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.

Daily orchestration of complex ai workflows has boosted my research and automation capabilities
Orchestration primarily decides which agent handles which part of a task and manages errors, retries, and complete state while maintaining the workflow effectively. On the orchestration side, branching, looping, and human approvals support non-linear workflows in production environments with real-time access. Through refined and improved prompts, this helps in closing the loop with actual users. One unique feature that stood out is that every step in the workflow can pause or recover from failures. Instead of finishing the entire agent in one go, this approach is interesting because if there is a minor change in a previously completed step regarding the state, I can re-edit and restart from the beginning. This is truly impressive.

Quotes from Members

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

Pros

"The difference in performance of Elastic Search is outstanding; if we compare a traditional database or service for search and index products or, in this case, papers, the difference is outstanding."
"Elastic Search's main advantages are the visuals that represent and visualize all entities and system components in a simplified diagram, which provides the ability to identify which component in the system has an issue."
"This has improved our organization because we articulated Kubernetes, Docker, and GitHub with amazing simplicity in the scaling up of our service."
"There are a lot of good things about this solution. First, it is an extremely fast search. We have quite an extensive number of logs, and we can search through billions of documents in just a few minutes, and get the results we're looking for."
"My favorite feature is always aggregations and aggregators; you do not have to do multiple queries and it is always optimized for me, and I always got the perfect results because I am using full text search with aliases and keyword search, everything I am performing it, and it always performs out of the box."
"I really like the visualization that you can do within it; that's really handy, and product-wise, it is a very good and stable product."
"I find the solution to be fast."
"Using real-time search functionality to support operational decisions has been helpful."
"Glean Platform has increased productivity by at least one hundred hours per week for my organization."
"The best features Glean Platform offers include the ability to create my own agents, for example, I created a self-service agent for my stakeholders, so rather than email me, I sent them a link to an agent where the agent asks them questions and drills down to exactly what they need, and then I get a qualified response from them."
"The major impact that I have noticed is how business users are now being impacted and they are using the platform because they understand it easily."
"Productivity has really skyrocketed."
"Since I have joined, I have built around ninety agents with Glean Platform, and it has saved our organization around twenty-seven hours a week for each user, and it has also positively impacted our ARR."
"Life became so easy when we started using Glean Platform."
"Glean Platform has positively impacted our organization, especially in terms of productivity for both us and our customers."
"The best features Glean Platform offers are mostly the view, which I think is very good, and what I find most helpful about the view is that the user interface is very good, making it very easy to chat with the chatbot and get all the material that I want in the way that I need it."
 

Cons

"I found an issue with Elasticsearch in terms of aggregation. They are good, yet the rules written for this are not really good."
"Elasticsearch could be improved in terms of scalability."
"We had initially planned to expand use of ELK because of its cheap price and the services that are included, but given the difficulty with implementation we've decided to go with Nagios instead."
"Kibana should be more friendly, especially when building dashboards."
"The one area that can use improvement is the automapping of fields."
"An improvement would be to have an interface that allows easier navigation and tracing of logs."
"Dashboards could be more flexible, and it would be nice to provide more drill-down capabilities."
"It is hard to learn and understand because it is a very big platform. This is the main reason why we still have nothing in production. We have to learn some things before we get there."
"Sometimes Glean Platform gets slowed down."
"Currently, Glean Platform does not integrate with Teams, Microsoft-owned platforms."
"I tried pulling in an architecture diagram of a workflow, and it pulled in some other image instead."
"My experience with pricing, setup cost, and licensing is that the licenses were expensive, and it was hard to convince the company to adopt based on that."
"There are multiple ways in which Glean Platform can be improved."
"My experience with pricing, setup cost, and licensing for Glean Platform reveals limited options, and I wish there was more customization available."
"In workflow agents, I would prefer that we do not use AI in every step and instead we have a toggle button or something which can configure whether AI should be used in this specific search field or not, or in this specific node or not, because currently it's using AI in all nodes which sometimes messes up the output."
"Also, the latency that the platform offers is a little high right now; what I have noticed is that on a particular query, the user has to wait a long time in order to get responses."
 

Pricing and Cost Advice

"This is a free, open source software (FOSS) tool, which means no cost on the front-end. There are no free lunches in this world though. Technical skill to implement and support are costly on the back-end with ELK, whether you train/hire internally or go for premium services from Elastic."
"We are using the free version and intend to upgrade."
"Elastic Search is open-source, but you need to pay for support, which is expensive."
"It can move from $10,000 US Dollars per year to any price based on how powerful you need the searches to be and the capacity in terms of storage and process."
"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 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 an open-source product."
"The solution is not expensive because users have the option of choosing the managed or the subscription model."
