Today’s Imperative: Become a Digital Enterprise (Gartner)

You have these capabilities throughout your data center:

The Digital Enterprise • Availability – continuous despite system failures

• Scalability – 1000s of distributed resources

• Agility – flexible infrastructure, incremental capacity

“IT is the business”

But your database has not kept up


Forced 1:1 Tie Impedes Continuous Availability

• Failover and maintenance disrupt apps

• Scaling (up or out) for performance takes code changes

• Lack of visibility hampers troubleshooting

• Lack of centralized control and auditing complicate security

Break the 1:1 Tie with Database Load Balancing Software

• Transparent deployment; app agnostic

• Fastest, most cost-effective path to continuous availability and scale

• Achieves business mandates for both on-premise and cloud

• Centralized visibility and control

State of Application Uptime Survey – Key Findings

1 Database failover takesdown applications.

Database outages are too frequent and too long.

Database maintenance crushes resources.

Deferred “security patching” is rampant, placing enterprises at risk.

Compensating for AlwaysOn’s Weaknesses

on Microsoft:

CHALLENGERS LEADERS

VISIONARIESNICHE PLAYERS

Magic Quadrant for Operational Database Management Systems16 October 2014“Cautions:”

• Market image: “perception of weakness” as “an enterprise-class DBMS.” “…continuing perception that SQL Server is not used for mission-critical apps…”

• HA/DR issues: “Microsoft received one of the lowest overall scores for ease of implementing HA/DR.”


Gartner Validation: Cool Vendor Award!

Why cool

• Database failover transparent to the application

• Linear scaling for elasticity with no downtime

• Automatic read/write split to leverage database replication and scale out with no application changes

• Zero-downtime maintenance – increasingly important as patch frequency increases

• Optimizes capacity utilization and queues loads during failover to prevent application errors

Who should care

• Information managers

• Data center operations specialists


Case Study: MicrosoftContent

Challenges• Migrate from SQL Server 2008 to 2014• Overcome limitations of AlwaysOn

• Not replication aware • No geo-aware load balancing• No method for detecting failover state

of Availability Groups• Avoid app rewrites to support 2014• Streamline maintenance, patching, testing

ScaleArc Solution• Accelerated project timeline from 9 months

to 4 months• Provides auto failover across data centers,

avoiding app errors during failover• Supports automatic read/write split• Provides geo-aware load balancing• Enables zero-downtime maintenance• Supports 8x traffic capacity• Utilizes all deployed SQL Servers
