openstack contains some commonly used public components

OpenStack is an open source cloud computing platform. Made up of many components. The following are some of the commonly used public components:

Nova: This is the core component of OpenStack, which provides the creation and management functions of virtual machine instances.
Swift: This is an object storage system that provides storage and management functions for large data sets.
Glance: This is an imaging service that converts virtual machine images into actual virtual machine instances.
Keystone: This is an authentication and authorization service that provides user authentication and access control functions.
Cinder: This is a block storage system that provides access and management functions to physical block devices.
Neutron: This is a network service that provides control and management functions for networks and security groups.
Horizon: This is a web interface that provides a user-friendly way to manage and use OpenStack.

These components work together to provide complete cloud computing services. These components may vary in different versions of OpenStack, but they are generally required to ensure the stability and reliability of OpenStack.

The core technologies of cloud computing include: virtualization, distributed file system, distributed database, resource management technology, energy consumption management technology, information security, etc.

Virtualization is one of the most important core technologies of cloud computing. It provides infrastructure-level support for cloud computing services and is the main driver for ICT services to rapidly move towards cloud computing. force. Many people have misunderstandings about cloud computing and virtualization, thinking that cloud computing is virtualization.

But in fact, virtualization is only an important part of cloud computing, but it cannot represent all cloud computing. The biggest benefit of virtualization is to enhance the elasticity and flexibility of the system, reduce costs, improve services, and improve resource utilization efficiency. From a performance perspective, virtualization is divided into two application modes.

The first is to virtualize a powerful server into multiple independent small servers to serve different users. The second is to virtualize multiple servers into a powerful server to complete specific functions. The core of both models is unified management, dynamic allocation of resources, and improved resource utilization. In cloud computing, these two models have many applications.

Distributed data storage technology, by storing data in different physical devices, can achieve dynamic load balancing, automatic takeover of failed nodes, high reliability, high availability, Highly scalable.

Because in a multi-node concurrent execution environment, the status of each node needs to be synchronized, and when a single node fails, the system needs an effective mechanism to ensure that other nodes are not affected. This model not only gets rid of the limitations of hardware devices, but also has better scalability and can quickly respond to changes in user needs.

Using multiple storage servers to share the storage load and using location servers to locate storage information not only improves the reliability, availability and access efficiency of the system, but is also easy to expand.

Cloud infrastructure is an important part of the Industrial Internet. It refers to the integration of computing and storage through virtualization technology. and network and other resources are brought together to provide users with scalable, pay-as-you-go services.
The main function and role of cloud infrastructure is to provide a stable, efficient and flexible operating environment for industrial Internet applications. It allows enterprises to quickly respond to changes in business needs without investing large amounts of money in purchasing and maintaining hardware equipment. At the same time, cloud infrastructure can also reduce the operating costs of enterprises and improve resource utilization, thereby enhancing the competitiveness of enterprises.
The key components of cloud infrastructure mainly include:
1. Computing resources: This is the core part of cloud infrastructure, including computing instances such as virtual machines and containers. They provide users with the computing power required to support the operation of various industrial Internet applications.
2. Storage resources: Cloud storage services provide users with data storage and management functions. This includes different types of services such as block storage, file storage, and object storage to meet the needs of different application scenarios.
3. Network resources: The cloud computing platform provides users with safe and reliable network connection services through virtual network technology. This includes virtual private network, load balancing, firewall and other functions to ensure the security of user data transmission and the stable operation of applications.
4. Management platform: The management platform of cloud infrastructure is responsible for resource scheduling, monitoring, operation and maintenance and other functions. It provides a unified user interface to facilitate users to configure and manage cloud resources.
Take Alibaba Cloud as an example. Its cloud infrastructure services include ECS (Elastic Computing Service), OSS (Object Storage Service), VPC (Virtual Private Network), etc. Through these services, users can easily build and manage their own industrial Internet applications and achieve rapid business development and innovation. At the same time, Alibaba Cloud also provides a series of security protection measures, such as DDoS protection, data encryption, etc., to ensure the security and privacy protection of user data.
