Monolithic to Microservices - The Rise of Serverless

The Rise of Serverless From Monolithic To Microservices

Software architecture patterns concentrate on the possibilities for higher-level application organisation. They offer best-practice solutions for some of the issues, including scalability, deplorability, and simplicity of maintenance. Common architectural designs make it simpler to grasp solutions since they adhere to a well-known pattern.

Choices Of Architectural Patterns

Let’s talk about some of the most common architectural styles. However, it is important to remember that systems may follow a combination of architectural patterns depending on the application’s requirements.

1. Monolithic Architecture

An application is monolithic if its features are contained within a single application. We must have all built a monolithic programme where we were given a problem statement and requested to create a system with various functions.

The coding for this application is divided into layers for appearance, service, and storage before releasing it as a monolithic jar or war file.

Advantages:

• It is comparatively easy to create compared to microservices.

• Deployment is simpler because only one jar or war file needs to be uploaded.

• Network speed and security issues are quite minor.

• Developers may retain their attention on a single application without having to master others.

Disadvantages:

• With time, it becomes huge and difficult to maintain.

• Even a minor modification requires a complete application installation.

• The application’s start-up and deployment times grow with its size.

• Even if a new developer’s role is limited to specific functionality, it can be quite challenging to understand the logic of a large monolithic application.

• The monolithic application, as a whole, can go down due to a single bug in any module, making it unreliable.

Ideal Use Case Scenarios:

While the parts of monolithic software are linked and dependent on one another, this is the best option for small projects not needing size and when the application’s size and scope are very limited.

Interrelated tasks can be handled by monolithic software. They often include several inseparably linked functions and are complicated applications such as monolithic software applications for online shopping.

2. Microservices

The microservices method primarily concentrates on business capabilities and goals. Each feature is developed and launched as a separate application that communicates with other applications via Application Programming Interfaces.

As more and more businesses migrate to becoming flexible and adopting automation, the microservices model has grown in popularity. Microservices are the best option when internet reach, adaptability, and simplicity of maintenance and deployment are required without sacrificing speed.

Advantages:

• Due to its relatively tiny size, it is simple to manage.

• You can implement microservices independently because they are self-sufficient, and their start-up periods are comparatively quicker.

• A new developer can join the project relatively easily because they only need to comprehend the specific microservice that provides the functionality they will be working on, not the entire system.

• Each microservice may utilise a different technology depending on the organisation’s needs.

• The entire system is unaffected, even if one microservice fails due to a defect.

Disadvantages:

• With an increase in the number of microservices, their complexity rises.

• Working with microservices architecture calls for skilled developers.

• Microservices consume a lot of network resources since they must communicate with one another remotely, which increases response time.

• Due to network-based inter-service communication, microservices are less secure than monolithic apps.

• Determining the cause and location of a mistake is a complex job when diagnosing because control flows across numerous microservices.

Ideal use case scenarios:

Currently used microservices architecture examples include Amazon, Netflix, Etsy, and Uber.

3. Serverless

Developers can create and run services using serverless architecture without worrying about maintaining the underlying infrastructure. In a serverless architecture, applications are hosted by a third-party service, cutting away from the requirement for the developer to handle server software and hardware. It can lessen your workload for tasks linked to architecture, such as provisioning, scaling, and maintenance.

Advantages:

• You don’t pay for servers or virtual machines that aren’t being used because you only pay for the requests.

• Within the restrictions of concurrency constraints, function instances are automatically added or withdrawn in response to fluctuations in traffic.

• Serverless technology enables programmers to immediately deploy their work without managing servers, accelerating delivery times and fostering rapid business expansion.

• High error tolerance because of the adaptable hardware setup in the provider’s data centres.

• Real-time, quick resource provision, especially for peak loads and disproportionate increases.

Disadvantages:

• No access to the operating system, runtime environment, or virtual machines.

• Implementing serverless structures is quite labour-intensive due to its intricate monitoring.

• Lock-in effect - a concept that implies having to recode all event-based procedures when changing providers.

• Due to the complex monitoring and debugging process, in-depth performance, error, and debugging evaluations are typically not achievable.

Ideal use case scenarios:

You can use serverless computing when several devices access different file types, such as mobile phones and PCs, and submit pictures, videos, and text files. Situations involving live video transmission are best served by serverless architecture.

Situations involving the Internet of Things (IoT) can use serverless architecture. A serverless design also makes constructing a shared delivery dispatch system simple.

Serverless - The Most Natural Solution To The Asynchronous World

All these architectural systems are important and must be implemented according to the needs. However, Serverless Workflow has the ability to call into Function Compute operations asynchronously. Asynchronous invocation is the best option in various situations, including manual audits and lengthy procedures. This can facilitate restart logic, streamline troubleshooting processes, and help you avoid throttling mistakes.
