Microservices Using .Net Core

Today, we delve into Microservices. We see large projects working on monolithic architecture and service-oriented architecture (SOA). As we have cloud providers providing affordable cloud services, monolithic applications are migrated into Microservices.

Why no to Monolithic?

Monolithic applications are multilayered, working on a system, or scaled into distributed servers. The components are loosely coupled but are dependent, failure in a component could stop the entire application. Another disadvantage of Monolithic architecture is that, it demands the developers to know the system in and out. A change in one component or unit could lead to a change in other components and this change adds to the testing phase.

Why Microservices?

Microservices are the variants of monolithic architecture, each component is a Microservice that is an independent logical construct. These are autonomously independent services, that encapsulate business scenarios, or can be centered around the business scenarios. These are easily deployable and scalable and can also perform as an individual service. A migrated monolithic application consists of multiple Microservices distributed within the set of clusters. As each Microservice is an independent unit, it can be scaled, deployed, updated, or distributed without disturbing your application. These characteristics of Microservices make them appealing.

Why Microservices are Popular?

  1. Build and Operate a Service at Scale: As Microservices are managed independently, the resources they need can be scaled out.
  2. Fault Isolation: Microservices are independent and encapsulate their business capabilities. A failure of one Microservice will not affect the performance of others even if they are running under the same cluster. For example, in an eCommerce site, a failure of a Microservice displaying the current shopping cart will not affect another service which is responsible to display the previously purchased items in the shopping cart.
  3. Ease in Updating: Teams can program the Microservices parallelly. This boosts development. Any change request from clients can be addressed immediately. Adding extra features or maintaining the Microservices gets easier.
  4. Facilitates Development: Newbies can quickly work on their Microservices without knowing the entire applications. A small focused team can deploy the services as required and this won’t affect the performance of the application.
  5. Clear Code Boundaries: For Large enterprises with different departments working on a product, Microservices can easily match up with the organization’s departmental hierarchies.
  6. Technology Adaptation: Microservices are language and platform independents. You can choose the best language for the job, For instance, you can have .NET for your core computing logic and Node.js or JavaScript for front-end logic services. Porting a Microservice or entire cluster is easier.
  7. Adapts Quickly: New features and requests need quick attention. Adapting to compliance and rules gets easier.
  8. Reduces Dependencies on Infrastructure: By adapting to cloud development, it reduces the infrastructure dependencies.

When Microservice Architecture is the right choice?

Some applications that are simple and have fewer components may not need Microservices, especially when they are interacting with each other and do not need outside references. Microservice architecture is used for complex applications with multiple components that are developed by different teams. It simultaneously facilitates the development process for the entire application.

Takeaway: Usually Microservices contain their own datastore and provide well-defined interfaces and protocols. They remain consistent and available even in the presence of a failure. Even if the machine hosting a Microservice goes down, the functionality provided by the service will still be offered by the application. Microservices are great and there is a lot of work involved in building the Microservices scalable application on the .NET core platform. For a more extended stability, Microservice architecture is worth having.

At BundleN, we experiment with stack combinations on our own time.

For potential clients interested in this stack, we can always give a demo of what we have up until that point of time. You can reach us at sales@BundleN.com
