class=\"ez-toc-section\" id=\"Defining_Cloud_Native_Applications\"><\/span>Defining Cloud Native Applications<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>A cloud native application is architected to take full advantage of on-demand, elastic resources provided by modern cloud platforms like AWS, Google Cloud, and Azure. Here are some of the key attributes of a cloud native app:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Built as microservices<\/strong> &#8211; The app is broken down into independently deployable services versus a monolithic architecture. This enables frequent updates and resilience.<\/li>\n\n\n\n<li><strong>Managed through APIs<\/strong> &#8211; All services expose APIs that are used to communicate between components. This facilitates loosely coupled architecture.<\/li>\n\n\n\n<li><strong>Packaged in containers<\/strong> &#8211; Components are packaged in lightweight, portable containers (e.g. Docker) that can be deployed across environments.<\/li>\n\n\n\n<li><strong>Orchestrated dynamically<\/strong> &#8211; Containers are actively managed and orchestrated by Kubernetes or similar platforms. This enables automation and scaling.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Key_Characteristics_of_Cloud-Native_Applications\"><\/span>Key Characteristics of Cloud-Native Applications<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Cloud-native applications are designed to fully leverage the capabilities of cloud environments. They exhibit several key characteristics, including:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Microservices Architecture:<\/strong> Cloud-native applications are often built as a collection of independent services, each serving a specific business function. This microservices architecture enhances agility, scalability, and ease of maintenance. Furthermore, centralized gateways handle security, traffic management, and governance for all microservices APIs.<\/li>\n\n\n\n<li><strong>Containerization:<\/strong> Containers encapsulate an application and its dependencies, ensuring consistency across various environments. Popular containerization tools like Docker have become integral to cloud-native development.<\/li>\n\n\n\n<li><strong>Dynamic Environments:<\/strong> Cloud-native applications thrive in dynamic environments, scaling seamlessly based on demand. This scalability is achieved through container orchestration tools like Kubernetes, which automate the deployment, scaling, and management of containerized applications.<\/li>\n\n\n\n<li><strong>Continuous Delivery:<\/strong> Embracing DevOps principles, cloud-native development emphasizes continuous integration and continuous delivery (CI\/CD) pipelines. This results in faster delivery of updates and features, enhancing the overall development process.<\/li>\n\n\n\n<li><strong>Designed for resilience<\/strong> &#8211; The application is designed for failure with features like circuit breakers. It uses replication and redundancy to achieve high availability.<\/li>\n\n\n\n<li><strong>Optimized for cloud<\/strong> &#8211; The app is designed to leverage cloud-based resources on-demand, such as object storage, load balancing, and auto-scaling.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Cloud-Native_Architecture\"><\/span><strong>Cloud-Native Architecture<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<h4 class=\"wp-block-heading\">Building Blocks of Cloud-Native Architecture<\/h4>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Computing Resources:<\/strong> Cloud-native applications leverage computing resources provided by cloud providers, allowing for on-demand scalability and flexibility. Apps natively leverage managed cloud services like storage, load balancing, app hosting, messaging, etc.<\/li>\n\n\n\n<li><strong>Service Mesh:<\/strong> A service mesh enhances communication between microservices, providing features like load balancing, service discovery, and fault tolerance. Tools like Istio are commonly used to implement service meshes.<\/li>\n\n\n\n<li><strong>Cloud Platform:<\/strong> The underlying cloud platform serves as the foundation for cloud-native applications. Public cloud providers like AWS, Azure, and Google Cloud offer a range of services and resources to facilitate cloud-native development.<\/li>\n\n\n\n<li><strong>Hybrid Clouds and Private Clouds:<\/strong> Cloud-native applications can be designed to run in hybrid or private cloud environments, providing organizations with flexibility in choosing where and how to deploy their applications.<\/li>\n\n\n\n<li><strong>Automation &#8211; <\/strong>Infrastructure as code (IaC) is used to provision infrastructure. IaC uses declarative configuration and deploys infrastructure automatically &#8211; no manual changes. Additionally, automated build, test, and deployment pipelines enable frequent, rapid updates.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Tools_for_Cloud-Native_Application_Development\"><\/span><strong>Tools for Cloud-Native Application Development<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Container_Orchestration_Tools\"><\/span><strong>Container Orchestration Tools<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong><a href=\"https:\/\/kubernetes.io\/\" target=\"_blank\" rel=\"noreferrer noopener\">Kubernetes<\/a>:<\/strong> A robust and widely adopted container orchestration platform that automates the deployment, scaling, and management of containerized applications.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/www.docker.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">Docker<\/a>:<\/strong> A popular containerization tool that simplifies packaging applications and their dependencies into containers.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"CICD_Tools\"><\/span><strong>CI\/CD Tools<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.jenkins.io\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Jenkins<\/strong><\/a><strong>:<\/strong> An open-source automation server that supports building, testing, and deploying code changes.<\/li>\n\n\n\n<li><a href=\"https:\/\/docs.gitlab.com\/ee\/ci\/quick_start\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>GitLab CI\/CD<\/strong><\/a><strong>:<\/strong> Integrated CI\/CD capabilities provided by GitLab for version control and continuous integration.<\/li>\n\n\n\n<li><a href=\"https:\/\/learn.microsoft.com\/en-us\/azure\/devops\/?view=azure-devops\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Azure DevOps<\/strong><\/a>: Microsoft&#8217;s Azure is a powerful CI\/CD tool that integrates with its native cloud based services and on-premises infrastructure. <\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Service_Mesh_Tools\"><\/span><strong>Service Mesh Tools<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong><a href=\"https:\/\/istio.io\/latest\/about\/service-mesh\/\" target=\"_blank\" rel=\"noreferrer noopener\">Istio<\/a>:<\/strong> An open-source service mesh platform that facilitates communication between microservices.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/linkerd.io\/\" target=\"_blank\" rel=\"noreferrer noopener\">Linkerd<\/a>:<\/strong> A lightweight service mesh designed for ease of use and simplicity.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Role_of_the_Cloud_Native_Computing_Foundation_CNCF\"><\/span><strong>Role of the Cloud Native Computing Foundation (CNCF)<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The <a href=\"https:\/\/www.cncf.io\/\" target=\"_blank\" rel=\"noreferrer noopener\">Cloud Native Computing Foundation<\/a> (CNCF) is a vendor-neutral organization that promotes cloud native open source technologies like Kubernetes and related projects.
