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.

Real-time monitoring has improved our banking API performance and supports detailed business transaction analysis

The real-time monitoring is what we can see for anything that is needed in terms of CPU, memory, or the connections or the sessions related. It's real-time monitoring of performance of each of the components, which is what we need and use all the time. It's highly effective, I would say. Infrastructure visibility, transaction monitoring, to check the actual user experience in terms of the response time, MRT and all those things. We do the component monitoring like the API performance and the connections and all those things, but we also do the business process monitoring and business transaction monitoring.

Quotes from Members

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

Pros

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

"It's actually easier to collaborate since it is already deployed in the AWS cloud itself."

"It enables us to efficiently search and retrieve our event data, offering us a versatile approach to locate specific information within these logs."

"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."

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

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

"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."

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

More Amazon OpenSearch Service pros

"I like how the AppDynamics dashboard portrays the information flows. When a task is executed, various flows between different applications and databases happen in the background. The dashboard is intuitive and helps visualize the connections, the directions of the flow, and the information related to these specific sessions."

"Application Analytics reduces the average time it takes to repair performance problems and improves cooperation between different IT departments."

"We have used technical support many times, we have created so many tickets, and they're really good; the response is really very fast, which is the one thing I like about the tech support."

"The solution's most valuable feature is the response time from the end-to-end server."

"With the metrics AppDynamics provides us with, we have a complete picture to draw conclusions."

"It provides everything into one view, so we can track information from one place to another."

"If I compare AppDynamics Server Monitoring with JVM-based applications, it is a pretty good tool."

"Capacity planning is, in my opinion, the most useful."

More Splunk AppDynamics pros

Cons

"There is the problem with the database. Amazon only provides the host to run to our applications bias, but there is no option to manage the database within the Elasticsearch product."

"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."

"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."

"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."

"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."

"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."

"They can enhance data visualization."

More Amazon OpenSearch Service cons

"Scalability-wise, I think it's a little limited on an enterprise-wide scale."

"In the transaction naming features, for business transactions, we are not always able to tie a business transaction to a real user transaction."

"It does not support network monitoring, which should be included."

"It could be more user-friendly for beginners."

"Unfortunately, the setup is quite expensive, which is the bad part of it because I want to spread my agent across the IT landscape, but that's very expensive."

"The biggest complaint that we have at this point is the ability to exclude certain time frames from the dynamic baselining."

"A few things genuinely frustrate me about Splunk AppDynamics. First, the UI, while powerful, is dense and not modern compared to products like DataDog or New Relic, requiring a learning curve for new team members."

"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."

More Splunk AppDynamics cons

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."

"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."

"It is not a cheap tool, but you also save in manpower to setup because it is easy and fast. At the end of the day, I think the revenue is much better. BUT, they have an awful co-term mode of licensing."

"We do not have any issues with the price."

"It's a very expensive product. Each of the licenses after this month for one server is around $9,000 or $10,000."

"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."

"I rate AppDynamics Mobile Real-User Monitoring's pricing as seven out of ten. Mobile monitoring is paid based on the number of instances utilizing the mobile monitoring service, which increases as the scale grows. Consequently, your mobile user count can proportionally surpass all other applications."

"In terms of pricing, I feel that when you compare the benefits that we get to the price that we paid, it is reasonable."

"The product’s licencing policy is competitive. However, properly identify and size your needs to get the best rate."
