High Availability and Healing

75%

  • The default HAProxy load balancer can be used to create a multi-master and multi-etcd cluster environment – with etcd nodes either forming their own cluster or deployed on the same node as the master

75%

  • Leverages native Kubernetes features to deliver HA and healing
  • Supports a variety of resilient load balancer options
  • Supports multi-master deployments
Deployment Model(s) Supported

75%

  • Public cloud (OpenShift Online)
  • SaaS-managed (OpenShift Dedicated)
  • Hybrid cloud (OpenShift Container Platform)

50%

  • Can manage Kubernetes clusters running on-premises and in Google Cloud and AWS (Azure support is in preview mode)
  • However, clusters must be managed through GKE
Prerequisites and Operating System Requirements

25%

Works only with Red Hat Enterprise Linux (a RHEL subscription is required and bundled into OpenShift)

100%

  • Supports all popular enterprise Linux distributions –
    • Red Hat,
    • CentOS,
    • Ubuntu
Monitoring and Operations Management

50%

  • Diagnostic tools via command line for health statistics
  • Prometheus and Grafana for environment health monitoring and visualization

50%

  • Uses Google Cloud’s Cloud Logging and Cloud Monitoring platforms by default to monitor clusters
  • Prometheus and Grafana may also be used
  • However, Cloud Logging and Cloud Monitoring are required if customers seek official support
Cluster Upgrades

50%

  • Can be automated with Ansible playbooks, or performed manually

75%

  • Clusters can be upgraded manually or automatically using methods supported by GKE
Multi-cluster Management

75%

  • A typical deployment creates a single Kubernetes cluster that is designed to scale up to 2000 nodes and 120,000 pods
  • All users of that deployment are expected to share that single cluster and achieve isolation via a combination of Kubernetes namespaces, and OpenShift multi-tenancy
  • Starting with OpenShift 4, multiple clusters can be managed through Red Hat’s hybrid cloud console

100%

  • Supports multi-cluster management and configuration
  • Clusters can span a range of on-premises or multi-cloud infrastructure
Multi-tenancy, Role-based Access Control, and Single Sign-on Support

50%

  • Delivers multi-tenancy through projects, called Kubernetes namespaces
  • Kubernetes RBAC is utilized to define granular access policies for users
  • There is no cross cluster multi-tenancy

100%

  • Uses native Kubernetes RBAC
  • RBAC settings can be managed centrally through Anthos Config Management
  • Full support for multi-tenant clusters
Private Registry Support and Image Management

50%

  • Relies primarily on built-in OpenShift registry. Can be used with third-party registries such as Docker Hub, but images must be imported manually on the command line

75%

  • No built-in registry service
  • Compatible with all standard Docker registries
Hybrid Cloud Integrations and APIs

75%

  • OpenShift Container Platform supports deployment on hybrid and multi-cloud environment. However, all infrastructure must be provisioned with RHEL

100%

  • Supports hybrid infrastructure built using a range of public clouds, private data centers and operating systems
  • However, requires use of Google Cloud services (GKE) for infrastructure management (even if clusters are deployed on other clouds or on-premises)
User Interface and Experience

100%

  • Provides a native UI that enables management of your Kubernetes resources and the catalog

75%

  • Provides a management dashboard as part of Google Cloud Console
Support for automated application deployments

75%

  • Application lifecycles can be managed through either OpenShift Ansible Broker or application templates (the latter support Rails, Django, Node.js, CakePHP, and Dancer)

50%

  • Applications can be deployed from Google Cloud Platform Marketplace
  • Applications can also be deployed using Helm charts or similar techniques using Anthos Config Management repos; however, this requires some manual setup
Production Grade Service Level Agreement

75%

  • 99.5% uptime for fully-managed clusters (OpenShift Dedicated)
  • Troubleshooting is handled via support tickets
  • Customers drive manual upgrades and any issues require support team engagement

75%

  • No advertised SLA for Anthos service
  • GKE clusters have 99.5% uptime guarantee
Ease of Setup, Installation, Continuous Use, Management, and Maintenance

50%

  • Installing and configuring OpenShift is a manual process that is Ansible-based
  • Several Ansible playbooks are required during the installation

50%

  • Requires setup of multiple tools. Manual setup and configuration process.
  • However, the Migrate for Anthos tool is available to simplify migration of existing containerized applications into Anthos-managed clusters
Networking Support and Integrations

100%

  • OpenShift provides CNI support and can integrate with any CNI based SDN
  • By default OpenShift SDN is deployed, which configures an overlay network using Open vSwitch (OVS)
  • Out-of-the-box third-party CNI plugins supported: Flannel, Nuage and Kuryr

100%

  • Works with networking options supported by GKE (Flannel, Calico)
  • Requires Cloud VPN or Interconnect on Google Cloud if connecting on-premises clusters to Anthos
Storage Support and Integrations

100%

  • Supports integration with network-based persistent storage using the Kubernetes persistent volume framework
  • Supports a wide variety of persistent storage endpoints such as NFS, GlusterFS, OpenStack Cinder, FlexVolume, VMware vSphere etc.

100%

  • Compatible with GKE-supported storage solutions (standard Kubernetes volumes and certain GCP storage services)
  • Storage add-ons can be deployed through Google Cloud Platform Marketplace
Self Service Provisioning

100%

  • Provides a self-service UI (OpenShift Web Console) that is separate from the default Kubernetes dashboard UI to enable self-service for developers and administrators

75%

  • Basic self-service options are available through the Anthos dashboard in Google Cloud Console
Support for CI/CD integrations

50%

  • Pipelines and build strategies simplify the creation and automation of dev/test and production pipelines
  • Ships out-of-the-box with a Jenkins build strategy and client plugin to create a Jenkins pipeline. However, the setup to create and configure production pipelines is manual and time-consuming
  • The pipeline build configuration creates a Jenkins master pod (if one doesn’t exist) and then automatically creates slave pods to scale jobs & assign different pods for jobs with different runtimes

75%

  • Any CI/CD tools that are compatible with GKE can deploy to clusters managed via Anthos
  • Cloud Build is Google Cloud’s native CI/CD solution, but most major third-party tools are supported as well
Free Managed Service Plan

75%

  • OpenShift Online Starter Plan available for free. Only runs on public clouds and not on private infrastructure. Sign up here.

0%

  • No advertised free trial
  • Can be used free of cost for testing (not production) purposes with up to 100 vCPUs. This policy is valid up to June 30, 2020.
