Which cloud is better for international companies : Private Cloud-based services or Public Cloud-based services?

 Microsoft. While the fact that Microsoft leads the Cloud Wars Top 10 in cloud revenue with an annualized run rate of $15.2 billion, that’s not by any means the only reason it tops the list.

·        >Vertical markets—Salesforce says its deeply committed to deepening its industry expertise and solutions, and that early indications reveal huge potential.

·        >With an expanding product line touching on all customer-facing apps plus analytics and the new focus on verticals, Salesforce now has the goods with which to penetrate more deeply into existing and future customers.

·        >Artificial intelligence—Benioff is becoming perhaps the world’s leading evangelist for AI for the C-suite. After all, he says, Salesforce’s “Einstein” AI product has already made him a “better CEO.”

Reason why public clouds are better

·        Private clouds tend to use older technology than public clouds: You may have spent hundreds of thousands of dollars on new hardware and software, but try getting your organization to agree to that every year.

·        Public clouds shift capital expenses to operational expenses: It's pay as you go, versus building an entire datacenter, no matter how virtualized it may be.

·        Public clouds have better utilization rates: With private cloud, your organization still has to build and maintain all kinds of servers to meet spikes in demand across various divisions or functions. Public cloud offers the same spare demand on a pay-as-you-need-it basis.

·        Public clouds keep infrastructure costs low for new projects: With private clouds, you still need to scare up sometimes scarce on-site resources for unplanned projects that may pop up.

·        Public clouds offer greater elasticity: "You'll never consume all the capacity of a public cloud, but your private cloud is another matter entirely."

·        Public clouds get enterprises out of the "datacenter business": establishing private cloud probably gets you in deeper into the DC business than with traditional on-premises servers.

·        Public clouds have greater economies of scale: No private cloud can compete with the likes of Google and Amazon on price. And the public providers are constantly buying boatloads of the latest security technology.

·        Public clouds are hardened through continual hacking attempts: Thousands of hackers have been pounding Google and Amazon for years now. The public cloud providers are ready for anything at this point.

·        Public clouds attract the best security people available: They seek out the top security experts, will pay them top dollar, and treat them as the most important part of their businesses, which they are. Do traditional enterprises treat security teams this way?

·        Private clouds suffer from "perimeter complacency": "If it's on the internal network, it must be secure!" 'nuff said...

·        Private cloud staff competence is an unknown: Your organization may have a lot of talented and knowledgeable people, but is data security the main line of your business?

·        Private cloud penetration testing is insufficient: Even if you test your applications and networks on a regular basis (which man organizations don't), these only tell you if things are secure at that exact moment.

Cloud deployment model selection is an important for any type of business. The selection process could depends on business size, need and objectives. The management and IT should engage to discuss the best option that serves their business needs in terms of functionality, security and liability. Public cloud is a good choice for small size organizations and also for personal use. However the public cloud vendors couldn’t grantees all required levels of security and they can’t ensure user data protection. Thus, users should be spend some effort to manage their assets and resources to ensure data availability. For government or international organizations the private department model is more adequate because vendors have the responsibility of providing more services to protect organizations assets. Private deployment model also work on private network which provide higher level of security to help business and stackholders to to communicate securely and control their assets and business functions. The cost of private model is much higher than other models , therefore business should conduct assessment for the most adaptive services based on their budgets and other business requirements.
