What are Cloud Native Microservices- their setup and benefits?

Dividing application into discrete independent parts makes it greatly easier for the developers to craft agile and much more resilient applications. This approach also significantly lessens the development cycle, which translates into rapid innovations, faster executions, and an incredible user experience.

These small but independent parts of cloud native applications are the cloud native microservices. The core of cloud native application architecture, the cloud native microservices is now the key tools used by the organizations making a move to the cloud.

With this article team Technovature throws light on the various aspects of cloud native microservices, and sums up their benefits while also elaborating their setup.

So let’s delve into the details!

What are cloud native micro services?

Cloud native microservices point the application design methodology in which the app is divided into the discreet, independent, workable units. Those units are called microservices.

The cloud native microservices arrange the application into the multiple independent services, with each one serving its own function. And, sharing a common data and network interaction, they enable the app to function properly- in unison!

Microservices and cloud architecture go hand-in-hand, because the cloud native applications are based on the microservice architecture. And, to the surprise cloud native microservice architecture have been around longer than cloud native computing.

Other advantage of microservices is that they don’t need to run them only in cloud environment. Using Kubernetes the microservices can also be deployed on premises.

How to setup/build cloud native microservices?

Cloud native microservices can be implemented as an architectural style for the applications in myriads of manners. When one is ready to adopt microservice architecture then for the development or deployment the 3C’s are must to be followed-

a) Componentize b) Collaborate c) Connect

But with the benefits in mind, developers tend to code the microservice without a proper design plan. In cloud native microservices it is always crucial to plan first then code. The following 5 important steps regarding how to build microservices will help you setup & build efficient microservices.

1. Getting the right blueprint

Directly starting the microservice development with code might land you into troubles. Creating a single service is an easier task but that’s not the requirement. The final function of all the microservices is to deliver a functional application in the aggregation.

The first step should be in regards with the defining the application functionality then identify the individual microservice requirements.

2. Anti-pattern

The system designs mostly interpret the structure of the organization designing them. But the same must not be followed in case of microservices. In place of mirroring the organizational structure investigate the microservice designs in the light of functionality to be delivered in the new architecture.

3. Operational Support

Apart from the functionality, as mentioned in the first two points, operational support for the new architecture needs to be ensured accordingly. Tracking transient resources and maintaining a history of application metrics, one can easily perform time-series assessments.

4. Performance & Resilience

Each microservice is required to deliver high performance and continued operations even in the instances of resource failures. Therefore it is crucial to address the risk potentialities as early as possible. Preparing the microservices for load variations and lack of resources will ensure the application’s robust performance against the real-world-challenges!

5. Future Planning

The applications tend to develop and evolve fast, and new features are rolled out in the latest versions. With the continuous deployment ventures the microservice applications are continually developing.

So the microservice must be designed in a way to conform to the desiderata and empower the updates fast & easy.

What are the Benefits of using Microservices in a Cloud-Native architecture?

Developing the complete application as a single monolithic structure creates several troubles for the connectedness and the dependency of all units with each other. Shifting away from this pattern and implemented cloud native microservices in cloud native application designs render several benefits.

Let’s talk about them individually-

1. Enhanced Productivity

Breaking down an application into miniscule fragments is much easier to develop & maintain. Each of the service can be independently managed in any of the programming language across different software environment, as per the needs.

2. Greater Resilience

The microservice-based architecture eases up the process of investigating and resolving the issues. Individual modules facilitate specific fault isolation and the larger application remain impervious to that single failure.

3. More scalability

The polyglot nature of the cloud native infrastructure allows any programming language to execute the microservice without any issue of incompatibility. With microservice architecture any service can be scaled individually and the new components can be added without downtime or redeployment.

4. Optimized Functionality

When the focus is on individual service in lieu of the entire application then the components can be customized as per the need and improved functionality. Workability of each module separately helps teams focus on capabilities rather than technologies.

5. CI/CD

DevOps philosophy and Agile development approach both are centred around CI/CD. The cloud native microservices empower the cross-functional teams to craft, check, deploy, and update the services independently. This leads to the faster deployments and troubleshooting.

Frequently Asked Questions

1. Are micro services for cloud-native apps?

Mainly they are used for cloud native apps, but with Kubernetes they can also be used in on-premise applications.

2. What are the benefits of using microservices in a cloud-native architecture?

Better productivity, enhanced resilience, better scalability, optimized functionality, continuous improvement and continuous development are the major benefits rendered by the microservices.

3. Can we develop cloud native microservices using Apache camel?

With Instana- the automated APM, cloud native microservices can be developed with Apache Camel.

4. Why is microservices architecture better compared to others?

Microservices allow division of application into small autonomous discrete components that can be operated individually, without disturbing the application as a whole. This empowers the developers with several competitive edges.

5. How to develop cloud native applications with microservices architecture?

The cloud native microservices arrange the application into the multiple independent services, with each one serving its own function. And, sharing a common data and network interaction, they enable the app to function properly- in unison!
