In my previous article, we discussed interoperability standards currently being explored for a Multi-cloud environment.

In this article, we will discuss TOSCA one of the standards in detail.

It is an open standard developed to describe and manage the deployment and orchestration of complex applications in cloud and distributed computing environments. TOSCA provides a standardised way to define the structure and behaviour of applications and their components, making it easier to manage and automate their lifecycle across different cloud platforms.

Let’s discuss some key aspects of TOSCA standards:

Application Modeling:

TOSCA allows users to model complex applications and their components in a standardised way. This includes defining the structure of the application, the relationships between its components, and the properties and capabilities of each components.

Topology Templates:

TOSCA uses topology templates to describe the architecture of an application or service. These…
