Operation and Maintenance Engineers are responsible for maintaining and ensuring the high availability of the entire service, as well as continuously optimizing the system architecture to improve deployment efficiency and optimize resource utilization to improve the overall ROI.
Operation and Maintenance Engineers are faced with the biggest challenge is the management of large-scale clusters, and how to manage hundreds of thousands of servers to guarantee high availability of the service is the biggest challenge facing the Engineers. guaranteeing high availability of services is the biggest challenge facing operations engineers.
No matter what the operation and maintenance, the most basic responsibility of the operation and maintenance engineers is to be responsible for the stability of the service, to ensure that the service can be 7 * 24H uninterruptedly for the user to provide services. On top of that, the main responsibilities of the operation and maintenance engineers are as follows:
Quality: to ensure and continuously improve the availability of services, to ensure the safety of user data, and to enhance the user experience.
Efficiency: Use automated tools/platforms to improve the engineering efficiency of software in the development lifecycle.
Cost: Optimize service architecture and performance tuning by technical means; reduce cost and improve ROI by optimizing the combination of resources.
From the perspective of product lifecycle:
1. Before the release of the product: Responsible for participating in and reviewing the reasonableness of the architectural design and the operability and maintainability to ensure efficient and stable operation after the release of the product.
2. Product release phase: responsible for using automation technology or platform to ensure that the product can be efficiently released online, and then can be quickly and stably iterated.
3. Product operation and maintenance phase: responsible for ensuring that the product 7 * 24H stable operation, during this period of time on the emergence of a variety of problems can be quickly located and resolved; in the daily work of the system architecture and deployment of continuous optimization of the reasonableness, in order to enhance the stability of the system services.
