Data platform has transformed analytics and now provides seamless storage and insight on user behavior
Microsoft Azure HorizonDB scales perfectly. It automatically scales whenever there is a load on the application. I have configured the deployment files on my projects, and the database is able to handle automatic scaling by itself, so I do not have to put much attention on that aspect. It scales down automatically as well. I monitored the scaling and scaling out one or two times during the initial stage when I was first including this database in my project. After the first and second times, I checked only the logs for automatic scaling and scaling out. I have not encountered any issue on the scaling side, and it provides consistent performance for both scaling and scaling out.

Positive experience with virtual cloud network creation and database migration highlights patching challenges
The best feature of Oracle Exadata Cloud at Customer is that it can be managed without needing only DBAs. We have many features, including the observability feature that helps check performance and generates numerous reports about performance. We have also implemented APIs, enabling us to create and perform many operations. This means we need DBAs who can work with APIs. We are autonomous in the patching process and don't need Oracle for patching. If you configure the process of patching, it will be executed automatically. We are using dynamic scaling which is implemented on an external virtual machine, helping us to downscale or upscale the CPU. Oracle Exadata Cloud at Customer has supported our organization's compliance and data sovereignty without problems. I have observed some limitations. For example, regarding encryption, though it is mandatory for Exadata Cloud at Customer, we cannot encrypt the database with external keys. Currently, with Exadata Cloud at Customer, using external keys is not possible.

Quotes from Members

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

Pros

"Microsoft Azure HorizonDB has positively impacted my organization by reducing latency issues, improving performance, and providing a good recovery time."
"I appreciate the features that Microsoft Azure HorizonDB provides, particularly the seamless transformation of the database, data collection, and database access along with the analytics features."
"Since we are in the proof of concept phase, we have noticed some early improvements and potential benefits that stand out so far in terms of speed, reliability, and ease of management."
"Using Microsoft Azure HorizonDB provides better scalability and performance in terms of database administration."
"We have migrated mission-critical databases to Exadata and gained significant performance in our OLTP and Batch jobs."
"The best feature of Oracle Exadata Cloud at Customer is that it can be managed without needing only DBAs, with observability features to check performance, generate reports, and implement APIs for creating and performing many operations."
"I am particularly fond of the intelligent capabilities that enhance the backend, utilizing technology to analyze SQL queries."
"I like that Oracle Exadata Cloud at Customer is a stable, well-positioned product in the market today, and it's very scalable."
"Performance has significantly improved."
"The operation model is the most valuable feature."
"Exporting and importing is easy because of its cleanliness, making the process easier. However, setting up the Data Guard was more difficult. Despite this, the client experienced lower downtime."
"The most valuable feature is that it is based on Exadata infrastructure, which is Oracle 's leading engineered system that is trusted, fault-tolerant, and has unique performance features."
 

Cons

"So far, I have not seen any return on investment from Microsoft Azure HorizonDB in terms of cost."
"I want to say that the costing of Microsoft Azure HorizonDB is too high and should be less."
"Regarding needed improvements, I feel that we need more documentation on Microsoft Azure HorizonDB."
"One area I can identify for improvement is query performance during peak traffic situations."
"A room for improvement in Oracle Exadata Cloud at Customer is that they need to train more partners to gain more knowledge because currently, they are keeping a lot to themselves. For example, they are still keeping a lot of information on their campus, so information sharing is limited."
"Today their support no longer lives up to my expectation."
"The solution is expensive."
"Oracle Exadata Cloud at Customer is stable, but the only problem occurs during OS patching. If you encounter issues, the VMC (virtual machine cluster) becomes unusable."
"As a customer, you can't see the boot messages of your virtualized guest machines."
"We had some problems in the developer's environment. We had some problems with the initial installation environment."
"For the data migration, we used ZDM. It was not integrated with the databases, and the documentation lacks clarity."
"Scalability is not straightforward."
