Cloud Storage Gateways NetApp Confidential 1 SUMMARY In this section, we will present the key observations and insights of the report, these will be elaborated at length in the rest of the report. 1.1 CLOUD GATEWAYS (Section 2) A cloud storage gateway can be defined as follows: Cloud storage gateway is a hardware or software based appliance located on your organization’s premises. It enables applications located in your local datacenter to access data over a WAN from external cloud storage. The applications continue to use iSCSI, CIFS, NFS protocols while the cloud storage gateway accesses data over the WAN using APIs such as SOAP or REST. Cloud gateways act as a bridge between enterprise data centers and storage that is resident in an external service provider, supporting the trend towards hybrid clouds. Why are gateways important for our customers? 1. Agile storage delivery a. Provide access to a elastic storage for enterprises with simpler and rapid provisioning 2. Lower infrastructure costs : a. Pay only for storage used (pay-as-you-go model). b. Lower capital costs in the data center. c. Reduced storage management, offloaded to the cloud provider. d. No separate off-site disaster recovery solution needed. Why are gateways important for NetApp? 1. Another storage tier offering with different SLA properties in our storage portfolio. a. Cloud storage is viewed as low-SLA storage. A cloud gateway can enhance the value of cloud storage for enterprises – features like security, dedupe, storage mgmt., etc. 2. Opportunity to offer MSEs a compelling alternative to dedicated backup appliances (e.g. Data Domain). 1.2 RATIONALE FOR CLOUD GATEWAYS (section 2.3 ) Enterprise backups, archival data and tape data can leverage elastic cloud storage: o Roughly three copies of primary data are created for backup and secondary purposes leading to provisioning issues. o Cloud storage in a remote data center can be an equivalent for off-site tape (for DR). o Storage in the cloud is the largest growing cloud service (750 Billion objects in S3 by late 2011). Mainly archival and online backups from consumer space. o Movement of enterprise data can be facilitated by the advent of cloud gateways. All enterprise applications might not move to the cloud: o Migration of compute and storage to the cloud is not cheap unless the application is offered as a SaaS (Software as a Service) (e.g. Salesforce.com, Microsoft‟s Office365). o Security, control and process concerns for many larger enterprises will force them to keep at least some applications on-premises. o On-premise enterprise applications can benefit from elasticity and other cloud storage advantages via cloud gateways. Cloud Storage Gateways NetApp Confidential 1.3 KEY CLOUD GATEWAY USE CASES (Sections 3, 4, 5) Short term (1-2 yrs): Conduit for secondary storage - backup streams, archival data and tape data. Longer term (2-5 yrs): Conduit for primary Tier-2 application data (primary) – Microsoft Exchange, Microsoft SharePoint, Home directories. 1.4 OPPORTUNITIES AND THREATS FOR NETAPP (Section 7) Threat: Tier-2 application primary data, especially in virtualized environments form the bulk of our revenue. They can move to the cloud via cloud gateways impacting our revenue significantly. Amazon‟s AWS gateway suggests that their next version will aim at primary enterprise data. Opportunity-1: Currently NetApp does not have a compelling solution against DataDomain‟s backup appliances. A cloud gateway solution with inline deduplication, WAN latency performance optimizations, integrated with NetApp data management features (like SnapVault, Sync Mirror) allows us to compete with them in this $2.18B market. Opportunity-2: Cloud gateways can enable easier migration of data to cloud service providers who use NetApp storage. In addition, an integrated solution between a NetApp-based cloud storage and NetApp cloud gateway can be efficient and compelling. 1.5 KEY COMPETITORS IN THIS SPACE (Section 6) Startup vendors: Nasuni (primary focus), StorSimple (Sharepoint integration), Panzura (Global file system), CTERA (consumer oriented). Enterprise readiness is a question with most of them, only a couple of them have more than 50 customers. Established vendors: Amazon AWS Gateway, Riverbed‟s Whitewater appliance, Microsoft Azure appliance. Amazon‟s gateway as well as Google‟s foray into cloud storage highlight the fact that established players are keen to move entreprise data to the cloud. EMC has partnerships with almost all gateway vendors. EMC also has Atmos for cloud storage. Mode of deployment: All have VSAs, some have both VSAs and physical appliances. Very few have HA capabilities. 1.6 NETAPP ADVANTAGES/DISTINGUISHING FEATURES (Section 8) NetApp’s data management value: Expose NetApp‟s value add in data management (like snapshots, cloning, mirroring, snapvault) on another storage tier - cloud storage. SLO-based management: Enable migration of data between traditional storage tiers and cloud storage via SLOs. Leverage NetApp technologies: Cloud gateways require write-back caching for performance, NetApp can leverage existing technologies to create an efficient write-back cache that is protected by HA. 1.7 KEY ADDITIONAL IP FOR A CLOUD GATEWAY VIS-À-VIS NETAPP (SECTION 9) Basic cloud gateway infrastructure (for both secondary and primary storage): o File to object protocols conversion. o Volume to objects/group of objects data granularity mapping. o Security of objects in the cloud (encryption). Cloud Storage Gateways NetApp Confidential Value-added features (for both secondary and primary storage): o Compression o Deduplication o Application integration. o Cloud-aware data management (like auditing cloud costs) Optimizations for a viable primary specific storage solution: o WAN latency optimization via read and write back caching, pre-fetching Infrastructure for global collaboration of a primary storage repository: o Global Locking across a WAN. 1.8 RECOMMENDATIONS FOR NETAPP (Section 9, Section 10) BUY : (Near Term – 1 yr) o Pros: Lower time to market; compelling and unique IP (as listed above in Section 1.7). o Cons: Enterprise readiness of many startup vendors; Integration of acquired vendor‟s IP with NetApp data management features requires time and effort. o Recommendation: Buy only when IP is hard to develop; chart out pathway to integrate. PARTNER : (Short Term – 3 to 6 months) o Pros: Lower time to market; parity with EMC; integrated solutions that lower TCO. o Cons: Limited gains; NetApp‟s data management value-add could be hidden BUILD : (Long Term – 2 yrs) o Pros: NetApp‟s distinguishing features can be fully leveraged; enterprise readiness o Cons: Building cloud gateway in ONTAP would take beyond 2015 (LB+). Building non- ONTAP solution might limit exposing our value-adds. The overall recommendation is to partner immediately with cloud gateway vendors and pursue the „buy‟ and „build‟ options in parallel. Specific projects in the „build‟ option are outlined below: Enhance our V-series offering to have a cloud storage backend (already underway) ATG Projects: o Understand the performance of primary, Tier-2 applications on a cloud gateway o Reliability and security aspects of cloud gateway o Unique data management functionality required for cloud gateways o Global file system using cloud gateways Cloud Storage Gateways NetApp Confidential 2 INTRODUCTION The growth of cloud technologies, both public and private clouds, have been driven primarily by perceived reduction in IT costs. The commoditization of server hardware resources (especially CPU cycles, memory capacity and disk capacity) has been the
