Key Differences between VMware and OpenStack

When comparing VMware and OpenStack, the two platforms differ in terms of architecture, deployment, management, scalability, and flexibility. Each caters to different organizations, workloads, and IT strategies. Below is a breakdown of the major differences between them.

Architecture

VMware products are tightly integrated and controlled within its ecosystem. The architecture is designed for ease of use, and organizations rely on VMware to handle the majority of backend operations, ensuring high performance and reliability.

OpenStack, on the other hand, has a modular architecture consisting of multiple components (e.g., Nova for compute, Neutron for networking, Cinder for storage) that can be used independently or together to create cloud environments. OpenStack is not tied to any single vendor and allows users to customize and modify the architecture as needed.

Deployment and Management

VMware is known for its user-friendly deployment process and centralized management through vCenter, which offers a GUI-based interface for controlling and monitoring virtual environments. Deployment is typically simpler and faster with VMware due to its pre-integrated components. VMware also provides extensive automation tools (e.g., vRealize) for orchestration and scaling. Management is more streamlined, but organizations are dependent on VMware for updates, features, and support, which can result in higher licensing costs.

OpenStack can be more complex to deploy, especially in large environments, as it involves setting up and configuring multiple components independently. While Horizon (the OpenStack dashboard) provides a GUI for managing resources, the platform requires extensive knowledge of the command-line interface (CLI) and scripting for full customization. Management in OpenStack is often more flexible, but it demands a higher level of technical expertise and skilled staff or the use of third-party tools for automation and monitoring.

Scalability and Flexibility

VMware is built for enterprise environments, offering high levels of scalability and the ability to manage thousands of VMs. While it integrates well with public clouds (e.g., VMware Cloud on AWS), its flexibility is somewhat limited to VMware’s ecosystem, making hybrid or multi-cloud strategies more difficult to implement compared to open source alternatives.

OpenStack is highly scalable by design and capable of handling massive environments with thousands of nodes, which is why it’s favored by telecom providers and large enterprises with complex infrastructures. OpenStack can be adapted to almost any infrastructure scenario, from small private clouds to massive public clouds. The modularity allows for easy integration of newer technologies, such as containers (via Magnum), edge computing, or hyperconverged infrastructure.

Universities like MIT deploy OpenStack for flexible cloud computing environments that support academic research, collaboration, and computational biology.

Hybrid Cloud Deployments

Organizations that require hybrid cloud setups—using a mix of private and public clouds—often use OpenStack for the private cloud component. This enables them to balance sensitive workloads on premises while utilizing public clouds for other tasks. Walmart, for example, uses OpenStack to manage its hybrid cloud infrastructure, which combines on-premises OpenStack environments with public cloud services to ensure scalability during peak demand like the holiday season.

Cloud for SaaS Providers

Software-as-a-service (SaaS) providers leverage OpenStack to build and deliver scalable cloud-based applications while maintaining full control over infrastructure. They can dynamically scale resources to meet user demand without depending on external providers. Although it has since switched over to Kubernetes, eBay initially used OpenStack to scale its platform, which handles a massive number of transactions daily.

Edge Computing

Companies managing distributed IT infrastructure, such as retail chains, manufacturing plants, or transportation hubs, can use OpenStack to enable edge computing, processing data closer to the source to reduce latency. Verizon, for example, deploys OpenStack to power edge computing solutions for its 5G network, enabling low-latency applications such as autonomous vehicles.

Cost Comparison: VMware vs. OpenStack

Several key factors come into play here, including licensing, support, maintenance, and potential hidden costs. Note: Each platform has its own pricing model.

Licensing Costs

VMware requires licensing fees for its software, typically charged per CPU socket or per VM. Licensing costs vary based on the edition (e.g., vSphere Standard, vSphere Enterprise Plus). VMware vSphere Standard is $1,394 per CPU per year and vSphere Enterprise Plus costs $4,780 per CPU per year. 

OpenStack is free and open source software, meaning there are no licensing costs. While OpenStack is free, using it effectively often requires significant investment in skilled IT staff for installation, customization, and ongoing maintenance.

Support Costs

VMware provides robust, enterprise-level support packages, which are crucial for mission-critical environments. These packages are typically offered in different tiers (e.g., Basic, Production, Premier). Basic support can be as low as $300 per year per CPU, and higher-tier support can cost tens of thousands of dollars annually. Software updates, patches, and upgrades are included with the support package but may require additional fees for access to certain premium features. VMware often requires certified administrators, which may involve costs for training and certification exams, which can range anywhere from $3,000 to $10,000 per course. Refer to this recent VMware price list for the most updated information. 

OpenStack users can rely on the large open source community for support, but it lacks the guarantees of enterprise-grade support. Support contracts with vendors like Red Hat, Canonical, or Mirantis offer professional OpenStack support, such as Red Hat’s OpenStack support with its subscription model. Training costs for OpenStack administrators and engineers can be high but are often a one-time investment.

Maintenance Costs

VMware handles maintenance through regular software updates, security patches, and new releases. This is typically included in the licensing and support fees, though large-scale upgrades or major new features may require additional payments. VMware requires specific hardware that is certified by VMware, which could involve additional costs for procuring or upgrading hardware.

OpenStack deployments require more hands-on maintenance by internal teams or third-party vendors. This includes setting up, monitoring, upgrading, and troubleshooting the cloud infrastructure. Organizations often need to invest in skilled IT professionals for regular maintenance and updates. 

Hidden Costs and Additional Expenses

Purchasing or upgrading VMware-certified hardware to meet these requirements can be expensive, especially for large deployments. Many features, such as NSX, vSAN, and disaster recovery, come as optional add-ons with additional costs. These can significantly increase the total cost of ownership (TCO).

The primary hidden cost in OpenStack deployments is the expertise required to manage and maintain the platform. Hiring or training a team of skilled OpenStack engineers is essential, and this can be a major ongoing cost. Customization and integration with existing systems can take longer and cost more in terms of development and deployment efforts. Improper configuration or lack of expertise can also lead to increased operational costs.

Hardware Costs	Can be high for VMware-certified hardware	More flexibility, but expertise needed
Hidden/Additional Costs	Add-ons for features, vendor lock-in, upgrade fees	Personnel costs, deployment complexity, potential downtime

Performance and Scalability: VMware vs. OpenStack

When comparing the performance and scalability of VMware and OpenStack, it’s important to consider how each platform handles resource management, workload distribution, and scalability options. Both platforms are designed to support enterprise-grade cloud environments, but their architectures and approaches to scaling differ significantly.

Performance

VMware provides out-of-the-box optimization features that allow for seamless performance tuning. Features like Distributed Resource Scheduler (DRS) and vMotion ensure that workloads are balanced across hosts, maintaining optimal performance even during peak demand. ESXi, is designed with low overhead, providing near-native performance. vSAN and NSX are highly optimized for virtual environments. These components offer data compression, deduplication, and network segmentation, improving overall performance.

OpenStack’s performance is largely dependent on the underlying hardware and the configuration choices. It offers high flexibility but requires careful tuning and optimization. OpenStack supports multiple hypervisors, including KVM (the most common choice), Xen, and Hyper-V. The choice of hypervisor can significantly impact performance. For example, KVM is widely used for high-performance workloads due to its low overhead and efficient resource management.

OpenStack’s Neutron service manages networking but can introduce complexity that may lead to performance bottlenecks if not configured properly. High-performance networking features like Single Root I/O Virtualization (SR-IOV) and Data Plane Development Kit (DPDK) can be used to improve throughput and reduce latency, but they require advanced expertise to implement.

Swift and Cinder allow for distributed storage, which can be optimized for performance but may require additional tuning and hardware investments (e.g., using SSDs or flash storage for critical workloads).

Scalability

VMware excels in scaling environments. vSphere allows for easy addition of hosts to clusters, enabling horizontal scaling. Features like vSphere DRS and vSphere HA ensure that resources are distributed effectively across hosts, and workloads are automatically balanced, allowing the environment to scale without degrading performance. For multi-tenant scaling (e.g., service providers), vCloud Director enables the creation of isolated virtual data centers, making it easy to scale and provide cloud services to multiple customers.

VMware also offers integration with public cloud services, such as VMware Cloud on AWS, allowing organizations to extend their on-premises VMware environments into the cloud. This hybrid scalability helps organizations handle spikes in demand while keeping sensitive workloads on premises.

OpenStack was designed to scale horizontally by adding additional compute, storage, and networking nodes as needed. This makes it particularly well-suited for public clouds, private clouds, and hybrid cloud deployments where high elasticity is required. Nova supports horizontal scaling, allowing OpenStack to scale to thousands of nodes, but it requires careful management to avoid bottlenecks in services like Neutron (networking) or Keystone (identity service).

Swift and Cinder can also scale by adding more storage nodes. Swift allows for object storage that spans multiple regions, making it ideal for environments that need to store petabytes of data (e.g., media or research organizations).

OpenStack also supports container orchestration via Magnum, allowing it to scale containerized workloads across distributed clusters. Its ability to scale down to smaller, geographically distributed environments makes it ideal for edge computing scenarios like IoT, 5G, and real-time analytics at the edge.

Security Features: VMware vs. OpenStack

Both platforms offer comprehensive security capabilities designed to protect virtualized environments. However, each approaches security differently based on its architecture, intended use, and underlying philosophy (proprietary vs. open source):

Authentication and Access Control

VMware’s vSphere provides robust authentication and access control mechanisms. It integrates seamlessly with existing Active Directory (AD) or LDAP systems to manage user accounts, allowing for single sign-on (SSO) across multiple VMware services. Administrators can assign roles to users based on predefined or custom privilege sets.

VMware has granular role-based access controls, allowing administrators to define precise permissions for each role (e.g., VM management, network configuration). This limits access to sensitive functions and data based on user roles.

Centralized authentication in vCenter Server enables secure, unified management of multiple vSphere environments, enhancing security across distributed deployments.

Microsoft’s Secure boot is available for ESXi hypervisors, ensuring that only digitally signed code runs on the hypervisor, which protects against boot-time attacks and malicious hypervisor tampering.

OpenStack’s Keystone service is responsible for authentication, authorization, and identity management. Keystone provides support for multiple authentication backends, including LDAP, SAML, and OAuth, allowing it to integrate with existing enterprise identity management solutions.

OpenStack’s architecture is built around the concept of projects (tenants), which provide isolated environments within the same cloud infrastructure. This enables strict separation of resources between users, making it highly secure in multi-tenant cloud environments.

OpenStack’s role-based access control (RBAC) system allows administrators to create custom policies that define which actions users can take based on roles assigned within each project. This ensures that access is limited to the necessary resources only.

Federated Identity in Keystone allows for cross-domain authentication, meaning users from different organizations can securely access resources across multiple OpenStack clouds with unified credentials.

Network Security

VMware’s NSX provides a comprehensive suite of networking and security tools that allow for microsegmentation, distributed firewalls, and virtual private networks (VPNs). These capabilities are designed to isolate workloads and limit the lateral movement of attackers within a network.

Microsegmentation allows for the creation of granular, software-defined network segments around individual workloads, providing security at the VM level. Each segment can have its own firewall rules, significantly reducing the attack surface. NSX provides secure connections between different environments through encrypted tunnels (e.g., VPNs) and controls traffic entering and leaving the environment. 

NSX also includes built-in load-balancing features that ensure incoming traffic is efficiently routed, reducing the risk of denial-of-service (DoS) attacks. Finally, NSX Distributed Firewall is integrated with hypervisors to provide firewall capabilities at the virtual network interface level, giving deep, distributed protection without relying on traditional perimeter firewalls.

OpenStack’s Neutron service provides network-as-a-service capabilities, allowing administrators to configure virtual networks, firewalls, load balancers, and VPNs. Neutron allows for the use of security groups, which act as virtual firewalls to control inbound and outbound traffic for instances (virtual machines). 

OpenStack also offers firewall as a service (FWaaS), which enables administrators to apply firewall rules at the network perimeter or between virtual networks. OpenStack also supports VPN as a service (VPNaaS), which allows secure, encrypted connections between OpenStack clouds or between an OpenStack cloud and external networks.

Finally, OpenStack’s Single Root I/O Virtualization (SR-IOV) for network-intensive applications allows for higher network performance with lower overhead by bypassing the hypervisor’s virtual switch while maintaining security through hardware-enforced isolation. 

Data Encryption

VMware provides robust encryption features that can be applied at multiple levels, including:

• VM encryption: Individual virtual machines can be encrypted, protecting both data at rest and data in motion. This ensures that sensitive information inside VMs is safeguarded against unauthorized access.
• vSAN encryption: For storage-level encryption, VMware’s vSAN includes encryption at the disk level. Data is automatically encrypted on storage devices, protecting against physical breaches (e.g., stolen disks).
• Encrypted vMotion: VMware’s vMotion enables encrypted live migration of VMs between hosts, protecting the data from being intercepted during migration.

OpenStack’s Cinder supports volume encryption, ensuring that data stored on virtual disks is protected. Cinder can integrate with Key Management Services (KMS), such as Barbican, to securely manage encryption keys. Swift supports data encryption at rest, ensuring that stored objects are encrypted using AES-256 encryption.

Compliance and Auditing

VMware’s vRealize Log Insight provides detailed logging and auditing capabilities, allowing administrators to monitor security events and maintain detailed records of system changes. This is critical for organizations with strict compliance requirements, such as HIPAA or PCI-DSS.

VMware also provides preconfigured compliance templates that help organizations meet regulatory requirements. These templates ensure that virtual infrastructure configurations adhere to standards like CIS, NIST CSF 2.0, and ISO. Finally, VMware publishes security hardening guides, offering recommendations for securing vSphere environments, from configuration to management practices.

OpenStack includes logging capabilities through various services (e.g., Keystone logs authentication attempts). However, organizations typically deploy third-party solutions like ELK (Elasticsearch, Logstash, Kibana) or Sentry for centralized logging and auditing.

OpenStack’s Ceilometer service provides monitoring and metering of resources, offering insight into the usage patterns of resources, helping with security auditing and compliance monitoring.

OpenStack also offers security guidelines and best practices through the OpenStack Security Guide. This guide covers key aspects such as securing API endpoints, hardening hypervisors, and encrypting communications.

OpenStack’s Modular Layer 2 (ML2) plugin for Neutron allows integration with software-defined networking (SDN) controllers, giving organizations more control over network traffic monitoring and compliance.

Patching and Vulnerability Management

VMware has a well-established process for addressing vulnerabilities, issuing regular security advisories, and providing updates to address critical vulnerabilities. VMware’s advisory program ensures that customers are informed of the latest security threats and patch availability. VMware also provides a robust tool for patch management in virtual environments: vSphere Update Manager (VUM), which automates the process of applying security patches to vSphere hosts and VMs, ensuring that systems remain secure without requiring extensive manual intervention.

OpenStack does not have a native patch management tool comparable to VMware’s VUM. Patching OpenStack environments typically requires manual intervention or custom automation scripts, which can be more time-consuming.
