IBM Cloud Virtual Servers

Overview

IBM Cloud Virtual Servers offer Infrastructure as a Service (IaaS) capabilities, enabling users to provision and manage virtual machines on demand. The service is designed to support a range of use cases, from general-purpose applications to demanding enterprise workloads and hybrid cloud strategies. IBM Cloud provides two primary offerings: Virtual Servers for VPC (Virtual Private Cloud) and Classic Virtual Servers (public and dedicated options), catering to different architectural requirements and levels of isolation. IBM Cloud Virtual Servers documentation outlines these distinctions and deployment models.

Virtual Servers for VPC are built on a modern network architecture, providing a logically isolated network that users can define and control. This design supports enhanced security and flexibility for deploying applications within a private cloud-like environment on IBM's public infrastructure. It is suitable for new applications, microservices, and containerized workloads that benefit from a software-defined network. Conversely, Classic Virtual Servers provide compute instances within IBM's traditional data center infrastructure, offering public and dedicated options. Dedicated classic servers provide single-tenant hardware, which can be advantageous for workloads with strict compliance or performance requirements, as described in IBM Cloud's Classic Virtual Servers overview.

The platform supports various operating systems, including multiple Linux distributions and Windows Server, allowing organizations to migrate existing applications or deploy new ones using familiar environments. IBM Cloud Virtual Servers are often chosen by enterprises leveraging other IBM Cloud services, such as databases, AI/ML platforms, and blockchain solutions, due to the integrated ecosystem. This integration streamlines development and operations for complex, distributed applications. The service's global availability, with data centers in numerous regions, enables businesses to deploy applications closer to end-users for reduced latency and to meet data residency requirements.

Key use cases for IBM Cloud Virtual Servers include hosting web applications, running development and test environments, supporting enterprise resource planning (ERP) systems, and serving as compute resources for analytics and big data processing. For organizations focused on hybrid cloud, IBM Cloud's offerings facilitate extending on-premises infrastructure to the cloud with consistent tooling and management. This approach allows for workload portability and flexible scaling, addressing common challenges in modern IT environments. A detailed discussion on hybrid cloud strategies and their benefits can be found in resources like Martin Fowler's article on Hybrid Cloud Patterns, highlighting the architectural considerations that IBM Cloud aims to support.

Getting started

To provision an IBM Cloud Virtual Server for VPC using the IBM Cloud API, you can use curl to interact with the API endpoints. This example demonstrates creating a basic virtual server instance. Replace placeholder values with your specific configuration, including your IAM token and VPC details. Ensure you have an IBM Cloud account, a Virtual Private Cloud (VPC), and an SSH key configured in your account. The full API reference is available on the IBM Cloud API Docs for Virtual Servers.

# 1. Obtain an IAM token
API_KEY="YOUR_IBM_CLOUD_API_KEY"
IAM_TOKEN=$(curl -s -X POST \
  "https://iam.cloud.ibm.com/identity/token" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "grant_type=urn:ibm:params:oauth:grant-type:apikey&apikey=${API_KEY}" \
  | jq -r .access_token)

# 2. Define your instance parameters
VPC_ID="YOUR_VPC_ID" # e.g., r006-a889b78e-6c0b-47e2-a0b8-2a7e78d9b139
ZONE_NAME="us-south-1" # e.g., us-south-1, eu-de-1
IMAGE_ID="YOUR_IMAGE_ID" # e.g., r006-69a4ad2c-bb9b-4475-b924-d2427a20c58e (Ubuntu 20.04)
PROFILE_NAME="cx2-2x4" # e.g., cx2-2x4 (2 vCPU, 4GB RAM)
SSH_KEY_ID="YOUR_SSH_KEY_ID" # e.g., r006-a889b78e-6c0b-47e2-a0b8-2a7e78d9b139
SUBNET_ID="YOUR_SUBNET_ID" # e.g., r006-a889b78e-6c0b-47e2-a0b8-2a7e78d9b139

# 3. Create the Virtual Server instance
curl -X POST \
  "https://{region}.vpc.cloud.ibm.com/v1/instances?version=2020-04-10&generation=2" \
  -H "Authorization: Bearer ${IAM_TOKEN}" \
  -H "Content-Type: application/json" \
  -d "{
    \"name\": \"my-test-instance\",
    \"vpc\": {\"id\": \"${VPC_ID}\"},
    \"zone\": {\"name\": \"${ZONE_NAME}\"},
    \"image\": {\"id\": \"${IMAGE_ID}\"},
    \"profile\": {\"name\": \"${PROFILE_NAME}\"},
    \"keys\": [{\"id\": \"${SSH_KEY_ID}\" stark }]
  }"

For Python, you can use the ibm-cloud-sdk-core along with the specific IBM Cloud services SDKs. First, install the SDKs:

pip install ibm-cloud-sdk-core ibm-vpc-sdk

Then, use the following Python code to create a similar instance. Ensure you have configured your environment with IBMCLOUD_API_KEY and other necessary credentials.

import os
from ibm_vpc.vpc_v1 import VpcV1
from ibm_cloud_sdk_core.authenticators import IAMAuthenticator

# Replace with your actual API Key and service URL
api_key = os.getenv("IBMCLOUD_API_KEY", "YOUR_IBM_CLOUD_API_KEY")
service_url = os.getenv("VPC_API_ENDPOINT", "https://us-south.vpc.cloud.ibm.com/v1")

# Authenticate
authenticator = IAMAuthenticator(api_key)
vpc_service = VpcV1(authenticator=authenticator)
vpc_service.set_service_url(service_url)

# Define instance parameters
vpc_id = "YOUR_VPC_ID"
zone_name = "us-south-1"
image_id = "YOUR_IMAGE_ID"
profile_name = "cx2-2x4"
ssh_key_id = "YOUR_SSH_KEY_ID"
subnet_id = "YOUR_SUBNET_ID"

try:
    instance_prototype = {
        "name": "my-python-instance",
        "vpc": {"id": vpc_id},
        "zone": {"name": zone_name},
        "image": {"id": image_id},
        "profile": {"name": profile_name},
        "keys": [{"id": ssh_key_id}],
        "primary_network_interface": {"subnet": {"id": subnet_id}}
    }
    
    instance = vpc_service.create_instance(instance_prototype=instance_prototype).get_result()
    print(f"Successfully created instance: {instance['name']} with ID: {instance['id']}")
except ApiException as e:
    print(f"Error creating instance: {e.code} - {e.message}")
