Cloud Native Applications


Cloud Native Applications are built and run to utilize the cloud computing delivery model. Cloud Native Applications exist in the cloud. These applications are made up of Microservices housed in containers. The purpose of containers is to allow transfer of application between clouds. A native application utilizes services and infrastructure from cloud computing. The general cloud computing providers are Amazon EC2, and Microsoft Azure etc. etc. 

Building Blocks of a Cloud Native Application 

Cloud Native Applications are deployed as microservices abstracted to underlying infrastructure and delivered through a DevOps pipeline.

DevOps is the partnership between software developers and IT operations. Its objective is to constantly deliver quality driven application that help resolves customer challenges. Agile allows for continuous development of an application or software and is about shipping small batches of ab application to production constantly. 

Microservices architecture is a way of developing applications as sets of independent services (microservices). Each microservices performs a specific function and are all these microservices are independent of each other. The microservices use lightweight HTTP, REST or Thrift APIs for communicating between themselves. Each microservice can be implemented, upgraded, scaled, and restarted independent of other services in the application.

Containers are a form of operating system virtualization. Containers are an executable unit of software in which application code is packaged, along with its libraries and dependencies, in common ways so that it can be run anywhere, whether it be on desktop, traditional IT, or the cloud. Containers are small, fast, and portable because unlike a virtual machine, containers do not need include a guest OS in every instance and can, instead, simply leverage the features and resources of the host OS.

Advantages of Cloud Native Applications 

Cloud Native Applications provide agility and portability across cloud environments. 

Time to Market is becoming significantly important for businesses. Competitive businesses want to reach out to their customers with new applications faster and they want to stay ahead of their competition in applications delivery to their audiences. With DevOps automation across the software delivery process becomes possible. Cloud Native Applications support DevOps process. 

It is important for organizations to meet the ever-changing demands of their customers. First class customer experience demands to experience new features to be readily available and constantly changing as per the need. Cloud Native Applications allow you to frequently provide your audiences and customers with new updates and features. API integration has made it easier for mobile ready interfaces. 

With Cloud Native Applications the infrastructure needs and efforts get minimized. With Server-less computing platforms, you can upload code in the form of functions and the platform runs those functions for you, so you don’t have to worry about provisioning cloud instances, configuring networking, or allocating sufficient storage. 

With Traditional legacy applications downtime was a normal thing to occur and fault tolerance was expensive. Whereas with modern cloud-native approaches like microservices architecture and Kubernetes in the cloud, you can more easily build applications to be fault tolerant with resiliency and self-healing built in. Cloud-native microservices helps you achieve higher uptime and thus further improve the user experience.

With legacy applications businesses faced numerous challenges. There was licensing involved and hardware elements to be taken into account. All this was vendor lock in phenomenon and businesses used to get into 3 to 5 years contracts. This was an expensive exercise. Thanks to Cloud Native Architecture, large companies now have the choice to use a combination of on premise and cloud platforms.
