FCW : November and December 2014
Platform as a service promises significant savings of both time and money. The biggest names in cloud comput- ing all offer PaaS solutions — as do countless providers that specialize in everything from mapping to content management to mobile app development. A few offerings already comply with the Federal Risk and Authorization Management Program, and a 2013 survey of federal IT professionals found that 95 percent believed their agen- cies would benefit from migrating to PaaS. So why is PaaS still mysterious to so many? Partly it’s been a matter of structure and security. Many of the most popular early PaaS solutions, such as Heroku and Engine Yard, were available only in the public cloud, limiting their practical appeal for most federal agen- Can PaaS carve out its place in the federal cloud? BY TROY K. SCHNEIDER Platform as a service offers obvious upsides, but agencies are still working through specific needs and uses FocusOn: PaaS SPECIAL PULLOUT SECTION November/December 2014 FCW.COM 1 The key question: What do you control? The lines between different categories of cloud services can be blurry, but here’s how the National Institute of Standards and Technology defines SaaS, PaaS and IaaS: Software as a service (SaaS) The capability provided to the con- sumer is to use the provider’s applications running on a cloud infrastructure. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, stor- age, or even individual application capabilities, with the possible exception of limited user-specific applica- tion configuration settings. Platform as a service (PaaS) The capability provided to the consumer is to deploy onto the cloud infrastructure applications created using programming languages, libraries, services, and tools supported by the provider. The consumer does not manage or control the underly- ing cloud infrastructure including network, servers, operating systems, or storage, but has control over the deployed applications and possibly configuration settings for the application-hosting environment. Infrastructure as a service (IaaS) The capability provided to the con- sumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or con- trol the underlying cloud infrastructure but has con- trol over operating systems, storage, and deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
