New Section
VNG Corp introduction

VNG Corporation
• Game publisher/developer (VLTK, VLCM,
Gunny, Boom, Khu vuon tren may,
ZingPlay …)
• Online music/media (ZingMP3, ZingTV)
• Social network (Zing Me, Zalo)
• E-commerce (123mua.vn, 123pay.vn)

IRD Department
Research and build the infrastructure platform for
VNG to enhance business, optimize quality and cost,
meet the new technology.
• Content Delivery Network (CDN) system is used
by all VNG products that want to optimize static
bandwidth.
• Live-streaming system is a streaming platform for
Zing events, Talk TV.
• OpenStack provides servers and networks for
some products with a small scale (in pilot phase.
Project Team is receiving feedback for further
enhancement).
• Object storage (in POC phase).

What is Cloud computing?

Cloud Services

Cloud Services
• AWS #1 of cloud services provider - What services
AWS provide?
– Amazon Web Services (AWS) continues to dominate
the IaaS and PaaS space in terms of revenue. AWS:
3.8$B revenue (2013)
– Compute & Networking (Amazon EC2, Auto Scaling,
Elastic Load Balancing, Route 53 ,..)
– Storage & CDN (Amazon S3, Amazon Glacier a low
cost storage for backup, Amazon EBS, Cloud
Front/CDN)
– DB – Cache: RDS (MySQL, Oracle, SQL Server, and
PostgreSQL), DynamoDB (NoSQL data store),
ElastiCache (In-Memory Caching Service), Redshift
(Data Warehouse Service)
– Application services: Elastic Transcoder,..

Cloud Orchestration Framework

New Section
OpenStack Architecture

History
• OpenStack is an open source IaaS
initiative for managing and creating huge
groups of virtual private servers in a cloud
computing environment. It was initially
developed by Rackspace and NASA.

Nowadays

Servers Storage
Network switch Network switch Network switch
Virtualization Solution (VMWare VCenter,
Citrix XEN Server, Ovirt, Proxmox….)
Hypervisor (VMWARE, XEN, QEMU, KVM, Hyper-V)

Cloud Infrastructure
• Modular architecture
• Designed to easily scale out
• Based on set of core services

Infrastructure As A Service Overview

Infrastructure As A Service roles
• Cloud Ops: monitor/add/remove physical
compute nodes, storage nodes, controller
nodes, network nodes.
• App Owner: add/remove/upgrade cloud
services, check billing status.
• Dev Ops: launch/ terminate/ scale instances,
storage. Register/ unregister new image.
Backup/ restore instances/ storage. These
tasks can be done via dashboard or API.
• App Devs: call the dev ops tasks inside
application logical flow.

Ceilometer

Monitoring
• Monitor physical host by cacti, graphite,
zabbix.
• Monitor instances status by ceilometer.
• Monitor OpenStack statistics by
ceilometer.

Ceilometer
• Objectives
• Ceilometer component
• Ceilometer collect data
• Access collected data

Objectives
• Provide a infrastructure to collect
any information in OPS.
• Publish information for other
monitoring.
• Integrate with Heat for trigger auto
scale.
Celiometer - OpenStack - VNG - IRD

Ceilometer collect data
• Bus listener
• Polling agent
• Push agents

Ceilometer

Process meter

Access collected data
• Via API
• Via Ceilometer command
