This paper takes cloud computing as an example to analyze the core technology of cloud computing and the learning focus of cloud computing. I believe you have a certain understanding of the core technology of cloud computing after reading the complete article.

Cloud computing is an Internet-based computing method, to achieve cloud computing requires a set of technical architecture to implement, including network, server, storage, virtualization and so on. Cloud computing is currently divided into public cloud and private cloud. The difference between the two is that the objects of the services provided are different, one is for internal use, the other is for the public. At present, private clouds in enterprises are achieved through virtualization, it is recommended that you can understand the prospects and development of the virtualization industry.

Virtualization is currently divided into server virtualization (represented by VMware), desktop virtualization (Citrix has a greater advantage than vmware), and application virtualization (represented by Citrix). Learn the basics of virtualization:

Operating system, understand the installation and basic operation of Windows operating system (Windows Server 2008, Windows Server 2003, Windows 7, Windows XP), understand the installation and management of AD domain roles, understand the configuration and management of group policy

Installation and use of databases (SQL Server)

Basic knowledge of storage (disk performance, RAID, IOPS, file system, FC SAN, iSCSI, NAS, etc.), use of fibre switches, use of Open-E to manage storage

4. Basic knowledge of the network (IP address planning, VLAN, Trunk, STP, Etherchannel)

All computer beginners are the same: computer network, operating system principle, computer composition principle, database principle, data structure, these doors first take a good look, slowly ponder, first have a perceptual understanding and then slowly deepen.

What operators need to learn can be divided into four stages:

1. Fundamentals, Linux foundation and network foundation, including the use of basic commands, basic structure principles of Linux system, system management, disk management, raid array, common faults, monitoring and tuning of system performance, network aspects not only learn the basic principles of network, but also go deep into tcp/ip http and so on.

2. In-depth, the construction and configuration of basic services, such as Apache,nginx,bind,DHCP FTP, etc., and shell scripts must be learned, and you must learn Python if you have the ability

3. Advanced, some cluster construction, load balancing, high availability, database, common automatic operation and maintenance tools and the use of monitoring, etc., cluster high availability such as lvs,keepalived,heartbeat,brdb,memcached, then MySQL database must be able, common MySQL cluster and so on, automatic operation and maintenance workers have: puppet,ansible,saltstack, monitoring tools are: zabbix,nagios.

4. Advanced, that is, virtualization technologies, such as VMware,xvm,xen, and the current very popular docker can try.

If you can read this, congratulations, you already have the most profound theoretical understanding of what are the core technologies of cloud computing. If you want to read more related articles, you are welcome to follow the industry information channel!
