A deployment plan should fit the application, its expected usage and the people who will maintain it. There is no single hosting setup that suits every project.
Hosting
Review the application’s needs, budget and support requirements before choosing managed hosting or a server. Make ownership of domains, accounts and credentials clear.
Release process
Plan how updates will be tested and released, how configuration will be managed and how a failed change can be rolled back. Keep the process documented for whoever supports the product.
Ongoing care
Agree on monitoring, backups, updates and response expectations. The right setup is one the team can operate consistently as requirements change.
