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.

Offers cost-effective log management with strong correlation features across observability tools
Grafana Loki's open-source capability is a significant benefit. Grafana has invested in making their enterprise tools competitive with other APM tools, facilitating cross-correlation with Mimir and Tempo for metrics and tracing. The tool offers good search functionality, and its on-premises capability is advantageous. The indexing performance is strong, making it a robust log management tool. Grafana Loki is notably cost-effective.

Quotes from Members

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

Pros

"The business analytics capabilities are the most important feature it provides."
"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."
"This service already sorts data like vectors. They have classified the storage pre-defined."
"It's a good log management platform. In terms of infrastructure management, it's good."
"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 stability of the product is good."
"Loki significantly saves time in troubleshooting by quickly pinpointing network issues."
"The effectiveness of filters is pivotal for optimizing the search process and extracting the specific information we need from the extensive log data."
"Different types of integrations with various sources are the most helpful and useful features of Grafana Loki that I found for myself."
"Loki also utilizes the same service discovery mechanism as used by Prometheus. So, whatever labeled metadata you see in Prometheus, you have the exact same metadata in the Loki system. Given this level of intricacy and the attempt to address these challenges, I firmly believe that Loki deserves praise for the work."
"Grafana agent is very lightweight and does not cost significant resources of our cluster."
"The solution's stability has never been a problem. Stability-wise, I rate the solution a nine to ten out of ten."
"Grafana Loki's open-source capability is a significant benefit, and Grafana has invested in making their enterprise tools competitive with other APM tools, facilitating cross-correlation with Mimir and Tempo for metrics and tracing."
"The best feature of Grafana Loki is that it integrates well with our other tool."
 

Cons

"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."
"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."
"As a user, lower prices or reasonable pricing is always better."
"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."
"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."
"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."
"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."
"The solution's scalability depends on the team managing the Grafana instance."
"There is a need for some change in the alerting types of the product. In short, a few changes in the alert area are needed due to minor shortcomings."
"We face some bugs when we install the latest version of Grafana Loki."
"My main concern is the recommended production-grade setup. They suggest using tools like Tanka or Jsonnet. They should simplify the process to increase adoption."
"It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers."
"The solution has shortcomings regarding security monitoring-oriented features that need improvement."
"Enhancing speed could be a game-changer, and while it might vary depending on the application, it's a factor worth exploring."
"Improvements could be made in the enablement of the product, addressing the complexity of implementing these tools."
 

Pricing and Cost Advice

"Compared to other cloud platforms, it is manageable and not very expensive."
"The solution is not expensive, but priced averagely, I will say."
"There is a community edition available and the price of the commercial offering is reasonable."
"You only pay for what you use."
"You can use the free version of Grafana Loki on-premises."
"We use a free version."
"Since we are using the open-source version of Grafana Loki, we are not paying anything for the solution."

"My company doesn't need to pay for the licensing cost of the solution."
"I use the solution's open-source version. Grafana Loki is a completely free solution for me."
