Evolution to vSphere 6.7 Chapter 1 [ 9 ] The VMware vSphere suite includes ESXi (the evolution of ESX Server) for the virtualization layer and the vCenter Server for the management layer. Compute virtualization is only the first step here; to move to a real cloud computing infrastructure, you will not only need to compute resource abstraction (provided by virtualization) but also operation automation and agility (both of these are only partially obtainable through virtualization). Finally, this approach should not only be applied to the compute virtualization but also to the other resources, such as storage, networking, and security. Today, VMware products can be used to fulfill this vision. There are three infrastructure pillars that VMware virtualizes: Compute resources—VMware vSphere Storage resources—VMware vSAN Network resources—VMware NSX Together, these products build a unified platform for delivering any service with unmatched performance. In this book, we are focusing primarily on VMware vSphere, but we will also touch on vSAN and NSX.

The idea here is to provide the agility and flexibility that is required by a business while enabling the right level of performance, continuity, and security that Itis responsible for delivering Any application: vSphere is the best platform to run any application from traditional enterprise applications to cloud-native workloads. VMware is very successful when running traditional applications, and now the goal is to extend this to cloud-native workloads as well [10]

Evolution to oSphere 6.7 Chapter 1 Software-defined data center(SDDc) In rmer VMware CTO Steve Herrod explained this vision with the new concept of the SDDC, where all infrastructure elements(computing, networking, storage, and security) are virtualized and delivered as a service using a cloud computing model Unified Software-Defined Datacenter Management Compute Storage Network Resources Physical Hardware Virtualization is no longer the final destination of the digital transformation journey it has become the starting point, an essential requirement, and a foundation for digital businesses. VMware has addressed these needs by extending both its product portfolio and its vision. Together, VMware vSphere, NSX, and vSAN are unified building blocks which form an SDDC. As we will explain later, this approach incorporates nicely with hyper- converged infrastructure, a physical server that contains not only computer resources but also local storage devices for building software-defined storage. Hyper-converged servers are physical infrastructure blocks for SDDCs As an extension to this approach, the Cloud Foundation product can be leveraged VMware Cloud Foundation is an integrated software platform that automates the deployment and life cycle management of a complete SDDC on a standardized hyper erged architecture. This can be deployed on-premises on a broad range of supported hardware, or consumed as a service in the public cloud (VMware Cloud on AWS or VMware Cloud Providers [11]

Different workloads may require different infrastructure platforms to meet the IT and business requirements or objectives In the vSphere 6.5 release, VMware introduced vSphere Integrated Containers(VIC), a platform to bring containers into an existing vSphere environment simply and easily. With VIC, it is possible to deliver an enterprise container infrastructure that provides not only agility for developers(by using the containers) but also full control for vSphere operations teams, where containers can now be managed with the same concepts and skills as standard VMs, without requiring any changes in processes or tools VIC are structured into the following components VIC engine: Docker remote is an API-compatible engine which is deeply integrated into vSphere(6.0, 6.5, 6.7) for instantiating container images that run as VMs, with support for distributing images to remote offices/branch offices [13]
