for running and managing containers at scale. In this eBook, we will review capabilities of Kubernetes, deploy Kubernetes with Rancher, then deploy and scale some sample multi-tier applications. But the pods can be accessed. This load balancing configuration is much easier to manage, and helps scale pods seamlessly. Volume A volume is a directory with data which is accessible to a container. provides cluster management for containerized workloads and simplifies container orchestration at scale. In this chapter, we looked at Kubernetes terminologies, and how Kubernetes can help companies adopt

preferred way for global organizations to build and modernize their applications and services at scale. The potential of containers and Kubernetes was evident when, in 2020, Gartner2 predicted that SUSE Rancher Hosted – a premium ‘white-glove’ service available to organizations looking to manage scale their Kubernetes environment without needing to manage the operational complexities. SUSE Rancher Copyright © SUSE 2022 10 To help manage clusters at scale, SUSE Rancher utilizes Fleet, an open source project that enables GitOps at scale. Built by the SUSE Rancher team, Fleet is designed to manage

................................... 9 How SUSE Rancher delivers production-grade Kubernetes at scale: ..................................... 10 Solution architecture ............................... extraordinary predictable performance for mission-critical workloads, while also providing resiliency at scale. The PowerFlex family provides a foundation that combines compute and high-performance storage resources architecture eliminates any hotspots and ensures consistency and simplicity over time. You can scale the system while linearly scaling performance from a minimum of four nodes to thousands of nodes

enable customers to build faster Increase operational efficiency when managing multiple workloads Scale environments at speed without compromising compliance and security with easy access to open-source
