This article explains to you the overview of Server-administration and Pros and Cons

What is Server-administration?

Tableau Server on Windows integrates with several components in your IT infrastructure to provide a unique self-service data analytics culture for your users. It's important that you, as a server administrator, understand how Tableau Server fits into your IT infrastructure.

The topics in this section provide information on planning, deploying, tuning, and managing Tableau Server.

If you are new to Tableau Server, and you want to deploy it in your organization, we encourage you to deploy Tableau Server as a single server in a test environment first. The easiest way to do a single-server installation and to understand the essential requirements is to follow the steps in Everybody's Install Guide(Link opens in a new window).

If you are deploying Tableau Server as part of a broader effort to transform your organization into a data-driven culture, see Tableau Blueprint(Link opens in a new window). Tableau Blueprint is a step-by-step guide to becoming a data-driven organization, whether your organization is new to modern, self-service analytics or you’ve already deployed and need to broaden, deepen, and scale the use of data.

This topic provides a brief overview of how to think about Tableau Server and how it interacts with your existing IT infrastructure.

Why do we need a system administrator?

System administrators are generally in charge of user permissions and administration for all applications and services. SysAdmins can assign user roles and manage the entire organization's IT stack – allowing everyone the access they need to certain applications and services securely.

About Application Server Administration

To enable administrators to manage server instances and clusters running on multiple hosts, Application Server provides the following tools:

  • The Admin Console, a browser-based graphical user interface (GUI)
  • The asadmin utility, a command-line tool
  • Programmatic Java Management Extensions (JMXTM) APIs

These tools connect to a server called the Domain Administration Server, a specially designated Application Server instance that intermediates in all administrative tasks. The Domain Administration Server (DAS) provides a single secure interface for validating and executing administrative commands regardless of which interface is used.

A domain is a collection of configuration data, deployed applications, and machines with a designated administrator. The domain definition describes and can control the operation of several applications, stand-alone application server instances, and clusters, potentially spread over multiple machines. When the DAS is installed, a default domain called domain1 is always installed. You work with the default domain in this guide.

To complete most of the steps presented in this guide, you will use the Admin Console and asadmin commands.

The Pros and Cons of Being a System Administrator

July 28th 2017 – SysAdmin Day. A day to celebrate the work, that often takes place behind closed doors, of System Administrators worldwide. We’re taking today to think about being a Sys Admin, in particular the pros and cons of the coveted role.

First things first, what is a Systems Administrator? Officially they are responsible for the upkeep, configuration, and reliable operation of computer systems; especially multi-user computers, such as servers. However, in reality the role and the accompanying level of responsibility is varied depending on the organisation. As such, the pros and cons probably differ depending on who you work for and what your specific role entails. So, to do this justice, we reached out to numerous SysAdmins through SpiceWorks and collected as many pros and cons as possible. Below, we have listed some of the common answers we received.

Becoming an IT Detective

Undoubtedly a pro if you have the right mindset for it, a significant part of being a system administrator is being able to diagnose problems and fix them accordingly. So, if you’re of the kind of mindset where you love a challenge and no two days the same, this role is for you.

The Importance and Real World Implications of the Role

This one could be a pro or a con depending on whether you thrive under pressure. Most organisations today rely completely on their computers/network. When something goes wrong, employees are sat twiddling their thumbs waiting for it to start working again. In the background the organisation could suffer dramatic losses to the bottom line if the network remains down for long. So, the work done behind the scenes by Sys Admins makes a huge difference in the real world every day.

The Options Open to you are Endless

As almost all companies, irrespective of size, sectors and location, use computers, System Administrators are able to apply for positions pretty much anywhere in the world. This seems to be a pro for many Sys Admins, as you don’t get pigeon-holed into a specific industry.

The Pay Isn’t Bad

Many Sys Admin positions, in the US especially, tend to pay above the average national salary. This statistic is backed by the Bureau of Labor Statistics who suggest that employment of Computer Support Specialists is set to rise by 17% by 2022 and that the median average wage is just over $60,000.

You May Often Be Taken to Your Wit’s End

Sometimes identifying a specific problem that can be hidden away deep in the network or computer can take days, even weeks. However, the exasperation sets in when you have to deal with the numerous impatient and unaccommodating customers, staff members or supervisors that, more often than not, were the original cause of the problem to begin with.

Conclusion

So, being a sys admin has both its advantages and its disadvantages. It’s important to remember both when thinking of pursuing this career path. But, whatever role you’re in, just remember important work that Sys Admins are doing behind the scenes every day. And remember to thank a Sys Admin on the 28th of July to help get Sys Admin Day celebrations underway!
