Datavail: Migrating SQL Server to AWS – FastPass
Migrating SQL Server to AWS – FastPass Are you planning to migrate your SQL Server environment to AWS but unsure where to start? This comprehensive presentation by JP Chen, Senior Director and Global Practice Leader of SQL Server Services at Datavail, provides a clear roadmap for a successful migration. What You’ll Learn: Why migrate SQL Server to AWS? Understand the business and technical benefits of moving to the cloud. Deployment options: Explore Amazon RDS for SQL Server and Amazon EC2, and choose the right fit for your workloads. Essential AWS services for SQL DBAs: Gain insights into tools and services that simplify management and improve performance. AWS Database Migration Service (DMS): Learn how to leverage DMS for seamless migrations. DBA responsibilities in the cloud: Discover how roles evolve in a cloud-first environment. Case Study Included: See how Datavail migrated a customer’s on-premises SQL Server environment to Amazon RDS for SQL Server, implementing Multi-AZ + Read Replica for high availability and disaster recovery. Learn how routing reporting workloads to a read replica improved performance and reduced operational overhead.

- 7. www.datavail.com 7 On-Premises Example: Useyour own server in your network with upfront costs; you are responsible for maintenance and uptime. Infrastructure as a Service (IaaS) Example: Use an Amazon EC2 instance (VM). Less upfront cost, as you are leasing it. You can customize the server to your exact requirements. You are still responsible for updates, security, uptime, and maintenance. Platform as a Service (PaaS) Example: Use Amazon RDS from AWS. Minimal upfront cost, and you do not need to be concerned about the maintenance of the machine.

- 12. www.datavail.com 12 Fastest wayto migrate is to backup and restore databases RDS supports native restores of databases up to 16 TB. If your database can go offline, then use native backup and restore to migrate it to Amazon RDS. Else, use AWS Database Migration Service (AWS DMS).
