Executive SummaryUpdated on Jul 24, 2024

Prometheus and Amazon OpenSearch Service compete in monitoring and search analytics. Amazon OpenSearch Service has the upper hand due to its integrated solution and scalability.

Features: Prometheus offers reliable time-series data storage, a powerful alerting system, and simplicity. Amazon OpenSearch Service provides comprehensive search, visualization, and real-time analytics features, and integrates well with AWS services.

Room for Improvement: Prometheus needs better scalability, enhanced data visualization tools, and improved query language support. Amazon OpenSearch Service could use a more intuitive setup process, enhanced documentation, and customizable dashboards.

Ease of Deployment and Customer Service: Prometheus is easy to deploy, especially in Kubernetes, but it requires manual setup and maintenance. Community support is commendable. Amazon OpenSearch Service benefits from managed service, reducing deployment complexities and seamless integration with AWS services. Users report satisfaction with AWS customer support.

Pricing and ROI: Prometheus is cost-effective due to being open-source, appealing to tight budgets, but self-management can increase total cost. Amazon OpenSearch Service has higher setup costs but justifies them with robust features and managed service benefits. Users report quicker ROI due to reduced operational overhead.

Effective as a vector store, serverless architecture but there aren't enough security features

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. Even being serverless, it incurs charges during idle times. For just holding data, you need to create a list. AWS should add an option to make data idle, so it won't include computing charges. They charge for OCU units based on the time the serverless solution is up, not on indexing or retrieval speed. Once the service starts, it starts getting billed. It would help if there were an option to limit computing. When using it as a database, storing data without frequent fetching would save computing costs.

A very flexible open box that can be used vastly to do anything you need

Make sure that you have dedicated manpower to configure and manage the solution. It requires handling, not necessarily on a daily basis, but it definitely requires someone who is focused and has expertise with the solution. Know in advance what you want to gain from the solution. Don't jump in to configuring or deploying before knowing what you expect from it. I like the solution very much. I think it is a major tool, especially in advanced environments. The open box provides a lot of flexibility and gives a very holistic view of the entire Kubernetes environment. Integrating with the Rancher management tool gives the solution even more abilities. There are several tools that we use behind the scenes to ease the process but the solution on its own is a very good tool. I rate the solution an eight out of ten.

Quotes from Members

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

Pros

"This service already sorts data like vectors. They have classified the storage pre-defined."

"We retrieve historical data with just a click of a button to move it from cold to hot or warm because it's already stored in the backend storage"

"The scalability of Prometheus is very good."

"Stability-wise, I rate the solution a ten out of ten."

"It is a stable solution...Based on the feedback I have received from my colleagues in our company's IT department, the setup phase of the solution is relatively easy."

"It has lots of APIs and libraries to integrate with any kind of language."

"The most valuable features of Prometheus for metrics collection and monitoring are its stability, robustness, and rich set of features."

"The feature I found most valuable is the number of integrations. It is the industry standard for metrics."

"The best thing about Prometheus is its integration."

"Prometheus is a great solution for monitoring."

Cons

"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."

"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."

"I would like to see improvement in the analysis tools and customization features."

"Its stability could be even better."

"The interface is not particularly user-friendly and that could be improved."

"Lacks the ability to clusterize."

"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."

"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."

"Prometheus' UI color can improve. Using the Prometheus UI for configuration or analyzing queries is a horrible experience."

"There isn’t much clarity regarding the issues that happen at the server end. It is a push model and from the client’s point of view, it needs to look better and solve remote issues."
