Launch permissions that control which AWS accounts can use the AMI to launch instances; A block device mapping that specifies the volumes to attach to the instance when it's launched; The AMI filesystem is compressed, encrypted, signed, split into a series of 10 MB chunks and uploaded into Amazon S3 for storage. An XML manifest file stores ...
Amazon Elastic Block Store. Amazon Elastic Block Store (EBS) provides raw block-level storage that can be attached to Amazon EC2 instances and is used by Amazon Relational Database Service (RDS). [1] It is one of the two block-storage options offered by AWS, with the other being the EC2 Instance Store. [2]
DRBD layers logical block devices (conventionally named /dev/drbdX, where X is the device minor number) over existing local block devices on participating cluster nodes. Writes to the primary node are transferred to the lower-level block device and simultaneously propagated to the secondary node(s). The secondary node(s) then transfers data to ...
Amazon EBS (elastic block store) is an example of a cloud block store. [2] Cloud block-level storage will usually offer facilities such as replication for reliability, or backup services. [3] Block-level storage is in contrast to an object store or 'bucket store', such as Amazon S3 (simple storage service), or to a database. These operate at a ...
The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices. It forms the foundation of the logical volume manager (LVM), software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots .
These block devices can then be used like any raw block device. In a typical use case, this would include formatting the device with a filesystem and mounting it. In addition, EBS supports a number of advanced storage features, including snapshotting and cloning.
With DDM (Dynamic Device Mapping) Technology, the communication between shared peripherals and all connected systems are maintained 100% of the time, even as a user switches between the KVM ports. This makes generic device emulation unnecessary as the DDM allows each connected computer system to believe all connected I/O devices are remaining ...
Network block device servers are typically implemented as a userspace program running on a general-purpose computer. All of the function specific to network block device servers can reside in a userspace process because the process communicates with the client via conventional sockets and accesses the storage via a conventional file system ...
