Introduction
Cloud computing, as a popular technical medium and model in the information society, is a huge leap in technology. Users use computing resources to change the economic model in the eld of information technology, and it also promotes the development of other elds. Due to the characteristics of personalized customization of cloud computing application execution environment, more and more organizations are attracted to build high-performance computing clusters based on cloud platform technology. By using the OpenStack cloud platform to optimize the innovation and entrepreneurship education and training system in colleges and universities, it provides a rich resource and strong innovation and entrepreneurship score for college talents, which is conducive to the development of innovation and entrepreneurship education.
By integrating limited social resources through cloud computing technology, it can e ectively obtain information resources. It improves resource utilization and promotes the rapid development of the Internet and the Internet of ings. At the same time, it promotes people's understanding of the whole society and enables human society to control the material and energy of nature more precisely. It has a profound impact on economic development and social progress.
rough the related computing of OpenStack cloud computing, the user resources are integrated, and the coupling degree is associated, which enables users to independently apply resources and reduce application costs. In order to more e ectively select innovation and entrepreneurship education for students, this paper redesigns the cloud platform teaching system. It improves the teaching system and adds a teaching evaluation system and a monitoring system. It understands the dynamics of the course in real time and mobilizes the enthusiasm for learning.

With the growth of social economy, people's lives are becoming more and more intelligent and data-based, and teaching is no exception. Nelmiawati has been researching the use of OpenStack to design a virtual machine room for cloud computing on a centralized network and has achieved some results. His tests were performed using a specific server specification and the OpenStack platform. e test results of the virtual computer room and the case study of the objectbased programming course show that the server used in the test can run the virtual computer room of 9 computers well [1]. Yan-Ting enabled users to access computing, storage, networking, and other resources from a shared, configurable pool of resources conveniently and on-demand over the network. He used the existing IT equipment resources of the university to create a cloud platform university that is more in line with the scientific research needs of the university [2]. Cloud-based technology is driving positive changes in the way organizations communicate. Radwan et al. implemented three technologies of OpenStack cloud, webRTC call, and 3D stereo effect and realized the feeling of 3D video [3]. Albert et al. used Putnam's social capital framework. To achieve the goals of his research, he used a mixed approach to determine how teaching at multiple institutions affects the social capital of teachers within the Haitian AET system. e results showed a low positive correlation between teaching and social capital across multiple institutions [4]. ese studies are instructive to a certain extent, but in some cases, the demonstrations are insufficient or inaccurate and can be further improved.
With the development of intelligence and Internet, cloud computing, which combines the application of information technology and network application, is widely used. Singh et al. proposed a mathematical model to find redundant information based on overlapping regions. He employed a combinatorial metaheuristic to achieve optimal coverage, taking the effect of overlapping regions into account in the objective function to reduce the amount of redundant information perceived by the working sensor set. Improved genetic algorithms and binary ant colony algorithms are used as metaheuristic tools to optimize multiobjective functions [5]. Awad et al. used multiobjective particle swarm optimization (MOPSO) and multiobjective ant colony optimization (MOACO) intelligent algorithms to optimize data replication selection and placement in cloud environments [6]. Yi et al. studied the scheduling and collision-free routing problems of AGVs. He gave a mathematical programming model for this problem and improved the algorithm on the basis of multiobjective programming to optimize the pheromone matrix. He compared the performance of the two methods by using the available test problems for calculations. He conducted an empirical evaluation of an improved ant colony algorithm. e results show that the improved algorithm improves the performance of the existing algorithm [7]. ese studies can analyze the relevant situation, but the specific research needs to be improved.  [8]. e OpenStack project consists of several different components that work together to complete cloud computing services. e development language used by the OpenStack project is python, and the source code of the project is released under the Apache license. e main function of the OpenStack cloud platform is to integrate various physical computer hardware resources. It provides a convenient web control panel interface for cloud platform system administrators to facilitate cloud platform resource management [9]. e OpenStack cloud platform can provide flexible and easily scalable cloud computing services for large public cloud services and small private cloud services. It simplifies the implementation of cloud computing technology and increases cloud computing. It makes the cloud computing architecture more flexible and scalable [10].

e key technologies of cloud computing mainly include computer virtualization technology, computer distributed programming and computing technology, cloud storage technology, resource management, and scheduling technology [11]. OpenStack cloud platform can also be understood as a computer operating system. It uses OpenStack cloud platform users to manage all computing service resources, network service resources, and storage service resources in the cloud platform through the control panel component of the Internet Web service interface. e role of OpenStack cloud platform in cloud computing software and hardware architecture is similar to that of a physical computer operating system, as shown in Figure 1.
Cloud computing is the product of the integration of traditional computer technology and network technology, and it is also a key strategic technology and means to lead the innovation of the information industry in the future [12]. In the classification of OpenStack, this paper only makes approximately linear resource allocation according to the allocation requirements of CPU, memory, storage, and other resources, but does not consider the differentiated requirements of different virtual machines for different resources [13]. In a heterogeneous environment, different physical servers have different performances, and some CPUs have strong computing power. However, disk IO performance and network bandwidth are reduced, and some servers have outstanding disk IO performance. However, the computing power is weak, and some servers have weak overall performance but have large network bandwidth [14]. Similarly, for users, each user has different requirements for various resources. erefore, it can meet the needs of different users by dividing into a variety of different service types. At the same time, for di erent service types of virtual machines, this paper sets up virtual machine template images that focus on services. As users have more and more personalized requirements, users can also customize various requirements. e virtual machine needs to carry more network applications and occupies a large amount of network bandwidth. For example, for a virtual machine that needs to host a streaming media server and provide services such as DNS or CDN, the bandwidth will become the bottleneck of its performance. e main resource requirements of virtual machines for network tra c-based services are network bandwidth. e quanti cation of various resources is shown in Table 1.
A collection of virtual machines: e resource status of physical machine n can be expressed as RM n RCN n , RMN n , RDN n , RIN n , RNN n .
(2) e resource status of virtual machine m can be expressed as e main objectives of virtual machines are infrastructure virtualization, system virtualization, and virtual server virtualization in cloud computing. It simpli es the access and management of IT resources for cloud users through certain computer technologies [15]. In addition, for virtual machines of di erent service types, the resources of virtual machine m can be represented as service resources and auxiliary resources [16]. Service resources refer to the resources that are mainly required by the corresponding service type, and auxiliary resources refer to other resources other than the main requirements resources of the corresponding service type. erefore, the resources of various e virtual machine m of the data IO type service: Virtual machine m for network traffic type service:

Virtual Machine of the Multiobjective Ant Colony Improved Algorithm.
e initial deployment of virtual machines is to optimize power consumption, cloud platform load balancing, user SLA violation rate, and other multidimensional goals to achieve optimal deployment of virtual machines under the constraints of physical machine bandwidth, disk storage, CPU, and memory [17]. e initial deployment of virtual machines on cloud platforms can be simplified as a multidimensional packing problem, that is, virtual machines are optimally deployed to physical machines under multiple optimization objectives and constraints. e improved multiobjective optimal deployment strategy based on the ant colony algorithm can avoid the waste of system resources and improve the overall performance of the system.
An optimized virtual machine initialization deployment strategy is indispensable for improving the stability and load balancing of the entire platform. is chapter proposes an improved multiobjective optimal deployment strategy based on the ant colony algorithm for the initial deployment of virtual machines. Ant colony algorithm is a biological intelligence heuristic algorithm. e abstract method of virtualizing computer resources can access the abstracted resources in the same way as before the abstracted resources through the virtualization technology.
Ant colony algorithm simulates the process of real-world ants searching for food. In the initial case, the ants do not have any information on the food destination [18]. In the process of finding food, ants hide a pheromone on the way to find food. Because this chemical evaporates slowly, the pheromone concentration in part indicates the distance of the journey to find food. When other ants find the pheromone, they head towards their destination. Ants take a different route. If a shorter route appears, then the concentration of the pheromone is greater for that route. More and more ants will be attracted to the new route. Eventually, most ants will focus on the shortest route. is will find the optimal path. If the route is shorter from the food, the concentration of pheromones on the route will be higher, and more and more ants will be attracted to join the route. So, in this way, the ant colony finds the shortest path to the food location. A multiobjective ant colony optimization algorithm is used to find the best data replica placement based on the minimum distance, the number of data transfers, and the availability of data replication. Constraint 1 (SLA violation rate). For the problem of resource scheduling on the cloud platform, when the virtual machine created by it allocates physical machines, it must ensure the user service quality before further optimization of the cloud platform resource scheduling algorithm can be processed.
e SLA contains the indicators of multiple services to ensure the service quality of cloud computing service providers. e CPU utilization function of the server node replaces the violation rate as a universal criterion. en, the SLA violation rate function is defined as follows: Constraint 2 (resource balance). Since the resources of each physical server are not the same, and different types of virtual machines have different requirements for different resource types [19]. e amount of physical machine resources remaining on each physical machine is determined by the placement scheme of different virtual machines. However, in order to avoid the barrel effect, the resource usage on each physical node in the cloud platform should be kept as balanced as possible, such as network bandwidth, disk, CPU, memory, and other resources. It is to prevent the shortage of any one of the resources and cause the waste of other resources. Resource scheduling refers to the process of adjusting resources among different resource users according to certain resource usage rules under a specific resource environment. e utilization rate of four kinds of resources including physical node network bandwidth, disk, CPU, and memory is studied separately.
u cpu , u mem , u bw , and u disk represents the utilization of server CPU, memory, network bandwidth, and disk. u represents the arithmetic mean of CPU, memory, network bandwidth, and disk four-dimensional resource utilization. f load i represents the deviation of the four resource utilizations of disk storage, network bandwidth, memory, and CPU from the average utilization [20].
Constraint 3 (power loss efficiency). It is the total amount of power consumed by the server while it is running [21]. Under normal circumstances, the power consumed by the CPU accounts for the main part of the energy consumption of a server. A large number of research results show that there is a linear correlation between the power consumption of a physical node and the CPU usage on the physical node.
In other words, the power consumption of a physical node increases as the CPU usage on the server node increases. e relationship between the power consumption of a physical server node and the CPU usage on it.
where P busy j and P idle j represent the power usage of server j under full and no-load conditions, respectively. U cpu j represents the CPU utilization on physical node j [22]. Next, this paper analyzes the optimization problem of virtual machine initialization deployment. If the user applies to create m virtual machines, the cloud platform needs to deploy these virtual machines to n physical machines. In order to simplify the problem, it needs to add some constraints. When the utilization rate of one of the above four resources is zero, f load i takes the minimum value of 1/4, which indicates that the resource utilization rate of the entire cloud platform system is very unbalanced.
By default, the OpenStack cloud platform only performs weight calculation based on the remaining memory size of the physical node.
at is to say, the more the memory remaining on the physical host, the greater the probability of being selected as the destination host for initial deployment of the virtual machine. rough this algorithm, the resource scheduling strategy aiming at reducing the cost is used to improve the resource utilization rate. It reduces the energy consumption cost of cloud computing and improves the operation efficiency of the cloud platform.

Design of OpenStack Ubiquitous Learning Environment University Innovation and Entrepreneurship Education and
Training System Design. Innovation and entrepreneurship education focuses on cultivating students' innovative spirit and entrepreneurial quality and attaches great importance to the cultivation of students' innovative spirit and practical ability [23]. Entrepreneurship can be divided into broad and narrow senses. Entrepreneurship in the broad sense refers to pioneering and innovative activities. In a narrow sense, entrepreneurship refers to entrepreneurs looking for business opportunities and establishing some active organizations. It uses limited resources to provide certain products and services and ultimately create value. To crack the next entrepreneurship through the innovation and entrepreneurship education and training system in colleges and universities, the main body of college students' innovation is college students. It is a person who has received higher education, the object is a variety of limited resources, and its superior resources are rich in knowledge and information.
With the continuous development of entrepreneurship education, many people have begun to carry out entrepreneurship education, but they still do not pay enough attention to it. e problems of the entrepreneurship education system have gradually become prominent: the goal of entrepreneurship education is vague, the utilitarian tendency is clear, and it does not combine the characteristics of students and their own reality. Entrepreneurship education curriculum system is imperfect, lacking in quantity and weak in structure. e number of teachers is insufficient, the quality is uneven, and the degree of specialization is relatively low. Entrepreneurship education guarantee mechanism is not perfect, and teaching and management systems are not perfect and other factors. If they want to achieve their own sustainable development, they must have a comprehensive and systematic understanding of entrepreneurship education. It makes full use of its own advantages to build a sound entrepreneurship education system. e ubiquitous learning platform is a comprehensive learning platform that provides teachers and students with learning, teaching, resource sharing, and mutual assistance [24]. e goal of entrepreneurship education in colleges and universities is to achieve the goal of entrepreneurship education, and entrepreneurship education is the basis for the formulation of teaching goals and teaching content. It is a measure of teaching effectiveness. It is beneficial to enhance students' innovative ability, practical ability, social adaptability, and lifelong learning ability and realize their own sustainable development. ere are four main scenarios: (1) Learning: teachers can plan courses, create new courses, upload course materials, etc., on the platform. After logging in to the ubiquitous learning platform, students can view and find the courses offered on the platform and their related information, register courses, and study courses [25]. Students can view test scores and specific correction results to summarize their learning deficiencies. By taking exams, completing assignments, or helping grade other student work, students better understand course content, review lessons, and expedite feedback on assignments. Students can also download learning materials and then can view learning resources offline anytime, anywhere, which has great advantages over traditional teaching and satisfies the theory of ubiquitous learning. (2) Learning verification: allowing professors to verify student progress, test results, course grades, and course statistics, as well as the year's final test, organizing exams, and assigning homework. Based on these statistical observations, professors cannot justify any skepticism and make no progress, so alumni may be able to learn with mixed results.

Scientific Programming
(3) Feedback: students can give feedback on the course after the course, or they can write their own learning experience and experience in the forum. At the same time, it can evaluate and score teachers, course content, learning experience, etc. (4) Communication: when there are doubts in the learning process, students can communicate with teachers or other students and ask questions. It can also answer questions asked by others. Students and teachers can exchange knowledge with each other through discussions in the forum, and students can share materials with each other. e system application scenario is shown in Figure 2.
Platform administrators need to review teachers' registration information and manage permissions for other roles. e administrator needs to login to a separate page to set the global functions of the system, manage the system con guration, maintain the database, and monitor the operation of the system. Figure 3 demonstrates the system functions of the open source ubiquitous learning environment. User login means that users can login to the system through their user name or e-mail address and password after completing the registration. Teachers can designate other students or manually select some students to correct their assignments, and they can also view historical assignments and correction records. Teaching material management: teachers can upload and download corresponding teaching materials and set the use rights of teaching materials, etc. [26]. e speci c evaluation process of the homework evaluation subsystem and the ubiquitous learning system is shown in Table 2. When students submit homework in the homework evaluation subsystem, the homework also needs to include the address to be sent back after correction. e address can be assigned automatically by the system or manually by the teacher. Students receive assignments and grade them and return the work when they are done, with an item in the work indicating the grade of the work. It checks whether the job obtained is a job that has been judged and speci es whether it needs to be modi ed or needs to be displayed according to the judgment situation. e data table of the homework evaluation subsystem is shown in Table 3. e relevant data items are explained in the above two data tables. After a student passes the online test, the system obtains the student's test result data and stores it in the score database. After the corresponding functional function processing, the student progress monitoring system can view the relevant learning data of the students according to di erent needs.

large virtual computing clusters. e test of the simulation experiment is run on the NUDTSCI Cloud scienti c cloud platform composed of 2 cloud hosts and the physical highperformance cluster composed of 2 nodes. Table 4 describes the con guration of physical nodes and cloud hosts.
In the experiment, 6 applications that are relatively representative in the test set are selected: (1) integer sorting (IS); (2) complex parallelism (EP); (3) multigrid benchmark (MG); (4) conjugate gradient formula solving; (5) block sparse formula solving (LU); (6) fast Fourier transform (FT).   Scienti c Programming e test results of NPB are expressed in millions of oatingpoint operations performed per second, which can show the actual performance of general application programs. 4-Core and 8-core parallelism were started on a single node of 2 cloud computing, 4 physical clusters and high-performance computing cloud platform, respectively, and the running time of each test program in the NPB test set was recorded. ey form a parallel virtual set of 16 CPUs and 32 CPU cores, respectively. It records the running time of each test program in the two clusters in the NPB test set as shown in Figure 4.
It can be seen from the experimental results that when the virtual machine exclusively occupies the physical node, the running time of the six test programs in the NPB test set is not much di erent between the physical node and the virtual machine. Among them, the FT program with the largest di erence increased the running time by about 8.5% on the cloud platform after the introduction of virtualization overhead. It can be seen from this that, whether it is the performance of oating point and integer operations or the communication performance of sets, the extra overhead after the introduction of virtualization is within 10%.
Due to the lack of analysis of OpenStack's built-in algorithm, this paper elaborates the proposed multiobjective optimization algorithm based on the ant colony algorithm in detail. Due to the limitations of the laboratory environment, it cannot meet the requirements of the experiment. erefore, we choose to simulate the algorithm on the mainstream cloud simulation platform CloudSim to verify the e ectiveness of the algorithm proposed in this chapter. In order to comprehensively test the performance di erences between high-performance cloud platforms and physical clusters, this paper designs the following experiments from di erent aspects. Start two virtual machines on each physical node and set the parameters as shown in Table 5.
It is the percentage of incidents resolved within the agreed SLA time, which checks the performance of the IT service desk against the service level agreement with the user. e comparison of user SLA violation rate, power consumption, and OpenStack virtualization test of multiobjective ant colony improvement algorithm scheduling strategy is shown in Figure 5.
It can be seen from Figure 5 that compared with the previous two groups of experiments, the virtual machine dynamic scheduling algorithm proposed with the multiobjective ant colony improved algorithm has improved about 20% in terms of power consumption and user SLA violation rate. It proves the rationality and e ectiveness of the designed virtual machine dynamic migration scheme.  Figure 4: e server starts the virtual machine to run the NPB comparison test. According to the analysis of the functional requirements of the innovation and entrepreneurship education and training system in colleges and universities, this paper focuses on testing the performance stability of each node under high system load. e test environment is o ine. is paper simulates 10 physical machines, 5 meta virtual machines, and one object storage device in a cloud data center.

Performance Test of Innovation and Entrepreneurship Education and Training System in Colleges and Universities.
is article uses MDTest to test the system IOPS of the le system, increases the pressure on the server node through open/close/stat operations on the le, and runs a large number of client programs at the same time to cause access pressure to the server. rough eight hours of uninterrupted operation, the throughput and load of the cluster are counted during this article. e simulated data center con guration table is shown in Table 6.
e ve MDSs are named as MDS1-5, respectively. Taking MDS1 as a reference, their performance ratio is 1 : 3: 17 : 1.5 : 4, the number of consecutive times is N 2, and the trigger threshold θ is set to 0.2. is article records the load  Scienti c Programming value of the load balancing strategy without and with the load balancing policy turned on, respectively. e calculation formula of the system load balancing degree is PD is the load balance degree value, and Li is the load value of node i. In the experiment, a test script was written to record the system load value, including the central processing unit and the internal storage device.
After the system runs for 8 hours, the average processor load is calculated according to the load balance calculation formula. During the 8-hour test, load data were recorded every hour. Finally, this paper calculates the processor and memory utilization. Assuming that the processor accounts for 60% of the performance and the corresponding memory accounts for 40% of the performance, the cluster pressure is gradually increased. It obtains the load of the cluster when the load balancing strategy is not enabled and enabled, respectively, as shown in Figure 6.
As can be seen from Figure 6, the load of each server is not related to a certain extent, and the load is generally high; even the utilization rate of MDS5 exceeds 80% for a period of time. is also shows that, during this period, the access performance of the node will also decrease. It can be seen that the situation without load balancing is very unstable and the load is high. It can be seen from the experimental results that the overall load has decreased and the load of each MDS is relatively close, and the system has achieved the expected expectations.

Aiming at this de ciency, this paper builds a model and sets constraints. Finally, through the simulation comparison on the cloud simulation platform, this paper veri es the e ectiveness of the algorithm in improving the load balancing of the system, reducing the violation rate of users, and reducing the power consumption of the system. rough the relevant design of innovation and entrepreneurship education courses, users can not only enjoy resources at a low cost but also reduce entrepreneurial risks.   is paper conducts an indepth research and analysis on the mechanism of OpenStack virtual machine resource scheduling through cloud computing virtual machine technology.
