Diving into database migration and replication
There is significant demand for moving and continuous integration of enterprise data as shifting workloads to the cloud becomes a core requirement for next-generation data initiatives and application modernization. Particularly for enterprise databases supporting mission-critical applications, avoiding downtime is a key requirement during migrations to minimize both risk and operational disruption.
Legacy on-premises business applications pose a challenge when migrating to the cloud. Migrating large mission-critical applications that have been running for years is a daunting task that can be broken down into two major areas: migrating the business application tier and migrating the underlying databases. Complicating this further, end users must have uninterrupted access, so mission-critical applications must be available with no downtime. There are numerous business application migration products and services that assist with migrating the business application tier, but migrating the underlying databases that serve the business application is often the most difficult part.
A database migration to the cloud can take a few different forms. In this talk we will cover architectural concepts on database migration and continuous replication. We will discuss a range of use cases from seemingly simple to more complex involving moving several databases in conjunction with an application modernization.
