Microservices are an architectural and organizational approach to
software development where software is composed of small,
independent services that communicate over well-defined APIs.
These services are owned by a small, self-contained team.
Microservices architectures make applications simpler to scale
and faster to develop, enabling innovation and accelerating time-
to-market for new features

What tool we are using to deploy microservices for GIS Application?
3. Introduction What are microservices? Microservices are an architectural and organizational approach to software development where software is composed of small, independent services that communicate over well-defined APIs. These services are owned by a small, self-contained team. Microservices architectures make applications simpler to scale and faster to develop, enabling innovation and accelerating time- to-market for new features.
4. Introduction What are microservices? With a Microservices architecture, an application is built as independent components that run each application process as a service. These services communicate via an interface using lightweight APIs. Services are built for business capabilities and each service performs a single function. Because they are independently run, each service can be updated, deployed, and scaled
5. Flexible Scaling Allow each service to be independently scaled up/down Easy Deployment Making it easy to try out new source code and roll back if something doesn’t work. Technological Freedom Teams have the freedom to choose the best tool for each job. Reusable Code A service written for a certain function can be used as a building block for another feature. Resilience Service independence increases an application’s resistance to failure. Introduction Benefits of Microservices Agility Microservices foster an organization of small, independent teams that take ownership of their services, shortening development cycle times.
6. Old-way GIS applications The old way of designing and deploying GIS applications was based on a monolithic architecture, which could not scale service components and had the risk of making the entire application non- functional if any components failed.
7. Old-way GIS applications
8. The new GIS application is designed and deployed on base of micro services architecture, which separates services into small components. These services communication via a well-defined APIs, Protocol and each component can be scaled to accommodate usage, That new way following the Twelve-Factor APP. (https:// 12factor.net) New-way GIS applications
9. The Twelve Factor 1 2 3 4 5 6 One codebase tracked in revision control, Many deploys Codebase Explicitly declare and isolate dependencies Dependencies Store config in the environment Config Treat backing services as attached resources Backing services Strictly separate build and run stages Build, release, run Execute the app as one or more stateless processes Processes
10. The Twelve Factor 7 8 9 10 11 12 Export services via port binding Port binding Scale out via the process model Concurrency Maximize robustness with fast startup and graceful shutdown Disposability Keep development, staging, and production as similar as possible Dev/prod parity Treat log as event streams Log Run admin/management tasks as one-off processes Admin processes
