Microservices architecture, or simply microservices, is a method to broaden software frameworks or a single software as a collection of numerous small services. Developing single-function modules with well-defined APIs (Application Programming Interface) is the main target of microservices. Small, self-contained groups own these offerings.
Microservices essentially makes web applications or any applications for that matter easier to develop and simpler to scale. This type of microservices application development enables innovation quicker and more reliable delivery of complex applications.
Microservices has become a new trend and is increasingly popular as enterprises look to become more agile and evolve from a monolithic architecture where all processes are tightly knit and run as a single service.
The rate of microservices adoption is growing at a rapid pace as companies strive to take advantage of its increased agility and scalability. In this blog, we will look at the characteristics, pros and cons, and the microservices key trends that will emerge in the coming year.
Let us first have a brief look at the characteristics of web applications with microservices.
Built specially for businesses, each set meets a specific priority or solves a specific problem. Since small teams build different services, they can also focus on maintaining and running that service for its lifetime.
Independence from a tightly coupled program, microservices architecture enables the development of each component without affecting the functioning of another. In this state of autonomy, service teams need not share any code or implementation process, thereby plugging any communication gap.
Simplicity in developing and maintaining is why microservices are becoming popular with each passing day. By definition, any software built with microservices architecture can be broken down into multiple components. This feature makes it easier to modify or improvise on any component in isolation and redeploy the entire software without worrying about other affected components.
Evolutionary design is one of the most significant advantages of microservices architecture. Large systems that once had complex monolithic structures will become more scalable and agile if broken down into smaller, easier to run microservices thanks to emerging technologies.
Advantages of Microservices
° A relatively smaller group develops and designs microservices and runs and maintains each set without interference from the other.
° Simplified development and approach to microservices architecture will help newer team members understand the system fairly quickly, reducing hand-holding time and facilitating a more efficient workspace.
° It is easier to modify and improve microservices architecture than a monolithic (and almost outdated) program. Changes required in only one part of the application can be made without disturbing the other areas.
° Similarly, if one microservice malfunctions, it will not stop the entire operation as the others will continue to work.
° Easy to integrate with third-party services.
Drawbacks of Microservices
° Quality testing becomes a time-consuming and tedious task due to distributed deployment of each service.
° The system will increase chances of duplication as more small services designed by different teams are later bunched together.
° It can be very complicated to integrate and manage the entire set if the number of services increases substantially.
° Use cases that utilize overlapping microservices can be complex as several teams are involved in one use case.
Top Trends of 2022
The following are likely to be the top microservices trends of the coming year. Let us take a look at them.
1. High microservice market growth
According to a report by Allied Market Research, the global microservices architecture market size estimates to reach $8073 million by 2026, registering a CAGR of 18.6% from 2019 to 2026.
With the increase in use of connected devices like smartwatches, tablets, fitness trackers, SaaS, and PaaS-based enterprises have rapidly adopted cloud-based solutions. These are the key components driving microservices consulting a high market growth rate.
Enterprises are rapidly moving towards microservices architecture catering to end users in several industries. These may include retail, healthcare, IT and ITeS and telecommunications to provide solutions at their fingertips.’
In other words, the solutions segment – across industries – has seen the highest growth owing to the adoption of microservices architecture by businesses that are high on customer success. The widespread acceptance of microservices as the next big thing to help streamline web applications development processes is helping organizations with faster development cycles, scalable and agile systems and improves productivity with reduced costs.
2. Cloud Adoption
Growing popularity of cloud-based applications is offering more opportunities for customer-oriented businesses. Even as the pandemic accelerated cloud adoption, we are no strangers to the increasing dependence on cloud solutions in modern workplaces.
Organizations are going ahead and transitioning to the multi-cloud strategy using the microservices architecture. While taking care of specific organizational needs, this approach also proves cost-effective. It also helps avoid dependence on a single source of software development as microservices are essentially smaller components pieced together to make an extensive software program.
A report by Gartner predicts that by 2025, 90% of businesses will adopt a multi-cloud approach to run their businesses more efficiently and with reduced costs. Enterprise mobility will be another advantage for most enterprises as cloud adoption via microservices architecture will provide the necessary connectivity, agility, and scalability.
However, businesses must optimize their costs, especially while adopting the multi-cloud approach. While a particular mix of microservice architecture and cloud adoption will help cut costs, it is essential to know that public cloud adoption expenses can quickly spiral and are hard to control if not monitored closely. Careful management is the key to keeping the costs in check.
3. Observability Tools
After setting up a microservices architecture for an enterprise, the next step is to identify tools that help check its health. There might be several operational challenges in the said system that must be resolved to give the end-user a seamless experience. A robust observability framework is vital for smooth running of your system.
The year 2022 will see a growth in tools that will help keep track of logs, metrics and traces of an organization’s microservices data. Several APM (Application Performance Management) tools will help developer teams understand telemetry data, storage backend, and microservices deployment.
Here are a few tools that can be used to keep track of your microservices architecture health:
° Grafana Labs
° New Relic

4. Frameworks for web services
It is crucial to choose an appropriate framework to develop microservices architecture for an enterprise. While selecting, developers will highlight the aspects that should be considered as a trend the coming year.
As a developer, you must keep in mind the criteria for selecting a suitable framework. Identifying the application’s requirements, planning and organizing its segments into smaller functions is the first step in the direction. A framework should be selected without changing its core features, considering that the application needs to be subdivided into individual components.
Appointing teams that can work independently but collaborate on a need basis is another critical requirement to choose the best framework. The groups should have the required skills and tools for developing, deploying, and managing their specified service.
Here are some popular microservices frameworks that can be deployed for efficient microservices architecture:
° Spring Boot
° Eclipse Vert.X
° Oracle Helidon
5. Increased demand to update applications
While the need to constantly update applications to meet increased user demands is not something we are unaware of, this may be a significant challenge for organizations. This happens if they are not prepared for round-the-clock work on updating the applications for rich and dynamic experiences.
Regular updates help businesses get more mindshare, build a loyal user base, fix tiny bugs, improve designs, and provide better features. It also overall enhances the user’s experience.
At the onset, microservices architecture can be developed to support this demand for frequent updating. Developers can use the Autonomic Computing framework so that the system can work on its own with minimal to no human intervention. Once set up, there is no need for manual intervention to optimize, configure or update a system or application.
Microservices is here to stay!
For better or for worse, microservices have become the default choice for many, if not all businesses. In the case of enterprises with independent teams, microservices architecture can work well in the larger sense. However, the downside is that it is not without its complications that a distributed system brings.
As far as the current and future trend in microservice architecture is concerned, it is a great time to be around! A trend that will also pick up soon is the shift towards serverless computing. While Microservice has existed for over a decade, it is only now that enterprises are beginning to embrace its benefits. With no burden of infrastructure management, saving on costs is an added advantage. Serverless computing can also eliminate maintenance problems with a more traditional framework.
