Cloud and Local Storage

4. Cloud Storage

Cloud storage involves saving digital data on remote servers located in offsite commercial data centres (managed by cloud providers like Google Cloud, AWS, or Microsoft Azure), accessed over the internet.

Advantages:

• Universal Accessibility: Access files from any device with an internet connection anywhere in the world.
• Automated Backup & Redundancy: Data is mirrored across multiple physical data centres, protecting against local fire, theft, or hardware failure.
• Elastic Scalability: Storage capacity can be increased instantly on demand without purchasing physical hardware.

Disadvantages:

• Requires Network Access: Cannot access or download files if internet connection is down or slow.
• Security & Privacy Risks: Data is stored on third-party infrastructure and vulnerable to interception or unauthorized access if account credentials are breached.
• Ongoing Subscription Costs: Incurs recurring monthly or annual subscription fees over time.

Worked decision and independent comparison

A travelling designer needs files on two devices. Cloud storage supports access and sharing, but upload bandwidth, account security, ongoing fees and provider availability matter. Keep a suitable backup/version history: synchronisation can also synchronise an accidental deletion.

A field team works where connectivity is unreliable. Compare local storage plus planned backups with a cloud-only workflow. State which need determines your choice and one risk that remains.
