Getting Started with Cloud Computing Tutorials

With the popularity of cloud computing, more and more websites and applications on IDC are starting to go to the cloud. At the same time, for us IT practitioners, we are also facing the challenge of speeding up learning cloud computing and not being eliminated by new technologies. So let ’s talk about how to learn cloud computing faster!

1. Learning ideas
a) It is recommended to understand before studying

i. What is cloud computing
ii. What impact does cloud computing have on the current business model
iii. Technology involved in cloud computing
iv. Status of cloud computing
b) Cloud computing can be divided into broad and narrow categories

Cloud computing in a narrow sense refers to the delivery and usage model of IT infrastructure. Refers to obtaining the required resources through network requirements and expansion methods; broadly, cloud computing refers to the use and delivery mode of services, and refers to obtaining corresponding services through the network according to demand and expansion methods. This service can be IT, but it can be software, it can be the Internet, or any other service. It has unique functions such as ultra-large scale, virtualization, reliability and security. Cloud computing has the following characteristics:

i. With a very large scale, the general enterprise private cloud is hundreds of thousands of servers, and some even millions of servers.
ii. Virtualization, users can use any terminal to obtain application services at any time.
iii. High reliability, the cloud applies multiple copies of data fault tolerance, and the calculation nodes are homogeneous and interchangeable.
iv. Universality, that is, the same cloud can support different applications.
v. High scalability, the cloud scale can be dynamically scaled to meet the growth of application and user needs.
vi. On-demand services. Cloud resources are huge and can be purchased on demand. It is a bit like "communism." On-demand distribution. Ha ha
vii. Its cheap, "cloud" special fault tolerance measures. The versatility of "cloud" greatly improves the utilization rate of resources compared with traditional systems, making it more "affordable" to use.

2. Application platform

a) Popular cloud computing platforms (with free trial), take a look at what services are included in cloud computing. Like cloud computing, cloud storage, cloud parsing, etc.

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 platform (Iaas, Paas): You can study virtualization technologies (kvm, hyper-v, etc.), OpenStack, esxi and other Iaas technologies. paas aspect
