teaching and research laboratory that is compatible
with the past, based on the modern, and oriented to
the future, so that today's experimental equipment and
means can adapt to the rapidly changing era and
constantly improving technology (Huang and Quan,
et al. 2019). Throughout the development process of
instruments, equipment and experimental technology,
we can use less money, less experimental system
development and maintenance costs, and less time to
achieve the experimental environment required for a
variety of experiments. Each new major needs to
build a corresponding professional laboratory. In
addition, the old professional laboratory needs to be
constantly updated and transformed, which leads to
the increasing task of professional laboratory
construction in colleges and universities, and more
and more problems need to be studied and discussed
(Yujia and Zhang, et al. 2019). Based on cloud
technology, this paper further studies the construction
of university laboratory and management system.
2 CLOUD TECHNOLOGY
THEORY
Cloud technology is a usage mode of IT resources. It
is a technology that provides ubiquitous, convenient
and on-demand network access to shared and
configurable computing resources. The use and
release of resources can be carried out quickly
without much management cost. Cloud computing is
a mode that can acquire computing resources and
improve their usability in a convenient and on-
demand way through the network. These resources
come from a shared and configurable resource pool,
and can acquire and release resources in a simple and
unattended way. At present, there are many
explanations and definitions of cloud computing in
the network. It can be understood as a commercial
product of the comprehensive development of
distributed computing, parallel processing and grid
computing. It is an abstract method to represent
computer resources. Through virtualization, the
abstract resources can be accessed in the same way as
the pre-abstract resources, thus reducing the operating
cost. High flexibility and automation, service creation,
resource allocation, service configuration, service
online and service start-up, service stop, service
offline, service configuration deletion and resource
recovery, and dynamic management of service life
cycle. A common abstract interface set can be
provided for a group of similar resources, thus hiding
the differences between attributes and operations, and
allowing resources to be viewed and maintained in a
common way, including server virtualization, storage
virtualization, application virtualization, platform
virtualization, desktop virtualization.
The primary value of cloud computing is mainly
manifested in scale expansion, resource sharing can
greatly reduce the unit cost of operation and increase
the number of users; Service sharing can reduce the
cost paid by users, bridge between users and services,
and rapidly increase the number of shared services
and resources, resulting in the multiplier effect of
economic scale. Use virtualization technology to
build virtual resource pool, shield specific hardware
architecture and diversified software system
platforms, dynamically allocate resources according
to users' needs, and monitor the allocation of
resources in real time through management software.
3 SYSTEM DESIGN
REQUIREMENTS AND MAIN
ARCHITECTURE
3.1 System Functional Architecture
Design
University laboratories are important bases for
experimental teaching, training high-level talents,
conducting scientific research and serving the society.
The specialized laboratory is an indispensable part of
the teaching process, which plays an irreplaceable
role in teaching theoretical knowledge in the
classroom. With the development of cloud computing
and virtualization technology, virtualization has been
used in various production environments. For this
reason, the laboratory is built by building a virtual
cloud platform to provide students with a learning and
research and development environment. Using cloud
computing platform to build university laboratories
can provide an ideal solution, reduce the investment
in computer software technology and hardware
equipment updating, reduce the investment in
laboratory personnel maintenance and training, save
time, and reuse abandoned equipment. The concept of
distributed storage and server virtualization is
adopted to organically integrate cloud computing
technology with the software and hardware resource
system of laboratory management in conventional
colleges and universities, and build a high-speed
cloud platform architecture for laboratory
management. Specifically, the core architecture of the
system consists of three parts, namely: infrastructure
