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.

Quotes from Members

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

Pros

"The initial set up is very easy...We really appreciate Amazon!"
"Regarding valuable features of the solution, we found with the process, which we have used in both cases where we used the solution that while you're seeing the streaming of data, you can analyze in the initial phase what sort of data you are streaming and whether it is valuable."
"It enables us to efficiently search and retrieve our event data, offering us a versatile approach to locate specific information within these logs."
"The most valuable features of Amazon Elasticsearch are ease of use, native JSON, and efficiency. Additionally, handles many use cases and search grammar was useful."
"This service already sorts data like vectors. They have classified the storage pre-defined."
"It's a good log management platform. In terms of infrastructure management, it's good."
"I would definitely recommend Amazon OpenSearch Service to other professionals due to its fast and reliable search capabilities."
"Our customers have seen tangible benefits from Amazon OpenSearch Service, especially in terms of their applications running smoothly, so they do get a return on investment."
"The best thing about Prometheus is its integration."
"It has lots of APIs and libraries to integrate with any kind of language."
"The product is easy to maintain."
"It is an efficient solution."
"The sky is the limit because the solution is a flexible open box that can be used vastly to do anything you need to monitor applications."
"The most valuable feature of Prometheus is the ease of pulling the metrics."
"The feature I found most valuable is the number of integrations. It is the industry standard for metrics."
"The solution offers an easy way to install and scratch values."
 

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."
"It would be beneficial to have some level of customization available in the managed service, tailored to the specific use cases of the end users."
"One improvement I would like to see is support for auto-scaling."
"One glaring issue was with our mapping configuration as the system accepted the data we posted, but after a few months, when we attempted complex queries, we realized the date formatting had become problematic."
"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 problem with the database. Amazon only provides the hosting to run our applications bias, but there is no option to manage the database within the Elasticsearch product."
"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."
"I want to see a new feature in Amazon Elasticsearch Service that allows users to create default filters for filtered levels."
"The solution's error handling part could be improved."
"The scalability must be improved."
"Prometheus can be initially difficult for users since it has its query language, PromQL. The minimalistic interface is complicated to understand. They need to improve their interface so that users who don't know PromQL can also use it. You can only leverage the tool when you know PromQL."
"If you want to collect details of metrics, you should be able to write a query for it directly. I want the product to offer better queries for the metrics."
"Prometheus can definitely improve its visualization. For example, the matrices represented in Prometheus do not have a very good visualization on their dashboard."
"There is a need for a more comprehensive overview of exporters, especially when dealing with many of them."
"The setup could be made easier for new users because it requires a bit of advance knowledge or experience."
"The solution has shortcomings regarding security monitoring-oriented features to support custom use cases, like out-of-the-box test scenarios and threat-related use cases of its users."

"Compared to other cloud platforms, it is manageable and not very expensive."

"The solution is not expensive, but priced averagely, I will say."
"This is an open-source solution."
"Prometheus is available as an open-source product."
"My company uses the open-source version of the product."
