Cloud based networking brings a significant operational paradigm shift for service providers. It is expected to bring increased agility, optimized use of infrastructure as well as reduced manual operations during the service lifecycle.
However, the flexibility comes with increased complexity. In the virtual world, services are made up of multiple small pieces of software each having their own lifecycles that need to be managed. While services are defined in service models describing the required components, their relations, and dependencies. Suddenly it’s not just one process or lifecycle that needs to be managed, it’s thousands.
For a service provider, the ability to manage this cloud-based networking becomes a problem. Hiring people is costly and hiring people with the skills to understand software components, is even more costly. The business case breaks down.
The cloud-based network business case is about achieving an optimal level of automation and ability to manage the highly complex operational environment. Intent based orchestration, that automates the full lifecycle management of services and their components, without having to manually script or create complex workflows, is key to achieve these targets and run commercially viable NFV services.
There are 3 important stages in achieving 100% automation.
