Cloud readiness assessment for existing applications | Anexia

In the cloud migration analysis, we check which parts of an application depend on their current location and operating model. These include local file access, fixed network addresses, identity services, database characteristics and manual operating procedures. A possible move is assessed on the basis of these concrete prerequisites. The technical ability to start in a cloud environment is not a sufficient basis for a decision.

For the cloud assessment, we also examine the load profile, data transfer and recovery requirements. Certain dependencies can significantly change costs or latency after a move. In the Cloud Readiness Assessment, suitable options are distinguished: unchanged relocation, targeted adaptation, larger modernisation or remaining in place for the time being. Each option is given technical prerequisites and recognisable follow-up tasks. A limited proof can clarify particularly uncertain points in practice. The outcome of cloud readiness work is a well-founded decision paper for each agreed part of the application. It shows which preparation is necessary and which assumptions still need to be confirmed before a migration is approved.

Scope of services for the Cloud Readiness Assessment

The agreed scope for the cloud migration analysis can include the following results: application inventory, dependency analysis, target options, effort range and prioritised migration waves. For each key result, we define what it is for, who reviews it and in what form it is handed over. This allows development, operations and procurement to assess the same service. Vague umbrella terms are replaced in the proposal by concrete work packages.

The cloud assessment also includes coordinating the necessary interfaces with your team. We clarify access, contacts and available testing options before the relevant implementation steps. Changes to the scope are described together with their impact on effort and sequence. This gives you a clear overview of delivered results, outstanding prerequisites and additional requests.

The key technical decision in the Cloud Readiness Assessment

Unchanged relocation, targeted adaptation and larger modernisation are compared on the basis of the same use case. For cloud readiness, we document the relevant assumptions and explain the reasoning behind the chosen option. Key alternatives are assessed against the same business requirements. This makes later adjustments easier when load, data volumes or organisational responsibilities change.

A sound decision also takes maintainability and handover into account. For the cloud migration analysis, we assess which skills are available internally and what additional support is needed. This links technical possibilities to a realistic operating model. The client can see which tasks will recur after the project and which decisions remain with them.

A low-cost start can become more expensive than expected due to data transfer, operating effort or necessary adjustments after the migration. We treat this point as a concrete test question in the cloud assessment. Each risk is linked to the affected process, its potential impact and a suitable measure. Where prerequisites are still missing, the statement explicitly remains open until the necessary investigation has been carried out.

We check load profiles, network dependencies, data backup, restart and the actual requirements of target operations. For the Cloud Readiness Assessment, we record the starting point, the tested configuration and the result. Acceptance relates to the agreed scope. Open limitations are documented visibly and assigned to an owned next step. This allows your team to distinguish between proven functionality, a deliberate decision and an assumption that has not yet been confirmed.

Project example as an illustrative scenario

The following scenario is an illustrative example and not a customer reference. A company wants to move an existing application out of a data centre model that is being phased out. In the Cloud Readiness Assessment, the scope of the investigation would go beyond the visible servers. Scheduled tasks, file shares, local identities and external connections could be just as important for operations as the actual web application.

For cloud readiness, dependencies and critical business processes would be recorded. Unchanged relocation, targeted adaptation and a larger rebuild would be compared on the basis of the same requirements. A technical trial could show whether increased latency to a remaining business system is acceptable. Data transfer, licence terms and recovery would be included in the assessment. Missing information would have to be identified as concrete preparatory work. A theoretically supported operating system would not be sufficient proof that the entire application runs economically and reliably in the target model.

The result of the cloud migration analysis would be a well-founded migration path with recognisable prerequisites. It would include an inventory overview, prioritised risks and suitable transition stages. The recommendation could leave individual components at their current location for the time being or provide for preparatory decoupling. The client would need to understand which steps are required before binding relocation planning and which assumptions still need to be tested in practice. The actual migration would remain a separately planned implementation step requiring its own approval.

Our experience and our engineering approach

We combine custom software development with the technical tasks of introduction and further development. For cloud readiness, we bring the perspectives of application, integration and operations together in one shared workflow. Business requirements remain linked to the technical decisions. You work with a defined scope of services and traceable results.

Our experience should be concretely verifiable for your project. That is why we explain in a technical discussion how we investigate the relevant risks, which work results are planned and how your team can assess them. For the cloud migration analysis, we align the roles involved with your actual needs. Available references are presented with their respective project and company context; confidential client details are not used as general marketing claims.

Effort for the cloud migration analysis

The quality of inventory data, the number of applications and the technical trials required influence the analysis effort. We therefore estimate the Cloud Readiness Assessment on the basis of a defined scope and explicitly stated prerequisites. An initial analysis step can be useful if essential technical information is still missing. Work packages and acceptance criteria can then be agreed more reliably.

Cloud readiness work can be organised as a limited project, as a joint implementation with your team or with subsequent support. Usage rights, access, documentation and responsibilities are clarified in the contract. Ongoing operating hours, response times and external consumption costs are covered by separate agreements. This keeps it clear which services are delivered once and which tasks recur after introduction.

Boundaries of the Cloud Readiness Assessment

The assessment is separate from the actual migration but provides concrete prerequisites and acceptance criteria for it. For the cloud assessment, we record this boundary in the proposal itself. Any additional services required are included with their business justification and are not tacitly assumed. This allows your team to plan suitable internal skills and divide the overall work sensibly among those involved.
