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

"The solution is stable."
"The ability to scale automatically is very valuable. Additionally, multi-region support automatically synchronizing to a different region for multi-region applications is a cool feature. It's more of a lift with other databases to configure that extra region and set up replication, even if it's on the cloud. With Azure, it's just a button click. It's that simple."
"The fact that scalability can be achieved by simply configuring availability zones is very attractive."
"Big data, along with data analysis, is one of the valuable features."
"I definitely recommend Microsoft Azure Cosmos DB."
"The solution is highly scalable."
"Microsoft Azure Cosmos DB's most valuable feature is latency."
"We doubled our productivity with this small application."
"This is the part that should be making admins and CIOs smile."
"The Cloud DRaaS solution provided the organization with new levels of flexibility and cost control, together with rapid expansion capability."
"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."
 

Cons

"Right now, the vectors are stored as floating-point numbers within the NoSQL document, which makes them inefficiently large. This leads to increased storage space requirements, and searching through a vast number of documents in the vector database becomes quite costly in terms of RUs. While the integration works well, the expense associated with it is relatively high. I would really like to see a reduction in costs for their vector search, as it is currently on the expensive side."
"There are multiple approaches to implementing multitenant architecture on Azure Cosmos DB, but there is still no single or best-recommended approach when you have a big variance in the size of your tenants. That is something that still needs to be worked on."
"Cosmos DB should continue evolving in AI features. We expect Cosmos DB to lead on that. There is potential for improved security features, which is important for data storage, especially for Dell Technologies. We must ensure data security remains the top priority."
"There is room for improvement in their customer support services."
"New features can be included and its stability can be further improved."
"Microsoft Azure Cosmos DB's pricing model is complicated, which people don't understand."
"Overall, it is a good resource. I am not aware of the background, but it seems to currently support only JSON documents."
"They can implement a better backup system or alert system on Microsoft's end. We do receive notices for regular maintenance or updates, but sudden issues create significant problems."
"I feel the user interface/portal can be improved further. I did experience timeout issues and the UI was performing slowly at times."
"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."
 

Pricing and Cost Advice

"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."
"There is a licensing fee."
"You need to understand exactly the details of how the pricing works technically to stay within reasonable pricing."
"Its pricing is higher compared to solutions like Aerospike. However, it is justified because of the out-of-the-box features that are provided. The availability and resiliency that we have make it worth the price."
"Azure is a pay as you go subscription."
"Cosmos DB gave us three accounts for $400. We pay according to the usage."
"Its cost is transparent. Pricing depends on the transaction and data size, but overall, it is cheaper compared to hosting it on your corporate network due to other factors like power consumption."
"Cosmos should be cheaper. We actually intend to stop using it in the near future because the price is too high."
