- Downtime and Hidden Costs: Consider losses from outages or slow performance. It includes lost revenue, staff time, customer dissatisfaction, and damage to brand trust.
Step 2: Evaluate What You’ll Spend on the Cloud
Before you move to the cloud, it is important to know all the potential costs. Here’s how to break down and estimate your cloud migration cost and monthly cloud spending accurately.
1. Migration costs
When moving to the cloud, you must consider technical changes and associated costs. There are several ways to migrate applications and data, each with different cost implications.
| Rehosting (Lift and Shift): | This method moves applications to the cloud without changing the code. It's faster but may not fully utilize cloud capabilities.
|
| Refactoring | Modify parts of the code to use cloud features like auto-scaling and load balancing. It improves performance but requires moderate changes.
|
| Revising | Extend or adjust the application’s code to add new capabilities, often to meet changing business needs.
|
| Rebuilding | Redesign and rewrite the app from scratch to fully optimize for cloud technologies like containers or serverless computing.
|
| Replacing
| Use third-party SaaS (Software as a Service) solutions instead of your current applications.
|
Each migration method offers a different balance between speed, complexity, and cost.
Other Factors That Affect Migration Costs:
1. Business and Technical Needs
Start by defining the value you expect from the migration. Are you aiming for lower costs, better scalability, or faster innovation? This clarity helps shape the scope of migration and the Return on Investment (ROI), which you’ll calculate later.
2. Choosing the Right Cloud Environment
Public Cloud: Shared resources hosted by cloud providers, cost-effective and scalable.
Private Cloud: Dedicated resources, usually chosen for sensitive data or compliance needs.
Hybrid Cloud: Combining public and private clouds offers the right balance of flexibility, speed, and control.
3. Consultation and Support Costs
If your team lacks cloud expertise, hiring external consultants is common. These consultants can help you with:
Cloud migration planning and assessment
Architecture and environment design
Security configuration
Cloud provider selection
Team training and ongoing support
Fees depend on project complexity, duration, and the kind of support needed.
4. Internal Employee Involvement
Internal teams will also contribute time and effort. It adds to the migration cost, which includes:
Training & Certification: Upskilling on cloud technologies, DevOps, or SRE
Overtime Costs: Teams working outside regular hours
Hiring Cloud Talent: Acquiring niche cloud roles (e.g., cloud architects, security engineers)
5. Network Bandwidth
Cloud apps depend on reliable internet access. Insufficient bandwidth leads to lag, poor performance, and downtime. Also, transferring data to the cloud can incur networking fees, especially for large data volumes.
2. Monthly Cloud Costs
After migration, cloud costs shift to a pay-as-you-go model. Yet, to avoid unexpected bills, it’s important to estimate your monthly expenses by considering:
Types of Cloud Services Used
- Compute Services: These power your applications. Its costs depend on the type of virtual machines (VMs), memory, CPUs, or serverless functions used.
- Storage Services: These keep your data. Charges vary based on storage type (e.g., file, block, object), volume, and how often you access data.
- Network Services: These handle data flow and connectivity. Its costs depend on the data transfer volume, load balancer usage, and data travel distance.

- Reserved Instances/Savings Plans: Commit to a specific usage level for a lower price.
- Hybrid Approach: Combine on-demand and reserved usage for cost efficiency and flexibility.
Use pricing calculators (e.g., AWS Pricing Calculator) to estimate your costs based on selected services, workloads, and regions.
Understanding Your Workloads and Usage
Cloud billing is driven by how you use your resources. To make accurate estimates, analyze:
- Applications in Use: List all business-critical apps you plan to migrate.
- Dependencies: Understand which operating systems, databases, or tools your apps rely on.
- Resource Requirements: Check current usage of CPU, memory, storage, and bandwidth.
- Usage Patterns: Identify peak usage hours, off-hours, and seasonal spikes to plan capacity efficiently.
- Workload Types: Classify your workloads based on complexity and migration readiness. For example, ERP systems may need high-performance instances, while internal tools might run on lighter setups.
Step 3: Calculate the Existing System’s Intangible Costs
On-premises computing involves many hidden or intangible costs that should be considered when calculating cloud TCO (Total Cost of Ownership). These include:
1. Downtime
A failure in on-premises systems halts operations, making downtime one of the most overlooked yet costly factors. To accurately assess its cost:
Review server logs to identify the average frequency and duration of system interruptions.
Multiply the average downtime by the hourly wage of affected employees to determine lost productivity.
To estimate revenue loss, multiply the number of downtime hours by your average hourly revenue.
Don’t forget to include any expenses incurred for maintenance or repairs required to restore system functionality.
2. Slow Speeds
When systems run slowly, they cause delays and reduce how much work gets done. It leads to hidden costs that are ignored. To calculate the cost of slow speeds:
Identify Affected Employees
Start by determining how many employees were impacted by the system slowdown.
Formula: Number of Affected Employees × Hourly Wage = Initial Productivity Cost
Estimate the Drop in Productivity
Estimate how much productivity was lost due to the slowdown. For example, if performance falls from 90% to 50%, calculate the loss percentage:
Formula: [(New Productivity – Original Productivity) ÷ Original Productivity] × 100 = Productivity Loss %
In this case:
[(50 – 90) ÷ 90] × 100 = -44.4% drop in productivity
Calculate the Lost Productivity Cost
Multiply the base productivity cost by the loss percentage and the number of hours affected.
Formula: Base Productivity Cost × (Productivity Loss % ÷ 100) × Hours Affected = Lost Productivity Cost
Add System Support Costs
Add any costs related to IT support or system maintenance during the slowdown.
Estimate Customer Impact
If customers were impacted, estimate the number affected and calculate the potential revenue loss.
Formula: Impacted Customers × Avg Revenue per Customer = Estimated Customer Loss
Note: Add all the above values to find the total cost of slow system performance.
3. Opportunity Costs
Opportunity Costs
Every decision comes with missed opportunities. Companies choosing an on-premises solution may miss out on valuable cloud benefits. These opportunity costs include:
Compliance Risks
On-premises systems require manual effort to manage encryption, backups, and audits, increasing the risk of error and non-compliance.
What you miss with the cloud is automated compliance tools, built-in security features, and globally recognized certifications that simplify and strengthen data protection.
Capital Expenditures (CapEx)
On-premises infrastructure demands heavy upfront investment in servers, storage, and licenses, tying up funds in depreciating assets.
What you miss with the cloud is a usage-based pricing model that reduces capital strain and frees the budget for strategic, growth-focused initiatives.
Increased Agility
Scaling on-premises systems takes weeks due to hardware procurement and setup delays, limiting your ability to respond to fast-changing demands.
What you miss with the cloud is instant provisioning, real-time scalability, and the flexibility to pivot quickly without infrastructure bottlenecks.
Wasted Employee Time
IT teams managing on-premises environments spend valuable hours on patching, monitoring, and firefighting issues instead of innovating.
What you miss with the cloud is automated operations and managed services that allow your teams to focus on business-critical and future-ready projects.
