Cloud Computing

Technology that makes use of the remote service over the internet to manage, access and store data online instead of local drives is known as cloud computing. Instead of maintaining physical servers’ data centers, users can use technology services. The data includes files, documents, images, video, audio, etc. However, the cloud refers to the internet or network.

**Cooling Technology in Data Centers: Environmental Impact and Challenges**

Many data centers that support cloud computing now pipe chilled water through the server racks to cool the facility rather than air. This represents an attempt to reduce carbon footprint. However, this shift has introduced several challenges that need to be addressed.

### Key Points:

- **Chilled Water Systems**: Utilized as a more energy-efficient alternative to traditional air cooling methods for reducing data center temperatures.

- **Carbon Footprint Reduction**: By using water, data centers can decrease reliance on energy-consuming air conditioning units, contributing to lower emissions.

### Challenges:

- **Water Consumption**: The increased use of water poses sustainability concerns, particularly in regions facing water scarcity.

- **Infrastructure Costs**: Retrofitting existing facilities or building new ones to accommodate water cooling systems can entail significant expenses.

- **Leak and Damage Risks**: The introduction of water near electronic equipment increases the potential for leaks, which could lead to hardware damage and data loss.
