Apa Yang Dikerjakan Oleh System Administrator Sepanjang Hari?

Posted in Opini, Teknis, Kejadian Terbaru, Obrolan IT, Obrolan Santai, Informasi by indra on the July 25th, 2014

Ini adalah terjemahan dari artikel saya di blog SimplerCloud disini.

Hari ini, 25 Juli 2014, adalah Hari Apresiasi System Administrator, yang merupakan ajang untuk menunjukkan apresiasi bagi para system administrator (sysadmin) dan pekerja TI lainnya. Ajang ini dirayakan setiap hari Jum’at minggu terakhir di bulan Juli setiap tahunnya, sejak tahun 2000.

Sebagai seorang administrator sistem dan jaringan (network) selama 15 tahun, saya mengetahui secara langsung mengenai banyaknya pekerjaan sysadmin yang harus dikerjakan, keterampilan (skill-sets) dan pengetahuan (knowledge) yang harus dipelajari, dan pekerjaan yang berat serta dengan jam panjang yang harus dikerjakan. Namun kadang-kadang, pengguna (user) biasa mungkin tidak terlalu mengenal sysadmin, seperti hal-nya sysadmin mengenal user-user mereka. Itulah sebabnya kenapa Hari SysAdmin adalah hari yang mengagumkan, yang setiap orang harus merayakan.


Treat sysadmin Anda hari ini, karena 25 Juli 2014 adalah Hari SysAdmin Sedunia
Apa sih sebenarnya pekerjaan dari system administrator itu, dan mengapa kita perlu menghargai pekerjaan mereka? Menurut definisi Wikipedia, seorang system administrator adalah yang bertanggung jawab dengan pemeliharaan, konfigurasi dan operasi yang handal dari sistem komputer, terutama komputer multi-pengguna seperti server.

Dalam istilah awam, system administrator mengelola semua server, perangkat jaringan dan infrastruktur IT lainnya bagi sebuah organisasi. Di banyak perusahaan, system administrator tersebut adalah bagian dari tim atau departemen TI. Merekalah yang melakukan konfigurasi jaringan di organisasi tersebut, instalasi mail server, file server dan banyak server lain yang dibutuhkan oleh organisasi tersebut. Mereka jugalah yang melakukan instalasi semua aplikasi yang diperlukan untuk mendukung bisnis organisasi tersebut, melakukan update sistem operasi, patching, perubahan konfigurasi, dan lain-lain. Mereka bertanggung jawab untuk memastikan bahwa semua layanan berjalan dengan baik.

Sebagai contoh, system administrator bertanggung jawab untuk memastikan bahwa koneksi internet di kantor bekerja dengan baik, mail server berjalan dengan baik dan memproses semua email yang dikirim dan diterima oleh semua staf dalam organisasi. Tanpa basic operations ini, Anda tidak akan dapat melakukan apa-apa yang membutuhkan koneksi Internet, seperti mengakses web atau memeriksa email Anda. Dan bahkan jika koneksi Internet Anda bekerja, Anda tidak akan dapat mengirim / menerima email jika mail server organisasi Anda sedang down.


Sysadmin membuat manajer terlihat baik, tapi sayangnya manajer sering tidak bisa memahami mereka.
Ada berbagai jenis system administrator berdasarkan peran dan tanggung jawab mereka. Sebuah perusahaan besar mungkin memiliki system administrator yang berbeda untuk peran yang berbeda, tetapi untuk perusahaan yang lebih kecil, sebagian besar peran yang berbeda tersebut mungkin ditangani bersama oleh hanya beberapa system administrator saja, atau bahkan satu orang saja. Beberapa jenis system administrator tersebut adalah:

  • Administrator server - menangani sistem operasi server, dan sampai batas tertentu, aplikasi-nya juga, seperti layanan mail, layanan web, dan lain-lain. Mereka juga yang bertugas untuk melakukan troubleshooting masalah yang berhubungan dengan perangkat keras, sistem operasi atau aplikasi.
  • Administrator jaringan - memelihara infrastruktur jaringan, seperti router dan switch, dan melakukan troubleshooting masalah yang terkait dengan jaringan.
  • Administrator basis data (database administrator/DBA) - memelihara sistem basis data yang digunakan oleh organisasi. Dalam organisasi besar yang menggunakan basis data yang lebih besar dan lebih kompleks, ada DBA yang secara khusus bertanggung jawab untuk peran ini. Dalam organisasi yang lebih kecil, peran ini biasanya dilakukan oleh administrator server.

Tidak seperti banyak profesi lain seperti pilot, dokter dan lain-lain, tidak ada jalur akademis atau pelatihan khusus untuk menjadi system administrator. Walaupun kebanyakan system administrators adalah lulusan di bidang ilmu komputer, teknologi informasi atau bidang lain yang serupa, setiap orang benar-benar dapat menjadi system administrator dengan cara belajar sendiri dan, dalam banyak kasus, pelatihan waktu kerja (on the job training). Ada beberapa program pelatihan dan sertifikasi untuk bidang IT spesifik, seperti pelatihan dan sertifikasi Microsoft untuk sistem berbasis Microsoft dan aplikasi seperti Microsoft Windows dan SQL, pelatihan Cisco dan sertifikasi untuk jaringan Cisco, dan lain-lain.

Kebanyakan system administrator selalu siap menerima teleopn kapan saja (on-call standby), karena mereka memiliki sistem dan infrastruktur jaringan yang harus berjalan 24×7. Ini berarti, seorang system administrator bisa mendadak ditelepon jam 3 pagi jika mail server sedang down, atau koneksi Internet tiba-tiba mati. Yang paling penting, mereka lah orang-orang yang memastikan bahwa bahwa semua server berfungsi dengan baik, seluruh jaringan berjalan dengan baik, sepanjang waktu.

Itu sebabnya, kebanyakan system administrator yang baik itu terlalu banyak bekerja, dan sangat banyak dibutuhkan, dan sekarang, mereka sangat penting untuk keberhasilan aplikasi Internet, web dan perusahaan berbasis cloud.

“Ini bukan sihir, ini bakat dan kerja keras”

Itu sebabnya, pada tahun 2000 lalu, seorang system administrator bernama Ted Kekatos menyarankan acara hari tahunan dimana semua orang dapat menghargai kerja administrator sistem dengan - misalnya - memberi mereka kue dan es krim dan mengadakan pesta kecil atau perayaan. Ajang ini telah menjadi acara tahunan, yang dirayakan setiap tahun pada hari Jumat terakhir bulan Juli. Hari ini menandai tahun ke-14 kita merayakan Hari Apresiasi System Administrator.

System administrator yang baik tidak pernah berhenti belajar, dan akan menggabungkan banyak skill-set untuk melakukan banyak pekerjaan berbeda dan tak ada habisnya. Saya mengucapkan Selamat Hari System Administrator untuk semua system administrators, dimanapun Anda berada.

What do system administrators do all day?

Posted in Happening, information, thoughts, technical, Greetings, simplercloud by Indra Pramana on the July 25th, 2014
This article is originally posted on SimplerCloud's blog here.


Today (25 July 2014) is System Administrator Appreciation Day, which is an event to show appreciation for the work of system administrators (or sysadmins) and other IT workers. It is celebrated on the last Friday of July every year, since the year 2000.

As a hardened, 15-year veteran system and network administrator, I know first hand about the many tasks a system administrator needs to do, the skill sets and knowledge he needs to learn, and with the daunting tasks and long hours he has to keep. Yet sometimes, normal users would not know their system administrators as well as the system administrators know their users. And that is why System Administrator Day is an awesome day that everyone should celebrate.

Treat your system administrator today, because 25 July is World System Administrator Appreciation Day

What do system administrators do, and why do we need to appreciate their work? According to Wikipedia‘s definition, a system administrator is a person who is responsible for the upkeep, configuration, and reliable operation of computer systems; especially multi-user computers, such as servers.

In layman’s terms, system administrators manage all the servers, network equipment and any other IT infrastructure for an organisation. In many companies, those system administrators are part of the organisation’s IT team or department. They are the one who setup the network within the organisation, installing mail servers, file servers and many other servers required by the organisation, installing all the required applications to support the organisation’s business, applying operating system updates, patches and configuration changes, among others. They are responsible to ensure that all the services are running.

For example, system administrators are responsible to ensure that Internet connection in the office is working, the mail server is running and processing emails tht are sent and received by all staff within the organisation. Without these basic operations, you will not be able to do anything which requires Internet connection, such as surfing the web or checking your emails. And even if your Internet connection is working, you won’t be able to send/receive emails if your organisation’s mail server is down.

System administrators are indispensable to managers (Source: http://dilbert.com/strips/comic/2004-01-11/)
Sysadmins make managers look good, but managers often misunderstand them (Source: Dilbert.com)

There are different types of system administrators based on their roles and responsibilities. A bigger company might have different system administrators having different roles, but for smaller company, most of the different roles might be shared by just a few system administrators, or even one single person. Some of the different types of system administrators are:
  • Server administrator – maintains the operating system of the servers, and to some extent, the applications as well, such as the mail services, the web services, etc. He is also in-charge of troubleshooting any hardware, operating system or application related problems.
  • Network administrator – maintains the network infrastructure, such as the routers and switches, and troubleshoot network-related problems.
  • Database administrator (DBA) – maintains the database system used by organisation. In bigger organisation which uses bigger and more complex databases, there is a DBA which specifically responsible for this role. In smaller organisation, this role would normally be shared by the server administrator.

Unlike many other professions like pilots, medical doctors, etc, there is no single path of training to become a system administrator. While most system administrators have a degree in computer science, information technology or any other similar fields, anyone can actually become a system administrator by self learning and, in most cases, on-the-job training. There are some training and certifications intended to specific IT fields such as Microsoft training and certification for Microsoft-based systems and applications such as Microsoft Windows and SQL, Cisco training and certification for Cisco network, etc.

Most system administrators are always on-call, since they have system and network infrastructure which needs to run 24×7. That said, a system administrator can get paged or called at 3am in the morning when a mail server goes down, or when the Internet connection suddenly stops working. But the most important thing is that they are the one who ensure that all servers are functioning, the network is running and healthy, all the time.

That’s why good system administrators are often overworked and very much in demand, and, nowadays, crucial to the success of Internet app, web application and cloud-based companies.

“It’s not magic, it’s talent and sweat.”




That’s why, way back in the year 2000, a system administrator named Ted Kekatos suggested a yearly day event when everyone can appreciate the work of system administrators by – for example – giving them cake and ice cream and throwing a small party or celebration. This has become an annual event, celebrated every year on the last Friday of July. Today marks the 14th year we are celebrating System Administrator Appreciation Day.

Good system administrators never stop learning, and combine multiple skillsets to perform many different and unending tasks.   I wish all system administrators everywhere a very happy System Administrator’s Day.

Home Reno: Kids Room

Posted in bedroom, kids furniture, home reno by Blogger on the June 10th, 2014
The only room that's pretty much done is my twin boys' bedroom.  I designed the room to be a loft bedroom, while the boys take part in choosing the wall paint color and the flooring. We also discussed the room layout together :)  We didn't purchase any new furniture for this room. The only thing that's 'new' is an old rocking chair made of teak wood, which we got from granny in Jepara.

Home Reno - Week 27

Posted in bedroom, lighting, home reno by Blogger on the June 8th, 2014
No, our home reno is not finished. The master bathroom is not done yet, but since the reno is long overdue, we decided to move in! Yes. No kidding. Since the house is still in mess, here's a glimpse of my bedroom only. Not bad, eh?  Yeah the truth is, the other half of my bed  is cluttered with unorganized clothings and other random stuff :p
