doing a full migration. You might also keep some of the data (or a copy of the data) permanently on-premises. Major Migration Tasks We suggest the following steps for a successful migration. Create a cloud migration plan The cloud migration plan should list all the databases and appli‐ cations in the order in which you want to move them to the cloud. The final assessment plan should delineate the migration plan for all databases. If you need new resources—in software, finance, or personnel—in the new database environment, that should also be in the plan. Determine who performs the migration DBAs and developers should work together on the migration effort because each team has something to offer. While choosing staff, you can also decide whether to employ a migration service provided by the cloud vendor or a third-party company. Educational tasks These include broad brush tasks such as understanding the use of the cloud vendor's tools, the specific features of the target database engine, the scope of the database migration, and the architecture of the cloud databases. Create the cloud database architecture Select the type of databases that you want to use, as well as whether to use a managed or self-managed database. When making this choice, weigh all relevant factors such as cost, per‐ formance, reliability, and scalability. Choose a migration process "Migrating the Database" on page 32 lays out the criteria for choosing among replication, backup/restore, or a dedicated migration service. For a self-managed database, create your computing infrastructure If you choose to manage your own databases in the cloud, create virtual instances and deploy them through the vendor's com‐ pute service, such as Amazon Elastic Compute Cloud (Amazon EC2). 28 | Chapter 3: Moving Your Databases to the Cloud
