Speedycloud-Cloud Computing Journey

Thank the old boy teacher for giving us a tour of cloud computing (Schindler Yuncheng) and Dong to explain the cloud computing opportunities for us.

Here are the points of knowledge I've learned:

The 5 major features of ① cloud computing (Cloud Computing):

1, measured service measurable services

# Cloud systems use metering methods to automate and optimize resource usage for service types. (for example, storage, processing, bandwidth, and number of active users). The use of resources can be monitored, controlled, and transparent to suppliers and users (i.e., pay-as-you-use models).

# The cloud software is fully Cloud Computing Paradigm Advantage to service oriented, focusing on stateless, loosely coupled, modular, and semantic interpretation capabilities.

2, Rapid elasticity rapid expansion

#一种对资源快速和弹性提供和同样对资源快速和弹性释放的能力. For consumers, this ability is unlimited (on-demand, large-scale computer resources) and can be purchased at any time and in any quantified manner.

3, Resource Pooling resource pooling

# dynamically dividing or releasing different physical and virtual resources according to consumer needs, these pooled vendor computing resources provide services in a multi-tenancy model. Users often do not control or understand the exact partitioning of these resource pools, but they can be aware of the resource pools in that administrative area or data center. Examples include storage, compute processing, memory, network bandwidth, and number of virtual machines.

4. Broad Network access Everywhere

#借助于不同的客户端来通过标准的应用对网络访问的可用能力.

5, On-demand self-service with the need for self-service

#消费者无需同服务提供商交互就可以自动地得到自助的计算资源能力, such as server time, network Storage (self-service for resources).

② Cloud Computing Service model

IaaS (OPS personnel)

Paradigm Shift: Infrastructure as an asset

Features: usually independent of the platform; Infrastructure costs are shared to reduce; SLAs; pay by usage; self-scaling

Keywords: Grid Computing, utility computing, compute instances, hypervisor, cloud bursting, multitenant computing, resource sharing

Advantages: Avoid capital investment in hardware and human resources, reduced ROI risk, low entry threshold, simplified and automated scaling

Weaknesses and risks: business efficiency and productivity rely heavily on supplier capacity; long-term costs may be higher; centralization requires new/different

Security

Not applicable time: When capital budget is greater than operating budget

PaaS (Developer)

Paradigm Shift: Licensing procurement

Features: Using cloud infrastructure, service Agile Project management approach

Keywords: solution stack

Advantage: Simplified Version deployment

Weaknesses and risks: centralization requires new/different security measures

Not applicable time: N/A

SaaS (end-user)

Paradigm Shift: Software as an asset (Enterprise and consumer)

Features: SLA, thin client application driven UI, cloud component, communication via API, stateless, loose coupling, modularity, semantic interoperability

Keywords: thin client; client-server application

Advantage: Avoid capital investment in software and development resources, reduce ROI risk, simplify and iterate updates

Weaknesses and risks: centralization requires new/different security measures

Not applicable time: N/A

③ Cloud Computing Deployment model

1. Private Cloud:

An enterprise or other organization is set up in its own data center, or by a cloud service provider such as a business online, and then leased to the user as a whole. Users other than the owner are not available;

2. Community Cloud:

"Community Cloud" is an integral part of the big "public cloud" category. Refers to the cloud computing form of computing resources, network resources, software and service capabilities provided by cloud computing service providers within a certain geographic area. That is, based on the characteristics of network interconnection advantage and easy integration in the community, through the integration of various computing capabilities in the region, combined with the common needs of users in the community, the cloud computing service model is realized for the demand of regional users.

3. Public Cloud:

The public cloud is to put the set of cloud resource pool on the Internet, all users who have access to use can be used on demand;

4. Hybrid Cloud:

Refers to the mix of public and private clouds, most of which refers to the need to use public clouds as a supplement to the private cloud when the private cloud is built and, for reasons of business development, exceeds the resource pool.

The following Dong also talk about virtualization technology introduction, cloud knowledge structure, Speedycloud Cloud Platform Introduction, cloud Platform building rules, Speedycloud Cloud Platform,speedycloud open platform, build their own PAAs platform. It's not so much to understand.
