The digital economy is booming at a significant pace. Cloud-based applications, Big Data integrations, and API has completely revolutionized the digital market. In such a competitive world, businesses have yet not leverage such technologies that can create and compose several services into working distributed apps.

Microservices Architecture has emerged as the most trending service for app modernization. For one thing, they are cost-efficient and often popularly used by small-sized companies.

Such a service is architected differently than a monolithic application, making us think about scalability. Formulating effective strategies for protecting your microservice-based apps from any type of unforeseen failure is crucial, to making your app resilient and robust.

**Some of the issues with Microservices Architecture are as under –:**

- Hard and slow to maintain and test.
- Fixing a feature with bugs or under maintenance represents downtime for an entire app.
- Difficulty in managing and integrating with different languages.

## **What do you mean by Microservice Scalability?**

Think of your last visit to any online store. You must have used the search bar for browsing the collections. So, that site’s search bar represents a service. 

You might have also been suggested some related or complementary products while adding a product to your shopping cart. These are also called services. Now, when you have all these microservices together, you can form a fully functioning app.

——————

Microservice Architecture is a way of developing apps wherein every component, module, or function fits perfectly into a separate program. It allows a large app to be separated into smaller independent parts where every part will perform its responsibility.

So if you want to serve a single user request, the microservice-based app can connect with various internal microservices for composing the response at the helm. 

Such apps have their database and communicate with our microservices through APIs. They do not depend on any one particular language level of communication.

## **What is microservices architecture used for?**

Microservices are used for improving the speed of your app development. Such an architecture is built within Java, especially with Spring Boot. Some of the real-life examples of Microsoft architecture are -:

**1. Media content**

You should leverage microservice architecture, videos, and image assets that are kept in a scalable object storage system. These assets are served directly to the mobile or web.

**2. Transactions and invoices**

The order process and payments can be divided as independent units for accepting payment when the invoicing system isn’t working.

**3. Data processing**

A microservices platform can outspread cloud support for prevailing modular data processing solutions.

Leading online companies such as Amazon, eBay, Netflix, PayPal, Twitter, and Uber have dropped monolithic architectures and opted for microservices for scalability.

## **Perks of Microservice Architecture for your application**

The design choices often separate the microservices from monolithic apps. Some of the perks that microservice architecture offers are -:

- **Integration**: Owing to modularity, microservices can interact with the client side without communicating with any other microservice first. Moreover, microservices are language agnostic, which means that they can interact with each other without any problem irrespective of which language they’re written in.
- **Fault tolerance**: Their independence characteristics guarantee that any fault in one microservice won’t make another fail.
- **Maintenance**: Microservice-based apps are easier to fix after specifying the size of their code and independent diagnosis. However, such systems can be upheld and sustained with short downtimes before re-deployment it again.

Nevertheless, the most integral element of microservices is **scalability**.

## **Real-Life Example of Microservice Architecture - The Amazon Case Study**

- **Challenges:**

The customer base of Amazon was growing significantly in the early 2000s. However, the team of developers wasn’t able to keep up. This led to delays in service and projected coding challenges to meet the scaling requirements of the customer base.

- **Solution:**

So, Amazon divided its monolithic applications into small, and independent apps to resolve the issue and effectively managed the demand. It all began with analyzing the source code and separating the units of code into a single function.

- **Implementation:**

For instance, one single service was developed to integrate the ‘**Buy**’ button on the product page. Similarly, another service was developed for a ‘**tax calculator’** and finally, every independent service was allocated to developers. This gave them a detailed view of bottlenecks so they can overcome them with swift and effective resolutions.

## **What does a scalable web application mean?**

A scalable web app comes into the picture when there’s a sudden rise in the no. of users. The main objective behind developing scalable apps is to improve the speed and performance of the app without disrupting the end-user experience at a time when unprecedented traffic increases on your app.

Scaling web applications will help you to manage the requests per minute more effectively. Before deciding on developing scalable apps for your business, it’s important to consider certain factors like - the scaling metrics and costs of scaling. Such factors will maintain the feasibility of scaling web applications.

You can also leverage some of the modern technologies like **PWA, microservices architecture, caching, cloud storage**, and more to improve the performance of an application.

----------------

When the demand for apps starts rising, you’ll realize the requirement of maintaining the capacity, accessibility, and uptime of an app. So, how would you scale?

➡️ **Horizontal Scaling**

Horizontal scaling refers to dividing the load between the servers. Here, you can add more instances of machines without making any changes to the existing specification. You can consider horizontal scaling when you want to add horsepower. It's more like adding another vehicle to your fleet.

➡️ **Vertical Scaling**

Vertical Scaling is all about adding more support to your system so it can meet the existing and augmented demand. It refers to adding more power to your existing machines, unlike horizontal scaling where more machines are added to the system. So, if your server demands additional power, you can upgrade your CPUs and scale up the network speed, memory, and storage space.

## **The Final Words**

Microservice Architecture follows an efficient approach toward app development. It allows each core function to work independently within an application.

We know that you have worked hard on your application development. Now it’s the time to roll it into the market with the best-of-the-class strategy. So, are you ready to handle the staggering growth of your business?
