Use Cases of Open Application Model

What is OAM?

Open Application Model (OAM) is an open-source standard for building cloud-native applications, It is designed to enable developers to build and deploy applications on Kubernetes without requiring them to have in-depth knowledge of the underlying infrastructure.

OAM provides a higher-level abstraction for application developers to describe the application components and their relationships, which makes it easier for developers to focus on the business logic of their applications.

In this blog post, we will explore some of the best use cases of OAM and how it can be used to build cloud-native applications.

• Microservices-Based Applications

  One of the best use cases of OAM is in the development and deployment of microservices-based applications. Microservices architecture is becoming increasingly popular as it allows developers to break down monolithic applications into smaller, independent services that can be developed, tested, and deployed independently. However, managing these microservices can be challenging, especially when it comes to coordinating their deployment and scaling.

  With OAM, developers can define the components of the microservices application as well as their dependencies and requirements, such as CPU and memory usage, network connectivity, and storage requirements. This information can be used by Kubernetes to ensure that the application is deployed and scaled correctly.

  For example, let's say that you are building an e-commerce application that consists of multiple microservices, such as a shopping cart service, a payment service, and an order tracking service. With OAM, you can define the dependencies between these services and specify the resources required by each service. This makes it easier to manage the microservices application, as Kubernetes can ensure that the services are deployed and scaled correctly.

• Complex Applications

  Another use case of OAM is in the development of complex applications that require multiple services to work together. With OAM, developers can define the dependencies and requirements of each service, as well as how they should be connected. This makes it easier to develop and deploy complex applications, as it provides a higher-level abstraction for developers to describe the application components and their relationships.

  For example, let's say that you are building a healthcare application that consists of multiple services, such as a patient information service, a diagnosis service, and a treatment service. With OAM, you can define the dependencies between these services and specify how they should be connected. This makes it easier to manage the healthcare application, as Kubernetes can ensure that the services are deployed and scaled correctly.

• Operational Characteristics

  OAM also provides a standard way of defining the operational characteristics of an application, such as monitoring, logging, and security. This makes it easier to manage the application in production, as it provides a consistent way of managing these operational aspects.

  For example, let's say that you are deploying a microservices application that requires monitoring and logging. With OAM, you can define the monitoring and logging requirements of each service, such as which metrics should be monitored and where the logs should be stored. This makes it easier to manage the microservices application in production, as Kubernetes can ensure that the monitoring and logging requirements are met.

Conclusion

In conclusion, OAM provides a higher-level abstraction for application developers to describe the application components and their relationships, which makes it easier to manage the application components and ensure that they are deployed and scaled correctly. The best use cases of OAM are in the development and deployment of microservices-based applications and complex applications that require multiple services to work together.

Additionally, OAM provides a standard way of defining the operational characteristics of an application, which makes it easier to manage the application in production. If you are building cloud-native applications on Kubernetes, OAM is a standard that you should consider using.
