Applications such as Expedia, Amazon, Netflix or Facebook are using an API that facilitates the sharing data from one application to another. There are hundreds of APIs for many fields like finance, social network, payments and e-commerce. Nowadays, the fastest-growing category APIs is sharing and analyzing of data across various applications which is a place the characteristics of the API determine the value of the application or deem it untenable for use in the real world. But how could APIs connect each application together, let’s us take a deep dive into the world of APIs.

API stand for Application Programming Interface which includes three important components

• Procedures: Known as routine which refer to the specific tasks or functions a program performs. For example: Facebook provides a search API for developers to examine data for analytical purpose
• Protocols: The format is used to communicate data between applications. However application might not have the same format
• Tools: Simply put – building blocks which is the recipe to construct new program

APIs are needed to bring applications together to perform a designed function which allows to use, share and execute data. APIs act as middle man, this allows developers to build new functions between applications and businesses use on a daily basis.

How APIs actually work?

Application: Enterprise businesses and corporation rely onto user financial data, inventory levels and purchase order confirmation back and forth between suppliers, customers and partners. Consumers and business depend on mobile application, spending much time per day on smartphone and tablet apps to exchange businesses with partner and customers.

Programming: Application relies on programming. The application does not make itself. In other words, we would not be able to make new application without developers who write the code to create, testing and design the application software and user interface.

Interface: This is where users and application interact with each other

API is important that without it we would not be able to order stuff from Amazon or personalize your favorite Google homepage. The simple way to understand APIs is to understand that API is an interface that let this application talk to another inside the application via commands designed by programmers.

Types of APIs

• Rest APIs: known as RESTful APIs, stands for Representational State Transfer. It has grown in popularity of late, as an essential part of Web Services. It’s designed for developers to perform requests and receive responses via HTTP. There are four types of HTTP commands that REST is based on which are GET, PUT, POST, and DELETE. Instagram uses API for users to pull up information and pictures
• SOAP APIs: Stands for Simple Object Access Protocol. SOAP is a protocol that is defined by a standard. It is dependent on XML-based systems and programming, has larger and more expensive data. Despite the disadvantages, SOAP provides better security for users.
• RPC APIs: Remote Procedure Call was the earliest form of APIs. They are designed to execute the block of code on different servers.

APIs are running data for business every day. They give businesses and users the flexibility to increase productivity and improve security. Taking advantage of APIs can help them have innovative approaches. While the potential is undeniable, efficiency is still another matter.

Hello, I want to write this blog after finishing my exam like an hour ago; I am looking over some class activities and see any questions to review, but something that sometimes confused me. I read the word “docker-compose” in some class-work exercises; I got interested and looked it up again. I found two links that helped me understand what Docker Compose does and how you use Docker Compose?.

Docker Compose: Run multiple containers as a single service or extend many different Docker containers midway. Even an essential tool for any application that needs various micro-services, as it allows each service to be in a separately managed container easily.

What Does Docker Compose Do?

Docker containers are running applications in an isolated environment. Its application deployments are arranged in Docker for the benefit. However, it’s often complex as running a single container. Usually, Many containers come together to act as one service made up of many changing parts.

Running all deployment time is disordered, so Docker provides Docker Compose; it runs multiple containers to clean it up. It helps all arrangements in one YAML file and starts all the containers with one 

command.

Rather than having all services in one big container, Docker Compose allows to split them up into individually manageable containers. This is better for building and deployment, and it can manage all of them in separate codebases and doesn’t need to start each container manually.

Using Docker Compose is a three-step process:

• Build the part images using their Dockerfiles, or pull them from a registry.
• Set all of the component services in a docker-compose.yml file.
• Run all of them together using the docker-compose CLI.

Docker Compose still builds and publishes Docker containers using a Dockerfile. But, instead of running them directly, it can use Docker Compose to manage the configuration of a multi-container deployment.

How Do You Use Docker Compose?

The form for a docker-compose file is done in docker-compose.yml. It doesn’t need to place this at the root of a project like a Dockerfile. It can go anywhere as it doesn’t depend on any other code. However, it builds the images locally and will need to go into a project folder with the produced code.

A Compose configuration file that runs a WordPress instance using the WordPress container off the Docker Hub. However, this depends on a MySQL database, which Composes also creates.

• First, a version number since the arrangement can change depending on which version.
• Next, A list of Services. 
• Lastly, the volumes are stored.
