ArcGIS Enterprise AWS Migration

Migrating ArcGIS Enterprise to AWS follows a structured approach to ensure a seamless transition while enhancing scalability, security, and performance. The process begins with an Assessment & Planning phase, which includes an evaluation of the organizations existing ArcGIS infrastructure, database dependencies, and storage needs. A target architecture is then designed using AWS services such as EC2 for ArcGIS Advanced Server, Amazon RDS for PostgreSQL, and AWS EFS for shared storage. AWS Landing Zone is configured to establish governance, security, and network connectivity.

A validation phase follows, testing database migration feasibility with AWS DMS and validating ArcGIS functionality on AWS infrastructure. Once confirmed, the Migration Execution phase deploys ArcGIS Advanced Server on AWS EC2, migrates SQL Server data to RDS PostgreSQL, and synchronizes GIS applications using AWS DMS or manual imports. This approach ensures minimal downtime, optimized performance, and long-term cost efficiency, enabling organizations to modernize their GIS infrastructure with AWS-native solutions.
