Intro to VPN

• VPC != VPN

• IPsec authentication & encryption

• AWS options

• AWS Managed VPN

• Software VPN (EC2)

Intro to AWS Direct Connect (DX)

• Offered since 2011

• Private connection, separate from Internet

• Consistent network experience

• Connect through one of 40 locations

• Each connection connects into 1 AWS Region

• Multiple options for each AWS Region

Resiliency

• Easy install, minutes to setup

• NAT-T, AES-256, SHA-2 and latest

DH groups

• Static (1 prefix) or BGP (<100

prefixes)

• Repeat for every VPC

• $0.05 per VPN connection hour

• Data transfer

• Leverage both VGW endpoints (2

tunnels per VPC)

• Think about CGW redundancy (4

tunnels per VPC)

• Multi Gbps can be achieved per

VPC (limited at VGW)

Resiliency

• Any open-source or commercial vendor

• Opens up proprietary feature sets

• Customer responsible for HA and scaling

• Advanced solutions can be built using

automation

• Vendor licensing

• EC2 hourly cost

• High availability cost

• Data transfer

• VPC endpoint HA achieved by

additional EC2 instance in 2nd AZ

• Customer-side HA also recommended

• Defined by EC2 instance size & type

• Multi Gbps can be achieved per

VPN instance (for all tunnels)

• Multiple instances for the same VPC

are possible

DX physical connectivity considerations

AWS account that owns the DX port?

Adding/removing virtual interfaces?

Routing ownership?

End-to-end costs?









Customer’s AWS account, interface control, routing. Cost: port + data transfer






Same as #1; add circuit cost. Sub 1-Gig can create only 1 virtual interface







Depends on provider’s offering







Depends on provider’s offering

Direct Connect cost considerations

Port hour + data transfer

Data in $0; data out differs by region

Factor in circuit costs

Calculate data center Internet costs (VPN)

Resiliency

• 14 AWS regions, 40 POPs worldwide

• LOA provided within up to 72 hours

• Lead time of circuit build-out could take

weeks

• Port hours

• Data out transfer

• Service provider circuit / MPLS

• Colo cage (if applicable)

2 x DX in 2 locations + VPN

2 x DX in 2 separate locations

2 x DX in 1 DX location

DX + VPN

DX

• 1 Gbps or 10 Gbps ports

• 100, 200, 300, 400 or 500 Mbps

ports available through partners

• Equal-cost multipath via BGP means

2x10 G = 20 Gbps

Adapting the architecture

• Start with 1 AWS managed VPN

• Use VPN while DX is being built out

• Port hour charges begin when DX is up or 90 days

• DX is favored over VPN when both exist

• Add additional DX ports for resiliency / bandwidth

• Plan for failure, including facility failure

• Control traffic flow both ways using BGP and routing

• Raise support cases with AWS with any questions

• Connect using VPN in parallel to DX build out

• More DX locations = more resiliency

• Plan and test for resiliency, and repeat

periodically

• Talk to your AWS team
