Know what the platform already manages
A hosted commerce platform and a custom application have different responsibilities. Identify which layers your provider operates and which remain yours: integrations, custom storefronts, databases, domain configuration and access control. Avoid paying to solve a hosting problem that the chosen platform already handles.
Define failure and recovery
Agree what downtime means for the business and which functions must recover first. Discuss backup frequency, retention and realistic recovery objectives. Restore testing matters more than a checkbox labelled backup; document the steps and the people who can execute them.
Watch dependencies and costs
Inventory external APIs, scheduled jobs, queues and credentials. Add monitoring for failures that affect customer journeys, not just server uptime. Establish budget alerts and ownership of cloud billing so an integration error or unexpected traffic does not create an unnoticed cost problem.
Plan migration deliberately
Create a dependency map, test environment, data transfer plan and rollback criteria. Check DNS, certificates, scheduled tasks, webhooks and redirects. Choose a launch window with the business and confirm who can make a rollback decision if something important fails.
Make infrastructure changes reviewable
Infrastructure as code records infrastructure requirements in configuration files that can be reviewed and versioned. Terraform can manage cloud resources, while Ansible can help automate configuration work. For an existing store, first inventory what already runs, decide who owns state and access, and test the proposed change in a suitable environment. Importing or changing production resources needs a reviewed plan and an agreed recovery approach.
Keep operations understandable
Prefer an architecture the team can support over one selected only for technical novelty. Document access, deployment, incident handling and routine maintenance. Revisit the design when real demand or reliability requirements change rather than forecasting every possible future scale at launch.
