Global Infrastructure Flashcards
1
Q
Global application properties
A
- multiple geos
- Regions and/or Edges
- Decreased latency
- DR (region failure)
- Attack protection
2
Q
AWS Global Infrastructure
A
- Regions
- AZs
- Edge locations. (PoPs)
- Points of presence
- Local zones
3
Q
Route 53
A
Managed DNS (global)
- A record (IP to domain)
- AAAA record (IP to domain IPV6)
- CNAME hostname to hostname
- Alias hostname to AWS resource
4
Q
Routing policies
A
Policies
- Simple (no health checks)
- Weighted
- Latency
- Failover routing policy
5
Q
CloudFront
A
Global content delivery network (CDN)
- Edge location deployment cache
- Lower latency
- 216+ PoPs (edge locations)
- DDoS protection (with Shield and WAF)
6
Q
CloudFront Origins
A
S3 Bucket
- For distributing and caching files at the edge
- Origin Access Control (OAC)
- S3 bucket policy
- Can be ingress
HTTP
- ALB
- EC2 instance
- S3 website (must enable static site on bucket)
7
Q
S3 Transfer Acceleration
A
- Increase transfer speed to S3 bucket
- Use edge location that forwards to S3
8
Q
AWS Global Accelerator
A
- Improve availability using AWS network
- Leverage AWS internal network
- Uses 2 static Anycast IPs
- Edges send traffic to application
9
Q
AWS Outposts
A
- Hybrid cloud (cloud + on-prem)
- Server racks to make AWS on-prem
- Must provide physical security for rack
10
Q
AWS Outpost Benefits
A
- Low latency
- Local data processing
- Data residency
- Easy migration
- Fully managed
- ec3, ebs, s3, eks, ecs, rds, emr
11
Q
AWS Wavelength
A
5G
- Infra embedded in telecom 5g edge locations
- Brings AWS to edge of 5G
- EC2, EBS, VPC, etc.
- Ultra low latency
- Traffic never leaves CSP (comm service provider)
- High bandwidth
- No added charges or service agreements
12
Q
AWS Local Zones
A
- Extend your VPC to more regions
- EC2 RDS, ECS, ElastiCache, DirectConnect
13
Q
Global Application Architecture Patterns
A
- Single region, single AZ
- Single region, multi AZ
- Multi-region, active-passive
- Multi-region, active-active
