How we deployed a datacenter using Openstack

“How we deployed a datacenter using OpenStack:”

Learn how we implemented a scalable, high-availability cloud infrastructure with self-service provisioning, automation, and seamless billing integration to meet business IT demands.”

Project Objective

The primary objective was to implement a comprehensive OpenStack solution for a hosting company, enabling them to deliver public cloud as a service. The solution needed to be capable of scaling efficiently and meeting the dynamic needs of customers. It also required ensuring high availability, automation, and a seamless integration with billing and operational systems. Implement an OpenStack solution for a hosting company to enable them to provide public cloud as a service and designed for scaling.

Customer Requirements

The customer was looking to achieve the following with the deployment.

  1. Offer customer self-service and fully automated provisioning through Horizon.
  2. Seamless integration to billing software.
  3. Deploy OpenStack with High Availability.
  4. Multi-tenancy integrated with Keystone.
  5. Integration with automation tools (Puppet, Ansible, Heat).
  6. Build a robust, scalable, agile infrastructure that can support the IT demands.
  7. Avoid any kind of vendor lock.

Challenges with Existing Solutions:

Challenges with Existing Solutions

Before deploying OpenStack, the hosting company faced several limitations with their legacy infrastructure:

  1. Rigid Hardware and Bare Metal Servers: The use of traditional bare metal servers made scaling and resource allocation time-consuming. This lack of flexibility created challenges in meeting customer demand quickly.
  2. Limited Virtualization Features: Their previous virtualization setup lacked advanced features such as dynamic resource scaling and high availability. This limitation was a bottleneck, preventing them from delivering reliable cloud services.
  3. Capacity Expansion Delays: The company faced delays in expanding their infrastructure to accommodate growth. Scaling their services on-demand was not possible, which hindered their ability to meet business demands promptly.

Architecture:

process architecture

The OpenStack architecture was designed to provide a robust, flexible, and scalable solution:

  1. High Availability: We ensured high availability by configuring redundant nodes and clusters for all critical OpenStack services, including Nova (compute), Cinder (block storage), and Neutron (networking). This architecture enabled the system to remain operational even in the event of hardware or service failures.
  2. Self-Service Portal: We implemented Horizon, the OpenStack dashboard, which allowed customers to provision and manage their own virtual machines, storage, and networking resources. This self-service model reduced the need for manual intervention, making it easier for customers to scale their resources as needed.
  3. Multi-Tenancy via Keystone: The deployment leveraged Keystone for identity and access management. This ensured that each customer’s data and cloud resources were securely isolated from others, meeting the security and privacy requirements of multi-tenant cloud environments.
  4. Automation Tools Integration: By integrating Puppet, Ansible, and Heat, we were able to automate the configuration management, provisioning, and orchestration of the OpenStack components. This enabled faster, more efficient deployments and minimized human error.
  5. Scalable Infrastructure: The deployment leveraged OpenStack’s flexible architecture to allow seamless scaling of resources. Whether the customer needed more compute capacity, storage, or networking, OpenStack’s distributed architecture allowed for easy scaling.

Results:

  1. Leveraging the self-service portal, clients are now able to adjust capacity (resources) on the fly
  2. We were able to free up expensive resources enabling the deployment to focus on delivering added business value. 
  3. Cloud enablement lets users provision what they need and when they need it.
  4. Implemented integrated application monitoring for faster troubleshooting
  5. Accelerated OpenStack adoption.

Conclusion

The OpenStack deployment was a success, delivering a highly scalable, flexible, and reliable cloud infrastructure that met the hosting company’s requirements for high availability, automation, and seamless billing integration. By leveraging OpenStack’s open-source, vendor-agnostic nature, the company was able to avoid vendor lock-in while providing their customers with a self-service platform that could be easily scaled as demand grew. This deployment not only addressed the company’s immediate IT challenges but also positioned them for future growth in the competitive cloud services market.
