I have noticed PSOD on ESXi host running with qlnativefc – 3.1.x Qlogic HBA driver.
Resolution: Update qlnativefc driver to 3.1.36.0 or higher and recommended accompanying firmware version.

There are three cloud models that you can subscribe according to business needs:
Private Cloud: Here, computing resources are deployed for one particular organization. This method is more used for internal business interactions. Where the computing resources can be governed, owned and operated by the same organization.
Public Cloud: This type of cloud is used usually for Business to Consumer type interactions. Here the computing resource is owned and governed by service provider and operated by government or an academic or business organization or it may an individuals .
Hybrid Cloud: This type of cloud can be used for both type of interactions – B2B (Business to Business) or B2C ( Business to Consumer). This deployment method is called hybrid cloud as the computing resources are bound together by both clouds models.

The three major Cloud Computing Offerings are
Software as a Service (SaaS)
Platform as a Service (PaaS)
Infrastructure as a Service (IaaS)
Different business use some or all of these components according to their requirement.
The potential for cost saving is the major reason of cloud services adoption by many organizations. Cloud computing gives the freedom to use services as per the requirement and pay only for what you use. Due to cloud computing it has become possible to run IT operations as a outsourced unit without much in-house resources.
Following are the benefits of cloud computing:
Lower IT infrastructure and computer costs for users
Improved performance
Fewer Maintenance issues
Instant software updates
Improved compatibility between Operating systems
Backup and recovery
Performance and Scalability
Increased storage capacity
Increase data safety
With increase in computer and Mobile user’s, data storage has become a priority in all fields. Large and small-scale businesses today thrive on their data & they spent a huge amount of money to maintain this data. It requires a strong IT support and a storage hub. Not all businesses can afford high cost of in-house IT infrastructure and back up support services. For them Cloud Computing is a cheaper solution. Perhaps its efficiency in storing data, computation and less maintenance cost has succeeded to attract even bigger businesses as well.
Cloud computing decreases the hardware and software demand from the user’s side. The only thing that user must be able to run is the cloud computing systems interface software, which can be as simple as Web browser, and the Cloud network takes care of the rest. We all have experienced cloud computing at some instant of time, some of the popular cloud services we have used or we are still using are mail services like gmail, hotmail or yahoo etc.
While accessing e-mail service our data is stored on cloud server and not on our computer. The technology and infrastructure behind the cloud is invisible. It is less important whether cloud services are based on HTTP, XML, Ruby, PHP or other specific technologies as far as it is user friendly and functional. An individual user can connect to cloud system from his/her own devices like desktop, laptop or mobile.
Cloud computing harnesses small business effectively having limited resources, it gives small businesses access to the technologies that previously were out of their reach. Cloud computing helps small businesses to convert their maintenance cost into profit. Let’s see how?
In an in-house IT server, you have to pay a lot of attention and ensure that there are no flaws into the system so that it runs smoothly. And in case of any technical glitch you are completely responsible; it will seek a lot of attention, time and money for repair. Whereas, in cloud computing, the service provider takes the complete responsibility of the complication and the technical faults.
