There are many issues when migrating or building a SaaS CRM and SFA in AWS.
- Data source integration (mainframe etc)
- SFTP and use of NLB
- Proper VPC networking and subnet configurations
- Use of NATs
- Data quality and ETL
- Back end storage and scalability
- File, Block, Object storage, backup, recovery, disaster recovery with IaC
- IaC or use of Terraform and CFT
- Monitoring, Logging, alerting
- ELBs, ALBs and scalability
- Management of the IaaS or configuration of the PaaS
- Security updates, upgrades
- OS choice and management
- CI-CD pipelines, integrated testing (code, security)
- Front end integration with the backend
- UI, UX and ease of use
- Mapping the UX to the backend schema
- Encryption everywhere
- Actual migration if that is what the use case is: DMS, SMS, AWS MGN and other tools
