​
What are Apps?

In the context of the Cloud Native Application Platform (CNAP), apps represent the applications, services, or entire deployment environments that users can deploy and manage through the platform. These apps are typically packaged as Cloud Native Application Bundles (CNABs), which encapsulate all the necessary components and configurations for deploying and managing complex, multi-service applications or environments.

​
Key Concepts

  1. App Store: CNAP provides an app store-like interface where users can browse, select, and deploy various applications or deployment configurations.
  2. CNAB Integration: Apps in CNAP are built on the CNAB specification, ensuring standardized packaging and management across different cloud environments.
  3. Customization: Users can often customize app configurations before deployment to suit their specific needs.
  4. Lifecycle Management: CNAP provides tools for managing the entire lifecycle of an app, from initial deployment through updates and eventual decommissioning.
  5. Multi-cloud Support: Apps can be deployed across various cloud providers or on-premises infrastructure, leveraging CNAP’s multi-cloud capabilities.
  6. Installs: When an app is deployed, it becomes an “install”. An install can represent more than just a single application - it can encompass entire deployments on Kubernetes clusters, web hosting providers, or other deployment targets.

​
Types of Apps

Apps in CNAP can vary widely, including but not limited to:

Web Applications

Full-stack web apps, from simple static sites to complex dynamic applications.

Databases

Various database systems, including relational, NoSQL, and time-series databases.

Message Queues

Messaging systems for asynchronous communication between services.

Monitoring Tools

Applications for monitoring system health, performance, and user behavior.

Development Environments

Preconfigured development setups for various programming languages and frameworks.

Data Processing Pipelines

Tools for ETL processes, data analysis, and machine learning workflows.

Microservices Architectures

Complete setups for deploying and managing distributed microservices.

Deployment Environments

Entire infrastructure setups for staging, testing, or production environments.

​
App Management

CNAP offers several features for managing apps:

  • Custom Actions: Ability to execute predefined actions created by app developers, facilitating day-to-day operations and maintenance tasks.
  • Deployment: Easy-to-use interfaces for deploying apps to your chosen infrastructure.
  • Monitoring: Tools for monitoring the health and performance of your deployed apps and environments.
  • Updating: Streamlined processes for updating apps to newer versions.

​
Benefits of CNAP Apps

  1. Consistency: Standardized packaging ensures consistent management across different kinds of apps.
  2. Simplicity: Complex multi-service applications or entire environments can be deployed with minimal configuration.
  3. Portability: Apps can be easily moved between different cloud providers or infrastructure setups.
  4. Version Control: Clear tracking of app versions and the ability to roll back if needed.
  5. Integration: Apps can often integrate with other CNAP features like monitoring, logging, and security tools.

​
Getting Started with Apps

To start using apps in CNAP:

  1. Browse the app store to find the application or deployment configuration you need.
  2. Review the app’s documentation and requirements.
  3. Configure the app settings as needed for your environment.
  4. Deploy the app using CNAP’s deployment tools, creating an install.
  5. Monitor and manage your install through the CNAP dashboard.

By leveraging apps in CNAP, you can significantly simplify the process of deploying and managing complex applications and environments in cloud-native infrastructures.
