Cloud Exit Strategy
For secure data and minimized risk in the event of a strategic withdrawal from the cloud
What happens if your cloud provider suffers a partial data loss or fails completely and you can no longer use its services? A well-thought-out cloud exit strategy is essential to minimize such risks and maintain business operations. This strategy ensures that data and services remain recoverable even if the cloud provider fails and that the transition to a new provider or back to on-premises solutions runs as smoothly as possible. Below you can find out more about the technical measures that should be part of your exit strategy for the cloud in general and for Microsoft 365 in particular.
It’s Always Good to Have a Plan
A cloud exit strategy helps companies to react to unforeseen events. The measures required for this affect many areas of IT and the entire organization.
Risk assessment and planning
Carry out a risk analysis to identify potential failure risks of the cloud provider. These risks vary depending on the provider. From insolvencies and natural disasters to political instability, you should consider various aspects. After weighing up the risks, develop a business continuity plan (BCP) and a disaster recovery plan (DRP) to meet the requirements of a stable and secure infrastructure.
Process customizations
Document all business processes and their dependencies on cloud services to ensure a smooth migration. Train your employees regularly and ensure that the necessary know-how for the administration and migration of cloud services is available.
Technical Measures for a Cloud Exit Strategy
For an effective exit strategy from the cloud, you can take various technical measures. These ensure that data and services remain available even in the event of a planned or unplanned exit from the cloud. This includes regularly reviewing and updating security guidelines to prevent data loss or security gaps. You should also ensure that all applications and services that are operated in the cloud also function in a similar way in an on-premises environment or with another cloud provider. This increases flexibility, simplifies the exit and reduces dependency on a single provider.
Regular training and tests prepare your IT team for real emergencies. In the event of a data loss or system malfunction, employees know exactly how to respond quickly and effectively. By regularly testing backups, you ensure that the data is correctly and completely backed up and can be restored. Companies should also implement mechanisms to continuously monitor the cloud infrastructure in order to identify potential problems at an early stage and initiate countermeasures (e.g. ransomware).
Data Export and Transfer
Regular data exports: Ensure that data is exported regularly and saved in a standardized format. This makes it easier to migrate to a new provider or back to on-premises solutions.
Standardized formats: Use common data formats such as CSV, XML or JSON to ensure compatibility with different systems. Document the data export in terms of content and metadata.
Automated backups>: Implement automated backup processes to ensure that current data is backed up regularly. These backups should be stored in a secure, independent location.
Backup target: A backup target for a cloud exit strategy should always be outside the cloud to ensure the independence and security of the data. If the backup is stored within the same cloud, there is a risk that the primary and secured data will be affected in the event of a failure or security breach of the provider.
Test migrations: Carry out regular test migrations to ensure that the migration process runs smoothly and that all data is transferred correctly.
By implementing these technical measures as part of their cloud exit strategy, companies can ensure that they are prepared for various failure scenarios and can maintain business operations even if the cloud provider fails.

Special Features of Microsoft 365 SaaS Services
Developing a cloud exit strategy for SaaS services such as Microsoft 365 is particularly challenging as they are deeply integrated into business processes and are often based on proprietary technologies. SaaS providers offer customized solutions that are difficult to replicate when switching to another platform. In addition, data migration and security are critical aspects, as the data may be available in different formats and structures. The dependency on specific programming interfaces and integrations makes the switch even more difficult. Appropriate planning also helps to minimize risks in this case.
Use third-party backup solutions to increase data security.
Ensure that the use and storage of Microsoft 365 backup data comply with applicable regulations and that all data is encrypted during transfer and at rest.
Implement MFA and RBAC to make access to Microsoft 365 services more secure.
Develop a detailed migration strategy for the cloud exit and design a scenario that enables key business processes to be maintained even without Microsoft 365 services.
Problems When Exporting to Non-Microsoft Systems
Authorizations and structures: Problems can occur when exporting data from Microsoft 365 to non-Microsoft systems, as authorizations and data structures may not be compatible. It is important to take these differences into account and make appropriate adjustments.
Data formats: Make sure the exported data is in a format the target systems support. This may require additional conversions and adjustments
Conclusion: Your Cloud Exit Strategy for Sustainable Success
A carefully developed cloud exit strategy ensures that your IT infrastructure and business processes can cope with the demands of a provider change and that potential risks from a cloud outage are effectively minimized. Even if the permanent failure of one of the major hyperscalers is highly unlikely, you should conduct a comprehensive risk analysis and develop a business continuity plan and a disaster recovery plan.
It is important to document all business processes and their dependencies on cloud services and to train IT staff. Technical measures such as regular data exports, using multi- or hybrid cloud architectures, and implementing strict security guidelines are crucial. By combining these measures, you can ensure that you react flexibly and robustly to unforeseen events.
