What is the order in creating a corporate network?

Question

Computer networks

Need help, there is a lot of good information about network technologies, deploying operating systems (desktop and servers), configuring them, etc. But the essence of the question is what is the sequence (order) of applying technologies to deploy a corporate network in an enterprise (more than 30 machines with different operating systems) + 1C on the server. FOR EXAMPLE - 1. First you need DHCP (it is better to use software .....) 2. Set DNS (software ......) and further down the list. Are there any practical recommendations? What servers and (or) services (technologies) can or should be combined and used. How would an experienced and intelligent sysadmin do this? Or where to find it.

Answer 1

Whatever there is a mess, everything must be strictly divided. Routing, dhcp and in general everything that will be connected with the network should be controlled from the router, no third-party software for dhcp on the server, etc. All this and much more can Mikrotik. DNS - I think it means working with Active Directory, if so, then by adding roles and components on a windows server or as a bicycle alternative to samba4 on a linux server.
Security, filtering, monitoring, optimization are already separate conversations about which to write / talk for a long time. because here you need a separate approach to a specific situation. The bottom line is that there is no standard, so to speak, for the correct organization of the IT infrastructure of an enterprise. If you have any questions, write on Skype, I'll tell you.

Answer 2

Find a smart system administrator (local or remote) who can design and / or configure everything. You can look for them on the neighboring freelance exchange, on job search sites.

Answer 3

You need to design a network based on your capabilities and the capabilities of local IT specialists in organizing and supporting it, and then, according to the drafted project, plan and gradually carry out the work - each item from start to finish. The project must be done based on the needs of the company and understand what issues are being solved and what problems can be created.
