Introduction to the federal cloud computing strategy

Abstract

In this chapter, the Federal Cloud Computing Strategy is introduced, followed by a brief history of information technology (IT) within the US federal government beginning with the mainframe and concluding with the transition to mobility. A chronicle of the major IT-related legislation and policies provide insight into the governance of federal IT policies that have been developed over time to address governance, IT management, information security, security and privacy issues with the adoption of new technologies within the federal government. It further presents the federal IT transformation through a summary of the Federal Cloud Computing Strategy beginning with the drivers for adoption and ending with the application of the decision framework for cloud migration.

Introduction

In February 2011, the former US Chief Information Officer (CIO), Vivek Kundra, published the Federal Cloud Computing Strategy, herein referred to as the “Cloud Strategy.”¹

The Cloud Strategy, as illustrated in Fig. 1.1, was one of six major components of the 25 Point Implementation Plan to Reform Federal Information Technology Management, the US CIO’s roadmap to the cloud. The roadmap focused on shifting to cloud services, which can be deployed rapidly, and shared solutions that will result in substantial cost savings, allowing federal agencies to optimize spending and to reinvest in their most critical mission needs [1].

Figure 1.1 25 Point implementation IT reform plan—“Roadmap to the Cloud.”

In the 25 Point Implementation Plan to Reform Federal Information Technology Management, the Cloud First policy, also referred to as “Cloud First,” requires federal agencies to implement cloud-based solutions whenever a secure, reliable, and cost-effective cloud option existed. The publication of the Cloud Strategy facilitates the implementation of the Cloud First policy by initiating a program² to “accelerate the safe and secure adoption of cloud computing across the government” [2]. Additionally, the Cloud Strategy directs the National Institute of Standards and Technology (NIST) to lead the standards development³ related to security, interoperability, and portability, to reduce barriers to cloud adoption by federal agencies.

In the Cloud Strategy, the US federal government’s strategic approach for the adoption of cloud computing technologies was described, including the potential benefits, considerations, and trade-offs [2]. The strategy also provided a decision framework⁴ for federal agencies to use in outlining their plan for using cloud computing services. The migration plans and government-wide initiatives help identify candidate cloud services to improve their efficient use of IT investments to support their missions by leveraging shared infrastructures and economies of scale. The decision framework focused on changing how federal agencies approached the acquisition and use of IT⁵ and how they could effectively integrate cloud services into their IT portfolio.

The Cloud Strategy also established a set of basic principles and guidelines through which decision-makers within federal agencies could use it to accelerate their secure adoption of cloud services. Through the strategy, federal agencies were empowered with the responsibility for making their own decision on “what” and “how” to migrate to the cloud in support of the government-wide Cloud First policy. The Cloud First policy creates the momentum for federal agencies to proactively adopt cloud computing services by requiring them to begin with the selection of three⁶ “cloud-ready”⁷ IT services.⁸ To assist federal agencies in acquiring (procuring)⁹ cloud services to meet the Cloud First policy, the US General Services Administration (GSA) through the Cloud Computing Services (CCS) Program Management Office (PMO), established contracts that federal agencies could leverage for purchasing commodity cloud services. As depicted in Fig. 1.2, Email as a Server (EaaS)¹⁰ a commodity cloud service, was one of the most common types of IT systems migrated to the cloud.

Figure 1.2 Total number of systems migrating to the cloud by type.

In the section, the Decision Framework for Cloud Migration, a three-step framework described the foundational elements that were identified as being necessary for building a successful cloud migration plan.¹¹ In addition, the Cloud First policy gave federal agencies the opportunity to exercise their migration plans¹² and develop and share “lessons learned” from their experiences. The Cloud First policy also established the requirement for a program¹³ to be developed that would encourage Cloud Service Providers (CSPs) to meet federal security and privacy requirements through the development of “government-ready” (or FedRAMP compliant¹⁴) cloud services.¹⁵

The federal government has started the shift, from a traditional, asset-based model focused on acquiring IT, to a service (or utility¹⁶)-based model, focused on consuming IT services. Cloud computing was not only a change in the technology used by federal agencies, but also a cultural change.¹⁷ The “shift” towards cloud services required federal agencies to change the people and processes that are needed for procuring and provisioning cloud services. Cloud computing places an increased importance on how technology is planned, selected, and integrated.¹⁸ The new service-based approach to IT required federal agencies to learn how to manage services rather than assets. To effectively provision cloud services so that there can be an achieved optimization of resources, federal agencies had to link the benefits of cloud computing to their IT strategic plans.¹⁹ In addition, federal agencies also had to establish new IT governance processes and practices to ensure the adoption of secure cloud services adhered to the federal information security and privacy requirements.

Note

Importance of Federal IT Strategic Planning in the Adoption of Cloud Computing

Government-wide IT strategic planning for information and IT management has been highlighted as a systematic challenge almost since federal agencies began using IT. As early as 1960,²⁰ the US General Accounting Office (GAO)²¹ “ … call(ed) attention to the need for more positive central planning of a long-range nature within the executive branch of the government to promote the maximum degree of efficiency, economy, and effectiveness in the administration and management of costly automatic data processing facilities” [3].

However, it was not until 1980²² that the management of federal IT authority was centralized within the federal government. The Office of Management and Budget (OMB) was given government-wide responsibility to “oversee the use of information resources to improve the efficiency and effectiveness of governmental operations to serve agency missions” [4]. Federal agencies were also required to designate a senior agency official (also known as the Agency CIO) to be responsible for information resource management (IRM)²³ at the department and agency level. As the government-wide IRM activities evolved, Agency CIOs were also given additional responsibilities in developing “strategic plans²⁴ for all [departmental and agency] information and information technology management functions” [5].

IT Strategic Plans²⁵ play an important role in the adoption of cloud computing specifically when planning the expected improvements in productivity, efficiency, and effectiveness. Agency CIOs will need to be more effective in aligning IT Strategic Plans with Agency Strategic Plans²⁶ that enable the development and monitoring of performance metrics used to evaluate the business value of cloud services. Therefore, the IT strategic planning process used by Agency CIOs will need to emphasize the establishment of criteria that are more focused on objectively and quantitatively measuring the benefits of the investment of cloud computing technologies across the department and agency.
