Customer engagement & documentation about APIs are great, but it would be good if the UI is a bit more intuitive for search experience
I use the solution mainly to search the logs and to search for VMs by their names or subscription names. I wouldn't rate it great since the logs are a bit complicated The solution was really pretty good. The customer engagement was good. The presented documentation or exposure to the APIs to get…

Captures data from all other sources and becomes a MOM aka monitoring of monitors
Scalability and ROI are the areas they have to improve. Their license terms are based on the number of cores. If you increase the number of cores, it becomes very difficult to manage at a large scale. For example, if I have a $3 million project, I won't sell it because if we're dealing with a 10 TB or 50 TB system, there are a lot of systems and applications to monitor, and I have to make an MOM (Mean of Max) for everything. This is because of the cost impact. Also, when you have horizontal scaling, it's like a multi-story building with only one elevator. You have to run around, and it's not efficient. Even the smallest task becomes difficult. That's the problem with horizontal scaling. They need to improve this because if they increase the cores and adjust the licensing accordingly, it would make more sense.

Quotes from Members

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

Pros

"The customer engagement was good."
"The search functionality time has been reduced to a few milliseconds."
"It provides good access capabilities to various platforms."
"The amount of flexibility and agility is really assuring."
"Azure Search is well-documented, making it easy to understand and implement."
"Because all communication is done via the REST API, data is retrieved quickly in JSON format to reduce overhead and latency.​"
"The product is extremely configurable, allowing you to customize the search experience to suit your needs."
"Creates indexers to get data from different data sources."
"Search is really powerful."
"The search speed is most valuable and important."
"The ability to aggregate log and machine data into a searchable index reduces time to identify and isolate issues for an application. Saves time in triage and incident response by eliminating manual steps to access and parse logs on separate systems, within large infrastructure footprints."
"Elastic Search makes handling large data volumes efficient and supports complex search operations."
"Logsign provides us with the capability to execute multiple queries according to our requirements. The indexing is very high, making it effective for storing and retrieving logs. The real-time analytics with Elastic benefits us due to the huge traffic volume in our organization, which reaches up to 60,000 requests per second. With logs of approximately 25 GB per day, manually analyzing traffic behavior, payloads, headers, user agents, and other details is impractical."
"The AI-based attribute tagging is a valuable feature."
"It is stable."
"It is highly valuable because of its simplicity in maintenance, where most tasks are handled for you, and it offers a plethora of built-in features."
 

Cons

"The after-hour services are slow."
"Adding items to Azure Search using its .NET APIs sometimes throws exceptions."
"For SDKs, Azure Search currently offers solutions for .NET and Python. Additional platforms would be welcomed, especially native iOS and Android solutions for mobile development."
"The solution's stability could be better."
"The initial setup is not as easy as it should be."
"They should add an API for third-party vendors, like a security operating center or reporting system, that would be a big improvement."
"The pricing is room for improvement."
"For availability, expanding its use to all Azure datacenters would be helpful in increasing awareness and usage of the product.​"
"I would like to be able to do correlations between multiple indexes."
"The one area that can use improvement is the automapping of fields."
"Dashboards could be more flexible, and it would be nice to provide more drill-down capabilities."
"Elastic Search needs to improve its technical support. It should be customer-friendly and have good support."
"Kibana should be more friendly, especially when building dashboards."
"It was not possible to use authentication three years back. You needed to buy the product's services for authentication."
"The GUI is the part of the program which has the most room for improvement."
"There are some features lacking in ELK Elasticsearch."
 

Pricing and Cost Advice

"The cost is comparable."
"​When telling people about the product, I always encourage them to set up a new service using the free pricing tier. This allows them to learn about the product and its capabilities in a risk-free environment. Depending on their needs, the free tier may be suitable for their projects, however enterprise applications will most likely required a higher, paid tier."
"For the actual costs, I encourage users to view the pricing page on the Azure site for details.​"
"I think the solution's pricing is ok compared to other cloud devices."
"I would rate the pricing an eight out of ten, where one is the low price, and ten is the high price."
"The solution is affordable."
"ELK has been considered as an alternative to Splunk to reduce licensing costs."
"The price of Elastic Enterprise is very, very competitive."
"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."
"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 paying $1,500 a month to use the solution. If you want to have endpoint protection you need to pay more."
"This product is open-source and can be used free of charge."
"The pricing structure depends on the scalability steps."
"An X-Pack license is more affordable than Splunk."
