Cloud Native Architecture - Advantages and Disadvantages

When we speak of cloud native applications, one should understand that it refers more to how the application is built and deployed than where the application resides. Amazon was one of the earliest organizations that broke up their monolithic websites and split the functions into smaller services.

Typical Characteristics of Cloud Native Applications

Building cloud-native applications is among the hottest trends in software development and architecture styles today. Cloud-native architecture refers to an approach in which applications are built and run in order to fully take advantage of the cloud computing model.

Typically, cloud-native computing refers to using an open-source software stack (of applications and processes) that is containerized, facilitating transparency, reproducibility, and resource isolation. These containers can be orchestrated to dynamically manage the resources in an optimal way. The applications are generally segmented into microservices, significantly increasing their maintainability and overall agility. In a survey by IBM of IT executives and developers, 87% of respondents who are microservices users agreed that microservice adoption is worth the expenses they bring along and the effort required to operate them.

The cloud computing model packages microservices in containers and incorporates CI/CD software, as well as automated lifecycle management. Loosely coupled microservices form a key part of the cloud computing environment. Communication service providers are now increasingly using the cloud-native model to load applications as stateless microservices packaged in containers or VMs along with APIs.

So what about Cloud-Native Applications

If you plan to leverage cloud-native features in your IT systems, you can enjoy many advantages. However, they also come with an attached cost. This depends a lot on the applications and the data generated. Sometimes, going cloud-native may not be economically viable for you. Let us briefly examine the pros and cons of going cloud-native.

Going Cloud Native – Pros

The pros of going with cloud-native features include the following:

As far as performance is concerned, being able to access native features of public cloud services will help to provide better performance than non-native ones. It is easier to handle an I/O system with autoscaling and load-balancing features when using a cloud-native application. This makes for easy scalability.
Cloud-native applications use features and APIs so as to make efficient use of the underlying resources. This shows up as better performance at lower costs.
Cloud-native applications cost less to run and are more efficient. Service providers work on a monthly charge according to the resources that you use. So you pay only as much as you use, and this leads to savings as overheads are lower.

If you run an on-premise software application and it experiences peak hours, your infrastructure has to be one that supports the peaks. A lot of the infrastructure will lie idle during non-peak hours, increasing costs. With cloud computing, you can scale when the peaks occur and scale back later, leading to lower costs.

Going Cloud Native – Cons

Cloud-Native is complex. Reworking and moving an existing application to the cloud is not an easy job. They have to be re-architected for the cloud, and organizations also require the underlying infrastructure that is required to support this migration.

Another cost is giving up portability. Applications that have been localized for one cloud platform cannot be easily ported to another cloud platform. This involves a large amount of rewriting the software and refactoring the code. Therefore, for all practical purposes, you are locked into one cloud platform.

When applications are scheduled to run on a specific cloud platform for many years, you can get your investment back. The advantages of going cloud-native are specific and can be judged on a case-by-case or application-by-application basis. There are no readymade checklists that you can use, but instead, decide what is best for you according to the trade-offs you are ready to adjust to.

Microservices come with their own operational complexity. When you go cloud-native, you are effectively trading off individual developer productivity in exchange for a complex system.
 
End Thoughts
 
Business systems for the future need to evolve from merely enabling business capabilities to tools of strategic transformation, accelerating business velocity and growth. For businesses to survive, it is imperative to get new ideas to the market at the earliest possible. The cloud-native model suits that requirement perfectly.
