With everything go to the cloud and serverless infrastructure are sysadmin occupation becoming obsolete? what can sysadmins do to stay relevant in IT?
System administration roles are diversifying as system engineers, application engineers, deveops engineer, devops engineer, Virtualization engineer , release engineer, cloud engineer etc. Because of scale in cloud computing and additional layer of Virtualization, the infrastructure engineering is managed as a code by using automation tools such as Chef and Puppet. The rise of computing and analytics have given tremendous elasticity and stress to the back-end infrastructure by deploying distributed computing frameworks such as Hadoop, Splunk etc. Applications are scaling horizontally and vertically across the data centers. The emergence of cloud has shifted the traditional role of system admin to the cloud engineer but infrastructure design and basic system services such as mail server, DNS, DHCP remains intact.
If you want to make your career as a Linux system administrator then you need to learn the basics of Linux along with the hands on practicals. I would recommend you to go for Redhat certified System Administration full course. The videos are available on Youtube and torrent as well. RHCSA is an entry-level certification that focuses on actual competencies at system administration, including installation and configuration of a Red Hat Enterprise Linux system and attach it to a live network running network services.
Get comfortable with scripting language & automation tools
Bash for everyday scripting, putting things in cron, use it to parse logs. Bash is not limited to it by itself, you want to learn a little sed and awk, and focus a lot on regular expressions. Regular expressions can be used in most languages.
After you have spent a few weeks/months learn python. After a few weeks with python you will easily see where it makes sense to use bash vs python.
Perl is a good general purpose language to use, if you deal with lot of files or platform independent sys admin automation, including solaris & AIX. It’s a bit hard to learn but easy to use
Some of the important automation tools for system admin are
- WPKG – The automated software deployment, upgrade, and removal program that allows you to build dependency trees of applications. The tool runs in the background and it doesn’t need any user interaction. The WPKG tool can be used to automate Windows 8 deployment tasks, so it’s good to have in any toolbox.
- AutoHotkey– The open-source scripting language for Microsoft Windows that allows you to create mouse macros manually. One of the most advantageous features that this tool provides is the ability to create stand-alone, fully executable .exe files, from any script, and operates on other PCs.
- Puppet Open Source – I think every IT professional has heard about Puppet and how it has captured the market during the last couple of years. This tool allows you to automate your IT infrastructure from acquisition to provisioning and management stages. The advantages? Scalability and scope!
Stay up to date with the current generation of infrastructure standards & practices
- Analytical skills: From designing to evaluating the performance of the network and the systems
- People skills: A network and computer systems administrator interacts with people from all levels of the organization.
- Technical know-how: Administrators have to work with different kinds of computers and network equipment, so they should be familiar with how to run these
- Quick thinking An administrator must be very responsive and must be able to quickly come up with solutions to every problem that pops up.
- Ability to multi-task Administrators often deal with different kinds of problems on top of what they usually do.
It’ll be systems administration under a different title like “Cloud Engineer” and do things differently, probably using automation tools and infrastructure code management and deployment.
Coding, automation and scripting are all very important skills to have now and for the future.
Ultimately someone will need to admin the systems and deal with the operations of the tech stack. So, yes it has a future. The type of company varies tremendously, any company could use a sysadmin. It may be an unexciting job of maintaining a local file share and email server, or something challenging like keeping a thousand servers running.
