Although composable infrastructure is a fairly popular term in the forums of data centres, most people are unaware as to what it really means. Due to the massive progress that technology has made, confusing terms are now aplenty in the market. Composable infrastructure is a concept which is pioneered by Intel. Intel has been propounding it for quite a while now, through its revolutionary Rack Scale Design idea. It comprises of oodles of computers along with networking and storage paraphernalia, all compressed into high density racks. These racks are then interlinked through virtual servers, thus enabling applications to accelerate usage of processing resources as and when they need it. Its rise to prominence is partially due to the popularity of hyper converged infrastructure solutions. In order to discuss the specifics of composable infrastructure, one needs to understand the different kinds of infrastructure leveraged by IT companies currently.
If you are looking for a Hyper Converged Infrastructure vendor, look for Hitachi ICT Solutions. They have been in the industry for many years, and they have a ready support staff to answer your queries. Also, they have an experienced technical team.

In this article we shall discuss, what composable infrastructure is all about.
Introduction to the different kinds of infrastructure
• Hyper converged infrastructure: In this setup, the infrastructure is defined in virtual components rather than hardware components. In spite of being virtual in existence, the modules are similar in arrangement to converged infrastructure. The different virtual modules responsible for the various functions of the system, are all interlinked through a physical platform designed by solution vendors.
• Converged infrastructure: In this setup, the specifications are permanently fixed with little to no room for flexibility. As this is a hardware based setup, it interacts with the cloud and private systems through distinct terminals.
• Composable infrastructure: In this setup, everything is flexible. It comprises of multiple modules which can be interchanged depending on the need of the situation.
Composable infrastructure offers a distinct set of advantages
The popularity of composable infrastructure solutions is primarily attributed to its flexibility in functions. All the modules in it are completely programmable and are comprised of software. Enterprises which leverage composable infrastructure, will have absolute autonomy when it comes to reconfiguring resource usage. Everything from processing to storage can be customised based on the workflow requirements. Additionally, composable infrastructure is characterised by three distinct features. They are-
• Highly flexible pool of resources: Each and every resource is pooled together in a common platform to remove compatibility issues.
• Resource management via software specifications: Enterprises will be able to manage their resources via the software interface itself. This includes the lifecycle of resources as well.
• Unified interface: Composable infrastructure solutions are characterized by unified interface, thereby streamlining management.
