Maid Service? Wow.
Company I work at was developers only- no network or system administration experience. Linux servers had individual password files. All were wide open to the Internet. Password grinding as 24/7 against all the boxes. No VPN, no redundant networking, servers strewn all over the place.
Internet crashed daily in the form of the shitty router they were using refusing to hand out any DNS servers but itself and proxying all queries- except of course the proxy service crashed all the time. All third party SaaS services were managed independently. Building a new environment- even in AWS- took a full day and was never done right. File systems were not put in /etc/fstab. Services did not have startup scripts in /etc/init.d. Box would get rebooted and nothing would work. Despite a data set that grows constantly- file systems were not run on top of LVM so there was essentially no way to grow them easily when they ran out of space. Corporate laptops were whatever they could buy at the local Best Buy, or Dell, or wherever.
Myself and another guy came in as the "infrastructure team". Replaced broken Internet router with redundant routers connected to two ISPs and running VRRP and OSPF. AWS servers were moved to a VPC and redundant VPN tunnels using BGP were put in place. Security was completely restricted to internal and VPN access only. 12 random 100 Mb and 1 Gb switches were replaced with a pair of HP 5406zl2 switches running OSPF and VRRP.
Active Directory was set up to provide centralized authentication for the Linux servers and management of the desktops. Linux boxes were configured with SSSD.
Active Directory Certificate Services was implemented to provide certificate services for the environment (including an offline root CA and multiple intermediary CAs). WDS/MDT was implemented to provide a sane and consistent system image including bitlocker encryption for all the laptops. Laptops were standardized to two systems- one for developers and one for everyone else- which also made the WDS/MDT config at least remotely sane.
Random wireless access points were replaced with a Unifi system. All offices are now updated regularly and managed from a central location. Wireless was switched from PSK to Enterprise authentication using RADIUS against a Microsoft NPS server. Switches and routers also authenticate with RADIUS.
GAPS was implemented to sync Google Apps passwords from AD. Active Directory Federation Services were implemented to provide SSO using SAML and OAuth for all our 3rd part SaaS providers. Users now have a single username and password to remember.
There were probably 2 dozen other major changes made and we're still improving things.
Maid Service? I suppose that's one way to look at it. Then again- I get paid more than all the developers so what do I care. Maid Service? Sure thing sir! Would you like a mint on your server?
