Leveraging the Cloud Computing Benefits for Developing Economies
IBM’s cloud computing delivery model is structured to enable real-time delivery of configurable highly scalable computing resources over the internet to multiple organizations, enabling them to pay-per-use while eliminating the associated resources and cost to build and operate an infrastructure. IBM’s cloud delivery models have helped organizations scale their investments as they grow their business.
Economies of the developing countries continue to face challenges like energy shortages, floods, deprived law and order situations, and a host of other structural impediments, which have held back investment and growth in these countries. Small and medium-sized organizations are playing a vital role in these developing economies. According to Asia-Pacific Co-operation (APEC), small and medium-sized enterprises (SMEs) represent the backbone of the region’s economy, making up 90 percent of all businesses operating in the Asia-Pacific region. Despite this significant contribution, the SMEs still face many challenges and obstacles that prevent them from further expanding their businesses and obtaining sustainable growth. However, various models of cloud computing can be applied to address the challenges faced by the SMEs in establishing a reliable infrastructure as cloud computing has the potential to bring significant benefits.
This article explores various models of cloud services which can be beneficial to the small businesses by reducing the costs of investment.
Models of Cloud Services
The three common models of cloud services, software-as-a-service’ (SaaS), platform-as-a- service (PaaS) and infrastructure-as-a-service (IaaS), are explained below in detail:
• Cloud-based applications—or software as a service (SaaS)—run on computers “in the cloud” that are owned and operated by others. Users connect to them using their computers via the Internet usually via a web browser.. Businesses using SaaS have no need to purchase, install, update or maintain software, as this is handled by the service providers. In addition, the service dynamically scales to the usage needs of the company and cloud-based applications are frequently faster to implement and more flexible to adapt and update.
• PaaS provides a cloud-based environment with everything required to support the complete lifecycle of building and delivering web-based (cloud) applications without the cost and complexity of buying and managing the underlying hardware, software, provisioning and hosting. This allows businesses to develop applications and make them available faster, deploy new web applications to the cloud in minutes and reduce complexity with middleware as a service. The growing trend toward modular software with published APIs will enhance the speed and flexibility that cloud already offers.
• IaaS provides organizations with computing resources including servers, networking, storage and data center space on a pay-per-use basis, often to run existing workloads.
