To: Thomas Winston, Executive Manager From: Grant Kendall, Security Analyst Date: February 21, 2016 Re: Cloud Computing Benefits and Security Concerns Cloud Computing has the potential to save a lot of money for the company. Cloud Computing is defined by NIST as “a model for enabling ubiquitous, convenient, on demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.” (Mell, 2011) This means that instead of worrying about maintaining our own facilities we can pay monthly for a cloud service provider to do that for us. They will take care of all the …show more content…

Examples include Rackspace and, the most promising for our email, Amazon’s Web Services (AWS). Then beyond that there are a few different types of cloud these services can run on. Then there are three types of cloud. Public, Private and Hybrid. Public Clouds are for the general public and may be maintained by a business or government. (Mell, 2011) Not ideal for email or sensitive information. Private Clouds are provisioned for exclusive use. (Mell, 2011) Perfect for our email service. Hybrid clouds are defined by NIST as a mixture of the two above but Amazon has a hybrid deployment model that is slightly different and would help us to transition more easily. They define a Hybrid Cloud as a combination of existing non-cloud resources with the cloud. (Amazon) This is why I think that Amazon’s Web Services are the way to take our email to the cloud. We can slowly wean off our facilities while we are trying out the cloud and transitioning our employees. Then the cost reduction should be able to be measured and we can approximate it for the rest of our activities to see how much of a benefit it will be. The main benefit of moving email to the cloud will be reduced costs. Firstly maintenance will be cheaper for us since we don’t need to keep as many of our
