Kardem – Success Story

Sustained by our global network of partners and suppliers, Kardem specializes in design and high-tech production of high-volume, time-sensitive fashion garments and collections for Turkey and the world’s leading brands. Using a lean management approach, we reach an average total production capacity of 2,000,000 units per month and the number of employees is 900.

Need

Kardem's SAP and Non-SAP server systems were randomly scattered throughout different data centers. For servers hosting important applications such as SAP, robotic systems, and smart device management, this mixed structure caused problems such as accessibility, manageability, continuity, cost and inability to implement standards. A more effective and integrated solution was needed to minimize all these problems, by consolidating other management requirements as well.

Solution

For Kardem, operating various locations in Turkey and abroad, a Hub and Spoke structure, which was also one of the most important components of the Landing Zone design, was created in a configuration to ensure providing safe and regular access from each point.

Azure architecture, which is fully compatible with Microsoft's Cloud Adaption Framework (CAF) and Governance standards, was created by also taking into consideration the company policies and standards.

With Azure's Native Assessment and Migration tools, server analysis and dependencies as Agentless for servers on Hyper-V and Vmware Hypervisor platform are extracted, and all critical systems from SAP systems, especially SQL, CRM and 3rd party applications are within the plans created. Seamlessly transferred to the Azure environment using the Rehost method.

Using Azure's Native Assessment and Migration tools, Agentless server analysis was carried out and dependencies were identified as for servers located on the Hyper-V and Vmware Hypervisor platforms; all critical systems, especially the SAP systems, were migrated to the Azure environment seamlessly according to the plans developed.

After completion of the developments and QA, system integration tests were carried out by running the scenarios determined before the migration. The same tests were also carried out after go-live.

Benefit and Result

  • 31 servers were migrated to the Azure environment, minimizing the possible risks and service interruptions before the Azure migration through accurate analysis, evaluation, and dependency identifications completed for SAP and Non-SAP server systems on two different virtualization platforms with the features provided by Azure Migrate.
  • Systems migrated on Azure have been transformed into more secure, accessible, and manageable systems to ensure continuity and flexibility.
  • A more manageable and cost-saving environment was created by deploying a flexible and scalable structure.
  • Hardware needs of servers, which are required for performance reasons, were met with Azure without any investment.
  • Key mechanisms such as monitoring, security, and access control were implemented for infrastructure and workloads.
  • Servers hosting SQL workloads were switched to SQL on IAAS VM structure and optimization was achieved in SQL server maintenance, management and license items.
  • Standardization was achieved in management, cost, performance, and control levels by employing the principles and labels.
  • For each SQL Database hosted on IAAS VMs, Azure Backup provided backup and database level data redundancy.
