Cloud-native apps enable fast adaptation and scalability, unlike traditional software architecture. And, it’s more than just shifting existing software to the cloud.

Cloud-native deploys technologies such as containers, Kubernetes, immutable infrastructure, and microservices to build scalable applications designed to run in the cloud.

MarketsandMarkets reports the global cloud-native applications market is estimated to reach $17.0 billion by 2028, growing at a compound annual growth rate (CAGR) of 23.7% from 2023 to 2028. 

Cloud computing has completely revolutionized how we build, deploy, and scale applications. And cloud-native is the key to unlocking its full potential. It’s not just about transferring existing apps to the cloud; it’s about completely rethinking software from the ground up to fully adopt the cloud’s inherent agility, elasticity, and resilience.

In this blog, we take you through the intricacies of cloud-native to help you navigate the cloud-computing landscape.

Cloud-native: The Essential Cloud-native Elements

  • Microservices: Cloud-native breaks down applications into small, independent services, each focused on a specific task, making them quicker to develop, deploy, and update.
  • Containers: Think of these as portable shipping crates for your code. Containers bundle everything an application needs to run – code, libraries, and its operating system – making them efficient and secure across any cloud environment.
  • Kubernetes: Kubernetes automates container deployment, scaling, and communication, keeping your entire app ecosystem running smoothly.
  • DevOps: It’s all about breaking down the walls between development and operations. Cloud-native embraces DevOps principles, encouraging collaboration and automation to build, test, and deploy software rapidly.

Benefits of Cloud-native

With the changing dynamics of the business marketing landscape, traditional software approaches can’t keep pace. Thanks to cloud-native applications crafted specifically for the cloud environment, the scenario is changing for the better.

This innovative architecture delivers tangible benefits for forward-thinking organizations:

  1. Optimized Cost Management: Cloud orchestration tools like Kubernetes dynamically allocate resources, eliminating overprovisioning and ensuring optimal cost efficiency.
  2. Accelerated Time to Market: Deploy updates and features rapidly with microservices-based architecture, enabling your team to respond swiftly to market changes and opportunities.
  3. Enhanced Business Alignment: Cloud-native applications adapt seamlessly to evolving business needs, ensuring your technology roadmap and strategic objectives remain in sync.
  4. Reduced Operational Burden: Automate routine tasks and simplify infrastructure management, freeing up your IT team to focus on strategic initiatives.

Navigating 6 Cloud-Native Challenges

Cloud-native development presents unique challenges for developers, operations teams, and organizations. 

Here’s a closer look at the roadblocks you might encounter:

  1. Multi-Cloud Complexity: Managing applications across multiple cloud providers introduces complexities in dependency management, data silos, and vendor lock-in. This can lead to increased costs, operational overhead, and slower delivery times.
  2. Scaling Challenges: Efficiently scaling applications up and down to meet fluctuating demand can be difficult in a cloud-native environment. Inadequate planning and automation can result in performance bottlenecks, wasted resources, and higher cloud bills.
  3. Microservices Management: As the number of microservices grows, maintaining service orchestration, communication, and debugging becomes increasingly complex. Without proper organization and monitoring tools, troubleshooting issues can be time-consuming and frustrating.
  4. Ephemeral Infrastructure: Debugging problems in containerized environments can be challenging due to the ephemeral nature of containers. Effective logging, tracing, and observability solutions are crucial for identifying and resolving issues before they impact users.
  5. Cost Optimization: The pay-as-you-go model of the cloud can lead to significant expenditure if not managed effectively. Resource optimization, rightsizing instances, and automation are essential for controlling costs and maximizing ROI.
  6. Integration Hurdles: Ensuring seamless integration between diverse services can be difficult due to incompatible APIs, data silos, and communication protocols. Standardized APIs, event-driven architectures, and robust communication protocols are key to overcoming these hurdles.

Cloud-Native: The Three Approaches in Brief

1. Multi-Cloud: Managing services across different cloud providers like AWS and Azure. 
Pros: Redundancy, cost optimization, avoid vendor lock-in.

Cons: Complexity, vendor-specific tools.

2. Hybrid Cloud: Blending your data center with public cloud services.

Pros: More control over sensitive data, leverage on-premises resources. 

Cons: Less agility, and complex management.

3. Serverless Computing: Focus on code, and let the cloud handle infrastructure. 

Pros: Highly scalable, low maintenance, pay-per-use. 

Cons: Vendor lock-in, limited control, potentially higher costs.

What Cloud-Native Approach Should You Choose?

  • Multi-cloud for cost and resilience.
  • Hybrid for security and control.
  • Serverless for agility and simplicity.

Is the Shift Necessary?

Yes. 

The advantages of cloud-native applications are quite apparent. These applications can scale with ease as their functions are separated into microservices, allowing individual management. Additionally, cloud-native apps can run in a highly distributed manner, maintaining independence and allocating resources based on the application’s needs, as they are agnostic to their cloud infrastructure.

Cloud-native applications have become an essential tool to enhance business strategy and value. They can offer a consistent experience across private, public, and hybrid clouds, allowing your organization to take full advantage of cloud computing. These applications are responsive, reliable, and highly scalable, which reduces risk and ensures seamless operations.
