CDN 3.0?

... easier to manage is to use Openshift 3.0
as the infrastructure of the CDN.

CDN topology

Scattered CDN

Consolidated CDN

physical proximity minimizes latency
effective in low-connectivity regions
smaller POPs are easier to deploy

Higher maintenance costs
RTT prolonged by multiple connection points
Cumbersome to deploy new configurations

High-capacity servers are better for DDoS mitigation
Enables agile configuration deployment
Lower maintenance costs

Less effective in low-connectivity regions
High-capacity POPs harder to deploy

CDNW CS

CDNW NGP

vs.?

CS와 NGP가 계속 따로 운영될 수 밖에 없는 구조.

통합은 어렵다. 새로 만드는게 더 빠르다 --> PJ WE?

일부라도 좀 더 고쳐 보자. MSA로 변경해 보자 --> 통합은 여전히?

더 큰 그림(architecture)가 필요하다. 하지만 누가?

컨테이너화의 대상은? docker는 기술일 뿐? 우리에게 맞추려면?

CAPEX & OPEX를 줄이기 위해서 SD(Software-Defined)를 적극적으로 적용?

Ganglion model

or Nerve knot model

Scattered Cache network on regional consolidated data processing hubs

with Central Cloud system

Ganglion Model

Scattered CDN

Consolidated CDN

Ganglion(or Nerver Knot) Model

Ganglion(or Nerve Knot) - Consolidated. Regional. High-Powered. Calculated.Sub-processing. = Real Time, Fast Data, RUM, Log Gathering&Processing, Cloud Storage, dynamic routing

Edge/Node/PADs - Scattered. Throughput. Cached. Consumed. = front & surrogated cache, local storage,

Central Cloud - hyper-Consolidated. Central. Super-High-Powered. Calculated.All-processing = Batch, Big Data, Log Delivery, Billing/Stat/Report, Database, Backup, Contingency plan with Ganglion

Code Deployment - Quality Control system
