Four Stages of Cloud Adoption

Alibaba Cloud has been working hard for the slogan "more than just cloud" by breaking down barriers of emerging technologies and redefining the digital world. Throughout Alibaba services, the whole development process of Alibaba service can be roughly divided into four stages.

Stage One: Migrating IT system on cloud. The initial products of Alibaba Cloud are to provide flexible and scalable cloud servers for enterprises through hybrid cloud with existing IT architecture. Thus, realizing the migration of IT systems in the cloud, the results of this phase meet the enterprise pursuit of cloud services. Many enterprises purchase servers and deploy non-core enterprise applications on Alibaba Cloud.

Stage Two: Deploying core business on global cloud. After the first step of service cloud, Alibaba Cloud strives to provide customers with more global cloud services. Nowadays, many regions have been deployed in China and even in the world, and then these IT resources have been utilized to realize the global public cloud and the global service strategic deployment of itself and its customers. At this stage, more companies are willing to deploy enterprise productivity or office applications on the cloud.

Stage Three: Microservices on cloud. With more and more applications coming to the cloud, deploying cloud servers is cumbersome. Alibaba Cloud provides customers with better cloud Microservices so that enterprises do not have to worry about complicated server operations and maintenance work, but focus on the purchase of Microservices they need and improve the enterprise in the cloud office efficiency.

Stage Four: Intelligent Cloud. With the advent of the era of big data, Alibaba Cloud is also embracing the challenge. Give full play to the advantages of many years of experience and provide customers with intelligent learning and large data service based on IoT so that they can promote visits through Big Data or AI.

Three Stages of Cloud Network Adoption

The continuous progress of cloud service is inseparable from the continuous development of network solutions. The development of Alibaba Cloud network solutions can also be roughly divided into three stages.

Stage One: Internet access to cloud. The early solutions combined the virtual machine's network with the physical network to form a flat network architecture, such as the large layer two network. With the increase of virtual network scalability, problems are getting more serious for the early solutions. These problems include ARP's proofing, broadcast storms, host scanning and more. Various network isolation technologies emerged to solve these problems by completely isolating the physical networks from the virtual networks.

One technology isolates user with VLAN, but VLAN only supports up to 4,096 nodes. It cannot support the huge number of users in the cloud.

Stage Two: Private Hybrid Cloud. With the continuous development of cloud computing, virtual network requirements are getting higher and higher, such as scalability, security, reliability, privacy and higher requirements of connection performance.

This gives a rise to a variety of network virtualization technologies. With the tunneling technology, Alibaba Cloud has developed V-Switch, Software-Defined Network (SDN) and Hardware Gateway, and thus created VPC.

V-Switches are distributed the nodes. The gateway and the controller are deployed in clusters, and all links have redundant disaster recovery. This improves the overall availability of the VPC.

Stage Three: Global Cloud Network. In order to meet the needs of a global deployment, Alibaba Cloud provides Cloud Enterprise Network (CEN) and Global Accelerator (GA) and other services to provide users with a high-quality, efficient and stable network transmission environment. Cloud Enterprise Network (CEN) will provide a global network that can quickly build hybrid cloud and distribute business systems to help users build a cloud and network with enterprise skills and communication capabilities. Alibaba Cloud networking services provide you a highly stable, low latency and high-speed network with flexible hybrid cloud connections. Alibaba Cloud networking services deliver secure and reliable communication to and from RDCs in 19 regions globally.

Global Coverage

With more than 65 availability zones globally, Alibaba Cloud's large node network gives you access to close by nodes-shortening geographic distances. Alibaba Cloud has the following advantages in network service solutions – Cross-Region Global Network Connection. Alibaba Cloud provides fast and cost-effective networking services for multinational enterprises to build cross-region network connections.

Alibaba Cloud provides you with an easy-to-use interface to manage your networking services, such as Cloud Enterprise Network (CEN). You can set up a multi-region networking environment in four steps within five minutes.


To sum up, selecting Alibaba Cloud service is to select the best quality and reliable service.

Let's have a look at Alibaba Cloud network services portfolios. Alibaba Cloud network technology system is divided into three parts -- Cloud Network, Interconnected Cloud Network and Connect-to-Cloud Network.

Cloud Network provides rich network functions on Alibaba Cloud and the management of access to public network traffic. These functions include Elastic IP (EIP), NAT Gateway, Virtual Private Cloud, VPC and Server Load Balancer (SLB).

Interconnected Cloud Network is responsible for the network connection between VPCs, mini-level construction of a cloud across 19 regions in Alibaba Cloud. The Interconnected Cloud Network includes Cloud Enterprise Network (CEN) and Global Accelerator (GA).

Connect-to-Cloud Network is a safe way for users to go to the cloud. It connects the POP points, distributed all over the world to the VPC channels on the cloud, and realizes the communication between the POP points. The Connect-to-Cloud Network includes the following services -- VPN Gateway, Express Connect and Smart Access Gateway.
