With the rapid development of the Internet and technology, many novel industries have emerged, such as network operation and maintenance and network security operation and maintenance.
Literally, there is not much difference between the two, so many people easily confuse the two.
What is the difference between system and network operation and maintenance?
A partial system (linux, docker, k8s)
A partial network (data communication, router software, hardware) So, what is the difference between the two? Judging from the recruitment of JD, there are quite a lot of differences in the work content of the two.
Compared with network security operation and maintenance, network operation and maintenance is a relatively basic operation and maintenance.
It is mainly the production arrangement and handling activities adopted to ensure the normal, safe and effective operation of the telecommunications network and business. Responsible for protecting and ensuring the availability of the entire service, while continuously optimizing the system architecture to improve deployment efficiency. In layman's terms, it is the operation and protection of network-related network equipment in the IT architecture.
And system operation and maintenance + cloud computing development, you will become a professional technician with an annual salary of one million (first-tier cities).
What does a cloud computing system operation and maintenance engineer do?
The cloud computing operation and maintenance position involves whether the cloud computing platform can run smoothly and smoothly, so the operation and maintenance engineers need to do relatively rich work content, which involves not only traditional network operation and maintenance knowledge, but also virtualization, management and control, Storage, security and other related knowledge. In addition, operation and maintenance engineers also need to work on program development in order to complete large-scale automated service deployment, which also puts forward higher requirements for operation and maintenance engineers
What do you need to learn as a cloud computing network operation and maintenance engineer? 1. Operating system basics and command line The Linux operating system and its command line can be said to be the basic knowledge that every programmer should master, and it is also the "traditional art" of operation and maintenance engineers, and cloud computing operation and maintenance engineers are no exception. This part of the knowledge is very practical. It is recommended to install an Ubuntu locally on the computer or through a virtual machine, or buy a cloud server on Alibaba Cloud, instead of just reading books or videos.
2. Computer network DevOps is the collective name of development and operation and maintenance operations. Therefore, cloud computing operation and maintenance also needs to master the core knowledge of computer science that developers must learn. In addition to operating systems, computer networks are also important content to master. In addition to understanding the OSI seven-layer network model, process communication mode, TCP/IP protocol, HTTP/HTTPS, packet capture, iptables and other network and security knowledge required for local or self-built server operation and maintenance; it is also recommended to use cloud service providers Provided products and services to practice learning, such as the use of Alibaba Cloud's cloud server CVM, object storage COS, cloud database MySQL, load balancing, NAT gateway, private network, CDN, message queue and other products to gain an in-depth understanding of some cloud computing-related services And the knowledge related to the computer network involved behind it.
3. Compilation and deployment of the development environment can start from the deployment and deployment of basic LAMP, LNMP, Wordpress and some popular open source projects to cloud services, master Nginx, Tomcat, Apache and other web servers, load balancing, MySQL, Redis database and cache . The above knowledge is basically what traditional operation and maintenance engineers need to master. Of course, it is also the basis of cloud operation and maintenance. Cloud computing operation and maintenance (DevOps engineers, SRE engineers, etc.) mainly need to master the ecology and culture of cloud computing products:
4. Cloud native foundation Docker containerization and Kubernetes cluster can be said to be the most important foundation of cloud computing, and it is recommended to start with hands-on practice when learning. In actual combat, it is recommended to install and deploy the Docker environment locally, Kubernetes cluster, and use the online hosting Kubernetes provided by the cloud service provider (such as Alibaba Cloud container product ACK) to learn, so that it is close to the real environment of the actual production of the enterprise. Although the official technical documentation of Docker and Kubernetes is a good introductory tutorial, there are still some inevitable "pitfalls" for many novices.
6. Microservices, DevOps, and cloud-native monitoring In terms of microservices, DevOps, and cloud-native monitoring, in addition to mastering basic technical products, such as Jenkins, Prometheus, etc., it also involves the process and process of some enterprises going to the cloud and cloud-native landing For methodology, it is recommended to read related books such as "Cloud Native DevOps Based on Kubernetes", "Kubernetes in Action", "Cloud Native Patterns", "Kubernetes Design Patterns" (Kubernetes Patterns).
