Event tracking has become smoother and data analytics provide clear insights for user actions

Amazon OpenSearch Service is not providing the processing feature directly. From Amazon OpenSearch Service, we are actually maintaining the AWS SQS, the queue service, which is responsible for providing information about what data has to be modified. So using that SQS, we're actually providing it, but we're not directly using Amazon OpenSearch Service for keeping data to other data pipeline thing. So far we didn't use it for any machine learning purposes, but in future, we have plans to extend or implement this feature. Since AWS itself is secure and Amazon OpenSearch Service is a part of this entire ecosystem, it becomes much easier for security purposes. From the validation point of view, Amazon OpenSearch Service itself provides easy to communicate APIs and up-to-date documents, which is much beneficial. For example, if I'm missing anything, I can directly go and check the documentation. That is actually much easier. I would rate it as really good so far. It's much faster. For our local machine, we can also use a kind of replica of Amazon OpenSearch Service just for development purposes. That is another good feature. I would say for the encryption thing and also the user access control management, it's much faster. For some of these hashing algorithms, it also worked really well so far. To be honest, I didn't find any places where it can be improved. However, I think they could provide more abstraction. For example, still for searching, we have to write down the queries in a specific manner, such as for a specific JSON structure or in a specific way. Otherwise, they don't provide us the actual results. For at least this purpose, I think abstraction could be a bit easier or a bit improved. Other than that, right now there is the age of AI, so some kind of prompting could also work, but I'm not sure how it could be integrated. As a user, lower prices or reasonable pricing is always better. Those can be improved as well. However, it is good that most of the services including Amazon OpenSearch Service actually provide pay as you go pricing. So if there were a bit lower version or a bit less payment methodology, it might be much better.

Splunk requires significantly more improvements compared to Splunk AppDynamics, specifically regarding the licensing aspect. Splunk renews licenses every six months, which is inconvenient. It would be better to have a one-year license to avoid needing to update keys constantly, which can only occur on weekends, making it a burdensome task. Although Splunk is better for certain use cases, Splunk AppDynamics is broader in functionality. Specifically, I want enhancements related to creating dashboards not only for logs or minor services but also for configuration levels, allowing us to check configurations immediately without manually opening the entire code when exceptions arise—a feature I wish to see improved in Splunk, although it may not be necessary for Splunk AppDynamics.

Quotes from Members

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

Pros

"It's a good log management platform. In terms of infrastructure management, it's good."

"The business analytics capabilities are the most important feature it provides."

"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"

"Amazon OpenSearch Service provides a managed database solution, so we don't need to manage everything ourselves."

"I would definitely recommend Amazon OpenSearch Service to other professionals due to its fast and reliable search capabilities."

"The stability of the product is good."

"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."

"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."

More Amazon OpenSearch Service pros

"The product provides a nice end-user experience."

"There are many features that are very valuable to us, but the ability to monitor the status of the users' experience in real-time is one of them."

"It has improved our organization with its ability to catch issues quickly and fix them."

"This solution is easy to use and very powerful, it is a complete tool for us."

"AppDynamics is easy to implement if you follow the documentation, and the documentation that they provide is good."

"The solution saves time and cost."

"The features that I like best are the dashboard and Business Journey."

More Splunk AppDynamics pros

Cons

"I want to see a new feature in Amazon Elasticsearch Service that allows users to create default filters for filtered levels."

"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."

"As a user, lower prices or reasonable pricing is always better."

"One improvement I would like to see is support for auto-scaling."

"The price is fair yet leans towards the expensive side. I'd rate it five out of ten with respect to capabilities vs. cost."

"One improvement I would like to see is support for auto-scaling."

"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."

More Amazon OpenSearch Service cons

"The solution could be more user-friendly for diagnostic purposes. Anyone who is using the solution should be able to infer what that error is about, they should be able to troubleshoot it better."

"The only improvement I see is intercepting calls in a mobile application without injecting additional code. Currently, when instrumenting or monitoring a mobile application, it's necessary to release updates, prompt users to upgrade, and inject code into the backend. It would be beneficial if there were a method to intercept these calls without requiring users to download and upgrade the application. However, I'm unsure about the feasibility of such an approach."

"The resolution time takes longer than expected."

"If we consider the implementation of alternative solutions, such as Dynatrace, there is a notable difference in the approach to agent-based service monitoring. For instance, Dynatrace employs a single-agent solution, which can pose security concerns. When installing Dynatrace, granting the agent ld pro payload rights is a requirement. In contrast, our solution ensures a more secure approach by not requiring root and administration access. While we currently utilize an agent-based solution, there may be a shift in the next one or two years, possibly with the adoption of Open Telemetry. It's anticipated that many APM vendors, including Dynatrace, may alter their structure or strategy for implementation. However, as of now, the trend is towards an increasing number of implementations daily."

"I would like to see something that lets me set real dollar figures, not just to outages, but to the solutions as well... when I'm looking at problems and have found a problem that I know I need to address. I could flag it off and have AppDynamics estimate how long a person would have taken to find that without it. That would give me a lot of leverage for justifying the existence of APM, which I really need."

"The scalability could be improved."

"We would like to be able to easily use this solution to monitor our Java script based browsers, which are currently blocked by the security settings."

"The solution’s setup is a bit complex."

Pricing and Cost Advice

"The solution is not expensive, but priced averagely, I will say."

"You only pay for what you use."

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

"There is a community edition available and the price of the commercial offering is reasonable."

"AppDynamics is more expensive than competitors."

"There is a license needed to use the solution and it is expensive. The licensing model needs to improve."

"I was not involved with the procurement of AppDynamic, but I believe it's expensive."

"The licensing scheme is very complex. They need to make it easier."

"I would say the solution is affordable because it is widely used across financial service sectors."

"Yearly payments have to be made toward the licensing costs of the solution. The solution has no additional costs apart from the licensing costs."

"The product is a bit expensive compared to other tools."

"This price of this product is expensive."
