Johnny Suleiman - PeerSpot reviewer
Scalability is a key feature as it allows easy scaling of the platform without downtime
OpenSearch is used as a search engine for specific logs, mainly in e-commerce and monitoring the logs themselves. It is very valuable for e-commerce, enabling data analysis on application logs and customer behavior, and can be integrated with other services, including AI and machine learning…
MuhammadAzhar Khan - PeerSpot reviewer
Free to use and provides valuable monitoring capabilities
Prometheus is a scalable and flexible tool that I can deploy on any cloud platform. It is free to use and provides valuable monitoring capabilities. It allows me to save money by avoiding costs associated with AWS native services like CloudWatch or Amazon Prometheus. The ability to deploy on any cloud platform or environment, including Kubernetes, is a major advantage.

"The stability of the product is good."
"They have the good documentation in the help text and that is the reason the Amazon is the perfect solution in the current market."
"The customer service is excellent, rated nine out of ten."
"Amazon OpenSearch Service has enhanced our organization's ability to store and search large amounts of data efficiently."
"The initial set up is very easy...We really appreciate Amazon!"
"In case there is a failure, Elastic manages everything well, and there no major downtime."

Cons

"In terms of data handling capabilities with Amazon OpenSearch Service, they can be complex and managing data in comparison to other SIM solutions is a major drawback, as it is very hard to handle the data."
"One improvement I would like to see is support for auto-scaling."
"We faced documentation challenges during integration after migrating from Elasticsearch to Amazon OpenSearch Service. Better documentation on integration, query handling, and a more user-friendly UI could enhance the product."
"The configuration should be more straightforward because we had to select a lot of things."
"I would say that, basically, the configuration part is an area with a shortcoming...Some upgradation is required on the configuration side so that we can get to use it."
"One improvement I would like to see is support for auto-scaling."
"I want to see a new feature in Amazon Elasticsearch Service that allows users to create default filters for filtered levels."
"The pricing aspect is a concern. The service is way too costly. For the past month, I used only 30 to 40 MB of data, and the cost was $500. AWS could improve pricing."
"There is a need for a more comprehensive overview of exporters, especially when dealing with many of them."
"They could provide efficient logs in terms of clarity and ease of access similar to Datadog’s paid version."
"The primary area where Prometheus could be improved is in terms of pricing, particularly when used with managed services."
"If you are not quite technical, it can be pretty hard to understand the way it works and how to query data in Prometheus."
"Prometheus requires improvement on the query side."
"The setup could be made easier for new users because it requires a bit of advance knowledge or experience."
"When it comes to deployment, if you have no experience with something like a CI/CD pipeline, it might be a challenge."
"Setting up the rules in Prometheus can be confusing, making it an area where improvements are required."
 

Pricing and Cost Advice

"The solution is not expensive, but priced averagely, I will say."
"There is a community edition available and the price of the commercial offering is reasonable."
"You only pay for what you use."
"Compared to other cloud platforms, it is manageable and not very expensive."
"The product is free."
"This is an open-source solution."
"We use the solution's open-source version."
"The solution is free of cost."
"The solution is not expensive."
"Prometheus is an open-source tool."
"Prometheus is an open-source solution."
