Q

S3 Objects

A

• Objects (files) have a Key
• Max Object Size is 5TB
• If uploading more than 5GB, must use “multi-part upload”
• The key is composed of prefix + object name s3://mybucket/
my_folder1/another_folder/my_file.txt (THIS)

Q

S3 Security

A

• User based = IAM policies for users and for services
• Resource Based = Bucket Policies + Public Access (allows cross account) – Object Access Control List (ACL) – Bucket Access Control List (ACL)
• Encryption: encrypt objects in Amazon S3 using encryption keys

Q

S3 Bucket Policies

A

• JSON based policies

Use S3 bucket for policy to:
• Grant public access to the bucket
• Force objects to be encrypted at upload
• Grant access to another account (Cross
Account

Q

S3 Access Logs

A

• For audit purposes
• Any request made to S3, from any account, authorized or denied, will be logged into another S3 bucket
• Very helpful to come down to the root cause of an issue, or audit usage, view suspicious patterns, etc…

Q

S3 Replication (CRR & SRR)

A

• Must enable versioning in source and destination
• Buckets can be in different accounts
• Copying is asynchronous
• Must give proper IAM permissions to S3

• Cross-Region Replication (CRR) - Use cases: compliance, lower latency access, replication across accounts
• Same-Region Replication (SRR) – Use cases: log aggregation, live replication

Q

S3 Storage Classes – Infrequent Access

A

• For data that is less frequently accessed, but requires rapid access when needed
• Lower cost than S3 Standard

• S3 Standard-IA = 99.9% Availability & Use cases: Disaster Recovery, backups
• S3 One Zone-IA = In a single AZ, 99.5% Availability, Use Cases: Storing secondary backup copies of on-premise data, or data you can recreate

Q

Amazon S3 Glacier Storage Classes

A

• Low-cost object storage meant for archiving / backup
• Pricing: price for storage + object retrieval cost

17
Q

Amazon S3 Glacier Storage Classes 2

A

Amazon S3 Glacier Instant Retrieval
• Millisecond retrieval
• Minimum storage duration of 90 days

Amazon S3 Glacier Flexible Retrieval
• Expedited (1 to 5 minutes), Standard (3 to 5
hours), Bulk (5 to 12 hours) – free
• Minimum storage duration of 90 days

Amazon S3 Glacier Deep Archive
• For long term storage
• Standard (12 hours), Bulk (48 hours)
• Minimum storage duration of 180 days

18
Q

S3 Intelligent-Tiering

A

• Small monthly monitoring and auto-tiering fee
• Moves objects automatically between Access Tiers based on usage
• There are no retrieval charges in S3 Intelligent-Tiering

19
Q

S3 Object Lock & Glacier Vault Lock

A

S3 Object Lock:
• Adopt a WORM (Write Once Read
Many) model
• Block an object version deletion for a
specified amount of time

Glacier Vault Lock:
• Adopt a WORM model
• Lock the policy for future edits (can no
longer be changed)
• Helpful for compliance and data retention

20
Q

S3 Encryption

A

• No Encryption
• Server-Side Encryption = Server encrypts the file after receiving it
• Client-Side Encryption = User upload encrypts the file before uploading it

21
Q

AWS Snow Family

A

• Highly-secure, portable devices to collect and process data at the edge, and migrate data into and out of AWS
• Data migration: Snowcone, Snowball Edge, Snowmobile
• Edge computing: Snowcone, Snowball Edge

22
Q

AWS Snowcone

A

• Small, portable computing, anywhere, rugged & secure, withstands harsh environments
• Device used for edge computing, storage, and data transfer
• 8 TBs of usable storage & up to 24TB online and offline
• Can be sent back to AWS offline, or connect it to
internet and use AWS DataSync to send data

23
Q

Snowball Edge (for data transfers)

A

• Physical data transport solution: move TBs or PBs of data in or out of AWS
• Provide block storage and Amazon S3
-compatible object storage
• 80TB usable storage - Up to petabytes offline

S3 compatible object storage
• Snowball Edge Compute Optimized
• 42 TB of HDD capacity for block volume and
S3 compatible object storage

25
Q

AWS Snowmobile

A

• Transfer up to exabytes of data
• Each Snowmobile has 100 PB of capacity
• High security: temperature controlled, GPS, 24/7 video surveillance
• Better than Snowball if you transfer more than 10 PB

26
Q

What is Edge Computing?

A

• Process data while it’s being created on an edge location
• These locations may have limited internet access or no easy access to computing power
• We setup a Snowball Edge / Snowcone device to do edge computing
• Use cases of Edge Computing: Preprocess data, Machine learning and Transcoding media streams

27
Q

Snow Family – Edge Computing

A

• Snowcone = 2 CPUs, 4 GB of memory, wired or wireless access
• Snowball Edge – C-O = 52 vCPUs, 208 GiB of RAM
• Snowball Edge – S-O = Up to 40 vCPUs, 80 GiB of RAM

28
Q

AWS OpsHub

A

You can use AWS OpsHub (a software you install on your computer / laptop) to manage your Snow Family Device

29
Q

AWS Storage Gateway

A

Hybrid storage service to allow on- premises to seamlessly use the AWS Cloud
