Hello, week-9. I want to post a blog to quickly review the API topic to learn more about REST calls. I got confused; I researched about it. It has the Understanding And Using REST APIs.

 

What is a REST API

 

API (Application Programming Interface) – A set of rules allows programs to support any other. The developer creates the API on the server and enables the client to speak to it. 

The REST (Representational State Transfer) determines how the API. It is a set of rules that developers follow when they create their API. One of the rules states that one should get data (called a resource) when linking to a specific URL. Each URL made a request, while the data sent back to is called a response.

The Anatomy Of A Request #

It’s important to know that a request with four points:

  • The endpoint
  • The method
  • The headers
  • The data (or body)

 

The endpoint – URL that requests for (root-endpoint/?). The root-endpoint is the starting point of the API that is ordering.

The path determines the resource request. For example, it is like an automatic answering machine. That asks to press 1 for service, press 2 for another service, 3 for yet another service, and so on.

The Method

The method is the type of request sent to the server:

  • GET – Request to get a resource from a server. It will perform a `GET` request; the server looks for the requested data and sends it back.
  • POST – Request to create a new resource on a server. It performs a `POST` request, the server creates a new entry in the database and tells whether the creation is successful.
  • PUT & PATCH – Requests to update a resource on a server. If performing a `PUT` or `PATCH` request, the server updates an entry in the database and tells whether the update is successful.
  • DELETE – Request to delete a resource from a server. If performing a `DELETE` request, the server deletes an entry in the database and tells whether the deletion is successful.

These methods provide meaning for the request made. Perform steps: Create, Read, Update and Delete (CRUD).

The HEAD: it used to provide information to both the client and server. It has many purposes, such as authentication and giving information about the body content. It can find a list of valid headers on MDN’s HTTP Headers Reference.

The Data – contains information sent to the server. It only used POST, PUT, PATCH, or DELETE requests.

Hello, I want to write this
blog after looking over some class activities again and seeing any questions to
review, but something caught my attention. I read the word
“microservices” in some class-work exercises; I got interested and
looked it up again. I found two links that helped me understand What are
microservices? And examples from Amazon company.

 

What are microservices? 

Microservices (microservice architecture) – is an
architectural method that structures an application as a collection of services
that are

  • Highly maintainable and testable
  • Loosely linked 
  • Individually deployable
  • Organized around business capabilities
  • Owned by a small team

The microservice architecture makes applications easier
to scale and faster to develop, enabling innovation and accelerating
time-to-market for new features to reduce complex applications. It even allows
an organization to evolve its technology stack.

The pattern language guide 

The microservice architecture isn’t perfect; It has
several problems. Moreover, when using this architecture, many issues must
address.

The microservice architecture pattern language is a set
of patterns for applying the microservice architecture. It has two goals:

  • The pattern language allows whether microservices are a good place for application.
  • The pattern language allows the microservice
    architecture favorably.

Characteristics of Microservices

  • Autonomous – Each element set in a
    microservices architecture can be developed, deployed, operated, and scaled
    without affecting the functioning of other benefits. Services don’t need to
    share any code or implementation with other services. Any connection between
    individual components happens through APIs. 
  • Specialized – Each service is designed
    for a collection of capabilities and focuses on solving a specific problem. 

Benefits of Microservices

  • Agility – promote an organization of small and
    independent teams that take ownership of their services. Groups work in a small
    and well-understood context and are allowed to work independently and fast. It
    helps to shorten construction cycle times. It benefits significantly from the
    throughput of the organization.
  • Flexible Scaling – Each service is to be
    independently scaled to meet the demand for its support application. It enables
    teams to support requirements, precisely measure the cost of a feature, and
    manage availability if a service experiences a spike in demand.
  • Easy Deployment – Enable continuous combination
    and delivery, helps try out new ideas, and rolls back if something doesn’t work.
    The low cost of failure enables experimentation to update code and stimulates
    time-to-market for new features.
  • Technological Freedom – It doesn’t follow a
    “one size fits all” plan. Teams have chosen the best tool to solve
    specific problems.
  • Reusable Code – Dividing software into small
    modules, which enables teams to use functions for multiple purposes.
  • Resilience – Service independence increases an
    application’s stand to failure. With microservices, applications handle
    complete service failure by discrediting functionality and not crashing the
    entire application.
