Keywords

💡Microservices architecture

Microservices architecture refers to a method of developing software where a large application is broken down into smaller, independent services that communicate with each other. Each service runs a unique process and is loosely coupled to others, which allows for greater flexibility and agility in development. In the video, this architecture is highlighted as a way to build applications more efficiently, allowing teams to work independently and update components without affecting the entire application.

💡Loosely coupled

Loosely coupled services are those that interact with each other but do not depend heavily on the internal workings of other services. This concept is crucial in microservices architecture as it allows each service to be developed, deployed, and scaled independently. The video script mentions that these services have their own stack and run on their own containers, which exemplifies the loosely coupled nature of microservices.

💡Containers

Containers are a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another. They are central to the microservices architecture as they encapsulate each microservice, making it portable and easy to deploy. The script mentions that containers are 'plug-and-play', emphasizing their role in the flexibility of microservices.

💡APIs

APIs, or Application Programming Interfaces, are sets of routines, protocols, and tools for building software applications. They allow different software components to communicate with each other. In the context of microservices, APIs facilitate communication between services. The video illustrates how the search microservice communicates with the content catalog through an API when Ron searches for a soccer game.

💡Service discovery

Service discovery is a process in which microservices locate and register with each other to facilitate communication. It is a critical component of microservices architecture as it helps services to dynamically find and communicate with each other. The script describes how microservices use service discovery to 'find each other' before they can work together.

💡Scaling

Scaling refers to the ability of a system to handle a growing amount of work, often by adding resources or instances. In microservices architecture, individual components can be scaled independently based on demand. The video script explains that components facing high load can be scaled independently, which is more efficient than scaling an entire monolithic application.

💡Monolithic applications

Monolithic applications are large, self-contained units where all the functionality is built into a single code base. This is contrasted with microservices in the video, where the development of monolithic applications is described as time-consuming and less flexible compared to the modular approach of microservices.

💡Cloud development platforms

Cloud development platforms provide an ecosystem for developers to build, deploy, and manage applications in the cloud. They often include tools for integrating existing code and services. The video mentions these platforms as enabling developers to use existing code and break away from building monolithic applications.

💡Recommendations microservice

The recommendations microservice is a specific type of microservice that uses data about user preferences and behaviors to suggest content. In the video, this service is used to personalize the homepage for Ron, the soccer fan, by analyzing his viewing history and preferences to show him relevant content.

💡Analytics algorithm

An analytics algorithm is a set of calculations used to analyze data and extract insights. In the context of the video, the development team uses an analytics algorithm to improve the recommendations microservice. They update the algorithm to compare Ron's viewing history with other users' preferences to create a personalized playlist.

💡Personalized playlist

A personalized playlist is a curated list of content tailored to an individual's preferences. The video uses the example of Ron's experience with Dream Game, where the recommendations microservice generates a personalized playlist of soccer games based on his viewing habits. This showcases how microservices can be used to enhance user experience by providing customized content.

Transcripts

Microservices architecture is an approach in which a single application is composed

of many loosely coupled and independently deployable, smaller components or services.

These services typically have their own stack running on their own containers.

They communicate with one another over a combination of APIs, event streaming, and message brokers.

For a business, what this means is that: Application components can be developed and

updated more efficiently by multiple developers working independently.

Teams can use different stacks and runtime environments for different components.

Components facing too much load can be scaled independently, reducing the waste and cost

associated with having to scale entire applications.

In this video, we’ll look at how microservices have shaped application development, and also

look at a use case that illustrates microservices in action.

The way developers work to build applications is changing.

In the past, software was built as large monolithic applications where a team of developers would

take months to construct a large application built on a common code base.

These developers would write every part of the application from start to finish.

Now, after decades of software development, there are vast amounts of code already out

there that developers can use as the base of an application, meaning they no longer

have to create every line of code from scratch.

Cloud development platforms provide developers with an ecosystem of code that can be easily

and securely integrated into applications.

Now, instead of building one huge application on one team, developers break into small independent

teams where they write smaller amounts of code called microservices.

Microservices breakdown large applications into their core functions, for example, search,

recommendations, customer ratings, or product catalogs.

Each is developed independently of one another, yet work together on the cloud development

platform to create a functioning application.

A container is the distribution method for each microservice, meaning it delivers the

code where it needs to go.

Containers are plug-and-play, so if one microservice isn’t working for an application, developers

can take it out and put in a different one without disrupting how the rest of the app

functions.

Check out microservices in action with Ron.

Ron is a soccer fan who uses an online streaming media service called Dream Game.

Last night he missed watching his team play their crucial semi-final match.

Luckily, he can watch the game tonight with Dream Game.

When he logs in, he sees the most popular content among all Dream Game users.

After some searching, he finds the match he’s looking for.

What he would really like is to find his game with one click.

Luckily, the Dream Game development team is using microservices to develop a better user

experience for viewers like Ron.

The first microservice is a content catalog housing the millions of games that Dream Game

offers.

The small team of developers organizes each piece of content with metadata that describes

them.

This metadata feeds into a second microservice, the search function, which ensures that Ron’s

search results are captured and compared to the Dream Game catalog.

The third microservice, recommendations, captures data about the most popular content among

all Dream Game users.

This is what generates the home page that Ron saw when he first logged in.

These three microservices are all in their separate containers ready to join the application.

But before they can work together, they have to find one another.

They do this by using something called service discovery, which creates a roadmap for these

and many other microservices to communicate.

When microservices find each other, they communicate using an application programming interface

or an API.

So when Ron searches for his favorite soccer team, the search microservice is communicating

to the content catalog, in an API, about what Ron is looking for.

Now back to the goal at hand.

To get Ron to a soccer game with just one click, the development team working on the

recommendations microservice is updating the code, adding an analytics algorithm.

Using analytics, the recommendations microservice will compare Ron’s viewing history and preferences

to popular content among other users, including soccer fans and viewers in Ron’s geographical

region and demographic.

Since the developers didn’t need to create the code from scratch, they are able to deploy

this new functionality in a matter of days.

These updates happen behind the scenes as the rest of the microservice containers function

normally.

The next time Ron checks DreamGame, instead of just seeing the most popular or newest

content he sees a personalized playlist that will continue to refine itself as the system

learns more about his viewing habits and preferences.

The result, Ron finds his favorite team’s latest game right away.

The microservice approach lets developers quickly innovate applications in parallel

and lets users like Ron focus on the things that really interest them.

And when those interests are changing and growing faster every day, microservices help

businesses keep up and grow with their customers.

In the next video, we will talk about serverless computing, its features, benefits, and some

use cases.
