Monitoring microservices has improved and teams respond faster to production incidents

In my opinion, the best features Amazon CloudWatch offers are Metrics, Analytics, Logs, Alarms, Dashboards, and Log Insights, with standout features being real-time monitoring and centralized logging, proactive alerting, and fast troubleshooting. The dashboards in Amazon CloudWatch help with troubleshooting by allowing us to easily look into API latency and how much resource consumption is occurring. The CloudWatch dashboard provides real-time data and views of our application health while Log Insights lets us quickly search and analyze logs to identify root causes of production issues, making troubleshooting time efficient and monitoring much more streamlined. Amazon CloudWatch has positively impacted my organization by improving our ability to monitor production issues and easily find the root cause in the application. We can quickly fix issues at the point of occurrence, and real-time metrics for microservices provide centralized logging and automated alerts that enable fast incident detection, quicker troubleshooting, and better application reliability, ultimately reducing operational efforts by giving engineers a single platform for monitoring AWS resources and microservices. I have seen many positive outcomes in my organization, estimating that CloudWatch reduced troubleshooting time by around thirty to forty percent because engineers could correlate metrics and logging from a single platform. Early alerts also help us resolve many performance issues before they escalate into major incidents, contributing to improved service availability.

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.

"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."

"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."

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

"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."

"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 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."

More Amazon OpenSearch Service cons
