Cloud Friendly vs Cloud Native: Which One to Choose?

Learn the key differences between cloud-friendly and cloud-native approaches and discover which one is the best fit for your business.

In the world of cloud computing, businesses are constantly faced with decisions regarding the architecture and design of their applications. Two popular approaches that often come up in discussions are Cloud Friendly and Cloud Native. These terms may seem similar, but they actually represent distinct approaches with their own set of benefits and considerations. In this article, we will delve into the world of Cloud Friendly and Cloud Native, explore their core differences, weigh their pros and cons, and consider factors that businesses must take into account when making a choice.

Understanding the Basics: Cloud Friendly and Cloud Native

Defining Cloud Friendly

Cloud Friendly applications are designed to operate and deliver content efficiently in cloud environments. They are typically built on legacy architectures that have been modified to leverage cloud infrastructure. They often rely on a blend of on-premises and cloud resources, combining traditional hardware with the benefits of cloud services.

By adopting Cloud Friendly architecture, businesses can take advantage of some cloud features and services, such as storage and compute, while still maintaining certain aspects of their existing infrastructure. This approach allows for a gradual transition to the cloud, minimizing disruption and maximizing compatibility with legacy systems.

For example, imagine a company that has been using an on-premises data center for years. They have invested heavily in their infrastructure and have specific requirements that cannot be easily migrated to the cloud. However, they also want to take advantage of the scalability and cost-effectiveness of cloud services. By adopting a Cloud Friendly approach, they can start by moving certain non-critical workloads to the cloud while keeping their core systems on-premises. This allows them to experience the benefits of the cloud without completely overhauling their existing infrastructure.

Defining Cloud Native

On the other hand, Cloud Native applications are purpose-built for the cloud. They are designed from the ground up to capitalize on the unique features and capabilities provided by cloud platforms. These applications are typically developed using cloud-native technologies, such as containers and microservices, and are designed to be scalable, resilient, and highly performant.

Cloud Native applications take full advantage of cloud services, such as auto scaling and serverless computing, and are built with the assumption that they will run on cloud infrastructure. They are inherently flexible and adaptable, allowing businesses to quickly respond to changing market demands.

For instance, let's consider a startup that wants to develop a new web application. They have a small team of developers and limited resources, but they want to ensure that their application can handle a rapidly growing user base. By building their application using a Cloud Native approach, they can leverage the scalability and resilience of cloud services. They can use containerization to easily deploy and manage their application across different cloud environments, and they can take advantage of serverless computing to optimize costs and performance. This allows them to focus on developing their application without worrying about the underlying infrastructure.

The Core Differences Between Cloud Friendly and Cloud Native

Design and Architecture

One of the key differences between Cloud Friendly and Cloud Native applications lies in their design and architecture. Cloud Friendly applications are typically built on traditional monolithic architectures, which may limit their scalability and flexibility. This means that as the application grows, it may become more difficult to add new features or handle increased traffic. On the other hand, Cloud Native applications embrace microservices architecture, which allows for modular and independent components that can be scaled individually as needed.

This fundamental difference in architecture can have a significant impact on the overall performance and manageability of the application. While Cloud Friendly applications may be easier to transition from existing systems, they may not fully exploit the scalability and agility of the cloud. Cloud Native applications, with their modular design, can take full advantage of cloud resources and scale seamlessly to meet changing demands.

Furthermore, the microservices architecture of Cloud Native applications enables better fault isolation. In the event of a failure in one component, only that specific component is affected, minimizing the impact on the overall system. This fault tolerance is not as prevalent in Cloud Friendly applications, where a failure in one part of the monolithic architecture can potentially bring down the entire system.

Scalability and Performance

Scalability is another area where Cloud Friendly and Cloud Native applications differ. Cloud Native applications are designed for horizontal scalability, meaning that they can handle increasing workloads by adding more instances of components. This allows for greater flexibility in managing traffic spikes and ensures that the application can scale seamlessly as the user base grows. In contrast, Cloud Friendly applications may require manual intervention to scale, relying on traditional scaling techniques that may not be as responsive or efficient.

Performance is closely tied to scalability. Cloud Native applications, with their distributed and modular architecture, are better equipped to handle surges in traffic and offer better responsiveness. The ability to scale individual components independently allows for more efficient resource allocation, ensuring that each part of the application can handle its specific workload effectively. Cloud Friendly applications, while potentially benefiting from the scalability of the cloud, may not achieve the same level of performance optimization due to their monolithic nature.

Moreover, Cloud Native applications can leverage containerization technologies such as Docker and Kubernetes, which provide additional benefits for scalability and performance. Containers allow for the isolation of application components, ensuring that they can be deployed and scaled independently. This level of flexibility and resource efficiency is not easily achievable in Cloud Friendly applications.

Cost Implications

Cost is always a critical consideration for businesses. Cloud Friendly applications often require a lesser upfront investment since they can leverage existing on-premises infrastructure. They also provide the flexibility to gradually migrate to the cloud, allowing businesses to spread the cost over time. However, they may incur higher operational costs in the long run due to limited scalability and the need to manage a mixed infrastructure.

Cloud Native applications, while demanding greater upfront investment in terms of rearchitecting and redeveloping, can offer significant cost savings in the long term. They can take full advantage of cloud automation and scalability features, which can optimize resource utilization and reduce operational costs. The ability to scale horizontally and handle increased workloads efficiently can lead to better cost efficiency in the cloud. However, businesses must carefully consider their budget and resources before committing to the more extensive development efforts required for a Cloud Native approach.

It is also worth noting that the cost implications of Cloud Native applications go beyond infrastructure and operational expenses. The modular nature of these applications allows for faster development cycles and easier maintenance, which can result in reduced development costs over time. Additionally, the scalability and performance benefits of Cloud Native applications can lead to improved user experiences and increased customer satisfaction, ultimately impacting the bottom line of businesses.

Pros and Cons of Cloud Friendly Applications

Advantages of Cloud Friendly Applications

Cloud Friendly applications provide a smoother transition path for businesses looking to migrate to the cloud. They allow for the reuse of existing infrastructure and expertise, minimizing disruption and reducing migration costs. These applications can benefit from certain cloud services, such as storage and virtual machines, without fully committing to the cloud-native paradigm.

Furthermore, Cloud Friendly applications can offer improved fault tolerance and disaster recovery capabilities by leveraging the redundancy of cloud infrastructure. They can also provide better availability as they are not dependent on a single physical location.

Disadvantages of Cloud Friendly Applications

Despite their advantages, Cloud Friendly applications have limitations that need to be considered. Their monolithic architecture can make it challenging to scale individual components and may result in inefficiencies and suboptimal resource utilization. Additionally, Cloud Friendly applications may lack the agility and flexibility required to quickly adapt to evolving business needs, especially in highly dynamic and competitive industries.

Furthermore, the reliance on a mix of on-premises and cloud resources may introduce complexities in managing and securing the application, leading to increased operational overhead.
