Is my computer trying to tell me something? 🤔

Dokku, Flynn, Deis Workflow, Datacol, nanobox.

Does anyone have experience with one of these? Do you recommend any?

I have been amazed by Heroku concept, however, Heroku prices seem to be a bit pricey. I have a production app to be produced in the following weeks, and I was thinking about getting a Public Cloud machine from OVH with one of the tools above.

Any suggestions?

If you were to host a PHP website in a managed hosting, able to handle 200 concurrent users and upgrade to a better plan with no or small downtime if needed, which would be your choice?

The ability to integrate a CI/CD solution would be really helpful.

Context: We are dealing with a one-time campaign at the company and we don't plan to integrate this project into our architecture, so we looking for alternative solutions where to host it and deploy it to.

Doing a straight-forward "if" seems too complicated. Let's reverse the logic.

Vagrant vs Docker.

Which one do you use? And why? 🤔

What is the best web full-stack in your opinion?

I have been working with PHP all my life, and I am looking to start something new.

Elixir, Phoenix, PostgreSQL, GraphQL, ReactJS and Redux.

Anything missing on this stack to be perfect? 🤔

What is the best alternative to cronjobs, guaranteeing high availability and jobs not being duplicated?

I've been wondering about renting a new VPS to get all my websites sorted out again. I am tired of shared hosting and I am able to manage it as I've been in the past.

With so many great people here, I was trying to put together some of the best practices and resources on how to handle the setup and configuration of a new machine, and I hope this post may help someone while trying to gather the best know-how in the comments. Don't be scared by the lengthy post, please.

The following tips are mainly from @Condor, @Noob, @Linuxxx and some other were gathered in the webz. Thanks for @Linux for recommending me Vultr VPS. I would appreciate further feedback from the community on how to improve this and/or change anything that may seem incorrect or should be done in better way.

1. Clean install CentOS 7 or Ubuntu (I am used to both, do you recommend more? Why?)
2. Install existing updates
3. Disable root login
4. Disable password for ssh
5. RSA key login with strong passwords/passphrases
6. Set correct locale and correct timezone (if different from default)
7. Close all ports
8. Disable and delete unneeded services
9. Install CSF
10. Install knockd (is it worth it at all? Isn't it security through obscurity?)
11. Install Fail2Ban (worth to install side by side with CSF? If not, why?)
12. Install ufw firewall (or keep with CSF/Fail2Ban? Why?)
13. Install rkhunter
14. Install anti-rootkit software (side by side with rkhunter?) (SELinux or AppArmor? Why?)
15. Enable Nginx/CSF rate limiting against SYN attacks
16. For a server to be public, is an IDS / IPS recommended? If so, which and why?
17. Log Injection Attacks in Application Layer - I should keep an eye on them. Is there any tool to help scanning?

If I want to have a server that serves multiple websites, would you add/change anything to the following?
18. Install Docker and manage separate instances with a Dockerfile powered base image with the following? Or should I keep all the servers in one main installation?
19. Install Nginx
20. Install PHP-FPM
21. Install PHP7
22. Install Memcached
23. Install MariaDB
24. Install phpMyAdmin (On specific port? Any recommendations here?)

I am sorry if this is somewhat lengthy, but I hope it may get better and be a good starting guide for a new server setup (eventually become a repo). Feel free to contribute in the comments.

What do you use for your side-projects regarding Anti-DDoS protection?

I have a community with 1-2k daily users hosted in Siteground. Currently, I am not experiencing any DDoS issues (mainly L4) but I used to when I was using another service provider. The trade-off is that the machine and the service I'm paying here is way more expensive.

I don't care about managing the server, but I was looking for a cheaper option to get my project with.

The stack is LAMP and it is an Invision Power Board forum.

What do you recommend? Which service(s) do you use for your projects and how do you prevent DDoS on your side?

I have working for software engineering for the past 8 years without any degree at all. However, in my latest job interviews one of the things I mainly lacked was understanding and applying the algorithmic concepts. As I hadn't maths since I left college, what would you recommend me?

I was looking for some kind of a course (it is always better when you have someone with whom you can discuss with), but such a specific one doesn't seem to exist in Portugal, and taking an entire degree because of algorithms is not an option to me.

Ideas?

PS: I am currently working, however I do understand that a new algorithmic thinking would help me in my daily job.
