Managed database service has simplified hybrid integration and strengthened automated backups
The only red flag I could point out is you don't have 100% control of your data. You don't have 100% control of that particular server because it is Microsoft that has access to it. For instance, if you are working with a government organization that doesn't want their data to be resided outside the country, it will not work. You cannot use it because there's no way the data is going to be resided somewhere outside a particular country. Let's say for instance, I'm having an engagement with a Lagos state government with a particular product that need to be deployed and then I can never propose such kind of environment for them because Lagos state will never allow their data to be resided elsewhere except within their data center. In that case, you can't use it. Technology evolves every day and then as technology moves, I move as well. Currently, with what I'm seeing on Azure SQL Managed Instance, it's somewhat perfect, but they still need to do more. But if I'm going to probably figure out what could be the added features within the environment, maybe probably the SA admin should be released to the users within the SQL infrastructure team, SQL team, that is the database team members. Because currently, nobody has access to the SQL admin. The SA admin is one of the greatest accounts. Although Microsoft put a provision for that, your Active Directory account can perform the same function that SA admin can do, because you're not running the SQL within your own VM or physical server. Microsoft controls that. Aside from that, because to me, I don't even see it as a problem because there's a provision for that. In the absence of that SA admin, your Active Directory account can be probably elevated to perform the same function. I don't see anything that's probably against it.

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.

Quotes from Members

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

Pros

"Security-wise, Azure SQL Managed Instance is absolutely robust, and governance-wise, the manageability of Azure SQL Managed Instance is very good."
"I can tell you categorically that the ROI, the return on investment is very, very high and it's very commendable."
"Cosmos DB has helped us by providing faster response times for everything, which significantly improved our search results quality."
"For example, we have people spread across multiple locations; if they update data in Australia, we can access it in another location within a fraction of a second."
"Change notification works well, and the ability to process documents in a scalable way is important. This means we can efficiently thread out different operations and meet our organizational performance and scalability needs."
"Since it's a managed service, Azure backend handles scalability. From a user's perspective, we don't need to worry about scalability."
"Cosmos DB is stable and easy to use."
"I would rate Microsoft Azure Cosmos DB a ten out of ten."
"Microsoft Azure Cosmos DB helped improve our organization's search result quality significantly when we started using it about eight years ago."
"Cosmos DB performs exceptionally well and has not caused any issues that necessitate adjustments in nodes for improved performance."
 

Cons

"The only red flag I could point out is you don't have 100% control of your data. You don't have 100% control of that particular server because it is Microsoft that has access to it."
"Azure SQL Managed Instance can be improved by adding more scalability options."
"A limitation in Azure Cosmos DB is the 2 MB document size. Developers need more systemic support in chaining multiple documents if more than 2 MB is required."
"I think Microsoft Azure Cosmos DB can be improved by providing continuous backup for multi-region rights. I believe it's available for non-multi-region rights, but there are many features that are locked behind continuous backup that I can't use because it's not enabled yet."
"I think it could be better if it included more in regards to AI or if it were more exposed to AI."
"The pricing of the solution is an area with certain shortcomings."
"The UI should be improved since if you provide the option to query directly when signing into the Azure portal, it makes no sense if you have such a poor UI for querying that you can't even feed the reports correctly."
"Overall, it works very well and fits the purpose regardless of the target application. However, by default, there is a threshold to accommodate bulk or large requests. You have to monitor the Request Units. If you need more data for a particular query, you need to increase the Request Units."
"The RUs still appear to be a black box for everyone. Even though they explain read and write RUs, it remains unclear for many users."
"There's a little bit of a learning curve because I was new to Azure. But once you learn the tool, it's pretty straightforward."
 

Pricing and Cost Advice

Information not available
"The pricing model of Microsoft Azure Cosmos DB is a bit complex."
"Pricing, at times, is not super clear because they use the request unit (RU) model. To manage not just Azure Cosmos DB but what you are receiving for the dollars paid is not easy. It is very abstract. They could do a better job of connecting Azure Cosmos DB with the value or some variation of that."
"Cosmos DB is expensive, and the RU-based pricing model is confusing. Although they have a serverless layer, there are deficiencies in what I can define and assign to a database. Estimating infrastructure needs is not straightforward, making it challenging to manage costs."
"You need to understand exactly the details of how the pricing works technically to stay within reasonable pricing."
"Cosmos DB gave us three accounts for $400. We pay according to the usage."
"Azure Cosmos DB's pricing is competitive, though there is a need for more personalized pricing models to accommodate small applications without incurring high charges. A suggestion is to implement dynamically adjustable pricing that accounts for various user needs."
"Cosmos DB is cost-effective when starting but requires careful management."
"This cost model is beneficial because it allows for cost control by limiting resource units (RUs), which is ideal. However, for our needs, we can't engage with their minimum pricing, which ranges from 100 to 1,000 RUs. At the bare minimum, we need to use 4,000 RUs for a customer. I would like to find a way to gain some advantages from the lowest tier, particularly the ability to scale down if necessary. It would be helpful to have more flexibility in cost management at the lower end."
