Cloud computing is an Internet-based computing method, and to achieve cloud computing requires a complete set of technical architectures to implement, including networks, servers, storage, virtualization, and so on. Cloud computing is currently divided into public and private clouds. The only difference between the two is the object of the service provided, one is for internal use by the enterprise, and the other is for the public. At present, private clouds in enterprises are realized through virtualization. It is recommended that you can understand the prospects and development of 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 needs:

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

Database installation and usage (SQL Server)

Basics of storage (disk performance, RAID, IOPS, file system, FC SAN, iSCSI, NAS, etc.), use of Fibre Switch, managing storage with Open-E

4. Network fundamentals (IP address planning, VLAN, Trunk, STP, Etherchannel)

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

The training can be divided into four stages:

1. Foundation, Linux foundation and network foundation, including the use of basic commands, the basic structure principle of Linux system, system management, disk management, raid array, common fault pats, system performance monitoring and tuning, network aspects In addition to learning the basic principles of the network, we must go deep into tcp/ip http, etc.;

2, in-depth, basic service building and configuration, such as Apache, nginx, bind, DHCP FTP, etc., there are shell scripts must be able to, have the ability to learn Python;

3. Advanced, some cluster building, Load Balancer, high availability, database, common automatic operation and maintenance tools and monitoring use, cluster high availability such as lvs,keepalived,heartbeat,brdb,memcached, then MySQL database must know, common MySQL cluster and so on, automatic operation and maintenance tools include: puppet,ansible,saltstack, monitoring tools include: zabbix,nagios.

Advanced, that is, virtualization technologies, such as VMware,xvm,xen, and docker, which is currently very popular, can be tried.

As for learning, it is strongly recommended to read these books first: computer networks, operating system principles, computer composition principles, database principles. In this case, to the end of a lot of concepts are not clear and then fall into it, the world is always the same. Then build Linux system with VMware or virtualbox on win platform, start with the most basic Linux knowledge, you can also find online video tutorials. Learn the basics in a solid manner and slowly learn advanced content. Finally, it is strongly recommended that operation and maintenance who cannot program is not a good program ape. You must learn shell programming well, learn Python, and know some data structure block content.
