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

"It helps us to analyse the logs based on the location, user, and other log parameters."
"Elastic Search, being a vector database, quickly indexes data, allowing for searches based on text and data directly, which I found fascinating."
"Elastic Search is very user-friendly, and we can easily integrate it with third-party models and other AWS S3 buckets."
"The most valuable feature is the out of the box Kibana."
"A positive feature of ELK is that it directly interacts with Elasticsearch, the UI is very nice, and performance wise it's quite good too."
"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 solution is stable and reliable."
"Elastic Search makes handling large data volumes efficient and supports complex search operations."
"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

"It would be useful to include an assistant into Kibana for recommendations, advice, tutorials, or things that can help improve my daily work with Elastic Search."
"Something that could be improved is better integrations with Cortex and QRadar, for example."
"We have an issue with the volume of data that we can handle."
"They could simplify the Filebeat and Logstash configuration piece. There are a lot of manual steps on the operating system."
"Better dashboards or a better configuration system would be very good."
"Technical support should be faster."
"The most significant issue I find with Elastic Search is that it gets out of sync, and this has happened in both cases where I have implemented it."
"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)."
"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."
"The tool is not expensive. Its licensing costs are yearly."
"The solution is not expensive because users have the option of choosing the managed or the subscription model."
"We use the free version for some logs, but not extensive use."
"We are using the free open-sourced version of this solution."
"An X-Pack license is more affordable than Splunk."
"The version of Elastic Enterprise Search I am using is open source which is free. The pricing model should improve for the enterprise version because it is very expensive."
"Although the ELK Elasticsearch software is open-source, we buy the hardware."

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.
