The same data set is shared across the entire system. Particular concerns to not duplicating data and using a single source of truth whenever possible. API REST, Micro-services architecture, Messaging oriented middle-wares may helps to reach those goals.

High quality deployment: high availability, load balancing and automatic scaling become accessible even for a middle and small businesses. Cloud may be private or, more efficient, hybrid when linked to on-premise system. Thanks to massive virtualization of cloud infrastructure, deployment and configuration can be highly automated. Tools like Terraform or Ansible may helps to reach those goals.

Systems hardening, zero trust data security and robust identities management with a good IAM may helps to reach an efficient security level.

First deployments and maintenance in operation condition (MOC) of all system modules must be done using DevOps process flow. This ensures rigorous application of procedures for greater efficiency and safety while saving time. Tools like Git, Jenkins, Docker permitting CI-CD pipelines with automated tests may helps to reach those goals.
