In the past one or two years, enterprise-level PaaS platforms have emerged one after another, and products on the market have sprung up. Applications supported by different cloud platforms have different characteristics. Some of these reasons come from the business itself, but also from different institutions, such as enterprises, banks and governments, as well as different privacy needs and performance requirements. In the future, PaaS in the vertical field will have more opportunities. Back in history, as early as 2012, many SaaS and IaaS vendors began to push PaaS platform services, such as UFIDA PaaS platform, Puyuan PaaS platform, Sina SAE's IaaS PaaS model. At that time, the mainstream PaaS platform was divided into two types. One is represented by the US Heroku and the domestic Sina SAE. Its purpose is to solve the problem of the mobile background, so it is called AppEngine. However, this PaaS application scenario is less, only supporting the mobile terminal. The other is Cloud Foundry, which is designed to be a large and comprehensive PaaS platform that solves all the problems encountered during the production process. However, the object is extremely reversed. The too heavy design makes it difficult to use, configure and maintain. It is very heavy for users and solution providers, so it is not recognized by the market. Wang Yun, CEO of Digital Cloud, believes that these platforms can be attributed to the previous generation of PaaS products. Because of its rich content, it is difficult to define between IaaS and SaaS. This makes the user understand very difficult, so basically all of them are killed. In 2014, the watershed of PaaS. In the chaos, the savior Docker appeared, and the development of PaaS had hope. There is no doubt that Docker has become one of the hottest technologies around 2014. The development is a triumphant, and it has the advantages of container, virtualization, lightweight, portable and distributed, and its appearance is also in a difficult situation. The PaaS platform in China brings a glimmer of life. “Docker defines a boundary for PaaS, which allows the development and use of PaaS to be based on evidence and standards. This is clear to the platform provider for product development. Docker encapsulates various business applications. Outside of Docker is the container runtime environment provided by PaaS. In general, Docker makes PaaS out of the thick and thin. Because the container carries a variety of programming languages. PaaS only needs to provide a standard container runtime environment. Therefore, the PaaS product based on the container and Docker is defined as the standard and common PaaS platform. This has led to a new generation of claims." Wang Wei said. It’s the right time. The sudden popularity of PaaS is due to the maturity of technology and timing. In 2014, Docker gradually emerged, and its lightweight virtualization can be used to deploy and launch applications in seconds. At the same time, Docker is based on mirror layering, sharing mechanism, and Dockerfile-based image creation mechanism, which can easily package and deploy applications. It really achieves a build and runs around, and the later application is repackaged and deployed. . At the timing, the IaaS transformation of traditional enterprises has accumulated a lot of X86 and modular experience. Just like the current Internet applications, such as spikes, promotions, festivals, etc., make the application more flexible, which is in line with the application development path of micro-services, and also the stateless words and micro-services required by container-level virtualization. Make a difference. Usually cloud computing is divided into three layers, IaaS, PaaS and SaaS. IaaS can support PaaS, but PaaS is not mainly used to support SaaS. When the new generation of PaaS appeared, the original layered logic of cloud computing changed. The bottom layer was IaaS, the middle was PaaS, and the upper layer was not only SaaS, but the upper layer also included enterprise production system, because the new generation PaaS is more supportive. Enterprise production system. Therefore, for the number of people cloud, their products are more oriented to the internal production environment of the enterprise, mainly providing PaaS platform services on the private cloud. It is understood that Digital Cloud is the leading cloud computing innovation technology practitioner in China, and is committed to creating the most lightweight PaaS platform, and the application flexibility is the ultimate. Based on Docker Mesos, Digital Cloud implements a one-stop microservice architecture cluster system to maximize the rapid deployment of application services in the cloud and solve the last mile from users to cloud resources. So what is the so-called "lightweight"? For enterprises, to quickly meet the needs of the market, it is necessary to have a high level of business responsiveness. Behind this, IT is crucial. Whether the construction of IT products can meet the rapid launch, rapid iteration, whether it can meet the elastic expansion of the scale of Internet business, whether it can support business, and then lead the business, these are no small challenges for traditional enterprise information centers and CIOs. And this is the original intention of the digital cloud "lightweight PaaS". Wang Wei said: "With the rapid advancement of technology, enterprise-level IT construction has gradually changed. The original products such as J2EE and WebLogic are very heavy and difficult to maintain by themselves. Now the enterprise information construction is more self-controllable, enterprises are I hope that the internal IT environment can control the use of some Internet-based products to build applications that support business development. At the same time, with the development of the Internet and mobile Internet, the business forms of traditional enterprises such as finance and operators occur. A big change. This requires them to quickly transform and make their forms more Internet-oriented. As a basic tool to support business development and transformation, IT architecture needs to be more Internet-oriented, making it simple to deploy, easy to manage, and easy to maintain. Capability. This allows CIOs to choose some technologies and products that originate from the Internet, so that enterprises can be absolutely independent and self-sufficient in IT, just like Internet companies." Therefore, the lightweight of the Digital Cloud PaaS platform is reflected in two aspects. First of all, it can help enterprises achieve rapid iteration of IT applications, fast online, continuous delivery, continuous integration, and agile development. Secondly, it can help enterprises achieve high flexibility at the application level. With the instantaneous surge in business scale, the system can quickly adjust to support and shrink. When the traffic drops, the system can automatically reallocate computing resources. According to the survey, the IT construction of traditional enterprises does not have the capacity of “lightweightâ€. He believes that "lightweight" does not mean that the product is simple. For example, Google's internal IT is very large, but Google's IT system is very light, its PaaS application is relatively early and large, and has helped Google to support enterprise business applications for many years, and can achieve fast online, application elastic scalability. So the number of people borrowed from Google's philosophy, using open source components to make a lightweight PaaS product, which is provided to traditional enterprises, making it easier for them to cope with the needs of the Internet business. Mentioning the advantages of the "lightweight" of the number of people, the following words can be summarized: The first is second-level expansion. Enterprise application number of people cloud PaaS platform, can expand thousands of container instances in seconds, easily cope with high concurrency. The second is to mix a variety of applications. Digital Cloud has mixed Docker container applications with big data applications such as Spark in the same cluster to improve resource utilization. The third is to support a hybrid cloud environment, including public, private, and hybrid clouds, while supporting physical and virtual machines. The fourth is to deploy Spark and Hadoop distributed applications with one click. The fifth is to simplify operation and maintenance. The digital cloud PaaS uniformly monitors the usage of various applications and cluster resources, and simplifies operation and maintenance management. The last is to ensure high availability. Once you encounter problems such as downtime, you can automatically migrate application instances on the failed server to ensure high service availability. There is such a saying in Google, do you want to treat the server as a pet, or treat the server as a cow? When a pet is treated, there must be a dedicated DBA to manage the server with the database installed. Machine, the entire business will be affected. This approach is very demanding for the post-maintenance requirements of the server. At present, most of the traditional enterprises in China are of this type. People turn around the machine. If an application has a problem, it is necessary to find the corresponding server. Who is the first person in charge and who is the second person in charge. This will inevitably increase the complexity of operation and maintenance, so that the burden of operation and maintenance personnel is very heavy, and CIOs are often seen as firefighters. The other is that like a cattle farm, hundreds of cows are like server clusters. One or two cows will not affect the entire cattle farm business. Google is using this philosophy to manage the data center. "Google has two or three million servers built in. If it is pet-based, it is difficult to achieve effective management. The server in Google data center is like a cattle farm. The operation and maintenance personnel do not directly manage the server, but surround it. Application, business transfer, because business is the most important. Therefore, in the product system of the number of people, the concept of host and server has begun to fade, they allow the server to go wrong, when the number of people can automatically accept The affected applications are restored on other available servers to ensure business stability and continuity. We want to convey to users the idea of ​​letting users embrace new ways and reject traditional thick methods through lightweight PaaS and containers. Easy management and simple operation and maintenance. But now this concept is still in the incubation period. The company has also established a dual-mode drive to cope with the transition period." It is undeniable that the emergence of new things will definitely bring about two levels of positive and negative effects, as well as container technology. First of all, Docker lacks the high-level networking capabilities between containers. In a large-scale environment, this can be a problem if the container needs to contact other containers that are not on the same Docker host. At the same time, Docker provides weak isolation and security mechanisms relative to virtual machines. Docker requires root privileges to function properly, which means that there is a high probability of vandalism. As long as the password is cracked, all the containers on the host will suffer. There are also storage issues, and the storage capabilities supported by the current container environment are still limited. Based on the above considerations, Wang Wei suggested that traditional enterprises should avoid these risks as much as possible. Enterprises should try to use containers in a private cloud environment. The network should try not to use container-based SDN, or IaaS-level SDN, or physical network. Enterprises can only use load balancing as a simple network because it is verified. In addition, at the data level, enterprises should try not to manage storage-related applications without using containers, and do not install databases in containers, so as to achieve their own shortcomings. In addition, the fundamental basis for evaluating the success or failure of a platform is whether it solves the most essential and rooted needs of users. The PaaS platform has a high technical threshold, and even if it is made, it is difficult to operate and maintain on the user side. In order to achieve the initial goal, the digital cloud has been working hard in the development, testing, and landing practice of the platform. In Wang Shuo’s words, the number of people expecting to make their products more mature and mature reduce. His clear understanding, in the past few years of cloud computing, traditional enterprises have begun to gradually adapt to IaaS, with the process of going to IOE, enterprises gradually transform applications, applications gradually modularized split migration to virtual machine deployment and operation, However, application transformation is a long process, and from the application side, it has not reached the level of PaaS. In 2016, the PaaS market entered a new phase, and PaaS cloud services will move from developer-driven to enterprise demand-driven. At the same time, companies in almost all fields are seeking technological innovation and business transformation. They want enterprise IT staff not to care about the underlying hardware, operating system, middleware deployment, and network of the IT infrastructure, but only need to provide serviced middleware components through the PaaS platform, and these services and middleware components are automatically generated by the PaaS platform. Management and operation and maintenance. For the enterprise, in the process of deploying the PaaS platform, the most concerned issue is the application transformation and the operational stability of the business system. We have seen that there are many PaaS platform companies in the market that constantly combine various technologies, but ignore or close the basic needs of enterprises or industry applications. Combined with the application, the professionalism requirements of the platform providers are very high. It is necessary to be proficient in technology and familiar with the business systems of enterprises or industries, so as to guide the PaaS transformation of business software. After the transformation, the various indicators of the application have a metric compared to the previous one to ensure the success of the transformation. In addition, when the enterprise has truly completed the transformation of PaaS, for the core system, once it is applied online, operation and maintenance becomes a top priority. In addition to the operation and maintenance of the PaaS platform itself, it is necessary to display all aspects of the business system. The accumulation of several people's cloud at the business level is still lack of experience, but as a technology-driven innovation company, they are exploring the application scenarios and pain points of the financial industry, carrying a heart-shaped deployment of enterprise-class PaaS platform, a group Young people, nothing is impossible. The development of technology is advancing by leaps and bounds, but we can't admit that the new generation of PaaS has matured, but at the enterprise deployment level, the new generation PaaS platform can realize seamless migration from the development environment to the PaaS platform with Docker. From the inside out, Docker is a powerful helper. It can be said that Docker has taken root in a new generation of PaaS platform. However, PaaS is one of the service models of cloud computing, and its market scale is much smaller than that of SaaS and IaaS. However, when these two models encounter bottlenecks during the outbreak period, users and enterprises will eventually return to PaaS, and the three will complement each other. . Applications supported by different cloud platforms have different characteristics. Some of these reasons come from the business itself, but also from different institutions, such as enterprises, banks and governments, as well as different privacy needs and performance requirements. In the future, PaaS in the vertical field will have more opportunities. According to some surveys, 40% of potential enterprise users plan to deploy PaaS platform in the next year, then we can be sure that the next one to two years will become the intensive period of PaaS platform deployment, and the PaaS market will also usher in rapid development.
