Azure Virtual Machines vs OpenvSwitch: What are the differences?


Azure Virtual Machines and OpenvSwitch are both widely used technologies in the field of cloud computing and networking. However, they have key differences in terms of their functionality and features. This article aims to highlight and explain these differences in a concise manner.

  1. Deployment and Management: Azure Virtual Machines are cloud-based virtual machines that can be easily deployed and managed through the Azure portal. On the other hand, OpenvSwitch is an open-source virtual switch software that needs to be installed and configured on each individual host.

  2. Focus on Virtualization: Azure Virtual Machines are primarily designed for running virtualized workloads in the cloud. They provide a wide range of pre-configured virtual machine images and sizes, making it easy to set up and deploy virtual machines for various purposes. OpenvSwitch, however, is a virtual switch that focuses more on network virtualization, providing advanced network management capabilities like overlay networks and network slicing.

  3. Vendor Lock-in: Azure Virtual Machines are a proprietary service provided by Microsoft Azure, which means they are tied to the Azure ecosystem. While Azure provides excellent integration with other Azure services, it may limit flexibility if one wants to migrate to a different cloud provider. On the other hand, OpenvSwitch is open-source and can be used with different vendors and platforms, providing more flexibility and avoiding vendor lock-in.

  4. Scalability: Azure Virtual Machines are built on Azure's infrastructure, which provides a high level of scalability. Users can easily scale up or down their virtual machine instances based on their requirements. OpenvSwitch, being a virtual switch software, does not provide scalability on its own. However, it can be used in conjunction with other scalability features and tools offered by the underlying infrastructure.

  5. Support and Community: Azure Virtual Machines are backed by Microsoft's extensive support and documentation resources. They also have a large user community and ecosystem, which makes it easier to find solutions to common problems and receive timely support. OpenvSwitch, being an open-source project, has an active community of developers and users who contribute to its development and provide support through various forums and channels.

  6. Cost Considerations: Azure Virtual Machines are a part of Microsoft Azure's pricing model, which comes with its own cost structure based on factors such as virtual machine size, region, and usage. OpenvSwitch, being an open-source software, is free to use and does not have any direct costs associated with it. However, there might be indirect costs involved in terms of infrastructure and maintenance.

In Summary, Azure Virtual Machines and OpenvSwitch have key differences in terms of deployment and management, focus on virtualization, vendor lock-in, scalability, support and community, and cost considerations. Azure Virtual Machines are cloud-based virtual machines with an emphasis on easy deployment and management, while OpenvSwitch is an open-source virtual switch software focused on network virtualization.

      What are some alternatives to Azure Virtual Machines and OpenvSwitch?
      Azure SQL Database
      It is the intelligent, scalable, cloud database service that provides the broadest SQL Server engine compatibility and up to a 212% return on investment. It is a database service that can quickly and efficiently scale to meet demand, is automatically highly available, and supports a variety of third party software.
      Azure App Service
      Quickly build, deploy, and scale web apps created with popular frameworks .NET, .NET Core, Node.js, Java, PHP, Ruby, or Python, in containers or running on any operating system. Meet rigorous, enterprise-grade performance, security, and compliance requirements by using the fully managed platform for your operational and monitoring tasks.
      Amazon EC2
      It is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale computing easier for developers.
      Laravel Homestead
      Laravel Homestead is an official, pre-packaged Vagrant "box" that provides you a wonderful development environment without requiring you to install PHP, HHVM, a web server, and any other server software on your local machine. Homestead runs on any Windows, Mac, or Linux system, and includes the Nginx web server, PHP 5.6, MySQL, Postgres, Redis, Memcached, and all of the other goodies you need to develop amazing Laravel applications.
      HHVM (HipHop Virtual Machine)
      HHVM uses a just-in-time (JIT) compilation approach to achieve superior performance while maintaining the flexibility that PHP developers are accustomed to. To date, HHVM (and its predecessor HPHPc before it) has realized over a 9x increase in web request throughput and over a 5x reduction in memory consumption for Facebook compared with the PHP 5.2 engine + APC.
