From image and speech recognition to complex predictions and personalised recommendations, machine learning models are delivering incredible value. However, training these deep neural network models requires immense computational power, often needing weeks on specialised hardware. For example, the BERT language model has over 110 million parameters, requiring a massive training dataset to train all 110 million parameters to optimal values. Each epoch requires billions of weight update operations.
Traditional CPUs are ill-equipped to train such LLM on massive datasets. So, organisations are opting for Cloud GPUs to tackle complex models through their parallel processing capabilities in days instead of weeks or months. To give you an idea, the GPU market is estimated to be valued at USD 70.9 billion in 2024. So, we expect the market to reach USD 1,159.3 billion by 2034, developing at a CAGR of 32.2%. This increasing number demonstrates the need for powerful Cloud GPUs for highly-intensive tasks as organisations continue to use machine learning extensively.
What are Cloud GPUs?
Cloud computing has revolutionised how organisations access computing resources, allowing convenient and flexible on-demand provisioning of servers, storage, databases, and other services over the internet. Clouds extend these same benefits to advanced graphics processing units (GPUs). Instead of needing to purchase and maintain high-end GPU hardware on local servers, cloud GPUs allow using GPU resources hosted in the provider's data centres and accessed remotely.
For machine learning workloads, cloud GPUs grant easy access to unprecedented parallel processing power without any local hardware investment. By leveraging cloud GPU virtual machines, organisations can instantly tap into many GPU cores and teraflops of capacity. Cloud GPU's on-demand scalability supports seamlessly adjusting resources to your application needs.
Benefits of Using Cloud GPUs for Machine Learning
Leveraging the massive parallel processing power of cloud GPUs offers game-changing advantages for machine learning, including:
Faster Training
Using Cloud GPUs for machine learning significantly accelerates training times compared to traditional CPUs, particularly in deep learning models. This enhancement is primarily due to the architecture of GPUs, which are designed to handle parallel tasks efficiently. While a CPU may have a higher clock speed for individual tasks, a GPU contains thousands of smaller, more efficient cores designed for handling multiple tasks simultaneously. This makes GPUs exceptionally well-suited for the matrix and vector operations that are fundamental in machine learning algorithms.
Deep learning models, which often involve complex neural networks, benefit immensely from this parallel processing capability. Training these models involves processing vast amounts of data and performing numerous calculations. On a CPU, this process can be time-consuming, leading to bottlenecks in model development and deployment. Cloud GPUs, on the other hand, can perform these operations much faster, reducing training times from weeks or days to hours or even minutes. This speed enhancement not only accelerates the iterative process of model development but also enables the exploration of more complex models and techniques, which would be impractical with slower processing speeds.
Larger Models
Cloud GPUs empower machine learning practitioners to train larger and more complex models, which may have billions of parameters. The increased processing power of GPUs allows for the handling of these extensive computations more efficiently than CPUs. This capability is crucial for advancing in fields like natural language processing and computer vision, where large models have shown superior performance.
The enhanced memory bandwidth and greater computational abilities of GPUs enable the processing of larger datasets and the implementation of more sophisticated algorithms. This allows for deeper neural networks with more layers, which can capture intricate patterns and nuances in data. In practical terms, this means models can achieve higher accuracy and better generalisation of complex tasks.
The availability of high-performance GPUs in the cloud means that researchers and developers can access state-of-the-art resources without the prohibitive costs of owning and maintaining such hardware. This democratises access to advanced machine-learning capabilities, enabling a wider range of organisations and individuals to participate in cutting-edge research and development.
Reduced Costs
Utilising cloud GPUs for machine learning can offer significant cost savings compared to investing in and maintaining on-premises GPU hardware. One primary advantage is the elimination of upfront capital expenditures. Acquiring high-end GPU servers can be prohibitively expensive, especially for small to medium-sized organisations or individual practitioners. Cloud-based services operate on a pay-as-you-go model, allowing users to access advanced computing resources without a large initial investment.
The cost of maintaining and upgrading hardware is also a concern with on-premises solutions. In contrast, cloud providers manage maintenance, and upgrades, and ensure that the hardware is running optimally, reducing the burden on the user. This also means that users can always access the latest GPU technology without additional investment.
Cloud GPUs offer cost efficiency through scalability. Users can adjust their resource usage based on current needs, ensuring they only pay for what they use. This is particularly beneficial for projects with variable computational requirements, such as those common in machine learning, where resource needs may fluctuate throughout the project.
Scalability and Flexibility
Cloud GPUs provide unparalleled scalability and flexibility, which are critical in the dynamic field of machine learning. Scalability refers to the ability to easily and quickly adjust computing resources to meet the needs of a project. In a cloud environment, resources can be scaled up to accommodate large-scale training sessions or high-demand periods, and scaled-down when less computational power is needed, ensuring efficient use of resources and cost-effectiveness.
This flexibility extends beyond the mere scaling of resources. Cloud platforms often provide a wide range of GPU options, allowing users to select the most appropriate hardware for their specific project requirements. Whether the need is for higher memory, faster processing, or energy efficiency, there is usually a suitable option available in the cloud.
The cloud environment also supports the use of various tools and frameworks for machine learning. Users can choose their preferred programming languages, libraries, and frameworks, which can significantly streamline the development process. This flexibility is particularly beneficial for teams working on complex projects that may require a combination of different tools and technologies.
Accessibility and Collaboration
Cloud GPUs enhance accessibility and collaboration for teams working on machine learning projects. With cloud-based resources, team members can access the same high-performance computing environment from anywhere in the world, as long as they have an internet connection. This accessibility is particularly beneficial for distributed teams or for individuals who are working remotely.
Collaboration is further facilitated by the centralised nature of cloud resources. Teams can share datasets, models, and tools within the same cloud environment, ensuring that everyone is working with the same information and reducing the risk of inconsistencies or errors that can occur with local setups. This shared environment also makes it easier to manage version control and track changes in collaborative projects.
Cloud platforms often come with built-in tools for monitoring, managing, and optimising machine learning workflows. These tools can be accessed by multiple team members, allowing for a collaborative approach to managing resources, debugging
