Cloud-native application is all about developing new modern applications using native services of cloud or re-factoring and re-architecting the existing applications.
FREMONT, CA: There is a common trend observed with the truly pioneering technology is that it tends to arrive in waves. The first wave, generally, comes with some new offerings that are cheap and easiest way to accomplish a task. It's the second wave, which brings additional benefits and opportunities for a better output. Being a disruptive technology, Cloud computing is reiterating on the same lines by gliding on the second wave of cloud migration.
In the first wave of cloud computing, businesses shifted their data and applications to the cloud, which was easy, cost-effective, and quicker. The first wave, most commonly known as the lift-and-shift wave, simply moved the less-critical, non-strategic, and not so complex applications to the cloud by hosting the virtual machines from on-premises. Data from the traditional data center was on the cloud after the first wave. It ran on an Infrastructure-as-a-service (IaaS) model on public cloud platforms like Microsoft Azure, Amazon Web Service (AWS), or Google Cloud Platform (GCP).
Though these cloud infrastructure services were less-expensive, there was hardly any change in the technology, application enhancements, or optimization of resources after moving to the cloud. This left businesses asking a question, "Is this all that they needed?" And this led to the onset of the second wave of cloud computing, where companies could take advantage of the added capabilities of the cloud to introduce new ideas and products to market faster than ever before.
The Second Wave of Cloud Computing - Cloud-native Applications
The cloud-native application deals with the complete process of the creation of applications and their deployment. It is all about developing new modern applications using native services of cloud or re-factoring and re-architecting the existing applications. This helps companies to take advantage of the added features that the cloud can offer apart from the infrastructural level, both in the functional and non-functional services. Companies can save developmental costs, sometimes by 50 percent, by using the cloud that scales up and speeds up the time to market products and services.
Moving towards the Second Wave
A solid plan and strategy is required for any application transition or migration. Companies should determine which application needs to be moved from hosted-cloud to native-cloud. What will be the benefit of such migration? Will they be cost-efficient? Will they improve the application lifecycle management and many more. Companies must keep in mind that migrating to cloud-native may not always be cost-effective. Only the applications that are strategic in delivering products and services to the customers are the ones worth investing in. Second-wave migration may not be fruitful for the non-strategic applications.
Role of the DevOps
The development and deployment process of cloud-native applications is way different from the legacy monolithic applications. With the use of the technique like serverless, developers need not worry about the primary infrastructure on which they are deploying applications. These features make the use of cloud as a true utility, i.e., always available to serve the needs. Therefore, polishing the skills of the existing developers, hiring experienced cloud-native developers, and bringing an experienced service provider has become the foremost requirement for implementing the cloud-native approach in an organization.
