What is Cloud Native?

 

Cloud Native is a way of developing and deploying applications that are designed to run in a cloud computing environment. It is an approach that takes full advantage of the capabilities of cloud platforms, such as elastic scaling, automatic load balancing, and dynamic provisioning of resources. Cloud Native applications are typically built using a combination of containers, microservices, and dynamic orchestration.

 

Containers are lightweight, portable unit of software that packages an application and its dependencies. Containers provide a consistent runtime environment across different platforms, making it easier to move applications between development, testing, and production environments. Microservices, on the other hand, are a way of breaking down large, monolithic applications into smaller, independent services that can be developed, tested, and deployed separately. This approach allows for greater flexibility, scalability, and fault tolerance.

 

Dynamic orchestration is the process of automatically managing and scaling the deployment of containerized applications. This is typically done using a container orchestration platform, such as Kubernetes, which automates the deployment, scaling, and management of containerized applications.

Cloud Native vs Traditional Architecture

 

Cloud-native architecture is a modern approach to building and deploying applications that leverages the benefits of cloud computing. Traditional architecture, on the other hand, is a more traditional approach that relies on on-premise infrastructure and monolithic applications. In this section, we will explore the differences between cloud-native and traditional architecture, their benefits, and their drawbacks.

 

Cloud Native Architecture:

 

Cloud-native architecture is designed to take full advantage of the capabilities of cloud computing, such as scalability, resilience, and elasticity. It is built around the principles of microservices, containers, and dynamic orchestration, which enable developers to build, test, and deploy applications more quickly and with greater efficiency.

 

One of the primary benefits of cloud-native architecture is its scalability. With cloud-native architecture, applications can be scaled up or down automatically based on demand, ensuring that resources are always available to meet user needs. Additionally, cloud-native applications are typically built using microservices, which are small, modular components that can be updated or replaced without impacting the entire application.

 

Another benefit of the cloud-native architecture is its resilience. Cloud-native applications are designed to be fault-tolerant, with built-in mechanisms for automatic failover, load balancing, and self-healing. This ensures that applications are always available and responsive, even in the face of unexpected failures or traffic spikes.

 

Finally, cloud-native architecture is highly portable. Applications built using cloud-native principles can be easily moved between cloud providers, enabling organizations to take advantage of the best pricing and services available.

 

However, there are also some drawbacks to cloud-native architecture. One of the biggest challenges is its complexity. Cloud-native applications are composed of multiple services, each with its own container and orchestration requirements. This can be challenging to manage and requires specialized skills.

 

Traditional Architecture:

 

Traditional architecture, also known as monolithic architecture, is a more traditional approach to building and deploying applications. In this approach, applications are typically built using a single, monolithic codebase, and are deployed on on-premise infrastructure.

 

One of the primary benefits of traditional architecture is its simplicity. With a traditional architecture, developers only need to manage a single codebase, making it easier to maintain and troubleshoot applications. Additionally, traditional architecture is typically more suitable for applications that have stable and predictable usage patterns.

 

However, there are also some drawbacks to traditional architecture. One of the biggest challenges is its lack of scalability. Traditional applications are typically deployed on a fixed number of servers, which can lead to resource constraints and performance issues during periods of high traffic. Additionally, traditional applications are often difficult to update or modify, as changes to one part of the application can have unintended consequences on other parts.
