What are the key differences between cloud and on-premises infrastructure?

Cloud infrastructure offers scalability and lower upfront costs, while on-premises provides complete control and data sovereignty but requires higher capital investment.

Choosing between cloud and on-premises infrastructure involves evaluating multiple factors including cost, control, scalability, and compliance requirements.

Cost Structure:

• Cloud: Operational expense (OpEx) model with pay-as-you-use pricing. Lower upfront costs but potentially higher long-term expenses for consistent workloads.
• On-premises: High capital expense (CapEx) with equipment purchases, but lower ongoing operational costs for predictable workloads.

Scalability:

• Cloud: Instant scalability up or down based on demand. Perfect for variable workloads and rapid growth.
• On-premises: Limited by physical hardware capacity. Scaling requires planning and capital investment.

Control and Customization:

• Cloud: Limited control over underlying infrastructure. Standardized configurations may not meet all requirements.
• On-premises: Complete control over hardware, software, and configurations. Custom solutions possible.

Security and Compliance:

• Cloud: Shared responsibility model. Provider handles infrastructure security, customer handles application security.
• On-premises: Full responsibility for security but complete control over data location and access.

Maintenance:

• Cloud: Provider handles hardware maintenance, updates, and replacements.
• On-premises: Organization responsible for all maintenance, updates, and lifecycle management.

Many organizations adopt hybrid approaches to leverage benefits of both models. Baptiste Ghesquiere from BaNaNi recommends evaluating specific business needs rather than following trends.
