Composable infrastructure represents a new approach to data center design that focuses on flexibility, scalability and efficiency. With composable infrastructure, resources like compute, storage and networking can be easily assembled, updated and redeployed as needed to support changing application requirements. This contrast traditional monolithic infrastructure models where hardware is fixed-function and difficult to adapt over time.

A Composable Infrastructure approach uses disaggregated resources that are pooled and centrally managed through software-defined controls. This allows individual components like servers, storage disks and network interfaces to be virtualized and shared dynamically among workloads. Resources can be instantly provisioned, reallocated or repurposed on demand through an API. Management is software-based rather than relying on manual reconfigurations of physical hardware.

Benefits of Composability

There are several key benefits that come with adopting a composable infrastructure model:

Increased Agility - Resources can be quickly and easily assembled into new application environments as needs change. There is no delay from ordering, installing and configuring fixed-function hardware appliances. IT is far more responsive to business demands.

Improved Hardware Utilization - With a flexible pool of shared resources, utilization rates are optimized through automated packing of workloads. Underutilized capacity in one area can support demand spikes elsewhere. This drives down capital and operating expenses over time.

Faster Innovation - New applications and technologies can be non-disruptively integrated using composable building blocks. Sandboxing lets teams experiment freely without risk to production. Innovation cycles are shortened.

Reduced Complexity - By decoupling software and hardware functions, the infrastructure is simplified. Management is handled through a single interface rather than an assortment of proprietary consoles from different vendors. Troubleshooting and changes become streamlined.

Elastic Capacity - Workloads automatically provision resources on-demand and release them when finished. Storage, memory, and other IOPS scale elastically rather abstracting physical constraints. Lifecycle costs are controlled as pay-as-you-grow purchasing replaces overprovisioning.
