The Cloud Native Methodology in Software Engineering

What is Native Cloud? The Contemporary Approach to Build Software

Nallas Cloud Engineering experts says, Cloud-native computing leverages several contemporary software development approaches, such as microservices, containers, CI/CD, agile processes, and DevOps.   

The phrase “cloud-native computing” has arisen as an umbrella term for the numerous tools and approaches needed by software developers to design, deploy, and manage contemporary software applications on cloud infrastructure. This article defines the word, surveys the cloud-native ecosystem, and identifies the benefits and dangers of adopting a cloud-native architecture. 

Cloud-Native Definition

Cloud-native is a contemporary method for developing and deploying software applications that takes use of the elasticity, scalability, and resiliency of cloud computing. In contrast to conventional architectures designed for on-premises data centers, cloud-native covers the different tools and approaches used by software developers to create applications for the public cloud.   

The cloud-native method to developing and operating software was pioneered by a set of “born in the cloud” firms, such as streaming giants Netflix and Spotify, ride-hailing startup Uber, and lodging booking site Airbnb. The cloud-native strategy has now been adopted by numerous businesses seeking digital agility and disruptive competitive advantage comparable to their own.   

The Cloud Native Computing Foundation (CNCF) defines cloud-native a little more narrowly, focused on application containerization — where programs are divided into microservices and packed in lightweight containers in order to be deployed and coordinated across several servers. 

“Cloud-native technologies enable enterprises to design and deploy scalable applications in contemporary, dynamic settings such as public, private, and hybrid clouds,” as stated by the Cloud Native Computing Foundation. 

Cloud-native application development often combines DevOps and agile approach with microservices, cloud platforms, containers, Kubernetes, immutable infrastructure, declarative APIs, and continuous delivery technologies. 

Cloud-Native Terrain

As a result of this transition in prevalent software development methods, a new ecosystem of largely open-source tools has emerged. This ecology is represented by an interactive graphic maintained by the CNCF. 

Understanding the four levels of cloud-native computing is essential. 

  • The application definition and development layer. The cloud-native stack’s top layer focuses on the tools used by developers to construct applications, such as databases, messaging systems, container images, and continuous integration/continuous delivery (CI/CD) pipelines. 
  • The layer of provisioning. The provisioning layer of the cloud-native stack consists of everything necessary to construct and secure the environment in which an application will operate, preferably in a repeatable manner. This often entails treating infrastructure as code, storing images in a repository, automating builds, and handling application security requirements with vulnerability screening, key and policy management, and authentication tools in the cloud-native world. 
  • This is the runtime layer. The runtime layer encompasses everything related to the execution of a cloud-native application, such as the container runtime, which is often still Docker, as well as storage and networking. 
  • The management and orchestration layer. The orchestration and management layer combines the orchestration and scheduling technologies necessary to deploy, manage, and scale containerized applications. This often includes Kubernetes, service discovery, service proxy, API gateway, and service mesh. 

Outside of these levels, observability principles must also be implemented so that all these services may be successfully monitored. To facilitate developer adoption, some businesses choose to consolidate their stack into an internal self-service developer platform or to acquire an opinionated platform as a service (PaaS) from a vendor.

The Benefits Of Cloud-native Architectures Over On-premises Ones

Cloud-native application development requires a significantly different design than conventional business apps, which generally operate on-premises. Here are many important distinctions and benefits between cloud-native apps and conventional app development methodologies.   

  • Languages. Typically, standard programming languages, such as C/C++, C#, and corporate Java, are used to develop on-premises applications. The majority of cloud-native applications are developed in web-centric languages such as HTML, CSS, Java, JavaScript,.NET, Go, Node.js, PHP, Python, and Ruby. Working with current languages and platforms may assist your firm in recruiting the most talented developers.  
  • Updatability. Cloud-native applications are designed to be highly available, robust, and routinely upgradable, while on-premises systems are normally updated using a waterfall technique once or twice a year. The upgradability of cloud-native computing allows development teams to concentrate on their competitive edge and provide new features to clients more often than previously.  
  • Elasticity. Typically, cloud-native apps use the flexibility of the cloud by adjusting consumption based on demand, while an on-premises application would need the actual installation of extra hardware to grow successfully. This has theoretical financial implications, since the cloud enables you to pay just for what you need and prevent overprovisioning your own equipment.  
  • Multitenancy. A cloud-native application has no difficulty operating in a virtualized environment and sharing resources with other apps utilizing a multitenant architecture. This clearly increases the efficiency of development teams.  
  • Downtime. Due to the size and geographical dispersion of data centers maintained by hyper scale cloud suppliers, the cloud provides higher redundancy, allowing outages to be better controlled by instantly routing traffic to another location and avoiding expensive downtime.
  • Automation. Cloud-native approaches provide developers with a plethora of automation options, allowing them to create once and move on to more critical problems. 
  • Stateless. Cloud-native apps are often stateless, since they do not retain stored data from one session to the next. This approach makes it possible to simply expand across numerous servers, cache more efficiently for a speed increase, utilize less storage, and prevent vendor lock-in by not being tied to a single server.

Nallas Cloud Engineering Services can help you reap the above benefits. We can help your business transition smoothly to cloud. 

Cloud-Native Difficulties

Attempting to migrate an existing on-premises program to the cloud without architectural problems is a typical error, but reengineering anything for the cloud is also a substantial engineering task.   

Finding the proper skill set, adjusting to a cloud-centric security model, and managing the fluctuating cost profile of a cloud environment continue to be significant obstacles for enterprises seeking to adopt a cloud-native architecture. 

Nonetheless, developers should seek to adopt cloud-native as an organizational paradigm, either by creating new cloud-based apps or by decomposing existing monolithic programs into microservices that are more suited to a cloud environment.
