With the popularity of cloud computing, more and more websites and applications on IDC begin to go to the cloud. At the same time, for us IT practitioners, we are also faced with the challenge of speeding up learning cloud computing and not being eliminated by new technologies. Where should I start if I want to learn cloud computing? Let's take a look.

1. Learning ideas

A) it is recommended to understand before learning

i. What is Cloud Computing

ii. What is the impact of cloud computing on current business models

iii. The technology involved in cloud computing iv. The status quo of Cloud Computing

B) Cloud computing can be divided into two categories: broad and narrow

In a narrow sense, cloud computing refers to the delivery and usage model of IT infrastructure. It refers to obtaining the required resources through the network demand and expansion; in a broad sense, cloud computing refers to the service use and delivery model, which refers to the corresponding services obtained through the network in the way of demand and expansion. This service can be IT, but software, can make the Internet phase, can also be any other service, it has a large scale, virtualization, reliable security and other unique functions. Cloud computing has the following characteristics:

i. With a very large scale, the general enterprise private cloud is hundreds of servers, some even millions of servers.

ii. Virtualization, users can use any terminal to obtain application services at any time.

iii. With high reliability, cloud uses measures such as fault tolerance of multiple copies of data, isomorphism and interchangeability of computing nodes.

iv. Versatility, that is, the same cloud can support different applications to run.

v. Highly scalable, the cloud scale can be dynamically scaled to meet the growing needs of applications and users.

vi. On-demand services, the cloud has huge resources and can be purchased on demand.

vii. Extremely cheap, the special fault-tolerant measures of "cloud". The versatility of "cloud" makes the utilization of resources greatly higher than that of traditional systems, making it more "affordable" to use.

2. Application platform

A) popular cloud computing platform (free trial) to see what services cloud computing includes. Such as cloud computing, cloud storage, cloud resolution and so on.

3. Learning content of different positions

A) for learning, I think it can be divided into two directions:

i. Big data, nosql field: Hadoop, Hbase, Cassandra and some theories (CAP, Base, etc.)

ii. Cloud platforms (Iaas, Paas): you can study virtualization technologies (kvm, hyper-v, etc.), OpenStack, esxi and other Iaas technologies. You can study cloudfoudry on the paas side.

The above is a brief introduction to where cloud computing should start. Of course, you have to use the above differences in detail before you understand it. If you want to know more, welcome to follow the industry information channel!
