HADR (High Availability and Disaster Recovery) Automation and Assurance for Microsoft SQL Sever Environments Becomes A Top Priority in 2014

A Contributed Article by Don Boxley, Co-Founder and CEO, DH2i

In today's highly dynamic data center environments, it is standard to have one or more non-clustered SQL Server instances that are each critical components of an overall service delivery requiring high availability (HA) and disaster recoverability (DR).  In such environments, budgetary constraints typically dictate the HADR must be delivered as one.  Likewise, recovery point and recovery time objectives (RPO and RTO) demand instantaneous fault detection and immediate failover, in order to meet service level agreement (SLA) requirements.  Further complicating matters, there are oftentimes dependent applications and/or services that also necessitate coordination in order to meet complete service delivery SLAs.  Unfortunately, conventional options for SQL Server HADR only address the SQL Server instance or database availability, with limited (non-existent) dependency coordination.  Until very recently, the industry has lacked a consistent method to address these requirements across multiple heterogeneous operating systems and SQL Server versions and/or editions.

In 2014, the industry will demand a comprehensive application virtualization solution that addresses these requirements.  Accordingly, the solutions that will rise to the top of essentially every enterprise short-list will include the following: 
  • Automation Engine - monitors, alerts and initiates SQL Server instance failover; for full service level delivery of dependent applications and/or services
  • Storage Replication Direction and Read/Write Coordination - provides extra measure of redundancy; immediate access to replicated data minimizes/eliminates downtime; streamlines and ensures DR
  • SQL Server Instance Virtualization Engine - adds flexibility, speeds and ensures complete transparency in delivery of new services, and enhances availability and DR capabilities
  • Intuitive Administration Console - for fast/easy provisioning, patching and updating of all SQL Server instances
  • Advanced Multi-Subnet Clustering - for always-on high availability
  • SLA Framework - ensures RTO and RPO requirements are met
  • Simultaneous Support for Heterogeneous Operating Systems and SQL Server Version(s) and/or Editions - for flexibility and extreme cost savings

This year, next year, any year...  a top priority for any IT manager or database administrator is to guarantee that their databases and applications never go down - and if one does, they can get it back up instantly and completely transparently, with zero data loss. 

For IT managers and database administrators that are responsible for managing multiple SQL instances, it's really quite simple.  In addition to enabling highly efficient and cost effective management of SQL Server instances across physical, virtual and cloud environments, 2014 will mark a year during which these shrewd IT professionals require a solution that ensures the highest levels of availability and complete disaster recoverability (HADR).  In 2014, uninterrupted access to business critical applications, information and services will be the name of the game.
