NICE DCV through the Web Browser for Linux and Windows

Previously there were different ways of connecting to instances for Linux and Windows. For Linux it was mainly VNC or SSH. For Windows you had the choice of Remote Desktop or NICE DCV. 

In order to take advantage of GPU graphics instances for products such as Discovery Live or ANSYS AIM, the best option was NICE DCV.

However NICE DCV required non standard ports to be opened, and also required the installation of software on your local machine. It also required licences. This gave problems for many IT and finance departments.

Amazon have acquired NICE DCV so now they are providing an updated version of NICE DCV that works directly from the browser over the standard https port (443).  And it’s completely free on EC2 instances!

CADFEM have packaged this up nicely for you so that you can use a unified connection mechanism to both Windows and Linux instances.  Remote Desktop, SSH and VNC will still be supported for now, but we are considering discontinuing it in the future.

Enhanced Networking

The CADFEM Self Service Portal now supports Enhanced Networking. Enhanced Networking is necessary to launch the new C5 and M5 instance types.

Enhanced networking uses single root I/O virtualization (SR-IOV) to provide high-performance networking capabilities on supported instance types. SR-IOV is a method of device virtualization that provides higher I/O performance and lower CPU utilization when compared to traditional virtualized network interfaces. Enhanced networking provides higher bandwidth, higher packet per second (PPS) performance, and consistently lower inter-instance latencies. There is no additional charge for using enhanced networking.

The Elastic Network Adapter (ENA) supports network speeds of up to 25 Gbps for supported instance types. This compares with the various Infiniband speeds as shown in the table below:

ENA FDR FDR-10 QDR DDR SDR
25 Gbps 54 Gbps 40 Gbps 32 Gbps 16 Gbps 8 Gbps

C5, F1, G3, H1, I3, m4.16xlarge, M5, P2, P3, R4, and X1 instances use the Elastic Network Adapter for enhanced networking.

Amazon have said that ENA will support up to 60 Gbps by the end of the year!

New C5 and M5 Instance Types

Amazon have released a new generation of C5 and M5 instances, with superior speed and network connectivity to the old C4 and M4 instance types.

We have worked hard to implement these on the Self Service Portal and they are now ready for prime time.

Model Real CPU Cores Memory (GiB) Linux Price (Ireland)
c5.large 1 4 $0.096
c5.xlarge 2 8  $0.192
c5.2xlarge 4 16  $0.384
c5.4xlarge 8 32  $0.768
c5.9xlarge 18 72  $1.728
c5.18xlarge 36 144  $3.456
Model Real CPU Cores Memory (GiB) Linux Price (Ireland)
m5.large 1 8  $0.107
m5.xlarge 2 16  $0.214

And also remember these instance types support networking speeds of up to 25 Gbps!

Standardised Password Generation

We have made the Get Password function now work in the same way for Linux and Windows.  This allows you to click “Get Password” regardless which OS image you are launching.
