De ce OmniVCloud?

According to Gartner, cloud computing is “a style of computing in which massively scalable IT resources are delivered as a service to one or multiple customers using Internet technologies.

For the last several years, the market has been evolving towards on-demand infrastructure provisioned on a flexible, pay-as-you-go basis, but the introduction of cloud computing offerings has radically accelerated innovation in this market.


The economic downturn has accelerated adoption of these offerings, due to the cost-savings that can be achieved by the move from physical to virtual services, and from purchasing for peak capacity to obtaining what you need only when you need it. The majority of hosting customers now obtain at least some of their infrastructure on-demand, and most new hosting contracts include on-demand services. This evolution has quickly changed the vendor landscape, bringing many new entrants to rapid prominence, as well as decreasing the relevance of hosters who have failed to make this shift.

Software as a Service (SaaS) – sometimes referred to as "software on demand," is software that is deployed over the internet and/or is deployed to run behind a firewall on a local area network or personal computer. The provider installs, manages and maintains the software. With SaaS, a provider licenses an application to customers as a service on demand, through a subscription, in a "pay-as-you-go" model.


Platform as a Service (PaaS) - is the delivery of a computing platform and solution stack as a service. PaaS offerings facilitate deployment of applications without the cost and complexity of buying and managing the underlying hardware and software and provisioning hosting capabilities, providing all of the facilities required to support the complete life cycle of building and delivering web applications and services entirely available from the Internet.


Security-as-a-service (SECaaS) - is an outsourcing model for security management. Typically, Security as a Service involves applications such as anti-virus software delivered over the Internet.


Infrastructure-as-a-Service (IaaS) - is a provision model in which an organization outsources the equipment used to support operations, including storage, hardware, servers and networking components. The service provider owns the equipment and is responsible for housing, running and maintaining it. The client typically pays on a per-use basis.

There are countless blogs dedicated to virtualization and Cloud Computing in general. These links below will launch you straight into the center of virtualization blogging on the VMware side of things.

 
VMware technology

VMware technology (and cloud computing because of it) has a very healthy blog scene, partially because of the community-centric mindset that VMware has always had.

The community outreach guy, John Troyer (@jtroyer on Twitter), is the man of the hour at VMware, making sure their blog has a healthy contribution rate and many contributors. He writes a blog posting himself now and then too.

From the main VMTN blog page, there are many employee as well as other virtualization related blogs.

You can find the VMTN blog aggregate at:

One of the main contributors to the VMTN blog has his own blog site as well. One of the most prolific bloggers about VMware I think I've ever seen, Duncan Epping (@DuncanYB on Twitter):

Jason Boche (@jasonboche on Twitter) is a nuts and bolts guy with a lot of experience with VMware and virtualization technology. He's been around since the early days of ESX Server:
