8 Benefits of Microservices Architecture for Business

Microservices architecture is a proven approach to drive scalability, resilience, and agility to your business application.

According to the survey conducted by IBM Market Development & Insights to study the business advantages of microservices, 87% of IT executives and tech specialists believe that the efforts and cost of microservices adoption are worth it.

In this blog post, we talk about the key advantages of adopting microservices architecture and name a few baseline business cases for this approach. You will also learn about the challenges related to this model and the cons of microservices to think of before choosing this approach for your project.

Briefly about microservices architecture

Microservices architecture is a modern approach to building software applications out of a collection of individual modules (services). Each service is usually focused on performing a specific task (payment, shipping, etc.) or business function and can be developed with a custom set of technologies.

This provides agility both for the engineering teams and for the business itself. For instance, microservices-based applications are easier to scale. Individual services are often faster to develop and deploy compared to monolithic applications. And the list of microservices advantages only starts here.

Let’s drill into these and many other benefits of microservices. You'll see how this approach helps companies build sustainable and high-performing applications, fast-track time to market, and effectively adapt to changes.

8 microservices benefits that impact your key business goals

Flexible approach to the choice of the tech stack

Each module in microservices works like a small application and thus can be built with a custom set of technologies. This tech-agnostic approach allows business and engineering teams to select the stack that would work best for each component. As a result, they avoid unnecessary tradeoffs caused by the incompatibility of some technologies or ageing stack.

Effective migration and upgrade

The ability to quickly migrate to newer technologies is some of the important microservices benefits for fast-evolving applications. Companies can easier switch to the latest frameworks or tools when they deal with individual components. Instead of rewriting the code for a large system, engineers develop and support smaller parts and can effectively upgrade on demand.

Needless to say, opting for microservices is a proven way to avoid technical debt and related expenses for large-scale modernization projects.

Better scalability

Undoubtedly, one of the strongest advantages of microservices architecture is unparalleled scalability and capacity to grow. Autonomous services can be scaled individually depending on the load and processing power requirements without affecting other services and inflating the cost of scalability.

It’s also easier and more cost-efficient to add new services and features to a modular system rather than to scale an entire monolith. Moreover, the risk of compromising system integrity is low since services are containerized, loosely coupled, and often have different logic.

Improved agility and time-to-market

On the other hand, services can be scaled unevenly. This helps companies better allocate time and resources and focus on developing the functionality that reflects current business goals and changing market needs. Eventually, this results in significant savings. Instead of investing in full-scale development of a large system, businesses can prioritize and keep a laser focus on critical modules and business functions.

High maintainability and automated deployment

The microservices ecosystem is easier to support and maintain thanks to the increased autonomy of different components. Every service can be updated frequently and deployed independently of other services. Modern DevOps tools and CI/CD practices for automated deployment allow to adjust this process to the changing needs of each team. This makes application development and deployment effective and error-free.

Reliability and reduced security risks

The structure of a modular system is reliable and stable because services are isolated. Should any error or security issue occur in one service, it won’t affect the performance of other components and therefore won’t cause a major problem for the system as a whole.

Along with other benefits of microservices architecture, this advantage makes microservices an obvious choice for modern business applications that have high security and operation requirements.

Optimized development time and cost

Despite significant costs associated with setting up an agile team and microservices infrastructure, this approach is widely recognized as a source of significant savings, especially in the long run. We have already mentioned several benefits that directly impact the bottom line – faster time to market, reduced costs for upgrading and scaling the system, etc.

Additionally, the flexible nature of microservices reflects on the team structure. It allows to leverage dedicated team model and build agile teams – in-house and remote – responsible for specific modules or business functions. These teams can work in parallel thus boosting productivity and delivery speed.

Attractive for engineers

The last but not least point that supports microservices architecture advantages is high team satisfaction and a better chance to find top-tier engineers for app development. Generally, engineers are more likely to choose to work with a modern stack. Microservices is a modern approach that is associated with the latest engineering practices and developer tools. This alone is an important advantage for attracting strong specialists for the project.

This benefit is becoming increasingly relevant amid the growing shortage of tech specialists. Nowadays, this is one of the biggest issues that prevent companies from developing and scaling their systems as fast as they would want to.

Cons of microservices to consider

advantages of microservices architecture

Just like with any other architectural approach, you should consider both pros and cons of microservices before opting for this strategy. Adoption of microservices, especially on projects that require large-scale re-architecture and migration from monolith, is often associated with certain challenges such as lack of in-house expertise, considerable upfront costs, and a range of uncertainties related to planning and data strategy.

Here are a few cons of microservices and common challenges that result from them.

Expertise shortage

Lack of relevant experience in the company can be a real challenge that may stall the project. Microservices development isn't possible without relevant expertise in software architecture, infrastructure maintenance (DevOps) and agile development. Many companies simply don't have that at the start.

Hiring an experienced microservices development company is a viable strategy to solve this problem and kick off the project with a skilled cross-functional team from day one.

Timeline and costs uncertainty

It can be problematic for a business to assess how to break down the system into modules, separate workflows, and work out an effective data strategy and security layers. There also may be uncertainties related to estimating the costs and timeline for migrating to microservices.

advantages of microservices challenge

In-depth technology analysis is a proven way to cope with these uncertainties and develop the vision of the future microservices-based system as well as related documentation (tech stack, architectural diagram, specifications, etc.).

Increasing complexity

API-driven service-oriented architecture has many structural parts. Therefore, it takes more resources to support the system and keep it running. It may also require a more complex testing strategy as services have little in common and require individual testing and debugging.

Despite these challenges, multiple advantages of microservices as well as real-world experience and proven bottom-line benefits encourage companies to shift towards microservices and further invest in this approach.
