Elastic Network Adaptor provides high throughput and low latency where at the same time it decreases the load on the host processor. It is basically designed to work great in the presence of various vCPUs that is also with the intelligent packet routing backed up by receiving queues and multiple transmit. To use the Elastic Network Adapter you need configure the AMIs and the current generation Elastic Cloud Compute instances.
Amazon Web Services has opened the floodgate which will provide you access to more network bandwidth in all the AWS Regions.
Elastic Cloud Compute to Simple Storage Service – Traffic to and from the Amazon S3 can now benefit of up to 25 Gbps of bandwidth. Earlier the traffic of such type has only access up to 5 Gbps of bandwidth. This will an added advantage applications that access large amounts of data in Simple Storage Service or that utilises Amazon S3 which makes use of restore and backup.
Elastic Cloud Compute to Elastic Cloud Compute – Traffic to and from Elastic Cloud Compute Instance in different or same Availability Zones within a region can benefit up to 5 Gbps of bandwidth for single-flow traffic or 25 Gbps of bandwidth for multi-flow traffic by utilising the private IPv4 or IPv6 addresses.
Elastic Cloud Compute to Elastic Cloud Compute (Cluster Placement Group) – Traffic to and from Elastic Cloud Compute instances within a cluster placement group can take benefit up to 10 Gbps of lower latency bandwidth for single flow traffic and 25 Gbps of lower latency bandwidth for multi-flow traffic.
Use the latest Elastic Network Adapter AMIs on current generation Elastic Cloud Compute Instances to take benefits of the additional bandwidth. Elastic Network Adapter AMIs are now available for Windows Server (2008 R2, 2012, 2012 R2 and 2016), Ubuntu 14.04 and 16.04, SLES 12, RHEL 7.4 and Amazon Linux.
Elastic Network Adapter is launched to deliver better support for high-performance networking. It provides up to 20 Gbps of low latency performance, consistent when used with the Placement Group. Elastic Network Adapter scales as the network bandwidth grows as the vCPU count increases which will enable you to benefit from the higher bandwidth options in the future without any need to make changes to the configuration which was earlier required by network interfaces or you don’t need to install new drivers.
To use the Elastic Network Adapter you to need to utilise the new driver and tag the AMI while having the ENA support. The new driver is now available in the latest Amazon Linux AMIs and it will be available in the Windows AMIs soon. The Open Source Linux driver is now available in source form on GitHub for usage in the AMIs. Intel Data Plane Developer Kit is available for the developers that are creating network processing applications such as virtual routers and load balancers. When you are generating an AMI you will need to set enaSupport attribute when you are registering it.
