Quelles sont les options de migration vers Azure pour une entreprise utilisant des infrastructures sur site ?

Hi @NDEMEZOGH'ESSONE Patrice René
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here. 

 Sometimes unexpected costs can catch you off guard during the migration process. To work around this, start by using Azure’s cost calculator to estimate your costs before you start. Set up real-time alerts to monitor your spending and take advantage of Azure’s cost advice, such as reducing or eliminating unused resources. 

 You may have a downtime change to Azure. To minimize this, plan your travel when your business is busiest. Use tools like Azure Site Recovery to help reduce downtime and thoroughly test your systems to make sure everything is working properly before turning it on completely. 

Data Migration Issues can be complicated, especially with concerns about data loss or corruption. Use Azure Data Box and Data Factory for efficient big data migration. Once you have moved your data, make sure it is accurate and complete, and always backup your data before you start the migration. 

Integration issues may arise because your new Azure system may not work properly with your existing systems. Before going live, be sure to test how your new system integrates with your current equipment. Azure Logic Apps and API Management can simplify system integration, confirming that all components are compatible with your existing system. 

If your team lacks Azure skills, consider investing in training to get them up to speed. You can also bring in Azure consultants to gain additional knowledge and take advantage of Microsoft’s extensive resources and support.
