What is the difference between private VPS architecture and shared (multi-tenant) architecture?

In multi-tenant architecture, multiple customers share the same server and database. In single-tenant (private VPS) architecture, each customer has their own dedicated server and database. Rapitek provides each customer with a dedicated VPS, ensuring full data isolation.

How is private VPS CRM better in terms of security?

Your data never resides on the same server or database as any other company. A security vulnerability at another customer does not affect your data. Isolated architecture makes meeting KVKK and data protection requirements easier.

Is my data hosted in Turkey?

Yes. Rapitek CRM data is hosted in data centers in Turkey. With private VPS architecture, you know exactly which server and location your data is stored on. KVKK compliance is ensured at the architectural level.

Is there vendor lock-in risk? How can I get my data?

Zero vendor lock-in. You can export all your data at any time in standard formats (CSV, Excel, SQL dump). You have direct access to your dedicated database. Your data is yours, with no restrictions on departure.

Does private VPS architecture increase costs?

Rapitek offers transparent and competitive pricing. Considering the security, performance, and flexibility that private VPS provides, the cost-benefit ratio is very high. No hidden fees or surprise costs.

What are the customization levels? How deep can we go?

Dedicated server architecture enables unlimited customization. Database structure changes, custom module development, integration APIs, automations -- all possible. Customizations that are restricted in shared systems are fully available with dedicated VPS.

How do backup and data recovery work?

Each customer has an independent backup plan. Daily automatic backups and on-demand instant snapshots. With private VPS architecture, backup schedules, frequency, and retention periods are under your control.

5 Critical Benefits of Dedicated VPS Architecture

Complete Data Isolation

Your data never resides in the same database as any other company's data. The risk of data mixing or unauthorized access that occurs in shared systems is zero.

Data Sovereignty

Your data is in data centers in Turkey, on servers you know and control. You will not experience cross-border data transfer issues under KVKK Article 9.

Zero Vendor Lock-in

Export all your data at any time in CSV, Excel, or SQL dump formats. You have direct access to your own database. Your data is yours, and you have full control over it.

Unlimited Customization

Dedicated server architecture enables deep customization. Database structure modifications, custom module development, complex integrations — everything that is restricted in shared systems is possible with Rapitek.

Performance Guarantee

No noisy neighbor problem. Another customer's heavy usage cannot degrade your performance. CPU, RAM, and disk resources are allocated exclusively to you. Consistent and predictable performance.

Independent Backup

Independent backup plan dedicated to each customer. Daily automatic backups, instant snapshots when needed. Backup times, frequency, and retention period are under your control.

Technical Architecture: How Does It Work?

Rapitek CRM's single-tenant architecture in simplified form. Technical details in accessible language.

1

Dedicated VPS Server for Each Customer

When you register with Rapitek, a dedicated virtual server (VPS) is provisioned for you. This server hosts only your data and is not shared with any other customer.

Technical Detail: Each VPS has its own CPU, RAM, and disk resources. Example: 4 CPU cores, 8GB RAM, 100GB SSD. These resources are guaranteed and not shared with others.

2

Isolated Database

On your VPS, only your database runs. Your customer records, sales opportunities, reports — all data never resides in the same database as any other company.

Security: In shared systems, SQL injection or authorization errors affect all customers. In an isolated database, this risk does not exist.

3

Independent Backup Infrastructure

Each customer has their own backup schedule . Daily automatic backups, weekly archives, instant snapshots when needed. Backup times are adjusted according to your business hours.

Flexibility: In shared systems, backup times are fixed and cannot be changed. In a dedicated VPS, you decide.

4

Dedicated SSL Certificate

Each customer receives a dedicated SSL certificate for their own domain . Example: crm.yourcompany.com to access the system. Not a wildcard certificate, but one dedicated to you.

Branding: In shared systems, you typically use yourcompany.salesforce.com subdomains. With Rapitek, you use your own domain.

5

Dedicated Resources

CPU, RAM ve disk kaynakları sadece sizin. Başka bir müşterinin yoğun kullanımı sizin performansınızı etkilemez. SLA garantileri gerçekçi ve tutturulabilir.

Noisy Neighbor: Multi-tenant sistemlerde sık yaşanan problem. Başka bir müşteri veri import ederken siz beklersiniz. Single-tenant'ta bu yoktur.

Sonuç: Mimari, Stratejidir

Rapitek CRM'in single-tenant mimarisi bir teknoloji seçimi değil, bir müşteri odaklılık stratejisidir. Paylaşımlı sistemlerde sağlayıcı maliyet optimize eder, single-tenant'ta müşteri deneyimi optimize edilir. 200+ proje deneyimimizle gördük: Mimari, sonradan değiştirilemeyen bir karardır. Biz doğru mimariyle başladık.

KVKK Compliance: Protection at the Architecture Level

Özel VDS mimarisi KVKK gereksinimlerini doğası gereği karşılar. Uyumluluk bir özellik değil, mimarinin sonucudur.

KVKK Madde 9: Veri Yerleşimi (Data Residency)

"Contactsel veriler, ilgili kişinin açık rızası olmaksızın yurt dışına aktarılamaz."

Rapitek Approach: Tüm veriler Turkey'deki veri merkezlerinde. Özel VDS mimarisi sayesinde verilerinizin hangi fiziksel sunucuda olduğunu bilirsiniz. Yurtdışına veri aktarımı riski yoktur.

KVKK Madde 12: Veri Güvenliği

"Veri sorumlusu, kişisel verilerin hukuka aykırı olarak işlenmesini ve erişilmesini önlemek zorundadır."

Rapitek Approach: Tam veri izolasyonu (single-tenant). Başka bir müşterideki güvenlik açığı sizin verilerinize erişemez. Paylaşımlı veritabanı riski yoktur.

KVKK Madde 11: İlgili Contactnin Hakları (Veri Taşınabilirliği)

"İlgili kişi, kendisi tarafından sağlanmış kişisel verilerin bir başka veri sorumlusuna aktarılmasını isteme hakkına sahiptir."

Rapitek Approach: Unlimited veri export. CSV, Excel, SQL dump — istediğiniz formatta, istediğiniz zaman. Proprietary format yok, vendor lock-in yok.

KVKK Madde 10: Veri Sorumlusu Kontrolü

"Veri sorumlusu, veri işleme faaliyetleri üzerinde tam kontrol sahibi olmalıdır."

Rapitek Approach: Özel veritabanınıza doğrudan erişim. Yedekleme zamanlamanızı siz belirleyin. Silme işlemlerini siz kontrol edin. Tam veri egemenliği.

KVKK Uyumluluğu: Built-in, Bolt-on Değil

Multi-tenant sistemlerde KVKK uyumluluğu sonradan eklenen (bolt-on) bir özelliktir. Sözleşmeler, DPA'ler, TIA formları — karmaşık dokümantasyon gerekir. Rapitek'in single-tenant mimarisinde KVKK uyumluluğu mimari düzeyinde yerleşiktir (built-in). Verileriniz Turkey'de, izole sunucuda, tam kontrolünüzde. Uyumluluk bir sonuçtur, ek bir çaba değil.

Who Is It Ideal For?

Regulated Industries

Banking, insurance, healthcare, pharmaceutical industries — data security and compliance are critical. Multi-tenant systems may not be accepted by regulatory bodies.

High Security Requirements

Trade secrets, patent information, strategic customer lists — companies with sensitive data. Data leak risk is unacceptable.

Deep Customization Requirements

Standard CRM features are not enough. Custom modules, complex workflows, and industry-specific integrations are needed.

Data Sovereignty Sensitivity

You want to know exactly where your data is located. You cannot trust global cloud providers. Controlled infrastructure in Turkey is essential.
