Common Challenges
Vendor Lock-in: Migrating between providers can be difficult and expensive due to proprietary services and APIs. Use open standards and containerization to reduce this risk.
Security Concerns: While providers handle physical security, you're responsible for data protection, access control, and compliance. The shared responsibility model defines these boundaries.
Cost Management: Cloud costs can spiral without monitoring. Without governance, teams may over-provision resources or forget to shut down unused instances.
Downtime Risk: Cloud providers experience outages. Designing for high availability across multiple regions and availability zones mitigates this.
Complexity: Managing hundreds of cloud services requires skilled teams. Start simple and add complexity as needed.
Making the Decision
Cloud computing is not always the right answer for everything. Evaluate your workloads: some legacy applications may not benefit from migration, and some regulatory requirements may demand on-premises hosting. The best approach is often a hybrid strategy that combines the best of both worlds.
