One: the operation and maintenance engineer should ensure the stability of the online system, which is the core value of the operation and maintenance personnel. Focusing on this is a very big topic, which will be refined later.
2. Infrastructure: Safety, quality, efficiency and cost are the four aspects that operation and maintenance personnel can carry out operation and maintenance work. Around these four aspects, we need to formulate norms and processes, build corresponding systems to ensure efficiency, standardize and improve efficiency, and so on: three-dimensional monitoring system.
Precautions:
Efficiency of speed measurement, backup and disaster tolerance: system construction to improve operation and maintenance efficiency, standardization of machine initialization, standardization of software installation, standardization of monitoring, etc. , security to improve efficiency, batch deployment of scripts, etc. : Internet security, system support, cgi scanning, etc. Cost: budgeting, etc. , rationally optimize deployment and balance cost and experience.
