Cloud infrastructures have gone through an impressive evolution over the last decade. The demand towards more flexibility, operational agility and predictability urged vendors to strive for tighter integration of compute, storage, virtualization and network silos needed to support a cloud model.
Back in 2007, converged infrastructures were, in essence, bundles of server, storage and network products, sold with management software that facilitates the provisioning and management of the combined units. These infrastructures could be delivered as integrated appliances or as integrated reference architecture, and were, the first step towards advanced cloud infrastructures of today. However, these systems were extremely difficult to deploy and operate, and their support required excessive expenses.
The emergence of the hyperconverged model in 2012 transformed cloud infrastructures’ framework. By integrating storage and compute capacities into a single silo, hyperconvergence eliminated the need for a storage area network (SAN). Its storage functions and optional capabilities like backup, recovery, replication, deduplication and compression are delivered via software in the server node.
The simplicity of these systems, ease of deployment and cost-effectiveness accounts for their growing popularity; however, they still have a number of serious limitations. The weakest spot of cloud infrastructures based on the hyperconverged model is the network. Most HCI systems provide no network virtualization, which results in poor manageability, limited network mobility and scalability, and security blind spots.
2016 witnessed the start of a new era. The introduction of the superconverged model goes beyond hyperconverged infrastructures by tightly integrating network, storage, compute, virtualization, and SaaS management into a single platform. The Cloudistics Ignite superconverged platform offers the simplicity of hyperconvergence, but with a complete software-defined datacenter, including the network. That means better performance, easier deployment, and lower total cost of ownership.
This infographic looks at the evolution of cloud infrastructures since the introduction of the first converged datacenter in 2007, and illustrates key features of converged, hyperconverged and superconverged models along with their specifics and benefits.
