As we all know, in today’s corporate world, application development has slowly become a significant key to business success. The success of applications developed and used by business organizations can very well be the factor that makes or breaks them. The pocket flip phones were probably the first to introduce the concept of apps with pretty basic ones such as a calculator, notepad, address book, calendar, and probably an e-mail app for the really expensive ones. However, in today’s smartphone era, applications have taken over the globe as we know it. We practically have an application for anything and everything. Games, Education, Lifestyle, Food-delivery, Literature, Travel, Movies, Music, Navigation, Health and Fitness, Shopping, Bookings- you name service and you’ll have an app for it.
With all these apps and the growing market for them, the tech giants got creative with their methods of application development as well. They introduced a variety of methods to develop modern high-quality apps while also significantly cutting costs to ensure a significant margin of profits. One such method is Cloud Native Development.
Cloud Native Development was designed as a concept for developing and running applications that capitalize on the distributed computing offered by a cloud computing model. It helps you run the application in any dynamic, modern environment such as private, public, or hybrid clouds. The microservice architecture of cloud-native apps allows them to allocate resources efficiently to each service used by the application. This makes the application flexible and easily adaptable to a cloud architecture.
Any cloud-native application is brought into production keeping in mind 5 critical elements. They are as follows:
Cloud-native apps follow the Microservices approach, which deconstructs a single application into multiple functional components, each executing separately. This deconstruction allows each of these functional components to be deployed and updated without affecting the other parts of the application. This approach was pioneered by the video streaming giant Netflix.
API (Application Programming Interface) is used to handle communication in microservices-based applications. An API offers the user an interface that they can call by way of a standardized protocol. That makes it relatively easy for external callers to know how to format a service request, whether it is from another service located on the same LAN or one located across the internet.
As the environment of microservices-based applications is partitioned, code changes are segregated into a specific executable, leaving most of an application unchanged even after updating. This makes the process of rolling out code changes easier, simpler, and less risky.
The basic aim of DevOps is the substitution of automation for manual processes across the application life cycle. With DevOps, an organization tries to reduce the time between when developers write the code and when you place it into production, as much as possible.
Most organizations wait till just after deployment to conduct QA (Quality Assurance) testing. However, it is completely unacceptable as Quality Assurance, in any case, can’t be an afterthought. Testing should be moved to be an earlier part of the development lifecycle. This way, it becomes a core part of the development process. Conducting the QA testing process earlier also allows the developers to identify and address any issues in the early stages of the development process, which in turn avoids a panic response and application outages.
Some advantages of adopting Cloud Native Development as your preferred form of application development are as follows:
Adopting Cloud Native Development improves your performance as you get access to the native features of public cloud services. For example, with Cloud Native Development, you can deal with an I/O system that works with load-balancing and autoscaling features.
Cloud-native applications use their underlying resources more efficiently by using their cloud-native features and APIs. It means providing better performance at a lower cost.
Efficient applications typically cost less. The user gets a monthly bill from the cloud provider based on the number of resources the user has consumed, so efficient use of resources saves the user a lot of money.
The user gets direct access to the load-balancing and autoscaling features of the cloud platform, as he writes the application to the native cloud interface.
Some disadvantages of adopting Cloud Native Development as your preferred form of application development are as follows:
Cloud Native Development is complex. Moving and reworking an existing application to the cloud is not an easy job. Along with being completely rearchitected for the cloud, organizations would also require the underlying infrastructure to support this migration.
Once an application is localized to a cloud platform, it becomes very difficult to port it to another cloud platform, as it would require a huge amount of rewriting the software and refactoring the code. Therefore, you are practically locking yourself into one cloud platform.
In today’s dynamic business environment, business systems can no longer just merely enable business capabilities. They need to evolve into tools for strategic transformation, that accelerate business growth and business velocity for the future. They would require new ideas instantly and regularly to ensure their survival in the market. The Cloud Native Development model suits that requirement perfectly.
