Yulianto Artawan - PeerSpot reviewer
Field Services Engineer at Tetrapak
Trend analysis has improved troubleshooting and program testing for accurate, reliable outputs
The features I appreciate most in GE Proficy Smart Factory MES are the ability to create trends when I troubleshoot during my daily work. I can also edit the program in GE Proficy Smart Factory MES, and before I download it to the PLC, I can test it first to ensure my program is working correctly. GE Proficy Smart Factory MES has been very useful in my daily work because it is user-friendly. I can also go online and change the IP address easily, which is simpler compared to other solutions. Troubleshooting with GE Proficy Smart Factory MES is easier than other options.

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.
