Virtualization technologies and secure cloud on-demand services escalate the need of cloud orchestration. Numerous Cloud Service Providers enhance the orchestration of cloud services based on well-configured projects. Several factors make customers cross-fingered to host resources on cloud in terms of virtualization, security, cost, load balancing, resource deployment, utilization and more. High demand to on-cloud services tend towards security and policies. Google Kubernetes Engine migrates the resources from cloud to GKE and supports security policies. The major view of this study is to focus on the key issue in the design of the cluster and decisions towards network set up to secure user projects. Use of subnets and cluster design policies secure the cloud applications to a greater extent. The Kubernetes cluster architecture and design considerations are applied and implemented on GKE in GCP and the results are shown.
