云的服务层次和
类型
公共云私有云混合云
（提供商－互联网）（数据中心－内部网）（公共和私有）

提供的是 “服务”

应用、流程和信息作为服务（ SaaS ）
（行业应用， CRM ， ERP ， OA 等）

平台作为服务（ PaaS ）
（优化的中间件－应用服务器，数据库服务器等）

基础架构作为服务（ IaaS ）
（虚拟的服务器、存储和网络）

Amazon Web Services (IaaS)

 EC2 (Elastic Compute Cloud)
 S3, simple storage service (PaaS)
 SDB, simple database based on
MySQL
 SQS, simple queue server
 Virtualization Only, w/o
Provisioning & Lifecycle Mgmt



AWS Commercial Case
 EC2- elastic

Open Cloud Manifesto (cont'd)

 What is Cloud & Why important?
– Scalability on Demand
– Streamlining the Data Center
– Improve Business Processes
– Minimize Startup Costs
 Challenges & Barriers to Adoption
– Security
– Data & Application Interoperability & Portability
– Governance & Management
– Metering & Monitoring



Open Cloud Manifesto

 The Goal of an Open Cloud
– Choice
– Flexibility
– Speed & Agility
– Skills
 Principles of an Open Cloud
– Open collaboration
– Not to lock into particular
platforms
– Existing standards
– Driven by customer needs



Apache Hadoop (Open Source)
 Map Reduce  HBase



Apache Hadoop Algorithm



Security Consideration (I)

 Certification and accreditation
Sarbanes Oxley (SOX) Compliance -
Audit standard / Service Organziation
 Restricted physical security
 Redundant backup
 Virtual instance w/ stateful firewall &
signed API call
 Host vs Guest
 SSH, Firewall by IP, port 80, 443, 50000
 API through X509


Security Consideration (II)

 The Hypervisor
 Isolated instance
 Network security
 DDoS
 Man in the middle
 IP Spoofing
 Port scanning
Packet filtering
 Data management


Grid versus Cloud Computing

 Cloud = Services, On-demand and Service Oriented
 Cloud users don't own infrastructure. They rent it.
 Cloud evolved from Grid, but provides application- delivery
transparency!
 Grid = High Performance Infrastructure for a specific
purpose
