Testing on a cloud
Today, more than ever, companies are drawn to cloud computing because it provides a cost-effective way to speed service delivery, increase efficiencies and expand (or contract) infrastructure to meet your company’s needs. Quality assurance testing on a cloud allows companies to quickly scale up or down, deploy the services needed and achieve cost savings with pay-as-you-go services. Because the cloud allows companies to leverage economies of scale, many companies use the cloud to achieve significant ROI. While it offers many distinct advantages, if you’re considering moving to a cloud, it’s important to carefully strategize about delivery models, workloads and infrastructure. We can help you analyze your needs and determine the right option.
Software as a Service (SaaS): Provides access to applications hosted on a service provider’s cloud infrastructure. SaaS works for all kinds of businesses, especially small- and medium-sized businesses that are limited by staff and budget constraints, or need access through a web browser or other thin client interface. While SaaS can be delivered over a cloud infrastructure, it’s important to note SaaS is not a cloud in and of itself.
Platform as a Service (PaaS): Allows companies to deploy acquired or custom software applications without incurring the associated upfront, ongoing maintenance and management costs of the underlying infrastructure. In many cases, PaaS can support your entire software development lifecycle.
Infrastructure as a Service (IaaS): Enables you to obtain the infrastructure you need, including servers, security, storage and networks, from a cloud service provider. It works much like a traditional dedicated hosting service; the only difference is, however, with IaaS you use shared, highly scalable resources and only pay for what you use, with no pre-ordering or scheduling necessary.
