Migration to cloud has cut database costs and simplified shared storage but still needs lower latency

The best features FlashGrid Cluster for Oracle RAC offers include shared storage, which is critical because for on-premise Oracle high availability clusters, I do not need FlashGrid. When I migrate to the public cloud, I need FlashGrid to provide that shared storage. It is easy to migrate from on-premise to cloud because the Oracle architecture does not change; the only difference is that in the public cloud, shared storage block was not available, but FlashGrid provides that feature to the Oracle RAC cluster. FlashGrid Cluster for Oracle RAC has positively impacted my organization cost-wise because by migrating to the cloud from my on-premise data center, I could consolidate the price structure for my storage and compute needs. Oracle RAC was the bottleneck for that because previously, without FlashGrid, I could not configure Oracle RAC in the public cloud, but with FlashGrid, I managed to consolidate costs for Oracle RAC infrastructure in the cloud. After migrating with FlashGrid, I have a substantial presence of Oracle RAC clusters in my data centers, around 50 RAC clusters across the U.S., and each was costing around $100,000 per year per cluster. However, I was able to migrate 25 of those clusters to the public cloud using FlashGrid, and the cost was reduced to $50,000 for those clusters, meaning I saved $50,000 per annum for the 25 instances. After installing and configuring FlashGrid in AWS cloud, I was able to reduce the storage cost substantially compared to my on-premise data center storage. I saved $50,000 per Oracle RAC cluster per annum using FlashGrid, which includes both storage cost, compute cost, and also manpower cost.

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.
