Mitigating Risks in the Wake of Broadcom's Acquisition of VMware
A Call to Action for Cloud-Native Fence Sitters
Broadcom has recently completed its acquisition of VMware from Dell, a move with significant implications for enterprises heavily invested in VMware's virtualization technologies. This $61 billion deal, finalized in November 2023, places VMware's extensive portfolio of cloud, data center, and virtualization solutions under Broadcom's control. This acquisition raises substantial concerns about potential increases in licensing costs, with estimates suggesting hikes anywhere from 50% to 400%. Historically, Broadcom's handling of acquired companies has led to mixed experiences for customers, and this acquisition could introduce similar challenges.
Given these potential disruptions, many organizations are considering alternative strategies to mitigate the risks associated with increased costs and potential service changes. While many consulting firms and competitors are recommending transitioning to different monolithic virtualization stacks, this approach might not address the core issues effectively and merely kicks the can down the road for dealing with price lock-in. Instead, a more forward-thinking strategy involves transitioning from full-stack virtualization to cloud-native architectures. This shift leverages containerization and microservices to enhance resiliency, flexibility, and scalability, addressing many of the limitations inherent in traditional virtualization. We will discuss this approach in this article.
VMware's Evolution: From Perpetual Licenses to Subscription-Based Models
VMware has been a cornerstone in enterprise virtualization and cloud computing, known for its innovative solutions and strong customer relationships. Founded in 1998, VMware quickly changed the IT landscape with its introduction of the first commercially successful virtualization platform, VMware vSphere. This technology allowed businesses to run multiple operating systems and applications on a single physical server, optimizing resource utilization and significantly reducing costs. This model dovetailed nicely into the solutions hyperscalers wanted to offer, integrating seamlessly with broader trends in cloud computing and providing robust, scalable solutions that enterprises have come to rely on.
Over the years, VMware expanded its product offerings to include a suite of cloud management, security solutions, and cloud-native containerization options like VMware Tanzu. These products cater to the growing demand for hybrid and multi-cloud environments, enabling enterprises to manage and secure their IT infrastructure seamlessly across on-premises, private cloud, and public cloud environments. This extensive portfolio has helped VMware establish a dominant position in the market and build a loyal customer base. In fiscal year 2023, VMware reported revenues of $13.35 billion, with subscription and SaaS revenues growing by 25% year-over-year to $4.01 billion. This growth reflects the increasing adoption of VMware's solutions for modernizing private cloud infrastructure and migrating applications to public clouds.
A key factor behind VMware's strong customer retention is its collaborative approach to innovation. VMware has consistently worked closely with its customers and partners to develop solutions that address real-world business challenges. Programs like the Accelerated Co-innovation Engineering Program and partnerships with leading technology companies have enabled VMware to stay ahead of industry trends and deliver valuable innovations. Additionally, VMware's commitment to providing robust support and updates through its perpetual licensing model further cemented its relationship with customers.
Moving into December 2023, VMware, now under Broadcom's ownership, transitioned to a subscription-based model. This shift aims to align with industry standards, offering continuous innovation and predictable investments but potentially increasing costs for customers over time. Many enterprises valued the flexibility of owning perpetual licenses with optional support, but they now need to adapt to the new subscription model to continue receiving updates and support. The uncertainty of a subscription-based model, combined with potential price hikes to recoup the investment from acquiring VMware from Dell, has left many VMware users concerned about future costs and stability.
So, Are There Alternatives to VMware?
Yes, there are many hypervisor alternatives, each with distinct features, and pricing models. Organizations, especially those with limited budgets and shrinking operating margins, are actively exploring these options to address rising costs and vendor lock-in. While I have developed comprehensive matrices to help clients choose the best solutions, this section will only briefly touch on these alternatives since our focus is on transitioning to cloud-native technologies, either alongside or replacing traditional hypervisors.

Each of these alternatives has its own strengths and considerations, depending on the specific needs and existing infrastructure of an organization, and exploring these options might help businesses find cost-effective and flexible solutions that align with their strategic goals. However, it should be noted that any migration of this type can be very disruptive and costly, and should not be undertaken without significant planning and oversight. While VMware is banking on this FUD factor, some customers may choose to make the move regardless, as they see no other long term alternative that keeps them in the black.
Is the Hypervisor Going Away?
No, the hypervisor is not going away. Monolithic application stacks — those tightly integrated with OS, drivers, middleware, and underlying hardware and/or requiring isolation — are still prevalent and will continue to exist for the foreseeable future. While some changes are occurring in how hypervisors are offered and integrated, the core technology remains vital and is continuously being developed and supported. The shift towards hybrid cloud solutions underscores the continued importance of hypervisors, integrating on-premises infrastructure with cloud services rather than phasing out the technology altogether. This direction aims to provide businesses with a cohesive hybrid environment, leveraging both on-premises and cloud resources effectively.
At present, hypervisors and cloud-native services are being deployed in parallel, but attrition will likely come quickly for hypervisor-based architectures. Cloud-native technologies, such as containers and microservices, offer a vastly different architecture focused on scalability, flexibility, and efficient resource management. These technologies enable applications to be built and deployed in a more modular and dynamic manner, providing advantages in terms of agility and continuous delivery. As organizations increasingly adopt these modern computing paradigms, the reliance on traditional hypervisor-based architectures is expected to diminish, leading to a gradual transition towards more cloud-native environments.
All this being said, the recent Broadcom-VMware shakeup may further accelerate the shift from hypervisors to cloud-native applications as companies seek better ways to roll out applications at lower price points. The uncertainty and potential changes in pricing and support models brought by this acquisition are prompting many businesses to reconsider their virtualization strategies. By adopting cloud-native solutions, organizations can achieve greater cost efficiency, scalability, and flexibility, which are crucial for staying competitive in today's fast-paced technological landscape. This shift is likely to drive more companies to explore and implement cloud-native architectures, hastening the decline of traditional hypervisor-based systems.
Let’s Take a Closer Look at Cloud-Native Architectures
Cloud-native architectures represent a modern approach to designing and deploying applications that fully leverage cloud computing environments. It's an evolution beyond traditional virtualization, with applications designed to exploit cloud capabilities through containerization, packaging applications and their dependencies into lightweight, portable units that can be infinitely chained to deliver agile solution patterns. This means that cloud-native architectures allow for the dynamic composition and recomposition of services and applications to meet changing demands quickly and efficiently.
These architectures are built around several key principles which we will now review:
Microservices: This architectural style breaks down applications into small, independent services that can be developed, deployed, and scaled independently. Each microservice focuses on a specific business function and communicates with other services through well-defined APIs, facilitating continuous delivery and reducing the complexity of managing large, monolithic applications.
Containerization: Containers encapsulate applications and their dependencies, providing a consistent runtime environment across different stages of development and production. Technologies like Docker have popularized containerization, enabling developers to create portable and reproducible application environments that can run seamlessly on any infrastructure.
Dynamic Orchestration: Tools like Kubernetes automate the deployment, scaling, and management of containerized applications. Orchestration platforms ensure that applications remain highly available and can efficiently handle varying workloads by dynamically allocating resources as needed.
By adopting cloud-native architectures, organizations can achieve faster time-to-market, improved operational efficiency, and the ability to respond more quickly to changing business demands. This approach aligns well with the growing emphasis on digital transformation and the need for businesses to remain agile and competitive in a rapidly evolving environment.
The more popular containerization and cloud-native solutions are listed below (again, keep in mind current and best pricing is not always available publicly and is subject to change):
Docker: Docker is an open-source platform that automates the deployment, scaling, and management of applications using containerization. It packages applications and their dependencies into portable containers that can run consistently across different environments. Docker is free to use, with enterprise editions available that include advanced security, management, and support features. Pricing for Docker Enterprise starts at around $500 per node annually.
Kubernetes: Kubernetes is an open-source container orchestration platform designed to automate deploying, scaling, and operating containerized applications. It manages clusters of containers, ensuring high availability, scalability, and disaster recovery. Kubernetes is free to use, but enterprise support and additional features are available through various Kubernetes service providers like Google Kubernetes Engine (GKE), Amazon Elastic Kubernetes Service (EKS), and Azure Kubernetes Service (AKS). Costs vary depending on the provider and resource usage.
Red Hat OpenShift: Red Hat OpenShift is a comprehensive Kubernetes platform that includes developer and operational tools to build, deploy, and manage containerized applications. It offers a consistent environment for application development and deployment and is frequently paired with Red Hat Virtualization for managing both containerized and virtualized workloads. OpenShift uses a subscription-based model, starting at about $1,000 per node per year, including support and updates.

GKE provides features like automated upgrades, scaling, and security patches. Pricing is based on the resources consumed and additional features selected, with basic cluster management free for small clusters.
Amazon Elastic Kubernetes Service (EKS) and Azure Kubernetes Service (AKS): EKS and AKS are managed Kubernetes services provided by Amazon Web Services (AWS) and Microsoft Azure, respectively. Both services allow users to run Kubernetes without needing to install and operate their own Kubernetes control plane or nodes. EKS and AKS integrate with their respective cloud services to provide scalability, security, and high availability. Both offer features like automated upgrades, scaling, and monitoring. Pricing for EKS is based on the number of nodes and the AWS resources used, while pricing for AKS is based on the resources consumed, with basic cluster management free for small clusters.
NOTE: Nutanix and Promox VE, detailed in the hypervisor alternatives section, provide both hypervisor and containerization functionality.
While some applications can be easily translated to containerized environments, and vendors are now releasing container-friendly versions of their applications, it's important to consider that the way we develop applications for these environments changes significantly. This includes adopting new development practices, utilizing microservices architectures, and focusing on scalability and resilience. We will discuss these shifts in the next section.
Developing Applications for the Cloud-Native Construct
Cloud-native application development is a vast topic, worthy of its own article or even a book, but let's review it at a high level. The transition from traditional, monolithic virtualized machines to a microservices architecture marks a significant transformation in application development. Traditionally, applications were built as monolithic entities where all components — user interface, business logic, and data access — were tightly integrated and ran within a single process. This approach simplified initial development but became cumbersome as applications grew. Scaling required duplicating the entire system, updates necessitated redeploying the whole application, and a failure in one component could impact the entire system. In contrast, a microservices architecture decomposes an application into a collection of loosely coupled services, each responsible for a specific function. These services communicate through well-defined APIs and can be developed, deployed, and scaled independently. This shift is central to the cloud-native construct, bringing enhanced flexibility, scalability, and resilience.
Central to cloud-native applications is containerization, which packages an application and its dependencies into a lightweight, portable unit. Docker is a popular tool for managing these containers. Once containerized, orchestration tools like Kubernetes automate deployment, scaling, and management, ensuring containers run as desired, handle scaling needs, and provide self-healing by restarting failed containers. Effective API management is crucial in a microservices architecture, with API gateways managing, securing, and monitoring interactions between services. Additionally, adopting DevOps practices and implementing continuous integration/continuous deployment (CI/CD) pipelines are vital for accelerating development cycles and maintaining high-quality releases through automated testing, integration, and deployment.
A service mesh, such as Istio, provides a dedicated infrastructure layer for managing service-to-service communication, offering advanced features like traffic management, security, and observability. This infrastructure layer simplifies the management of microservices, allowing for smoother communication and data flow. The benefits of cloud-native development are substantial. The modular nature of microservices allows for quicker development and deployment cycles, enabling organizations to respond swiftly to market changes and customer needs. Operational efficiency is enhanced by decoupling services and automating processes, reducing complexity and improving resource utilization. Improved resilience is realized by isolating and managing failures within individual services, leading to higher levels of uptime. Cost-effectiveness is also a significant advantage, as cloud-native architectures can optimize costs by scaling services independently and using cloud resources more efficiently.
However, the shift to microservices introduces complexity in managing multiple services, inter-service communication, and data consistency. Proper planning and tooling are essential. Ensuring security in a microservices environment requires robust API security, identity management, and data protection. Implementing security best practices and leveraging tools like service meshes help mitigate these risks. Adopting a cloud-native approach often necessitates a cultural shift within the organization, embracing DevOps practices, fostering collaboration, and promoting continuous improvement.
Developing applications for the cloud-native construct involves rethinking traditional approaches and embracing new paradigms that emphasize agility, scalability, and resilience. By leveraging containerization, orchestration, and microservices, organizations can build applications better suited to modern cloud environments, delivering greater value to users and stakeholders. Cloud-native application development transforms the way organizations build and manage applications, addressing the limitations of monolithic architectures and harnessing the full potential of cloud computing environments.
Financial Risk Mitigation at the Heart of the Matter
As organizations face the potential cost increases and service changes resulting from the Broadcom-VMware acquisition, it's critical to approach this transition strategically. While cloud-native architectures offer compelling advantages in terms of scalability, flexibility, and efficiency, financial risk mitigation remains a central concern.
Here are key strategies for mitigating financial risks while transitioning to cloud-native architectures:
Evaluate Total Cost of Ownership (TCO): Conduct a thorough analysis of the TCO for both current VMware-based solutions and potential cloud-native alternatives. This includes considering not only licensing costs but also operational expenses, training, and migration efforts.
Leverage Open-Source Solutions: Utilize open-source technologies where possible to reduce licensing fees and gain more control over your IT infrastructure. Tools like Kubernetes and Docker offer robust, community-supported alternatives to proprietary solutions.
Adopt a Phased Migration Approach: Gradually transition from traditional virtualization to cloud-native environments. Start with non-critical applications to minimize disruption and gain experience before moving mission-critical workloads.
Optimize Cloud Spending: Implement cloud cost management practices, such as monitoring usage, optimizing resource allocation, and leveraging reserved instances or spot pricing to control cloud expenses.
Build a Resilient Architecture: Design cloud-native applications with redundancy and fault tolerance in mind to minimize the risk of downtime and associated costs. This includes using microservices to isolate failures and container orchestration tools to manage resources dynamically.
Foster Collaboration and Skill Development: Invest in training and development to build cloud-native expertise within your team. Encourage collaboration between development and operations teams to streamline processes and enhance efficiency.
Utilize Managed Services: Consider managed cloud services to offload operational overhead and benefit from expert support and maintenance, which can reduce costs and improve service reliability.
Engage with Trusted Partners: Work with experienced consultants and cloud providers to develop a tailored migration strategy that aligns with your business goals and minimizes financial risks.
By embracing these strategies, organizations can navigate the uncertainties of the Broadcom-VMware acquisition and transition to cloud-native architectures with greater confidence. The goal is to achieve a more agile, scalable, and cost-effective IT environment that supports long-term business objectives while mitigating financial risks.
