Network virtualization combines network resources to integrate several physical networks, segment a network, or construct software networks among VMs. IT teams can construct numerous separate virtual networks using network virtualization. Virtual networks can be added and scaled without changing hardware. Teams can start up logical networks more rapidly in response to business needs using network virtualization. This adaptability improves service delivery, efficiency, and control. Importance of Network Virtualisation Network virtualization entails developing new rules for the delivery of network services. This involves software-defined data centers (SDDC), cloud computing, and edge computing. Virtualization assists in the transformation of networks from rigid, wasteful, and static to optimized, agile, and dynamic. To ensure agility and speed, modern virtual networks must keep up with the needs of cloud-hosted, decentralized applications while addressing cyberthreats. You can deploy and upgrade programs in minutes thanks to network virtualization. This eliminates the need to spend time setting up the infrastructure to accommodate the new applications. What is the Process of Network Virtualization? Several network functions that were previously done manually on hardware are now automated through network virtualisation. Network managers can construct, maintain, and provide networks programmatically in software while employing the hardware as a packet-forwarding backplane. Physical network resources, such as virtual private networks (VPNs), load balancing, firewalling, routing, and switching, are pooled and supplied in software. To do this, you merely require Internet Protocol (IP) packet forwarding from the hardware or physical network. Individual workloads, such as virtual machines, can access network services that have been distributed to a virtual layer. There are several kinds of virtual machines accessible. The finest virtual machines enable network administrators to access all parts of a network from a single point of access. Closing Lines Network virtualization will remain a critical component in both business and carrier network architectures. Network virtualization projects in the future will inevitably incorporate zero trust, automation, and edge and cloud computing.

IT administrators can allocate and manage the virtual storage unit with the help of management software, which facilitates streamlined storage tasks like backup, archiving, and recovery. There are three types of storage virtualization: file-level, block-level, and object-level. File-level consolidates multiple file systems into one virtualized system for easier management. Block-level abstracts physical storage into logical volumes allocated to VMs. Object-level creates a logical storage pool for more flexible and scalable storage services to VMs. The storage virtualization segment held an industry share of more than 10.5% in 2021 and is likely to observe considerable expansion through 2030 (Source: Global Market Insights) 2.3 Network virtualization Any computer network has hardware elements such as switches, routers, load balancers and firewalls. With network virtualization, virtual machines can communicate with each other across virtual networks, even if they are on different physical hosts. Network virtualization can also enable the creation of isolated virtual networks, which can be helpful for security purposes or for creating test environments. The following are two approaches to network virtualization: 2.3.1 Software-defined networking Software-defined networking (SDN) controls traffic routing by taking over routing management from data routing in the physical environment. For example, programming the system to prioritize video call traffic over application traffic to ensure consistent call quality in all online meetings. 2.3.2 Network function virtualization Network function virtualization technology combines the functions of network appliances, such as firewalls, load balancers, and traffic analyzers, that work together to improve network performance. The global Network function virtualization market size was valued at USD 12.9 billion in 2019 and is projected to reach USD 36.3 billion by 2024, at a CAGR of 22.9%, during the forecast period(2019-2024). (Source: MarketsandMarkets) 2.4 Data virtualization Data virtualization is the process of abstracting, organizing, and presenting data in a unified view that applications and users can access without regard to the data's physical location or format. Using virtualization techniques, data virtualization platforms can create a logical data layer that provides a single access point to multiple data sources, whether on-premises or in the cloud. This logical data layer is then presented to users as a single, virtual database, making it easier for applications and users to access and work with data from multiple sources and support cross-functional data analysis. Data Virtualization Market size was valued at USD 2.37 Billion in 2021 and is projected to reach USD 13.53 Billion by 2030, growing at a CAGR of 20.2% from 2023 to 2030.

Impact of Virtualized VMs on Business Enterprises Virtualization can increase the adaptability of business processes. The servers can support different operating systems (OS) and applications as the software is decoupled from the hardware. Business processes can be run on virtual computers, with each virtual machine running its own OS, applications, softwares and set of programs. 3.1 Virtualization as a Game-Changer for Business Models The one server, one application model can be abolished using virtualization, which was inefficient because most servers were underutilized. Instead, one server can become many virtual machines using virtualization software, each running on a different operating system such as Windows, Linux, or Apache. Virtualization has made it possible for companies to fit more virtual servers onto fewer physical devices, saving them space, power, and time spent managing them. The adoption of virtualization services is significantly increased by industrial automation systems. Industrial automation suppliers offer new-generation devices to virtualize VMs and software-driven industrial automation operations. This will solve problems with important automation equipment like Programmable Logic Controller (PLCs) and Distributed Control Systems (DCS), leading to more virtualized goods and services in industrial automation processes. 3.2 Evaluating IT Infrastructure Reformation IT infrastructure evaluation for virtualization needs to look at existing systems and processes along with finding opportunities and shortcomings.

The modern application world is advancing at an unprecedented rate. However, the new possibilities these transformations make available don’t come without complexities. IT teams often find themselves under pressure to keep up with the speed of innovation. That’s why VMware provides a production-ready container platform for customers that aligns to upstream Kubernetes, VMware Tanzu Kubernetes Grid Integrated (formerly known as VMware Enterprise PKS). By working with VMware, customers can move at the speed their businesses demand without the headache of trying to run their operations alone. Our offerings help customers stay current with the open source community's innovations while having access to the support they need to move forward confidently. Many changes have been made to Tanzu Kubernetes Grid Integrated edition over the past year that are designed to help customers keep up with Kubernetes advancements, move faster, and enhance security. Kubernetes updates The latest version, Tanzu Kubernetes Grid Integrated 1.13, bumped to Kubernetes version 1.22 and removed beta APIs in favor of stable APIs that have since evolved from the betas. Over time, some APIs will evolve. Beta APIs typically evolve more often than stable APIs and should therefore be checked before updates occur. The APIs listed below will not be served with v1.22 as they have been replaced by more stable API versions: Beta versions of the ValidatingWebhookConfiguration and MutatingWebhookConfiguration API (the admissionregistration.k8s.io/v1beta1 API versions) The beta CustomResourceDefinition API (apiextensions.k8s.io/v1beta1) The beta APIService API (apiregistration.k8s.io/v1beta1) The beta TokenReview API (authentication.k8s.io/v1beta1) Beta API versions of SubjectAccessReview, LocalSubjectAccessReview, SelfSubjectAccessReview (API versions from authorization.k8s.io/v1beta1) The beta CertificateSigningRequest API (certificates.k8s.io/v1beta1) The beta Lease API (coordination.k8s.io/v1beta1) All beta Ingress APIs (the extensions/v1beta1 and networking.k8s.io/v1beta1 API versions) Containerd support Tanzu Kubernetes Grid Integrated helps customers eliminate lengthy deployment and management processes with on-demand provisioning, scaling, patching, and updating of Kubernetes clusters. To stay in alignment with the Kubernetes community, Containerd will be used as the default container runtime, although Docker can still be selected using the command-line interface (CLI) if needed. Networking Several updates have been made in regards to networking as well including support of Antrea and NSX-T enhancements. Antrea support With Tanzu Kubernetes Grid Integrated version 1.10 and later, customers can leverage Antrea on install or upgrade to use Kubernetes network policies. This enables enterprises to get the best of both worlds: access to the latest innovation from Antrea and world-class support from VMware. NSX-T enhancements NSX-T was integrated with Tanzu Kubernetes Grid Integrated to simplify container networking and increase security. This has been enhanced so customers can now choose the policy API as an option on a fresh installation of Tanzu Kubernetes Grid Integrated. This means that users will have access to new features available only through NSX-T policy API. This feature is currently in beta. In addition, more NSX-T and NSX Container Plug-in (NCP) configuration is possible through the network profiles. This operator command provides the benefit of being able to set configurations through the CLI, and this is persistent across lifecycle events. Storage enhancements We’ve made storage operations in our customers’ container native environments easier, too. Customers were seeking a simpler and more secure way to manage Container Storage Interface (CSI), and we introduced automatic installation of the vSphere CSI driver as a BOSH process beginning with Tanzu Kubernetes Grid Integrated 1.11. Also, as VCP will be deprecated, customers are advised to use the CSI driver. VCP-to-CSI migration is a part of Tanzu Kubernetes Grid Integrated 1.12 and is designed to help customers move forward faster. Enhanced security Implementing new technologies provides users with new capabilities, but it can also lead to new security vulnerabilities if not done correctly. VMware’s goal is to help customers move forward with ease and the confidence of knowing that enhancements don’t compromise core security needs. CIS benchmarks This year, Tanzu Kubernetes Grid Integrated continued to see improvements that help meet today’s high security standards. Meeting the Center for Internet Security (CIS) benchmarks standards is vital for Tanzu Kubernetes Grid Integrated. In recent Tanzu Kubernetes Grid Integrated releases, a few Kubernetes-related settings have been adjusted to ensure compliance with CIS requirements: Kube-apiserver with --kubelet-certificate-authority settings (v1.12) Kube-apiserver with --authorization-mode argument includes Node (v1.12) Kube-apiserver with proper --audit-log-maxage argument (v1.13) Kube-apiserver with proper --audit-log-maxbackup argument (v1.13) Kube-apiserver with proper --audit-log-maxsize argument (v1.13) Certificate rotations Tanzu Kubernetes Grid Integrated secures all communication between its control plane components and the Kubernetes clusters it manages, using TLS validated by certificates. The certificate rotations have been simplified in recent releases. Customers can now list and simply update certificates on a cluster-by-cluster basis through the “tkgi rotate-certificates” command. The multistep, manual process was replaced with a single CLI command to rotate NSX-T certificates (available since Tanzu Kubernetes Grid Integrated 1.10) and cluster-by-cluster certificates (available since Tanzu Kubernetes Grid Integrated 1.12). Hardening of images Tanzu Kubernetes Grid Integrated keeps OS images, container base images, and software library versions updated to remediate the CVEs reported by customers and in the industry. It also continues to use the latest Ubuntu Xenial Stemcell latest versions for node virtual machines. With recent releases and patch versions, the version of dockerd, containerd, runc, telegraf, nfs-utils had been bumped to the latest stable and secure versions as well. By using Harbor as a private registry management service, customers could also leverage the built-in vulnerability scan features to discover the application images CVEs. VMware is dedicated to supporting customers with production readiness by enhancing the user experience. Tanzu Kubernetes Grid Integrated Edition has stayed up to date with the Kubernetes community and provides customers with the support and resources they need to innovate rapidly.
