Red Hat OpenShift Virtualization is a feature integrated into the Red Hat OpenShift platform acting as Operator. It’s designed to allow organizations to run and manage both: virtual machines (VMs) and container workloads side by side. This capability provides a modern approach to infrastructure management, enabling seamless migration and operation of traditional VM workloads within a cloud-native environment.
Kubernetes CSI significantly enhances the flexibility and capability of storage management in Kubernetes environments. By providing a standardized interface for integrating various storage solutions, it empowers developers to leverage advanced storage features while maintaining robust application performance and reliability.
iSCSI (Internet Small Computer Systems Interface) is a network protocol that allows SCSI commands to be sent over TCP/IP networks. It enables the linking of data storage facilities, allowing users to access remote storage devices as if they were local.
OpenShift can utilize iSCSI for persistent storage, which is essential for stateful applications.
Red Hat Advanced Cluster Management for Kubernetes (ACM) is a solution designed to manage multiple Kubernetes clusters from a single interface. It provides centralized visibility, control and governance across hybrid and multi-cloud environments. It also improves application and cluster management.
After creating the cluster, default user kubeadmin was prepared to log in to the new environment. However, there are several more secure ways to access your Red Hat OpenShift cluster. You can use different identity providers like LDAP, Keystone, Google, GitHub or OpenID Connect. Another one is HTPasswd which seems to be easiest to configure and use.
One of the challenges that organizations and administrators need to be familiar is installing patches/updating the Red Hat OpenShift infrastructure. There are two ways to update a cluster: using Web Console or CLI. With both methods, you can achieve the same result and update is smooth.
etcd is a consistent, open-source and distributed key-value store used in Kubernetes to backing all cluster resources like: configuration data, state data or metadata.
Regular backups of etcd database are crucial habit for Kubernetes clusters. Red Hat OpenShift has build-in mechanism to achieve that.
Red Hat OpenShift Container Platform is a container Kubernetes platform. With OpenShift, organizations can automate application deployment and management.
RH Openshift can be run in a private cloud infrastructure directly on the bare metal servers and on the virtualization platforms like VMware, Nutanix or Openstack. Also, it’s possible to install OCP in the public clouds like AWS, Azure, GCP or Alibaba.
