CockroachDB's serverless model provides cost-effective, versatile cloud solutions, offering significant savings and operational advantages over separate environments.
Sentiment score
6.3
Azure Cosmos DB users see cost savings and efficiency, especially larger firms, though some report higher expenses and challenges.
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.

You can react quickly and trim down the specs, memory, RAM, storage size, etc. It can save about 20% of the costs.

Room For Improvement

CockroachDB requires improvements in documentation, compatibility, UI features, disaster recovery, latency optimization, integration, and cost efficiency for global deployment.
Azure Cosmos DB's pricing model and integration challenges impact usability, requiring enhanced tools, documentation, and feature improvements.
For multi-region deployment, CockroachDB requires at least three plus replicas across data centers to achieve strong consistency across regions, which increases infrastructure costs including compute, storage, and networking.
Manager, Software Engineering at a tech vendor with 10,001+ employees
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

Setup Cost

Enterprise users find CockroachDB affordable and reliable, with flexible pricing options appealing despite some perceiving high costs.
Azure Cosmos DB offers scalable pricing with dynamic auto-scaling options, requiring RU understanding but offering discounts and enterprise agreements.
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.

Manager, Software Engineering at a tech vendor with 10,001+ employees
Provides developer-friendly environment with robust security and cost-efficiency
The platform should provide a UI feature where users have the ability to manage it. The CockroachDB platform should have a chatbot where users can inquire about pricing or seek solutions for queries, rather than relying on email support. The current UI only provides SQL playground, which is technical. There should be a UI playground where users with limited technical knowledge can run and update queries, similar to phpMyAdmin or Adminer. Latency optimization could be improved for globally distributed applications, particularly in query routing. For multi-region deployment, CockroachDB requires at least three plus replicas across data centers to achieve strong consistency across regions, which increases infrastructure costs including compute, storage, and networking. The disadvantages include cost-efficiency with multi-region deployment and schema migration speed, which should be faster compared to other drivers. The query optimizer should handle complex queries better through the UI interface.

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.
