Notes to entry: do I need to know programming for O & M?

First , It's safe to say , In the future IT The post needs people with strong comprehensive ability , Operation and maintenance 、 Development 、 database 、 The Internet , Technical posts should have some knowledge of the above knowledge systems , To be well qualified for the corresponding post .

The following is no longer a trend , It is something that both novices and old birds must seriously consider ：

• 1、 The operation and maintenance personnel shall be able to operate and maintain 、 Development 、 database 、 The Internet , But the focus is on operation and maintenance ,

• 2、 Developers should be able to operate and maintain 、 Development 、 database 、 The Internet , But the focus is on development ,

• 3、 Database personnel should be able to operate and maintain , Development , database , The Internet , But the focus is on databases ,

• 4、 Network personnel should be able to operate and maintain , Development , database , The Internet , But the focus is on the Internet , It is better to focus on operation and maintenance ,

• 5、 Hardware Engineer （F5, Storage devices, etc ） It is suggested to transfer as soon as possible Linux Operation and maintenance , Cloud computing has wiped out hardware , The hardware is centralized .

Technical knowledge is not enough , working attitude , Quality of life , Communicate and express , The sense of responsibility is the capital that is easy to be ignored with core competitiveness ！

The proportion of technical knowledge and attitude quality is close to 6:4, The higher the position, the lower the proportion of technical requirements ！

Internet , Mobile Internet , Even in the age of the Internet of things IT The demand for comprehensive ability of talents is higher and higher ！ Some very low-end jobs, most people's jobs will be automated 、 virtualization 、 Cloud computing 、 Even robot replacement is no exaggeration ！

for example ：IDC Machine room operation and maintenance , Low end network engineer , Various hardware engineers .

How far can operation and maintenance personnel who do not know programming go ？

The new era is for us IT People have new challenges , We cannot cling to the incomplete , And we must learn quickly , Adapt to the more requirements of the times , Don't be selfish , Simply think that O & M does not need development , Development does not require operation and maintenance , These ideas are repeating the fable of stealing the bell from the ear .

in addition , Strongly recommended , Want to engage in Linux The operation and maintenance friends must first master the skills required by the good luck maintenance post , And then encroach on the development field . If you want to engage in development, you must first master the skills required by the development position , And then nibble at areas such as operation and maintenance .

Bear in mind , Don't be too impetuous , parrot , Do not play Linux, Side play development , Focus on one thing at a time , You can find a job faster , After you find a job, you can use the weekend to train or self-study , Unless you attend a full-time training class , Or time is really abundant .

After mastering the knowledge and ability of a post , If you really master it , It will be much easier to learn other post skills , Because the methods of learning are interlinked .

Be sure to master the basic skills of the position in this field you want to engage in , Don't know everything in a short time , It will make everything loose , Finally, I ran into a wall when I was looking for a job , In a short time, we should focus on the key points .

Although the demand of enterprises for operation and maintenance positions is getting higher and higher , But it doesn't mean that you can't find a job just by learning .

For novice , It is impossible to master the skills of operation and maintenance and development in a short time , Even the operation and maintenance knowledge is massive , Learn from the front , I forgot that the netizens behind me were everywhere , Finally, I am tired of learning , The ability has not been improved , Bring trouble to yourself .

The same is true if you want to work in development , You can learn to develop well first , And then go and learn Linux Operation and maintenance +Linux framework .

Once a novice considers learning to develop , I suggest you learn Python The whole development of the stack , Differential development , In the future, there will be more choices for development, operation and maintenance , Instead of choosing PHP,JAVA And so on .

Sum up , How far can operation and maintenance without programming go ？

• 1、Linux（ contain shell） Has become IT Necessary skills for technical posts （ Development , database , Network and other posts ）.Linux At present, the salary of Beijing, Shanghai and Guangzhou can reach 8-15K, But if you don't quickly go deep into senior architects and Python Development , The bottleneck of future development is very big , Time is long. , It is possible that the rising space will be covered by the architecture and Python The developer is blocked , It is urgent .

• 2、Python Has become IT The development of technical posts is the necessary technology to enhance competitiveness （ Development , database , Network and other posts ）.

• 3、Linux Senior architect （ Large scale website cluster architecture ） Will also become IT The development of technical posts is the necessary technology to enhance competitiveness （ Development , database , Network and other posts ）.

therefore ,Linux Operation and maintenance +Linux framework +Python The development of these three technologies is nearly 3-5 Necessary technology for annual operation and maintenance personnel , It is also the most favorable weapon for purely developing and enhancing competitiveness .

The sequence of mastering the above three technologies can be ：

Linux Operation and maintenance +Linux Architecture or Linux Operation and maintenance +Python Development , These three technologies are closely related , Senior O & M and architect development must be able to ！

Development language for operation and maintenance personnel , The operation and maintenance personnel must give up the minority language learning , for example perl,ruby, And don't choose to deviate Linux operations php and JAVA.

Linux+(shell/Python) It is the most popular combination for operation and maintenance personnel to learn , It must be right to follow the trend ！

If you learn pure development, you can choose the following languages ：Python、PHP、Java, But these development jobs have grown to 1-2 After year , Still need to learn Linux Operation and maintenance +Linux Architecturally , This is the so-called unified IT Job skill requirements trends .
