What are the differences between cloud-hosted and on-premises Power11 platforms?

The IBM Power11 family is designed for consistent deployment across on‑premises environments, edge locations, and the IBM Cloud. Although these platforms share the same processor architecture, their operational model, scalability, AI acceleration capabilities, and workload placement characteristics differ significantly. These differences help organizations determine the optimal environment for each workload based on performance, latency, economics, compliance, and modernization strategy.

Overview of Power11 deployment models

The Power11 platform is available in three primary consumption models:

On‑premises edge and entry systems (e.g., S1112)

Installed in customer-controlled environments, typically used for IBM i, AIX, Linux, and CPU‑based inference at distributed sites or departmental deployments.

On‑premises midrange and high-end systems (e.g., Power E1150 and Power E1180)

Scalability-oriented platforms optimized for enterprise virtualization, SAP HANA, large AI inference, and high availability.

Cloud‑hosted Power11 in IBM Power Virtual Server (PowerVS)

A fully managed IBM Cloud service delivering Power11 virtual machines with rapid provisioning, consumption billing, automated DR options, and integration with cloud-native services.

Each model provides architectural consistency, but with different trade-offs around control, cost, acceleration, and operational responsibility.

Hardware and AI acceleration differences

All Power11 processors include Matrix Math Accelerator (MMA) units and enhanced SIMD vector engines. These provide a baseline of on‑chip AI acceleration across all deployment models.

However, off‑chip acceleration differs:

  • S1112 (on‑prem entry/edge): MMA and SIMD only; no support for IBM Spyre Accelerator; suitable for lightweight inference and CPU‑driven AI workloads

  • Midrange and High-End Power11 (E1150, E1180): MMA + SIMD; full Spyre accelerator support via PCIe Gen4 expansion drawers; suitable for LLM inference, multimodal workloads, large-context pipelines, and high-throughput analytics

  • PowerVS (cloud): MMA + SIMD within virtualized CPU instances; no Spyre accelerator availability in PowerVS; suitable for general AI workloads, training orchestration, and CPU inference

Thus, very large AI inference workloads requiring Spyre accelerators must run on compatible Power11 systems on‑premises. Lightweight inference, preprocessing, and embedding pipelines can run in the cloud or on S1112.

Scalability and performance considerations

Performance characteristics across deployment models remain architecturally consistent due to the shared Power11 processor design. The key differences relate to:

On‑Premises (S1112, E1150, E1180):

  • Deterministic local performance
  • Direct-attached NVMe and PCIe devices
  • Dedicated memory bandwidth
  • Hardware accelerators (Spyre on select models)
  • Suitable for latency-sensitive and mission-critical workloads

Cloud (PowerVS):

  • Capacity scales elastically
  • Provisions new Power11 VMs in under 10 minutes
  • Shared infrastructure introduces virtualization layers
  • Uses cloud-native storage and networking constructs
  • Ideal for burst capacity, DR, dev/test, and modernization

No published CPU performance penalty exists in PowerVS versus on-premises, but I/O and network latency depend on the cloud region and WAN connectivity.

Operational and management differences

On‑Premises (S1112, E1150, E1180):

Customer manages:

  • Hardware lifecycle

  • Firmware updates

  • Physical security

  • Networking and storage

  • Full control over environment configuration

  • Required for regulated or air‑gapped workloads

  • Supports advanced RAS features (Power E1180: up to 99.9999% availability)

Cloud‑Hosted Power11 (PowerVS):

IBM manages:

  • Hardware

  • Power supplies and fans

  • Racks, networking, storage

  • Firmware lifecycle

  • Infrastructure security

  • Customers manage OS, applications, and middleware

  • Single pane of management through IBM Cloud portal and APIs

  • Consistent experience across public cloud and PowerVS Private Cloud

In PowerVS Private Cloud, IBM installs the PowerVS pod inside the customer's data center and manages it through IBM Cloud Satellite, blending cloud operations with local data residency.

Cost and consumption differences

On‑Premises Power11:

  • Customers purchase hardware (CapEx)
  • Useful for predictable long-term workloads
  • Existing licensing models for AIX and IBM i apply
  • Highest control, lowest runaway-cost risk
  • Power Enterprise Pools 2.0 (PEP 2.0) provides shared capacity across participating Power11 systems and monitors both base and metered processor capacity across the pool, allowing organizations to optimize consumption while maintaining predictable operational costs

PowerVS (Cloud or Private Cloud):

  • Pay-as-you-use (OpEx)
  • Ideal for inconsistent or seasonal workloads
  • Rapid test environments with no hardware investment
  • Shared Processor Pools (SPPs) offer granular billing
  • Cloud services reduce operational overhead

The two models often complement each other in hybrid cloud deployments.

Data sovereignty, security, and compliance

On‑Premises Power11:

  • Full control of data residency
  • Required for:
    • Financial institutions
    • Government workloads
    • Healthcare data
    • Strict compliance regions
  • Zero WAN dependency for local processing

PowerVS:

  • Meets major compliance standards (SOC 2, HIPAA, PCI-DSS)
  • PowerVS offered in 22 global IBM data centers
  • Regional placement for data sovereignty
  • PowerVS Private Cloud ensures local data residency, cloud operations model, and no public internet dependency

Hybrid approaches allow customers to maintain sensitive data on-prem while scaling compute in the cloud.

Cloud-hosted and on‑premises Power11 platforms offer the same processor architecture but deliver fundamentally different operational characteristics. On‑premises systems — especially midrange and high-end Power11 models — provide maximum performance, resiliency, and control, especially for workloads requiring Spyre acceleration or strict data governance. The S1112 extends Power11 capabilities to the edge with a compact, efficient, and IBM i–friendly design.

PowerVS expands Power11 into the cloud, offering elastic capacity, modernization pathways, and rapid provisioning with full OS compatibility. By understanding these differences and aligning them with workload requirements, organizations can deploy Power11 where it delivers the greatest value across edge, on-premises, and cloud environments.

What is Red Hat OpenShift integration?

Red Hat OpenShift integration on the IBM Power S1112 enables organizations to deploy, orchestrate, and manage containerized workloads on the Power11 platform with enterprise-grade Kubernetes. By combining the performance and resiliency of Power11 with OpenShift's container management capabilities, organizations gain a unified, cloud-native environment that runs modern applications alongside traditional workloads such as IBM i, AIX, and Linux.

OpenShift integration means that the S1112 can operate as a fully supported OpenShift cluster node, whether as a single-node cluster for edge deployments or as a worker or control-plane node in a multi-node configuration. Because OpenShift is fully supported on IBM Power (ppc64le), organizations can run containerized applications directly on the S1112 using the same tools, CI/CD pipelines, operators, and governance frameworks as in the public cloud or larger data centers. This provides consistency across environments and enables a common operational model.

The Power S1112 is particularly well suited for OpenShift deployments in distributed environments due to its compact half‑width 2U form factor, low power consumption, and enterprise‑class RAS features. These characteristics make it ideal for edge‑site clusters, store locations, remote offices, or space‑constrained facilities where deploying a traditional multi‑rack OpenShift footprint is impractical. The system supports flexible deployment models, including rack‑mounted or standalone tower configurations, allowing OpenShift to be deployed wherever compute capacity is needed.

The integration of OpenShift on S1112 also enables the coexistence of containerized workloads with IBM i and AIX running on the same system. Using PowerVM virtualization, organizations can dedicate LPARs to Red Hat Enterprise Linux CoreOS (RHCOS) or RHEL for OpenShift nodes, while maintaining IBM i or AIX partitions for existing business workloads. This architecture allows low‑latency communication between containerized microservices and traditional enterprise applications, supporting modernization efforts without requiring replatforming.

OpenShift clusters deployed on S1112 follow the same architectural patterns as other platforms. A cluster typically includes three control plane nodes, two or more worker nodes, and a temporary bootstrap node used during installation. On Power, control plane and bootstrap nodes must run RHCOS, while worker nodes may run either RHCOS or RHEL. The S1112 can support these configurations depending on workload requirements, making it possible to deploy OpenShift clusters entirely on Power hardware or in multi‑architecture configurations with x86 worker nodes.

In addition to multi‑node deployments, the S1112 supports Single Node OpenShift (SNO), which consolidates the control plane and worker functions onto a single system. This is ideal for edge sites such as retail stores, manufacturing cells, or branch offices where local containerized applications are required but space and power are limited. SNO provides a full Kubernetes experience in an extremely small footprint, and the S1112's redundant power supply and high reliability make it well suited for production workloads in remote environments.

OpenShift integration on S1112 also enables organizations to run Red Hat OpenShift AI, a suite of capabilities that supports the development, training, deployment, and monitoring of AI models. This is especially valuable for use cases that require local AI inference near the source of data, such as machine vision, sensor analysis, or real‑time decision‑making. OpenShift AI is supported on the Power Architecture and can take advantage of Power11 CPU performance and MMA‑accelerated math operations.

The combination of OpenShift and IBM Power also provides access to IBM Cloud Pak solutions, each of which is built on Red Hat OpenShift and fully supported on Power. These Cloud Paks — including Cloud Pak for Applications, Cloud Pak for Data, Cloud Pak for Integration, and Cloud Pak for AIOps — allow organizations to modernize at their own pace and deploy enterprise-grade containerized middleware directly on the S1112. Because Cloud Paks run anywhere OpenShift is supported, workloads can be moved seamlessly between on-premises S1112 systems and PowerVS environments in the IBM Cloud.

Deployment of OpenShift on the S1112 follows the same RHEL and RHCOS lifecycle as OpenShift on any other platform. OpenShift 4.19 and later require RHEL 9.6-based CoreOS, and installation requirements, including networking, storage, and control plane design, are documented in Red Hat's official installation guides for Power. The S1112 provides sufficient CPU and memory resources to host small and medium-sized OpenShift clusters, especially in edge or departmental environments, while also supporting multi‑architecture deployments that combine ppc64le control-plane nodes with x86 or ARM worker nodes.

In essence, Red Hat OpenShift integration on the Power S1112 allows organizations to adopt a modern, cloud‑native application platform while preserving the strengths of their existing Power environment. It enables consistent deployment, automation, and management of containerized workloads across hybrid and multi‑cloud architectures, while delivering the performance, reliability, and security expected from IBM Power. For organizations looking to modernize applications, introduce microservices, deploy AI workloads, or extend cloud‑native capabilities to the edge, the S1112 provides a compact yet powerful platform fully aligned with Red Hat OpenShift's enterprise Kubernetes ecosystem.

Edge computing usage scenario on S1112

The explosive growth and increasing computing power of IoT devices have resulted in unprecedented volumes of data. Those data volumes continue to grow as 5G networks increase the number of connected mobile devices. In the past, the promise of cloud and AI was to automate and speed up innovation by driving actionable insight from data. But the unprecedented scale and complexity of data that is created by connected devices has outpaced network and infrastructure capabilities.

Sending all device-generated data to a centralized data center or the cloud causes bandwidth and latency issues. Edge computing offers a more efficient alternative. Data is processed and analyzed closer to the point where it is created. Because data does not traverse a network to a cloud or data center to be processed, latency is reduced. Edge computing and mobile edge computing on 5G networks enable faster and more comprehensive data analysis, which creates the opportunity for deeper insights, faster response times, and improved customer experiences.

Edge computing is a distributed computing framework that brings enterprise applications closer to data sources such as IoT devices or local edge servers. This proximity to data at its source can deliver strong business benefits, including faster insights, improved response times, and better bandwidth availability. Characteristically, edge is distributed, software defined, and flexible. The value of edge is the movement of computing resources to the physical location where data is created, transacted, or stored, thereby increasing enablement of business processes, decisions, and intelligence outside of the core IT environment.

Power S1112 benefits for edge computing with AI

The Power S1112 provides several features that make it an excellent choice for an edge computing environment. The Power S1112 provides an entry-level compute platform that brings benefits that are designed into the Power11 chip:

  • Built-in AI acceleration circuitry to run AI workloads without the requirement for expensive GPU cards
  • Built-in reliability, availability, and serviceability options to provide a highly available AI platform
  • Remote management capability through the integrated eBMC card

The small size and flexibility of the Power S1112 make it an ideal platform for edge computing locations with limited space and with minimal power requirements. The ability to be either rack mounted or configured as a stand-alone tower mode makes the Power S1112 a good candidate for use in the following environments:

  • In remote offices, stores, and manufacturing locations

    Organizations with distributed offices often need to run line‑of‑business applications, local databases, print services, or lightweight analytics functions on site. The S1112 can be installed in a small equipment closet or mounted under a desk in tower mode, providing a secure and reliable local compute platform. Its resilience ensures that operations continue even during network outages, and its small form factor enables deployment in locations that cannot accommodate traditional server hardware.

  • In manufacturing equipment management environments with IoT

    Manufacturing environments often host IoT devices, sensors, and equipment controllers that generate continuous streams of operational data. The S1112 can act as a near‑edge compute node to aggregate, process, and analyze this data in real time. The ability to operate safely with minimal power and cooling makes it suitable for plant‑floor deployment, while its resiliency ensures that operations remain online even with intermittent connectivity to a central data center.

  • In new locations with new applications designed for edge computing

    The S1112 supports new workloads designed for distributed computing models, including containerized applications, lightweight machine learning inference, and local data processing microservices. The system's ability to operate as a standalone tower or in high‑density rack configurations gives organizations flexibility to build modular, scalable edge clusters as demand grows.

  • As an alternative to potentially expensive cloud deployments for edge computing environments

    In some cases, pushing all computation to the cloud is either cost‑prohibitive or introduces unacceptable latency. The S1112 offers a compelling on‑premises alternative for running edge workloads while still supporting hybrid integration with cloud environments. This approach helps organizations maintain low-latency local operations, control data governance requirements, and selectively offload non‑critical workloads to cloud platforms.

Additional use cases

There are many additional use cases to consider as you look at future edge computing applications. Power11 customers can benefit from edge and remote computing in the following situations:

  • Endpoint Security and Surveillance
  • In-store Point-of-sales customer experience (scoring)
  • Edge and remote container-based applications
  • Healthcare patient monitoring
  • Manufacturing equipment management with IoT (IBM Maximo®)
  • Utilities for power grid optimization and reducing energy waste
  • Embedded solutions for OEM/ESA contracts and exploring opportunities with Linux-based ISVs focused on ROBO deployment
