I believe that these months you must have experienced such a scene: open the browser, click open favorites in the commonly used website, the results of the website 502, a face meng force, feel is not their own network hung again? Open a new TAB according to your age, knocked on 163 or the website of baidu, find incredibly even, meal for two seconds to realized that Google/facebook/reddit/twitter really hung up.

The summer of 2019 has been a quentin Tarantino movie in code for the Internet, with a distinct aesthetic of violence, albeit a tabletop keyboard, absent flying plasma, samurai swords, deep inner monologues and slightly banal invatribes.

Let’s take a look at some of the dead in recent months:

Not only service providers, but Cloudflare, a veteran CDN accelerator, was not immune, experiencing a massive outage on July 3 due to server overload. More than 9% of the world’s websites use Cloudflare’s services, and thousands of popular websites have been affected by the outage.

As a supplier of enterprise R & D management solutions, CODING also boldly analyzes the reasons for this wave of service leakage in major manufacturers:

1. Software complexity

With technology innovation and new services, the complexity and sophistication of software applications has reached an unprecedented level, with no sign of a brake, resulting in the inability of even the world’s best technology companies to maintain high stability.

2. The capacity overflows

Internet infrastructure has a cyclical effect. At the end of each cycle, the volume of services approaching the limit of the infrastructure will cause instability, requiring new infrastructure technologies to solve the problem, such as our transition from dial-up Internet to fiber optic era.

Because it’s summer, everyone has gone on holiday

The welfare system of foreign company is better, there is always the custom of vacation, especially in summer. A wave of engineers went on vacation and their work was assigned to someone else, causing service to falter for reasons such as unfamiliarity or proficiency.

4. Interns take over

Graduation season brings a lot of new employees and interns, and for a variety of reasons bad code written by new employees can get updated into production and cause a lot of damage.

5. The intern takes the pot Ver

It is also because a large number of new employees join the company and many senior engineers are required to give guidance, but people’s energy is limited. Many engineers spend less time writing code after allocating their energy to new employees, which leads to unstable service.

6. Conspiracy theories

Probably used by some hacker group to practice.

7. The metaphysics

Water regurgitation.

All jokes aside, the stability of service has become the lifeline of enterprises in the digital era, and the burden of maintaining the normal operation of business and ensuring the stability of the system also falls on the shoulders of the operation and maintenance engineers of each company. The so-called operation and maintenance is no small matter, and the service does not stop, and the operation and maintenance does not rest.

On Sunday, July 21, CODING, Tencent Cloud and Tencent TEG technology engineering business group will jointly hold the first Tencent Operation and maintenance Technology Open Day, aiming to share and exchange Tencent’s internal experience in operation and maintenance, and build an operation and maintenance technology ecosystem for common communication and progress both inside and outside Tencent. This event will invite four speakers with rich experience in operation and DevOps to share their unique insights on operation and maintenance work and development in the new era, and jointly create an operation and maintenance feast.
