Cloud Computing Explained: What It Is & How It Works
Introduction
Cloud computing is one of the biggest changes in modern IT. Instead of buying and maintaining servers, businesses rent computing power and software online. This shift reduces costs, speeds up operations, and makes scaling easy. The rise of cloud computing is also enabling the rapid adoption of artificial intelligence technologies, which are transforming industries like healthcare, finance, and education by making advanced computing power more accessible to businesses of all sizes.
For over 20 years, L4RG has helped 100,000+ global clients move to the cloud. We've seen how cloud adoption drives growth, and we understand the challenges companies face.
What Is Cloud Computing?
Cloud computing means delivering IT services—like storage, servers, software, and databases—over the internet. You pay for what you use, just like electricity or water.
Key benefits include:
- No need to buy expensive hardware.
- Quick setup and easy upgrades.
- Access anytime, anywhere.
- Pay only for the resources you use.
Core Principles of Cloud Computing
Cloud technology follows a few simple principles:
- On-demand access – Start or stop services whenever you need.
- Broad access – Connect from laptops, mobiles, or tablets.
- Resource pooling – Shared infrastructure serves multiple users.
- Elastic scaling – Add or reduce resources in minutes.
- Measured service – Track usage and pay only for what you consume.
Cloud Service Models
There are three main service models.
1. IaaS (Infrastructure as a Service)
- Rent servers, storage, and networks.
- Best for businesses that want flexibility without hardware costs.
2. PaaS (Platform as a Service)
- Provides tools for building and testing apps.
- Developers save time and focus on coding, not infrastructure.
3. SaaS (Software as a Service)
- Use ready-made applications like email, CRM, or ERP.
- Access via web browsers with no installation.
Cloud Deployment Models
Different businesses need different setups.
- Public Cloud – Shared by many users, cost-effective.
- Private Cloud – Exclusive to one company, more secure.
- Hybrid Cloud – Mix of both, flexible and balanced.
Benefits of Cloud Adoption
Moving to the cloud gives companies many advantages:
- Lower costs – No upfront hardware.
- Scalability – Add resources as your business grows.
- Reliability – High uptime and quick disaster recovery.
- Security – Built-in protection and regular updates with cyber security support.
- Productivity – Teams work from anywhere with remote support services.
Cloud Migration Strategies
Adopting cloud takes planning. Here are common approaches:
1. Lift and Shift – Move apps to the cloud with minimal changes.
2. Re-platform – Make small adjustments for better performance.
3. Re-architect – Redesign apps to use full cloud features.
Challenges to Consider
Cloud is powerful, but not without risks.
- Data security – Must follow strict protection policies with data protection support.
- Compliance – Some industries need extra safeguards.
- Costs – Poor planning can cause overspending.
- Downtime – Internet outages may affect access.
With expert tech support planning, these risks can be reduced.
