Migration

AWS offers migration services that reduce the complexity and time for companies to migrate to the cloud:

• AWS Migration Hub: AWS Migration Hub allows us to monitor the progress of an application's migration within AWS resources and other partnering software tools. This makes it easier for us to get a high level of understanding about the migration's progress.
• Application Discovery Service: AWS Application Discovery Service is an intelligent service that collects and summarizes the usage of applications and their dependent services running on on-premise servers. This service can be where a user wants to migrate a system and wants to collect information about the on-premise server and find out about the dependent applications. It stores the collected data in the Application Discovery Service database, which will be in an encrypted format. Users can then export the data in CSV or XML format.
• Database Migration Service (DMS): AWS DMS is a service that helps to migrate databases from an on-premise server to the Amazon Web Services cloud. It provides support for same-origin vendor database migration, such as Oracle to Oracle, and cross-origin vendor database migration, such as Oracle to MySQL.
• Server Migration Service (SMS): AWS SMS is an automated service that migrates your on-premise server workload to AWS. This service can be scheduled and can take incremental migration as well.
• Snowball: Snowball is a petabyte-scale data transfer service whereby a user can migrate a large number of datasets from one system to AWS or vice versa. Transferring large amounts of data will incur a heavy cost for data transition over the network and may cause security concerns. So to overcome this, Snowball provides an appliance where we can attach an appliance to our local network and transfer the data.
