   Red Hat subscription model
   A 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

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

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
    

    View Slide

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).
    

    View Slide

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)
    

    View Slide

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.
    

    View Slide

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
    

    View Slide

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
    

    View Slide

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)
