Clariant's Transition to Internet-Based WAN Architecture

This case study outlines Clariant's transition from a traditional MPLS network architecture to an internet-first network utilizing Tata Communications' IZO™ Hybrid WAN and IZO™ Multi Cloud Connect. Clariant, a multinational specialty chemicals company, required a solution to connect over 200 applications and multiple distributed cloud data centers while maintaining performance comparable to MPLS VPN. The document details the challenges faced, including adherence to complex internet regulations in various countries and the need for a seamless migration with minimal downtime. It describes the consultative approach taken to ensure effective network architecture planning, which included deterministic routing to AWS and compliance with legal regulations. The successful implementation resulted in high customer satisfaction, stable network architecture, and the seamless migration of global contact center voice services to the cloud. The case study emphasizes the importance of strategic planning and execution in achieving technical and commercial goals during the transformation process.
