Introduction In many ways, the security threats facing today’s traditional data center environments overlap with those of a cloud computing environment. On both sides, cybercriminals aim to take advantage of vulnerabilities found in software. That said, cloud computing introduces another element in that the responsibility of addressing and mitigating those risks is split between the…
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 Ansible is a popular IT automation engine that automates tasks that are either cumbersome or repetitive or complex like configuration management, cloud provisioning, software deployment, and intra-service orchestration. Ansible is used for the multi-tier deployments and it models all of IT infrastructure into one deployment instead of handling each one separately. There are no…
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…
