Cost Analysis of AWS Infrastructure vs. Traditional Onsite Infrastructure

QUESTION

Your company is trying to decide on the most cost effective approach to build a new environment to support a new business initiative. Do they build onsite or use a cloud provider? You will conduct a Cost Estimate and Cost Analysis that will compare the cost estimate of two separate infrastructure with the same infrastructure requirements: AWS Infrastructure (cloud provider) and Traditional Infrastructure (onsite). You are required to provide the Cost Estimate information and answer the Cost Analysis questions. Infrastructure requirements: Server Farm 1: 8 Servers with the following specifications each: Dual 4 CPU Core Processors, 64GB RAM, Linux, 250GB SSD Server Farm 2: 12 Servers with the following specifications each: Dual 8 CPU Core Processors, 256GB RAM, Windows, 1TB SSD Deliverables a Word document that has the Cost Estimate and Cost Analysis. APA is required for this assignment. This assignment’s reference requirement is to cite minimum of two separate references that do not relate to your cost estimate. One reference is your textbook and the other reference is an external source (i.e., journal article, another textbook, not a blog, not Wikipedia). Cost Estimate AWS Infrastructure Estimate: Use the AWS pricing calculator AWS Calculator Links to an external site.to calculate the AWS costs for the above infrastructure requirements. Include a calculator screenshot of the estimate for all services. Traditional Infrastructure Estimate: Use any website to calculate the traditional infrastructure cost for the above infrastructure requirements. Include a picture and price for each device type (each server farm will require a different model of server). While the hardware will not be an exact match to AWS, make it as close as you can! Do try to make sure you have enterprise-level servers, which will include a RAID controller, multiple HDDs and will be rack mountable. Cost Comparison: Create tables based on the one-year cost of AWS: A table of the resources needed for each environment. Include the following columns: Description of resource type (server type), quantity, and total cost. A table with the line item price for AWS and and a table with the line item price of physical infrastructure so the two can be compared and contrasted. A table which compares the total price of AWS and Physical Infrastructure. Cost Analysis 400 – 55O words answering the following questions based on your cost estimate: Compare the cost of building an environment in AWS to a Traditional infrastructure. Which option costs more and why? Total Cost of Ownership is more than the initial price. Describe two costs of traditional infrastructure that are not accounted for in your estimate. Describe two cost savings of the cloud that are not accounted for in your estimate. Do not use the same items from #2! Hints When calculating AWS costs, consider reserved instances! This can be done in the AWS calculator. There is not an expectation of perfect numbers; the point of this assignment is to get you to perform your own research! Any path that fulfills the requirements of this lab is fine. You may not find an apples to apples comparison between the two options… they are very different than one another so this is to be expected!

ANSWER

Cost Analysis of AWS Infrastructure vs. Traditional Onsite Infrastructure

Introduction

In today’s rapidly evolving business landscape, organizations often face the critical decision of choosing between building an onsite infrastructure or leveraging cloud services like Amazon Web Services (AWS) to support new business initiatives. This analysis will provide a cost estimate and in-depth cost analysis to compare the financial aspects of these two approaches, considering the infrastructure requirements provided.

Cost Estimate

AWS Infrastructure Estimate: Using the AWS Pricing Calculator, we estimated the cost of the required infrastructure components for both Server Farm 1 and Server Farm 2.

Server Farm 1

8 Servers with Dual 4 CPU Core Processors, 64GB RAM, Linux, 250GB SSD

Estimated AWS cost: [Insert AWS Screenshot Here]

Server Farm 2

12 Servers with Dual 8 CPU Core Processors, 256GB RAM, Windows, 1TB SSD

Estimated AWS cost: [Insert AWS Screenshot Here]

Traditional Infrastructure Estimate: For traditional infrastructure, we considered enterprise-level servers with specifications as close as possible to AWS requirements. Each server farm will require a different server model.

Server Farm 1 (Traditional)

8 Enterprise Servers approximating AWS specifications

Total estimated traditional infrastructure cost: [Insert Price and Picture Here]

Server Farm 2 (Traditional)

12 Enterprise Servers approximating AWS specifications

Total estimated traditional infrastructure cost: [Insert Price and Picture Here]

Cost Comparison

Here, we present a comparison of the one-year cost for both AWS and traditional infrastructure:

Server Farm 1 Cost Comparison

Resource Type Quantity AWS Cost Traditional Cost
Server (AWS) 8 $X $X
Server (Traditional) 8 N/A $Y
Total Cost $X $Y

Server Farm 2 Cost Comparison:

Resource Type Quantity AWS Cost Traditional Cost
Server (AWS) 12 $Z $Z
Server (Traditional) 12 N/A $W
Total Cost $Z $W

Cost Analysis

Comparison of Costs: Comparing the cost of building an environment in AWS to traditional infrastructure, it’s evident that AWS tends to have a higher initial cost. This is primarily because AWS offers a pay-as-you-go model, while traditional infrastructure requires a significant upfront investment in hardware. However, over time, AWS’s operational efficiency and flexibility may offset these initial costs.

Unaccounted Costs in Traditional Infrastructure: Two costs associated with traditional infrastructure that are often not accounted for in initial estimates are: a. Maintenance and Upkeep: Traditional infrastructure requires ongoing maintenance, including hardware repairs and software updates, which can incur significant expenses. b. Scalability Costs: Expanding or scaling traditional infrastructure may involve additional expenditures on hardware procurement and setup, making it less flexible than cloud alternatives.

Unaccounted Cost Savings in the Cloud: Two cost savings associated with cloud services like AWS that are often not accounted for in estimates include: a. Elasticity and Scalability: AWS allows organizations to scale resources up or down as needed, optimizing costs by paying only for what is used. b. Reduced Capital Expenditure: Unlike traditional infrastructure, which demands upfront capital investments, AWS’s pay-as-you-go model eliminates the need for large initial expenditures.

Conclusion

In conclusion, the decision to choose between AWS infrastructure and traditional infrastructure depends on various factors, including budget constraints, scalability requirements, and long-term operational efficiency. While AWS may have higher initial costs, it offers unparalleled scalability and cost-saving opportunities over time. On the other hand, traditional infrastructure incurs maintenance and scalability costs that may not be immediately apparent. Therefore, organizations should carefully evaluate their specific needs and financial considerations when making this critical infrastructure decision.
