Battle of the Clouds: Public vs. Private Cloud Hosting

Shared Cloud, also called Public Cloud, is a multitenant environment where all of your data resides in a shared storage network. All virtual hosting accounts share the same computing resources of all the servers in that system.

Private Cloud, also called Dedicated Cloud, is only accessible to users or partners of a single organization and all services are provided behind a secure firewall. All virtual hosting accounts possess their own server with exclusive access to all resources in that system.

Advantages of each:

Public Cloud: Less expensive. Standardized environment with no need for architecting a unique environment. High level of scalability.

Private Cloud: A server all your own which provides more control and customization capabilities. Each private cloud is built to fit the business. Enterprise-grade security and reliability. High level of scalability.

Disadvantages of each:

Public Cloud: Lack of control. Little to no customization. Not as fast. No dedicated resources. Problems with the system result in interruptions and restrictions of all accounts on the server.

Private Cloud: More expensive. Require setup.

Explain how hosting your private cloud eliminates all the hardware and maintenance that would be necessary in-house. It also adds a level of expertise and experience to the setup and deployment and ongoing support. And while the cost is higher with a dedicated cloud infrastructure, it is broken down into predictable monthly or annual costs.

Common public clouds include Amazon, Azure and Office 365. Common private clouds include yours truly. Here is the out-of-box functionality missing in most public clouds:

  • Business Intelligence
  • SSRS, PowerPivot, PerformancePoint
  • Search Driven Websites
  • Business Connectivity for LOB data integration
  • Central Admin Access
  • Reduces platform’s extensibility & ability
  • Server-side APIs
  • Production Internet website capabilities

Here is what is readily available in the private cloud:

  • Full admin control over your SharePoint infrastructure
  • Financially backed 100% uptime SLA
  • Active directory integration over VPN or ADFS
  • Compliant-ready SharePoint farms with isolated data
  • Custom disaster recovery backups to fit your needs
  • Cost-effective solutions based on your requirements
  • Provides or can use Microsoft SharePoint licensing
  • 24/7/365 Availability for SharePoint Expertise

Why do you want full control and functionality?

First of all, why limit yourself in any way if you don’t have to? Private cloud gives you full functionality which means that you can control whatever goes on with your server. You can make changes that help your business, like implementing third party app solutions to your infrastructure. Your IT team remains an administrator and can log into your servers and customize your private cloud with full access.

Bottom line: A private cloud is completely customizable, full functional and always accessible. All at a cost savings to your enterprise.

Why do you want unlimited customization of your cloud?

Same reason. Full control and also to add third party tools that can build a better solution for your specific needs. Complete customization extends to the design and development you use when creating your website. It extends to the web parts that you can deploy across your entire farm. It extends to the integration options that private cloud’s full network integration and custom web service capabilities allows. Capacity is not a problem with a customized solution that grows as you do. It also extends to building versioned farm solutions with the capability to update web.configs and back end databases. It even extends to workflows where you can create custom workflow actions to integrate with line-of-business systems. So unlimited customization capabilities becomes a pretty critical resource that some cloud users aren’t even aware they could possess.

Bottom line: Unlimited customization is the only way you can build your server your way.

So, what’s the catch? Why doesn’t everyone choose private or public cloud?

Well, everyone loves maintaining control, but they don’t love maintenance. If your private cloud is built using resources from your own datacenter, it leaves you to shoulder the management as well. And that can turn a lot of people off. They’d rather it live somewhere else so they don’t have to manage it, even if that means losing control.

What most businesses don’t realize is that they can host their data in a private cloud and get the control without the management role. Hosted private clouds like’s SharePoint Cloud give you the full functionality and control while leaving all of the backups, maintenance, patching and support to our SharePoint experts so your business is free to focus on the next big thing.

There is, however, a way to balance the best of both worlds, which we will learn about in our next Fpwebinar entitled “Understanding the Hybrid Cloud”…
