Building Cloud-Agnostic Applications: A Guide to Flexibility and Scalability

April 25, 2024


Today, flexibility and scalability are key factors for any application's success. Building cloud-agnostic applications allows developers to harness the strengths of various cloud providers while minimizing vendor lock-in. In this article, we'll explore the process we follow at RapidCanvas in creating a cloud-agnostic AI platform, including identifying external services, building connectors, leveraging Kubernetes for deployment, and utilizing cloud marketplaces for easy installation.

1. Identifying Dependent Services

When architecting cloud-agnostic applications, it's essential to identify the external services the application relies on, such as databases, file storage, messaging queues, and authentication services. Examples of these services include:

  • Databases: Relational databases (e.g., MySQL, PostgreSQL), NoSQL databases (e.g., MongoDB, Cassandra).
  • File Storage: Object storage (e.g., Amazon S3, Google Cloud Storage), file systems (e.g., AWS EFS, Azure Files).
  • Messaging Queues: Pub/Sub systems (e.g., Amazon SQS, Google Cloud Pub/Sub), message brokers (e.g., RabbitMQ, Apache Kafka).
  • Authentication: Identity providers (e.g., AWS Cognito, Google Identity Platform), authentication as a service (e.g., Auth0, Okta).

2. Building Adaptors

Once we have identified the external services, the next step is to build connectors that abstract away the provider-specific implementation details. These connectors act as intermediaries between the AI platform, in our case, and the underlying cloud services, allowing seamless integration with multiple cloud providers. For example:

  • Database Connector: Abstracts database operations such as querying, inserting, and updating data. Supports multiple database engines through provider-specific implementations.
  • Storage Connector: Provides a unified interface for storing and retrieving files, abstracting away the differences between object storage services offered by various cloud providers.
  • Messaging Connector: Facilitates communication between different components of your application by abstracting the underlying messaging infrastructure.

3. Leveraging Kubernetes for Deployment

Kubernetes has emerged as the de facto standard for container orchestration, offering portability and scalability across different cloud environments. By containerizing the application components and leveraging Kubernetes, we are able to simplify installation and deployment of RapidCanvas on any cloud provider. Key benefits of using Kubernetes include:

  • Portability: Kubernetes abstracts away the underlying infrastructure, allowing your application to run consistently across different cloud environments.
  • Scalability: Kubernetes provides built-in mechanisms for scaling your application based on resource utilization, ensuring optimal performance.
  • Flexibility: Kubernetes' declarative configuration allows you to define your application's desired state, making it easy to update and roll back changes.

4. Utilizing Cloud Marketplaces

Cloud marketplaces offer a convenient way to discover, deploy, and manage pre-configured software solutions on various cloud platforms. By listing cloud-agnostic applications and products on these marketplaces, it becomes easier to reach a wider audience and streamline the deployment process for the customers. Key features of cloud marketplaces include:

  • One-Click Deployment: Users can deploy the application with a single click, eliminating the need for manual configuration.
  • Billing Integration: Cloud marketplaces often handle billing and subscription management, making it easy for customers to pay for usage.
  • Customer VPC Integration: Some cloud marketplaces allow the application to be deployed directly into the customer's virtual private cloud (VPC), ensuring seamless integration with their existing infrastructure.

Why Being Cloud Agnostic Is Critical For AI 

For an AI platform like RapidCanvas, being cloud-agnostic is critical for flexibility and future-proofing. It ensures the platform can run seamlessly across different cloud providers or even on-premises infrastructure. This avoids vendor lock-in, allowing customers to choose the cloud environment that best suits their needs at any given time, whether it's based on cost, specific features, or compliance regulations. This agility is essential for AI projects, which often require ongoing experimentation and adaptation.


In conclusion, building cloud-agnostic applications requires careful consideration of external services, the development of robust connectors, leveraging Kubernetes for deployment, and utilizing cloud marketplaces for easy installation. By following these principles, RapidCanvas has created a flexible and scalable application that can run seamlessly across multiple cloud environments, empowering both developers and end-users alike.
