Cloud applications come into contact with huge data volumes due to analytics, mobile and social media. Such environments can be managed in a cost-effective manner with the help of innovative SDS model from VMware. SDS or software-defined storage is not storage virtualization. Rather it is the way of separating storage hardware from storage capabilities and services. Let us dig a little deeper into this concept.

What is SDS?

Storage services offered by cloud providers can be dynamically created and delivered to every single VM (virtual machine). These can be further controlled by policy; this vision is defined in VMware's SDS model. It revolves around shifting of an operational model of storage from an ascending array-centric approach into a completely VM centric descending model. By following this definition, all storage services can be precisely lined up with demanding application requirements.

Some benefits of SDS:

1. Storage provisioning is faster and simpler in this model. There is no need to execute complex pre-configurations in infrastructure and data services. The appropriate storage service gets created dynamically.

2. Service levels are controlled from the core across heterogeneous resources. Additionally, they are adjusted with apps in a simple way and all the underlying service deliveries get dynamically adjusted.

3. Hard mapping of roles and troubleshooting responsibilities get eliminated. Rather automatic monitoring of policies gets implemented to simplify all operations.

4. Separable resources in the data plane are replaced without disrupting data services through a flexible resource management tactic.

5. Policy tiers get exposed to end-users because infrastructure teams define countless classes of services. There is better asset utilization.

Therefore, by separating cloud storage hardware from the provider's infrastructure management software, heterogeneous storage hardware can be purchased by enterprises. Moreover, issues like interoperability, unstable utilization of storage resources and manual resource inaccuracies get managed. Hence, a company can leverage numerous data-backup and restoration capabilities.
