SaaS enterprises are now operating more functions in the cloud to drive cost, resilience, scale, and agility. The key enabler for this trend is Microservice-based architecture, becoming one of the top patterns for creating modern applications that scale efficiently and support agile and DevOps practices.


Culture change enables organizations to maintain the pace of business change and demanding market dynamics. However, to achieve the desired success, they need to build the proper roadmap for the change, set up realistic goals, create protocols, and address the forthcoming changes. Microservices architecture is one such change organizations need to adapt to. The shift from a traditional monolithic architecture to microservices allows quick delivery of new features and capabilities in response to disruptive forces. Therefore, businesses that aim to maximize resilience and ROI must embrace the microservices method in their business strategy for better agility and growth.

Key Areas to Focus

Risks associated with the change
Many enterprises realized the importance of culture change and invested in modern tools and practices that maximize their readiness for change amid the pandemic disruptions. Making resilience and adaptability the primary goals, they unlocked the potential of proactive innovation with microservices architecture by eliminating the risks concerning the change.

Team Collaboration
The velocity of business change and the criticality of business results in delayed responses have generated a new paradigm in which neither technology nor business professionals can achieve critical business goals alone. Therefore, many businesses initiated a collaboration process to meet the continuously accelerating demand for change.

The suite of business capabilities
Microservices architecture creates a way for new innovative approaches with API management. It upscales application modularity to represent business capabilities packaged with APIs and event topics for complete programmatic access.

Microservices To Power Your Digital Business

Embracing microservices architecture enables the organization to reap multiple benefits with the right approach. Hence companies heading to adopt microservices need to set up apparent expectations by determining the objectives based on cost analysis of the architecture. Then, upon the research, enhance the business outcomes through protocols of where, how, and when the team should leverage microservices architecture. Finally, focus on addressing the change through team alignment, investing in distributed computing architecture expertise, and enhancing DevOps practices for better results.

Analyze Cost-benefits Before Starting The Journey

Microservices can positively impact your business growth when deployed in the right way. However, before adopting, businesses should define the articulation of reasons to embrace the architecture. In addition, it should cover the whole business landscape, including the guidelines, technologies, methodologies, and modular style of system development. Finally, examine the operational components of microservices architecture, such as containers and service discovery, to manage the risks of initiating microservice architecture in your organization.

Microservices for SaaS Companies – What to Expect?

Microservice architecture has been around for quite some time now, but in recent years, mainstream software development has started to take them seriously. So it is evident that more and more companies are adopting microservices, especially in online applications where scaling can be challenging with traditional architectures. Today, online companies rely on DevOps culture more than ever before. Moreover, the DevOps movement has paved the way for development teams to adopt the microservices architecture. With Android, iOS, and other platforms as competition, there are many reasons why companies should start thinking about adopting microservices.

Deployment of Microservices Protocols to Application Architecture for Solving the Shortcomings of Monolithic

Microservices are broken up into modules that contain the microservice and its dependencies. Each service is independent of the other, which allows it to be scaled with ease.  Microservices are also self-contained and only include the logic necessary to perform their task.  They can be developed in any programming language, regardless of technical skill level, as long as it supports JSON.

There are many benefits to using a microservice architecture over a monolithic approach:

Smaller size: A microservice is small and easy to scale and maintain.

Scalability: Microservices can be scaled horizontally and vertically, depending on the size needed to meet an application's demand.

Deployment speed: Deploying and updating microservices is much faster than a monolithic architecture.

Lean development and testing: Microservices are more accessible to build than monolithic applications since each service contains what it needs.  Creating a single Microservice is much simpler as well since there are no dependencies required from other components.  The only thing you require to focus on is your Microservice and any dependencies it has.

Separation of concerns: Microservices provide separation of situations because they are designed to be self-contained and provide the required applications and services.

Inter-process communication: Microservices allow us to communicate securely between other clouds or systems.

Faster development cycles: The structure of Microservices allows us to develop them faster since we don't have to go through building and testing every piece of code within a monolithic application.

Deployment flexibility: Deploying a Microservice is easier because it can be deployed as a Docker container.

Security and privacy: By allowing services to be distributed across multiple clouds and platforms and by being self-contained, the security of your sensitive data is better protected with Microservices.

Microservices Enable a Revolutionary Pragmatic Winning Approach

Microservices is a software development approach that allows developers to build and deploy applications as independent services. This design-driven approach has helped organizations evolve into a distributed system of independently scalable microservices consumed by end-users through APIs. They can be triggered into action via triggers such as events, alarms, or messages. When this is the case, microservices may output streaming data for consumption by other microservices, which can immediately impact product features and end-user experience. As a result, microservices architectures often require a distributed stream processing engine to support the real-time processing of data for critical business events and scenarios.  Microservices are inherently flexible and can be adapted to meet the needs of an organization. However, this flexibility can also become a highway to complexity when managing microservice dependencies, infrastructures, and log management. This can lead to different teams creating microservices that integrate with varying components of the system. Therefore, careful consideration is required to overcome the risks.

Fortunately, microservices are often used to evolve an organization's IT architecture, and it is essential to be aware of this evolution as it happens. Unfortunately, this evolution can often lead to problems and misunderstandings. Therefore, it would be helpful to understand how microservices can enable smooth adoption and what an organization needs to consider as it evolves. Additionally, microservices may override API endpoints, leading developers to try and integrate their API calls into the existing system, making the integration process more accessible than initially intended. The initial development environment would be wildly different than a production environment due to individual teams using their tooling, testing process, and deployment routine.


Microservice is the best fit for businesses that looks for an API mediation strategy. With microservice architectures, each microservice is responsible for particular business functionality. To ensure secure and stable operations with the optimum advantages, Organizations must choose the right and trustable service provider to modernize applications by implementing suitable Microservices Architecture. The main reason for choosing a microservices architecture is that you can scale it separately; then, if one of them is not performing as expected, you can scale it out or put it in maintenance mode. You can test and deploy new microservices very quickly as well. If you follow the principles of continuous delivery, using microservices will make your life even more accessible.

Microservices bring several advanced features to the enterprises

· Cross-Functional Team with collaboration:

Servant leadership enables teams to collaborate and share ideas while making important decisions better.

· Synchronized Business Capability

Reusability of processes by aligning the teams based on skillset and distributing them for cross-functional activities.

· Shared environment

The ease of accessibility with microservices in development, deployment, and management allows different teams to distribute knowledge in a shared environment for better business results.

· Scalability and Reliability: Microservices support modern technologies to solve the shortcomings of monolithic. This leads to better scalability with enhanced efficiencies.

Organizations should take advantage of the microservices-based architecture to continue excel in quality and velocity in the long run.
