This customer case study explores the successful network transformation undertaken by a rapidly growing managed service provider seeking enhanced agility, visibility, and scalability. Their migration to an open-source network solution yielded remarkable results. The company achieved an automated, intent-based, and secure containerized network that efficiently supported its business growth while significantly reducing the total cost of ownership. The adoption of an enterprise-level distribution of SONiC empowered them with a flexible, API-based orchestration, and telemetry-enabled fabric, offering full control of the technology stack without vendor lock-in. The partnership with Dell Technologies provided seamless implementation and migration, resulting in greater confidence and satisfaction for them in their network modernization journey. With Dell Technologies' ongoing support, they envisions scaling its SONiC deployment to over 100 racks, driving continuous innovation, and meeting the demands of a competitive market with ease.
