resize linode.... kubernetes ?
My linode is currently slow, the characteristics or plan is shared 16GB linode, in longview my data are the following: CPU: 6 cores, 522%, Ram: 1.61Gb, swap: 177 Mb, load: 11.95, network: 18mbs, store : 47.9 Gb ……. what is saturated is load and the processors ….. I check my mysql processes consume 70% to 50% of my resources, apache 10% …….. …. I'm going to change urgently to dedicated service …… does it help to make the best decision ……….I have read about kubernetes, other comments about putting mysql on a separate server ….. I'm new to linode .. … orient me please ….. the connections are 250 on average from mysql …. the server is LAMP. It is in production and new users are entering as they contract my service … it can grow to 2000 thousand users soon and so on.

I hope this gives you a good start. Feel free to post any additional questions you have.
