OpenStack vs. Kubernetes: Building Resilient Cloud Infrastructure


Table of Contents

In cloud computing, two platforms stand out: OpenStack and Kubernetes. OpenStack, an infrastructure-as-a-service (IaaS) platform, enables the creation and management of virtualized data centers that cater to diverse workloads. Kubernetes, a container orchestration platform, excels at managing large-scale, distributed applications, facilitating rapid deployment and scaling.

The OpenStack vs. Kubernetes debate often centers on which is superior, but both platforms possess unique strengths and serve different needs. The decision to adopt either, or both, depends on factors like organizational goals, infrastructure, and application requirements.

Given the frequency of cyber threats, organizations need to ensure that their data and applications are fortified against unexpected events. In this article, we dive deep into OpenStack and Kubernetes, uncovering their differences, strengths, weaknesses, and ideal use cases. We also discuss the vital role of data protection in maintaining business continuity and how to build a resilient cloud infrastructure that addresses modern challenges.

A Head-to-Head Comparison of OpenStack and Kubernetes

OpenStack and Kubernetes, while both designed for cloud infrastructure management, have distinct architectures and approaches.

OpenStack is a sprawling collection of projects that collectively implement a comprehensive IaaS platform. It uses virtual machines (VMs) as its fundamental building blocks. VMs emulate entire operating systems, providing complete isolation, which makes them ideal for running traditional applications that require dedicated resources. OpenStack’s modular architecture offers a wide array of services, including compute, storage, networking, and identity management, enabling organizations to build private or public clouds tailored to their specific needs.

Kubernetes, on the other hand, is a container orchestration platform. Containers are lightweight, portable units of software that package an application and its dependencies together. Unlike VMs, containers share the host operating system’s kernel, making them more efficient and faster to start. Kubernetes manages the deployment, scaling, and networking of containers, automating many of the complex tasks involved in running containerized applications.

Each platform brings unique strengths to the table. OpenStack’s mature ecosystem and extensive feature set make it a compelling choice for organizations seeking a comprehensive IaaS platform with granular control over their infrastructure. Kubernetes’ agility and scalability are particularly well-suited for cloud-native applications that need to adapt quickly to changing demands.

However, both platforms also have their limitations. OpenStack’s complexity can be daunting, requiring specialized expertise to manage and maintain. Kubernetes, while powerful, can have a steep learning curve and may not be the best fit for all applications.

The table below summarizes the key feature differences between OpenStack and Kubernetes.







Core Strengths

Comprehensive IaaS platform with an extensive feature set

Agility, scalability, and automation for managing containerized applications

Ideal Use Cases

Traditional applications, complex workloads, environments requiring granular control

Cloud-native applications, microservices architectures, rapid scaling situations


Complexity, steep learning curve

Potential overhead for simpler applications, less mature ecosystem than OpenStack

The Recovery Imperative: Why Resilience Matters

Data is the lifeblood of organizations, so the importance of resilience cannot be overstated. Cyber threats, natural disasters, hardware failures, and human errors pose constant risks to business continuity. The potential consequences of data loss or downtime can be devastating, including financial losses, reputational damage, and even legal ramifications.

Ransomware, in particular, targets organizations of all sizes and industries. A successful ransomware attack can encrypt critical data, rendering it inaccessible and holding it hostage until a ransom is paid. The average cost of recovering from a ransomware attack is estimated to be in the millions of dollars, not to mention the intangible costs of lost productivity and customer trust.

To mitigate these risks, organizations need a robust ransomware recovery plan that includes comprehensive backup and disaster recovery (DR) solutions. A well-designed recovery plan ensures that your critical data and applications can be restored quickly and efficiently in the event of a disruption, whether you’re running OpenStack or Kubernetes.

In the context of the Kubernetes vs. OpenStack debate, data protection takes on added significance. OpenStack’s distributed architecture and Kubernetes’ dynamic nature introduce unique challenges when it comes to protecting your data and applications. Trilio’s application-aware data protection solutions are designed to address these challenges, ensuring that your cloud infrastructure remains resilient even in the face of adversity. By automating backup and recovery processes, Trilio helps you minimize downtime, protect your data, and safeguard your organization’s future, whether you’ve chosen OpenStack or Kubernetes for your cloud infrastructure.

Recovery Considerations

Both OpenStack and Kubernetes offer native mechanisms for data and application recovery. OpenStack’s Cinder component provides volume snapshots for persistent storage, while Kubernetes uses ReplicationControllers and StatefulSets to manage pod replicas. However, these built-in tools often fall short when dealing with complex, real-world recovery scenarios.

Recovery capabilities are a critical OpenStack vs. Kubernetes differentiator. OpenStack’s snapshots, while useful, might not capture the entire application state, leading to inconsistencies during recovery. Kubernetes replication mechanisms offer limited protection against data corruption or accidental deletion.

Additionally, neither platform offers comprehensive protection against ransomware attacks, which can encrypt data across multiple volumes or containers, rendering traditional recovery methods ineffective. In the face of such threats, a more robust, application-aware backup and recovery solution is essential.

Trilio overcomes the recovery limitations of both OpenStack and Kubernetes by offering agentless, application-consistent backups and granular recovery options that seamlessly integrate with both platforms. This ensures complete protection for your entire cloud environment, whether you’ve chosen OpenStack, Kubernetes, or a combination. 

With Trilio, you can easily back up and restore entire applications, ensuring the complete and consistent recovery that is crucial for maintaining business continuity and minimizing downtime in the face of any disaster.

Factors for Choosing the Right Platform

There’s no one-size-fits-all answer to the question of whether to adopt OpenStack, use Kubernetes, or take a hybrid approach. The ideal choice depends on a multitude of factors specific to your organization’s needs and goals:

  • Workloads: Consider your workload types. Are you primarily dealing with monolithic applications that would benefit from OpenStack’s VM-based isolation, or are you focused on microservices and cloud-native applications that thrive in the containerized environment of Kubernetes?
  • Existing Infrastructure and Skillsets: Evaluate your current infrastructure and the expertise of your IT team. If you have a significant investment in legacy systems and a team well-versed in virtualization technologies, OpenStack might be a good choice. Conversely, if you’re embracing a DevOps culture and have experience with containerization, Kubernetes could be a natural fit.
  • Scalability and Flexibility: Assess your scalability requirements. Kubernetes excels at horizontal scaling, making it ideal for applications with fluctuating workloads. OpenStack, while scalable, might require more manual intervention to adjust resources.
  • Recovery Requirements and Risk Tolerance: As we’ve discussed, data protection and disaster recovery are essential considerations. If your organization has stringent recovery requirements and a low tolerance for downtime, it’s crucial to choose a platform that can be easily integrated with robust backup and recovery solutions, like Trilio.
  • Community and Support: Both OpenStack and Kubernetes boast vibrant communities and extensive documentation. However, the level of support and resources available can vary. Consider the maturity of each platform’s ecosystem and the availability of third-party tools and services.
