Product introduction- Apsara File Storage NAS
- 1. Product Introduction Apsara File Storage NAS Jed G. Concepcion Alibaba Cloud MVP
- 2. What is APSARA File Storage NAS? • NAS is a cloud service that provides file storage for compute nodes. These compute nodes include Elastic Compute Service (ECS) instances, E-HPC nodes, and Alibaba Cloud Container Service for Kubernetes (ACK) nodes. • NAS is a distributed file system that provides several benefits. These benefits include shared access, scalability, high availability, and high performance. Based on POSIX file APIs, NAS is compatible with native operating systems. This ensures data consistency and exclusive locks during shared access. • NAS provides scalable file systems and allows simultaneous access to a file system from multiple ECS instances. Storage capacity automatically scales up or down when you add or remove files. NAS provides integrated data sources for workloads and applications that run on multiple ECS instances or servers.
- 3. Benefits Low costs • An NAS file system can be mounted on multiple compute nodes at the same time while still allowing access from these nodes. This reduces a large number of data copies and synchronization costs. • The performance of an NAS file system increases with storage capacity. This eliminates the need for upfront investment in high- end file storage devices and reduces hardware costs. • NAS allows you to pay only for the storage space that you consume without the need to configure storage in advance. No minimum consumption or extra configuration cost exists. For more information . • NAS features high availability, which allows you to reduce a large number of data security risks and maintenance costs.
- 4. • Ease of use You can create a file system by a few clicks without the need to deploy and maintain the file system. • Security NAS provides access control based on Resource Access Management (RAM), and access isolation based on Virtual Private Cloud (VPC) networks. NAS supports encryption in transit and encryption at rest to prevent data interception and tampering. • High reliability NAS provides multiple replicas for each piece of data that is stored in a file system. These replicas reside in devices that are isolated across different fault domains for geo-redundancy. NAS provides data reliability of 99.999999999% (eleven nines). This reduces a large number of data security risks. • High Performance NAS provides a distributed file system whose performance scales linearly with capacity. Compared with traditional data storage solutions, NAS provides a high level of storage performance. Benefits
- 5. • Compatibility NAS supports standard protocols, such as NFS and SMB. NAS provides data consistency and file locking based on POSIX file APIs. After the contents of a file are changed in an NAS file system, you can view the result in real time. Benefits
- 6. Application scenarios for NAS, OSS, and EBS
- 7. Apsara File Storage NAS provides simple, scalable, elastic, and shared file storage. You can combine this service with Elastic Compute Service (ECS) to construct your business system. You need to consider multiple factors when you deploy your applications and choose among Apsara File Storage NAS, OSS, and EBS for your applications. To help you make an informed selection, the following describes the differences between the three services.
- 8. Differences between Apsara File Storage NAS and OSS The major difference between Apsara File Storage NAS and OSS is that you can access an Apsara File Storage NAS file system in the same way as you access a local file system without modifying an application. Apsara File Storage NAS provides high throughput and high IOPS, and supports random read/write operations and online modification of files. Compared with the directory tree hierarchy of Apsara File Storage NAS, OSS adopts a different storage structure where objects are stored in flat files and are accessed through RESTful APIs. OSS does not support random read/write operations. It is mainly applicable to the upload, download, and distribution of massive volumes of data over the Internet.
- 9. Differences between Apsara File Storage NAS and EBS The major difference between Apsara File Storage NAS and EBS is that Apsara File Storage NAS provides high throughput and supports simultaneous access by thousands of ECS instances. EBS devices are bare disks. After an EBS device is attached to an ECS instance, you must format the file system of the device into a file system such as ext3, ext4, or NTFS before accessing the files stored on the device. EBS is applicable to I/O-intensive applications that require high performance and low latency, such as Online Transactional Processing (OLTP) and NoSQL databases. However, the storage capacity of an EBS device is 32 TB and is unscalable. It must work with cluster management software such as Oracle Real Application Clusters (Oracle RAC) and Windows Server Failover Clustering (WSFC) to provide shared access. Therefore, each EBS device usually provides high-performance and low- latency storage service for only one ECS instance.
- 11. FEATURES Apsara File Storage NAS provides a wide variety of features, such as scalable capacity, shared access, support for several standard protocols, security and compliance, encryption, flexible access modes, data transmission, and data backup. NAS allows you to mount file systems on various compute nodes. These compute nodes include Elastic Compute Service (ECS) instances, ECS Bare Metal Instance instances, E-HPC nodes, and Alibaba Cloud Container Service for Kubernetes (ACK) nodes. After you enable communication between different virtual private clouds (VPCs) and regions, you can mount file systems on compute nodes across VPCs or regions.
- 12. FEATURES Scalable capacity NAS provides scalable file systems. You can add file systems to increase the storage capacity, or delete file systems to decrease the storage capacity. Shared access NAS allows shared access to the same data source in a file system from multiple compute nodes and uses file locks to ensure data consistency.
- 13. FEATURES Protocol compatibility NAS Supports standard protocols, such as NFS (NFSv3.0 and NFSv4.0) and SMB (SMB 2.1 and SMB 3.0). NAS also supports mainstream operating systems, such as Linux and Windows. Access control and compliance Based on Resource Access Management (RAM) authentication, NAS provides VPC-based isolation and security group-based access control to ensure data security. Data backup NAS generates multiple replicas for data based on flexible backup policies. These replicas are used to restore corrupted data.
- 14. FEATURES Data encryption NAS provides data encryption to prevent user data from being intercepted or sniffed during data transmission. Flexible access modes NAS allows you to access file systems from various networks, such as VPCs, on-premises IDCs, and dedicated networks. Data transmission NAS supports synchronous or asynchronous data transmission between NAS file systems or between NAS and Object Storage Service (OSS) by using Data Transmission Service (DTS).
- 15. SCENARIOS
- 16. Enterprise applications NAS provides high scalability, elasticity, availability, and persistence. You can use NAS as storage solutions for your enterprise applications and applications delivered as services (ADaaS). NAS provides standard file system interfaces and semantics. NAS allows you to migrate your enterprise applications to Alibaba Cloud or construct new applications.
- 17. Media and entertainment workflows You can use NAS to share and process large files in media workflows, such as video editing, audio and video production, broadcast processing, and audio design and rendering. NAS provides powerful data consistency models, high throughput, and shared access to files. This reduces the time required to complete the preceding workflows and merges multiple on- premises file repositories into a single repository that can be accessed by all users.
- 18. Big data analysis NAS provides high throughput of computing nodes, read and write consistency, and low latency, to meet the scale and performance requirements of big data applications. You can use NAS for analysis workloads that require data interactions by using file interfaces, file locks based on file semantics, and write operations on files.
- 19. Content management and web services NAS provides high persistence and high throughput. Content management systems and web servers can use NAS to store and provide data for websites, online publishing applications, and archiving applications.
- 20. Container storage You can use containers to build microservices because containers support fast pre- configuration and flexible resource allocation, and can isolate processes. If some containers must access raw data each time they are started, you must create a shared file system for the containers. This way, the containers can access the file system regardless of the instance on which they run.
