Local NVMe Storage: An additional feature on C5 Instances


 EC2 clients keep increasing and so do their needs. This has seen a steady rise in the EC2 instance types being released to the market. The C5 instances recently released have been tailor-made to deal with the storage challenge experienced by a number of AWS customers.

The C5d instances have been equipped with local NVMe storage that makes them suitable for a number of applications including video processing and ad encoding. It also allows for multiplayer gaming as well as analytics which could either be real-time or distributed. Log and batch processing can also be efficiently performed with this instance. 

Most of these applications work best in local storage with fast speeds. Temporary and I/O storage is needed for media processing to run well. Computer resources are best utilized when volatile data and intermediate files are flushed to available disc space. On the other hand the input as well as the output data are kept in the form of Amazon S3 (Simple Storage Service) objects.

C5d Instances 

The Local NVMe storage added to C5 instances enables the aforementioned applications to run with little hustle if any at all. The instances also double up for numerous other applications that you will choose. The storage unit is physically attached to the host server. 

They come in different sizes ranging from the C5d.large to the C5d.18x large each having different specifications. The latter requires RAM of 144 GB to operate well while the former only needs 4GB RAM. The network and EBS bandwidth requirements also vary considerably.

They provide up to 2 × 900 GB of local storage that is based on the NVMe SSD storage. They also have different vCPUs depending on their size with the largest having 72 while the smallest has 2 vCPUs. 

Ubuntu, SUSE, Amazon Linux, RHEL, Microsoft Windows along with CentOS AMIs have drivers that are compatible to the NVMe and the Elastic Network Adapter. You can therefore use them once you have the C5d instance in place. 

The C5 and C5d instances only differ on the local storage present in the latter. Their specifications are largely similar. They are both suitable for Amazon EC2. The Intel Turbo Boost Technology allows you to enjoy processor speeds of up to 3.5 GHz with two cores running concurrently. The Intel Xeon Processors power the two instances. 

The local NVMe storage devices 

The NVMe device's lifetime is dependent on the lifetime of the instance. In case the instance is done away with then the local storage device will be terminated. A distinctive key is given to the devices which are also encrypted by the XTS-AES-256 block code. As with other devices the key is lost when the device is destroyed. 

Once your operating system is ready for use the local storage will appear. You do not need to worry about naming the device when the instance is launched on your machine. 

Clients with computer-intensive workloads are the greatest beneficiaries of the additional storage that the C5d instance offers. The instances are already available in the Europe AWS regions, the US as well as in Canada and can easily be purchased. The AWS Management Console is a good place to get access to the new EC2 instances.
