Private vs Public vs Hybrid Cloud Considerations

Today we are going to discuss a few Private, Public, and Hybrid Cloud considerations leveraging cloud platforms such as Microsoft Azure and AWS.

Private cloud is defined as “cloud infrastructure operated solely for a single organization, whether managed internally or by a third-party, and hosted either internally or externally.” In the same breath public cloud is defined as “when the services are rendered over a network that is open for public use. Public cloud services may be free. ” Lastly hybrid cloud is defined as “Hybrid cloud is a composition of two or more clouds (private, community or public) that remain distinct entities but are bound together, offering the benefits of multiple deployment models. Hybrid cloud can also mean the ability to connect collocation, managed and/or dedicated services with cloud resources.” (Wiki Definition)

What does this mean to the consumer? Essentially it is ultimately the cost and the business’ requirements that help define where in the cloud spectrum you see your business participating in. Questions that you should be asking are: Where is our current capital spend as it pertains to infrastructure? Are we at the beginning or end of the life cycle of hardware and software procurement? Does our current disaster recovery plan satisfy our industry’s business continuity plan requirements? Are our resources best served engaging the role of business analysts or performing IT infrastructure tasks? How is our internal/external customer experience affected by a move to the cloud?

Questions and challenges like these beset most CIOs and Directors of Technology moving towards cloud. Navigating through these decisions can be somewhat daunting. The start of the process is to get a baseline set of requirements. Not to sound too consultative, but based on our experience, the companies that find the greatest success migrating to the cloud have a very good sense and vision of their base needs vs. wants. Navigating through the different narratives of cloud can be a very daunting task as well. Amazon Web Services and Microsoft Azure are currently the market leaders in the cloud space. Both solutions offer very robust options. There are distinct differences between the two offerings. One major difference is how they approach their respective SLAs at the data center and virtual server layers. Some of the following considerations you should present to your potential cloud provider are as follows:

  • Email/Phone Support/Ticketing system.
    • Understand the different levels and response times. How does their support model line up with your own service level agreement with your business units?
    • What other call centers will you be conversing with. Is it domestic/global?
    • Hours of support? Response time?
  • Industry certifications
    • Does your cloud partner hold known certifications SAE16, PCI, HIPPA, etc….
    • At what level do they hold this certifications? At the organization level or simply the brick and mortar (data center)?



  • Data Center offering
    • SLA (Service Level Agreement) offered?
    • Locally/Geographically redundant?
    • Global footprint?
    • Number of tiered providers?
    • What direct connections do they have with public cloud offerings?
  • Roles and Responsibilities
    • Clearly understand the roles and responsibilities between the respective support verticals.
      • Client/End-Point
      • Server
      • Application
      • Database
      • Network
      • Physical Security
    • How will this affect the existing systems that are kept on premise?
  • Changes in current Infrastructure
    • What changes in my network infrastructure do I need to implement as a result of moving to the cloud. Even though you may be reducing your infrastructure foot print as it pertains to computing, it may increase incrementally in other areas of your network. i.e. Internet connectivity redundancy at the local site.
    • Licensing considerations. What is mobile and what is static?


Microsoft Azure and AWS platforms offer scalable and cost effective solutions that help increase productivity and security. The landscape of how we access our systems is rapidly expanding. Companies are quickly learning the need for private, public, and hybrid cloud solutions is only going to exponentially increase in the near future. Make it easier on yourself. Explore and understand your options.
