I along with so many IT professionals hate the term “Cloud” because it tends to be used for everything under the sun anymore. I wanted to take this post to go into what cloud actually is and what types of cloud are out there. This is Cloud 101 first day syllabus stuff, and will be a part of a series on cloud technologies that I have been working on researching and testing. So let’s get into it and if anyone has any questions please let me know.
What is “Cloud”?
- Public Cloud gets the IT budget burden of hardware and virtual platform licenses out of your organizations budget
- Can reduce the cost of Application delivery and overall OPEX
- Security this isn’t really a negative it is just like any other IT initiative if you properly plan your security and implement smart policies you can achieve a secure cloud environment
- CAPEX initial migration can seem like a large investment ROI needs to be examined and OPEX should be included in that analysis
- Change Management is needed more than in a private environment to ensure that your organization didn’t impact the SLA’s and to ensure that your provider is living up to their end of the agreement
- IT Department push back this is the biggest issue the fix is to help the IT team understand the goal and direction of the organization and how cloud plays into that
- CAPEX investments have already been made in most situations with fewer dollars a cloud vision can be realized
- Ownership the organization owns the hardware and software that is implemented in the cloud, this means that it can be depreciated and written off over time as well
- The other piece of ownership is that the organization has direct control over the assets and personnel who work in your environment this is the old adage of an enemy with-in can wreak more damage than an enemy at the gate. Knowing the staff in your IT environment is a valuable security measure.
- CAPEX & OPEX the organization is still paying for the IT personnel and resources as well as power and cooling for the data center
- Cost of application licenses that are sometimes included in public cloud offerings.
Hybrid Cloud: Is exactly what it sounds like, your organization maintains both a public and private cloud presence and there are applications in both locations. This allows for secure data to be maintained in the private cloud and public data to be provided in the public cloud. Data and Applications can easily maneuver between the two environments.
- Best of both worlds, managed environments with lower CAPEX
- Maneuverability and redundancy for critical environment applications
- Lower OPEXCAPEX for fail-over site than dual on-premises or dual public cloud solutions
- Cost essentially this boils down to having your cake and eating it too. Your organization has the costs of both on premises and a public cloud hosting site.
