Chapter 5. Connectivity Link benefits Connectivity Link provides the following main business benefits: User-role oriented Gateway API is composed of API resources that correspond to the organizational roles of infrastructure owner, cluster operator, and application developer. Infrastructure owners and cluster operators are platform engineers who define how shared infrastructure can be used by many different non-coordinating application development teams. Application developers are responsible for creating and managing applications running in a cluster. For example, this includes creating APIs and managing application timeouts, request matching, and path routing to backends. Kubernetes-native Connectivity Link is designed to use Kubernetes-native features for resource efficiency and optimal use. These features can run on any public or private OpenShift cluster, offering multicloud and hybrid-cloud behavior by default. OpenShift is proven to be scalable, resilient, and highly available. Expressive configuration Gateway API resources provide built-in capabilities for header-based matching, traffic weighting, and other capabilities that are only currently possible in existing ingress standards by using custom annotations and custom code. This allows for more intelligent routing, security, and isolation of specific routes without the necessity of writing custom code. Portability Gateway API is an open source standard with many implementations, which is designed by using the concept of flexible conformance. This promotes a highly portable core API that still has flexibility and extensibility to support native capabilities of the environment and implementation. This enables the concepts and core resources to be consistent across implementation and environments, reducing complexity and increasing familiarity. Hybrid cloud and multicloud Connectivity Link includes the flexibility to deploy the same application to any OpenShift cluster hosted on a public or private cloud. This removes a singular dependency or a single point of failure by being tied to a specific cloud provider. For example, if one cloud provider is having network issues, you can switch your deployment and traffic to another cloud provider to minimize the impact on your customers. This provides high availability and disaster recovery and ensures that you are prepared for the unexpected and can establish uninterrupted service, so that your platforms and applications remain resilient. Infrastructure as code You can define your infrastructure by using code to ensure that it is version controlled, tested, and easily replicated. Automated scaling leverages OpenShift auto-scaling features to dynamically adjust resources based on workload demand. This also includes the ability to implement robust monitoring and logging solutions to gain full visibility into your OpenShift clusters. Modular and flexible The highly flexible and modular Connectivity Link architecture enables you to use the technologies and tools that you already have in place, while also allowing you to plug into the connectivity management platform for maximum effectiveness.
