Application Market

Application Market #

Overview #

The application market is a public application warehouse on the platform.The application market generates application services (CafeDeployment) with one click based on the application templates defined by OAM model. You can quickly create application services by customizing OAM templates.

OAM aims to promote the application management technology to the direction of light operation and maintenance through a brand-new model of application definition, operation and maintenance, distribution and delivery.For Kubernetes,OAM is not only a standard application definition project (similar to Kubernetes Application CRD project, which is no longer active),but also a platform-level project that focuses on packaging,norganizing and managing various operation and maintenance capabilities in Kubernetes, and connecting operation and maintenance capabilities with applications.By simultaneously providing the two core functions of defining applications and organizing and managing the operation and maintenance capabilities of applications.

In OAM,an application contains three core concepts:

  • Component：Component that make up the application, which may include microservice collection, database and cloud load balancer.
  • Trait：Describe the collection of application operation and maintenance features,such as elastic scaling and Ingress.They are essential to the operation of applications,but they are implemented differently in different environments.
  • Application Configuration：Finally,in order to translate these descriptions into specific applications, operation and maintenance personnel use application configuration to combine components and corresponding features to build specific instances of applications that should be deployed.
