Understanding Cloud Migration Costs: Definitions and Key Stages

Cloud migration costs encompass the expenses involved in moving data from outdated legacy software to a cloud-based environment. This process is intricate and demanding.

Furthermore, numerous project-specific tasks and bottlenecks arise, making cost estimation challenging in the initial phases of migration. As a result, many businesses that recently migrated to the cloud cited cost estimation and budget adherence as their primary challenges. While migrating to the cloud can be costly, the expenses of not doing so often outweigh the investment. Let’s break down the costs.

Breaking Down Cloud Migration Costs Based on Milestones

Before embarking on a cloud data migration project or developing a cloud-based architecture from scratch, it’s crucial to consider all potential pitfalls, devise a data migration strategy, and anticipate associated risks. Utilize our dedicated guide as a starting point.

Cloud migration costs can be divided into several milestones:

• Pre-Migration

This initial phase involves identifying the reasons for transitioning to the cloud, identifying core pain points, assessing the data volume for transfer, and selecting a preferred cloud provider. These preliminary steps provide a broad overview of expected costs, including:

• On-premise data management expenses, covering aspects like new storage, infrastructure operations, server capabilities, expert compensation, software licenses, maintenance, warranties, and tech support.
• Database upgrades to ensure compatibility with the new system, which may require software updates and consultations with migration vendors.
• Testing cloud solutions through rented demo environments and possible Proof of Concept initiatives.
• Migration

This phase consumes significant time and resources as data must be classified according to platform requirements and securely transferred. Costs during this phase include:

• Migration fees are charged by the cloud vendor and labor costs for data migration companies if a third-party team is involved.
• Application and code modifications, infrastructure development, and system setup as per business requirements.
• Refactoring to ensure application and data compatibility with the new system.
• Post-Migration

Post-migration activities focus on supporting the cloud infrastructure effectively, including:

• Licensing or support costs for maintaining infrastructure and related software.
• System operations, administration, monitoring, updates, and staff training on the new system.
• These costs can be categorized as direct (related to the migration process) and indirect (mediated expenses).

Factors Influencing Cloud Migration Costs

The final cost of cloud migration depends on various factors:

• Project scale: Larger projects generally incur higher costs due to increased workload and planning efforts.
• Challenges and specifics: Overcoming challenges such as legacy system maintenance and third-party support impacts overall costs.
• Choice of cloud services: Different cloud providers offer diverse pricing plans and services, affecting migration costs.

Approaches to Estimating Cloud Migration Costs

Three main approaches help estimate cloud migration expenses:

• Analogy Approach: Utilizes past migration projects’ logic and milestones, often in collaboration with experienced migration vendors.
• Expert Judgement Approach: Relies on the knowledge and expertise of development teams or consultants.
• Algorithmic Model Approach: Involves creating formulas to relate dependent and independent variables, suitable for rough estimates.

4 Steps to Calculate Cloud Migration Costs

• Assess current IT infrastructure costs and identify cost reduction metrics.
• Use cloud migration cost calculators provided by leading cloud providers to estimate usage costs.
• Collaborate with a migration vendor for precise cost estimations and guidance on choosing a cloud provider.
• Allocate post-migration and additional risk-related costs for a comprehensive budget.

4 Tips for Cost-Effective Cloud Migration

While cost factors vary, consider these tips for cost savings:

• Define data migration scope to focus on critical data first.
• Select the right migration strategy based on technical needs.
• Opt for effective pricing models and consider reserved instances for predictable workloads.
• Partner with experienced migration vendors to avoid costly mistakes and ensure data safety.
