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.
Gyanesh Rahatekar - PeerSpot reviewer
Application performance management and error resolution improved with data-driven insights
Dynatrace has multiple functions compared to Splunk AppDynamics, so Splunk AppDynamics should add those functions, which are not available as of now. Dynatrace has a universal agent that collects all information related to their CI, and if one CI has multiple languages, then there is no need to instrument multiple agents. However, Splunk AppDynamics requires multiple agents; if I have one server with multiple applications in different languages, then I need to instrument different agents for each application. Splunk AppDynamics should work with Dynatrace with one single universal agent that works with all application languages, eliminating the need for multiple implementations.

Quotes from Members

Pros

"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"
"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."
"Amazon OpenSearch Service has enhanced our organization's ability to store and search large amounts of data efficiently."

"Amazon OpenSearch Service provides a managed database solution, so we don't need to manage everything ourselves."
"The customer service is excellent, rated nine out of ten."
"The business analytics capabilities are the most important feature it provides."

"It is a good monitoring tool. Its stability is very good."
"It is a stable solution that helps address user issues well."
"We can make custom alerts in our system for specific issues like high CPU utilization or application downtime."
"The product is easy to install, it took about half an hour. The use and the configurations are simple as well."
"AppDynamics makes it much easier for us to detect problems or issues before they become problems. We have alerting on all of our business transactions."
"The correlation feature available with AppDynamics Server Monitoring is absent in other competitive solutions"
"We can view the server activities, including issues in the process, with a single click."
"The most valuable features of AppDynamics Database Monitoring are you can configure the performance and see in real-time what is exactly happening with the applications. Additionally, the dashboards are good."
 

Cons

"The price is fair yet leans towards the expensive side. I'd rate it five out of ten with respect to capabilities vs. cost."
"They can enhance data visualization."
"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 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."
"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."
"The networking monitor function could be better, we are not getting many details from it."
"The downside is that it's a little costly."
"If it can be able to intelligently provide all the things we need to look at, from a data point of view, that would be very useful."
"AppDynamics scaled well up to around 3,000 agents. The performance deteriorated after that, while Dynatrace could support more than 10,000 agents. We were surprised that AppDynamics' scalability is not so good."
"AppDynamics is new to the cloud and could improve its cloud services, they are following a monolithic monitoring approach."
"AppDynamics' modules and hardware resources are very high."
"Their support should be improved. Clusters and monitoring can also be improved."
"Splunk AppDynamics provides an end-to-end view of the application but misses the infrastructure part, which is crucial."
 

Pricing and Cost Advice

Information not available
"Take into consideration what you get for specific pricing models and how much it costs to add on things you may need later.​"
"We have two different licensing models for this solution. One of them is the agent based model, which requires payment per agent. The other is an infrastructure based model, where the price is based on the CPU core. For the infrastructure model wholesale level pricing applies. All of the up to date licensing prices for this product are available on the manufacturers website."
"The pricing is quite comparable to similar solutions in the market. All these solutions at the moment are cheap, but it is like paying for insurance; you pay insurance to avoid major damage."
"The way it is structured in terms of price could be better. You pay for individual modules and that adds on to the cost, which detracts you from implementing those modules and slows you down."
"It would be better if there were more solutions incorporated into the base price. ​"
"As a technical person, and as an application development team, they all understand that this is the right tool for us. But when it comes to budget and financial matters, it takes days and weeks to convince upper management to buy this tool. So they should do something more on licensing costs."
"I would like more flexible pricing: A pay-per-use model, rather than just a fixed-price model."
"Pricing is based on the size of the deployment."
