Introduction Virtualization is the creation of virtual servers, infrastructures, devices and computing resources. Virtualization changes the hardware-software relations and is one of the foundational elements of cloud computing technology that helps utilize the capabilities of cloud computing to the full. Virtualization techniques allow companies to turn virtual their networks, storage, servers, data, desktops and applications.…
Introduction Resource pooling is an IT term used in cloud computing environments to describe a situation in which providers serve multiple clients, customers or “tenants” with provisional and scalable services. These services can be adjusted to suit each client’s needs without any changes being apparent to the client or end user. Cloud computing platforms are…
Introduction A Cloud Hypervisor is software that enables the sharing of cloud provider’s physical compute and memory resources across multiple virtual machines (VMs). Originally created for mainframe computers in the 1960s, hypervisors gained wide popularity with the introduction of VMware for industry standard servers in the 1990s, enabling a single physical server to independently run…
Introduction Infrastructure as a service (IaaS) is a form of cloud computing that provides virtualized computing resources over the internet. IaaS is one of the three main categories of cloud computing services, alongside software as a service (SaaS) and platform as a service (PaaS). In the IaaS model, the cloud provider manages IT infrastructures such…
Introduction PaaS is a cloud computing service that uses virtualization to offer an application-development platform to developers or organizations. This platform includes computing, memory, storage, database and other app development services. PaaS solutions can be used to develop software for internal use or offered for sale. PaaS technology offers a company virtual infrastructure, such as…
Introduction A data center — also known as a datacenter or data centre — is a facility composed of networked computers, storage systems and computing infrastructure that businesses and other organizations use to organize, process, store and disseminate large amounts of data. A business typically relies heavily upon the applications, services and data contained within…
Introduction A cloud SLA (cloud service-level agreement) is an agreement between a cloud service provider and a customer that ensures a minimum level of service is maintained. It guarantees levels of reliability, availability and responsiveness to systems and applications; specifies who governs when there is a service interruption; and describes penalties if service levels are…
Cloud cost optimization is finding ways to run applications in the cloud, performing work or providing value to the business, at the lowest possible cost, and using cloud providers as cost-efficiently as possible. Optimization as a practice ranges from simple business management to complex scientific and engineering areas like operations research, decision science and analytics,…
Cloud disaster recovery (CDR) is a cloud-based managed service that helps you quickly recover your organization’s critical systems after a disaster and provides you remote access to your systems in a secure virtual environment. Cloud recovery helps businesses bounce back from natural disasters, cyber-attacks, ransomware, and other threats that can render all files useless in…
A multi cloud security allows organizations to deploy workloads across multiple cloud platforms, including both public clouds, such as AWS, Azure, and Google Cloud Platform, and private clouds. This provides much more flexibility than working with only one cloud platform, allows organizations to better manage costs and avoid vendor lock in, and improves resiliency. However,…
