Microservices have revolutionized the online world as we know it by increasing efficiency and making the development of agile systems a greater possibility than it ever was before. Microservices made fully monolithic structures outdated and reintroduced entirely new structures for websites and applications based on decoupling and hybridization instead. We now have entire teams in IT departments that are assigned to a single microservice. They can modify and update that service without any intervention and interference from the rest of the structure.
From Amazon to Netflix and eBay, all the tech giants and highly recognizable business online platforms heavily rely on microservices for their daily functions. However, microservices are by no means simply limited to just these giants, they can be utilized by smaller businesses and platforms as well, and all they really need is a good IT team.
The introduction and common use of microservices have enabled businesses to shift into much more agile systems, which offer endless advantages for both the consumer and the business itself. Like all other new technologies being used online, microservices consistently improve and update. However, there is no doubt that overall the transition has been highly advantageous and extremely innovative.
Benefits Of Microservices:
Microservices can be defined as one of the most innovative ideas of the 21st century. With the introduction of microservices, businesses were able to completely uproot their systems and put together an entirely new structure that only helped them become more efficient in the long run. Naturally, all of this happened because microservices have offered advantages to businesses that helped resolve all their concerns at the time. Some of these advantages include the following:
Since each microservice functions independently of all others, it is much easier to modify, update, and scale each microservice on its own than it is with tightly coupled, monolithic systems where the scaling of a single service requires disruption of the whole system.
This is especially beneficial since sometimes, a few components of a system need to be scaled higher or lower to accommodate the traffic and needs of the business and consumers instead of the entire system. Not only is this efficient and contributes to saving time and effort in an organization, but this also helps to save costs that would otherwise go into scaling up the entire system instead of the necessary components.
The failure of a single component in a decoupled architecture that uses microservices is most likely not going to affect any of the other microservices because each microservice is autonomous. Of course, some microservices are still dependent on each other as per the system’s requirements, and those could be affected, but there is very little chance of a fault or component failure making an entire system crash.
Despite the dependencies in a microservice architecture, developers can protect their own components once a fault is spotted. Cascading features that can shut down even loosely coupled systems as a component fails can also be prevented with the help of circuit breakers in the system. Many dependent services can also be reconfigured to be asynchronous to prevent these failures in the future, which was impossible in monolithic structures.
Connect Programming Languages
One of the best features of loosely coupled systems based on microservices is that they are programming language agnostic, which means they do not depend on the consistent use of a single language throughout the system. Developers in a team are easily able to connect microservices no matter what language they are in.
Similar to programming languages, even entirely different technologies can come together as one. So each team assigned to a microservice can easily choose different technologies for proper implementation and use of their services.
The connection of programming languages and technologies has helped pave the way for innovations that were impossible when tightly coupled systems were common. Developers can make use of different benefits and possibilities from technologies and languages and integrate them into a single system, which increases efficiency, agility, and the problem-solving capacity of each system.
The main problem with data security arises when different teams connect their microservices, and the data spillover could cause data and security breaches. However, this is where APIs come in. APIs that most developers use these days are secure and are able to prevent data breaches with ease. Secure APIs are able to safeguard the data by ensuring it is only available to authorized users.
Microservices that deal with sensitive data such as credit card information use APIs, which help provide developers with all the control regarding who gets to access which information.
Two-Pizza Development Teams
Amazon was the first to support two-pizza development teams. This term refers to teams being small enough to be fed by two pizzas. These small teams are easy to manage, show better teamwork, and are therefore more efficient. Additionally, they help to achieve objectives quickly and are able to deliver higher quality work in general. These advantages are mainly achieved due to the teams being so small that they can communicate effectively and generally form human bonds, which help them understand each other better.
In monolithic structures, much larger teams were required and, therefore, finding discrepancies in functionality and communication was much easier for them. It is harder for people in monolithic structures to trust each other as easily as they do in smaller teams and decoupled structures because only the component they are in charge of is dependent on them.
Microservices have been one of the most innovative solutions to grace the tech world in the previous decade. Microservices have helped to replace tightly-coupled monolithic structures with loosely coupled systems where a different team takes charge of each component of a platform, and this has been able to pave the way for much innovation in the present and future. Systems are now able to run more efficiently and quickly than they have ever before, and these decoupled systems are only set to improve and become more efficient in the future.
