El almacenamiento en la nube es un componente crítico de la informática en la nube, que guarda la información que utilizan las aplicaciones. El análisis de big data, los almacenes de datos, el Internet de las cosas, las bases de datos y las aplicaciones de backup y archivado dependen de algún tipo de arquitectura de almacenamiento de datos. El almacenamiento en la nube, por lo general, es más fiable, escalable y seguro que los sistemas de almacenamiento en las instalaciones tradicionales.

2. Block vs File vs Object
Block Storage
Raw Storage
Data organized as an array of unrelated blocks
Host File System places data on disk
e.g.: Microsoft NTFS, Unix ZFS
File Storage
Unrelated data blocks managed by a file (serving) system
Native file system places data on disk
Object Storage
Stores Virtual containers that encapsulate the data, data attributes, metadata and Object IDs
API Access to data
Metadata Driven, Policy-based, etc

8. Elastic File System (EFS)

9. Amazon EFS is Simple
• Fully managed
- No hardware, network, file layer
- Create a scalable file system in seconds!
• Seamless integration with existing tools and apps
- NFS v4.1—widespread, open
- Standard file system access semantics
- Works with standard OS file system APIs
• Simple pricing = simple forecasting

10. Amazon EFS is Elastic
• File systems grow and shrink automatically as
you add and remove files
• No need to provision storage capacity or
performance
• You pay only for the storage space you use,
with no minimum fee
2

11. • File systems can grow to petabyte scale
• Throughput and IOPS scale
automatically as file systems grow
• Consistent low latencies regardless of
file system size
• Support for thousands of concurrent
NFS connections
Amazon EFS is Scalable
