Cloud Storage: Storing Data in the Cloud
Learn about cloud storage services and how to store data in the cloud.
What you'll learn
- Identify and describe at least three different cloud storage service providers (e.g., Google Drive, Dropbox, OneDrive) and their key features with 100% accuracy.
- Explain the advantages and disadvantages of using cloud storage compared to local storage, citing at least two advantages and two disadvantages in a written paragraph.
- Apply cloud storage principles by successfully uploading, organizing, and sharing a file using a chosen cloud storage service (e.g., Google Drive) demonstrating the ability to control access permissions (e.g., view only, edit).
- Evaluate the security and privacy considerations associated with storing data in the cloud, identifying at least three potential risks and suggesting mitigation strategies in a short essay.

Key Concepts & Vocabulary
TermDefinitionExample
Object StorageA data storage architecture that manages data as objects, as opposed to a file hierarchy or blocks. Each object typically includes the data itself, a variable amount of metadata, and a globally unique identifier (key).Amazon S3 or Google Cloud Storage. When you upload a photo to a social media site, it's stored as an object. The photo is the data, the metadata might include the date, location, and camera type, and it's retrieved using a unique URL (its key).
Block StorageA technology used to store data files on Storage Area Networks (SANs) or cloud-based storage environments. It breaks data into fixed-size blocks, each with its own unique address, but with no additional metadata. It behaves like a raw hard drive for a server.Amazon EBS (Elasti...

Core Syntax & Patterns
The CAP Theorem
A distributed data store can only provide two of the following three guarantees: Consistency, Availability, and Partition Tolerance (CAP).
Since network partitions (failures) are a given in distributed systems, cloud storage systems must choose between Consistency (every read receives the most recent write or an error) and Availability (every request receives a non-error response, without guarantee that it's the most recent write). This is a fundamental trade-off in system design. For example, a system might choose to be 'Eventually Consistent' to maximize availability.
Storage Tiering Pattern
Data is categorized and moved between high-cost, high-performance storage and low-cost, low-performance storage tiers based on its access frequency and per...
