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.

With the VPC, you can run your workloads in an active state, use it for development work and for hosting SQL/Exchange Servers in IaaS; RaaS/DaaS for DR activities.
All three components of the vCloud Air are equally valuable and important, i.e., IaaS, DaaS and RaaS. I like the Virtual Private Cloud (VPC) offering compared to the Dedicated Cloud. It gives me the flexibility to utilize the pay-as-you-go option. You can run your workloads in an active state at reasonable prices. I have seen lots of companies use it for their development work, as well as for hosting SQL and Exchange Servers, i.e., in the active-passive mode instead of Replication (RaaS). Disaster Recovery is also a great feature that is affordable and easy to use. Disaster Recovery is a great component of the vCloud Air, where you can protect the on-premises cloud infrastructure, by providing self-service recovery options using the vSphere Replication. Some of the features that really stand out and I have used in my projects are: * Direct Connect: It provides high speed and private line connectivity. * Offline Data Transfer: For encrypted bulk data transport.

Quotes from Members

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

Pros

"What I appreciate most are the latency and the access, which are guaranteed by the tool, which is really impressive."
"The best features of Microsoft Azure Cosmos DB include the speed to query data; as long as you index properly, retrieving data is fast and lightweight."
"Azure Cosmos DB's resiliency is valuable. It is available in every Azure region, allowing quick information storage and retrieval. We can partition it to improve indexing, enabling us to retrieve information and recreate website content quickly."
"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."
"The best feature is the velocity to make a query."
"Cosmos DB is a pretty stable solution. I would rate it a ten out of ten."
"The product has a lot of useful features that are there and ready to use, it's also very easy to use."
"Some of the best features of Microsoft Azure Cosmos DB are that it could scale, and we could still use SQL language."
"This is the part that should be making admins and CIOs smile."
"VMware Workstation has an interesting feature to manage vSphere infrastructure (and also stand-alone ESXi hosts) that is really powerful and useful, for example to avoid to install the vSphere client (or the integration plugin) just to open one VM console or to change the power status for some VM."
"The Cloud DRaaS solution provided the organization with new levels of flexibility and cost control, together with rapid expansion capability."
 

Cons

"An improvement could include increasing the document size or providing a method to manage larger sets efficiently. If they want to keep a 2 MB limit, they should provide a way to chain multiple documents in a systematic way so that developers do not have to figure out what to do when a document is larger than 2 MB."
"The integration with other solutions needs to improve because Cosmos DB's interoperability is lacking in some scenarios. For example, I'm currently implementing Fabric. That involves migrating from environments without apps, processing data and users, and taking them to Fabric."
"From about half a billion rows, we're returning maybe 20,000 in two or three minutes. We don't know why, but we are working with Microsoft and a third party to figure that out."
"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."
"I would like to see Cosmos DB introduce a feature that would convert machine language to human-readable queries."
"Azure Cosmos DB is generally a costly resource compared to other Azure resources. It comes with a high cost."
"Currently, it doesn't support cross-container joins, forcing developers to retrieve data from each container separately and combine it using methods like LINQ queries."
"A way Microsoft Azure Cosmos DB could be improved is through the introduction of an access control list on a row and on a specific field within the document, rather than relying on application-level coding to manage different access control lists."
"It’s a really good idea, but the current implementation is very limited: you can simply see your VMs and just open the VM console."
"I don’t think it is quite where EC2 is with regard to capabilities and features but VMware is investing a lot in vCloud Air."
"I feel the user interface/portal can be improved further. I did experience timeout issues and the UI was performing slowly at times."
 

Pricing and Cost Advice

"I would rate Cosmos DB's cost at seven out of ten, with ten being the highest."
"You need to understand exactly the details of how the pricing works technically to stay within reasonable pricing."
"Most customers like the flexibility of the pricing model, and it has not been an issue. They can start small, and the cost grows with adoption, allowing efficient management of the budget. Its pricing model has not been a concern at all for any of our customers. They understand it. It is simple enough to understand. Oftentimes, it is hard to forecast the RUs, but, in general, it has been fine."
"It is expensive. The moment you have high availability options and they are mixed with the type of multitenant architecture you use, the pricing is on the higher end."
"Microsoft Azure Cosmos DB pricing is based on RUs. Reading 1 KB document costs one RU, whereas writing one document costs five RUs. Pricing for querying depends on the complexity of the query. If you increase the document size, it will automatically increase the RU cost."
"The Cosmos DB pricing model, initially quite complicated, became clear after consulting with Azure Advisor, allowing us to proceed with confidence."
"For the cloud, we don't pay for the license, but for the on-prem versions, we do pay."
"The pricing for Microsoft Azure Cosmos DB is good. 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."
