With AWS as your cloud platform, you gain access to a vast array of services and resources to build, deploy, and manage cloud native applications effectively. Throughout this blog, we will delve into various aspects of cloud native development with AWS.
What is Cloud Native?
Cloud native development is an approach to software development that leverages the power of cloud computing and embraces the principles of scalability, resilience, and agility. It is centered around building applications specifically designed to run on cloud platforms, such as Amazon Web Services (AWS), and takes full advantage of cloud-native technologies and services.
At its core, cloud native development focuses on developing applications that are modular, scalable, and can be rapidly deployed and managed in a dynamic and distributed cloud environment. It promotes the use of containerization, microservices architecture, and serverless computing to enable developers to build and deploy applications faster, with improved scalability and resilience.
One of the key benefits of cloud native development is the ability to leverage the flexibility and scalability of cloud infrastructure. With cloud providers like AWS, developers have access to a wide range of managed services and tools that simplify the deployment and management of applications, such as container orchestration platforms like Amazon Elastic Kubernetes Service (EKS) and serverless computing platforms like AWS Lambda.
Cloud native development also embraces the principles of DevOps, promoting collaboration between development and operations teams to achieve continuous integration, continuous delivery, and continuous deployment (CI/CD) pipelines. This allows for faster iteration and delivery of software, enabling organizations to respond quickly to changing business needs.
In addition to scalability and agility, cloud native development places a strong emphasis on resiliency and fault tolerance. By leveraging cloud-native services like auto-scaling, load balancing, and fault-tolerant databases, applications can automatically scale to handle increased traffic and recover from failures without impacting the user experience.
Cloud Native Application
A cloud native application is a type of software application specifically designed and built to fully leverage the benefits and capabilities of cloud computing. It is developed using cloud-native principles, technologies, and architectures, enabling it to harness the scalability, flexibility, and resilience offered by cloud platforms.
Key characters of a cloud native application
Microservices Architecture
A cloud native application is typically built using a microservices architectural pattern. It is composed of small, loosely coupled, and independently deployable services that work together to form the complete application. Each microservice focuses on a specific business capability and can be developed, deployed, and scaled independently.
Containers
Cloud native applications often use containerization technology, such as Docker, to package and deploy individual microservices. Containers provide a lightweight and isolated runtime environment for the application, enabling easy deployment and scalability across different cloud environments.
Scalability and Elasticity
Cloud native applications are designed to scale horizontally, meaning they can handle increasing workloads by adding more instances of the microservices as needed. They can automatically scale up or down based on demand, ensuring optimal resource utilization and responsiveness.
DevOps Practices
Cloud native applications embrace DevOps principles and practices, promoting collaboration between development and operations teams. This includes automated testing, continuous integration, continuous deployment (CI/CD) pipelines, infrastructure as code, and monitoring and observability.
Resilience and Fault Tolerance
Cloud native applications are designed to be resilient in the face of failures and disruptions. They leverage the inherent fault tolerance capabilities of cloud platforms, such as automatic scaling, load balancing, and self-healing mechanisms, to ensure high availability and reliability.
Platform Independence
Cloud native applications are designed to be platform-agnostic and can be deployed on various cloud platforms or in hybrid cloud environments. This allows organizations to take advantage of multiple cloud providers or migrate their applications seamlessly across different environments.
