Q

Volume Encryption

A

Uses EC2 host hardware to encrypt Data At Rest and In Transit between EBS and EC2 Instance

21
Q

Legacy Non-EBS-Optimized Instance

A

Uses a shared network path for data and storage cummunications

22
Q

EBS-Optimized Mode

A

Adds optimization and dedicated communication paths for storage and traditional data networking

23
Q

Enhonced Networking

A

Uses SR-IOV which allows a single physical network card to appear as multiple physical devices

24
Q

Single Root Input Output Virtulization (SR-IOV)

A

Each instance can be given one of these fake physical devices

25
Cluster Placement Group (CPG)
Places Instances Physically Near Each Other in a Single Avalibility Zone (AZ)
26
Partition Placement Group (PPG)
- Instances are deployed and seperated into partitions - Max 7 per AZ - Can span ultiple AZs ina Region
27
Spread Placement Group (SPG)
- Max 7 Instances per AZ that need to be seperated | - Each instance occupies a partition and has isolated fault domain
28
Spread Placement Group (SPG) great for?
- Email - Domain Controllers - File Servers - Application HA pairs
29
Spot Instance
- Cunsomption of spare AWS capacity
30
Spot Fleet
Pool of instances of certain types and size aiming for a given "capacity"
31
Reserved Instance
Lock in a reduced rate for 1 or 3 years
32
Reserved Instance used for?
- Long- Running - Understood - Consistent Workloads
33
Dedicated Hosts
EC2 Hosts for a given type and size that can be dedicated
34
Amazon Machine Image (AMI)
Used to build Instances
35
Amazon Machine Image (AMI) stores Snapshots of?
- EBS Volumes - Permissions - Block Device Mapping
36
Amazon Machine Image (AMI) can be
- Shared - Free - Paid - Copied to other AWS Regions
37
Bootstrapping
Instructions are executed on an Instance during its launch process
38
Bootstrapping is used to
- Configure an Instance - Perform Software Instillation - Add App configurations
39
EC2 Instance Roles
IAM Roles that can be assumed by EC2 using INstance Profiles
40
Instance Profile
Either created automatically when using the console UI or Manually using CLI
41
Legacy Non-EBS-Optimized Instances
Used to share networking paths for data & storage comunications
42
EBS-Optimized Mode
Addsoptimization and dedicated communication paths for storage and data networking
43
Enhanced Networking
Uses SR-IOV allowing a single physical network card to appear as multiple physical devices
44
Single Root Inpout Outpu Virtulization (SR-IOV)
Instances can be given one of these fake physical devices
45
Single Root Inpout Outpu Virtulization (SR-IOV) results in
- Faster Transfer Rates - Lower CPU Usage - Lower Consistent Latency
46
Cluster Placement Group (CPG)
Plcaes Instances Physically near each other in a single AZ
47
Partition Placement Group (PPG)
Instances are deployed and seperated into Partitions of max 7 per AZ
48
Containers
A package that contains Apps, Libraries, or File Systems
49
Elastic Container Systems (ECS)
Managed Container Engine
