[14] It was announced in June 2018, and is updated on a regular basis. [15] Amazon Linux 2023 was the next version, which launched alongside a new two-yearly release ...
Instance-store volumes are temporary storage, which survive rebooting an EC2 instance, but when the instance is stopped or terminated (e.g., by an API call, or due to a failure), this store is lost. The Amazon Elastic Block Store (EBS) provides raw block devices that can be attached to Amazon EC2 instances. These block devices can then be used ...
AWS Graviton is a family of 64-bit ARM-based CPUs designed by the Amazon Web Services (AWS) subsidiary Annapurna Labs. The processor family is distinguished by its lower energy use relative to x86-64 , static clock rates , and lack of simultaneous multithreading .
Eucalyptus commands can manage either Amazon or Eucalyptus instances. Users can also move instances between a Eucalyptus private cloud and the Amazon Elastic Compute Cloud to create a hybrid cloud. Hardware virtualization isolates applications from computer hardware details. [10] Eucalyptus architecture overview. Eucalyptus uses the terminology ...
Each AWS Lambda instance runs within a lightweight, isolated environment powered by Firecracker microVMs. These microVMs are initialized with a runtime environment based on Amazon Linux (Amazon Linux AMI or Amazon Linux 2), a custom Linux distribution developed by AWS. Firecracker provides hardware-virtualization-based isolation, aiming to ...
OS-level virtualization is an operating system (OS) virtualization paradigm in which the kernel allows the existence of multiple isolated user space instances, including containers (LXC, Solaris Containers, AIX WPARs, HP-UX SRP Containers, Docker, Podman), zones (Solaris Containers), virtual private servers (), partitions, virtual environments (VEs), virtual kernels (DragonFly BSD), and jails ...

If that happens, each node in the cluster may mistakenly decide that every other node has gone down and attempt to start services that other nodes are still running. Having duplicate instances of services may cause data corruption on the shared storage. HA clusters often also use quorum witness storage (local or cloud) to avoid this scenario. A ...
