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.

Scales linearly and vertically; primarily used in AI
If I am not wrong, IDOL is working to release improvements in new capabilities in the next six months. There is room for improvement in some very important capabilities in visual analytics. They have been focusing on improving the face recognition algorithm. The accuracy of object detection could be improved as well and I know they are working on that at the moment. I would like to see some machine learning capabilities added to the next release.

Quotes from Members

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

Pros

"The products comes with REST APIs."
"The solution offers good stability."
"From the customer side, Elastic Search is super fast and very efficient, delivering results quickly."
"This product has notably improved the way we store and use logs, from having a more user-friendly, centralized solution (for those who just needed a quick glance, without being masters of sed and awk) to implementing various mechanisms for machine-learning from our logs, and sending alerts for anomalies."
"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 observability is the best available because it provides granular insights that identify reasons for defects."
"This is a very rich product, and it's got a very wide functionality, and a wide range of functionalities which I don't see in the other products, especially not in the cheaper ones."
"Elastic is doing a fantastic job by doing the indexing, and with a couple of indexing configurations, we are able to achieve our goal even though we are maintaining a huge amount of data per day, around millions of transactions for each record."
"IDOL is a scalable solution: If a client needs to process more unstructured media content, they can scale IDOL both linearly and vertically, and you can scale this solution very easily."
"Satisfaction and ability to find relevant content has increased over 50% based on our before and after survey results."
"Enterprise search success (finding what documents you're looking for) has gone up over 30% with users finding their hit on the first page of results as opposed to the 2,3,4th or giving up entirely."
"Speed improvements over older Fetch architecture."
"Capability of processing and analysing unstructured data, like audio and video analysis."
"IDOL has several important visual analytics, like face recognition and object detection and recognition."
 

Cons

"I would rate the stability a seven out of ten. We faced a few issues."
"Elasticsearch could be improved in terms of scalability."
"I would rate technical support from Elastic Search as three out of ten. The main issue is a general sum of all factors."
"This product could be improved with additional security, and the addition of support for machine learning devices."
"I would like to see more open source tools and testing as well as a signature analysis in the solution."
"The upgrade experience and inflexibility with fields keeps Elastic Search from being a perfect 10."
"New Relic could be more flexible, similar to Elasticsearch."
"According to me, as far as I have seen, people will start moving from Elastic Search sooner or later. Why? Because it is expensive."
"Technical support could improve a lot."
"There is room for improvement in some very important capabilities in visual analytics. They have been focusing on improving the face recognition algorithm. The accuracy of object detection could be improved as well and I know they are working on that at the moment."
"On-premise implementation and installation is very complicated."
"IDOL's tech support needs improvement."
"The interface needs to be mobile friendly, which I understand is in the backlog of future improvements."
"Understanding how to optimize Lua Scripting configuration to improve performance. Lua Scripts added to a CFS configuration can cause the CFS processing to slow down, if the scripts are not scoped to only run against specific indexing jobs or database content."
 

Pricing and Cost Advice

"The premium license is expensive."
"To access all the features available you require both the open source license and the production license."
"We are paying $1,500 a month to use the solution. If you want to have endpoint protection you need to pay more."
"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."
"The solution is less expensive than Stackdriver and Grafana."
"I rate Elastic Search's pricing an eight out of ten."
"The price of Elastic Enterprise is very, very competitive."
"The price could be better."
