PAI-EAS can also be more cost-effective than managing the entire stack
yourself.
How to Access and Deploy DeepSeek on Alibaba Cloud
There are primarily two approaches to using DeepSeek models
on Alibaba Cloud, catering to different needs and technical expertise:
Method 1: Using Platform for AI - Elastic Algorithm
Service (PAI-EAS) (Recommended)
Fig 1: Configuring a DeepSeek model deployment on
PAI-EAS
PAI-EAS is Alibaba Cloud's managed service for deploying AI
models as online prediction services. This is often the easiest and most
efficient way to get started.
-
Concept:
You select a DeepSeek model (either a pre-built image provided by Alibaba
Cloud/partners if available, or by packaging the open-source model
yourself into a compatible format) and deploy it using PAI-EAS. The
service handles the underlying infrastructure, scaling, and provides you
with an API endpoint.
-
Steps
(High-Level):
-
Prepare
the Model: Obtain the desired DeepSeek model weights (e.g., from
Hugging Face or the official DeepSeek source). You might need to package
this into a container image along with the necessary inference code
(e.g., using libraries like transformers, vLLM, or Triton Inference
Server). Alibaba Cloud often provides base images or examples to simplify
this. Check the PAI documentation or ModelScope (Alibaba's model
community) for potential pre-packaged DeepSeek options.
-
Navigate
to PAI Console: Log in to your Alibaba Cloud account and go to the
Platform for AI console.
-
Select
PAI-EAS: Choose the Elastic Algorithm Service for deployment.
-
Configure
Deployment: Create a new service, specifying:
- The
model source (e.g., pointing to your container image registry).
- The
required resources (CPU, memory, GPU type and count – crucial for LLMs).
- Scaling
parameters (minimum/maximum instances).
Deploy:
Initiate the deployment process. PAI-EAS will pull the image, provision
resources, and set up the endpoint.
Access
the Endpoint: Once deployed, PAI-EAS provides an invocation URL and
authentication details (like an API token). You can then send requests
(e.g., prompts) to this endpoint via HTTP POST requests using tools like curl
or SDKs in Python, Java, etc.
Pros:
Managed infrastructure, auto-scaling, simplified deployment, integration
with monitoring and logging.
Cons:
Less control over the underlying environment compared to self-hosting;
potentially reliant on available pre-built images or requires
containerization effort.
Method 2: Self-Hosting on Elastic Compute Service (ECS)
or Container Service (ACK)
Fig 2: Selecting a GPU-accelerated instance type
For users needing maximum control or having specific custom
environment requirements, you can host the DeepSeek model directly on virtual
machines or Kubernetes clusters.
-
Concept:
You provision virtual machines (ECS instances, likely with GPUs) or set up
a Kubernetes cluster (ACK). You then manually install the necessary
dependencies (Python, CUDA, AI libraries), download the DeepSeek model
weights, and run an inference server (like a Flask/FastAPI app wrapping
the model, or using frameworks like vLLM or TGI).
-
Steps
(High-Level):
-
Provision
Compute Resources: Create ECS instances (choose appropriate GPU types
like NVIDIA A10, V100, A100) or set up an ACK cluster.
-
Set
up Environment: Install OS, drivers (NVIDIA drivers, CUDA), Python
environments, and required libraries (transformers, torch, vllm, etc.).
-
Download
Model: Fetch the desired DeepSeek model weights.
-
Develop/Deploy
Inference Server: Write or configure an application that loads the
model and exposes an API endpoint for receiving prompts and returning
generations.
-
Manage
and Scale: You are responsible for monitoring, security patching,
load balancing, and scaling the setup manually or using Kubernetes
features.
Pros:
Full control over the environment, software stack, and configuration.
Cons:
Significantly higher operational overhead, requires expertise in
infrastructure management, responsible for manual scaling and high
availability.
Getting Started: A Conceptual Example (using PAI-EAS)
Imagine you've deployed a DeepSeek model via PAI-EAS. You'd
receive an endpoint URL and an authorization token. Making a request might look
conceptually using Python's requests library.
