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…
Sandeep Srirangam - PeerSpot reviewer
Customer engagement & documentation about APIs are great, but it would be good if the UI is a bit more intuitive for search experience
I use the solution mainly to search the logs and to search for VMs by their names or subscription names. I wouldn't rate it great since the logs are a bit complicated The solution was really pretty good. The customer engagement was good. The presented documentation or exposure to the APIs to get…

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 feature of Amazon AWS CloudSearch is the cloud aspect. I do not need to have the physical infrastructure, everything is in the cloud."
"It will remain alive in the market. The solution will be stable in the market."
"The quality of the solution is good."
"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."
"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."
"I've found the solution to be very scalable."
"The best feature is its scalability in that Cloud is always on the fly."
"The product is extremely configurable, allowing you to customize the search experience to suit your needs."
"The amount of flexibility and agility is really assuring."
"The solution's initial setup is straightforward."
"Offers a tremendous amount of flexibility and scalability when integrating with applications."
"The product is pretty resilient."
"Azure Search is well-documented, making it easy to understand and implement."
"Creates indexers to get data from different data sources."
"Because all communication is done via the REST API, data is retrieved quickly in JSON format to reduce overhead and latency.​"
 

Cons

"Security is a concern but they're working on it."
"I do not have any suggestions for improvements at this time."
"The price of the solution can be expensive."
"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."
"Amazon AWS CloudSearch is highly stable. However, the speed depends on your internet connection."
"AWS CloudSearch's documentation isn't very clear. Also, the on-premise version of the solution is less stable than the cloud version."
"Maybe they are common in Egypt, but you should make a request on Amazon to create a function to monitor CPU performance, memory, and files. It is very difficult in AWS. I would tell them it should be simple, just drag and drop. I think they could develop this option so we can drag and drop to monitor performance of the processor and memory."
"They should add an API for third-party vendors, like a security operating center or reporting system, that would be a big improvement."
"The after-hour services are slow."
"It would be good if the site found a better way to filter things based on subscription."
"The pricing is room for improvement."
"For SDKs, Azure Search currently offers solutions for .NET and Python. Additional platforms would be welcomed, especially native iOS and Android solutions for mobile development."
"Adding items to Azure Search using its .NET APIs sometimes throws exceptions."
"The solution's stability could be better."
"For availability, expanding its use to all Azure datacenters would be helpful in increasing awareness and usage of the product.​"
 

Pricing and Cost Advice

"In comparison to IBM and Microsoft, the pricing is more favorable."
"We chose AWS because of its cost and stability."
"Amazon AWS CloudSearch charging is based on how many resources you consume or and the solution is known to be a bit expensive."
"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."
"Our license costs around $4,000 per month."
"There was no license needed to use this solution."
"The cost is comparable."
"The solution is affordable."
"​When telling people about the product, I always encourage them to set up a new service using the free pricing tier. This allows them to learn about the product and its capabilities in a risk-free environment. Depending on their needs, the free tier may be suitable for their projects, however enterprise applications will most likely required a higher, paid tier."
"I would rate the pricing an eight out of ten, where one is the low price, and ten is the high price."
"I think the solution's pricing is ok compared to other cloud devices."
"For the actual costs, I encourage users to view the pricing page on the Azure site for details.​"
