Cloud Computing: Background You’ll Need 2

Describe the purpose of cloud computing
Cloud computing has become a part of every day life. Many iPhone users run out of space on their local devices, or choose to use a cloud backup service provided by Apple. Apple offers a cloud storage service called iCloud, which allows users to store photos, videos, documents, and other data securely online. Paying for Apple cloud storage involves a subscription-based model where users choose from several storage plans to fit their needs.

The purpose of cloud computing is to provide scalable and flexible resources for data storage, management, and processing over the internet, reducing the need for local servers and personal hardware. It enables businesses and individuals to access computing power, storage, and software applications from any device with an internet connection. This facilitates collaboration, enhances data accessibility, and allows for efficient resource utilization. Cloud computing also supports cost savings by reducing the need for physical infrastructure and maintenance, offering on-demand services that can be scaled according to current needs.

Before the advent of cloud computing, data storage primarily relied on physical hardware and local servers. Businesses and individuals stored their data on hard drives, external drives, and on-premises servers within their own facilities. These storage methods required significant investments in hardware, maintenance, and physical space. Additionally, data accessibility was limited to specific locations or devices, often requiring direct physical access to the storage medium. Backup processes were manual and prone to error, and scalability was a challenge, as expanding storage capacity often meant purchasing and integrating additional hardware. Data sharing and collaboration were also more cumbersome, frequently relying on physical transfer methods like USB drives or sending large email attachments.
