Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
How do you identify a Microservice?
Inability to scale individual components to meet changes in demand.
Lack of automated unit and functional test cases.
Tight coupling between components makes it difficult to deploy frequently.
High maintenance cost.
Less adaptable to future changes.

Where are Microservices used?
When using microservices, you isolate software functionality into multiple independent modules that are individually responsible for performing precisely defined, standalone tasks. These modules communicate with each other through simple, universally accessible application programming interfaces (APIs).
Should that be a Microservice?
If a module needs to have a completely independent lifecycle (meaning the code commit to production flow), then it should be a microservice. It should have its own code repository, CI/CD pipeline, and so on. Smaller scope makes it far easier to test a microservice.
How big should be a Microservice?
Microservices: It's not the size that matters, but the scope. A common question people ask is How big (or small) should my microservice be? One common answer is that the size of a microservice can be variable, but it should be coded by no more than a dozen people (the so-called two pizza rule).
Are Microservices worth it?
Microservices are good when your monolith becomes too difficult for multiple teams to manage and update safely. Yes, they are complex but so are the monoliths to whom this pattern is advertised. Also, containers can be used for building monoliths. They just happen to be an easy medium for microservice design, too.
What is meant by Microservices?
Microservices are a software development technique a variant of the service-oriented architecture (SOA) structural style that arranges an application as a collection of loosely coupled services. In a microservices' architecture, services are fine-grained and the protocols are lightweight.
Is an API a Microservice?
An API is a contract that provides guidance for a consumer to use the underlying service. A microservice is an architectural design that separates portions of a (usually monolithic) application into small, self-containing services.
What is the difference between rest and Microservices?
MicroServices can be implemented using REST style, an architecture which defines that overall solution (application, product) should be split into multiple services, that interact with each other. Microservices is more about architecture whereas a RESTful API focuses more on how to expose those microservices.
What is difference between Microservices and Web services?
Microservices are small, autonomous services that work together, while web services are any service that is available over the internet and is built using standard internet technologies. Microservices are a set of small self-sustained small services or applications designed to solve problems for systems that are big.
Do Microservices have to be RESTful?
Isolation or fault-tolerant is one of the most important goals when designing a microservice. Therefore, Microservices is more about architectural and design style, and you may be able to implement a microservice without RESTful API. However, RESTful API makes it easy to build a loosely coupled Microservices.
How do you test Microservices locally?
Ensure I was on the correct code branch (either master or feature_xyz)
Pull down the latest code for that branch.
Ensure all dependencies were up to date.
Run any new database migrations.
Start the service.
Is testing Microservices application complex?
But in many ways, testing a microservices' application is no different than testing an application built using any other architecture. Microservices use well-known technologies, such as REST or queues, for which the software industry already has well-established testing tools and best practices.
What defines a Microservice?
Microservices — also known as the microservice architecture — is an architectural style that structures an application as a collection of services that are. Highly maintainable and testable. Loosely coupled. Independently deployable. Organized around business capabilities.
How do you write a simple Microservice?
Step 1: Create a Maven project using Spring Initializr https://start.spring.io/
Step 2: Choose the Spring Boot version 2.2.
Step 3: Provide the Group name.
Step 4: Provide the Artifact id.
Step 5: Add the following dependencies: Spring Web, Spring Boot DevTools, Spring Boot Actuator, Config Client.
