Ali cloud file storage (Network Attached Storage, referred to as NAS) is oriented Ali cloud ECS example, file storage service computing nodes E-HPC and the container services.
definition
Ali cloud file storage NAS is a shared access, flexible extension, high reliability and high-performance distributed file system. It is based on POSIX file interface, natural adaptation native operating system to provide shared access while maintaining data consistency and locks are mutually exclusive.
NAS provides a simple, scalable file storage for use in conjunction with ECS, ECS instances can simultaneously access multiple NAS file systems, and storage capacity as you add and delete files elasticity automatically grow and shrink, as in multiple instances or workloads and applications running on the server provides a common data source.
NAS provides the displacement, speed and performance type type memory type.
NAS provides a wealth of application scenarios.
Advantage
NAS on cost, safety, simplicity, reliability, and performance has its own advantages.
- cost
- A NAS file system can be mounted simultaneously on a plurality of computing nodes, these nodes share access, thus saving the cost of a large number of copies and synchronization.
- Performance of a single NAS file system with the storage capacity can be linearly extended, so that end users need to purchase file storage device, significantly reducing the cost of the hardware.
- File storage using NAS, you can simply use the storage space for the file system to pay, do not need to store pre-configured, and set the minimum cost or expense does not exist.
- NAS high reliability can reduce data security risks, which significantly reduces maintenance costs.
- simple
A key to create a file system, file system maintenance without the need to deploy.
- Safety
RAM-based resource access control. Network access quarantine VPC file management, transport encryption and encrypted storage to protect data from being stolen or tampered with.
- High reliability
NAS to provide 99.999999999% data reliability, can effectively reduce data security risks.
- high performance
Distributed architecture based file system, with the capacity growth performance scales linearly, providing much higher than traditional storage performance.
- compatibility
- NAS file storage protocol to provide good compatibility, support NFS and SMB protocol scheme, POSIX-compliant file system access semantics, providing strong data consistency and file locking.
- In NAS, the file after any modifications successfully, the user can immediately see the result of modifications, user-friendly real-time changes to store content.
