Microservices & APIs |
Microservices are a way of structuring applications as a collection of services. They are used to signify small, self-contained, and programmed services that are used to do a single operation. Due to this, large and complex applications can be made quickly, periodically, and dependably. Due to their efficiency, microservices are used by almost three-quarters of organizations. Why exactly have microservices become so popular? What benefits does it entail? And why should businesses use microservices? Let’s find out.
Traditional business operations were done through a single autonomous unit that was in control of everything. On the other hand, microservices consist of a system of applications that can be tested, developed, and deployed independently of each other. This means that complex and large applications can be compartmentalized into smaller parts. These small blocks are much more efficient at communication due to the use of Application Programming Interfaces (APIs). Another point in favor of microservice is that each unit in a microservice suite is self-contained. This means that developers can work on a particular service without interfering with the others, thus always maintaining the functionality of the whole application.
Benefits of Microservices
In a single, giant application unit, all the components are interdependent and connected. This means that any new addition or update will require an explicit understanding of all other components of the application. It will ultimately require that the whole developer team get involved in making a single update. When this happens on a large scale, it can impact the delivery time and the workflow of the business.
Microservices, on the other hand, are made up of independent suits that keep the development environment streamlined. This means that small teams can update and make changes to individual components simultaneously. As a result, developers have more autonomy and aren’t left waiting for other teams to complete their work, thus driving up productivity.
In a microservice architect, every individual component of the application can be made using a different programming language. This provides businesses more flexibility when it comes to choosing the best developer to work on it or choosing the best component for a function. This versatile nature of microservices increases the ease of deployment of the application. This, in turn, encourages experimentation with new technology to fill up old gaps. Ultimately, this reduces the risk of your application becoming obsolete with the passing of time.
As each component of a microservice suite can be individually tested and deployed, it becomes easier to scale the software. Without worrying about limitations like bottlenecks, a microservice architecture can be scaled at any pace as needed. Since they are easy to replicate, adding new resources as needed is relatively simple.
In a monolithic appreciation pattern, even a minute and small error can cause problems for the whole system. This can result in a major headache for companies and incur high costs. In microservices patterns, such a scenario is highly unlikely. Even if there is a failure, it will only be limited to a single component. In the worst-case scenario, multiple errors can occur in different compartments. But even that is highly unlikely to compromise the whole application.
This independent and component system of microservices leads to a drastic reduction in the risk associated with errors and bugs. Corollary leads to fewer costs incurred to fix these problems. In case of problems, developers can simply work on one service. Or they can just roll back volatile updates without risking the entire application.
Microservices break down large applications into smaller and simpler parts. But what if you’re not working with a complex and large application? In most cases, the cost and maintenance associated with microservices will likely offset any benefits of upgrading. Generally, small application systems work just fine without microservices before upgrading. It is essential to know whether such an upgrade is required or not. If you’re a new business, it’d be better to start with a monolithic application and then scale to microservices when the volume becomes large.
Microservices need small and independent teams to work on individual components. While this results in increased productivity, it also limits the field of vision of the workers. By staying fully focused on their solution, they can often miss the bigger picture. In addition, these small teams will also need the expertise to manage end-to-end processes. This is why good communication between each team is vital, especially when working with distributed teams. Organizations with poor communication lines between different departments may find it difficult to adopt microservices. A way to overcome this is to deploy the agile methodology that is a natural fit for microservices.
The individual nature of microservices means that there are more ways to attack the system. It inevitably increases the vulnerabilities in a system due to its distributed nature. Protection against cyberattacks is essential for any software system, so when upgrading to microservices, security is a primary concern. These risks can be dealt with using firewalls, API gateways, and multi-factor authentication. It’d also be wise to assess any risk to the microservice system before its deployment. Adopt a long-term approach and make security a core feature of the design.
Focaloid understands that the architecture of a system can affect the viability of the platform. This is why our developers spend plenty of time understanding the client’s time, cost, and performance needs before coming to the right solution. Our experts have already supported several organizations’ shift to microservices. We have extensive experience in designing and implementing microservices while leveraging the benefits of technologies like agile and DevOps.
The modular nature of microservices has plenty of benefits like scalability, flexibility, and quality. When best practices are applied to the system, microservices systems can generate huge returns on investment. However, before shifting to such a system., it is vital that you understand and analyze why it is needed. There is also a need to ensure that the project manager can handle its end-to-end oriented design. Its distinct features and functionality mean that it is essential to understand its nuances. Only those who do will be able to leverage the full potential of this technology.
