How do I monitor services in microservices?
The Principles of Microservice Monitoring
- Monitor Containers and What’s Running Inside Them.
- Leverage Orchestration Systems to Alert on Service Performance.
- Be Prepared for Services that are Elastic and Multi-Location.
- Monitor APIs.
- Map Monitoring to Your Organizational Structure.
What is the service discovery in microservices?
Service discovery is how applications and (micro)services locate each other on a network. Implementations include both a central server(s) that maintain a global view of addresses and clients that connect to the central server to update and retrieve addresses.
Are Microservices meant for small businesses?
Microservices, aka Microservice Architecture, is an architectural style that structures an application as a collection of small autonomous services, modeled around a business domain. In microservice architecture, each service is self-contained and implements a single business capability.
Do you need to list all versions of a microservice?
In some cases it may be necessary to have different versions of the same microservice running at the same time in an environment. This can be easily solved, by listing every version of a service that should be deployed in the corresponding tracker file.
Can a tracker be used to version a microservice?
Using the tracker repository will probably make it very tempting to start treating your microservice system as a “distributed” monolith. It’s easy to see a strategy of versioning the contents (using git-tags) and promoting only these “versions”. Conscious effort should be made to not do this.
How do we version our microservices, learn.write.repeat?
How do we version our microservices? A good and widely adopted approach is semantic versioning. It has a three parts string: MAJOR.MINOR.PATCH. The MAJOR version should increment only when the changes are breaking the clients. The MINOR version should increment when the changes are not breaking the clients. A PATCH version change signals bug fixes.
Is there a long release train for microservices?
Following the microservices philosophy, there should never be a long release train where every team has to get in line. The team that builds service “A” can release an update at any time, without waiting for changes in service “B” to be merged, tested, and deployed.
