Microservices: Legos for Software Development
We are so much in love with colourful plastic bricks aka LEGOs! In an age of online games and internet-connected toys, the humble Lego brick has risen against all odds.With approximately 62 pieces of Lego bricks for every man, woman and child on the face of the earth, mere 6 or 8 bricks can be combined in more than 915 million ways.
Counted among the most valuable toy brands in the world, Lego is not just anothermillennial fad but enjoys a huge fan base of children and adults alike. Countless benefits including improved motor skills, cognitive flexibility, spatial reasoning,engineering skills make it great for all ages and learning levels.
Building Software like LEGOs
After playing with Lego blocks for decades, one cannot help but wish to build applications by snapping together different components just like mixing and matching different plastic blocks to build a ship, car, high-rise building and what not. The flexible design capabilities of Lego paves way for incredible software development.
The only thing that limits you while playing with Legos is your own imagination. The tiny blocks, when put together in the right manner can help you build monster fighter planes to stunning replicas of monuments. At Zuse, we thought, “Why not do the same thing with our software”?
With the entry of Microservices in the tech industry, LEGO-based Software Development became a reality.
What are Microservices?
Microservices are a software development technique—a variant of the service-oriented architecture (SOA) architectural style that structures an application as a collection of loosely coupled services.
Adopting Microservice as a Design Standard
With the increased adoption of microservices as a design standard, our organization reaped numerous benefits of modular design. It helped us easily maintain and scale software as per usage and changing needs.
The biggest advantage of breaking down an application into independent services is improved modularity. It makes understanding, developing and testing an application a lot easier. Individual teams can easily develop, scale, deploy,and redeploy independent services to build new applications.
Microservices: The LEGO blocks for Software Development
To begin with, consider two scenarios:
- Building a structure using LEGOs
- Building a structure from scratch
Consider building a structure using Legos- with ready-to-use individual building blocks, the entire process is simplified as it helps you to build without much hassle. This is in stark contrast to building a structure from scratch wherein you would first need to build custom pieces and then assemble them into whatever you desire.
Just like Legos, Microservices are specialized building blocks with individual functionalities. The scalable blocks are typically combined via APIs and help break down huge enterprise solutions into smaller blocks that can be assembled as per your business requirement.
Why do we need Microservices?
With changing consumer needs, it has become imperative for organizations to cater to their needs in a more agile and reliable manner. Conventional monolithic applications require extensive validation and testing even for small changes and an outage affects the entire application. This is where microservices architecture steps in to address the drawbacks.
Leveraging microservices, an application is decentralized into separate entities. This ensures that even if one service crashes, the entire structure does not fail. Thus, enabling us to deploy business-critical services on multiple servers for increased availability and performance.
It helped us build, scale and innovate faster with increased business agility. With an aim to undergo digital transformation, Zuse rapidly adopted microservices to:
- Re-architect platforms
- Modernize legacy systems
- Discover new streams of revenue and growth
- Improved Scalability
- Faster time to market
- Easier debugging and maintenance
- Optimized resources
- Improved ROI
