Open Application Model (OAM) is a specification for managing cloud-native applications that provides a more flexible way to define and deploy applications.
In today’s rapidly evolving digital landscape, the ability to develop and deploy applications quickly and efficiently is paramount. Platform dependencies, vendor lock-in, and complicated deployment procedures are just a few of the difficulties that traditional approaches to application management frequently face.
However, a new era of application development and deployment has begun with the rise of OAM. It provides a standardized and platform-neutral approach that frees you from getting bogged down in the specifics of particular cloud platforms and enables you to concentrate on the central logic of your applications.
We will explore OAM’s capabilities, advantages, and how it enables you to unleash the full potential of your cloud-native applications in this blog. Get ready to embrace a more flexible, scalable, and future-ready approach to application management with OAM.
As you may be aware, the ability of cloud-native applications to offer scalability, flexibility, and agility to businesses has led to their significant rise in popularity in recent years. However, managing these applications can be difficult because of their distributed nature and intricate architecture.
Due to the need for a more dynamic and automated approach, cloud-native applications are not well-suited for traditional application management techniques. Furthermore, it is challenging to effectively manage and monitor cloud-native applications due to their high level of abstraction.
The Open Application Model (OAM) was created as an open-source specification for defining cloud-native applications to address these issues. Cloud-native applications are simpler to manage and scale when developers use OAM to abstract away the infrastructure specifics and concentrate on defining the application components and their relationships.
OAM aims to give developers more control and flexibility over the management of cloud-native applications while also making it simpler to build and deploy those applications across various platforms. Cloud Native Computing Foundation (CNCF) is now responsible for maintaining OAM, created by Microsoft and Alibaba Cloud.
Without having to rewrite or reconfigure your applications, OAM enables you to define application components and their relationships, making deploying and managing applications across various environments simple. OAM makes it easier for developers to concentrate on writing code and providing value to their users by streamlining the process of creating and managing cloud-native applications.
The traditional methods for developing and deploying cloud-native applications frequently have drawbacks like platform dependencies, vendor lock-in, and convoluted deployment procedures. To overcome these difficulties, OAM applies the “separation of concerns” principle and offers guidelines for creating applications. It outlines the following obligations and roles:
To aid in the development of applications, several fundamental concepts in the world of OAM are defined. These elements function as abstract concepts with various potential applications:
These core concepts serve as OAM’s building blocks and add to its adaptability and scalability. Understanding these elements will help you make better use of OAM when creating and deploying cloud-native applications.
There are many advantages to managing cloud-native applications with OAM.
OAM’s approach to application management sets it apart from other container orchestration tools like Kubernetes. OAM offers a higher-level abstraction for managing cloud-native applications in contrast to Kubernetes, which focuses on managing infrastructure resources.
The process of deploying and managing complex distributed applications can be made easier by OAM, which offers a declarative model for describing applications, their components, and their relationships.
OAM offers a common language for describing application requirements and constraints, which makes it easier for developers and operations teams to collaborate.
Last but not least, OAM improves portability between various cloud environments by removing the underlying infrastructure and concentrating on the application layer.
In general, OAM offers a more comprehensive approach to cloud-native application management that can assist organizations in enhancing their IT operations’ efficiency, agility, and resilience.
The architecture of OAM comprises two main components: the Application Configuration Controller and the Application Component Controller. The Application Configuration Controller manages the overall application configuration, while the Application Component Controller manages the individual components that make up the application. These elements could include the microservices, containers, and other resources needed to run the application.
The ability for developers to define applications declaratively is one of the main advantages of using OAM. Developers may specify the number of replicas that should be active for each component as well as the resources needed by each replica, for instance. This simplifies managing and scaling applications and guarantees that they always operate in the desired state.
OAM will likely become a crucial tool for any developer in this field as it continues to develop and gain traction in the cloud-native community.
Advantages of using the Open Application Model (OAM) in managing cloud-native applications:
The requirement for specialized skills to successfully implement and manage OAM-based applications is one of the most significant challenges. For your team to have the knowledge required to use OAM effectively, investing in additional training and resources might be necessary.
The potential compatibility problems that might develop when integrating OAM into current systems should also be considered. It might be challenging to fully integrate OAM without upsetting existing systems, depending on your current infrastructure’s complexity.
Understanding your organization’s needs and objectives is crucial when implementing OAM to overcome these difficulties. Doing so allows you to develop risk-mitigation strategies and identify potential compatibility problems before implementation.
Working with a certified OAM service provider or consultant is another option to consider. They can assist you with the implementation process and ensure your team has the knowledge and tools necessary to use OAM effectively.
The Synergy of Open Application Model and DevOps
The Open Application Model (OAM) and a DevOps platform have a complementary relationship. An established method for describing and deploying cloud-native applications is defined by the OAM specification. With its declarative approach to application deployment, it enables programmers to define the desired state of a given application without revealing the specifics of the underlying infrastructure.
On the other hand, a DevOps platform is a group of instruments, procedures, and procedures that enables organizations to automate and streamline their software development and delivery procedures. It ensures quicker and more reliable application deployments as well as improved collaboration between the development and operations teams.
The effectiveness and consistency of application deployments can be improved by combining an OAM and a DevOps platform like Ozone. The OAM offers a uniform language for describing the relationships between application components, and a DevOps platform like Ozone standardizes and automates deployments based on those specifications. Through this integration, businesses can improve the scalability, maintainability, security, and agility of their application development and deployment lifecycles.
Ozone is focused on eliminating every complexity of a DevOps team. It simplifies and automates containerized and decentralised application deployments across hybrid cloud and diverse blockchain networks. Ozone integrates seamlessly with major tools across CI, CD, analytics and automation to support your software delivery end to end for even the most complex scenarios.
