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.

Has enabled us to detect issues instantly through alerts and monitor every service from a single dashboard

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

"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."

"In case there is a failure, Elastic manages everything well, and there no major downtime."

"The customer service is excellent, rated nine out of ten."

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

"The stability of the product is good."

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

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

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

More Amazon OpenSearch Service pros

"The features of Splunk AppDynamics that I prefer most are the monitoring aspect, making sure we can drill down and find problems."

"We can see the customer's path from their computer to the backend systems."

"The best feature of AppDynamics is the analytics, which gives us the business insights of the application."

"In my experience, it's easy to use. There's nothing complex to learn or fear. You can quickly adapt to it without the need for extensive training."

"The most valuable feature is the live reporting on the current health\performance of our application"

"Before we moved the code to AppDynamics, we had to compare the agile process and also had to make sure that they're following the standards."

"Provides monitoring more around business processes versus just servers, applications, etc. E.g., with complex systems, where a business process passes across multiple applications, the business needs us to monitor the heath of the process, not just a segment of the application."

"What I like the most about Splunk AppDynamics is the end-to-end observability for the application, along with traces."

More Splunk AppDynamics pros

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."

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

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

"They can enhance data visualization."

"Amazon Elasticsearch can improve the bullion in the near search and the ease of integration with Kibana. Additionally, there could be more flexibility in the configuration and documentation."

"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."

"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."

"The configuration should be more straightforward because we had to select a lot of things."

More Amazon OpenSearch Service cons

"What could be improved in AppDynamics Browser Real-User Monitoring is for the synthetic jobs or synthetic agents, in particular, you can't do a lot of tests with just one agent. You have to install a lot of agents if you want to do more tests, so this is an area for improvement in the solution. Another area for improvement in AppDynamics Browser Real-User Monitoring is that you're only able to see basic metrics in the absence of server or database visibility. For the SaaS version of AppDynamics Browser Real-User Monitoring, my team just downloaded then installed the extension in an application in Azure to see the application on the controller, so if this can be done in the on-premise version of the solution as well, without needing to install the agent on the machine, then it would make AppDynamics Browser Real-User Monitoring better. Currently, the .NET agent consumes the CPU or memory and clients usually raise this issue with my team, so it would be good if the on-premises version doesn't require agent installation on the machine. Another functionality I'd like to see in the next release of AppDynamics Browser Real-User Monitoring is for it to receive updates from the file config without needing to reset IIS because right now when you do a modification in IIS, you have to restart IIS. When you add a service to the agent config, you have to restart IIS. For the product server, it's not possible to reset IIS after you make changes to the config file, so if this could be improved, then it would make AppDynamics Browser Real-User Monitoring a better solution."

"AppDynamics Database Monitoring would be improved with more support for microservices architecture."

"One aspect that requires improvement is the agent. Without an agent, gathering sufficient information on applications is challenging."

"The product lost its place as an industry leader."

"Regarding Search Guard functionality, there is room for improvement."

"The integration ability of AppDynamics with other performance testing tools is an area with shortcomings where improvements are required."

"This feature needs to be properly described to a client, and then the client needs to have a use case. There are some clients which do not need it and some clients who do. It is not for everyone and is dependant on their use case."

"The challenge in the installation is that you have to configure a lot of things manually. The way you install and configure it is not straightforward."

Pricing and Cost Advice

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

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

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

"You only pay for what you use."

"AppDynamics Server Monitoring is an expensive solution."

"This price of this product is expensive."

"We have a license-based solution. That means you need a license for each server you monitor."

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

"We are looking forward to purchasing the solution on the AWS Marketplace."

"The pricing model for AppDynamics could be better. You have to subscribe to a yearly or a three-year licensing, which isn't very handy. The solution is one of the most expensive in the market today."

"It could be cheaper. It's a little cost prohibitive. There are so many features that also show a lot of value, but it’s not always easy to justify the cost."

"AppDynamics Database Monitoring requires a license for database monitoring and other features, while Dynatrace provides monitoring and other features out of the box without additional costs. Sometimes this makes it more challenging to pitch AppDynamics Database Monitoring to customers, especially because you need to buy a separate license. As an implementer, I have yet to learn about the pricing for AppDynamics Database Monitoring. Pricing is taken care of by the sales team."
