A reasonably priced solution that provides scalability, stability, reliability, and security

In terms of what needs improvement, I would say that it needs to keep its cost competitive in the market, especially in comparison to other clouds. Let's say we have various clouds in the market, like Google Cloud, Oracle Cloud, and AWS Cloud. However, security-wise, I don't think AWS is bad. It's good only, especially in comparison to Oracle Cloud, if you really use Oracle, while also considering the fact that PeopleSoft is an Oracle product. AWS is a separate cloud, and Oracle has its own cloud. If you are in a new PeopleSoft and Oracle and you are using a third-party cloud, it means it is not easy since we can't think it is easy. I mean, if you are using Oracle products and you are using Oracle Cloud, it will be easier for you. However, it has a cost in comparison to AWS. Oracle Cloud is too costly. According to region, we segregate because it depends on the organization's strength. Let's say your organization has 1,000 customers. In that case, on a daily basis, let's say one customer was released or discontinued using the product. Then, you have to remove the solution. However, if you use Oracle Cloud, that space will remain there. In the case of AWS, they will immediately cut down their space, meaning in terms of reuse ability, it will reduce the cost. In our case, AWS is the best in the market, actually. We have various clouds like Google Cloud and Microsoft Azure Cloud, the features of which are very different. There are a lot of features in AWS Cloud since I am not in the market providing service on the products. I am just using that tool to access our clients' database and deliver our day-to-day service. I interact with the clients regarding their issues, whatever they are facing. There is this one kind of interface we use to access things because they are in AWS Cloud. If your customer is in Oracle Cloud, then there will be a different approach to accessing it. In our case, we can use AWS or Oracle, so it doesn't matter to us.

Automated indexing has streamlined document search workflows but semantic relevance and setup complexity still need improvement

We used the semantic search capabilities of Azure AI Search, but we haven't gotten good results in the semantic search. So we are exploring with ChromaDB, and Cosmos is having the capability of doing the semantic search as well. We are exploring that. A few queries we use analytics search, which works and is good. Analytics search is good. We are trying the ML capabilities of the product since we are using Databricks and other tools for building the models, MLflow, and related items. We are still working on proof of concepts, which could be better with ChromaDB or Cosmos or vector search or inbuilt Databricks vector stores. Language processing is not about user intention; it's about the context. If there is a document and you want to know the context of a particular section, then we would use vector search. Instead of traversing through the whole document, while chunking it into the vector, we'll categorize and chunk, and then we'll look only at those chunks to do a semantic search. When comparing Azure AI Search, I'm doing a proof of concept because with ChromaDB I can create instances using LangChain anywhere. For per session, I can create one ChromaDB and can remove it, which is really useful for proof of concepts. Instead of creating an Azure AI Search instance and doing that there, that is one advantage I'm seeing for the proof of concept alone, not for the entire product. I hope it should support all the embedding providers as well. Is there a viewer or tool similar to Storage Explorer? We are basically SQL-centric people, so we used to find Cosmos DB very quick for us when we search something and create indexes. I guess there is some limitation in Azure AI Search. I couldn't remember now, such as querying limitations. I'm not remembering that part.

Quotes from Members

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

Pros

"In our case, AWS is the best in the market, actually."

"It is remarkably efficient and beneficial."

"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."

"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, more flexible with its elastic concept, and also very secure with many layers of hardware and software security."

"I've found the solution to be very scalable."

"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."

"AWS CloudSearch's best features are good performance under high CPU and memory use, and ease of deployment and scaling."

More Amazon AWS CloudSearch pros

"Creates indexers to get data from different data sources."

"The features in Azure AI Search that are most valuable include the ability to automate index creation, and you can drop in the blob storage or drop in the SQL table, which will get automatically indexed."

"It provides good access capabilities to various platforms."

"Offers a tremendous amount of flexibility and scalability when integrating with applications."

"The customer engagement was good."

"Usually, that search functionality used to take around 10 secs to search data, and that time has been reduced to a few milliseconds now."

"The solution's initial setup is straightforward."

More Azure AI Search pros

Cons

"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."

"We'd like to see more database features."

"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."

"In terms of what needs improvement, I would say that it needs to keep its cost competitive in the market, especially in comparison to other clouds."

"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."

"Security is a concern but they're working on it."

"Amazon AWS CloudSearch is highly stable. However, the speed depends on your internet connection."

"Amazon's technical support needs to improve as they only solve about half our problems."

More Amazon AWS CloudSearch cons

"The pricing is room for improvement."

"Adding items to Azure Search using its .NET APIs sometimes throws exceptions."

"The initial setup is not as easy as it should be."

"The after-hour services are slow."

"Adding items to Azure Search using its .NET APIs sometimes throws exceptions."

"On a scale from one to ten where one is the worst and ten is the best, I would rate Azure Search as probably a six-out-of-ten."

"We used the semantic search capabilities of Azure AI Search, but we haven't gotten good results in the semantic search."

"It would be good if the site found a better way to filter things based on subscription."

More Azure AI Search cons

Pricing and Cost Advice

"Our license costs around $4,000 per month."

"Amazon AWS CloudSearch charging is based on how many resources you consume or and the solution is known to be a bit expensive."

"We chose AWS because of its cost and stability."

"There was no license needed to use this solution."

"In comparison to IBM and Microsoft, the pricing is more favorable."

"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."

"The solution is affordable."

"For the actual costs, I encourage users to view the pricing page on the Azure site for details."

"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."

"The cost is comparable."

"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."
