Cloud Integration Cloud Providers and Cost Savings Analysis We have chosen to use Amazon Web Services as our cloud-based solution, specifically Amazon Elastic Compute Cloud (Amazon EC2). We will be using them to manage our online presence as far as marketing and will take advantage of their provided analytics services as well as their speed and provided infrastructure, but the main usage will be general office functions such as replacing our desktop clients with cloud based Virtual Machines, (VM) as well as replacing our storage servers with cloud-based servers. This will allow us to reduce costs by no longer having to replace obsolete hardware within employee workstations and allows scalability when it comes to server size. We don’t have to worry about adding hard drives or SSDs, if we need to expand, we can purchase more space on the cloud On Demand, within minutes ( Amazon EC2 ) . Amazon offers a free trial so we can test to see if we will reduce costs but estimates range in savings from 10% - 90%. 1.1 Cloud Service Provider Advantages One advantage of using Cloud Service will be accessibility and reliability. By moving our data and applications from our LAN to the cloud, our employees can access data not only from the office, but also when working remotely from home, or when travelling for business. When it comes to reliability, we don’t have to worry about a hardware failure in our equipment, or a power or internet outage in our region. Employees can still access services via mobile data if power and internet are out. The second advantage will be professional IT management. We

Cloud Integration won’t have to have a trained staff to install, configure and upgrade our equipment or to plan and design out network. Most of our IT needs, other than providing a VM client with a local internet connection, will be managed by the cloud provider. The third advantage will be speed and processing power. The speed and bandwidth capabilities that our cloud-based service can provide will well outperform anything we could afford to implement with hardware locally. Upgrades to the hardware to allow a competitive edge will also be managed by the provider and will not have to be our concern ( 12 benefits of cloud computing and its advantages ) . 1.2 Cloud Service Providers Disadvantages The first possible disadvantage of cloud service providers, according to (Larkin, 2020) is what is called “Vendor Lock-In”. Once we have began services with Amazon, in the future if we decide to switch to a different provider such as Azure or Google, it may not be easy to seamlessly transition without downtime or cost overlap when we end up paying for both services at the same time for a period. The second disadvantage could be downtime. If all of our data is stored and computing power is reliant on a cloud provider, if they have an outage our productivity comes to a standstill. In contrast, if we were using our own systems and not cloud, even if there was an internet outage, we could still get work done offline using our own equipment and local servers. The third disadvantage according to (Sharma, 2021) is the Lack of Support. If we are experiences difficulties or have questions, we may be forced to rely on web based FAQs or online chat support, instead of having a dedicated local IT professional who is familiar with exactly how our system is configured and the status of it.

Cloud Integration 1.3 Cloud Type The most suitable cloud type for our operation will be a Hybrid Cloud. A Private cloud would require us to deploy the infrastructure to create an intranet to connect our business, we do not have the budget nor the large-scale need for this, and since we are seeking the greater computing power available by an external cloud source, would be counterproductive. A Public cloud is a more appealing alternative to the Private cloud option but raises concerns about security and being able to meet compliance regulations from a clients when it comes to storing account specific or proprietary information on an external server. A community cloud is not relevant to our operation since we are relatively small and operate in a unique, niche market. With a Hybrid cloud solution, we can take advantage of cloud servers to store non-sensitive, commonly accessed files, but rely on our internal servers for account / customer specific data that needs to be protected while still taking advantage of the cloud processing power for Virtual Machines that our employees use to perform their daily work. (What's the difference between Public, Private, Hybrid, and Community Clouds? 2021)

Cloud Integration Section 2: Software as a Service (SaaS) Microsoft 365 for Business, with Microsoft Teams is the SaaS solution that will satisfy our requirements for general user productivity. With Microsoft 365, our users will have access to Outlook for email to communicate, as well as Word, Excel, and PowerPoint for all of their general administrative responsibilities. An extremely valuable tool included is Microsoft Teams, which allows chat, video calling, conference calls for meetings, as well as document sharing. This is important because it allows us to communicate and work as a team virtually. Microsoft Teams can link with Outlook so meeting invitations can be sent to entire groups to coordinate productivity, and shared documents can be viewed by the entire team at once in real time and can even be modified by multiple people at one time. Some additional benefits of using Microsoft 365 are that, since it is cloud based, our users can be productive from anywhere. Although there are desktop applications for each product, the users can log into their account and use browser-based versions of each of these tools and can access the shared files in either the Teams app or in a browser, allowing the user to never get caught without access to their files if they aren’t home. This also has the benefit of meaning we can free up storage space and processing power on each individual user’s workstation, as that heavy lifting can be performed by the cloud provider’s equipment. Some disadvantages of utilizing Microsoft 365 are that we are vulnerable to outages. There have been a few instances in the last couple years where the Microsoft Servers went down and significantly disrupted communication and operation. Some ways to mitigate this are to always have backups of our shared files stored on a physical location somewhere outside of
