Multiple clouds. One clear plan.

A system cannot be placed sensibly without knowing its data paths. A locally operated application can be closely connected to a database, machine connectivity or user management. If individual parts are relocated, response times and dependence on connections can become more important. Together, we therefore examine which components should stay together and which can actually be operated separately. The desired use of multiple providers is assessed against these requirements, rather than being assumed as a goal in itself.

The target state takes the business benefit into account as much as the additional effort. Different environments may require their own access procedures, tools and skills. Ongoing data traffic and the support of shared interfaces are also part of the assessment. The decision documents why an application remains in a particular location or is to be relocated there. This results in an architecture that remains verifiable when changes are made later and whose distribution can be explained by the requirements of your applications.

A successful network connection does not by itself prove that the application works fully over that connection. Name resolution, user rights, data access and external interfaces can have additional prerequisites. During implementation, the required communication paths are therefore recorded and set up together. Technical and business stakeholders then review the relevant processes. This makes it possible to determine whether the environment is not just reachable, but actually fulfills its intended tasks under the new conditions.

Beyond that, we assess what happens in the event of an interruption. Which components remain usable, which processes have to wait and which data must be reconciled later? The answers determine which procedures are needed in operation. Tests and documentation make the limits of the chosen architecture visible. Where a desired behavior is not achieved, a deliberate decision must be made about adjustment, additional measures or the remaining limitation. This decision is part of the acceptance of the integration.

In the event of a disruption across multiple environments, it is often initially unclear which part is the cause. Without coordinated reporting channels, several parties can then each point to a different area of responsibility. Together, we therefore define who takes ownership of an incident, what information is needed and how further parties are involved. Coordination for changes is described as well, so that an intervention in one environment does not have unnoticed effects on other applications or locations.

A later switch is assessed on the basis of concrete dependencies: data export, services used, configuration and necessary adjustments to the application. Using multiple providers does not automatically mean that an application can be moved between them without further effort. These limits are documented and the potential effort is gauged. This gives your team a sound basis for future decisions and lets it assess what preparation would be required for relocating or consolidating the landscape.
