    Red Hat subscription entitles customers to download Red Hat tested and certified enterprise software. It also provides access to the guidance, stability, and security to confidently deploy these products, even in the most-critical environments. An active Red Hat subscription gives you continuous access to Red Hat software as it’s developed by Red Hat. Simply maintain one active subscription per resource running Red Hat software to take advantage of the value we provide.

  17. Subscription Types https://www.openshift.com/learn/sizing-subscription-guide 17 ▸ OpenShift subscriptions are only based

    on the number of hosts ▸ No cost per application ▸ No cost for memory footprint ▸ Unlimited right to use - can run as much workload as your environment will fit ▸ Subscription types for OpenShift: ▸ Core based (2 Cores or 4 vCPUs) ▸ Socket based for bare metal only (2 Sockets) ▸ OpenShift comes with Standard or Premium support ▸ These subscriptions can be stacked for a use-case where the end user needs to cover “bigger” hosts/VMs ▸ Red Hat OpenShift subscriptions can also be sold with Middleware via the OpenShift Middleware bundle SKUs

  20. Starter Suggestion 20

  21. A Package of Subscriptions to Help You Get Started OpenShift

    Starter Suggestion 21 While calculating sizing can be a useful exercise, sometimes you just want a pre-defined package to get started with. The following suggested bill of materials provides an extremely flexible, scale-able and versatile OpenShift environment designed to run in virtual machines and support hundreds of application containers. ▸ Qty 16: Red Hat OpenShift Container Platform Plus Premium (2 Cores or 4 vCPUs) ▸ Multi-master HA (3 VMs) ▸ Redundant infrastructure nodes (3 VMs) ▸ Application nodes (16 VMs) ▸ Multicluster management, advanced observability and policy compliance. ▸ Declarative security and active threat detection and response. ▸ Scalable global container registry. ▸ Qty 16: Red Hat OpenShift Data Foundation (previously known as Red Hat OpenShift Container Storage), Premium (2 Core) ▸ Adds scale-able block and file storage for applications inside OpenShift ▸ Qty 16: Red Hat JBoss Enterprise Application Platform for OpenShift Container Platform, Premium, 2-Core Premium ▸ Adds support for Java EE applications on OpenShift
  22. OpenShift Sizing 22

  23. Background and Terminology OpenShift Sizing 23 ▸ Terminology: ▸ Applications

    are packaged in container images ▸ Containers are grouped in Pods ▸ Pods run on Nodes ▸ Nodes are managed by Masters ▸ No-cost components: ▸ Control Plane Nodes (previously known as Masters) are included with a subscription ▸ Infrastructure nodes are included with a subscription ▸ May only host the following components: ▸ OpenShift registry. ▸ OpenShift Ingress Router. ▸ OpenShift monitoring. ▸ OpenShift log management. ▸ HAProxy-based instances used for cluster ingress. ▸ Red Hat Quay. ▸ Compact 3-Node Clusters ▸ A Compact 3-Node clusters is where the Master/Worker role are done on the same Node ▸ There is no special pricing for Compact 3-Node Clusters ▸ You simply count the cores on the 3 nodes *Infrastructure Node ▸ OpenShift Data Foundation ▸ Advanced Cluster Management ▸ Advanced Cluster Security ▸ OpenShift GitOps. ▸ OpenShift Pipelines. ▸ Custom and third-party monitoring agents. ▸ CN and CSI drivers and controllers ▸ Hardware or virtualization enablement accelerators ▸ Controller pods used for Kubernetes CRD or Operators (custom or third-party software).
  24. Clusters How many OpenShift clusters? Application Instances How many application

    instances (Pods)? Resource Consumption Total resource (memory/cpu) consumption across all application instances? Overhead How much overhead is required? Virtualized or BareMetal How big are your virtual machines or bare metal servers? . OpenShift Sizing Five Simple Questions 24 Using these questions, you can simply ballpark sizing for the OpenShift environment
  25. How Many Clusters? OpenShift Sizing 25 ▸ A cluster is

    a distinct/discrete OpenShift environment with its own set of masters and infrastructure hosts ▸ A customer determines whether or not they wish to have discrete/separated OpenShift clusters ▸ Dev, Stage, Prod ▸ High Availability and Disaster Recovery ▸ Cluster per “tenant” or LOB vs. many tenants sharing the same cluster ▸ What are you optimizing for: Utilization, Speed/Flexibility, Ability to change quickly ▸ Compliance and regulatory reasons ▸ Other reasons ▸ Each discrete OpenShift environment = 1 Cluster ▸ For highly-available clusters, 3 Masters are required. ▸ For highly-available infrastructure (Registry, Router, Logging, Metrics, etc), at least 3 Infrastructure Nodes are required. Example: Customer will run development, staging, and production applications in OpenShift inside a single HA OpenShift cluster (1 cluster - 3 masters, 3 infrastructure).
  26. How Many Application Instances (Pods)? OpenShift Sizing 26 ▸ Application

    instances run in pods ▸ Total number of application instances across relevant lifecycle environments must be totaled Example: Customer will run 1250 development and 250 production application instances (total: 1500)
  27. Total Resource Consumption? OpenShift Sizing 27 ▸ Either need to

    observe application memory usage or use existing settings (VM sizes, JVM heap sizes, etc) ▸ CPU Consumption needs to be calculated ▸ The more CPUs needed, the more nodes you’ll need, which translates to more cores. ▸ Greenfield environments may require an educated guess or reasonable starting point ▸ If you’re bundling Products, you’ll need to factor in for those minimum requirements in the consumption.* Example: Customer applications are consuming 2GB or less of memory per instance * Certain products are eligible to run on “infra” nodes and won’t count towards subscription sizing.
  28. How Much Overhead? OpenShift Sizing 28 ▸ Customers may have

    existing monitoring, security, or other agents on Nodes that consume resources ▸ OpenShift itself consumes resources that will not be available for applications (0.5GB is a good estimate) ▸ Calculate the total overhead of installed components on a host Example: Customer host applications consume 0.5GB of memory, and OpenShift consumes 0.5GB, for a total of 1GB of memory overhead
  29. Virtualized or Bare Metal OpenShift Sizing 29 ▸ Customers may

    have a standardized virtual machine size that they deploy ▸ Customers may have a standard hardware server that they deploy ▸ Determine memory and CPU/socket standard ▸ 1 subscription core covers 2 vCPU (1:2 when hyperthreading is enabled) Example: VMs have 64GB of memory and 4 vCPU
  30. Calculate Totals OpenShift Sizing 30 Using the examples from the

    previous steps: ▸ 1 Cluster with 3 Masters (all lifecycle environments in a single OpenShift) ▸ 2 Infrastructure Nodes (required for HA) ▸ Development Memory Footprint: 1250 * 2GB = 2500GB ▸ Production Memory Footprint: 250 * 2GB = 500GB ▸ Total Memory Footprint: 3000GB (2500 + 500) ▸ Virtual Machine Size: 64GB ▸ Virtual Machine vCPUs: 4 ▸ Overhead: 1GB ▸ Number of Application Nodes: 3000GB / (64GB - 1GB) = 47.6 -> 48 nodes ▸ Number of vCPUs: 48 x 4 = 192 ▸ Number of Cores: 192 / 2 = 96 ▸ Number of Core Subscriptions (2 cores per subscription): 96 / 2 = 48
  31. What’s in a Subscription OpenShift Container Platform 31 ▸ Red

    Hat Enterprise Linux / Red Hat Enterprise Linux CoreOS ▸ Red Hat Enterprise Linux CoreOS is available only with Red Hat OpenShift Container Platform. ▸ OpenShift subscription includes OCI-compatible open source container runtime and support ▸ OpenShift Container Platform ▸ Infrastructure components like Router and Registry ▸ Integrated log aggregation (Elasticsearch, Fluentd, Kibana)* ▸ Integrated metrics aggregation (Prometheus and Grafana)* ▸ Software Collections Library ▸ PHP, Python, Perl, Ruby, Node.js, .NET Core, MariaDB, MongoDB, MySQL, PostgreSQL, Redis, etc. ▸ JBoss Web Server ▸ Red Hat Build of Quarkus (for cloud-native Java development) ▸ Red Hat SSO ( keycloak) * Only supported as an integrated solution in the documented context. Limited customization. Not for general use.
