Cloud Native Edition Enterprise Edition IBM Cloud Private deployment considerations Cloud Native Edition includes all of the capabilities of the Community Edition but allows for  high available clusters to exist to support a production on-premises cloud infrastructure. Also,  the services catalog is extended in such a way that key offerings, such as IBM Vulnerability  Advisor, are also available starting with this edition. Cloud Native is suited for enterprise  developers who want to modernize their applications manageability and operations. IBM Cloud Private Enterprise Edition further extends the previous editions and is suited for  enterprises to modernize and optimize applications while scaling their data centers to  securely work with cloud services. The services catalog is expanded to support more  enterprise products, such as IBM WebSphere Application Server Network Deployment, IBM  MQ Advanced, and IBM API Connectfi. IBM LinuxONE features unmatched scalability and security capabilities when compared to  traditional x86 workloads. LinuxONE systems can meet all of the hardware and software  requirements to deploy an on-premises cloud infrastructure within a single hardware footprint. The IBM Cloud Private is built in such a way that it is flexible to meet various demands. In that  sense, several architecture-specific decisions must be considered before proceeding with the  product installation process. As described in 7.6.3, “Deploying IBM Cloud Private on  LinuxONE” on page 230, it is necessary to understand the open source components that are  used by IBM Cloud Private and how they interact with each other. This understanding helps to  properly plan, size, and ensure that the cloud can meet the growth demands that are required  to scale your infrastructure. Along with the proper sizing and planning details that are specific to your IBM Cloud Private  cluster, the following other aspects must also be considered: IBM Cloud Private supports High Availability configurations to ensure that even the failure  of critical cloud components do not interrupt IT and business operations. The IBM  LinuxONE platform further uses this capability with z/VM Single System Image (SSI) and  Live Guest Relocation (LGR) capabilities. LGR allows for Linux guests to be  quickly relocated to other z/VM domains without any downtime, which ensures that the  cloud can continue to run even during maintenance that otherwise require downtime. A proper network topology is required for most cloud workloads. If possible, a highly  available external load balancer, such as an F5, can be used to spread the traffic among  separate master or proxy node instances in the cluster.  Such approach allows for your IBM Cloud Private cluster to coexist across different  subnets, which allows for continuous operation even when its primary network faces an  outage. Other considerations that are related to networking involve the capabilities of a  cluster to communicate with other IBM Cloud Private clusters, and other infrastructure  components that are external to the IBM Cloud Private infrastructure.  Under IBM LinuxONE, z/VM can provide VLAN Aware VSWITCH capabilities to allow the  cloud infrastructure to scale under different network segments within a single hardware  footprint.

To support an HA  solution, multiple master nodes must be deployed within a cluster. Chapter 7. Securing IBM Cloud Private and Microservices on LinuxONE  231
