Work content of service governance

The actual work of service governance consists of two parts ： One stop service management platform 、 Pervasive service development framework . The one-stop service governance platform serves as the base for service governance output , The most important role is to solidify the service governance specification . Service governance norms have evolved from experience to wiki、 from wiki The development trend to the platform also shows that the service governance specification is a very important bridge between the business side and the service governance team .

Pervasive service development framework , It is a very important starting point for the service governance team , What the platform can do is limited , The widely used development framework can do more . Universality is the most important advantage of a service development framework , How to combine with the business side 、 It is very important to improve the universality of the service development framework . In terms of content , The specific work scope of service governance can be summarized as follows .

• System visibility

Mainly the work of the service governance platform , It specifically includes the static description of the service , For example, basic service information 、 Service level 、 Global dependency Topology 、 Routing relationship 、IDL（SDK）、 jurisdiction 、SLA、 Flow control strategy, etc , The service governance platform needs the ability to help us sort out the dependency levels 、 Determine the service level . Service real-time topology , Specifically, it includes the global traffic topology 、 Statement audit, etc , The service governance platform needs to be able to display real-time traffic status , Locate the online problem based on the scene .

• The system can be operated

Get through the service governance platform and service development framework , Output capabilities for other platforms , Specifically, it includes route switching 、 Degradation plan, etc .

• System traceability

Record the problem scene , Such as traffic recording 、 Log recording, etc , Then use the appropriate tracking and traceability system , Replay and trace the common problems in typical scenarios , Achieve “ One recording , Play back many times ”. Based on tracing and playback mechanism , Root cause positioning can be solved 、 Scenario analysis and other issues .

• The system is predictable

It refers to the behavior of predicting the next period of business , Like traffic 、 Capacity 、 Safety, etc , At the same time, the potential risks of the system are detected through various tools and platforms . Take capacity planning as an example , It is necessary to be able to predict and judge the business growth trend and operation activities in the next period of time , Determine the possible traffic peak and the impact on the system capacity ; Next, through the full link voltage test 、 The possible capacity risk of the system is detected by means of single system pressure measurement .

• The business is fully focused

The purpose of service governance is to solve the problems of business stability and efficiency , The business must be fully focused , Starting from business , Focus on solving the current pain points of the business .

In essence, service governance is to solve a series of challenges after microservicing , Such as efficiency governance 、 Stability governance 、 Effect management 、 Performance cost management, etc . These governance measures generally work in the design and development stage , We can call it “ Positive governance ”, After the service goes online , It can be based on various data at run time , Conduct comprehensive management and feedback , So as to form a governance closed loop .

In the above service governance closed loop , Through multi-dimensional measurement data collection , Combine static service metadata information , Constitute a complete service governance data set , Then based on these data, comprehensive measurement and Analysis . Corresponding control and control measures will be generated according to the analysis results , Conduct comprehensive management from online and offline dimensions , At the same time, the negative feedback of the governance results , As input for further governance .
