What are Cloud-Native Principles?

Cloud-native principles are a set of cloud-specific guidelines around app creation. They aim to guide app development/design and utilize cloud computing environments. 

Scalability, resilience, and agility in your apps should be at the forefront of your mind when using cloud-native principles. Characteristics include: 

• Microservices Architecture: Dividing apps into smaller and loosely coupled services. Development, deployment, and scaling should all be independent. 
• Containerization: Package apps/dependencies into portable containers. You should do this if you wish to consistently deploy apps across varying environments.
• Orchestration: Automate containerized apps’ scaling, deployment, and management for resource utilization.  
• DevOps Culture: Your DevOps team should be collaborative across security, operations, and development. 
• Continuous Delivery: Focus on facilitating frequent/automated new feature/improvement releases for user experience.

Some of the agility and scalability aspects associated with cloud-native principles are: 

• Microservices Architecture: Independent deployment/development for more frequent release updates and concurrent working. 
• Containerization and Orchestration: Containers are used for consistency/portability; orchestration tools automate app deployment/scaling for adaptation to changing demands. 
• DevOps and Continuous Delivery: A collaborated DevOps culture should streamline the software development lifecycle, as should a constant delivery streamline. 

DevOps’ role in a cloud-native environment is: 

• Collaboration: DevOps must stop development, operations, and security team silos. Shared responsibility and a collaborative culture are crucial.
• Automation: Continuous delivery uses automation for building, testing, and deployment; the primary aim is to stop manual errors and speed up release cycles.  
• Feedback Loops: Continuous feedback and monitoring are essential; teams must identify and address issues quickly to enhance app quality/reliability.

Cloud-native apps address these issues through: 

• Distributed Architecture: App components are distributed across microservices and containerization, using different servers and availability zones. 
• Health Checks and Self-Healing: Cloud-native apps use self-healing mechanisms to detect/recover from failures, and they should also utilize health checks.
• Load Balancing: Distribute traffic across multiple app instances; this is imperative for high availability/performance during peak loads.

Businesses need to address with each of the following when implementing a cloud-native approach:

• Cultural Shift: A DevOps-focused cultural shift to one where continuous improvement, automation, and collaboration are emphasized is a necessity.
• Complexity: You need the right skills and expertise to manage cloud-native architectures.  
• Cost Management: Due to the cost of cloud resources, it’s wise to plan and manage budgets and expectations in advance. 
• Bezpieczeństwo: You need strong security measures in your cloud-native apps for sensitive data protection and to stop unauthorized access.
