​What is Composable Infrastructure?

Programmable infrastructure refers to infrastructure components that can be disaggregated and composed together in software to meet changing business needs. With programmable infrastructure, discrete pieces of hardware such as servers, storage and networking can be pooled together and their resources allocated on demand through automation. This allows infrastructure to be composed and recomposed in any configuration instantly through an API.

Benefits of Composable Infrastructure

Programmable infrastructure provides several benefits over traditional rigid infrastructure models:

Increased Agility and Speed: Programmable Composable Infrastructure allows resources to be provisioned and reconfigured in minutes rather than weeks. This dramatically improves agility and the speed at which infrastructure can be adapted to new workloads or business initiatives. Rigid, hardware-defined systems can take far longer to scale due to procurement delays.

Higher Hardware Utilization: By pooling infrastructure resources that can be assigned on demand, composable systems drive up utilization rates which were often low in traditional data centers. Underutilized servers can now offer their idle resources to other workloads, reducing hardware spending requirements over time.

Simplified Management: Composing infrastructure from software removes dependencies on specific hardware configurations. Resources across a distributed environment can be centrally managed from code and automated through APIs. This dramatically simplifies operational management compared to hardware-defined silos that require manual configuration.

Cost Savings: The ability toright-size infrastructure perfectly to changing usage patterns helps eliminate overprovisioning. Composability also extends hardware lifecycles by keeping equipment in use. Overall, these factors contribute to reduced infrastructure costs over time compared to traditional siloed models.

Enables New Use Cases: The agility, speed and programmability of programmable infrastructure unlock innovative new usage scenarios that were difficult to fulfill before. Edge computing, microservices architectures, internal platform-as-a-service models and Kubernetes deployments can all leverage composability to composite and adapt resources on demand.

Infrastructure Platforms for Composability

Severalvendor platforms now aim to deliver programmable infrastructure through abstraction of discrete resources into software-defined pools:

Nutanix Frame: Nutanix'scomposable offering builds on its hyperconverged infrastructure software. Frame pools server, storage and virtualization resources that can be flexibly assigned through the company's Prism management interface.

Cisco Intersight: Cisco's cloud-based management platform Intersight enables composability across Cisco and third-party infrastructure. It pools server, network and storage hardware to be disaggregated and assigned on demand through the API.

HPE Synergy: HPE's programmable infrastructure platform pools compute, storage, and fabric resources which can be dynamically assigned as virtual devices or entire virtual systems using the HPE OneViewmanagement tool.

VMware Cloud Foundation: VMware's integrated stack delivers compute abstraction through VMware vSphere and storage abstraction with VMware vSANTM. IT resources from various vendors can be pooled and centrally managed as a service.

Red Hat OpenShift: The OpenShift container platform and OpenStack IaaS together form Red Hat's approach to delivering infrastructure resources on demand. Users self-select resources through an API that dynamically allocates capacity.

Challenges for Adoption

While offering clear benefits,programmable infrastructure adoption does face some challenges organizations need to overcome:

Hardware Integration: Current solutions focus on specific vendor’s hardware which requires compatible components and lock-in. Interoperability between gear from different suppliers remains limited.

Management Transition: Moving from rigidly defined infrastructure to a composable model requires adapting operational processes and tools. New automation, orchestration and management skills need developing.

Application Transition: Existing monolithic applications and workloads were often built around fixed infrastructure assumptions. Retrofitting comprehensive monitoring and adaptability requires application changes.

Security Concerns: Composability’s rapid reconfiguration introduces new attack surfaces if not implemented securely. Strong access controls, immutability, encryption and micro-segmentation are vital but increase complexity.

Cost and ROI: While total costs may decrease long-term, the initial hardware investment in a composable solution can be higher than traditional silos. Convincing stakeholders requires proving ROI over traditional approaches.

Overcoming the challenges will take time and work, but programmable infrastructure ultimately promises to deliver the agility, efficiency and flexibility that modern digital businesses demand from their supporting IT systems. As industry standards for interoperability mature and management tools advance, composable models will see further adoption.
