sysadmin

Active Directory . It is a directory service developed by Microsoft for Windows domain networks. Allows administrators to use Group Policy to ensure a consistent user experience, deploy software to multiple computers through Group Policy. If you have a domain in your company, then there must be an administrator who manages this domain, starting with adding accounts and workstations to the domain, ending with writing scripts for automatically assigning policies.

sysadmin OS administrator . System administrator who understands Windows and Linux operating systems. It is a collection of Windows administrator and Linux administrator in one bottle.

sysadmin

Know Linux.

Know the technology of networks. Routing protocols. Routing and Switching.

SCS.

Mail server administrator.

Kerio, Exchange, postfix, exim, sendmail, etc. Management of mailboxes, accounts, distribution groups. Setting up mail, antispam, antivirus, mailing lists.

sysadmin

Storage administrator . Storage system administrator. EMC Dell, HP, IBM, Lenovo, NetApp. This also usually includes tapes and backups.

sysadmin DB administrator . Specialized database administrator. Installation, connection, configuration, backup, recovery. More difficult: recovering broken data, problem solving, replication, mirroring. Good DBAs are involved in developing and optimizing code and solving performance problems. There are different databases: Oracle, MySQL, PostgreSQL. I took out MSSQL separately, since knowledge of MSSQL is required for certain types of sysadmins in the RPG scheme.

sysadmin

Support, enikey . Springboard to the system administrators. Why Enikey, you ask? Because we show users where "any key" is located when the computer asks for "Press any key". 

We support users, solve their problems, administer workstations, wipe dust from monitors. Printing, scanning, projectors, bank clients.

One should not think that it is easy to become an Enikeian. Extensive IT knowledge and the ability to find solutions to problems are required. But if you are an enikeys, then it is already easier to improve your qualifications.

sysadmin Virtualization . Administration of virtual environments. For example, VMware or Hyper-V.

sysadmin

PBX, telephony . We handle user phones, call routing, SIP, forwarding, streams. CUCM, Asterisk. We administer phones, virtual and iron PBXs. We fight noise, echoes and gaps. 

It is not clear why we are doing this, telephonists should be doing this.

sysadmin

MSSQL . Microsoft SQL Server DB Administrator. This is a separate part of the database administrators. Installation, connection, configuration, backup, recovery, recovery of broken data, problem solving, replication, mirroring. 

Very often required for 1C administration.

sysadmin

Information security . Usually security personnel belong to a different department and must report directly to the CEO. But sometimes their functions are performed by sysadmins. ACS, video surveillance, antivirus, antispam, access control, two-factor authorization, firewall, identification and elimination of vulnerabilities, updates, firmware, encryption. Many things.

I know both bezopasnikov who became admins and admins who became bezopasnikov. So the professions are related.

sysadmin Web sites . Management of everything related to sites. Web servers, proxying, balancing, failover, high avablility, clusters, farms, hosting, FTP, DNS. Often editing someone else's crooked code. At least basic knowledge of HTML, javascript is required.

sysadmin

1C administrator . 1C: Enterprise, 1C: Accounting and other terrible mixtures of accounting and programming. Knowledge of MSSQL and the ability to pick up from a backup what accountants or 1C developers killed are required. Sometimes a competent 1C developer can administer 1C. And a competent 1C developer + a competent system administrator in a pair with him is already the key to success.

You will also need knowledge of web servers, IIS in particular.

PS 1C always slows down.

sysadmin

DevOps . Development Operations. A mixture of sysadmin and developer. The directions are different depending on the development technologies and the responsibilities of the administrator. The movement is trendy, aimed at removing the barrier between developers and administrators. Engaged in integration, automation, deployment, monitoring and automation. Automation was written twice for a reason. It works closely with the development.

Good DevOps knows several branches in the sysadmin RPG framework. 

sysadmin

Engineer . Only these people should touch the server hardware. They have an idea about electrics, optics and low current. Knows how to work with both hands and head.

There are just hardware engineers. People who can replace a burnt-out screw and install a server in a rack. 

And there are other engineers. They understand all the hardware, firmware and hardware configuration from different vendors. Able to design and implement a project to solve the problem. Knows several branches in the RPG system administration scheme. Acts in conjunction with an architect, IT director, networkers, security professionals and other admins.

IT director . This is more of a management position. Knows several branches in the RPG system administration scheme. Must be a good translator from Russian to admin and vice versa. Creates conditions for the effective work of the IT department.
