AWS Storage Services

AWS facilitates movement from DCs to Cloud because of

• security
• flexibility
• cost efficiency
• scalability which means it needs to provide
• Compute
• Storage
• Database
• Network and AWS does this very well. This course focuses on Storage

Why so many storage services? For the same reason why there are so many on-premise storage options:

• Storage Areas Network (SAN)
• Network Attached Storage (NAS)
• Directly Attached Storage (DAS)
• Tape Backup

which is that different benefits and features are provided by different options:

• Cost variants
• Storage capacity
• Security features
• Varied levels of durability
• Varied levels of Availability
• Read/write speed
• Accessibility
• Media Type
• Auditable and traceable
• backup and file storage

Data storage categorization

1. Block
   1. Data is stored in chunks known as blocks
   2. Blocks are stored on a volume and attached to a single instance
   3. Provide very low latency data access
   4. Comparable to DAS storage used on premises
2. File
   1. Data is stored as separate files with a series of directories forming a data structure hierarchy
   2. Data is stored within a file system
   3. Shared access is provided for multiple users
   4. Comparable to NAS storage used on premises
3. Object
   1. Each object does not conform to a data structure hierarchy. Objects are stored across a flat address space
   2. Objects are referenced by a unique key
   3. Each object can also have associated metadata to help categorize and identify the object.
