Project goals:

• Setup ETL process based on Azure Data Factory, to move data between OLTP.
• MS SQL Server DB (on-premises environment) and Data Mart based on Azure Database for MySQL.
• Implement several aggregations and transformations into ETL

Accomplishments:

• The ADF pipeline has been designed to move extract data from SQL Server, perform all required transformations and load the data into the Data Mart.
• The service has been integrated with an on-premises monitoring system (Zabbix), to ensure robust, production-ready management and monitoring capabilities.
• Azure AD roles and users have been set up to fit the enterprise security/access policies.

Project goals:

• The client’s on-premises hardware was running out of support lifetime.
• It was required to find a cost-effective way to move from the mentioned hardware
• The system consisted of:
  1) a hardware hypervisor with 18 VMs running on top of it;
  2) a storage appliance;
  3) an Email server;
  4) a hardware firewall

Accomplishments:

• A detailed analysis has been conducted, to compare the pros/cons of 3 different ways to address the risks:1) Migrate the system to a brand-new hardware
  2) Migrate the whole system to Azure cloud services
  3) Set up a backup solution in the cloud, to ensure a seamless switch-over to the cloud in case of the on-prem system’s failure.
• A decision has been made to proceed with the 3 rd option implementation
• The backup system has been built in Azure Cloud, utilizing cloud-native services where possible to optimize costs and simplify maintenance (Storage, DB, Mail server, monitoring solution)
• Such an approach allowed us to minimize the cloud deployment costs to 20% if compared to classical cloud migration.
