About the Client:

Client is a national leader in US health care solutions for people who are at a low-income level and/or are chronically ill. From their humble beginnings in 1983 in a West Philadelphia hospital, they have grown into one of the largest and most respected Medicaid managed care organizations in the country. Today, they serve approximately 5 million members in 13 states and the District of Columbia.

Background:

As client organization grew in size over the last decade, their legacy and on prem data infrastructure started to become a hindrance rather than an enabler for growth. During Covid Pandemic it became a glaring issue on how to manage and handle the on-prem data infrastructure as many resources starting to work from home and leaving the job market. This is when client took a decision to move its data infrastructure to Azure cloud (as client data environment is Microsoft Heavy). 

Cloud Migration To Azure For An Insurance Provider

 Challenges: 

  1. Lack of inhouse expertise in handling cloud migration.
  2. Lack of expertise in handling a complete SAP BO migration to cloud with all its current application connections

Approach: 

  • An audit of user environment was carried out to determine the usage of the platform by different departments
  • A detailed analysis was carried out to divide the data into different buckets
  • A prioritization study was done on which buckets should be shifted to cloud first
  • A logical framework was developed to carry out the load in sequential manner
  • A timeline was established to move 4 terabytes of Instances data to Azure cloud from SAP BO on prem system.
  • Study was carried out to identify dependencies of SAP BO in Azure
  • A road map was created with minimal user impact and minimum downtime
 

Solution:

Implementation of the solution in a two-pronged approach.

Building up the infrastructure in the cloud

  • We did server sizing and installation of SAP BO
  • Tuning the SAP BOBJ as per the grown user base and usage 
  • Setting up the monitoring of SAP BO
  • Integration with Azure Active Directory and SSO Setup
  • Setting up the DB drivers with new Azure DB servers
  • SMTP setup 
  • Search indexing and APS Sizing setup
  • NAS/SAN integration with SAP BO
  • Disaster Recovery (DR) setup of the BOBJ environment
  • Horizontal cluster nodes with Service load balancers and Web server load balancers

Migration of On-Prem SAP BO to Azure cloud

  • Security migration, folder level 
  • Content (Webi, Crystal, Dashboards, Inboxes, Files, Shortcuts, Favorites, migration, Instances, Publications etc)
  • Instances that were created from many years are migrated. 
  • Schedules and publication migration with minimal impact to the business.
  • Users’ personal folder migration 
  • Updating the connections to the new DB’s (PostgreSQL, Sybase, MS-SQL server)
  • DNS Mapping for correct mapping in the new Azure cloud

 Outcome:

  • The entire migration from SAP BO on-prem system to Azure cloud only took 6 months, this is including entire historical data migration
  • The efficiency of the new framework allowed for a quick migration of real data within 2 days (20-30 GB data) after the implementation of new Azure cloud system
