Senior Database Administrator at a healthcare company with 10,001+ employees

Cloud migrations have become faster and active-active databases achieve near-zero downtime

FlashGrid Cluster for Oracle RAC is very secure regarding its AI capabilities. Most products today rely on cloud migration or are connected to AI, so I believe it is quite safe. Of course, there is room for improvement. The accuracy and reliability of FlashGrid Cluster for Oracle RAC has been excellent. In my experience, the accuracy and reliability have been all positive, and I have no negative things to say about it. It is very helpful and secure. FlashGrid Cluster for Oracle RAC is deployed in my organization in a hybrid and private cloud environment. I use Azure and AWS as my cloud providers. My advice to others looking to use FlashGrid Cluster for Oracle RAC is that I believe a trial period for every database administrator would be valuable. Everyone might love the solution if given the opportunity to try it. I rate FlashGrid Cluster for Oracle RAC eight out of ten because while there is room for improvement, it was easy to navigate and accomplish automated infrastructure deployment, which was very helpful.

Centralized networking has secured multi-cloud data pipelines and improves analytics reliability

VNS3 could improve in terms of ease of setup, as while it is powerful, initial configuration for complex multi-cloud topologies can still feel quite technical and requires strong networking knowledge. Another potential improvement would be to tighten native integration with modern data stack tools; Airflow, dbt, and cloud data warehouses can benefit from more out-of-the-box connectivity templates. Additionally, the user interface and observability experience could be more modern and intuitive, especially for quickly diagnosing network flows without diving deep into logs. A pain point regarding needed improvements is that troubleshooting can still feel quite network engineering heavy. For data teams in my organization, we often want more pipeline-level visibility, such as directly seeing which ETL jobs or data flows are impacted when a tunnel or route changes. I would also appreciate more automation around policy setup, such as having auto-generated secure network templates for common data architectures such as AWS to Snowflake or on-premises to BigQuery, which would significantly reduce setup time.
