Microservices: Challenges, Mistakes, and Learnings for the Future

Microservices are the architecture to build future expansion plans, but the decision-making and actual shift can be a bit overwhelming for the IT leaders. Here are some common concerns and myths about this migration, and guidance on how leaders can make this decision slightly less complicated

Oftentimes, the simple things around us can act as our greatest inspirations to bring about innovation. Take Lego building blocks for example – they let your imagination run far and wild with each piece that’s stacked on top of another. Each building block is unique, comes in different colors, and adds to the overall structure. And when you’re finished, this structure can be disassembled, and the same blocks can be assembled to create something new again! It’s amazing how much one can learn from simple exercises like these.

Microservices follow a similar approach to Lego blocks when it comes to building applications and IT infrastructure. It is not surprising that the IT and technology sector is one of the fastest-growing industries in the world. In fact, research reports state that the microservices category is projected to grow at a massive 22.5% every year, for the next five years. Every digital-first and agile enabled business today, whether it operates in IT or not, is making the move to microservices and letting go of age-old monolithic structures. Debates about the pros and cons for each continue to take center stage, as microservices is one of the hottest topics in developer discussions today.

The choice between sticking with monoliths vs adapting to microservices can indeed be a tricky one. Microservices offer users multiple benefits including modularization of components and individual services, efficient organization, and decoupling of units as per their need. This modernized approach also reduces the scope of error, since it is highly automated, more flexible in terms of developer onboarding, and processes easily scalable across the enterprise, which makes for massive cost savings.
