Software Defined Networking

Software-defined Networking (SDN) makes cloud orchestration complete by providing better visibility and control of the underlying networks to (elastic) cloud applications. It simplifies network management and provisioning for new features/applications/services through the centralized SDN controller, thereby increasing business agility.

Cloud infrastructure (IaaS/PaaS/SaaS) providers can benefit from,

  • Traffic isolation between tenants by segregating the physical network into different logical networks handling different flows,
  • Better security and application performance, and
  • Significant reduction in CapEx and OpEx as a result of better infrastructure utilization, simplified provisioning and management.
