Cloud-native applications development is an approach to develop, build and ship applications that takes the advantages of modern Cloud computing services. Cloud-Native Applications are applications that natively utilize services and infrastructure provided by Cloud computing providers, such as Amazon Web Services (AWS) or Google Cloud Platform (GCP). Various servers and databases distributed across many regions.
Cloud-Native Applications mainly built as Microservices, which is a modern architecture to build software. Public and Private Clouds used for modern Cloud-Native applications. The best part is that developers get unlimited computing power, on-demand compute resources, also application frameworks and services for developers building Cloud-native applications. It helps in turning new ideas and solutions to the market with high velocity. Learn more about Three Rs of Security in this insight.

Cloud-Native applications are loosely coupled, dynamically deployed and managed using various services on Cloud. They are independent of underlying hardware and software, which makes Cloud-Native applications to be portable. Modern practices are used to build Cloud-Native applications, such as DevOps, Agile methodology, Cloud platforms (AWS, GCP, Azure), Microservices, Containers (like Docker, Kubernetes), and CI/CD pipelines.
How Cloud-Native Services Work?
Building and managing Cloud-Native applications automate and uses the concepts of DevOps, Continuous Deployment, Microservices, and deploying Microservices in containers. Microservices is a modern architecture which allows the development of the application as a set of tiny services; each service has its business logic, runs in its isolated process and communicates with other services via HTTP REST API endpoints. Each Microservice is usually deployed, scaled, and managed independently of other Microservices which constitutes an application. Often, it happens in an automated fashion, which enables frequent updates in batches to production.
It also helps in getting fast feedbacks and quick fixes to bugs. Containers usually manage all Microservices as distinct independent services, Docker and Kubernetes come into the picture. Containers allow computing, memory, and networking resources for different Microservices. VMs were suitable for monolith applications, but in the case of 10s or 1000s of different Microservices, Containerization is the best way to deploy and manage them. Containers are lightweight and provide the own isolation for packaging Microservices into single units. The whole components process of building and running modern Cloud-Native applications includes -
It is the base which provides all computing resources for applications.
Modern public Cloud computing services as well Private Cloud provides all the services to run, scale, manage all Microservices.
Provisioning the infrastructure
Tools to provide the infrastructure.
Tools such as Terraform, Ansible helps in this process.
Services provided by Cloud computing companies to architect an Infrastructure.

Why Cloud-Native Engineering Matters?
Following are the reasons why Cloud-Native application development matters -
It provides Microservices Architecture
Microservices architecture has tremendous benefits such as loosely coupled services, scale-out, faster release cycles, lower complexity as it's divided across many teams.
Provides all advantage of Cloud
It helps in delivering applications at a faster rate, as per customer needs. Cloud provides all the flexibility and resilience of these modern applications.
All communication is API-Based, which is quick and transparent
Services communicate via lightweight APIs which help in reducing the complexity and extra overhead of deploying scaling applications. All communication happens via service interface calls over the network. There is no risk of direct linking of services, shared memory models used in Monolith.
What are the benefits of enabling Cloud Native Computing?
Whole underlying Infrastructure is Container-Based which has tremendous benefits.
Cloud-Native applications deployed in containers, which gives application portability across various environments and infrastructure, including Public or Private Cloud.
Containers use OS-virtualization to distribute available compute resources among different. applications while also making sure that applications are secure and complete isolation between them.
Modern DevOps Processes adopted which deliver software at high velocity.
Cloud-Native Application uses devops process with Continuous Deployment and Agile principles which focus on developing and delivering applications in collaboration with various teams.
Building and managing cloud-native applications is being fascinated by many enterprises to deliver flawless customer experience and to faster the execution of their operations. Kindly take below steps before you proceed further onto this.
