Business Critical Applications (SQL) are Moving to Cloud - Last No tolerance for downtime Recovery Time and Point Objectives High Availability and Disaster Recovery Protection Application response time is critical Performance More need for flexibility and agility Resource allocation, efficiency, reliability Copyright © 2017 SIOS Technology Corp.

What are the minimum requirements for moving to the Cloud? Want to gain Dynamic resource allocation Configuration flexibility Cost efficient DR Rapid provisioning Business agility Don’t want to give up Control Flexibility Performance High Availability Disaster Recovery But Copyright © 2017 SIOS Technology Corp.

Redundancy is not enough. Microsoft SQL Server cannot be made redundant with a simple load balancer and multiple instances in different “Availability Zones” Web and application services in different geographic locations in the cloud What about the Data Tier? Databases such as SQL Server need additional configuration Availability Zone Availability Zone Load balancers in front of Web or Application servers Copyright © 2017 SIOS Technology Corp.

Moving SQL Server to the Amazon Web Services Cloud Cloud does not negate the need for HA, DR and Backup Options are basically the same as on premises, but no SAN available Availability Groups Quick Failover Readable Secondary Automatic Page Repair Does not require 3rd party products Failover Cluster Instance Protects Entire Instance Supports DTC Works with SQL Server Standard Edition Supports SQL Server 2008 R2 and earlier Easier Management Copyright © 2017 SIOS Technology Corp.

High Availability Clusters in Cloud Environments Failover SQL Server Storage High availability failover clustering with WSFC requires shared storage that is not available in cloud Copyright © 2017 SIOS Technology Corp. All rights reserved.

High Availability Clusters in Cloud Environments SANless Clusters synchronize storage in cloud WSFC sees synchronized cloud storage as a SAN You get added configuration flexibility and ease of use Failover SQL Server Storage Replication Copyright © 2017 SIOS Technology Corp. All rights reserved.
