Explaining how we started with basic virtualization, mainly for test/dev 10 years ago
As companies where getting more successful and servers become more powerfull, more and more workloads, including production worksloads where added as virtual machines.
VMware vSphere™ is a cloud operating system - A cloud operating system is a new category of software that is specifically designed to holistically manage large collections of infrastructure – CPUs, storage, networking – as a seamless, flexible and dynamic operating environment. Analogous to the operating system that manages the complexity of an individual machine, the cloud operating system manages the complexity of a datacenter. Although alternative approaches may be pursued, VMware believes that virtualization is the key underpinning technology to enable the cloud.The cloud OS comprises infrastructure services that transform server, storage and network hardware into a shared resource and application services that are built in and available to all applications that run on it.Also equally important for an OS is the vibrant ecosystem that builds and complements it providing plug and play services to users
vStorage Thin Provisioning optimizes storage costs through the most efficient use of storage in virtual environments. Storage requests more often than not are usually overestimated by users mostly to avoid having to go through the request/approval process. With vStorage Thin Provisioning, IT depts can now assure business users of storage space availability while deferring the actual costs of purchasing storage to when it is really needed. Full reporting and alerting on allocation and consumption ensure that virtual machines don’t really run out of storage, Storage VMotion and Volume Grow (next slide) ensure that virtual machines can either migrate to datastores with additional storage or volumes can be increased in size when consumption approaches allocation.
VMware vShield Zones, a new security service for VMware’s Cloud OS, vSphere, ensures strict compliance with security policies and industry regulations for user data as customers adopt cloud computing with virtual environments for increased efficiency and flexibility. Previously, compliance required diverting network traffic to external physical appliances resulting in disconnected ‘islands’ of infrastructure. With VMware vShield Zones, customers can now create logical zones in the virtual datacenter that span all of the shared physical resources, and each zone represents a distinct level of trust and confidentiality. This allows businesses to comply with corporate security policies and regulations on data privacy while still running applications efficiently on shared computing resource pools. Traditional security products, such as firewall appliances, require that all network activity pass through a handful of fixed physical locations in order to be monitored. Virtualized applications, in contrast can be migrated between physical hosts for higher resource efficiency and improved uptime. Therefore, companies virtualizing security sensitive applications faced the choice of either leveraging virtualization capabilities such as live migration for optimal load balancing and availability, or enforcing strict security compliance. To solve that dilemma, most customers ended up dividing their virtual environments into smaller, less efficient clusters for areas such as their Internet-facing demilitarized zones (DMZ’s) or consumer credit data processing systems subject to Payment Card Industry regulations. VMware vShield Zones enables customers to create security zones within enterprises or in multi-tenant cloud infrastructures, where security policies are enforced even as virtual machines dynamically migrate between hardware devices. Deployed as a virtual appliance and integrated into vCenter Server, vShield Zones makes it easy to centrally manage and enforce compliance with security policies across large pools of servers and virtual machines. Built-in auditing capabilities make compliance straightforward and verifiable.
VMware vCenter Server provides greater operational control of vSphere environments through automation and deep visibility into every level of virtual infrastructure. It scales to manage large environments and integrates with industry-leading systems management solutions for enterprise-wide system management.
VMware View helps to address an expanding range of customer use cases including OS migrations, mobile and remote desktop access, contract and offshore employees, as well as Business continuity and Disaster Recovery.More specific use cases can be found in the appendix of this presentation.
The entire VMware portfolio is aimed at removing and reducing complexity in IT, leveraging a cloud computing approach. Here are the basics:vSphere, the industry’s leading virtualization platform, is the foundation for building out a cloud architecture. It is step 1 on the journey. View takes the benefits of pooling, automation, control, etc. into play for desktops, which is actually the largest workload base in the enterprise. Thus being built on and extending vSphere, since desktop virtualization IS a datacenter problem, and needs to conform into the cloud architecture.vCenter brings automation, simplification, etc. at the infrastructure level. Also note that vSphere + vCenter + View are used by cloud service providers to build out public cloud infrastructure as well. Same foundation for private and public clouds. “Redwood” is a project that is delivering the next level of abstraction, managing services across cloud infrastructure – both private and public. It will become the common management model across private clouds and VMware virtualized public clouds (i.e. vCloud partners).Springsource presents the frameworks and programming model for the cloud, freeing developers from having to be concerned with how and where to deploy applications, whether internally in a private cloud, in a VMware virtualized public cloud, or in any public cloud. VMware is working to optimize Spring-based application deployment into VMware Virtualized cloud environments, but will continue to support full customer choice of deployment destinations. Finally, we are also looking to deliver virtual appliances for common, core IT services that should just be available and reliable in any cloud environment. IT should not be spending valuable resource time on managing these services, so we are making it dramatically simpler through our virtual appliance offerings. Again, these will run in the private cloud inside the enterprise, on VMware Virtualized public clouds, or other public cloud offerings.
了解vCloud Director 架构将帮助实施战略和安装vCloud Director 安装一个vCloud Director是由一个或多个主机组成。每个主机上运行的一组服务被称为vCloud Director Cell。集群中的所有主机共享一个单一的vCloud Director数据库。vCloud Director是横向扩展应用,因此,如果您需要随时增加容量,你可以简单地添加额外的Cell,并把一个负载平衡器放在前面来分担整个负载量在整个Cell上。我们将讨论更多关于多cell环境在后面的模块。Cloud Director Web控制台提供了访问vCloud Director的用户界面为所有的系统管理员和用户。vCloud Director Web控制台连接到负载平衡器的IP地址,它们转发到相应的cell。“vCloud API是一个开放的,基于REST的API,允许脚本访问云资源的消耗,如vApp上传/下载,目录管理等操作。该vCloud API使云层之间使用开放虚拟化格式(OVF),它保存应用性能,网络配置,以及其他可能的基本设置转移。vSphere的计算资源提供的vCloud主任。vCenter Server和ESX / ESXi主机的管理使用vSphere客户端。VShield Edge是vCloud主任的重要组成部分。Vshield Edge要求一个VShield Manager设备将在每个vCenter Server的提供云资源的含义每个vCenter服务器进入vCloud主任进口必须有一个相关的VShield管理器中可用。"扣款的vCenter集成与vCloud主任。的vCenter扣款服务器会谈到它自己的数据库,vCenter Server数据库和vCloud主任数据库,以便对与云费用协会和产生的使用和结算报告,使计算出有多少公司需要收取根据其对云的使用资源。”
