IT operations refers to the use of information technology and tools to ensure and optimize the availability, performance, security, and efficiency of IT systems and services. The technology tree of IT operation and maintenance refers to the system of relevant technologies and knowledge that IT operation and maintenance engineers need to master, which generally includes the following aspects:
Basic skills: including Linux and Windows operating systems, network protocols, scripting languages such as shell, python perl, and common O&M tools and commands.
Service skills: including building and managing common IT services, such as web servers, database servers, file servers, mail servers, DNS servers, load balancers, firewalls, etc.
Monitoring skills: This includes the use of various monitoring tools and platforms, such as Zabbix, Nagios, Prometheus, Grafana, etc., to monitor and analyze the status, performance, metrics, and logs of the system.
Automation skills: This includes the use of various automation tools and frameworks, such as Ansible, Puppet, Chef, SaltStack, Jenkins, Git, etc., to implement configuration management, continuous integration, continuous delivery, etc.
Cloud computing skills: These include the use of various cloud services and platforms, such as AWS, Azure, Alibaba Cloud, and Tencent Cloud, to deploy and manage resources, services, and applications on the cloud.
Big data skills: This includes the use of various big data technologies and platforms, such as Hadoop, Spark, Hive, Kafka, and Elasticsearch, to process and analyze massive amounts of data.
Container skills: This includes the use of various container technologies and platforms, such as Docker, Kubernetes, Swarm, and Mesos, to implement application packaging, deployment, and management.
Security skills: This includes the use of various security technologies and tools, such as encryption, authentication, authorization, auditing, defense, infiltration, emergency response, etc., to protect the security of systems and data.
The technology tree of IT O&M is a system that is constantly updated and expanded, and IT O&M engineers need to choose appropriate technologies and knowledge for learning and practice according to their own career planning and development direction.
