自学云计算基础知识(云计算基础知识)

The main things to learn about cloud computing are as follows:

Phase 1: Introduction to the basics of cloud computing

Learning content : Computer network knowledge, 5G network protocols and network planning, TCP/IP protocol, data transmission, switches and routers, revealing viruses and Trojans, building a LAMP website platform, etc.

Learning of operating systems and scripting languages, knowledge of common Linux commands, server configuration, domain name resolution, shell programming and firewalls. This part of the content is also part of the technical content of the operation and maintenance positions that we used to talk about, and cloud computing is also an upgrade and evolution based on traditional operation and maintenance.

The second stage: cloud performance management

Cloud performance management is also the type of cloud service that is currently in demand by enterprises. Performance management refers to the capabilities displayed by management objectives. and a comprehensive reflection of the management efficiency, effects, and benefits achieved. Then the performance management based on the cloud platform is more effective for demand management such as energy efficiency data collection, transmission and storage, real-time monitoring of energy efficiency, and energy efficiency analysis, and has higher security and reliability.

And based on the cloud platform, it can help realize automated management of applications without the need for separate maintenance personnel, directly reducing the enterprise's system maintenance costs.

Learning content: web basics and development, web server cluster, nginx+tomcat load balancing and dynamic and static separation, database applications (MySQL database management, backup and recovery, master-slave replication and read-write separation, MySQL-mmm Special knowledge such as realizing MySQL high availability), virtual server LVS deployment and clustering, redis deployment and optimization, remote synchronization Rsync, etc.

The third stage: cloud native platform management

Learning content: Distributed storage KVM+GFS, KVM high availability, cloud platform Openstack module management and deployment, private cloud platform, container Docker, Kueberinetes deployment and management, cloud native architecture deployment, etc.

After completing this stage, you can ensure the normal operation of large-scale servers and enable developers to effectively carry out development work based on cloud platforms. Cloud native platforms are a new trend. Cloud service providers can provide customers with complete cloud native systems, and customers using Java can make a very smooth transition to a modern development environment, and by increasing all key indicators of virtual applications (RAM consumption , speed, etc.) to save costs.

The maturity and stability of the cloud platform has also provided new development areas for our Java development engineers. At present, our Java majors will also learn technical content such as docker and K8S. , allowing our students to have more industry fields to choose from after graduation.

The fourth phase: DevOps automated management

Learning content: Monitoring platform deployment and application Zabbix, enterprise-level distribution, saltstack, ansible deployment, Git, Jenkins, Python development, etc. The emergence of Devops makes communication and cooperation between development and operation and maintenance personnel more efficient, making software construction, testing, and release faster, more frequent, and more reliable.

DevOps is a framework that enables faster delivery and responds to market changes; it focuses more on business improvement and enhancement

The fifth stage: cloud security management

< p>Cloud security management is mainly about learning network security knowledge. As more companies upload their data, systems, and applications to cloud platforms for business operations and management, information security issues in the process have also attracted much attention from users. In particular, it is very vulnerable to attacks during the data upload process. A set of A complete data migration solution requires the full participation of network security technicians.

Learning content: Cloud security and MPA 2.0, physical environment and architecture security, transmission security and boundary protection, web security, database security, security operation and maintenance, etc.

Cloud security, as one of the development trends of cloud services in 2023, integrates emerging technologies and concepts such as parallel processing, grid computing, and unknown virus behavior judgment, and uses a large number of meshed clients to control software in the network. Abnormal behavior monitoring, obtaining the latest information on Trojans and malicious programs on the Internet, transmitting it to the server for automatic analysis and processing, and then distributing virus and Trojan solutions to each client.

The prospect of big data is very good. Majors like big data are better in first-tier cities, and the teaching staff can keep up. The salary of employment is also considerable. You can learn big data in the order of the road map.

0 There is no problem in learning Java based on it. The key is to find For a reliable Java training institution, you can have a deep understanding of the institution's reputation and ask people around you who know the institution. In addition to reputation, you can also learn about the following aspects of the institution:

1. Strong teaching staff

p>2, the most important thing is the teaching team. No matter you find a job or what role you play at work, you will love yourself more and more. Professional Java technology, perhaps most of the professional Java technology comes from your professional Java teachers. A good Java training institution must have strong teaching staff.

2. Improved employment security

2 effect is to provide you with a good development platform, that is, to be able to provide you with good employment. Guarantee, so that students can learn practical knowledge, and provide one-on-one employment guidance to Java students to ensure that students find their own psychological jobs.

3. The tuition fee is cost-effective

2 effect. If you are in Working on a platform led by expert Java teachers and provided by the Java Training Institute itself, you'll get more out of your investment than ever before.

I hope you will succeed in your studies as soon as possible.
