AGENDA
Is Monolith a real problem?
Why Micro-Services?
How we gonna do Micro-Services?
Why Service Fabric?
What is Another Way?
IS MONOLITHA REAL PROBLEM?
MONOLITH
Azure
AWS
Desktop
Browsers
80% backend logic 20% backend logic
Monolith
MONOLITH - SCALABILITY

MonolithInstance 1
MonolithInstance 2
MonolithInstance 3
MonolithInstance N
Stateless & Scalable
Redis
SQL – limited scale –
10% load
PROBLEM - TECHNICAL
1 Language / Platform limitation
Module cannot be scaled separately
DB Schema sharing
PROBLEM - BUSINESS
Acquiring several companies
Expecting growth ~ x5 in a year
Targeting for Hybrid solution
WHY MICRO-SERVICES?
SCALING & HARDWARE
~ 20 Modules
3 – High Load
1 – requires Memory
GPUModule 1
GPUModule 2
SSDModule 1
SSDModule 2
Node with SSDNode with GPU
LANGUAGE & TOOLS
Use appropriate language & tools for component goals
Languages:
Java
.NET
NodeJS
Ruby
C++
Python
Storages & tools:SqlServer
MySql
Redis
ELK
Kafka
Apache Solr
Apache Spark
HYBRID (CLOUD + ON PREMISES)

HOW WE GONNA DO MICRO-SERVICES?
REQUIREMENTS - SYSOPS
Infrastructure
Platforms
Scalability
Hardware
REQUIREMENTS - DEVOPS
Script minimization
Upgrade in single command
High Availability & Self-Healing
Service Discovery
Hardware Constraints
DEPLOYMENT – SERVICE PER VM
DEPLOYMENT - CONTAINERS

WHY WE CHOSESERVICE FABRIC?
WHAT IS
Service Orchestrating Tool
SERVICE FABRIC vs CONTAINERS ORCHESTRATION
Service Fabric Containers
Orchestrating Services Containers
Ops Cost Low Medium
App Infrastructure One SDK Custom
Scaling Instance + Partitioning Instance
Service Isolation No, Container, Kernel Container
