#aws #cloud #networking
AWS Direct Connect is a network service that provides an alternative to using the Internet to utilize AWS cloud services. AWS Direct Connect enables customers to have low latency, secure and private connections to AWS for workloads which require higher speed or lower latency than the internet.
• Private connectivity between AWS and your data center / office • Consistent network experience – increased speed/latency & bandwidth/throughput • Lower costs for organizations that transfer large volumes of data
# Private VIF (Single VPC)
# Multiple VIF (Multiple VPC)
- Speeds from 50Mbps to 500Mbps can also be accessed via an APN partner (uses hosted VIFs or hosted connections): • A hosted VIF is a single VIF that is shared with other customers (shared bandwidth) • A hosted connection is a DX connection with a single VIF dedicated to you
- DX Connections are not encrypted.
- Use an IPSec S2S VPN connection over a VIF for encryption.
- Link aggregation groups (LAGs) can be used to combine multiple physical connections into a single logical connection using LACP – provides improved speed
# DX - Native High Availability
Redundant DX connections through secundary DX location
Redundant Connection through a VPN
don’t use this setup if bandwidth is above 1GBps.
