Cloud-Native technology is the most efficient technology for the continuous creation and operation of the world’s largest cloud applications. Cloud computing is an approach to building and running applications that take advantage of the cloud computing model. Native cloud applications are a collection of small, independent, and loosely coupled services. These are applications built using a cloud computing model to improve quality, increase speed, and flexibility while reducing deployment risk. It is an approach that focuses on how applications are built, deployed, and managed. No wonder why implementing cloud-based network traffic management in cloud-based applications has been a pressing challenge!
When called “Cloud Native,” an application clearly states that it is designed to provide automatic, consistent development and management across different clouds, whether private, public, or hybrid. A cloud application uses a set of tools that make it easy to orchestrate and manage application services. These services are individually deployed as containers and connected via API. The containers are then managed by the container scheduler, which is responsible for managing where and when the container should be provisioned in the application.
Cloud-Native Development Architecture
Organizations are adopting the cloud computing model to expand application scalability and availability. These benefits are achieved by providing resources on demand and automating the application lifecycle from development to production. But to take full advantage of these benefits, a new type of development is required. Cloud-Native application development meets this requirement. It is an approach to rapidly building and updating applications while continuously improving quality by reducing risk. Specifically, it is an approach to building and running flexible, scalable, and resilient applications anywhere – be it public, private, or hybrid clouds. Cloud-Native applications are designed to be portable across different deployment environments: public, private, or hybrid cloud. DevOps and CI / CD are used to automate the creation, testing, and deployment of services on a production network. Let us discuss the development processes below:
A microservices architecture structures an application to collect independent and loosely coupled services to realize business opportunities. The microservices should be deployed, scaled, and updated independently of each other. It facilitates continuous provisioning and continuous delivery of large and complex applications.
Containers are a form of virtualization. The OS instance is split into several isolated containers with individual writable file systems and resource quotas. Thus, containers actually use virtualization at the operating system level. Each microservice is usually deployed in a separate container; however, multiple microservices can be deployed in each container based on application and performance requirements.
Continuous delivery offering
The adoption of continuous delivery has revolutionized the speed of time to market. This makes releases simple and reliable, allowing organizations to release more frequently and with less risk. It’s all about getting your custom app customization ready for release without even waiting to merge it with other changes in the release. Using continuous delivery provides immediate feedback from end-users to developers.
Empowering DevOps Best Practices
DevOps integrates development and operations into a single IT value stream through the use of agile and cost-effective software development practices. This enables organizations to leverage continuous integration and continuous delivery services to create, test, and deploy software faster and more iteratively. Thus, we can say that cloud technologies provide the basic building blocks for creating applications that achieve the goal of reducing operating costs by simplifying and automating network operations, enabling faster time-to-market services and deployment across a wide range of cloud environments.
Why Cloud-Native Networks?
View cloud networks as a revolution in network design and architecture. Similar to cloud application development, cloud networks also run their services, such as security audits, route calculation, and policy enforcement, on a platform that takes full advantage of cloud attributes. Proprietary devices are not used, which changes the technical and operational characteristics of corporate networks. The platform used for such networks has a multi-user design, runs on standard servers, and can provide breakthrough performance that was previously only possible with individual hardware use.
Common myths about cloud-native networks
The cloud is not just about transferring software or placing a device in the cloud. In fact, it is a network built from scratch with a cloud service. Cloud networks do not follow the legacy process of traditional network service providers. Instead, they avoid overhead and significantly impact the size of the enterprise, which can be better understood by looking at the five attributes below.
Cloud network service attributes
The attributes described below are important factors that must be respected if the vendor’s software and networking platform are to be treated as cloud-based:
Scalability is one of the most important characteristics of cloud networks, as well as cloud applications. They have no scaling limits. The software stack is designed to use additional computing resources, memory, network resources, and storage. New traffic loads or requirements can be easily adapted to the network platform.
Efficiency is another attribute that cloud networking services greatly contribute to. Cloud networking is designed to deliver high network quality and performance at a low cost. Third-party license fees, as well as nominal support costs, are excluded due to platform ownership. The cost of building and maintaining physical transmission networks is eliminated with an intelligent software overlay that continuously monitors the main network providers and selects the most optimal one for each transmitted packet. The result is a carrier-grade network at unbeatable price and performance.
Multi-tenancy is an abstraction of the underlying infrastructure for providing each client with a private network experience. The network provider is responsible for maintaining and scaling the network infrastructure. Like any other cloud storage and computing, cloud networks also have no idle devices. Multi-tenancy allows you to maximize the underlying network infrastructure.
VNF is implemented as code monoliths, which adds to the complexity.
Cloud networks play a key role, especially when it comes to cloud environments. Cloud networks have revolutionized network design and architecture. These are networks built from the ground up based on cloud services. The advent of Cloud-Native Networking makes the network one of the most important and visible roles in the success of cloud applications.
