-AWS Direct Connect-
-Overview-
This customer had existing VPN’s to their AWS VPC. These vpns where routing over the public internet and regularly ran into link saturation and latency issues affecting time sensitive applications hosted in the cloud.
-Objectives-
Produce HLD and LLD of traffic flow
Design and implement Highly Available connectivity to AWS
Improve latency for application responsiveness
Increase throughput for high traffic periods and future growth
-Solution-
Firstly, like we always do at Networks Revived. We created a full high & low level network design which documented full traffic flow including any information needed for operational teams to support.
We decided to go with an AWS Direct Connect solution. This consisted of two redundant low latency MPLS connections to Equinix for public cloud interconnectivity. Utilising Equinix’s Software Defined Fabric allowed us to terminate MPLS connectivity from our OnPremise DC to two different geographical Equinix datacentres. From there a 5gbps cross connect direct into AWS infrastructure was installed.
Quality of service was then implemented through the path using the DiffServ method for the latency sensitive applications.
-Outcome-
Multiple benefits were achieved for the customer during this project including hitting our target of objectives.
Full HLD and LLD for supporting technical teams provided.
Latency for time sensitive applications improved with the MPLS circuits and QOS
Increased bandwidth to AWS now possible with implementation of Direct Connect and decommission of the IPSEC vpns (limited to 1.25Gbps). This will improve performance for high traffic periods plus facilitating future growth and expansion into AWS for the customer.
