Game industry high defense CDN how to choose to protect the smooth operation of the game

To be honest, last year, our hand tour on the first day of the line was paralyzed by the experience, and now I think of it still have palpitations. Seeing the players crazy influx, the server suddenly jammed into PPT, and then directly black screen, the operation group instantly exploded, the technical small brother's face is green.

Later, a check, good guy, 300G + DDoS traffic directly paste face, ordinary CDN like paper mache was stabbed through.

After that time I learned the hard way, in North America and Asia-Pacific market crawling and rolling, tuition paid enough to understand the doorway of this high-defense CDN.

Select high defense CDN, at first glance don't be those who are sky-high "T-level defense", "unlimited protection" fooled crippled. Last year, I tested a service provider called "1T defense", the price is ridiculously cheap, the results of simulated attacks just to 200G on the hiatus, the background nodes all red. Really happened to SYN Flood mixed with UDP reflection attacks, no real ability to vendors kneel in seconds.

Then I learned that it depends on whether they have a large cleansing center, preferably a core hub like Los Angeles, Tokyo, or Frankfurt with its own server room, rather than second-hand rented bandwidth.

Node quality is ten times more important than quantity. Once I used a cheap service that boasted of "500 nodes around the world", and found that Southeast Asian players complained about lag.

I'm not sure if you're going to be able to find the best way to do this, but I'm sure you're going to be able to find the best way to do it! The game is a 50ms difference between being able to roll a move and not being able to put out a skill.

Hidden cost pitfalls.

A quotation written $0.05/GB looks very fragrant, and so the bill came to realize that the WAF rules, CC protection, SSL acceleration to additional money, CC attacks automatically triggered by the elastic bandwidth is a bottomless pit.

Now use this although the base price is expensive 20%, but the WebSocket long connection support, TCP acceleration, all protocols HTTPS are packaged in the middle of the night three o'clock when attacked and watched the console traffic curve soared to 400G and fell back steadily, the feeling is only called down-to-earth.

Technical support is what keeps you alive.

There was a Christmas event back in the day, and suddenly at 2:00 am I was hit with a freak packet attack and couldn't even log in to my own backend.

At that time in desperation to the supplier of the emergency channel to send a message, I did not expect three minutes on the engineers to call the transatlantic phone over, with an accent in English to listen to a particularly friendly, ten minutes to cut the alternate cleaning strategy to get it done.

I later learned that they have a 24-hour war room in Phoenix that specializes in keeping an eye on gaming customers, and that kind of service really isn't something you can get with a cheap package.

Now with the gang of grandchildren to play more guerrilla fight also feel the way out of the door. Weekly penetration tests can not be saved, and every month you have to let the technology to do a real traffic pressure test.

Last week, I looked at the report and found that there was a newly emerged attack pattern that specialized in hitting game matching servers, which immediately made the CDN vendor update the targeted fingerprinting rules.

Doing games these days, technology selection is an arms race, high-defense CDN selected, players scolded the server lag can be less than eighty percent of the bad reviews - this is the real money for the lessons learned.
