Getting Started with Microservices: An In-Depth Overview

Delivering Today's Success with Tomorrow's Technology
Get a comprehensive look at microservices architecture—its evolution, key features, benefits, and important considerations for effective implementation.
People often say that breaking a big problem into smaller, manageable parts is the best way to tackle it. This idea has greatly influenced how technology has developed.
In the past, everything was built as one large system with all parts tightly connected. This approach is known as Monolithic Architecture.
So, if one part of the application experienced high demand, the entire system needed to be scaled up.
As the codebase grew, adding new features or making improvements became more challenging.
Plus, if one part failed, it could affect the entire application, increasing the risk of downtime.
For example, Enterprise Resource Planning (ERP) systems were often built this way, handling various tasks like finances, supply chains, and human resources.
These monolithic ERP systems were large and complex, making them difficult to maintain and enhance.
As technology advanced, a new approach called Service-Oriented Architecture (SOA) emerged, making it easier for different systems to work together.?
This framework improved and evolved into what we now call the microservices architecture. With microservices, software is divided into smaller, independent parts that are easier to manage and scale.
About the Microservices Architecture
Microservices architecture refers to an architectural and organizational style for developing software. It’s a way of building applications by breaking them down into smaller, separate services or microservices.?
Each service is developed, deployed, and managed on its own, making it easier to work on different parts of the application independently. These services are owned by small, self-contained teams.
Characteristics of the Microservices Architecture
Here are some of the main features of microservices:
Is the Microservices Architecture Right for Every Enterprise App?
Microservices architecture isn't a one-size-fits-all solution for enterprise apps.?

It's ideal for complex, large-scale systems that need to handle numerous complex functions, a lot of data, and frequent updates, like financial services or e-commerce sites.?
These apps benefit from microservices because they can scale different parts independently, update features faster, and isolate faults better.
On the other hand, simpler or smaller applications that don’t need extensive scalability or have less complexity might be better off with traditional monolithic architectures.?
Monolithic systems can be easier to manage and more cost-effective in these cases. The choice between microservices and a monolithic approach should be based on the app's specific needs, size, and future growth.?
This way, the architecture chosen will fit well with the app's goals and requirements.
Commenting on the topic, Himanshu Gupta, Chief Operating Officer (COO), iorta Technology Solutions, says, ‘When appropriate and feasible, microservices revolutionise the way we build and scale applications, empowering teams to innovate and deliver value faster. By embracing the principles of modularity, flexibility, and distributed systems, organisations can unlock the true potential of microservices architecture and drive digital transformation in today's dynamic world.’
Real-World Use Case: How Amazon Uses Microservices
A great example of a company that successfully implemented microservices is Amazon.?
In the early days, Amazon’s website was built using a monolithic architecture. As the platform grew, the codebase became harder to manage, and the system started struggling under heavy loads, especially during peak shopping times like Black Friday.
To fix this, Amazon shifted to a microservices architecture.?
They broke down their system into hundreds of small, independent services—each responsible for specific tasks, like managing the shopping cart, user recommendations, or payment processing.
With microservices, Amazon can now scale individual services to handle high traffic during peak times without affecting other parts of the system. For example, if the payment service needs more capacity during a sale, they can scale it independently without scaling the entire platform.?
This switch has allowed Amazon to handle millions of transactions smoothly while adding new features faster.
Limitations of the Microservices Architecture
The microservices architecture is not all sunshine and roses.?
It comes with unique challenges that arise due to this architecture raising the complexity levels across various areas of software development. Let's consider a few of them.?
System Design: The design phase involves breaking down an application into more minor, loosely-coupled, independent services and defining their boundaries, dependencies, and interactions.??
Doing so is a complex task since it requires careful consideration of service responsibilities, communication protocols, data flow, and Continuous Integration and Continuous Delivery (CI/CD) plans.??
If said so simply, the higher the number of services, types of technology stacks, and dependencies, the higher the complexity.
Data Consistency: Each service manages its data independently in a microservices architecture. This characteristic can lead to the problem of data redundancy, where the same data could be stored by multiple services for different purposes, like reporting or analytics.?
Managing these data relationships can be tricky and may need new approaches beyond traditional methods.
Testing and Debugging: With many services running in different languages, testing and debugging can be tough. Debugging failures requires analyzing distributed logs (across services), and failures can have cascading effects due to interdependencies between services.?
Effective testing must consider both individual services and their integration.
Maintenance: Using different technologies for each service can increase maintenance costs. Managing multiple tools and technologies can sometimes be more expensive than sticking to a single approach.
To conclude, adopting a microservices architecture comes with a host of benefits that can help you build and deliver software faster and enable you to experiment and embrace a fail-fast approach.?
However, microservices do raise complexity levels and require careful construction and design of the architecture, so do think it through.

4 周Microservices is a failed concept, as per Netflix, as its turning into Modularized Monolithic... #Iorta can experiment set of microservices for their #HR, #Admin...etc as internal product and realize how much maintenance overhead adds up, also whats the grade of Devops, Gateways should be available inorder to scale as per theories... I can help, as an Architect!
