S3 and Amazon EFS.
What does AS2 stand for and what is its primary use?
Applicability Statement 2; it enables secure and reliable messaging over HTTP/S and is often used for EDI (Electronic Data Interchange) transactions
What is the purpose of AWS Snow Family?
To physically move data in or out of the cloud when moving it over the internet or private connection is slow, difficult, or costly.
To which service is data delivered when using AWS Snow Family?
Amazon S3.
Name the three devices in the AWS Snow Family.
Snowcone, Snowball Edge, Snowmobile
What is AWS Snowcone used for?
Edge computing and data transfer.
What are the data transfer methods for AWS Snowcone?
Physically shipping the device back to AWS. Using AWS DataSync which runs on the device’s compute.
What are the two variants of AWS Snowcone and their storage capacities?
Snowcone - 8 TB HDD, Snowcone SSD - 14 TB SSD
What key features does AWS Snowcone offer?
Collecting IoT data using AWS IoT Greengrass, Edge computing workloads using EC2 instances, Multiple layers of encryption
What additional capabilities does Snowball Edge have compared to Snowcone?
More local processing, edge-computing workloads, and device configuration options.
What are the configuration options for Snowball Edge?
Storage-Optimized 80 TB, Storage-Optimized 210 TB, Storage-Optimized with EC2-Compatible Compute: 80 TB, 40 vCPUs, and 80 GB of memory, Compute-Optimized: 104 vCPUs, 416 GB of memory, and 28 TB of dedicated NVMe SSD, Compute-Optimized with GPU: includes the same GPU as in P3 instance type
What is AWS Snowmobile?
A shipping container pulled by a semi-trailer truck capable of transferring up to 100 PB of data.
Where is data imported when using Snowmobile?
Either to S3 or Glacier.
What does IOPS stand for and what does it measure?
Input/Output Per Second (IOPS); it measures the speed of non-contiguous reads and writes.
What is Throughput in the context of AWS storage?
The data transfer rate.
What does Bandwidth measure?
The total possible speed of data movement.
What are the characteristics of the gp2 volume type?
General Purpose SSD; used for general workloads like virtual desktops, medium-size databases, low-latency applications, boot volumes, and development/test environments.
How does gp3 differ from gp2?
gp3 is 20% cheaper per GB than gp2 but serves the same use cases.
What is io1 used for and what are its key features?
Provisioned IOPS SSD; used for workloads requiring sustained IOPS performance or more than 16,000 IOPS, such as I/O-intensive databases.
What is unique about io2 compared to io1?
io2 is more durable than io1. Volumes created after 21.11.2023 are io2 Block Express, which offers higher throughput and IOPS.
What are io2 Block Express volumes known for?
Higher throughput, higher IOPS, and larger storage capacity.
What is the purpose of sc1 and its key characteristics?
Cold HDD; lowest cost HDD volume for infrequently accessed workloads. It is throughput-oriented storage.
What is the st1 volume type and its primary use case?
Throughput Optimized HDD; a magnetic drive optimized for quick throughput, used for big data, data warehouses, and log processing.
Describe the standard (Magnetic) volume type.
Previous generation HDD; used for workloads where data is infrequently accessed.
What is the durability range for gp2, gp3, io1, io2, st1, and sc1?
99.8% - 99.9%.
What is the durability of io2 Block Express volumes?
99.999%.
What is the volume size range for gp2 and gp3?
1 GiB - 16 TiB.
What is the maximum IOPS for io1 and io2 Block Express?
io1 has a max IOPS of 64,000, and io2 Block Express has a max IOPS of 256,000.
What is the maximum throughput for gp3 and io2 Block Express?
gp3 has a maximum throughput of 1,000 MiB/s, and io2 Block Express has a maximum throughput of 4,000 MiB/s.
Which volume types support EBS multi-attach?
io1 and io2 Block Express support EBS multi-attach.
Which volume types support NVMe Reserved?
io1 and io2 Block Express support NVMe Reserved
Which volume types support Boot volumes?
gp2, gp3, io1, and io2 Block Express support Boot volumes.
Which volume types are not supported for Boot volumes?
sc1, st1, and standard (Magnetic) are not supported for Boot volumes
