What Is Private Cloud (Internal Cloud or Corporate Cloud)

Private Cloud Is A Type Of Cloud Computing That Delivers Similar Advantages To Public Cloud, Including Scalability And Self-Service, But Through A Proprietary Architecture. Unlike Public Clouds, Which Deliver Services To Multiple Organizations, A Private Cloud Is Dedicated To A Single Organization.

As A Result, Private Cloud Is Best For Businesses With Dynamic Or Unpredictable Computing Needs That Require Direct Control Over Their Environments.
Public and Private Cloud Deployment Models Differ. Public Clouds, Such As Those From Amazon Web Services Or Google Compute Engine, Share A Computing Infrastructure Across Different Users, Business Units Or Businesses. However, These Shared Computing Environments Aren't Suitable For All Businesses, Such As Those With Mission-Critical Workloads, Security Concerns, Uptime Requirements Or Management Demands. Instead, These Businesses Can Provision A Portion Of Their Existing Data Center As An On-Premises -- Or Private -- Cloud.

A Private Cloud Provides The Same Basic Benefits Of Public Cloud. These Include Self-Service And Scalability; Multi-Tenancy; The Ability To Provision Machines; Changing Computing Resources On-Demand; And Creating Multiple Machines For Complex Computing Jobs, Such As Big Data. Chargeback Tools Track Computing Usage, And Business Units Pay Only For the Resources They Use.

In Addition, Private Cloud Offers Hosted Services To A Limited Number Of People Behind A Firewall, So It Minimizes The Security Concerns Some Organizations Have Around Cloud. Private Cloud Also Gives Companies Direct Control Over Their Data.

But Private Clouds Have Some Disadvantages. For Example, On-Premises IT -- Rather Than A Third-Party Cloud Provider -- Is Responsible For Managing The Private Cloud. As A Result, Private Cloud Deployments Carry the Same Staffing, Management, Maintenance and Capital Expenses as Traditional Data Center Ownership. Additional Private Cloud Expenses Include Virtualization, Cloud Software And Cloud Management Tools.

However, To Reduce An Organization's On-Premises IT Footprint, Cloud Providers, Such As Rackspace And Vmware, Can Deploy Private Cloud Infrastructures.

A Business Can Also Use A Mix Of A Private And Public Cloud Services With Hybrid Cloud Deployment. This Allows Users To Scale Computing Requirements Beyond The Private Cloud And Into The Public Cloud -- A Capability Called Cloud Bursting.

Samsung's latest ATIV laptop gets a 4K screen, discrete graphics

Samsung's ATIV Book 9 series has mostly targeted Ultrabook buyers with lighweight, powerful and pricey models like the ATIV Book 9 Plus. However, the company's latest model, the ATIV Book 9 Pro is now suited for demanding users like gamers and graphics pros, thanks to workstation-class specs. It's equipped with the latest sixth-gen Intel Core i7 CPUs, a 15.6-inch 4K display with optional NVIDIA GeForce GTX 950M graphics and 6.5 hours of battery life, all squeezed into a 4.45 pound all-aluminum body. Like other ATIV Book 9 models, it also features a slim, tapered front profile.

Other features include 8GB of RAM, a 256GB SSD, reversible USB Type C port, quad speakers and a WiFi booster. Samsung is clearly targeting MacBook Pro 15 and Dell XPS 15 buyers, with a price to match at $1,599. Microsoft's Surface Book is in the same performance class, but it's hard to justify that model's $2,699 top price (with discrete graphics and an Intel Core-i7 CPU) unless you need the tablet and convertible option. If you need a Windows 10 laptop with a touchscreen, however, it will be a tough choice between the very similar models from Samsung and Dell.

 

Samsung hasn't forgotten Ultrabook users, as it's also launching the ATIV Book 9 Spin convertible. That model features a 360-degree detachable screen with laptop, tented screen and tablet modes. It's as well-equipped as you'd expect for a $1,399 convertible Ultrabook, with a 13.3-inch QHD+ (3,200 x 1,800) screen, Intel Core i7 CPU and 8GB of RAM. It also has an all-aluminum shell, but weighs a lot less than its more powerful sibling at 2.87 pounds. Both the Book 9 Spin and Pro models feature Samsung's "outdoor mode," which cranks brightness up to 700 nits in exchange for less battery life. The models will arrive sometime this month exclusively at Samsung.com and Best Buy.
