So, what are data center networks really built for? Short answer “applications”. Whether it is a public cloud provider, private enterprise, FSI or telco cloud - the nature of applications across each data center type impose a different set of demands on the underlying network infrastructure. A next generation architecture is one that is versatile yet modular enough to address these different application needs, whether these are HPC and Big Data, legacy or real-time content. A common architecture goal is for a unified and consolidated network design that can leverage standardized technology attributes and can integrate a versatile workload environment be it high performance bare metal servers to a microservices enabled container environment. This tutorial is aimed at an in-depth structured understanding of data center business and technical requirements and how EVPN-VXLAN constructs serve as a swiss-knife approach to achieve the same. Practical case study examples that translate theoretical concepts into building blocks for designing and automating multi-tenant data center deployments. Explore how a unified technology solution can help build a network that grows with increasing east-west traffic, seamlessly connects with the backbone for north-south communication while leveraging familiar protocol concepts to achieve security insertion. We will also go over operator issues with traffic optimization, multicast and BUM traffic handling and other common pitfalls. A final step would be to define requirements for a cohesive solution using a centralized controller that enables a data center network operator to leverage the same degree of agility and visibility for both the physical network and the application infrastructure to truly build a software-defined data center.
