Ten Considerations for a Cloud Procurement
Abstract
Cloud procurement presents an opportunity to reevaluate existing procurement strategies so you
can create a flexible acquisition process that enables your public sector organization to extract the
full benefits of the cloud. Cloud procurement considerations are key components that can form the
basis of a broader public sector cloud procurement strategy. This paper presents the top 10 cloud
procurement considerations for the public sector.
Abstract 1
Ten Considerations for a Cloud Procurement AWS Whitepaper
Introduction
Amazon Web Services (AWS) offers scalable, cost-efficient cloud services that public sector
customers can use to meet mandates, reduce costs, drive efficiencies, and accelerate innovation.
The procurement of infrastructure as a service (IaaS) cloud is unlike traditional technology
purchasing. Traditional public sector procurement and contracting approaches that are designed to
purchase products such as hardware and related software can be inconsistent with cloud services
(like IaaS). A failure to modernize contracting and procurement approaches can reduce the pool of
competitors and inhibit customer ability to adopt and leverage cloud technology.

Cloud procurement considerations
Cloud procurement presents an opportunity to reevaluate existing procurement strategies so you
can create a flexible acquisition process that enables your public sector organization to extract the
full benefits of the cloud. The following procurement considerations are key components that can
form the basis of a broader public sector cloud procurement strategy.
Understand why cloud computing is different
Hyper-scale Cloud Service Providers (CSPs) offer cloud services at massive scale and in the same
way to all customers. Customers tap into standardized commercial services on demand. They pay
only for what they use.
The standardized commercial delivery model of cloud computing compared is fundamentally
different from the traditional model for on-premises IT purchases (which has a high degree of
customization and might not be a commercial item). Understanding this difference can help you
structure a more effective procurement model. IaaS cloud services eliminates the customer’s
need to own physical assets. There is an ongoing a shift away from physical asset ownership
toward on-demand utility-style infrastructure services. Public sector entities should understand
how standardized utility-style services are budgeted for, procured, and used and build a cloud
procurement strategy that is intentionally different from traditional IT—designed to harness the
benefits of the cloud delivery model.
Plan early to extract the full benefit of the cloud
A key element of a successful cloud strategy is the involvement of all key stakeholders
(procurement, legal, budget/finance, security, IT, and business leadership) at an early stage. This
involvement ensures that the stakeholders can understand how cloud adoption will influence
existing practices. It provides an opportunity to reset expectations for budgeting for IT, risk
management, security controls, and compliance. Promoting a culture of innovation and educating
staff on the benefits of the cloud and how use cloud technology helps those with institutional
knowledge understand the cloud. It also helps to accelerate buy-in during the cloud adoption
journey.

Avoid overly prescriptive requirements
Public sector stakeholders involved in cloud procurements should ask the right questions in order
to solicit the best solutions. In a cloud model physical assets are not purchased, so traditional
data center procurement requirements are no longer relevant. Continuing to recycle data center
questions will inevitably lead to data center solutions, which might result in CSPs being unable
to bid, or worse, lead to poorly designed contracts that hinder public sector customers from
leveraging the capabilities and benefits of the cloud.
Successful cloud procurement strategies focus on application-level, performance-based
requirements that prioritize workloads and outcomes, rather than dictating the underlying
methods, infrastructure, or hardware used to achieve performance requirements. Customers can
leverage a CSP’s established best practices for data center operations because the CSP has the
depth of expertise and experience e in offering secure, hyper-scale, IaaS cloud services. It is not
necessary to dictate customized specifications for equipment, operations, and procedures (e.g.,
racks, server types, and distances between data centers). By leveraging commercial cloud industry
standards and best practices (including industry-recognized accreditations and certifications),
customers avoid placing unnecessary restrictions on the services they can use and ensure access to
innovative and cost-effective cloud solutions.
Separate cloud infrastructure (unmanaged services) from
managed services
There is a difference between procuring cloud infrastructure (IaaS) and procuring labor to utilize
cloud infrastructure or managed services, such as Software as a Service (SaaS) cloud. Successful
cloud procurements separate cloud infrastructure from hands-on keyboard services and labor, or
other managed services purchases. Cloud infrastructure and services, such as labor for planning,
developing, executing, and maintaining cloud migrations and workloads, can be provided by CSP
partners (or other third parties) as one comprehensive solution. However, cloud infrastructure
should be regarded as a separate service with distinct roles and responsibilities, service level
agreements (SLAs), and terms and conditions.
Incorporate a utility pricing model
To realize the benefits of cloud computing you need to think beyond the commonly accepted
approach of fixed-price contracting. To contract for the cloud in a manner that accounts for
fluctuating demand, you need a contract that lets you pay for services as they are consumed.
Avoid overly prescriptive requirements 4

CSP pricing should be:
Offered using a pay-as-you-go utility model, where at the end of each month customers simply
pay for their usage.
Allowed the flexibility to fluctuate based on market pricing so that customers can take
advantage of the dynamic and competitive nature of cloud pricing.
Allowing CSPs to offer pay-as-you-go pricing or flexible pay-per-use pricing gives customers
the opportunity to evaluate what the cost of the usage will be instead of having to guess their
future needs and overprocure. CSPs should provide publicly available, up-to-date pricing and
tools that allow customers to evaluate their pricing, such as the AWS Pricing Calculator: https://
calculator.aws/#/. Additionally, CSPs should provide customers with the tools to generate detailed
and customizable billing reports to meet business and compliance needs.
CSPs should also provide features that enable customers to analyze cloud usage and spending so
that customers can build in alerts to notify them when they approach their usage thresholds and
projected/budgeted spend. Such alerts enable organizations to determine whether to reduce usage
to avoid overages or prepare additional funding to cover costs that exceed their projected budget.
Leverage third-party accreditations for security, privacy, and
auditing
Leveraging industry best practices regarding security, privacy, and auditing provides assurance
that effective physical and logical security controls are in place. This prevents overly burdensome
processes and duplicative approval workflows that are often unjustified by real risk and compliance
needs. There are many security frameworks, best practices, audit standards, and standardized
controls that cloud solicitations can cite, such as the following:
Federal Risk and Authorization Management Program (FedRAMP)
Service Organization Controls (SOC) 1/American Institute of Certified Public Accountants
(AICPA): AT 801 (formerly Statement on Standards for Attestation Engagements [SSAE] No. 16)/
International Standard on Assurance Engagements (ISAE) 3402 (formerly Statement on Auditing
Standards [SAS] No. 70), SOC 2, SOC 3
Payment Card Industry Data Security Standard (PCI DSS)
International Organization for Standardization (ISO) 27001, ISO 27017, ISO 27108, ISO 9001
Department of Defense (DoD) Security Requirements Guide (SRG)
Leverage third-party accreditations for security, privacy, and auditing 5

Federal Information Processing Standard (FIPS) 140-2
Understand that security is a shared responsibility
As cloud computing customers are building systems on a cloud infrastructure, the security and
compliance responsibilities are shared between service providers and cloud consumers. In an IaaS
model, customers control both how they architect and secure their applications and the data they
put on the infrastructure. CSPs are responsible for providing services through a highly secure
and controlled infrastructure and for providing a wide array of additional security features. The
respective responsibilities of the CSP and the customer depend on the cloud deployment model
that is used, either IaaS, SaaS, or Platform as a Service (PaaS).Customers should clearly understand
their security responsibilities in each cloud model.
Design and implement cloud data governance
Organizations should retain full control and ownership over their data and have the ability
to choose the geographic locations in which to store their data, with CSP identity and access
controls available to restrict access to customer infrastructure and data. Customers should clearly
understand their responsibilities regarding how they store, manage, protect, and encrypt their
data. A major benefit of cloud computing as compared to traditional IT infrastructure is that
customers have the flexibility to avoid traditional vendor lock-in. Cloud customers are not buying
physical assets, and CSPs provide the ability to move up and down the IT stack as needed, with
greater portability and interoperability than the old IT paradigm. Public sector entities should
require that CSPs: 1) provide access to cloud portability tools and services that enable customers
to move data on and off their cloud infrastructure as needed, and 2) have no required minimum
commitments or required long-term contracts.

Specify commercial item terms
Cloud computing should be purchased as a commercial item, and organizations should consider
which terms and conditions are appropriate (and not appropriate) in this context. A commercial
item is recognized as an item that is of a type that has been sold, leased, licensed, or otherwise
offered for sale to the general public and generally performs the same for all users/customers,
both commercial and government. IaaSCSP terms and conditions are designed to reflect how a
cloud services model functions (i.e., physical assets are not being purchased, and CSPs operate
at massive scale to offer standardized commercial services). It is critical that a CSP’s terms and
conditions are incorporated and utilized to the fullest extent.
Define cloud evaluation criteria
Cloud evaluation criteria should focus on system performance requirements. Select the appropriate
CSP from an established resource pool to take advantage of the cloud’s elasticity, cost efficiencies,
and rapid scalability. This approach ensures that you get the best cloud services to meet your
needs, the best value in these services, and the ability to take advantage of market-driven
innovation. The National Institute of Standards and Technology (NIST) definitions of cloud benefits
are an excellent starting point to use for determining cloud evaluation criteria: Cloud Computing

Technology.
