Cloud native application development is an essential approach where applications are built to live and breathe in the cloud. Research suggests that by 2022, about 95 percent of all applications developed internally by organizations are expected to be deployed on the cloud.
Driving value across industries is a motto of Visionet India. The company empowers global industries with high-RoI intelligent solutions. It empowers clients with world-class digital solutions using cutting-edge technologies.
Alok Bansal, MD and CEO, Visionet India, tells us more. Excerpts from an interview:
DQ: The obvious question: why go cloud native?
Alok Bansal: A successful industry aims at providing their customers with extraordinary interactions and experiences with incessant modernization and continuous delivery. Cloud native is a way to increase the velocity of industries, and structure in a way that utilizes automation to the fullest and increases scalability of newer technologies.
In modern cloud architecture, unravelling the subsequent levels of cloud benefits will enable our businesses to use micro services, scalable containers, DevOps and elastic cloud-computing resources to maximize benefits.
DQ: What are the essential elements of cloud native application development?
Alok Bansal: Cloud-native applications are positioned on infrastructure that extracts underlying compute, storage and network primitives that is different from traditional manual applications. The essential elements of cloud native application development are:
Microservices architectures: This architecture style is totally different from the current monolithic style. It is a methodology that develops a solitary application as a suite of small services, running its own process by communicating with lightweight mechanisms, like HTTP resource as the API.
The microservices architecture are built to improve industry capability by deploying fully automated machinery. The centralized management of this architecture is minute and its programming can be written in different languages using various data storage technologies.
Container orchestration: Docker containers along with microservises will run in different container written in various languages, while being deployed independently. These containers are portable and can operate in any environment removing the risk of friction between diverse frameworks.
Post the placement of microservices on Docker containers, an orchestrator is required to manage the cluster so that they make sense as an application. Orchestrators like Google Kubernetes, Docker Swarm, etc., can be used.
Automated deployments and monitoring: Cloud native has continuously flowing features that are fully automated as opposed to traditional waterfall models that require sequence of stages. With microservices, containerization and automated deployment, the servers require continuous monitoring and tracking for cloud native apps.
DQ: There is the need for speed. How are you factoring inthe rise of open source?
Alok Bansal: With digital transformation and re-engineered applications, there is a dire need for greater clarity and speed in businesses. Cloud- native as an open source framework can run on any platform with micro-services–based architectures that bring on-demand elasticity, increased uptime and reduced costs. This essential quality of omnipresence meets the dream technological qualities of enterprises.
Cloud native applications organize services that are highly scalable and trustworthy. As an open source application, it establishes control over codes and servers that can be examined to verify its adherence to claims like security policies and government regulations. In 2020, companies don’t want proprietary technologies that become obsolete if they age poorly with time, so open source Cloud- native provides assurance that it can be internally fixed, upgraded and adapted with changing intervals of time.
Advanced cloud-native applications, such as serverless operation, lets businesses run dynamic workloads with compute time in milliseconds. This is the ultimate testament of cloud-native as an open-source high speed application.
DQ: What are the advantages of cloud-native technologies?
Alok Bansal: There are many advantages. Some of them are:
Superior customer experiences: To build an engaging customer-employee experience, API-based integration is predominant. Enterprises benefit from a technological world where traditional models are being challenged with mobile applications like Cloud-native. With its improved speed, flexibility and agility, it improves customer experiences manifold.
Automated resource management- Cloud-native applications facilitate on-demand, are self – servicing and deliver automated provisions for resource management. This enables industries-critical applications to run effortlessly with on-demand distribution of resources directly from the application. Cloud-native apps can bring back the resources to the pool after execution of given task.
Reduced cost through containerization and cloud principles: Use of containers makes the management and security of applications easy and away from infrastructure that previously used to support them. Containers along with an open source model, brings down the cost.
DQ: How has cloud native changed the work of developers?
Alok Bansal: Cloud-native is developed with the best of computing languages and frameworks that are each suited for a specific functionality. These applications are polyglot, making developers invest time in building a real-time streaming service based on WebSockets whilst choosing Python or Flask as the API. This approach helps the developers with choosing the best suited language required for a specific task.
Services on the cloud-native app are loosely coupled microservices that exist independent of each other and it allows developers to treat each architecture as an independent entity. With this decoupling, the focus shifts to the core functionality of each service that delivers fine-tuned functionality allowing independent ownership of the developer.
Every service of the Cloud-native application goes through an individual life cycle, which are managed by the developers through DevOps process. Finally, these applications support the governance model that are distinct through given set of policies such as CPU, storage units and networks, and develops in each segment have ownership of their own resources.
DQ: How can cloud-native software run almost anywhere?
Alok Bansal: There are two words associated with cloud-native technology: anytime and anywhere! When industries are free from static, legacy data centers, efficiency is improved robustly.
The increased elasticity with cloud-native applications can allow employees to leverage information from anyplace anytime thus giving them benefits of increased capability and collaboration with customers in different locations, different time zones, etc.
Cloud-native is an open source application that can run on any server by utilizing Big Data analytics, flexible storage and actionable intelligence. The microservices structure tramples the huge monolithic system in terms of adaptability, scalability and adaptation. Along with that the containerization helps industries to access cloud-native from any server at any time.
