A standard flat vL3 domain permits databases functioning across multiple clusters, clouds, or hybrid setups to interact effortlessly for database replication purposes. Workloads belonging to various organizations can connect to a shared 'collaborative' Service Mesh, which enhances interactions between different companies. Each workload is confined to a specific connectivity domain, ensuring that only workloads within the same runtime domain can engage in that connectivity. Thus, Connectivity Domains are deeply intertwined with Runtime Domains. Nonetheless, a core tenet of Cloud Native architectures is to embrace Loose Coupling, which grants each workload the adaptability to obtain services from various providers as required. The particular Runtime Domain of a workload has no bearing on its communication necessities, signifying that workloads associated with the same application must maintain connectivity regardless of their geographical locations. This highlights the crucial role of inter-workload communication in maintaining operational efficiency. Ultimately, this strategy guarantees that the performance of applications and the ability to collaborate remain stable, irrespective of the underlying infrastructure complexities. By enabling such seamless integration, organizations can enhance their operational agility and responsiveness to changing demands.
