2/29/2024 0 Comments Ephemeral volume aws![]() If you can't afford to lose any data on an I3 instance storage, don't use it. At the same time, if you were storing some permanent and unique data, you are in a big-big trouble. Now, if that drive was used for some temporary storage or it’s data is quickly “replenish-able”, you are fine. ![]() ![]() Stop an instance and you will effectively lose an access to that I3 drive, which is akin to loss of data. What is not very common is to lose all your data due to saving money and downgrade/upgrade. Why would you stop AWS EC2 instance you might ask? It's very common to stop an instance to save money or to downgrade/upgrade an instance. AWS I3 family storage is persistent as long the instance it's bound to is up and running. This instance storage will in fact lose data if AWS EC2 instance is stopped. The I3 instance family looks solid, so what is the problem? While NVMe SSD storage is persistent and would NOT lose data due to power outage, it's not completely persistent due to it's AWS provisioning (it's actually, a volatile temporary ephemeral storage). The following matrix provides the different bundled resources (Fig #2) available in the family. Overall, I3 instance family's main purpose is a storage intensive application at a low cost. If you get confused by NVME, this means that the drive will not lose data while the power is out. I3 is built with Non-Volatile Memory Express (NVMe) SSDs to achieve these goals. The I3 instance family provides storage optimized instances designed for high transactions, low latency workloads, and high IOPS. the I3 instance type family, its little-known problem, and the solution in the form of Elastic Block Storage (a.k.a. This blog post is going to talk about a storage optimized instance. You can see the different types in Fig 1. To cater to different clients' needs, AWS provides various instance types that are either general instance or specific-purpose instances (focused on CPU, RAM, IO). EC2) is a service that lets anyone with a credit card rent a virtualized server from Amazon. Amazon Web Services Elastic Cloud Computing (a.k.a.
