Have you ever had?

Shutting down the system while introducing new features? Long deployment times? Difficulties with adding new features? Dealing with cast databases? Single mistake could have caused expensive downtime of the whole system? Couldn’t handle the dynamic rise in traffic to the site? Low stability of the whole system during deployment?

That means, you may have experienced unsufficient technology.

Using a microservices approach to application development can improve resilience and expedite your time to market, but breaking apps into small services offers complications. You need skilled team like ours to pull it off.

Where is the problem?

The problems arise when it comes to scaling the business as the code gets more complicated, the architecture more complex, and more developers are needed just for the maintenance processes.

Monolithic systems were convenient at the start but turned out to be insufficient for scaling up business. Amazon, Netflix, Coca Cola, Uber, or Zalando already know what the microservices are all about. These global leaders typically started using a monolithic architecture because, in the initial phase of projects, it is much faster to set up and get the business running.

At some point, monolithic architecture becomes an obstacle standing in the way of growth.

Expanding a business requires breaking the boundaries, experimenting, changing, and risk-taking; keeping the status quo means simply going backward. But with a team of a few dozen engineers and extremely sophisticated business rules and thousands of lines of code—which is how it looks with robust monoliths—it is extremely hard.:

What benefits you will get?

Only possible way to easy scale your business

Expanding the system with a microservice approach is more like budding in your business, which gives you natural growth without losing the quality of the product and customers.

Business constancy

With the microservices approach, all business features are granularly split into separate micro-applications, even when migrating from monolith architecture to microservices. Each can be developed, tested, and deployed separately and without shutting down the whole system or risking losing stability.

Faster time to market

Leveraging a decentralized development process, you can test out ideas in a short time and introduce innovative solutions to customers before your competitors. What’s more, by promoting teams whose features are published for production, you can raise their accountability, effectiveness, and engagement.

Domain expertise

Microservices allow you to have separate services for things like promotions, checkouts, or product catalogs. Each can be continuously improved by a dedicated development team with business analysts and developers on board. Such an approach builds engagement of the team and speeds up development and innovations.

Simpler knowledge transfer

Leveraging the Single Responsibility Principle means that a single microservice only performs one business function. Therefore, developers can create more efficient, clear, and testable code. The overall microservices architecture is much easier to understand so even new developers can maintain or modify it quickly and with fewer mistakes.

Easier outsourcing

With the microservices approach, all services are separable and relations between them usually have to be well documented. It’s therefore quite easy to use ready-made products, such as mobile-first solutions, or outsource particular services to other companies.

Scenarios where you can consider going for microservices

Monolithic application migration due to improvements needed in scalability, manageability, agility or speed of delivery.

Re-platform a legacy application by transforming functions/modules to microservices.

Rewriting legacy application to modern languages, technology stack to meet the demands of modern business.

Individual cross-cutting services that are independent in nature. For example encryption services, authentication services, etc.

Independent business applications or services reused across multiple channels. For example, payment services, login services, flight search services, customer profile services, notification services, etc.

Commonly used enterprise applications. For example, time tracking application.

Scenarios where a service provider makes computing resources and infrastructure management available to the customer as needed. For example, forecasting services, price calculation services, prediction services, etc.

Back-end services for responsive client-side web application where data could be coming from multiple channels or different data sources.

Highly agile applications or applications demanding speed of delivery or time to market or innovation pilots. Applications that got polyglot, multi-language, cloud application development.
