Cloud storage in the private cloud revolves around a few crucial requirements and components you should be aware of. The private cloud depends on the utilization of container platforms as well as the impact on storage located in the data center. When many people think about the term cloud storage, they tend to picture a more public construct like the ones offered by big names in the industry, such as Amazon and Microsoft Azure.
In fact, it is quite the contrary with private clouds. Private clouds tend to refer to more of an on premise construct that operates much like the public cloud, while offering easy access to required resources on a service-based distribution model. Whether a cloud is public or private, there are a number of criteria they must meet to be successful.
- Elasticity – This is the ability to scale up or down according to the users’ needs. Typically, from the perspective of the user, cloud resources are seen as unlimited. In private clouds a bit of budgeting occurs and resources are more constrained.
- Service-based – Resources here are delivered as services, with their definitions and concepts delivered from the hardware. Requests are made for virtual instances based on performance and inactivity needs.
- Multi-tenancy – The infrastructure must be able to support multiple different users, without the users being aware of or affected by others on the same platform.
- On-demand access – This enables you to request and maintain resources configured automatically by way of a portal or application programming interface (API).
- Billing & Reporting – These features enable the easy reporting of usage statistics, as well as billing performed at a higher level of granularity, which is typically done per hour or per day. It is important to remember that public cloud providers often charge by the hour, making it impractical for private infrastructure.
The Construct of Private Cloud Orchestration
A crucial part of the private cloud is the framework that supplies needed resources based upon customer requests. Included in framework are open-source platforms like CloudStack and OpenStack. Exclusive tools include VMware’s vRealize Suite Cloud Management Platform and the up and comer known as Azure Stack (Microsoft’s on premise automation suite application of public Azure).
Storage for the Private Cloud
When we observe the way our storage is consumed by the aforementioned platforms, there is a wide array of applications. Potentially, the most mature and easy to understand option when it comes to storage options is VMware. VMare vSphere is an essential part of the vRealize Suite. It supports a wide array of existing block and file based systems from Fibre Channel, iSCSI, and NFS based systems. Supplier support is extensive, and it can be provisioned out automatically as a part of a virtual machine creation.
Choosing the Correct Supplier
Choosing the right supplier or storage product calls for a fair amount of thought into the orchestration platform and the supportability that will be provided by the storage supplier. Remembering the main components of public cloud like the ones listed above will help you choose the most appropriate hosting tool for you.
