The cloud computing paradigm supplies IT services where resources are made available as a service online. With the help of this approach, companies can consume resources as needed without having to finance and maintain their infrastructure. The three basic kinds of cloud services are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

Customers have access to virtual computers, storage, and networking thanks to IaaS. Customers who use PaaS have access to a platform for developing, deploying, and running applications. Customers get access to software programs through SaaS that they can utilize online.

The main benefit of XaaS (anything as a service) is its scalability. Since companies only pay for the infrastructure they use, they can scale up or down as necessary. This makes it perfect for organizations with erratic or variable demand and gives lean, adaptable enterprises a foundation to build to satisfy market demands. 

Today, we’ll explore what makes cloud-native applications a fantastic solution and discuss some potential dangers and challenges we may encounter while moving our company to the cloud.


An Explanation of Cloud-Native Applications

An application that is built specifically to run on the cloud is referred to as cloud-native. It utilizes the microservices architecture and the cloud computing concept. Scalable, fault-tolerant, and simple to deploy are all characteristics of cloud-native apps. They frequently run on common hardware and are created using open-source technology. Cloud-native apps are created using microservices, put into containers, and managed with orchestration tools, to put it simply.

A larger application is created by a collection of tiny, autonomous services known as microservices. Each microservice can be launched individually and has a distinct function. One microservice might handle user authentication, and another might manage product catalogs. Microservices are frequently created utilizing many programming languages and platforms. They use APIs to communicate with one another. On the downside, microservices need additional communication between services and added complexity.

The software can be packaged in containers to make its deployment across many environments simple and reliable. A popular container technology like Docker, for example, allows developers to execute their programs in containers on any server that supports Docker.

Microservice deployment is managed and automated using orchestration technologies. The lifespan of microservices can be managed using orchestration tools, which can also be used to start, halt, and scale services up or down in response to changes in demand. As an illustration, the orchestration tool Kubernetes can be used to control the deployment of microservices on a server cluster.


How to Create a Cloud-Native App

When creating a cloud-native application, there are several things to consider, such as how the application will be scaled, deployed, and monitored. Along with considering the platform’s capabilities and the demands of its consumers, developers must also select the appropriate tools and technologies for their applications.

A few general pointers

Use containers and microservices: Cloud-native apps require these essential building blocks. Your application can be made more manageable and scalable by being divided into separate, independent pieces.

Automate all processes: Another crucial component of cloud-native apps is automation. You may save time and money by automating processes like scaling and deployments.

Use a declarative strategy: In a declarative strategy, you specify your intended state and let the system handle the specifics. In contrast, with an imperative strategy, each action must be taken expressly stated. Declarative strategies are frequently more durable and simpler to keep up with over time.

Be driven by observability: Monitoring needs to be included in cloud-native applications from the ground up. Ensure you have complete visibility into your application to spot and address issues as they arise.

Make your applications available: Use CD/CD pipelines to automatically push new versions of your code to production servers with the least amount of effort on your or your team’s part.


The Advantages of Cloud Native

The following are just a few of the many advantages of cloud-native applications:

Enhanced agility: Cloud-native applications are made to be deployed and updated more quickly than traditional apps, which can assist businesses in being more responsive to market changes or client needs.

Improved scalability: Cloud-native apps are better able to handle demand spikes without overtaxing their resources or crashing than traditional apps.

Cost savings: Cloud-native apps can aid organizations in reducing infrastructure and operational costs because they are made to be more resource-efficient.

Enhanced security: Cloud-native apps can benefit from the security features provided by cloud providers, such as user authentication and data encryption.

Better performance: Because cloud-native apps are built to take advantage of the cloud’s high-performance computing capabilities, they can offer a better user experience than conventional apps. Collaboration among team members has improved thanks to cloud-native apps, which team members can access and use from anywhere in the world.

Benefits for the environment: Cloud-native apps can aid in lowering an organization’s carbon footprint because they are created to be more resource-efficient.


The Dangers of Going Cloud Native

The risks of going cloud-native are numerous and can be broadly classified as follows:

Data loss or corruption, service outages, and security breaches are all examples of technical risks.

  1. Organizational risks include the possibility of disrupting business processes.
  2. Conflicts between traditional and cloud-native organizations and the need for new skills and training pose cultural risks.
  3. Financial risks include increased costs, lower margins, and the need to reinvest in legacy systems.
  4. The possibility of new compliance requirements and the need to adapt to new regulations are examples of regulatory risks.


The Future of Apps Is in the Cloud

To not be enthused by the implications of cloud-native apps requires a stoic individual. It is extraordinary to have technology that behaves nearly like a living entity, evolving and responding to the environment. Monolithic architectures will always have a place, but larger products must be more flexible and adaptable to the always-shifting market.

Cloud-native solutions can make your project stand out from the competition by offering a more dependable system that can easily handle various processing levels. Of course, that depends on being ready from the start and aware of the challenges of such a technology.
