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

"Switching to the cloud significantly improved scalability, flexibility, and uptime."
"Their new feature, dynamic data masking, is very cool and useful for us."
"The solution is highly scalable."
"Reading and inserting data into Microsoft Azure Cosmos DB is a very smooth process."
"The solution is scalable, and we intend to increase our usage."
"With Azure you can start small and grow as you need."
"Cosmos DB is a document database that stores data in JSON format for faster retrieval of unstructured data. I personally appreciate the speed, which is significantly better for unstructured data, especially since Cosmos DB had JSON as a data type early on."
"Our customer is very satisfied with it."
"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."
"This is the part that should be making admins and CIOs smile."
 

Cons

"A further simple application is required for Brazil."
"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."
"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."
"We should have more freedom to tweak it and make our own queries for non-traditional use-cases."
"At this stage, we would like more enterprise support. We use MongoDB a lot, and we're trying to get rid of MongoDB. So, I would like to see more features in the Cosmos DB API for MongoDB space."
"For streaming platforms, Azure Cosmos DB could improve efficiency in data storage. Indexing can also be better. Enhanced capabilities are necessary to manage increased data amounts more effectively during searches."
"We had to go to forums to check if it was failing for everyone else. It was surprising that a large organization like Microsoft doesn't provide an official statement about the maintenance or issues that could impact our overall usage."
"A minor improvement would be enabling batch operations through the UI. Currently, to delete all documents in a collection, we must use an API, which some of my team finds inconvenient for admin tasks."
"I feel the user interface/portal can be improved further. I did experience timeout issues and the UI was performing slowly at times."
"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."
"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."
 

Pricing and Cost Advice

"The customer had a high budget, but it turned out to be a little bit cheaper than what they expected. I am not sure how much they have spent so far, but they are satisfied with the pricing."
"Everything could always be cheaper. I like that Cosmos DB allows us to auto-scale instead of pre-provisioning a certain capacity. It automatically scales to the demand, so we only pay for what we consume."
"We are not consuming so much yet since we are at the beginning of using this solution. I would rate the pricing of Microsoft Azure Cosmos DB a six out of ten."
"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."
"With heavy use, like a large-scale IoT implementation, you could easily hit a quarter of a million dollars a month in Azure charges if Cosmos DB is a big part of it."
"For the cloud, we don't pay for the license, but for the on-prem versions, we do pay."
"The pricing model of Microsoft Azure Cosmos DB is a bit complex."
"There is a licensing fee."
