Roadmap about migration of public services into the cloudA step by step roadmap for Public Authorities to help them as they plan, determine effort and budget, select the appropriate services, make the required internal organisational changes and finally execute the migration into cloud.
Cloud development model & technologies
Cloud computing can be classified on the basis of the targeted service and its perspective use (Zhang et al., 2010; Seo et al., 2014) in four main types: public clouds, private clouds, hybrid clouds and community clouds (APPTIS, 2010; Mell and Grance, 2011). The different deployment models are: Public clouds, Private clouds, Hybrid clouds, Community Cloud. While identifying the right cloud development model, one has to examine multiple issues such as security, performance requirements, types of data handled, IT skills required, long-term costs etc.
When choosing a specific cloud deployment model, it comes down to a series of trade-offs related to cost, management and security. While public clouds may be the best option for small organisation from a cost perspective, organizations that require more control and/or security may opt for a private or hybrid cloud — providing they have the manpower and budget to manage those deployments effectively.
ADOPT OPEN TECHNOLOGIES
Systems composed of open technologies provide the freedom to change environments and deliver a robust and secure experience, extending existing IT to the cloud. The majority of existing cloud offerings are implemented in proprietary and highly standardized form. Embracing an open cloud means providers don’t dictate technologies and that competition is embraced.
Examples of open technologies include Openstack, Cloud Foundry, Docker, LAMP, MySQL etc.
