The types of private cloud are: 1. On-premises private cloud, which provides the abstraction and standardization advantages of cloud computing, although the capacity is limited to the available infrastructure; 2. Hosted private cloud, a small part of the market is composed of It consists of a hosted private cloud, typically combined with hardware/software bundles, located at the user's location; 3. To build a private cloud, you can use proprietary resources to build a private cloud yourself, or you can use pre-packaged cloud infrastructure, such as OpenStack.
What types of private clouds are there
1. Local private cloud
Local private cloud provides Take advantage of the abstraction and standardization benefits of cloud computing, although capacity is limited to the available infrastructure. This organization is responsible for the entire stack, from data center to hardware to management, and the application code that runs on it. Private infrastructure racks are physically isolated and therefore naturally separate different computing workloads. Therefore, these environments are suitable for private clouds.
These types of on-premises private clouds use a common architecture built on OpenStack, Eucalyptus, Nutanix or other frameworks. Heavily virtualized IT systems, often built on VMware software, are common and offer many of the same benefits as private clouds, such as elastic resource consumption.
2. Hosted Private Cloud
A small part of the market consists of hosted private clouds, typically combined hardware/software bundles, located at the user's location. But the biggest difference from other types is that it is managed by the vendor. In this type, the provider provides support, maintenance, upgrades and even remotely manages the private cloud. This is one approach for enterprises, but shifts all the private cloud responsibility to the service provider. Sometimes vendors even offer services further up the stack, such as managing software applications running on the cloud.
Hosted private cloud providers such as: Citrix, Cisco, CSC, Dell, EMC, HP, IBM, Mirantis, Rackspace.
3. Building a private cloud
Cloud infrastructure refers to the components required for cloud computing. Whether it's a private cloud, a public cloud, or a combination of the two, the basic elements of cloud infrastructure are the same.
All clouds require an operating system like Linux, but their infrastructure can include a variety of bare metal, virtualized or container software that abstracts, pools and shares scalable resources across the network.
You can build a private cloud yourself using proprietary resources, or you can use prepackaged cloud infrastructure such as OpenStack.
