3 Cloud Computing—the Path to Increased Efficiencies and Cost Savings for Government Agencies
1 Adoption of Cloud Computing Escalates
Government agencies—federal, state, and local—are evaluating the move to cloud technology
deployments due to the many economic and technical benefits. Scalable on-demand cloud-computing
services extend the advantages of virtualization and shared services, positioning agencies to quickly
respond to changing business requirements with an efficient, flexible IT infrastructure.
U.S. Federal Government
Federal agencies have been under a “cloud-first” mandate from the White House since the fall of 2009 to
achieve operational efficiencies by adopting "light" technology and shared services. However, obstacles
such as data protection and performance need to be addressed before moving confidential information
outside an agency-dedicated IT environment. Once preventive measures have been taken, it is easier for
agencies to adopt a full cloud approach for their organizations.
State and Local Government
Many state and local agencies are also following the move to private- and public-cloud models to
increase efficiencies and save tax dollars. A cloud infrastructure streamlines the way technology is used
to deliver services, resulting in the ability to quickly provision servers and storage at a lower cost.
1.1 Different Cloud Models Support Different Business Objectives
Deciding which cloud model offers the best fit depends on the critical nature of the workload and how
security and compliance requirements will be handled. Whether a cloud is public, private, or a hybrid, the
key to success is creating an appropriate infrastructure in which all resources can be efficiently utilized
and shared. And in a cloud environment, implementing the right data storage model becomes even more
crucial to effectively support the requirements of a shared infrastructure model.
Figure 1) Cloud-computing models.
Private Cloud
Private clouds are about IT flexibility, efficiency, and cost savings. With a services delivery model, IT can
offer services to its internal customers from a service catalog, automate processes, meter usage, create
showback or chargeback models, and deliver services for greater cost savings, utilization, and
efficiencies.

4 Cloud Computing—the Path to Increased Efficiencies and Cost Savings for Government Agencies
According to a recent CIO study1, the top benefits expected from moving to a private cloud business
model include increased IT efficiencies/lowered costs, less downtime/planned outages, improved SLAs,
and more reliable security.
Private clouds, which are dedicated to an agency for use by its internal organizations behind the firewall,
provide an excellent cloud-computing model in which maintaining applications and data internally is the
driving business factor. Through private clouds, agencies can:
Deliver resources on demand. Internal organizations and users can securely access pools of shared resources immediately without compromising data protection.
Automate the provisioning process. Self-service portals can be created to allow internal groups to request and receive access to IT resources with minimal IT support, saving time and money while speeding time to market with innovative new services. When projects are completed, shared resources can be reallocated, eliminating overprovisioning.
Make informed decisions. IT can easily monitor and analyze which departments use specific resources to define and meet internal SLAs, optimize IT service catalogs, and make more insightful business decisions.
Figure 2) Private cloud benefits.
Public Cloud
For many agencies, the potential cost benefits of procuring cloud services from service providers are the
driving force. In the CIO study mentioned earlier, respondents expected to realize the ability to buy and
use resources on a per-need basis, scale up and down to meet variable workloads, and reduce
provisioning time by moving to a public cloud business model. By acquiring cloud services from service
providers to manage specific workloads, such as messaging or disaster recovery, agencies can move
from a capex to an opex model, enhance efficiencies, provide IT on demand, and accelerate time to
market with new agency services. However, initial service provider selection and planning are critical to
obtaining ROI from an outsourced model.
Accelerate time to market with on-demand infrastructure.
Streamline administrative tasks by outsourcing noncore applications.
Reduce IT capital requirements with a pay-as-you-go expense model.
Improve data protection with disk-based backup and disaster recovery.
Leverage reliable and secure cloud services through NetApp partners.
To facilitate the evolution to the cloud, NetApp has developed a global network of world-class service
provider partners who deliver a comprehensive portfolio of cloud services built on NetApp® technology.

5 Cloud Computing—the Path to Increased Efficiencies and Cost Savings for Government Agencies
Hybrid Cloud
An emerging cloud option that offers many of the benefits but does not require moving all of an agency’s
information to a cloud infrastructure is known as a “hybrid cloud.” The hybrid cloud combines the
availability, performance, agility, and control of the agency’s storage with the highly reliable, scalable, and
low-cost infrastructure of the cloud. This model can provide the best of both worlds—agencies are able to
compute in the cloud and store on the premises. By using self-service, on-demand, elastic, and
showback/chargeback models, agency IT managers can have their data under their complete control,
relieving the stress associated with security, storage, and regulatory requirements.
2 NetApp Cloud Technologies
When it comes to storage for cloud computing, NetApp is a preferred technology partner, whether your
agency is building a private cloud infrastructure, working with a system integrator, or outsourcing to cloud
service providers. NetApp offers superior technology to meet cloud requirements combined with
established solutions and partnerships such as those with Terremark (procuring telecom as a service)
and DLT Solutions (for storage as a service).
NetApp offers the infrastructure for any type of cloud that best fits an organization’s needs. From storage
as a service to a traditional infrastructure in a data center to utilizing private and public resources, NetApp
has the options to help any agency successfully make the transition to the cloud. There are multiple paths
to the cloud, all with the goal of maximizing capacity utilization, improving IT flexibility and
responsiveness, and minimizing cost. Whatever type of storage you need, NetApp can deliver.

2.1 Superior Storage for Cloud Computing
NetApp’s unified storage approach can eliminate the need for agencies to buy different storage systems
to support different needs, such as one storage system for high-end SAN, another for NAS, and another
for archive and compliance. The entire NetApp FAS storage family runs a single operating environment:
the Data ONTAP® operating system. All agency storage needs are met with the same hardware,
software, staff, and processes to achieve the efficiencies and cost savings of cloud computing. The ease
of management inherent in NetApp storage can actually reduce operator errors, which are now a major
cause of system downtime.
• NetApp Unified Storage Architecture. NetApp’s cloud-enabling technologies are built on the
NetApp Unified Storage Architecture and the NetApp Data ONTAP operating environment, a flexible
architecture that supports many applications, multiple protocols, diverse workloads, and changing
6 Cloud Computing—the Path to Increased Efficiencies and Cost Savings for Government Agencies
requirements. This unified set of tools and processes can help reduce complexity and costs by
leveraging existing infrastructure for current and future workloads as cloud solutions are built and
deployed.
• Nondisruptive operations. With the introduction of clustered Data ONTAP, agencies now have the
ability to provide their users with nondisruptive operations. They also have the ability to continuously
serve data even during maintenance and lifecycle operations as well as during unplanned failure
events. Data motion is transparent and nondisruptive to NAS and SAN hosts and FAS and V-Series
models, and it enables the storage infrastructure to continue serving data throughout these changes.
• Scalable and efficient shared IT infrastructure. Take advantage of the full range of NetApp storage
technologies for cloud computing, including built-in storage efficiency features; integrated data
protection; and the ability to scale up, scale down, and scale out to address dynamic resource needs.
• Unified management. NetApp Data ONTAP combined with FAS and V-Series storage systems
provides massive scalability and performance. These systems not only provide fast provisioning for
additional capacity, but they also deliver proven reliability (99.999% availability) and embedded
security of agency data, meeting regulatory requirements for document retention.
2.2 Secure Multi-tenancy
Traditionally, providing the highest level of data isolation and security has meant independent storage
hardware. Security in both private and public clouds must be as tight as possible without sacrificing
efficiency. With NetApp software, agencies can share storage with maximum privacy and data security.
NetApp MultiStore® software allows multiple, separate, and private virtual storage controllers to be
created on a single storage system, allowing storage to be shared with minimum impact on privacy or data security. The result is secure multi-tenant cloud storage with increased storage utilization. With MultiStore, storage can be provisioned, moved, and protected based on user-defined boundaries; virtual storage controllers allow appropriate policies to be applied to each container, which can correspond to a particular application or client of a cloud service.
In addition, NetApp with Cisco and VMware helps provide secure end to-end multi-tenancy across applications and data, allowing agencies to reap all the benefits and business advantages of a shared IT infrastructure for private cloud computing.

2.3 Service Automation and Management
NetApp offers a suite of management products to efficiently manage storage capacity in a shared
infrastructure—from policy-based automation to end-to-end cloud management tools from NetApp and
our partners. And our open management strategy simplifies third-party or in-house tools integration with
NetApp management products.
NetApp OnCommand® data management software offers effective, cost-efficient management of shared
storage infrastructures to help optimize utilization, meet SLAs, minimize risk, and boost performance.
Reduce complexity using a single, unified storage management approach.
Automate workflows to optimize storage efficiency and minimize IT spend.
Extend data management and service delivery with an open integration model.
Simplify storage operations by automating all tasks associated with storage so you can manage more capacity with fewer resources while increasing operational efficiency.
Policy-based automation maps end-user requirements to specific levels of service.
Once policies are established, new storage consumers (for a new application, within a business unit, and
so on) can request and receive storage and automatically get the appropriate level of data protection and
other services without manual intervention. Through API and web services, NetApp data management
solutions can be integrated into orchestration systems to create end-to-end cloud management solutions.
Figure 4) Achieve storage and service efficiencies across cloud infrastructure with NetApp OnCommand.
2.4 Integrated Data Protection
The traditional approach to data protection is expensive and inflexible. Many data centers keep two full
data copies plus incremental backups stored in backup formats that are only useful for recovery. NetApp
takes a different approach to data protection, one that is more efficient and leaves data in a format in
which it can be leveraged for other purposes.
NetApp provides fully integrated and comprehensive data protection and disaster recovery based on
mature technologies that include NetApp Snapshot™
, SnapVault®, the SnapManager
® Suite, SnapMirror
®,
MetroCluster™
, and Protection Manager technologies. These technologies off-load the burden of data
protection from servers to storage, providing a consistent approach to data protection across a cloud
infrastructure while allowing utilization of backup and disaster recovery data for development or other
activities. The result is an efficient data protection infrastructure that protects availability and reduces risk.

4 Hybrid Cloud Solution
The concept of computing in the cloud and storing on the premises offers the agility of cloud computing
with the advantages of data residing on enterprise storage. Storing on the premises allows NetApp Snap
features, such as backup/restore and disaster recovery, which are essential to meeting SLAs that are in
place. For computing requirements that need a blended model, NetApp works with a variety of partners to
address computing initiatives across agencies that require both on-premise and public cloud components.
Examples of mixed-mode models are described in the following sections.
4.1 Combine on-Premise FlexPod with Public Cloud Capabilities
NetApp service providers such as Verizon/Terremark, AT&T, and Virtustream have proven enterprise
cloud-computing solutions that leverage NetApp storage to deliver superior agility and control for
government agencies. Agencies benefit from the ability to seamlessly extend new and legacy
infrastructure to create a compelling hybrid model for their IT systems.
By combining FlexPod with enterprise-class cloud-computing services from NetApp authorized service
providers, agencies can deploy a single infrastructure with a logical split between private and public
infrastructure that effectively scales on-premise infrastructure components while benefiting from compute-
in-the-cloud efficiencies. Agencies can consolidate resources and data where it makes sense, and retain
control over data and components to support security requirements, encryption, or policies that dictate
physical infrastructure.

4.2 NetApp Private Storage for Amazon Web Services
NetApp Private Storage for Amazon Web Services (AWS) allows government agencies to build a flexible
cloud infrastructure that balances both private and public cloud resources to optimize business outcomes.
The solution combines dedicated NetApp private storage with Amazon’s elastic cloud compute resources
for on-demand performance computing. This allows agencies to leverage cloud-computing services while
retaining full control and mobility of agency data. With this approach, agencies can:
Increase agility using a mix of on-premise and cloud resources.
Maintain control, compliance, and mobility of agency data.
Gain enhanced data protection and business continuity at a lower cost.
Improve efficiencies for a variety of performance workloads.
Access big data analytics at a significant savings compared to running big data analytics on the premises.
Support high-performance enterprise applications in the cloud.
This concept of computing in the cloud and storing on the premises offers the agility of cloud computing
with the advantages of data residing on private storage. Storing on the premises allows Snap features,
such as restoring and disaster recovery, and those features are essential to meet SLAs that are in place.
4.3 Storage as a Service
Government agencies are under tremendous pressure to keep pace with exponential data growth.
Inflexible storage infrastructures and tightening budgets make it difficult to quickly respond to changing
business requirements.
Storage as a service is an enterprise-class hardware, software, and services solution that combines
secure, available, and dedicated on-premise infrastructure with a variable pay-as-you-go model without
capital investment. Companies like DLT and VION have NetApp certified storage experts who understand
the agency’s storage infrastructure needs, assess the current environment, and then design a specific
solution that fulfills the agency’s needs. After the systems have been implemented, agencies are only
charged for the storage capacity they actually consume.
4.4 Financing Flexibility
NetApp Capital Solutions is another resource government agencies can leverage if they need financial
flexibility. NetApp Capital Solutions helps reconcile two commonly opposing objectives: lowering capital
expenditures and continuing to invest in innovation. NetApp data storage solutions reduce the total cost of
ownership (TCO) of your IT infrastructure, and NetApp Capital Solutions increases your financial
flexibility. By moving capital expenditure dollars normally used for storage purchases to operational
expenses, agencies can free up capital for mission programs or other expenditures. It enables scale-up
storage capacity fast, while aligning costs to storage utilization.
5 Selecting the Right Cloud Model
As cloud models continue to mature, government agencies are faced with many considerations when selecting the correct model to meet key business drivers. Regardless of the model you choose, having clear answers to the following questions will frame the potential for the success of your cloud decision.
Do you have a plan to save money? (If you have a problem out of the cloud, you will still have that problem in the cloud.)
What would you do with the resources that are now working on infrastructure? (It’s not just about the technology decision, but about people, too.)
10 Cloud Computing—the Path to Increased Efficiencies and Cost Savings for Government Agencies
Do you have people who are capable of managing your cloud program? Do those people have the right skills to manage SLAs?
Are you ready from a policy perspective?
How will it help your budget to shift from capex to opex?
What’s the worst-case scenario if you move to a cloud infrastructure and something goes wrong? Can you bear that?

Do you need the ability to scale storage resources but leverage the cost benefits of computing in the
cloud?
11 Cloud Computing—the Path to Increased Efficiencies and Cost Savings for Government Agencies
Do you need to cover gaps between old and new systems?
Are you looking to “test the water” with the cloud to better understand what makes sense for your
enterprise?
Does your enterprise require you to manage some data with some pockets highly sensitive and
others less so?
Do you require resource pooling that enables location-independent, multi-tenant access?
Do you want to seamlessly link your existing storage infrastructure to a more flexible cloud-computing
model?
