5.1.1. Public Cloud Brokerage Service DAS OIT is leading the effort to transform how IT services are delivered, maintained, and consumed in the State. A key outcome of this digital transformation is the development of cloud-based capabilities that will improve the quality of services, agility, and foster a culture of collaboration, accountability, and innovation. Within the Public Cloud Brokerage Service model, DAS OIT offers IaaS, PaaS, and vendor managed frameworks. These services are available on multiple public clouds: Microsoft Azure, Amazon Web Services, Oracle Cloud Infrastructure, Google Cloud Platform and IBM Cloud. The Cloud Smart Strategy requires any proposed customized applications3 running on an IaaS or PaaS public cloud from any of these providers to reside in the Brokerage Service. 5.1.1.1. IaaS Cloud Brokerage Service IaaS is the capability to provision processing, storage, networks, and other fundamental computing resources to deploy and run software, which can include operating systems and applications. The Customer does not manage or control the underlying cloud infrastructure but has control over the applications and databases. Depending on the domain, there could be limited control over selecting certain networking components (e.g., host firewalls). The goal of the IaaS Cloud Brokerage Service is to evaluate and provide the most optimal hosting environment in the State’s public and/or private clouds. In an IaaS scenario, the State would provision infrastructure assets, such as virtual servers, that are hosted in the State’s private or public cloud tenants. The Customer would then install operating systems and application software on that infrastructure and use it. IaaS Cloud Brokerage Service offers: • Configuring network security groups and backups; • Performing restores; • Storage; • Providing a direct network connection to the State of Ohio Computer Center from public cloud vendor locations; • Managing and monitoring using the same tools as the private cloud; • Patching of the operating system; • Cloud utilization / cost analysis; • Design consultation; • Education; and • Offering specific cloud expertise, when needed. Any activity at or above the middleware layer, including the application layer, is the responsibility of the Customer and is not covered under IaaS Cloud Brokerage Service. Please refer to the Cloud Services Responsibility Matrix above on page 6 for further details.
