What is Cloud Computing?

Cloud computing means renting computing resources from a provider instead of buying and maintaining your own servers. The three major providers are Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure. Together they hold over 65% of the global cloud infrastructure market.

Why Cloud Computing Matters for Apps

Before cloud computing, launching an app required purchasing physical servers, estimating traffic in advance, and paying for capacity you might never use. Cloud computing changed this by offering three key benefits.

Scalability. Resources scale up or down automatically based on demand. If your app goes viral overnight, the cloud handles the spike without downtime.

Cost efficiency. You pay only for what you use. A startup can run its backend for under $50 per month, while an enterprise app might spend $10,000 per month during peak traffic and less during quiet periods.

Global reach. Cloud providers operate data centers worldwide. You can deploy your app closer to users in any region, reducing latency and improving performance.

Cloud Service Models

IaaS (Infrastructure as a Service) provides virtual servers, storage, and networking. You manage the operating system and software. Examples: AWS EC2, Google Compute Engine.

PaaS (Platform as a Service) provides a managed environment for deploying applications without managing servers. Examples: Google App Engine, Heroku, AWS Elastic Beanstalk.

SaaS (Software as a Service) provides ready-to-use software over the internet. Examples: Slack, Salesforce, Google Workspace. See our SaaS glossary entry for more detail.
