Hyper-Converged infrastructure is a software-centric architecture tightly integrated to compute, networking and storing resources into a single system. Hyper-converged systems require at least three hardware nodes at a minimum for high availability, expanded later by adding more nodes according to requirement.
Why Hyper-Converged Infrastructure(HCI) is Important?
Hyper-Converged infrastructure consumes less space hence reducing the data centenership and maintenance reduces due to the number of nodes. Administrators burden reduces with the reduced number of nodes. The cost of heating and electricity decreases as the required number of nodes are running. It provides horizontal scaling to add more nodes in the cluster according to the requirement enabling users to start with the smaller cluster. In recent years there has been an increase in adopting the hyper-converged strategy in data centers using it in edge locations like local office locations. It is easier for smaller or midsize organizations to adopt Hyper-Converged infrastructure.

What are the benefits of Hyper-Converged Infrastructure?
A hyper-converged platform integrates compute, storage and networking with software-defined software that defines the operational aspects of that infrastructure. The general and traditional choice for orchestration is hypervisor for provisioning of resources like storage, compute and network.
Kubernetes also used for provisioning of resources. Kubernetes is an open-source container-orchestration system for automating deployment, scaling, and management of containerized applications. It sits between the application and the infrastructure, lets application workflows dynamically control storage, compute, and networking resources. Software-defined storage like Rook (Ceph) used for elastic storage. Ceph is scalable storage which can be scaled up to an Exabyte.
Expanded according to a requirement by adding more nodes. Kubernetes and Ceph both are open source solutions run on commodity hardware and avoiding any vendor lock-in. There are several software tools provided by hardware vendors depending on the server chosen.
Adoption of Hyper-converged infrastructure is relatively easy but while selecting hardware or software be aware the current and future requirements. It requires at least three nodes to get started with high availability. Choose orchestration platform which scales horizontally like OpenStack, Openshift or Kubernetes to run on commodity hardware with requiring any special hardware and avoids any vendor lock-in. Use of software-defined storage like Ceph or Glusterfs used for high availability and redundancy. It also runs on commodity hardware hence eliminating the need for specialized hardware.
Best Practices of Hyper-Converged Infrastructure
Use of software-defined storage technologies like Ceph, Glusterfs.
Use of open source orchestration tools like Kubernetes, Openshift or OpenStack. To avoid any vendor lock-in.
Use of commodity or open computation hardware.
Use of automation tools as much as possible.
Proper Monitoring and security setup.
