Microservice Architecture platform

Microservice
is a collection of small, independent, loosely coupled, and autonomous
services. Here each service is self-contained and implements a single business
capability. Its services can be deployed independently and can be updated on
the existing service without re-building and re-deploying the entire
application. The services in this architecture are responsible for persisting
their data or external state. This approach is very different from the
traditional model where there is a separate layer that handles the
persistence. Here services communicate
with each other by using the well-defined API in the model. Here internal
implementation details are hidden from the external users and they have
displayed the necessary information required by them. Most importantly services
are not required to share the same technologies such as technology stack,
libraries, or framework. In this architecture, each component is responsible
for placing the services on the nodes, identifying the failures, rebalancing
the services across the platform. Along with this it also provides the facility
of API gateways which help in forwarding the call to the appropriate services
on the backend. With the help of this facility, it decouples the clients from
the services. The services can be versioned and refactored without updating all
clients. Further thus platform also supports the messaging protocols. Further,
this architecture also supports authentication, logging, SSL termination, and
load balancing.
Benefits
of micro-service architecture
- Microservices are deployed independently which
supports agility.
- The services can be versioned and refactored
without updating all clients.
- It supports the small and dedicated teams to
process the services that support testing, updating, and maintaining the
functions in well-versed form.
- It has a small code base that provides the
facility of updating the services more effortlessly.
- It also provides the facility to its uses to
select technology from various technologies provided in the platform or
can use the combination of various technologies as per requirement.
- Further, it also provides the facility of fault
isolation as a single bug will not affect the entire application.
- Its services can be scaled independently
without scaling the subsystems.
- It provides an easier method of performing the
schema update.
- This architecture is highly maintainable and
is loosely coupled. It is independently deployable.
DevOPs
and its application in Microservices
DevOps are a
set of practices that combines software development and IT practices under one
umbrella. The main objective of DevOps is to reduce the software development
life cycle and provide continuous and high-quality service to its users. DevOps
helps in breaking the wall between the operations and development for creating
the rapid and automated process that helps in faster development of the
applications. Here both the operation engineers and development engineers are
jointly involved in the software development. The microservice architecture
builds the complex architecture from its microservices and by using the DevOps
the development of these services can be done in a better way. It helps in
breaking down the complex processes in a smaller form and then performing the
task of development. It helps in increasing the productivity and reliability of
the services provided through this architecture. It further supports in
creating the services on various servers in an easier way. Most importantly it
supports the round-to-clock mode of service availability to its users. It
provides improved agility that allows for quick results, rapid reiteration, and
quicker time for deployment. As these services are loosely coupled the
management of the entire application is easier. The management of the service
is easier in comparison to other approaches. By implementing the DevOps in the
microservices the application deployment and development becomes less
time-consuming. It also supports fault tolerance and bug removal from the
application. Here the deployment, testing, collaboration, and maintenance of
the application can be done more easily. Along with this it also provides the
facility of API gateways which help in forwarding the call to the appropriate
services on the backend. With the help of this facility, it decouples the
clients from the services. The services can be versioned and refactored without
updating all clients.
