The reason why I want to write this article at this time is that IN May this year, I left the company where I worked for 5 years after graduation. After thinking about it, I would like to use this article to make a review of the past 5 years.
To introduce myself
First time writing a non-technical article.
Hello everyone, let’s introduce ourselves briefly first. Base Xi ‘an, graduated from Xi ‘an Technological University (double non-ordinary undergraduate) in automation in 2016, there are alumni of the same class can communicate with friends oh.
Into the pit
Said a “operation” pit like the sea, from now on sister for passers-by. Borrow a limerick, please enjoy:
A “operation” pit like the sea
Bow and kneel, equipment failure can not sleep at night
Boss a sound immediately in place, sesame dot matter dare not offend
In the middle of a year do not leave the post, the blame has long been used to be scolded
Physically and mentally tired no tears, every festival relatives will be difficult to meet
The salary is not high status is low, the five poisons on the poor scrap
Throw away the family house industry unworthy of their elders, not in which it is difficult to know its taste
Dare not expect social status, all rely on silly narcissism
Operational work, therefore, is really is a very challenging work, means you have to pay more energy than most people, means that you have to give up a lot of time to rest, of course, you will reap many, expands on the breadth of the knowledge and accumulate is absolutely very quickly, even may require you to have some cleverness or spiritual, The bottom line is that you can quickly understand a lot of principles to solve the problem at hand. It means 7×24 jobs. It means endless problems. It means a phone call in the middle of the night that you have to solve immediately.
So maybe…
In fact, the automation major should not be to do embedded development, C language and so on will be easier to enter some, so, today to say why I chose to do the operation and maintenance?
To tell the truth I like most in senior at the university students, let alone do operations, have never heard, so at first sign of the work is an electronics factory in shenzhen, but a coincidence, one over the weekend to go to xi ‘an university of posts and telecommunications to find students playing, joined together at the university of posts and telecommunications with his classroom training to try listening to lectures, English on the pure black Terminal interface, the teacher click do not know what the thing, and then a string of English brush up, sleep *, who can refuse a so loaded force skills, so without hesitation to break the contract has signed the electronic factory tripartite agreement, chose to register for class learning!
PS BEFORE I had time to call the HR of the electronics factory to cancel the entry, he actually contacted me and said that there were too many people to hire this year, and there was no room in the dormitory. He asked me if I could rent a room by myself, or cancel the tripartite agreement. Then cancel it decisively and avoid a wave of liquidated damages.
Work a
Position 1: Mobile engineer for IDC server restart
After graduation in July 2016, when the training was just finished, I came to Shanghai, the capital of demons. The first company was an IDC server rental + hosting + management service business model. The operation and maintenance team could be divided into two types: 1.
The work can be broadly divided into two categories:
- 1, resource allocation (including but not limited to server removal (2U is really heavy))
- 2. Resource inspection
- 3. Maintain the internal resource system
- 4. On-site technical support
Before three o ‘clock is easy to understand, for the fourth point, puts forward some technical problems, general is a customer certainly gives priority to the technical engineers up to a remote operation, but sometimes because the network reasons or the customer to crack the password, reshipment need to restart the server system, server crashing, and so on, so distance will not be able to complete the (now think of cloud computing is really convenient), After confirming the information, the field engineer (that’s me) will push the cart with the monitor, VGA cable, keyboard and mouse, and connect it to the client’s server for on-site operation.
The working environment looks something like this
Looks neat, doesn’t it?
Do you think the cabinet wiring is like this?
Ha ha ha think more, actually may be like this!
Because of remote technical support to filter out a lot of customer problems, the day of the room was at leisure to tell the truth, yes, really idle, so that the dry for more than three months less than four months, I realized that may be about to get on in this waste, just is located in xi ‘an, a subsidiary of remote technical support team to open the quota of internal transfers, so, Then I had my second job experience.
Position 2: Remote technical support
Finally, I don’t have to move and restart servers every day. I am looking forward to my new position.
The work content of the new position is mainly to deal with the problems put forward by customers in the form of work orders. Due to the large amount of work orders, I have encountered many problems at this stage and accumulated a lot of processing experience, which can be roughly divided into:
- 1. Troubleshooting and tuning
- 2. Respond to cyber attacks
- 3. Environment deployment and setup
- 4. Data backup
- 5. High availability cluster
- 6. Monitor alarms
The customer’s environment is strange, and in the customer’s server operation, must focus on the mind, uncertain, do not know, do not know the command and operation of thousands of thousands of never execute! Be in awe of operations.
One of them had an accident.
The customer reported that the server could not be remotely connected, and checked that it was a Windows server, and the network could not be pinged through. After checking the external console, a colleague on the site found that the server had a blue screen of death and was in the state of infinite restart. After trying to repair the boot, it failed, so we contacted the customer for data backup and system reinstallation.
First to the server to insert the usb flash drive and a 1 t empty disk, used to back up your data, from the U disk to start Windows PE, customers through wave hands like a cloud server operation, their data disk backup copies of data to an external disk, content is mainly about the picture and the database file, the entire process takes nearly 10 hours, after the copy, We confirmed with the customer’s work order and began to reinstall the server system after the authorization was obtained. After the successful installation, the customer began to restore the data of the backup disk to the original hard disk. It seemed that everything went well, didn’t it? A few more hours passed, the recovery was complete, we removed the external hard drive, and the customer began to deploy the environment. Restore the past data file cannot be opened, the message is damaged, GG smecta ~ ~
Position 3: Operation and maintenance development Engineer
It takes a long time to deal with work orders. In fact, there are only so many problems, big and small. I spend more time communicating with customers.
What is operational development? Operation is the same operation, development is the same development. Whichever side crosses the line is called DevOps or operations development, just as the front end tends to be full stack. It’s all a little bit of crossover. That is, you know something more than everyone else, and then you get another job.
Operation and maintenance will not be developed, it is estimated that the elimination is not far away. Of course if you like the dirty work the hard work might last a while.
Research and development will not be operation and maintenance, elimination is not, but easy to let operation and maintenance, so it will be good. At least don’t bother ops.
Job Description:
- 1. Partial requirements mining implementation methods
- Python + Django Rest Franework + CRUD
- 3, the Shell
- 4, Kubernetes
- 5, Vue
During this period, I began to touch the public cloud one by one. The early Ariyun, the later Tencent Cloud, Huawei Cloud and AWS all used the public cloud. Compared with IDC, the public cloud was so fragrant that I once thought that the basic operation and maintenance would even be outlawed by the public cloud.
I successively obtained some certificates of public cloud, such as ACP of Aliyun, TCA of Tengyun, SAA and SAP of AWS, and CKA of Kubernetes.
These certificates in the work of the actual role is not very big, but the process of obtaining the certificate is to grasp the knowledge point of each certificate.
Work two
Thinking about leaving
In May this year, I still decided to leave the old company. To be honest, the people in the old company are very good, and I have had a great growth. Since graduation, the breadth of my technology now mostly benefits from various scenarios at that time, but I still chose to leave.
Not for anything else, because of money, because of poverty.
Because of the pressure of mortgage and parking space loan, the down payment is also borrowed, so the money left this place.
Open Boss Zhipin
I sent out my resume casually. I saw that this position was recruiting on Boss Zhipin. After reading about the job content, I was very interested, so I contacted HR and sent out my resume.
Interview four rounds ashore
The first and the second are technical issues. The technical issues mainly revolve around Kubernetes, including components, cluster network, principles, life cycle, blot, scheduling, controller, resource limitation, etc., as well as CICD and Python related knowledge. Overall, the interview experience is excellent, and the interviewers are Nice. There are a few questions I thought for a while feel good trouble to directly say don’t know, the interviewer also guided me to finally say the answer, did not expect the interview can also learn something.
The three sides mainly asked about the difficulties encountered in the project, what roles they played and what they learned from it. After about half an hour’s chat, I received a text message.
The four sides are the HR interview, mainly to discuss the reason for leaving, career planning, and finally received the salary email, offer, the whole interview process is over.
By the way, I am currently mainly engaged in container operation and maintenance related work
Write in the last
From server mobility engineers, to public cloud computing, to container orchestration, the industry is growing too fast, lazy and cost compression is the driving force, alas, learn, learn, too deep.
hiring
Let me make an advertisement for you, friends in Xi ‘an, Tencent Cloud subsidiary is currently recruiting a large number of people, front-end development, background development, operation and maintenance are a lot of holes, if you have ideas friends can send your resume to my email ~ ~
