Adoption using Cloud EDMA
Customer
The US Indices arm of one of the largest exchanges in Europe
Business Scenario
The organization was increasingly becoming data-driven, this
led to their Line of Businesses (LOBs) to spend considerable
amount of time and resources on data collation and analysis
to create meaningful insights. The other challenge faced by
these LOBs was the enormous time taken by the centralized
IT department to provision Data for them.
Based on our discussions with the client, the following
challenges were identified
• SQL Server based DW application that was developed
over past 12 years required enormous efforts to add new
data elements
• DW application was not scalable and had performance
issues
• The availability of the system was limited to few key
stakeholders based in US
Solution Delivered
Hexaware’s leveraged its Cloud EDMA (Enterprise Data Management
and Analytics) platform to assess the current situation and devise ways
to overcome these challenges. Hexaware came up with a cloud
readiness score and the probable RoI the customer will get post cloud
transformation and came up with the option to build a highly scalable
cloud data warehouse on AWS that could be provisioned in a quicker
time frame and handle high volumes of data processing. A 2-year
roadmap was defined to completely build the DW and Analytics
infrastructure on cloud. Using Cloud EDMA’s cloud consulting services,
various tools on AWS were evaluated and finally a stack based on
EMR, Red Shift, Talend and S3 was recommended to the client. The
processed data was transformed and stored in S3, and Amazon’s
columnar DB- RedShift, EMR was used for Data processing
on-demand. Hexaware assessed the existing DW based on SSIS jobs,
Stored Procs, SSRS reports, fund fact sheets leveraging the IP tools
and defined the incremental scope of work as phase 0, 1 and 2 as a
one-year program. Phase 0 was the foundation solution to
demonstrate the capability of the platform, Phase 1 of the project
comprised of gathering data from 3 primary data sources followed by
8+ data sources in Phase 2.

Business outcome
• Cloud EDMA solution eventually lead to savings of about £800,000 of Operational Expenditure a year in infrastructure and licensing costs
• Moving completely to cloud reduced several hours of multi-part data ingestion to automated single bulk load thus saving about 6 hours
on data loading time
• EMR, the managed service component of AWS serving the role of an Administrator performed auto-scalability of instances based on the
processing need.
• The Cloud Data Warehouse which was mainly built for internal stakeholders was extended to deliver information and analytical insights
for external clients through a self-service model.
