Storage Technology and Services Flashcards
What does EC2 stand for?
Elastic Compute Cloud
What is EBS?
Elastic Block Store
It’s directly connected to your EC2.
- data stays intact even when ec2 instance is stopped
- Highly Available and Durable
- Scalable
What is the Use Case of Elastic Block Store (EBS)?
Hosting Relational or NoSQL Databases
Data warehousing
ERP and CRM applications
What is EFS?
Elastic File System
It’s a scalable file storage systems for ec2 (and other service)
What is the use case of Elastic File System (EFS)?
- Content management
- Data analytics applications
- Development and testing environments
What are EC2 instance stores?
Temporary storage
- High I/O Performance
- Temporary Storage
- No extra cost, it’s included with the EC2 instance
When to use EC2 instance stores?
- Temporary storage (cache and buffers)
- Write and discard large amounts of data
- Storage between multipleEC2 instances
What is S3 and what does it stand for?
S3 stands for Simple Storage Service
it’s a Scalable, secure, and versatile storage solution
What 3 things a stored in a S3 bucket?
1) A key
2) (the real) data
3) meta-data
S3 - Standard Storage Class
Retrieval times, fee differences, one or multiple AZ’s?
- Frequently used data (fast retrieval time/ low latency)
- ## Multiple AZ’s
S3 - Intelligent tiering Class
Retrieval times, fee differences, one or multiple AZ’s?
- Data with unpredictable excess patterns
- Moves it between different S3 classes
- Fee can save money
S3 - Standard-Infrequent Access Class
Retrieval times, fee differences, one or multiple AZ’s?
user for data less frequently need, but when needed rapid access is required.
- Number of AZ’s:
- Pricing:
S3 - One Zone-infrequent Access Class
Retrieval times, fee differences, one or multiple AZ’s?
- used for data that isn’t to important or is easy reproducible (like a thumbnail)
- Sores data in 1 AZ
- It’s cost effective
S3 - Glacier Instant Retrieval Class
Retrieval times, fee differences, one or multiple AZ’s?
- used for archive storage
- Quick retrieval
- Lowest cost for long time storage
S3 - Glacier Flexible Retrieval Class
Retrieval times, fee differences, one or multiple AZ’s?
- Used for archive storage that’s excessed 1-2 times a year
- ‘slow’ retrieval
-
S3 - Glacier deep archive Class
Retrieval times, fee differences, one or multiple AZ’s?
- Archive storage for data you nearly don’t need
- cheapest storage for long term data
- retrieval is slow(!) can take up to 12 hours/
Used to save datasets that need to be saved for regulations. For example health care or tax.
What are the rules for Bucket naming?
the bucket name has to be globally unique
What are Bucket permissions?
The bucket policy contains permission for any user (real users and for example EC2 instances) to access the bucket
What is Bucket versioning?
Recover easily previous bucket versioning.
What is FSx?
is a storage shelf to support specific Windows Windows Workloads?
Fully Managed Windows File System
Build on windows servers
What is Elastic Disaster Recovery?
It’s a backup service to make sure:
- Business continuity
- Protects you from data disruptions
- and it’s flexible and adaptable
What are the 2 EBS Volume types?
- SSD (faster, more expensive, quick operations
- HHD (slower, cost efficient, throughput tasks)
What are snapshots?
- is an incremental Backup
- via this way you can quicky restore and launch a volume
- snapshots can be selled to other AWS accounts
- Cost-effective
What is AWS Storage Gateway?
is a hybrid Storage service. That bring local data to the AWS cloud
Benefits of the AWS Storage Gateway
- No need to store data yourself on premise
- Cost effective
- Secure, data is encrypted
- Seamless integration with existing applications
name 4 types of Storage Gateways
-S3 file gateway
- Volume Gateay
- Tape gateway
- FSx File Gateway
What is AWS Backup?
AWS backup created automated and centralized data protection
It integrates with various AWS services.
It backs up:
EC2, Elastic Block Store Volumes. RDS, DynamoDB tables, Elastic file system, FSx file systm, storage gateway volumes
What are the Core features AWS Backup
- Centralized Backup management
- Automated Backup Scheduling
- Encryption & compliance
- Cross-region and account backup.
