Multi Tenancy in Private Cloud

In this post, we explore why multi-tenancy in your cloud platform is crucial for modern cloud operations by examining an example of a financial services company navigating common challenges in private cloud management. We highlight how the lack of multi-tenancy contributes to why development teams often advocate for public cloud.

To illustrate, consider a large financial services company that operates its entire infrastructure on a private cloud, retaining ownership of its hardware to maximize control over data, performance, and compliance. Spread across multiple data centers in the Netherlands, they run private Kubernetes clusters with extensive automation and maintain a robust internal network. Despite this sophisticated setup, their development, compliance, security, and IT operations teams face a common frustration.

Whenever a new staging environment is needed or a virtual machine must be provisioned, teams must request resources through a central platform team. This process, intended to provide control, instead becomes a bottleneck. Filling out forms, specifying configurations, and waiting in a queue for approvals can stretch what should be a quick task into days or even weeks.

The platform team is overwhelmed by these requests. To alleviate the strain, the company has built custom provisioning tools. However, these tools are fragile, require frequent maintenance, and struggle to adapt to evolving business needs. The result? Innovation slows, productivity takes a hit, and the allure of the public cloud’s agility becomes harder to ignore.

The Limitations of Traditional Private Cloud Solutions

Many legacy private cloud platforms weren’t designed with true multi-tenancy in mind. Instead of empowering teams to self-manage their resources, these systems funnel provisioning requests through a centralized gatekeeper. This outdated approach leads to several operational pain points:

1. Manual processes: Provisioning resources often requires multiple layers of approval and manual configuration.
2. Lack of autonomy: Teams cannot spin up virtual machines, create Kubernetes clusters, or manage networking without submitting a ticket and waiting for approval.
3. Operational burden: Platform teams are overloaded with requests, preventing them from focusing on strategic improvements to the infrastructure.

In response, organizations often create custom provisioning tools to close the gap. However, these tools introduce their own challenges: they’re costly to develop and maintain, prone to breaking under new requirements, and inflexible in the face of future needs.

How Thalassa Cloud Transforms Multi-Tenancy

Thalassa Cloud is designed to eliminate these pain points by enabling multi-tenancy from the ground up. Instead of treating resource provisioning as a centralized bottleneck, our platform introduces organizations—dedicated, isolated environments within your private cloud infrastructure for different teams, departments, or service providers.

Here’s how organisations in Thalassa Cloud change the game:

1. Resource Isolation: Each organisation is allocated its own resource quotas, including virtual machines, Kubernetes clusters, VPCs, and load balancers. Teams can operate independently without interfering with one another’s environments.
2. Self-Service Provisioning: Teams can provision their own infrastructure directly—whether it’s a Kubernetes cluster for development or a virtual machine for testing. There’s no need to go through a central support team.
3. Access Controls: Role-based access control (RBAC) allows administrators to define exactly what each team can access and manage within their organisation.
4. Built-in Governance: Quotas prevent resource overuse while ensuring that teams stay within the boundaries set by the platform. This ensures compliance without slowing down workflows.

A Real-World Example: Simplifying Complex IT Operations

Consider a financial institution with multiple IT service providers managing its infrastructure:

• One provider handles virtual machines for compliance testing.
• Another manages Kubernetes clusters for application development.
• A third oversees network configurations, such as VPCs and load balancers.

In a traditional private cloud setup, all of these providers and teams would be forced to submit support tickets for their infrastructure needs. The platform team would act as the middleman, manually provisioning resources based on each request.

With Thalassa Cloud, the story is different:

• Each service provider is assigned its own organisation with dedicated quotas.
• Teams within these organisations can self-serve their infrastructure, spinning up the resources they need within seconds.
• Access permissions and quotas ensure that each provider only sees and manages its own environment.

As a result, the platform team no longer has to manage every request, and the IT teams and developers can deliver services faster, with greater autonomy and security.

Why This Matters for Private Cloud

Legacy private cloud solutions that lack true multi-tenancy create operational roadblocks, especially for industries with strict compliance and data isolation requirements. By enabling self-service provisioning and resource isolation, Thalassa Cloud empowers organizations to:

• Increase Agility: Teams can provision resources on-demand, speeding up development and operations.
• Reduce Operational Overhead: Platform teams are freed from repetitive provisioning tasks, allowing them to focus on innovation.
• Ensure Security and Compliance: With granular access controls and resource quotas, organisations can enforce governance while empowering their teams.

Unlocking the Potential of Your Private Cloud

Thalassa Cloud was built to bring the flexibility and speed of public cloud services to private infrastructure. We recognize that enterprises need more than hardware—they need a platform that makes multi-tenancy seamless and secure. By embedding support for organizations at the core, Thalassa Cloud enables teams to deliver value without waiting for infrastructure bottlenecks to clear.

One of the primary reasons development teams and IT leaders are drawn to the public cloud is its self-service capabilities and automation, which reduce operational overhead. However, public cloud solutions often come with trade-offs: reduced control, data sovereignty concerns, and unpredictable costs.

Our mission is to bring the self-service simplicity of the public cloud to infrastructure that you own and control. By empowering you to manage both the physical and virtual IT stack, Thalassa Cloud provides the agility of the public cloud while maintaining full control over your data, costs, and compliance. With Thalassa Cloud, your teams can innovate faster without sacrificing security, governance, or financial predictability.
