Technology Storage Flashcards
Storage Big Picture
Companies today need to collect, store, and analyze the data they´ve accumulated over the years on a massive scale. Storage devices in the cloud provide a place for companies to store data..
Amazon Simple Storage Service S3
It´s an object storage service for the cloud that is highly available
- Objects (or files) are stored in buckets ( or directories )
- Essentially unlimited storage that can hold millions of objects per bucket
- Objects can be public or private
- You can upload objects via the console, the CLI, or programmatically from within code using SDKs
S3 features
- You can set security at the bucket level or individual object level using access control lists ACLs, bucket policies, or access point policies.
- You can use S3 access logs to track the access to your buckets and objects
- You can enable versioning to create multiple versions of our file in order to protect against accidental deletion and to use a previous version.
- S3 is a regional service, but bucket names must be globally unique
Data Accessibility
1.- Durability
Is important so your objects are never lost or compromised.
Amazon S3 standard is designed for 99.999999999% (11 9´s) of durability
2.- Availability
Availability is important so you can access your dat quickly when you need it.
Amazon S3 Standard is designed for 99.99% avilability
S3 Storage Classes

S3 Standard
S3 Standard
- General Purpose storage
- Data stored across multiple AZs
- Low latency and high throughput
RECOMMENDED FOR
Frequent accessed data
Durability 11 - 9´s
Availability 4 - 9´s
S3 Intelligent Tiering
- Automatically moves your data to the most cost effective storage class
- Automatic cost savings
- No retrieval fees
- Data stores across multiple AZs
RECOMMENDED FOR
Data with unknown or changing access pattern
Durability 11 - 9´s
Availability 3 - 9´s
S3 Standard Infrequent Access (IA)
- Data accessed less frequenty but requieres rapid access
- Data stored across multiple AZs
- Cheaper than S3 Standard
RECOMMENDED FOR
- Long lived data
- Infrequently accessed
- Millisecond access when needed
Durability 11 - 9´s
Availability 3 - 9´s
S3 One Zone Infrequent Access (IA)
- Like S3 Standar IA but data stored in 1 AZ
- Cost 20% less than S3 Standard IA
- Data stored in this storage class can be lost
RECOMMENDED FOR
- Re creatable data
- Infrequently accessed with millisecond access
- Availability and durability not essential
Durability 11 - 9´s
Availability 99.5%
S3 Glacier
- Long term data storage and archival for lower costs
- Data retrieval takes longer
- 3 retrieval options 1-5 min, 3-5 hrs 5-12 hrs
- Data stored across multiple AZs
RECOMMENDED FOR
- Long term backups
- Cheaper storage options
S3 Glacier Deep Archive
- Like S3 Glacier but longer access times
- 2 retireval options 12hrs or 48 hrs
- Cheapest of all S3 options
- Data stored across multiple AZs
RECOMMENDED FOR
- Long term data archival accessed once or twice a year
- Retaining data for regulatory compliance requirements
S3 Outposts
- Provides object storage on premises
- A single storage class
- Store data across multiple devices and servers
RECOMMENDED FOR
- Data that needs to be kept local
- Demanding application performance needs
S3 in the Real World
Provide 2 use cases
- Static Websites . Deploy statis websites to S3 and use CloudFront for global distribution
- Data archive. Archive data using Amazon Glacier as a storage option for Amazon S3
- Analytics systems. Store data in Amazon S3 for use with Analytics services like Redshift and Athena
- Mobile apps. Mobile applicatoin users can upload files to an Amazon S3 bucket
EC2 Storage
- Instance Store
- Elastic Block Store (EBS)
- Elastic File System (EFS)
Amazon Elastic Block Store (EBS)
Storage device (called a volume) that can be attached to (or removed from ) your instance
- Data persist when the instance is not running
- Tied to one AZ
Can only be attached to one instance in the same AZ
RECOMMENDED FOR
Quick accesible data,Running a DB on an instance, Long term data storage
EC2 Instance Store
Is local storeage that is physically attached to the host computer and cannot be removed
Guess the service
Amazon Elastic File System (EFS)
Serverless network file system for sharing files
- Only supports the Linux file system
- More expensive than EBS
- Accessible across different AZs in the same Region
RECOMMENDED FOR
- Main directories for business critical apps
- Lift and shift existing enterprise apps
Storage Gateway
Is a hybrid storage service
- Connect on premises and cloud data
- Supports a hybrid model
RECOMMENDED FOR
- Moving backups to the cloud
- Reducing costs for hybrid cloud storage
- Low latency access to data
Instance Store
Dies with instance
Ephemeral
Temporary
