Global Platform Layers

Infrastructure Layer

Software Layer

Let’s talk about Global Platform Characteris-tics from Infrastructure to Software Layer

(Full Stack) !!

INFRASTRUCTURE LAYERPART I.

Stack

Infrastructure Stack

Data Center

Server

Cloud OS

Storage

[I. Infrastructure Layer]

Location• Regulation• Bandwidth• Climate (Cooling)• Recruitment• Operation (24x7, Follow The Sun)

PUE Global Center vs Regional Cen-

ter Zone

Data Center

컨테이너 기반 4 세대 데이타 센터


Commodity Server• Cost• Density

POD• Standard Design• Scale Out Unit [Procurement]

Network• Management Line• Service Line• VM Movement Line• SAN (iSCSI)

Resiliency vs Redun-dancy

Server

Google Server Design

Microsoft Server Design

Facebook Server Design


IO Segregation

Storage [I. Infrastructure Layer]

Open Source vs Commercial• Open Source is not so cheap

And DevOps

Cloud OS

[ Development Cost , Server H/W Cost, SW License Cost, Mainte-nance Fee]

※ Open Source : Open Stack Nova Level Approach


Use first for Time to Market !! Build later after learning

Use or Build? [I. Infrastructure Layer]

SOFTWARE LAYERPART II.

Software Stack [ II. Software Layer ]

Data Storage

Business Logic

Proxy Identity Management

Identity Management• Authentication & Authorization and Profile Management• IM (Master Data), AM (Authentication Only/LDAP),PM (Provision-

ing)• Integrate with Legacy System (Telco)• Global Replication across Data Center• Regulation

Proxy• Similar to SOA Enterprise Service Bus• Routing• Message Transformation (※ HTTP Header change)

• Throttling• Logging+ External or Internal Interface (like Enterprise Application Integration)

Protocol• REST, Thrift, Protocol Buffer

IDM and PROXY [ II. Software Layer ]

Biz Logic• No shared data, Stateless

Prevent Trouble Propagation, Provides Scalability

• Think about productivity Python, Erlang

Business Logic [ II. Software Layer ]

Data - Storage• File Storage – COST and Consistency, Availibility• Simple Data Storage - NoSQL Combination• Relational Data Storage – RDBMS with Sharding , Query Off Load-

ing• Small & High Performance Data Storage – In Memory Data Grid

Data Implementation Technology• Big Data Processing - Map & Reduce• Data Replication (across data center) – ETL, CDC and Filtering
