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

"I would definitely recommend Amazon OpenSearch Service to other professionals due to its fast and reliable search capabilities."
"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."
"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 business analytics capabilities are the most important feature it provides."
"Amazon OpenSearch Service provides a managed database solution, so we don't need to manage everything ourselves."
"The stability of the product is good."
"It's a good log management platform. In terms of infrastructure management, it's good."
"In case there is a failure, Elastic manages everything well, and there no major downtime."
"The most valuable feature is that we can receive information in different formats."
"The product’s scalability is valuable."
"Stability-wise, I rate the solution a ten out of ten."
"Prometheus is a great solution for monitoring."
"The most valuable features of Prometheus for metrics collection and monitoring are its stability, robustness, and rich set of features."
"Prometheus is a scalable and flexible tool that I can deploy on any cloud platform."
"I like its lightweight configuration functions."
"The best thing about Prometheus is its integration."
 

Cons

"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."
"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."
"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."
"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 price is fair yet leans towards the expensive side. I'd rate it five out of ten with respect to capabilities vs. cost."
"There is a tool called Prometheus Exporter that doesn't work well."
"When it comes to deployment, if you have no experience with something like a CI/CD pipeline, it might be a challenge."
"Lacks the ability to clusterize."
"The simplicity of the query language could be improved. The current query language is not easy to work with."
"The DSL could be improved."
"The UI and GUI are areas of concern in the product."
"Improvements could be made to the user interface."
"Prometheus has a learning curve when setting it up. It definitely requires a little bit more hands-on than other solutions. It is an open source solution which means you do need to go through and read the literature that they have online for setting it up. The setup could be made easier."
 

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."
"Compared to other cloud platforms, it is manageable and not very expensive."
"You only pay for what you use."
"The price of Prometheus is good, it is affordable because it is open source and there is no cost to it. You put it on your own server and the costs incurred completely depend on how you set it up."
"Prometheus is an open-source solution."
"Prometheus is available as an open-source product."
"Prometheus is an open-source tool."
"The solution is open source."
"The product is free."
"The tool is open-sourced."
"Prometheus is an open-source solution."
