This is an era of rapid development of IT technology. With the continuous upgrading of hardware infrastructure and the increasing maturity of virtual networks and other technologies, cloud manufacturers are also facing great challenges brought by a variety of new technologies. From the infrastructure of the data center to the system construction of the cloud platform to the technological reform at the bottom of the product, how to combine the latest technology trends and the ever-changing needs of users in order to achieve further development? on December 21st, the UCloud user meeting and the "Product and Technology Special session" of Think in Cloud 2018 Shanghai Station will share UCloud's thoughts on these issues.

Minimalist product, very deep technology

We know that Jobs has been pursuing minimalism all his life, which emphasizes the extreme in simple product design, but it often requires a comprehensive understanding and in-depth exploration of the needs of users. In this regard, UCloud has always adhered to the belief that "users' needs are the next product". While meeting users' business needs, UCloud continues to polish the shape of the products until it presents users with simple, direct, easy-to-use, stable and highly available cloud services. For example, after continuous upgrading and optimization, the performance of ULB has been greatly improved, while a variety of equalization algorithms and automatic disaster recovery have been achieved, while the user interface is becoming more and more simple, which makes it convenient for users to make intelligent choices, thus improving resource utilization. In addition to ULB, UCloud has many such product design cases.

If an enterprise wants to always be at the forefront of the industry, it must master its own core technology and improve technical barriers. With the development of nearly 6 years, UCloud keeps pace with new technologies to speed up the iteration of new products and features: 1000 CVMs can be created concurrently in 5 minutes, hot patches of CVM kernel are moved online, and the ultra-high performance of SSD cloud disk is improved by 13 times, and so on. When the functional features of cloud computing products are becoming more and more similar, how can competitive cloud manufacturers create their own differentiated technological advantages? What technology is used to realize the minimalist design concept of these new product features?

Next generation network

For the UCloud product line, virtual network has always been a core component of IaaS products, and it has evolved many times. In the evolution, we always think about how to provide users with a more reliable and faster network without increasing the cost of users. The answer is to require the technical team to constantly adopt new technologies to meet the needs of new features, forwarding capabilities, stability and so on.

Since the beginning of 1990, the fourth generation Internet (IPv4) has experienced rapid development by virtue of several waves of the Internet. Now the restrictive problems such as IPv4 resources are almost exhausted and the quality of service is difficult to guarantee. The sixth generation Internet (IPv6) is gradually approaching the vision of the public. UCloud has also begun to switch the IPv6 of some products on the cloud platform. In this process, because IPv6 and IPv4 are not directly compatible, how to ensure that the old services running on IPv4 and the new services switching to IPv6 network can be connected? How to realize the evolution from IPv4 to IPv6 in the network environment on the cloud platform?

With the increasing demand of users for the improvement of network performance, 25G network card has gradually become a standard configuration. In order to meet the network performance in peak traffic scenarios such as holiday promotion, UCloud research compared the mainstream intelligent network card schemes in the industry, and finally adopted the self-developed new intelligent network card scheme to be applied to the CVM, which can increase the network capacity by 4 times and reduce the latency by 3 times. How did the new intelligent network card scheme fall to the ground? Which holes did UCloud step on and how did he break them one by one through technical means?

In addition to the new intelligent network card scheme, 25G network also poses many challenges to the virtual switch of UCloud. From the original SDN switch to the gateway cluster using DPDK technology, there are still many problems. Through continuous pre-research and testing, the UCloud network team has developed a new generation of switching gateway UXR by using Barefoot's P4 programmable switch. What is the advantage of P4 compared with other switch schemes? What is the principle of realization?

Next generation computing

In recent years, the emergence of container technology and Serverless computing is reshaping the pattern of next-generation computing. Some people say that Serverless will become the mainstream of the cloud computing industry, even surpassing container technology. However, with the rapid development of container orchestration technology represented by Kubernetes, some people think that containers are the future of cloud computing.

Kubernetes is designed to provide developers with a clean, application-oriented API that makes them forget the details of underlying server management. The advent of Serverless allows developers to completely ignore these underlying servers. Since the successful use of Serverless for large-scale applications requires the development of choreography systems, the integration of Kubernetes orchestration layer and Serverless may be an indispensable core technology for the next generation of computing.

UCloud has been promoting research and development at the application level of container technology since 2015. In terms of availability and resource utilization, container technology is lighter and easier to achieve dynamic migration and setup than traditional virtualization technology, especially in hybrid cloud deployment. In addition, container technology has also been used on UAI-Train (UCloud AI training platform). It is essentially a PaaS service, which can automatically create a running environment (Docker container) for training tasks. UCloud has also developed a Kubernetes-based computing resource delivery platform. So how on earth are these products modified with new technology? What other applications are there about Kubernetes container technology?

What are the problems to be solved in global infrastructure construction?

With the gradual disappearance of the user dividend monopolized by the giants in the domestic Internet application market, coupled with the stricter regulatory system and the national "Belt and Road Initiative" initiative and other factors, more and more Internet companies begin to go abroad to seek overseas user markets. In order to help more enterprises lower the threshold of business "going out to sea", UCloud has successfully landed in many localized regions around the world, including Nigeria, Thailand, Brazil, India, Russia and so on.

UCloud has accumulated rich experience in the construction of data centers to help more enterprises "go to sea". From the basic information of data centers to reliability design, carrying capacity, bandwidth quality, supporting monitoring facilities and other aspects, consideration can no longer become the absolute factor of users' choice. So, in the face of increasingly diversified and global business, what other aspects need to be fully considered in the construction of the data center?

It has been proved that users often give priority to local coverage with low latency. In addition to local access, the delay of global access should also be considered, and the ability to resist DDoS*** on a large scale cannot be ignored. Finally, if the business encounters changes, how to ensure real-time expansion to achieve seamless upgrade? Can the new generation of data centers solve these problems from users themselves?

The above mysteries will be revealed at the UCloud user conference and the special technical show of Think in Cloud 2018 Shanghai Railway Station on December 21st. At that time, Yang Ra, vice president of UCloud, will bring an in-depth analysis of cutting-edge technology topics such as the design concept of minimalist products, next-generation networks, next-generation computing and global infrastructure construction. In addition, it will also share the new generation of UCloud background system and Service Mesh network grayscale and other content.
