"The Cloud Revolution" reading notes

Here are a few points to note:

Chapter One: The Cloud Revolution

(1) Higher maintenance efficiency and lower cost

(2) Faster data search

(3) Develop a lot of new software, Hadoop

(4) Peer computing: before (PC and server belong to servant relationship) Now (end user can request computing power from cloud server)

(5) Amazon is the leader in cloud computing, EC2

(6) Eidetics Company's drug search function from Oracle to EC2, saving a lot of time.

The Internet server cluster is not the most important feature of the cloud, the most important feature of the cloud is the realization of the peer relationship between the end user and the server, which is the defining characteristic of the cloud, which has the greatest impact on the enterprise.

Chapter II: Variable shape, elastic cloud

(1) The Cloud Data center, which has a plurality of 7-foot racks, looks very specific, but the user's cloud machine will expand with the user's needs, the processing peak is over, the cloud machine will shrink, one will be on the side of the data center, one will be on that side, unpredictable. At this point, cloud elasticity is very important

(2) Sony transferred the Internet music service to EC2.

(3) Cloud monitoring service

(4) Amazon EC2, runs a Linux server, charges 8.5 cents per hour, runs a Windows server and charges 12 cents an hour; in Rackspace Cloud, run a Linux server and charge 1.5 cents per hour. Small businesses benefit.

(5) Cloud is a business model

(6) Most use X86 chip, also useful other.

(7) Cloud market Youdao high threshold, Hadoop cloud software (data analysis System).

(8) Backup battery, software fault tolerance

Chapter III: Virtualization, changing everything

(1) achieve "bigger than the actual" effect.

(2) The cloud is able to achieve economies of scale, flexible operation, end-user remote and smooth access, not only because of the use of PC components to build large data centers, the use of Network service standards or to automatically balance the load, but mainly because of virtualization.

(3) Cloud definitions do not require servers in the cloud datacenter to be virtualized. However, in the long run, without virtualization, there is no competitive advantage for the public, multi-tenant cloud.

(4) at the end of 09, VMware replies: One core can support 16 end users

(5) Removable payload package: Virtual Appliance Traditionally, the operating system is dealing with hardware, and it is now a conversation with applications that transfer the needs of applications to super supervisors.

The fourth chapter: the Private Cloud, the first clue

(1) For safety reasons

(2) Hardware selection of private cloud, Dell; Cisco is a major supplier of nebulae; Hewlett-Packard and IBM have similar plans

Fifth: The ultimate goal: hybrid cloud

Sixth: Overcoming resistance and introducing cloud

(1) The user cloud standard of the forces DMTF

The seventh chapter: it reorganization

The eighth chapter: Hidden Dangers: Cloud security

The Nineth chapter: your cloud strategy: what kind of business do you want

The tenth chapter: Planning for the future
