AI 運用実践ガイド

According to the Financial Times, startup failures are up 60% as founders feel the hangover after the boom, even in the middle of the AI funding frenzy. Millions of jobs are at risk at VC-backed companies, so the stakes are high for AI startups navigating these choppy waters. The biggest challenge isn't having the best unique idea but navigating operational challenges.

We'll discuss the following topics any AI operation should be considering:

• Build vs. Buy
• Performance and Efficiency
• Scaling Considerations
• Security, Privacy, and Compliance

1. Build vs. Buy

It’s no surprise that the latest GPUs and specialized hardware come with a big price tag. Many operations are caught in the question of build vs buy: 

• Pay for on-demand cloud computing resources in pursuit of usage flexibility with higher long-term costs
• Or invest in dedicated infrastructure for long-term savings while risking drops in usage

This tradeoff can be daunting for AI operations that must balance agility with cost control. The choice becomes even more critical as training demands and deploying large models grow exponentially with increasing computing demands. 

Here's a quick breakdown of the complexities behind this decision:

On-Demand Cloud Resources

Advantages

• Flexibility: Startups can scale usage up or down based on immediate needs, avoiding upfront capital expenditure.
• Accessibility: No need to wait for hardware procurement or deal with maintenance overhead.
• Expertise: Cloud platforms have experience deploying, configuring, integrating, and maintaining resources for various usages, which reduces expertise costs.

Challenges

• Higher Long-Term Costs: Over time, the premium charged for on-demand usage can add up, especially for startups with consistent or growing needs.
• Usage Waste: Poor planning or resource over-provisioning can lead to unused capacity, inflating costs unnecessarily.
• Reserve in Advance: Cloud providers tend to only provide access to cutting-edge GPUs to customers who reserved months in advance.

Owning Dedicated Infrastructure

Advantages

• Cost Efficiency: Long-term savings by avoiding recurring cloud costs.
• Privacy: Having control over your own on-prem hardware mitigates the possibility of security or data privacy leaks.

Challenges

• Capital Investment: High upfront costs make this option less feasible for early-stage startups.
• Utilization Risk: Without steady workloads, dedicated infrastructure can remain underutilized, wasting valuable resources.
• Expertise Investment: Investing in your own infrastructure necessitates hiring experts to deploy, configure, integrate, and maintain it for you.

Striking the Right Balance

Many AI operations fail to fully assess their current and future needs, leading to poor decisions in computing resource allocation. To navigate this, operations should focus on:

• Workload Analysis: Identify patterns in computing demand (e.g., peak periods for training or inference) to avoid over-provisioning.
• Hybrid Models: Combine on-demand and dedicated infrastructure to balance flexibility and cost-effectiveness. For example, leverage cloud solutions for spikes in demand while relying on owned hardware for routine operations.
• Resource Optimization: Optimize usage with scheduling tools and cost-monitoring platforms to ensure efficient execution of workloads.

2. Performance and Efficiency

Performance and efficiency are at the heart of AI development. From training massive models to running inference at scale, the ability to maximize GPU performance directly impacts an AI operation’s success. However, optimizing for performance isn't just about having the latest GPUs; it's about effectively managing and utilizing resources to meet workload demands while controlling costs.

‍

For the uninitiated, GPUs are utilized in AI development for their parallel processing capabilities. This makes them ideal for:

• Model Training: Speeding up computations for large datasets and deep learning algorithms.
• Inference: Providing low-latency, high-throughput processing for real-time or near-real-time applications.
• Data Preprocessing: Accelerating transformations and feature engineering tasks required for AI workflows.

Earlier, we mentioned the important consideration of configuration and integration in the Buy vs. Build discussion. It has impactful ramifications for the following challenges:

• Underutilization of Resources:
  Misaligned workloads can result in idle GPUs, leading to wasted computational potential and increased costs.
• Overloaded Systems:
  Running too many processes on a single GPU or not allocating sufficient memory can bottleneck performance and reduce efficiency.
• Latency Issues:
  When deploying AI models for inference, especially in real-time applications, high latency can degrade user experience or compromise critical decision-making processes (e.g., in autonomous systems).
• Scalability Bottlenecks:
  As AI models grow in size and complexity, scaling GPU resources to meet these demands often results in diminishing returns if not managed carefully.

Optimization Strategies

• Choosing the Right GPU:
  Different AI workloads require different GPU capabilities. For instance:
  • High-memory GPUs: Essential for training large models with complex architectures.
  • Inference-optimized GPUs: Designed for low-latency, high-throughput applications (e.g., NVIDIA’s A100 or H100 for AI inference).
  • Specialized Chips: Consider TPUs or other accelerators tailored for specific AI workloads.
• Optimizing Parallelism:
  Leverage GPU cores efficiently by breaking tasks into smaller, parallelizable chunks. Techniques like mixed-precision training can also reduce memory requirements and speed up training times without sacrificing accuracy.
• Load Balancing:
  Use distributed computing frameworks (e.g., PyTorch’s DistributedDataParallel or TensorFlow’s MultiWorkerMirroredStrategy) to spread workloads across multiple GPUs or nodes. This prevents bottlenecks and improves throughput.
• Data Pipeline Optimization:
  Streamline data preprocessing to match GPU throughput. Bottlenecks often occur when data isn’t fed to the GPU fast enough, so tools like NVIDIA DALI (Data Loading Library) can accelerate this process.
• Memory Management:
  Optimize GPU memory usage by batching data efficiently and clearing unused memory. Use profilers like NVIDIA Nsight to identify memory bottlenecks and optimize allocations.

Balancing Performance with Cost

Performance optimization doesn’t mean operations should chase the highest-performing GPUs at any cost. Instead, they should focus on striking a balance:

• Spot Instances: Leverage discounted compute options for non-critical training tasks.
• Tiered Workloads: Assign critical workloads to high-performance GPUs while offloading less demanding tasks to lower-cost options.
• Cloud-Based GPU Solutions: Platforms like GMI Cloud offer customizable GPU configurations, enabling operations to scale up or down based on performance needs without the burden of over-investment.

Monitoring and Iterative Improvements

Finally, organizations should have solutions for tracking their performance and efficiency.

• Monitoring:
  Use tools to track GPU utilization, memory use, and processing time. GMI Cloud's Cluster Engine in particular is capable of monitoring everything hardware and software related, ensuring a more robust cluster with reduced downtime.
• Alert systems:
  Prioritize tools with advanced alerting systems that can send notices to the team when a cluster or a project is in danger of failure. As failure can result in catastrophic losses and resource waste, having the right alert system in your monitoring tool can provide blessed savings.
• Iterative Tuning:
  Continuously refine model architectures and training workflows to extract maximum performance. Techniques like hyperparameter tuning and model pruning can significantly improve GPU efficiency.

3. Scaling Considerations

Scalability is another big challenge. As projects grow in complexity and user demands increase, computing infrastructure must evolve to handle larger workloads without compromising on performance or budget. For AI operations relying on GPU resources, scaling effectively can be the difference between accelerating innovation and stalling under unmet demands.

Pinterest is a great example of scaling needs. In 2017 they signed a $750M deal with Amazon Web Services (AWS) to get access to scalable cloud resources and meet the demand of user growth.

‍

We expect the following to be true for the foreseeable future:

• Growing Model Complexity:
  Advances in AI have led to larger and more sophisticated models, such as GPT-style language models and complex vision architectures, which require significantly more computing power.
• Increasing Data Volumes:
  Operations need to process and train on ever-larger datasets to maintain competitive accuracy, further increasing GPU requirements.
• Expanding User Distribution:
  Successful AI products often experience rapid user growth, necessitating scalable infrastructure to meet inference demands in real-time.

So what's any AI operation to do? We're seeing these approaches to scaling computing resources:

Leverage Cloud Solutions:

• Use cloud platforms that provide access to scalable GPU clusters, such as GMI Cloud, AWS, or Google Cloud.
• Cloud providers offer solutions for both short-term bursts and long-term scaling with minimal setup overhead.

Adjustable Scheduling:

• Optimize costs with flexible scheduling to run tasks during non-peak hours. For example, many businesses would see 20-30% cost reductions simply by running offline or automated tasks during hours where GPUs are cheaper and human input isn't necessary.

Reserve Resources in Advance:

• For predictable workloads, reserve GPU resources ahead of time to secure availability and reduce costs.

Use Auto-Scaling Solutions:

• Implement auto-scaling to dynamically adjust compute resources based on workload demands. Kubernetes with GPU support, for instance, can automatically scale pods up or down as needed.

Monitor and Analyze Performance:

• Regularly track resource utilization, bottlenecks, and scaling efficiency using monitoring tools like NVIDIA Nsight or cloud-native dashboards.
• Adjust scaling strategies based on data-driven insights, such as strong monitoring.

4. Data Privacy, Security, and Compliance

And now to talk about something tangentially related to AI operations but critical to operation success: data privacy, security, and compliance. 

Mishandling sensitive data can result in catastrophic consequences: financial penalties, loss of customer trust, or even the collapse of the business. As AI operations rely heavily on data to train and optimize their models, it often includes sensitive information such as personally identifiable information (PII), proprietary business data, or even classified content. Without strong privacy and security measures, AI operations risk:

• Data Breaches: Exposure of sensitive data to malicious actors.
• Intellectual Property Theft: Compromising proprietary algorithms or models that required significant time and investment.
• Regulatory Penalties: Fines for failing to comply with data protection laws like GDPR, CCPA, or HIPAA.

The main challenges for any AI operation are:

Evolving Regulations:
Data protection laws vary by region and are constantly changing. AI companies must ensure compliance with multiple frameworks, such as:

• GDPR (General Data Protection Regulation): Governs data protection for EU citizens.
• CCPA (California Consumer Privacy Act): Regulates data privacy for California residents.
• HIPAA (Health Insurance Portability and Accountability Act): Focused on health-related data.

Data Sovereignty:
Many countries require data to be stored and processed within their borders, complicating infrastructure choices.

Lack of Resources:
Startups often lack dedicated compliance teams, making it harder to keep up with the legal landscape.

Model Theft:
AI models represent valuable intellectual property. If stolen, competitors can reverse-engineer or misuse them, erasing competitive advantages.

Insider Threats:
Employees or contractors with access to sensitive data or models can inadvertently—or intentionally—compromise security.

Cloud Vulnerabilities:
Many companies use cloud-based platforms for compute and storage. Misconfigured access controls or unpatched vulnerabilities can leave data exposed.

Strategies for Ensuring Privacy, Security, and Compliance

The following are common methods for companies to ensure mitigate the identified challenges:

• Data Encryption:
  • Encrypt sensitive data at rest and in transit using industry standards like AES-256.
  • Utilize end-to-end encryption for communication between systems.
• Access Controls and Audits:
  • Implement role-based access controls (RBAC) to ensure that only authorized personnel can access sensitive resources.
  • Regularly audit access logs to detect anomalies or unauthorized access attempts.
• Model Protection:
  • Use techniques like differential privacy to obscure sensitive data during training.
  • Employ model watermarking or fingerprinting to identify and track intellectual property theft.
• Secure Development Practices:
  • Adopt DevSecOps principles to integrate security into every phase of the development lifecycle.
  • Conduct regular vulnerability assessments and penetration tests on applications and infrastructure.
• Compliance-Centric Infrastructure:
  • Choose compute providers that prioritize compliance. Look for certifications such as ISO 27001, SOC 2, and HIPAA compliance.
  • Partner with cloud platforms offering region-specific data centers to meet data sovereignty requirements.
• Privacy-First Design:
  • Build systems with user privacy as a core principle, minimizing data collection and ensuring anonymization whenever possible.
  • Provide transparency about how data is used and allow users to opt out of data collection where feasible.
