Are your applications still platforms dependent and monolithic? If yes, it is time to experience and get started with microservices.

Microservices architecture was introduced to overcome the difficulties of monolithic architectures. Microservices architecture helps the user to deploy the same application on different platforms.

Monolithic applications are simple to develop but have various limitations. When the applications expand, it becomes big and requires more lines of code. It is difficult for a developer to implement new features and remove bugs due to the big size of the application.

In the latest technology, applications design is in such a way that the developer can move the changes to productions many times.

The fundamental idea of microservices is to break down an application to make it easier to build, maintain and scale.

Few advantages of working with microservices:

  • Microservices focus on a specific requirement.
  • Small teams are sufficient to develop microservice applications.
  • Small teams are sufficient to develop microservice applications.
  • Microservices applications are flexible and offer high performance.

For example, consider an online application which has separate microservices for its various processes. An online application holds many active parts that the developer sets and configures.
Through this article, let us discuss the steps to implement microservices with spring boot.

Step 1 – Create WebMicroservice

  • Download the WebMicroservice.
  • Open Spring Tool Suite (STS), click on the File menu and then click on Import as shown below.

  • From the import screen, click on General from the drop-down. Select Existing Projects into Workspace and then click Next button to continue.

  • Click on Select archive file. Select the archive file and add this to STS.
  • Open the file application.properties. Enter Server port for WebMicroservice. Enter the URL for RegistrationMicroservice and S3UploadMicroservice.

  • The following templates are listed.

  • Open the file DynampdbController.java and check on the method registerUser(). Using this method, we send the object RegisterModel() to the RegisterMicroservice by using the RestTemplate'spostForObject Http Method.

Step 2 – Create RegistrationMicroservice

  • Download the RegistrationMicroservice.
  • Using the above steps listed in Step 1, import RegistrationMicroservice into STS.
  • Open the file application.properties. Enter the details like the secret key access key etc.

  • Open the class DynamodbController.java. The data will be available from WebMicroservice under the registeruser() method. The data is passed to the DynamoDBModel class using @ReqestBody.

Step 3 – Create S3Microservice project

  • Import S3UploadMicroservice project into the STS.
  • Open the file properties and enter secret key, access key and other details.

  • Open the file S3UploadController.java. In the method imageUpload(), the data from WebMicroservice is seen.

  • Right-click on the WebMicroservice project and execute as Sprint Boot app. Execute the S3UploadMicroservice and RegistrationMicroservice.
