Review summaries and opinions

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

ROI

Sentiment score
6.2
Organizations report cost savings and efficiency with Azure Cosmos DB, but some experience complexity and difficulty achieving expected savings.
Sentiment score
4.8
Supabase Vector cuts costs and development time, offering startups and companies efficient, cost-effective deployment and technological advantages.
Getting an MVP of that project would have taken six to eight months, but because we had an active choice of using Azure Cosmos DB and other related cloud-native services of Azure, we were able to get to an MVP stage in a matter of weeks, which is six weeks.
Director | Data & AI at a tech services company with 11-50 employees
You can react quickly and trim down the specs, memory, RAM, storage size, etc. It can save about 20% of the costs.
Co-Founder at arpa
When I have done comparisons or cost calculations, I have sometimes personally seen as much as 25% to 30% savings.
Solutions Architect at CompuNet
The dashboard's management made access straightforward for users and super easy to maintain, resulting in very few errors.
Co-Founder & CTO at Mango Giraffe
The use of these technologies definitely impacts reducing the time and cost of implementation or deployment.

Room For Improvement

Microsoft Azure Cosmos DB needs improvements in query complexity, API integration, performance, documentation, cost management, and user-interface enhancements.
Users face challenges with Supabase due to limited support, complex setup, scaling issues, and insufficient documentation and features.
We must ensure data security remains the top priority.
Cloud Solutions Architect and Microsoft Principal Consultant for EMEA at a tech vendor with 10,001+ employees

When I'm in Supabase Vector, there is a feature where I have to create a table. At the start, for newcomers, it's difficult, and then it becomes hard.
Software Developer at a performing arts with 1-10 employees
I wish that there was a convenient way to make it compatible with the general Postgres database SDK.
Director at a tech services company with 1-10 employees
An improvement for Supabase Vector would be to have it enabled by default.
Co-Founder & CTO at Mango Giraffe
 

Setup Cost

Azure Cosmos DB pricing varies, appreciated for scalability but seen as costly with high demand and complex environments.
Supabase Vector's enterprise pricing varies, with standard plans at $480/year, and free trials available for basic implementation.
Initially, it seemed like an expensive way to manage a NoSQL data store, but so many improvements that have been made to the platform have made it cost-effective.
Lead Cloud Architect at Solliance, Inc
Cosmos DB is expensive, and the RU-based pricing model is confusing.
IT Data Architect & Manager at Ternium Mexico S.A. de C.V.
Cosmos DB is great compared to other databases because we can reduce the cost while doing the same things.
Lead Software Architect at CPower
It was amazing to be able to create all this technology for free, without the need to pay additional costs to use those technologies, apart from the embeddings ones from Google.
Co-Founder
The price is good.
Founder at a tech services company with 1-10 employees
 

Valuable Features

Microsoft Azure Cosmos DB is valued for scalability, ease of integration, global distribution, security, and support for diverse applications.
Supabase Vector offers a unified platform combining relational and vector data with seamless setup, security, and efficient management.
The most valuable feature of Microsoft Azure Cosmos DB is its real-time analytics capabilities, which allow for turnaround times in milliseconds.
Vice President, Machine Learning at a healthcare company with 10,001+ employees
Performance and security are valuable features, particularly when using Cosmos DB for MongoDB emulation and NoSQL.
IT Data Architect & Manager at Ternium Mexico S.A. de C.V.
The performance and scaling capabilities of Cosmos DB are excellent, allowing it to handle large workloads compared to other services such as Azure AI Search.
CTO at Stellium Consulting
We have Supabase basically as the host of most of our business relational database and user data, so since the client's applications are migrating to language model-empowered features, it is very useful, and we do not need to register for other database types.
Director at a tech services company with 1-10 employees
Supabase Vector is a managed service, so I do not need to worry about scaling the database and managing the infrastructure.
Senior Full Stack Engineer at a tech vendor with 11-50 employees

Collecting compliance data has become more efficient while managing unstructured inputs for reporting
The features that I find most valuable within Microsoft Azure Cosmos DB are probably the cost, as the cost optimization is good. The storage and queryability are good for what we're doing; it's a lot of unstructured data, so having a platform to put that in and then be able to harvest that data out for the reporting we do is essential. In terms of cost saving, it was probably easily 30 to 40% cheaper than doing a standard SQL, which is what we saw just on piloting and getting in there. We were initially thinking 20 to 25%, but we were probably more at the 35 to 40%. We are using Microsoft Azure Cosmos DB's hybrid search today. The value that it has added to my AI or search workloads is that I think it's optimized that process and made it easier. We have a lot of unstructured data coming from different dissimilar systems and different data sources, so correlating those things together and making sense of it has been very beneficial. Microsoft Azure Cosmos DB has had pretty good performance with searching through large amounts of data; it's been fast, and we haven't seen a lot of performance degradation while building larger queries and bringing in a large set of data. The dynamic auto-scale or serverless model from Microsoft Azure Cosmos DB has helped reduce costs and operational effort; however, it's hard to quantify how that plays out since you're using a shared service. It shifts my focus away from building, managing, and upgrading to adding value.

Vector search has reduced duplicate citizen proposals and empowers richer democratic participation
I had problems integrating the vector directly into Supabase, so I had to use Google Vertex to generate the embeddings and the information I needed in the database. It would be nice if all of this could be integrated all in one place with Supabase. I would prefer not to have to use a different or external tool to create these embeddings. It would be nice to have everything integrated in the same way. Apart from that, I think that is one of the cons I found, but it is basic. That was my main concern in that regard. My advice for others looking into using Supabase Vector is to take into account how you are going to create the embeddings, as it is not an option implemented straight away in Supabase. You will need to handle the embeddings with an external tool, so make sure to consider how these integrations are going to be made.
