Let's see what is Agile Manifesto in its original form, and that can make us realize how microservices has to eventually hatch up.

Agile software development also meant to bring back software development control to the developer community from the project management and quality standards communities. The Agile Manifesto includes the following guidelines:

• Individuals and interactions over processes and tools
• Working software over comprehensive documentation
• Customer collaboration over contract negotiation
• Responding to change over following a plan

These are clear motivations reflected here, and are also the differentiating points for SOA-enterprise-standards-based architecture's transition to microservices architecture.

Agile Manifesto is based on twelve principles. For example, one of the principles is Continuous attention to technical excellence and good design enhances agility. Since these are pretty generic development motivational principles, we leave them to the source. Please visit http://agilemanifesto.org to see all of the principles.
