Automating Cloud Deployments With Heat Stacks on Rumble Cloud

Jun 18, 2024 - 4 min read

Efficiently managing and deploying cloud infrastructure is critical for modern businesses. OpenStack Heat, the orchestration service that powers Rumble Cloud Automation service, simplifies these processes by enabling infrastructure as code. Heat stacks enable you to define and manage your cloud resources using templates. Rumble Cloud leverages Heat stacks to automate various cloud usage scenarios, providing a streamlined experience for deploying and managing applications.

Introduction to Rumble Cloud Automation Service

Heat integrates seamlessly with various Rumble Cloud services to provision and manage resources. For example, it interacts with Compute service to create and manage compute instances, Network service to set up networking components such as subnets and routers, and Storage service for block and object storage. By defining these components in a Heat template, you can ensure that all resources are correctly configured and interlinked, resulting in a cohesive and automated infrastructure deployment.

Benefits of Using Heat stacks:

  • Automate the deployment and management of cloud resources
  • Ensure consistent configurations across multiple environments
  • Easily scale resources up or down based on demand
  • Reuse templates to deploy identical environments quickly

Deploying Web Hosting and Development Environments

Deploying web hosting solutions, such as WordPress with a MySQL database, can be seamlessly automated using Heat stacks. This setup is ideal for configurations starting with 2 vCPUs, providing sufficient resources for small to medium-sized web hosting needs. Heat templates can define the necessary compute, networking, and storage resources, ensuring they are correctly integrated.

For development environments, consistent and repeatable setups are crucial. A Heat stack can automate the deployment of development servers, ensuring each instance is configured identically. This automation reduces setup time and eliminates configuration drift, making it easier to manage multiple development environments.

Medium-sized Applications and Databases

Medium-sized applications, such as e-commerce platforms, require more resources. With configurations around 4 vCPUs, you can efficiently handle higher traffic and more complex transactions. Heat stacks can automate the deployment of web servers, application servers, and databases, ensuring all components are correctly configured and integrated. This automation not only simplifies the initial deployment but also makes scaling the infrastructure straightforward as your application grows.

Virtual desktops for remote workers are another use case for this configuration. Heat stacks can automate the setup of virtual desktop infrastructure (VDI), providing a consistent and scalable solution for remote workforces.

Large-scale Applications and Services

For large-scale applications and services, such as high-traffic websites and enterprise-grade applications, configurations with 8 vCPUs or more are necessary. Heat stacks can automate the deployment of load balancers, web servers, and databases, ensuring scalability and performance. By defining these resources in a Heat template, you can ensure that all components are correctly integrated and can scale efficiently as demand increases.

Machine learning and AI workloads also benefit from these configurations. Heat stacks can automate the deployment of environments necessary for model training and inference, utilizing frameworks like TensorFlow and PyTorch. This automation accelerates AI development and deployment, enabling faster iteration and innovation.

Advanced Computational Tasks

For advanced computational tasks such as scientific simulations and big data analytics, configurations with more than 8 vCPUs provide the necessary computational power. Heat stacks can automate the setup of powerful compute nodes and storage systems, ensuring that the infrastructure is optimized for high-performance tasks. This automation ensures consistency and reduces the complexity of managing large-scale computational workloads.

Enterprise applications, which require high availability and performance, can also be efficiently deployed using Heat stacks. By automating the deployment of application servers and databases, you can ensure that these applications are always available and can handle increased load without manual intervention.

Example Heat Template

To illustrate the power of Heat stacks, here is an example Heat template that deploys a simple web server. This template demonstrates the basic structure of a Heat template, defining a compute instance, a floating IP, and the association between them. The user data section includes a script to install and start the Apache web server, demonstrating how you can automate post-deployment configuration.

Example Heat template:

heat_template_version: 2018-08-31
description: >
  Simple template to deploy a web server
    type: OS::Nova::Server
      flavor: m2a.xlarge
      image: Ubuntu 20.0
      key_name: my_key
        - network: private
      user_data: |
        apt-get update
        apt-get install -y apache2
        systemctl enable apache2
        systemctl start apache2
    type: OS::Neutron::FloatingIP
      floating_network: public
    type: OS::Neutron::FloatingIPAssociation
      floatingip_id: { get_resource: my_floating_ip }
      port_id: { get_attr: [my_instance, first_address] }
