Microsoft Premiere Support helped Infosys design
a solution based on SQL Server 2012, Always-On
High Availability (a feature in SQL Server), and
an 8-node Windows Cluster with Failover Cluster
Instances for 11 SQL Server cluster instances.
The team blocked off a year to create an upgrade
and migration plan that would reduce down time.
This included:
01. Completing a feasibility study, as well
as proof-of-concept and network
bandwidth testing
02. Generating reports to highlight and address
upgrade obstacles
03. Assessing the risk of online transaction
processing environment and the upgrade
complexities for new features and add-ons
in SQL Server 2012
04. Creating performance baselines and
comparing and analyzing pre- and post-
upgrade query performance
05. Scripting, testing, and automating a majority
of the upgrade tasks
06. Creating a step-by-step and overall review of
the upgrade plan
Infosys and Microsoft Premiere Support completed
the upgrade and data migration over a few
days. Once complete, Infosys saw immediate
performance improvements:
• Reporting latency dropped from two hours
to near real-time
• Speed of frequently run data queries
improved by 70 percent
• Execution of BI reports reached near real-time
Other benefits included broader integration
with third-party applications and access to new
BI tools such as Tabular Models in SQL Server
Analysis Services. And with the added ability to
scale SQL Server workloads on demand from its
datacenter to the cloud, Infosys can now build
hybrid BI and OLTP apps that are more powerful
and will help the company perform at its peak.
