, we're able to deploy the solution as part of our ISC deployment."
"The most valuable features are the ease and speed of the setup."
"Microsoft FAST is quite robust. Our clients are quite happy with it."
"Microsoft FAST is a really amazing search application."
"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."
 

Cons

"The one area that can use improvement is the automapping of fields."
"The price could be better. Kibana has some limitations in terms of the tablet to view event logs. I also have a high volume of data. On the initialization part, if you chose Kibana, you'll have some limitations. Kibana was primarily proposed as a log data reviewer to build applications to the viewer log data using Kibana. Then it became a virtualization tool, but it still has limitations from a developer's point of view."
"Elastic Search could benefit from a more user-friendly onboarding process for beginners."
"I think Elastic Search could be improved by introducing more AI features, particularly for complex queries and aggregator functions to enhance usability and readability."
"The UI point of view is not very powerful because it is dependent on Kibana."
"I think the biggest issue we had with Elastic Search was regarding integrations with our multi-factor authentication tool."
"There are some features lacking in ELK Elasticsearch."
"It was not possible to use authentication three years back. You needed to buy the product's services for authentication."
"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 price of Elastic Enterprise is very, very competitive."
"We are using the free open-sourced version of this solution."
"It can be expensive."
"The cost varies based on factors like usage volume, network load, data storage size, and service utilization. If your usage isn't too extensive, the cost will be lower."
"We are using the open-sourced version."
"Elastic Search is open-source, but you need to pay for support, which is expensive."
"We are using the Community Edition because Elasticsearch's licensing model is not flexible or suitable for us. They ask for an annual subscription. We also got the development consultancy from Elasticsearch for 60 days or something like that, but they were just trying to do the same trick. That's why we didn't purchase it. We are just using the Community Edition."
"I rate Elastic Search's pricing an eight out of ten."
