🛠️ Microservices Architecture Overview
Microservices architecture is a method where a single application is divided into smaller, loosely coupled components or services that can be independently developed and deployed. Each service operates in its own container and communicates via APIs, event streaming, or message brokers. This approach allows for efficient development and updates by multiple teams, the use of different technologies for different components, and the ability to scale specific parts of an application as needed. The video discusses how microservices have changed application development from monolithic applications to a more modular approach, utilizing cloud platforms and containers for distribution. An example is given with 'Dream Game', an online streaming service, where microservices are used to create a personalized user experience.
🌟 Microservices in Action: Personalized User Experience
The script describes a scenario where 'Dream Game', an online streaming service, uses microservices to enhance user experience. Microservices such as content catalog, search function, and recommendations work in separate containers and communicate through service discovery and APIs. The development team is updating the recommendations microservice to include an analytics algorithm, allowing it to provide a personalized playlist for users like Ron, who can then find his favorite soccer team's games more easily. This showcases how microservices enable rapid innovation and the ability to update applications without disrupting the user experience.

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.
