Providing a simple portal-based graphical solution, which allows their technical and non-technical vCD customers to easily backup and restore virtual applications is critical to the successful adoption of this type of offering. In addition, any portal-based Backup as a Service (BaaS) solution of this type must integrate into Service Provider orchestration, management, and portal infrastructures. In addition it must integrate into tenant portal infrastructures to enable a seamless Hybrid Cloud. Existing dedicated, standalone, disk-based or tape-based backup offerings dont provide the ease of use or deep integration with vCD that Service Providers require. Therefore, these solutions do not enable providers to offer differing levels of backup as a service to their customers. This enhanced capability being introduced in the Avamar 7.1 release accommodates service providers with the ability to offer backup services to all of their customers, regardless of their technical abilities or usage model. SOLUTION OVERVIEW This white paper describes a scalable solution to augment VMware vCloud Director environments with backup resources, including the backup components involved, as well as the associated portal and orchestration integration capabilities. This solution can be used to provide backup services for public or private cloud- based VMware vCloud Director environments. This white paper validates the integration of the solutions components and provides broad guidelines about how this type of solution can be built and integrated into the service providers environment. Key solution components include: EMC Avamar 7.1 to provide centralized and scalable backup environment with deduplication and replication capabilities. VMware vCloud Directorto orchestrate the provisioning of Software-Defined Data Center services as complete Virtual Data Centers that are ready for consumption in a matter of minutes. KEY RESULTS Backup as a Service enables service providers to fundamentally change the way in which they provide backup services for customers who have purchased their hosted vCloud Director environments. By leveraging industry leading backup and recovery resources that have been enhanced to integrate and augment into native ITaaS infrastructures such as VMwares vCloud, service providers can provide robust and uniform data protection capabilities and bring a truly differentiated service offering in the marketplace. The delivery of Avamar backup services for VMware in the Public Cloud is truly an enabling technology for Enterprise Cloud. This solution demonstrates that BaaS: Can provide a simple one-click backup experience Can be leveraged through direct or channel sales Improves flexibility and simplifies application deployment Enables users to focus on revenue generating activities and other projects instead of equipment logistics Figure 1: Avamar vCD services 5. 5 Audience This white paper is intended for EMC employees, partners, and customers including IT planners, system architects and administrators, and any others involved in evaluating, acquiring, managing, operating, or designing a BaaS infrastructure environment leveraging EMC technologies. Throughout this white paper we assume that you have some familiarity with the concepts and operations related to backup and virtualization technologies, and their use in cloud and data center infrastructures. INTRODUCTION Service providers can offer BaaS to customers who need a flexible, on-demand backup infrastructure, but prefer not to purchase, configure, or maintain it by themselves. In other cases, customers may have on premise backup resources in their private cloud, yet are looking for backup and recovery capabilities for public cloud resources they are consuming to augment on premise infrastructure. The features introduced in our latest release of Avamar, which our outlined here, focuses on demonstrating how a service provider can easily leverage Avamar to provide integrated and easy-to-consume backup and recovery resources in their vCloud Director services catalog. Fundamentally, as with any BaaS offering, this solution enables customers to consume data protection services in much the same manner as they consume compute, memory and storage resources today in vCD. The key is that users consume and pay for these resources without needing to understand or maintain the component devices and infrastructure required to provide the service. Furthermore, customers can draw on the elastic resources that cloud infrastructure delivers and pay only for the backup service they consume. The BaaS environment typically consists of: Hosted vCloud Director environments Self-service portal Secure multi-tenant-enabled shared infrastructure EMC AVAMAR OVERVIEW Developed to solve the challenges associated with traditional backup, EMC Avamar deduplication backup software and system, equipped with integrated global, client-side data deduplication technology, provide fast, next-generation daily full backups for virtual environments, NAS systems, desktops/laptops, remote offices and business critical applications. EMC Avamar reduces the size of backup data at the clientbefore it is transferred across the network and ultimately stored. Unlike traditional backup, Avamar delivers fast, daily full backups via existing IP networks, and makes recovery fast and easy with single-step restore. Avamar also deduplicates backup data globally across applications and sites worldwide to reduce the total required backup storage by up to 30x. As a result, Avamar provides the benefits of efficient long-term retention on disk while dramatically lowering capital and operating expenses including floor space, power, and cooling. Avamar backups can be quickly recovered in just one stepeliminating the hassle of restoring the last good full and subsequent incremental backups to reach the desired recovery point. Avamar software, similar to the other components in the Data Protection Suite, is integrated for multi-streaming backups to EMC Data Domain deduplication storage systems for efficient and highly scalable backup of specific data types and applications, simplifying management and maximizing existing IT investments. Avamar: Industry Leading Backup for VMware Figure 2: Avamar deduplication moves less data 6. 6 EMC Avamar provides variable-length client-side deduplication to accelerate the virtualization journey by providing extremely fast and efficient backup and recovery for the VMware environment. Avamar protects virtual machines (VMs) by deduplicating data at the clientso that only new, unique, sub-file, variable-length data segments are sent during daily full backups. This dramatically reduces the daily impact on the virtual and physical infrastructure by up to 99 percent as compared to traditional full-backup methods. While traditional backup software moves upward of 200 percent of the primary backup data on a weekly basis, Avamar moves as little as two percent over the same seven-day periodremoving backup bottlenecks and enabling even greater levels of virtualization. Avamar backs up data globally across physical and virtual servers. For virtualized environments, flexible backup options include guest- and image-level backups. Avamar is certified component of VCE VblockTM Systems and VSPEX converged infrastructure platforms. Avamar is tightly integrated to the vStorage APIs for Data Protection (VADP) for agentless backups. Deduplication and backup executes on a multi-threaded universal proxy VM, off-loading the backup from any of the VMs where the applications are running. Through vSphere, each VM is dynamically mounted to the proxy without physically moving data across the network, enabling Avamar to back up numerous virtual machines in just minutes. To maximize backup throughput, Avamar uses a load balancing algorithm across multiple proxy VMs. Instead of being locked into using only a single proxy for a set of VMs, Avamar leverages numerous proxies and sends a backup job to an available proxy. Avamar also takes advantage of VMwares Changed Block Tracking (CBT) to further speed up the backup and restore processes. VMware presents only changed blocks to the Avamar software, where each block is broken into variable length segments and further evaluated for uniqueness. Only the unique segments are sent for backup, achieving the fastest backup possible. Conversely, the restore process also leverages CBT for faster recovery. Avamar understands the current state of the VM and determines the required blocks from the last backup, restoring the VM in just minutes. Avamar enables full VM or file-level restore to the original VM, an existing VM or a new VMdirectly from the Avamar user interface. Also available with image backups is disk-level granularity that enables Avamar to back up specific virtual disks, thus reducing backup times and backup storage. Thin provisioned recovery speeds up the restore process and reduces required storage. EMC AVAMAR FOR VCLOUD DIRECTOR WORKFLOW OVERVIEW The following sections of this white paper will walk end to end through a typical service provider ITaaS model and how backup resource and policy creation, assignment, and consumption occurs within an Avamar powered vCloud Director protection solution. VMware vCloud Roles Before we dive into each process, lets review the specific administrator roles involved in a typical vCD workflow: Cloud Admin The cloud administrator and team manage the infrastructure and overall management of providing consumable services and provisioning those services for consumption by individual tenant orgs. In the case of an SP, each tenant would be a distinctly different client consuming ITaaS resources offered by the SP. As we will discuss further in the sections below, the cloud administration team will manage EMC Avamar systems as the foundation of Backup Resources included in new or existing tenant service catalogs. This includes allocation of underlying backup repositories to each vCD tenant, creating backup policy service-level templates, and enforcing resource usage quotas in those policies. Organization Admin The Organization Admin (Org Admin) plays a hybrid role within the vCD workflow. While acting as a consumer of resources provided and assigned by the SP, the Org Admin is also a provider and administrator of virtualized application (vApp) services to sub-tenants who are often the organizations lines of business admins. Within the vCD environment the Org Admin has full rights to manage and deploy the vApp instances control and rights are Figure 3: Avamar VM image backup 7. 7 limited and controlled by the policy SLAs delivered by the Cloud Admin. For backup resources, while the cloud admin instantiates backup policy templates into backup policies, the Org Admin can manipulate these polices, assign them as default to VDCs and assign them explicitly to vApps. Line of Business Admin The line of business admin (LOB Admin) is a pure consumer of the vApp resources provisioned by the Org Admin, and administers the business critical applications running on those vApp instances for end-users. Working together with the Org Admin to assure availability of applications for backup and recovery operations, LOB Admins have full control to run ad-hoc backups and recoveries as necessary to protect vApps as needed but have limited control and require collaboration with the Org Admin to set backup schedule and retention. Unlike other solutions offering protection for vCloud Director resources, Avamar natively integrates within vClouds Role-Based Access Control mechanisms to map access to backup and recovery resources and policies without the requirement for creating additional service accounts and access rights for each role within Avamar. Seamlessly applying backup and recovery services within the existing vCD workflow was a top requirement for development of this functionality. Backup Resource Mapping and Assignment As mentioned above, Avamar introduces through tight integration with vCD the ability to provision and assign backup resources to tenants and sub-tenants. Lets take a closer look at how physical infrastructure implemented via Avamar along with its integration with Data Domain systems can be incorporated and leveraged within vCD. The foundation of consumable backup resources is the Backup Appliance. A Backup Appliance can be an Avamar Data Store, Avamar Virtual Edition, or Avamar with one or more Data Domain systems. For the illustration shown in Figure 2 below, the process begins with the Cloud Administrator. A member of the cloud administration team is responsible, and is provided with the capabilities to manage all the backend backup appliances and corresponding physical infrastructure. As we begin working through the multi-tenant structure, the Cloud Admin creates Backup Repositories that have a Many:1 relationship to Backup Appliances. Using the Backup Repository abstraction, the pool of Backup Appliances can now be split amongst tenants who will consume their resources. While a r...
