The D2 instances are backed by hard disk drives and offer large-volume, low-cost persistent storage with up to 48TB per instance. In addition to selecting the right EC2 instance family and type, other resourcing considerations include:. A few patterns emerge when describing the different kinds of instances you can use in AWS.
First, there are a large number of instances. Even within a single family of instances, there can be up to 18 different configurations. This makes it difficult to find the optimal instance type for a given workload. For example, you may have a compute-intensive application, but you may not be sure if you should use a compute-optimized instance or an accelerated instance.
If the application makes many floating point calculations and the code can take advantage of a GPU, an accelerated instance may be the best option.
These characteristics are key to doing accurate comparisons between different instance types, which can help you decide which kind of instance is best for a particular workload. Also consider technical constraints on different instances, such as which images run on particular instances; if EBS and networking can burst; and the limits of local storage.
Finally, consider business policies that might be in effect that limit your options. The wide array of choices in choosing an instance type can be bewildering. Stream is used to measure the sustained memory bandwidth. In this test, the r5 instances performed the best as expected. R5 instances are memory-optimized and have the most amount of memory as compared to M5 and C5.
The M5 instances have more memory available than the C5 instances and have better memory performance than the C5 instances. We compared the prices between these instance families by looking at the price per hour for each instance type. C5 instances are the cheapest amongst the three instance families whereas the R5 instances are the most expensive. The new C5 instances offer the best processor performance as well as price and should be the go-to instance type for most use-cases.
If the use-case requires a lot of memory, then the choice becomes either between M5 and R5. Do not use this product if you are pregnant, nursing, or are currently taking nitrates for chest pain, or if you are taking medication used to treat erectile dysfunction such as PDE-5 inhibitors.

Do not use if the safety seal is broken or missing. Until June 30th, , all new and existing Amazon Web Services customers can try the t4g. With M5d instances, local NVMe-based SSDs are physically connected to the host server and provide block-level storage that is coupled to the lifetime of the M5 instance. T3 instances are the next generation low cost burstable general-purpose instance type that provide a baseline level of CPU performance with the ability to burst CPU usage at any time for as long as required.
T3 instances are designed for applications with moderate CPU usage that experience temporary spikes in use. C5 Instances are optimized for compute-intensive workloads and deliver cost-effective high performance at a low price per compute ratio.
With C5d instances, local NVMe-based SSDs are physically connected to the host server and provide block-level storage that is coupled to the lifetime of the C5 instance.
With R5d instances, local NVMe-based SSDs are physically connected to the host server and provide block-level storage that is coupled to the lifetime of the R5 instance.
