Application Architecture

We’ll help you select the architecture that will best supports the needs of your
application as you imagine it today and for future development:

Multitier architecture

When it comes to application development, we focus on maintaining as much architectural simplicity as is possible while considering your future needs. Typically, we suggest a traditional architecture for mid-sized applications to ensure their fast development, easy testing, and simplicity of maintenance.

Microservices Architecture

  • Microservices-based application – our use of microservices can help build your projects faster, have a less complex system, and allow for quick repairs, continuous deployment, partial updates, and upgrades with limited to no downtime of your system.
  • Adding new components to an existing microservices infrastructure -have the ability to quickly implement and add new functionality to an existing infrastructure as newly arising business needs, rather than creating an entirely new program.
  • Monolith application refactoring – we split your current application into smaller and simpler pieces that function independently in order to prevent it turning into a monolithic program this is slow and difficult to maintain as it continues to develop.

Cloud-native architecture

We can build your application tailored to cloud services to deliver a modern advanced app with maximal scalability and availability that benefits from significantly reduced operational costs.
