The SaaS Revolution in Engineering Mechanics

I. The Dilemma of Traditional Software Models

Traditional engineering simulation software adopts a model of local installation, perpetual licensing, or annual subscription. This model has exposed more and more problems in today's rapidly developing technological environment.

High Initial Investment

The acquisition cost of traditional engineering simulation software is prohibitive:

Software licensing fees: Annual licensing fees for a single copy of ANSYS, ABAQUS and other software range from 100,000 to 500,000 RMB
Hardware investment: Need to configure high-performance workstations, costing 50,000 to 200,000 RMB per unit
IT infrastructure: Investment in servers, storage, networks and other facilities
Personnel training costs: Professional training fees and learning time costs

For small and medium-sized enterprises, research teams, and university laboratories, such initial investment constitutes a huge barrier.

The Burden of Maintenance and Upgrades

Software maintenance: Regular updates, patch installations, bug fixes
Hardware updates: As model scale increases, hardware needs continuous upgrades
IT operations: Requires dedicated IT personnel for system maintenance
Version compatibility issues: File compatibility between old and new versions, integration with other software

Low Resource Utilization

Idle waste: High-performance workstations are idle during non-working hours
Peak-valley imbalance: Insufficient computing power during project peaks, excessive at other times
Cannot share: Difficult to share computing resources between different departments and projects
License restrictions: Concurrent user limits cause queuing and waiting

II. Core Advantages of the SaaS Model

RFPA Cloud adopts the SaaS (Software as a Service) model, completely changing the delivery and usage of engineering simulation software.

Zero Initial Investment, Pay-as-You-Go

The biggest advantage of the SaaS model is lowering the barrier to entry:

No need to purchase software: Access through a browser, no local installation required
No need to invest in hardware: Computation is performed in the cloud, ordinary laptops can be used
Pay-per-use: Pay according to actual computing resources and time used
Flexible packages: Provide multiple package options such as starter, research, and professional versions

Cost comparison example:

Traditional model: Software 300,000/year + Hardware 200,000 + Personnel 100,000/year = 600,000 first year, 400,000/year thereafter
SaaS model: Starter version 2,388/year, Research version 8,388/year, Professional version 17,988/year

Costs are reduced by more than 95%, allowing more individuals, teams, and SMEs to use advanced simulation tools.

Elastic Scaling, Unlimited Computing Power

Cloud deployment brings unprecedented flexibility:

On-demand allocation: Automatically allocate computing resources according to task requirements
Rapid scaling: A single task can call hundreds or thousands of CPU cores
Parallel processing: Multiple tasks run simultaneously without interference
Unlimited storage: Cloud storage space, not limited by local disk

A small research team can temporarily call computing power equivalent to dozens of high-performance workstations when large-scale calculations are needed, while paying only the basic service fee at other times.

Continuous Updates, Never Outdated

Automatic updates: New features and algorithms go online automatically, users upgrade seamlessly
Instant bug fixes: Problems are immediately fixed in the cloud after discovery, benefiting all users
Compatibility guarantee: Unified cloud environment, no version compatibility issues
Long-term support: Historical project files are permanently accessible and runnable

III. A New Paradigm of Collaborative Work

The SaaS model not only changes the way software is used, but also changes the way teams collaborate.

Cloud Collaboration

RFPA Cloud supports multi-person, multi-location, multi-terminal collaborative work:

Real-time sharing: Project members can view the latest models and results in real time
Permission management: Flexible role and permission settings to protect data security
Version control: Automatically save historical versions, support rollback and comparison
Comment and discussion: Directly annotate and discuss on models and results

Mobile Office

Multi-terminal access: Accessible from PC, tablet, and mobile phone
Anytime, anywhere: Not limited by location, can work at home or on the road
Lightweight client: No need for high-performance devices, ordinary devices can be used smoothly
Offline mode: Key data can be viewed offline and synchronized when network is restored

Cross-Organizational Cooperation

The SaaS model makes cross-organizational cooperation easier:

Project sharing: Easily share projects and data with partners
External consultants: Convenient to invite external experts to participate in projects
Supply chain collaboration: Information transparency among design, manufacturing, and construction parties
Data interface: API interface supports integration with BIM, GIS and other systems

IV. Data Security and Privacy Protection

Many users worry about data security issues with the SaaS model. RFPA Cloud takes strict measures in data security.

Multi-Level Security Assurance

Data encryption: Full encryption of transmission and storage (TLS 1.3 + AES-256)
Identity authentication: Multi-factor authentication, single sign-on (SSO) support
Access control: Fine-grained permission management based on roles
Security audit: Complete operation logs, traceable audit

Data Sovereignty

Data ownership: User data belongs to the user, the platform cannot misappropriate it
Data isolation: Physical isolation of different user data to avoid leakage
Data export: Users can export all data at any time
Account cancellation: Data is completely deleted after account cancellation

Private Deployment Option

For enterprises and institutions with special security requirements, RFPA Cloud provides private deployment solutions:

Local deployment: Deploy on the customer's own servers
Dedicated cloud: Deploy in the cloud environment specified by the customer
Hybrid cloud: Sensitive data stored locally, computing tasks executed in the cloud
Domestic support: Support for domestic operating systems and chips
