Navigating the Cloud-Native Landscape - Chapter III

Cloud Native vs. Native Cloud - Which Path to Choose?

When considering modern cloud strategies, it’s crucial to distinguish between Cloud Native technologies, like Kubernetes, and Native Cloud technologies provided by cloud vendors such as AWS, Azure, and Google Cloud, including services like EC2, Lambda, and Google Cloud Functions.

Customization

Cloud Native platforms allow for deep customization, such as creating tailored base images, which is essential for specialized workloads (e.g., financial services with strict compliance needs). In contrast, Native Cloud services like AWS Lambda limit the ability to modify the environment, making them better suited for standard, lightweight applications like event-driven microservices or when you want short time-to-market.

Scalability

Cloud Native solutions, particularly Kubernetes, excel in cost-effective scalability. For example, global e-commerce platforms needing to handle fluctuating traffic spikes benefit from Kubernetes' ability to scale across multiple nodes and regions seamlessly. Native Cloud services, like EC2 auto-scaling, are more suitable for predictable scaling needs, such as hosting a SaaS product with fixed capacity requirements.

Responsibility

In Cloud Native environments, you're responsible for managing the underlying infrastructure (e.g., setting up, monitoring, and securing your Kubernetes clusters). This is ideal for organizations with dedicated DevOps teams who need full control over their infrastructure, like large-scale enterprise applications. Native Cloud options reduce operational overhead by offloading infrastructure management to the cloud provider, making it suitable for smaller teams or startups looking to deploy fast with minimal DevOps effort.

Portability

Cloud Native is the go-to choice when application portability is critical. For example, multinational companies operating in different regulatory environments might need to move workloads between AWS, Azure, and on-premise environments without re-engineering the application. With Kubernetes, you can lift and shift across platforms more easily. Native Cloud services like Azure WebApps are more entrenched in their ecosystem, making migrations to other clouds more challenging and time-consuming.

Cost Efficiency

In Cloud Native, you only pay for the Kubernetes cluster resources you actually use. This can lead to significant cost savings for microservices architectures, where applications are split into numerous small, independent services, such as a fintech company running multiple APIs. Native Cloud services, however, often involve additional resource costs, such as paying separately for compute, storage, and networking in a traditional EC2 setup. This may lead to higher costs for microservices deployments.
