Problem Analysis:

The task involves analyzing a scenario where a company is considering using cloud computing services to reduce costs. The goal is to evaluate the feasibility and implications of this decision based on the provided information.

#### Key Points from the Scenario:
1. Current Setup:
- The company has 50 servers.
- Each server costs $2,000 per year for maintenance.
- Total annual maintenance cost: \( 50 \times \$2,000 = \$100,000 \).

2. Cloud Computing Option:
- Cloud provider charges $1,800 per year per server.
- Additional setup cost: $10,000 (one-time).
- Migration cost: $5,000 (one-time).

3. Questions to Answer:
- Which option is more cost-effective over a 5-year period?
- What are the advantages and disadvantages of each option?
- Should the company migrate to the cloud? Why or why not?

Solution:

#### Step 1: Calculate Total Costs Over 5 Years

##### Current Setup (On-Premises):
- Annual maintenance cost per server: $2,000.
- Number of servers: 50.
- Total annual maintenance cost: \( 50 \times \$2,000 = \$100,000 \).
- Total cost over 5 years: \( 5 \times \$100,000 = \$500,000 \).

##### Cloud Computing:
- Annual cost per server in the cloud: $1,800.
- Number of servers: 50.
- Total annual cost in the cloud: \( 50 \times \$1,800 = \$90,000 \).
- Total cost over 5 years (excluding one-time costs): \( 5 \times \$90,000 = \$450,000 \).
- One-time setup cost: $10,000.
- One-time migration cost: $5,000.
- Total one-time costs: \( \$10,000 + \$5,000 = \$15,000 \).
- Total cost over 5 years (including one-time costs): \( \$450,000 + \$15,000 = \$465,000 \).

---

#### Step 2: Compare Costs
- On-Premises: \$500,000 over 5 years.
- Cloud Computing: \$465,000 over 5 years.

The cloud computing option is cheaper by \( \$500,000 - \$465,000 = \$35,000 \) over 5 years.

#### Step 3: Advantages and Disadvantages

##### On-Premises (Current Setup):
- Advantages:
1. Control: The company has full control over its infrastructure.
2. Customization: Can tailor the environment to specific needs.
3. Data Security: Data is stored locally, which may be preferred for sensitive information.
- Disadvantages:
1. High Maintenance Costs: Significant ongoing expenses for server maintenance.
2. Scalability Limitations: Difficult to scale up or down quickly.
3. Infrastructure Management: Requires dedicated IT staff for management.

##### Cloud Computing:
- Advantages:
1. Cost Savings: Lower total cost over time due to reduced maintenance expenses.
2. Scalability: Easy to scale resources up or down as needed.
3. Reliability: Cloud providers often offer high availability and redundancy.
4. Automation: Many cloud services include automated updates and management tools.
- Disadvantages:
1. Initial Costs: High one-time setup and migration costs.
2. Security Concerns: Potential risks related to data privacy and security in a shared environment.
3. Dependency: Reliance on the cloud provider's services and internet connectivity.

#### Step 4: Decision-Making
- Financial Perspective: The cloud computing option is more cost-effective over a 5-year period, saving the company \$35,000.
- Operational Perspective: The cloud offers scalability and automation benefits, which can improve efficiency.
- Risk Perspective: While there are initial costs and potential security concerns, these can be mitigated with proper planning and security measures.

---

Final Recommendation:

The company should migrate to the cloud. The cost savings over 5 years (\$35,000) justify the one-time setup and migration costs. Additionally, the cloud provides scalability, reliability, and automation benefits that can enhance operational efficiency.

---

Final Answer:

\[
\boxed{\text{The company should migrate to the cloud.}}
\]
