Exam Notes:
- Terabytes of data? Direct Connect.
- Remember the set up time required - Weeks to months.
- Connections over a Direct Connect are not encrypted.
- Private VIFs are a one-to-one connection.
- There is a charge per hour for the port.
- Data transfer out is charged.
- Routes advertised over BGP.
- Can create multiple Direct Connects to a single DX location.
- Important options:
- Speed: 1Gbps or 10Gbps
- DX location
- AWS allocates a DX port in the DX location
- 1000-Base-LX or 10GBASE-LR
- Request a cross-connect into your network (Your router).
- Private VIF connects to a Virtual Private Gateway (VGW).
- Public VIF, public zone services but not internet.
- From AWS:
- 1Gbps => 10Gbps
- From Partner:
- Ranges of speeds: 50Mbps => 10Gbps
- Hosted connection - a DX connection with one .
- Hosted VIF - Single VIF with shared bandwidth*
- MISC:
- Direct connect offers no encryption!
- Any data transiting unless encrypted by an application is not encrypted.
- Provision DX, provision public VIF and the create a site-to-site VPN across the VPN.
- No sharing internet data cap.
- No sharing internet bandwidth.
- No transit over the internet - low/consistent latency.
- Cheaper data transfer / faster speeds.
- Direct connect offers no encryption!
- Link Aggregation Groups (LAGS):
- Multiple physical connections act as one - Speed * n
- Provide less admin overhead, more speed, but not really more resilience.
- Max of 4 connections per LAG
- All must be same speed
- Must terminate at same location.
- Lag active as long as MinimumLinks attribute is healthy.
- Multiple physical connections act as one - Speed * n
- Transit VIFS:
- Public VIF can access all AWS public .
- VLAN and BGP session.
- Private VIF can only access VPC's in the same AWS region via VGWs.
- Public VIF can access all AWS public .
- DX Gateway:
