Which is best MVC or 3-tier architecture?
A 3-tier architecture is linear where the client tier never actually communicates with the data tier–all communication passes through the middle tier. MVC on the other hand is more triangular where the view sends updates to the controller and receives updates from the model and the controller updates the model.
What is a VPC in AWS?
Amazon Virtual Private Cloud (Amazon VPC) enables you to launch AWS resources into a virtual network that you’ve defined. This virtual network closely resembles a traditional network that you’d operate in your own data center, with the benefits of using the scalable infrastructure of AWS.

What is the difference between MVC and Microservices?
How The Two Differ? MVC: Division across three code components only Model, View, and Controller. This model is being used by companies like Microsoft, Dell, and Marketwatch. Microservices: An app is divided into a set of specialized which are not predefined like that in MVC and interact with each other using APIs.
Can one microservice call another microservice?
There are two basic messaging patterns that microservices can use to communicate with other microservices. Synchronous communication. In this pattern, a service calls an API that another service exposes, using a protocol such as HTTP or gRPC.
Is spring boot a microservice?
With Spring Boot, your microservices can start small and iterate fast. That’s why it has become the de facto standard for Java™ microservices. Quickstart your project with Spring Initializr and then package as a JAR. With Spring Boot’s embedded server model, you’re ready to go in minutes.
What is difference between microservices and RESTful API?
Microservices: The individual services and functions – or building blocks – that form a larger microservices-based application. RESTful APIs: The rules, routines, commands, and protocols – or the glue – that integrates the individual microservices, so they function as a single application.
How many endpoints are in a microservice?
In some cases, there may be only one endpoint, whereas in some other cases, there could be more than one endpoint in a microservice. For instance, consider a sensor data service, which collects sensor information, and has two logical endpoints–create and read.
Can a microservice have multiple APIs?
It’s important to note that no two microservices are alike, and all utilize APIs differently. Some might assign multiple APIs to one service, or use a single API for accessing multiple services.
Is every API a microservice?
Application Program Interface (API) is a way through which you can make sure two or more applications communicate with each other to process the client request. It is incorrect to say that microservices are like web services but more fine-grained. APIs are not microservices.
