What Is Cloud Computing?
Cloud computing is the delivery of computing services — servers, storage, databases, networking, software — over the internet instead of using your own physical hardware. Instead of buying a server for $50,000, you rent computing power from Amazon AWS, Microsoft Azure, or Google GCP. You pay for what you use and scale as you grow.
Why It Matters for African Businesses
- No upfront hardware costs — start for $5 per month instead of $50,000 in servers
- Global scale from day one — deploy in multiple regions without building data centres
- Professional infrastructure — same security and reliability as the world's largest companies
- Pay as you grow — costs scale with your business, no expensive overprovisioning
Cloud Certifications and Their Value
- AWS Certified Cloud Practitioner — beginner-level, excellent starting point
- AWS Solutions Architect Associate — mid-level, highly valued by employers globally
- Azure Fundamentals AZ-900 — beginner-level Microsoft Azure certification
- Google Associate Cloud Engineer — mid-level GCP certification
Cloud-certified professionals in Africa earn significantly above-average salaries. AWS Solutions Architects can command ₦10–25 million annually in Nigeria, with remote roles paying far more.
