The Internet has constructed a virtual network world. It has connected people all over the world together, formed a global village, and profoundly changed people's lifestyles.
The vision of cloud computing is to provide services to users all over the world. To realize this vision, it is necessary to provide external services through the Internet.
But the Internet is more like a black box in many cases, full of uncertainty.
Nowadays, many key financial and government applications and services have been on the cloud and provide certain and reliable services to the outside world through the Internet. This is a miracle in itself. There must be many hidden secrets behind this. Engineers in the field of cloud computing have made a lot of efforts to gradually make the originally uncertain and unreliable Internet gradually certain and reliable.
Data packet loss on the Internet is very common. Why does the Internet lose packets? Because of the congestion of the Internet link. In the real world, road congestion can make cars lied down. On the Internet, after the link is congested, data packets are directly discarded, as if they have fallen into a black hole.
The great thing about the Internet is that we only need to throw the data packet to it, and it will automatically send the data packet to the destination through its routing and forwarding strategy.
However, by default, the Internet cannot tell users in real-time the best route from one place to a place, what is the second-best route, how much time is spent, and how much money is spent on the Internet like an online map.
The uncertainty of the network path causes the fluctuation and uncertainty of the forwarding delay, which will have a relatively large negative impact on the experience of upper-layer applications.
The Internet is an open environment. In this environment, in addition to normal users and businesses that abide by laws and regulations, there is also a black-gray industry chain that exploits loopholes.
The most common method for the black and gray industry is to use DDOS attacks to make users' businesses unable to provide services to the outside world, thereby achieving the purpose of extorting ransom or obtaining illegal gains.
We know that the interconnection links between operators in the same area and the interconnection links between multinational operators are prone to congestion and packet loss.
Then we can make the traffic from cloud computing to the end-user use different operators as little as possible, and reduce the number of hops in the entire path as much as possible.
To build a more secure network environment, the cloud computing security team has accumulated a lot of offensive and defensive experience. Establish a secure network environment on the cloud, provide security capabilities to users on the cloud in a service-oriented manner, and use cloud cleaning networks around the world to disperse and disrupt the flood of attacks. At the same time, through the unique collaborative defense and threat intelligence sharing of cloud computing, with the blessing of AI technology, it can automatically and efficiently complete second-level automatic disposal and defense.
One of the most powerful aspects of cloud computing is to make the unreliable Internet as reliable as possible through resource construction and technical means so that upper-level applications and businesses can develop rapidly and vigorously.
Explore Alibaba Cloud's expanding range of high-performance cloud products including large-scale computing, storage resources, and Big Data processing capabilities for users around the world.
Alibaba Cloud Elastic Compute Service (ECS) provides fast memory and the latest Intel CPUs to help you to power your cloud applications and achieve faster results with low latency.
Cloud computing is the delivery of on-demand computing resources (including servers, databases, storage, platforms, infrastructure, applications, etc.) over the Internet. Cloud computing can be used on a pay-as-you-go basis, which means you pay just for what you need.
With cloud computing, the entire IT infrastructure, which includes both hardware and software, is stored online. Some of the most popular applications for cloud computing include Gmail, Facebook, Alibaba, Amazon, etc. To access the remote servers where data and applications are hosted, you need an internet connection.
In most cases, cloud computing services are available anywhere and only require authentication to access servers or software data. Because of the centralized access of data and resources and the flexible pay-per-use model, it has become a favored choice for businesses of all sizes. Let's look at the cloud computing models in today's market before we dive further into the history of cloud computing.
Cloud computing is still in its infancy. While it is reshaping the business and technology world every day, it is also reshaping itself constantly to meet the needs of different customers. From deployment model to location coverage and operation model, cloud computing has never stopped evolving since its inception.
But no matter how far and wide the cloud extends itself, or how flexible and diversified its deployment and operation model will be, there is one principle that should be followed - CONSISTENCY. A consistent experience, backed by a consistent technology stack. This is exactly how Alibaba Cloud, as one of the most active innovators in the space, evolved its cloud offerings in the last ten years.
This half-day online conference will help retail and e-commerce leaders to better address new challenges presented in the digital era under different business scenarios. You can also have a live chat with our experts to benefit from our leading technologies that fuel Alibaba's e-commerce business.
