INTRODUCTION OF
MICROSERVICES

MICROSERVICES
Microservices is a software architecture style, in which
complex applications are composed of small,
independent processes communicating with each
other using language-agnostic APIs.

3 LEVELS OF MICROSERIVCES
Task
Service
Container
Executed only one time like a command
Live longer than task like a daemon
An instance of a machine image
E.g. Actor, Microsoft Service Fabric
E.g. Service / Microsoft Service Fabric
E.g. Docker container

MICROSERVICES
Pros
▪ Small and Simple Application
▪ Scalable
▪ Fault tolerance
▪ Isolation
▪ Multi frameworks
Cons
▪ Complexity of developing a
distributed system
▪ Multiple database
▪ Transaction management
▪ Debug / Test
▪ Deploy and operation

15.
WHEN TO USE
Scalable Service

16.
MICROSERVICES PLATFORMS
Mesosphere DCOS & Microsoft Service Fabric
Learn by examples

17.
WHY MICROSERVICE PLATFORMS ARE IMPORTANT?
Conquer the short comings
Developing
a distributed system
Deploy and Operation
Debug and Test Mesosphere DCOS Microsoft Service Fabric
It makes incredibly easy to develop microservices.

18.
MESOSPHERE DCOS
A new kind of operating system that spans all of the
servers in a physical or cloud-based datacenter, and
runs on top of any Linux distribution.
You can operate cluster as if you use
an os of single machine.

19.
DATACENTER OS
Datacenter OS make us possible to operate cluster like
an Operation system.

0.5 cpus and 512 mem, please
slave 2: Hi, I have one. I allocate it.
master: Great, lets do it.
