Description

Railway Beidou application service cloud platform based on virtualization and resource management

Technical Field

The invention relates to the technical field of virtualized resource management, in particular to a railway Beidou application service cloud platform based on virtualization and resource management.

Background

Traditional network virtualization technology cannot solve the main contradiction faced by the cloud computing era network. Taking a VLAN technology for realizing logic isolation as an example, in the deployment of a large-scale cloud network environment, two limitations exist, namely, firstly, VLAN is subjected to label isolation based on a second layer network, in a cloud computing environment with a large number of virtual machines, the virtual machines can be scheduled to any physical server in a data center network, the range of one VLAN cannot be amplified limitlessly and is configured to all access switches, secondly, in a standard protocol defined by IETF, the VLAN ID length is 12 bits, the value range is 0-4095, the available number is 4096, and in the cloud computing environment, the network isolation requirement is far more than 4096 virtual networks.

In addition, SAN and NAS devices are often used in conventional enterprise-level storage. However, with the popularity and application of cloud computing, conventional storage devices face a number of limitations, specifically as follows:

The problem of storage elasticity is that the traditional enterprise-level storage can not meet the requirements of different loads and dynamic resource changes of multiple services. Therefore, when different tenants and different applications have different demands on resources, it is difficult to make corresponding adjustment according to actual situations, such as elastic allocation of performance and capacity resources. In a cloud computing environment, the elasticity of resources under the load of multi-tenant service is an important requirement for a storage system.

The problem of storage expansion is that expansion of traditional storage equipment faces a plurality of bottlenecks, such as synchronous expansion of machine heads, front-end and back-end networks, magnetic disks and CPU/memory resources, and the like.

The problem of lack of flexible configuration policy is that under the cloud computing environment, different tenants and different services have different demands on storage services, so that storage is required to have flexible software defined policy support, and policy configuration (such as defining total capacity, IOPS, cache, reliability requirements and the like of the support) of the storage is allowed for a user as required. However, conventional storage generally adopts fixed hardware configurations, and it is difficult to meet flexible configuration requirements.

Based on the above-mentioned problems, a resource management technology that breaks through the time space limit, has higher operation capability and can realize dynamic expansion is needed to realize flexible allocation and elastic storage of resources.

TABLE 1

Virtualization is one of the key technologies necessary for building cloud infrastructure. Cloud computing cloud systems are essentially large distributed systems. More virtual platforms can be virtualized on one physical platform through virtualization, and each virtual platform can be used as an independent terminal to join a cloud distributed system. Virtualization has great advantages over direct use of physical platforms in terms of efficient utilization of resources, dynamic deployment, and high reliability. By using the virtualization technology, enterprises can build an entirely new infrastructure without discarding the existing infrastructure, thereby more fully utilizing the original IT resources.

The realization form of the computing virtualization technology is to add a virtualization layer into the system, abstract the resources of the lower layer into the resources of another form, and use the resources of the upper layer. The general implementation scheme of the computing virtualization technology is that software and hardware are separated from each other, a virtualized software layer is added between an operating system and the hardware, and physical resources of a server are abstracted into logic resources, so that an upper operating system can directly run on a virtual environment, a plurality of virtual machines with different operating systems are allowed to be isolated from each other and run on the same physical machine in parallel, and therefore higher IT resource utilization rate and flexibility are provided. Each virtual machine is a complete system with a processor, memory, network devices, storage devices, and BIOS. Operating system software running in a virtual machine is referred to as a virtual machine operating system. This software layer of computing virtualization, the virtual machine monitor, is commonly referred to as a Hypervisor.

The conventional storage needs to be configured to store special hardware, the price of the special hardware is high due to the fact that the delivery volume of the special hardware is high, the distributed software definition storage adopts a universal X86 server, the purchase and operation cost of the hardware is greatly reduced, meanwhile, based on a software definition storage architecture, the enterprise data migration speed is greatly improved, and the total ownership cost is further reduced.

In addition, stand-alone or stand-alone SANs are increasingly unable to meet the needs of large-scale data storage for enterprises in the face of extremely flexible storage and performance requirements. As with database systems, block storage of distributed storage also faces the need for lateral expansion in cases where the longitudinal expansion suffers from bottlenecks. The concept of a distributed block storage system can be described in several ways:

1) The distributed block store may provide a persistent block storage device for any physical or virtual machine;

2) The distributed block storage system can manage the creation, deletion and mounting/unloading of block devices;

3) Distributed block storage supports powerful snapshot functions that can be used to restore or create new block devices;

4) Distributed storage systems are capable of providing devices with different I/O performance requirements.

At present, distributed block storage is being widely used due to the advantages of elasticity and expandability, high cost performance and the like, and particularly in a cloud environment, the distributed block storage is becoming a mainstream block storage mode.

The network virtual module is specially used for managing a multi-leasing public cloud computing environment, provides flow visibility and control among and in virtual VMs for a network administrator, and aims to solve network problems by virtualization and realize a distributed virtual switching technology together with controller software. This means that the switch and controller software can create a clustered network configuration between multiple servers, eliminating the need to configure the network separately on each VM and physical host. This switch also supports VLAN trunking, visibility through NetFlow, sFlow and RSPAN, managed through the OpenFlow protocol. It has other characteristics of strict flow control, which is implemented by the OpenFlow switching protocol, and remote management functions, which enable more control through network policies.

The cloud management platform realizes the micro-service function through the container management module, and can be integrated with a network virtual module, a storage module, an authentication module and other core services in the cloud platform to realize the rapid popularization of the container.

The container technology of the container management module is dock, and network, storage and mirror image resources used by dock can be taken over completely, so that complete life cycle management of the container is realized.

And combining the arrangement function of the cloud management platform with the container management module to realize batch container management.

The interface design of the cloud platform provided by the embodiment adopts the current general OpenAPI specification. The OpenAPI specification specifies the RESTful services development process by defining a language that describes the API format or API definition. The system is very friendly to the developer, and the user can conveniently dock regardless of the language and platform used. The API is divided into a plurality of modules according to the functional modules, and is easy to find and use.

The interface call of the cloud platform in this embodiment may be directly tested on the software platform, or other tools, such as postman, may be used. The call result can be seen directly at the interface. Call formats and the like can also be seen in the document.
