IT Master Plan: Blueprint Strategis untuk Transformasi Digital Perusahaan

Panduan Komprehensif dari Network, Server, Aplikasi, hingga Security


Apa Itu IT Master Plan?

IT Master Plan adalah dokumen strategis jangka panjang (biasanya 3-5 tahun) yang menjadi cetak biru pengembangan infrastruktur dan sistem teknologi informasi sebuah organisasi. Ini bukan sekadar daftar pembelian hardware atau software, tapi roadmap komprehensif yang menyelaraskan investasi teknologi dengan tujuan bisnis perusahaan.

Bayangkan IT Master Plan seperti blueprint arsitek untuk membangun gedung pencakar langit—setiap komponen harus dirancang dengan cermat, terintegrasi sempurna, dan mendukung visi jangka panjang.

Mengapa IT Master Plan Sangat Penting?

Tanpa IT Master Plan yang solid, perusahaan akan:

  • ❌ Investasi teknologi tidak terarah dan boros
  • ❌ Sistem tidak terintegrasi, menciptakan data silo
  • ❌ Tidak siap menghadapi pertumbuhan bisnis (scalability issue)
  • ❌ Rentan terhadap cyber threats
  • ❌ Sulit beradaptasi dengan perubahan teknologi

Dengan IT Master Plan yang baik:

  • ✅ Investasi IT aligned dengan strategi bisnis
  • ✅ Infrastruktur scalable dan future-proof
  • ✅ Efisiensi operasional meningkat
  • ✅ Security posture yang kuat
  • ✅ Competitive advantage melalui teknologi

Komponen Utama IT Master Plan

IT Master Plan yang komprehensif harus mencakup empat pilar fundamental:

1. Network Infrastructure (Infrastruktur Jaringan)

2. Server & Storage Infrastructure

3. Application Systems (Sistem Aplikasi)

4. IT Security & Governance

Mari kita bahas satu per satu secara detail.


1. Network Infrastructure Master Plan

Network adalah jantung dari seluruh ekosistem IT. Tanpa jaringan yang robust, server tercepat dan aplikasi terbaik pun tidak akan berfungsi optimal.

2. Server & Storage Infrastructure Master Plan

Server dan storage adalah fondasi komputasi yang menjalankan semua aplikasi bisnis.

A. Server Infrastructure Strategy

Physical vs Virtual vs Cloud

1. On-Premises Physical Servers

Kapan menggunakan:

  • High-performance workloads (database, ERP)
  • Compliance requirements (data residency)

2027 95 TB 35% 140 TB $100K
2028 125 TB 30% 185 TB $120K
2029 160 TB 28% 240 TB Infrastructure refresh

Note: Include 50% overhead untuk snapshots, replicas, growth buffer

C. Backup & Disaster Recovery

Backup Strategy - 3-2-1 Rule:

  • 3 copies of data
