The Private Cloud Is Dead By @XOComm | @CloudExpo [#Cloud]
There's a critical misconception about the private cloud still making the rounds even after years of corporate adoption

Depending on whom you listen to, the private cloud is either dead or on the cusp of a major market breakthrough. Some tech pundits argue this technology has already been replaced by more efficient public cloud offerings and businesses just need time to catch up, while others claim there's a bright future for private solutions.
Research supports the latter - according to IDC, spending on hosted private cloud services should hit $24 billion by 2016. Why? Because there's real value in this model. Here's a look at five compelling advantages of the private cloud.
It's Not On-Premises (Necessarily)
In fact, the difference between private and public doesn't rest with resource location but with how these resources are distributed. On-premises and dedicated private cloud models offer a 1:1 service ratio - all compute power is available to a single company. Virtual private clouds (VPCs), meanwhile, operate much like virtual private servers (VPS), giving companies more control over security and access but still drawing from a pool of shared resources.
Put simply, one critical advantage of the private cloud is flexibility: it can be on-premises, off-site, 1:1 or part of a virtualized server.
It's More Secure
Nonetheless, private clouds come out on top. Why? Because in the private model, companies have direct control over data access and permissions, which means more than just defining who can look at what data, when and why. Whether on-premises or off-site, the granular control offered by private clouds provides the security visibility missing from provider-handled public defenses.
It's Ideal for "Certain" Apps
In some cases, applications are designed to run within limited network parameters. Financial apps, risk management solutions or HR data handling apps don't benefit from wide-open space and may in fact do worse on public hardware. Unified communications (UC) technology is another good example if you're running a cloud-based PBX or SIP trunking system; you don't want high-level conference calls and video chats routed through public channels.
It's About Data Sovereignty
Ultimately, companies want data sovereignty: control over data storage, movement and replication. Leveraging public cloud resources means giving up a measure of this control for better infrastructure access. Private clouds offer the same access without the need to hand over your data.
It's Going Open Source
Is the private cloud dead? As an on-premises only, local IT-managed offering, absolutely. As a scalable, secure, sovereign and open-source alternative, not even close.
