A scalable and fully managed search service with diverse data type support and robust security
We use it as our hosting solution, serving as the backbone for our systems, which include Rubrik and SAP It is remarkably efficient and beneficial. A reboot should be enhanced. There are issues with the VBC collection. I have been working with it for four years. I would rate the stability ten…
Johnny Suleiman - PeerSpot reviewer
Scalability is a key feature as it allows easy scaling of the platform without downtime
OpenSearch is used as a search engine for specific logs, mainly in e-commerce and monitoring the logs themselves. It is very valuable for e-commerce, enabling data analysis on application logs and customer behavior, and can be integrated with other services, including AI and machine learning…

Quotes from Members

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

Pros

"AWS CloudSearch's best features are good performance under high CPU and memory use, and ease of deployment and scaling."
"The initial setup is straightforward."
"The most valuable feature of Amazon AWS CloudSearch is its ability to receive data quickly. You can access your data easily in a short time."
"It will remain alive in the market. The solution will be stable in the market."
"It is remarkably efficient and beneficial."
"It's the best solution for any company. It has a hosting ERP system for any task. AWS is stable. AWS is more flexible and its elastic concept is a new concept. AWS is also very secure. It has many layers of security, like hardware security and software security. This is a big issue."
"Document indexing, text-based search API, and Geospatial searches are all good features."
"I've found the solution to be very scalable."
"In case there is a failure, Elastic manages everything well, and there no major downtime."
"Amazon OpenSearch Service has enhanced our organization's ability to store and search large amounts of data efficiently."
"Amazon OpenSearch Service provides a managed database solution, so we don't need to manage everything ourselves."
"The business analytics capabilities are the most important feature it provides."
"The customer service is excellent, rated nine out of ten."
"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."
"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."
 

Cons

"Security is a concern but they're working on it."
"Index cleanup is sometimes painful. No easy way to clean indexes or a bulk of documents. Full indexing or regeneration of entire indexes sometimes gets stuck. In one instance, we had to delete the entire index and re-create it."
"Regarding the period of propagation on CDN servers, sometimes we update photos or files and we don't see the update instantly. We need to wait for sometime."
"The solution should improve the recovery aspects that it has on offer."
"Latlon data type only supports single value per document. All other types support multiple values. We faced issues with this because we had scenarios where, for each document, we needed to store multiple latlon values for different geographical locations."
"AWS CloudSearch's documentation isn't very clear. Also, the on-premise version of the solution is less stable than the cloud version."
"The price of the solution can be expensive."
"A reboot should be enhanced."
"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."
"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 price is fair yet leans towards the expensive side. I'd rate it five out of ten with respect to capabilities vs. cost."
"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."
"One improvement I would like to see is support for auto-scaling."
"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."
"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."
 

Pricing and Cost Advice

"In comparison to IBM and Microsoft, the pricing is more favorable."
"Amazon AWS CloudSearch charging is based on how many resources you consume or and the solution is known to be a bit expensive."
"Our license costs around $4,000 per month."
"On a scale of one to ten, where one point is cheap, and ten points are expensive, I rate the pricing as medium or reasonable."
"I'm not sure how much we pay a year. It might be around $30,000 a year."
"There was no license needed to use this solution."
"We chose AWS because of its cost and stability."
"You only pay for what you use."
"The solution is not expensive, but priced averagely, I will say."
"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."
