Over the past decade, the focus for tech startups has shifted from speed to agility, emphasizing the ability to swiftly replicate and adopt market innovations while maintaining existing systems and practices. Agility involves leveraging existing momentum and integrating legacy systems with modern architectures. This can be achieved using service meshes like Kuma or Kong Mesh, which enable connectivity across varied environments and protocols, facilitating the transition from monolithic to microservices architectures. An example illustrates this by detailing how a service mesh can connect a legacy VM-based natural language processor to a Kubernetes environment, allowing for continued operation and gradual integration despite internal challenges. This approach provides temporary solutions and preserves policy enforcement and connectivity, highlighting the strategic importance of maintaining service connectivity to enhance business agility.
