Cloud Migration in Action: DTEK’s Experience

Understanding the risks posed by the onset of war in Ukraine, DTEK Group initiated a large-scale project to migrate critical business services supported by MODUS X from on-premises data centers to cloud providers.

We developed a comprehensive solution, encompassing the migration of IT and business systems to Azure and AWS cloud providers, ensuring a secure and efficient transition:

• Migrated 32 IT and 36 business systems and services to Azure and AWS.
• Created landing zones in both providers for a seamless transition.
• Utilized AVS (VMware on Azure) and AWS VMC (VMware on AWS) solutions for technological compatibility and rapid migration of services.
• Implemented hot and cold virtual machine backup mechanisms using VMware HCX.
• Deployed Backup and Restore infrastructure based on Veritas NetBackup for restoring infrastructure from backups.
• Introduced Checkpoint solutions to ensure cybersecurity and traffic management in AWS and Azure cloud infrastructures.
• Built additional communication channels from offices using VMware SD-WAN appliances, connecting all data centers, offices, and production facilities of DTEK businesses.
• Deployed core infrastructure services: AD, DNS, NTP, PKI, ADConnect.

Results

• Deployed base infrastructure in two providers within one week.
• Achieved migration without business process interruptions or data loss.
• Ensured high levels of security, redundancy, and data availability. Cloud services provided protection against ransomware and unauthorized data modifications.
• Enabled quick scalability and flexibility in transitioning away from on-premises IT infrastructure.
• Implemented a Cloud Vendor No Lock strategy, ensuring independence from specific cloud providers.
• Met all information security requirements.
• Offered businesses a Pay-As-You-Go model for temporary workloads and development environments, reducing computing resource costs for 1-, 3-year, or longer-term usage with significant discounts (20-50%).
• Ensured backup data storage in geographically separated locations (600+ km from primary productive service regions) to minimize data loss due to catastrophic events.

MODUS X’s cloud migration expertise showcases how businesses can leverage advanced technologies to enhance resilience, optimize costs, and achieve operational continuity even in the most challenging circumstances.
