The cloud revolution has been into our lives for almost a decade now. It can be said that Cloud Native is a path to innovation established in order to take complete advantage of Cloud Computing. Cloud Native is recently one of the biggest trends in the software development industry.
A survey of 100 IT decision makers conducted by NetEnrich stated that 85% of them claim moderate or extensive use of Cloud infrastructure.
This proves how important the cloud is, for an IT infrastructure.
Benefits of Cloud Native vary as per the requirement of enterprises in various ways. Some enterprises use this for reduction of costs and improvement in margins. While for some businesses, this might be helpful in offering speedy deliverables, or any other goal.
But, What Basically Is Cloud Native?
It is just an approach to build and run applications.
Confused how just an approach can help you achieve many aims? Well, if you are looking for an answer to all these questions, you have landed at the right place. This blog will solve all your confusion regarding Cloud Native.
Since long, enterprises have been focusing on digital transformation. But to lead the tech-savvy companies to digital transformation, cloud-ready applications were no more enough.
The cloud-ready applications were once-only developed programs that were ready to launch on the cloud. But there were various issues faced with the cloud-ready applications. Cloud systems have become a standard infrastructure for SMEs as well as large-scale enterprises.
The features of the applications were suitable only for a static environment. Therefore, in order to deploy the application in the cloud, some modifications are required.
The cloud-ready applications were developed in such a way that there were dependency created on the Operating Systems as well as the hardware.
The cloud-ready applications were developed custom to any specific environment. Therefore, it requires custom configuration which made the maintenance difficult.
The cloud-ready applications were built with a special configuration and were limited to server capacity. Expansion of scale also required the expansion of infrastructure.
Due to these types of challenges faced by traditional cloud-based applications, cloud-native applications came into the picture.
Cloud Native application means building and operating applications on the cloud with the use of containers, microservices, orchestration, and infrastructure that is expressed as a code. The major objectives of Cloud Native applications are to enable faster software development, along with scalability and improved margins.
“Cloud Native” is totally about how the applications are created and deployed, not where the applications are developed.
The Cloud Native applications are developed as microservices running in the containers to maximize resilience, manageability, and scalability.
According to Mike Kavis, Managing Director with Deloitte,
“A cloud-native app is specifically architected to run in the elastic and distributed nature that is required by the modern cloud computing platforms”.
In other words, if we talk about the Cloud Native definition by the Cloud Native Computing Foundation (CNCF), an organization aiming to develop and drive the adoption of Cloud Native programming, the definition goes like:
“Cloud Native computing uses an open source software stack to be:
Cloud is about how you do computing, not where you do computing – Paul Maritz
Cloud Native app development comes with five fundamentals Cloud, DevOps, Containers, Orchestration, and Microservices oriented architecture. Cloud Native app also includes Agile Methodology and various modern methods of deployment in an application. In order to get an in-depth understanding of the working of Cloud Native, let us study the different stages of the Cloud Native application.
A Container is an exclusive package for your software which consists of everything you might require to build an application altogether.
For instance, the application server, a Java VM or the application itself can be put together in the container. Once the container runs on the virtualized environment, it will segregate the application and make it independent of the environment. Also, these containers are highly portable, .i.e. it can run simultaneously on the development system, test system, and the production system.
Ultimately, the container is something you can be dependent on, for your application to run. All you need to do is switch the container on as it contains everything your application might require. It solves the deployment problems faced earlier.
To run an application fully on the Cloud platform, the container is just the first step. There are many challenges you may experience after the containers start running. Furthermore, you might require to manage various things manually.
Tasks such as monitoring the system, switch the container on and off as and when required, adjusting all the configuration parameters are done manually. But, in order to do all these tasks manually on time, we need to be as quick as the Flash (which ain’t possible for everyone). This is where we require the tools that can automate these tasks. These tools are called orchestration tools and the process is known as Orchestration. Some of the well-known orchestration tools are Kubernetes, Apache Mesos, Docker Swarm, Nomad, Amazon’s ECS, Kontena.
The approach utilized for developing the Cloud Native application by gathering various small independent services that run its own processes and implements their business capabilities is called microservice. All these work together and manage the overall functionality of the whole system. The development of Cloud Native applications is done as a system of Microservices. With this approach, scaling can be made highly efficient as each of them has one functionality, well-defined boundary, and API.
There are certain rules and guidelines to be followed to build a Cloud Native application. These rules are described in a manifesto named Twelve-factor app developed by Heroku, a leading Cloud computing company.
DevOps is basically the practice wherein development and operations are combined in order to reduce the life cycle of system development. It aims at delivering the application enriched with quality features to meet the customer requirements. DevOps lets the organizations deliver applications at a fast pace. It creates an environment where testing, development, and launching of the software quick, efficient and consistent.
With the advancements in the technology field, the enterprises have begun focusing on differentiating their business to stay ahead of the competition. These applications are specifically built for the Cloud model. The major purpose of implementing Cloud Native application is to benefit fully from the Cloud computing system.
Below mentioned are the certain benefits of using Cloud Native applications.
Cloud Native application tends to offer a competitive advantage as it lets businesses build and deliver applications quickly in response to customer requirements.
Cloud Native applications aren’t just meant to work on public clouds, but applications built can run on both public as well as private clouds without any modification.
Cloud Native applications come with the auto-scale feature in order to let you handle continuous business requirements. With this, the enterprises deal with the pay-as-you-go model letting them pay for computing services utilized by them based on the time frame they used. Along with that, the downtime with Cloud Native applications is very less or not at all.
With Cloud Native applications being resilient to failures, they handle the outages and enable corrective actions. The application starts processing instant moves from one data center to another without any interruption to the service in case of any failure.
Quick deliverables are the aim of every company in the software industry. SME or large scale enterprise, all of them achieve this aim with the use of Cloud Native. With Cloud Native, the time utilized for the development of the application can be moved from months to days or hours. Ultimately, Cloud Native is the reason for organizations to be more responsive to the client’s requirements.
With Cloud Native, highly efficient applications usually cost less. This application lets you pay for additional resources only when it is required. You do not need to pay for the resources even when you don’t have a large number of visitors.
Tech Giants have already adopted. Haven’t You Yet?
Cloud-Native is redefining the way in which enterprises scale their businesses. Below mentioned are the ones that adopted Cloud Native:
Cloud is a game changer in the competitive world of technologies. Cloud Computing is entirely shaping our ways to live and work. Cloud Native is perfect for entrepreneurs who are looking to enhance their existing product by reducing the operating costs and improving margins. Cloud Native is also a perfect option for someone who wants to build an application entirely on Cloud. The organizations that plan for reinventing themselves through digital transformation require Cloud-Native application in one or the other way.
Today, over 50% of US enterprises have started utilizing the Cloud to some extent. This trend is set to accelerate, with Infrastructure as a Service (IaaS) growth at 40%.
Known a lot about the cloud-native applications, but let us now check how the cloud-based applications and cloud-native applications are different from each other.
Cloud Native Applications
|The cloud-based applications are designed to be locally hosted. The development and deployment of the applications take a longer period of time.||When talking about cloud-native application, these are developed on the basis of a framework that is specially developed to enhance resilience. This makes the process of development quicker than the|
|The Cloud-based applications are built in such a way that it develops certain dependencies within the application and the OS, hardware, storage, backing services. Due to the dependency, the processes of migrating are made difficult and risky.||While in the case of a cloud-native application, the architecture allows the developers to use a platform which does not have infrastructure dependencies. The team just need to focus on software and nor on configuring, patching, maintaining the operating systems.|
|The Cloud-based applications come with a customized and dedicated infrastructure solution for each application. This can be a reason for the delayed deployment of the application at times. The solution offered here is mostly over-sized and is based on the worst-case capacity.||The Cloud Native application platform operates by automating the infrastructure provisioning and configuration. Due to this, it dynamically allocates the resources based on the requirement of the application. This makes the system appropriately sized and optimizes the lifecycle management, resource allocation, improving scalability. This approach also lets you recover from the failures in order to reduce the downtime.|
|At the time of developing a Cloud-based application, the developers release the software periodically. The entire application is released once the code has been built, even when a lot of its’ parts were ready earlier. The only dependency is the release vehicle. In such cases, certain features get delayed and the business experience a great loss.||The continuous delivery model is what Cloud Native application is highly well-known for. While developing a Cloud Native application, the individual software updates are available for release as they get ready. This rapid delivery of the software makes the organizations respond effectively to the needs of the customer. This practice is best when there is test-driven development and continuous integration.|
|The cloud-based applications are built on monolithic architectures which combines various services in a single package of deployment. This develops dependencies between services and makes the developers lose the agility while development process.||Cloud Native applications are built on the basis of Microservices architecture wherein, applications are decomposed into small, independent services. And these services tend to make all the necessary changes as soon as the need arises making entire application independent.|
Cloud Native is a highly innovative approach in the field of technology. All the aspects of Cloud lead the technology field to a single context .i.e. Innovation. Cloud Native is all about de-risking the technical risks. Earlier, we used to go slowly in order to reduce the risk, whereas, with the cloud-native approach, it is about taking minor but low-risk and reversible steps to avoid the dangers.
