Overview of this book

Cloud technologies have now reached a level where even the most critical business systems can run on them. For most organizations SAP is the key business system. If SAP is unavailable for any reason then potentially your business stops. Because of this, it is understandable that you will be concerned whether such a critical system can run in the public cloud. However, the days when you truly ran your IT system on-premises have long since gone. Most organizations have been getting rid of their own data centers and increasingly moving to co-location facilities. In this context the public cloud is nothing more than an additional virtual data center connected to your existing network. There are typically two main reasons why you may consider migrating SAP to Azure: You need to replace the infrastructure that is currently running SAP, or you want to migrate SAP to a new database. Depending on your goal SAP offers different migration paths. You can decide either to migrate the current workload to Azure as-is, or to combine it with changing the database and execute both activities as a single step. SAP on Azure Implementation Guide covers the main migration options to lead you through migrating your SAP data to Azure simply and successfully.

In most cases the business will also need to be heavily involved in planning and executing the test plans used to validate the migration.

We cannot provide a definitive answer as to which migration option will be right for you, but we hope that this chapter gives you an idea of the options you have and the advantages of each of them. In many cases you will use more than one migration option, possibly using lift-and-shift for some SAP applications, and lift-and-migrate for others; for example, migrating from BW on AnyDB to BW on HANA. For many of the smaller systems, the downtime required will be fairly short and you may take a very simple...
