Customer Challenge
About 90 mixed Windows and Linux servers were housed in the VMware-based architecture of Destek Yatırım, which was spread across three data centers. The IT staff had several difficulties in monitoring, cost optimization, and performance tuning because of the size and diversity of the server fleet.
Numerous issues were brought about by this multi-data-centric architecture, such as poor visibility, wasteful resource use, intricate network configurations, and elevated operational load. Cost optimization, capacity planning, and high availability assurance were all manual procedures that took up significant engineering time. They ran the danger of more downtime, higher IT expenses, and less scalability for future company expansion if these problems were not resolved.
Partner Solution
By making only minor changes to the existing application structure, Onkatec offered a seamless migration to AWS with the AWS Application Migration Service. The entire VMware-based architecture was migrated to Amazon EC2, providing continuity and consistency while leveraging the benefits of a modern cloud-based infrastructure.
The client’s multi-site architecture was reflected in a scalable and secure Amazon VPC design with subnet segmentation and routing tailored to each workload. Elastic demand-based scaling was enabled by the deployment of Auto Scaling Groups (ASGs), which increased performance during peak hours and reduced unnecessary overhead during off-peak hours.
Amazon CloudWatch was integrated to provide real-time performance monitoring and alerting. EC2 Compute Optimizer was also used to continuously evaluate and optimize instance types and sizing based on actual usage metrics. Secure site-to-site VPN connections were established between AWS and the client’s on-premises data centers, ensuring a seamless hybrid architecture and uninterrupted operations throughout the migration process. Onkatec provided full lifecycle support, including pre-migration assessments, implementation, testing, and post-migration optimization. This approach minimized disruptions while ensuring operational continuity.
Results and Benefits
After the migration, Destek Yatırım significantly improved the scalability and manageability of its infrastructure. By enhancing CloudWatch and Compute Optimizer, they reduced overprovisioning and increased resource efficiency by up to 30%.
Centralized monitoring and automatic scaling significantly reduced operational overhead. Response times were reduced by approximately 40%, freeing the IT team to focus on strategic initiatives rather than maintenance tasks.
With secure and reliable connectivity and a more agile infrastructure, Destek Yatırım optimized its current operational costs while preparing for future growth. The new environment increased system resilience, simplified management, and delivered high performance for business-critical workloads.
