With more than 1 million enterprise users across multiple industries, Alibaba Cloud is constantly aiming to better serve our customers by connecting resources in various regions through networking technologies. Adhering to the aim of "making the network simpler", after years of R&D and design, Alibaba Cloud network has made great achievements and has one of the most abundant network products in the industry. Based on different application scenarios, these products can be roughly divided into four categories, as follows:
After nine years of development, Alibaba Cloud services have spread all over the world. More than 150 kinds of cloud products are available, which are very abundant, involving basic computing, storage, network, security, big data, and artificial intelligence. At the time of writing, the infrastructure is distributed across 52 data centers in 19 regions on 5 continents, including China, UK, France, USA, Singapore, Dubai, and other major regions.
Smart Access Gateway (SmartAG) is a one-stop cloud access solution provided by Alibaba Cloud. This allows enterprises to access the nearest cloud resources through the Internet in encrypted mode, and enables a more intelligent, reliable, and secure cloud access experience.
The Smart Access Gateway mainly consists of three components: Smart Access Gateway devices, Smart Access Gateway instances, and CCN. The Smart Access Gateway provides a hardware gateway device for offline branch to access. A gateway device can be purchased by creating a Smart Access Gateway instance, and Alibaba Cloud will deliver goods according to the provided delivery address. A Smart Access Gateway instance is a logical mapping of the hardware device, which can be managed through Alibaba Cloud Console to operate the devices. Cloud Connect Network (CCN) is another important component of the Smart Access Gateway. CCN is a device access matrix composed of Alibaba Cloud distributed access gateways. The full connection between the offline access matrix and the on-cloud center matrix can be implemented by binding multiple Smart Access Gateway devices to CCN, and then binding CCN to CEN.
Alibaba Cloud Smart Access Gateway has launched 3 products in the whole series: the software client, SAG-100WM and SAG-1000. A software client is a software app suitable for mobile office and remote O&M. SAG-100WM is applicable to the branch interconnection and cloud access for small enterprises, and supports 4G and WI-FI. SAG-1000 is applicable to the branch interconnection and cloud access for large enterprises, especially the communication between local IDCs and headquarters or on-cloud data centers.
Smart Access Gateway provides a fast cloud access solution with the advantages of high intelligence, security, and reliability.
Smart Access Gateway can seamlessly achieve cloud-network integration (CNI). It connects various offline terminal devices, such as mobile phones, computers, and IDCs, to POP nodes all over the world, through distributed hardware boxes, and then the cloud and the network are integrated through CEN to implement a full interconnection network.
In actual networking, Smart Access Gateway supports two modes, which are one-arm and inline. SAG-100WM supports both one-arm and inline modes. With a simple configuration, an enterprise's branches and outlets can be quickly connected to the cloud, such as a new retail store. SAG-1000 supports one-arm mode. It requires refined network planning in combination with network settings, such as routers and switches, to enable local IDCs to be quickly connected to the cloud, such as a large shopping mall.
As a product of SD-WAN, Smart Access network has great advantages in specific scenarios. Compared with VPN and public network access, Smart Access Gateway provides superior data access quality and access speed through automatic routing of POP nodes and transmission over Alibaba Cloud backbone network. Compared with leased lines, Smart Access Gateway greatly reduces costs. It is also very convenient to deploy, monitor, and manage data in a unified manner on the cloud, which can improve the O&M efficiency and project launch speed of enterprises.
A POC test shows that the quality of data transmission based on Smart Access Gateway is far superior to that based on the public network transmission. Especially in cross-border data interaction, Smart Access Gateway can effectively guarantee the transmission speed and packet loss rate to improve the stability of data access.
With the development of the Internet, enterprises have higher requirements for data transmission, such as intelligence, security, and high reliability. Smart Access Gateway can meet the needs of enterprises based on its inherent advantages, and it has been used in various industries, such as new retail, logistics, medical treatment, online education, and chain catering.
Some businesses of an enterprise are connected to the cloud, providing services on the Internet or backing up some data to the cloud. Considering the security of the data transmission process from local to cloud, it has certain control over the cost of building a hybrid cloud. At the same time, it has certain requirements on the quality of data communication and intelligent O&M. So, Smart Access Gateway is an excellent choice for enterprises. It is out-of-the-box, has a short deployment cycle, and is free of configuration and O&M. Encrypted transmission over the Internet enables secure data transmission, quickly building a stable and reliable hybrid cloud architecture.
An enterprise has multiple offline branches or outlets, and they need to communicate with each other. In the traditional solution, leased lines/VPNs are used, which is time-consuming, labor-intensive and costly. To improve network security and deployment efficiency, and reduce the O&M costs of the enterprise, Smart Access Gateway can well meet the needs of the enterprise. Only a few Smart Access Gateway hardware boxes need to be purchased and then connected to CCN based on IPSec, to implement interconnection communication between all branches.
An enterprise has multiple offline branches or outlets, and has services on the cloud. These branches (or outlets) need to communicate with the services on the cloud. With Smart Access Gateway and CEN, a low-cost solution can be quickly built to implement a full interconnection network.
Some enterprises have extremely high requirements on the stability of data transmission. For hybrid cloud deployment, it is necessary to set up a master-slave redundancy mechanism, but it has a certain budget for the cost, and focuses on the network operation efficiency. Smart Access Gateway can provide redundant backup links. In the normal status, a leased line is preferentially selected for the link. In case of uncontrollable faults, such as broken or damaged optical cables, the Smart Access Gateway line will switch automatically to provide network communication services, thus ensuring the stability of service data transmission.
