Introduction Most Python projects we develop will have dependencies: code written by other people that we install and use, so that we don’t have to re-write it ourselves. For example, the requests library is a popular third-party dependency to make HTTP requests. The flask library is used to create web applications. There are thousands upon…
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…
Introduction Docker is an open source software platform to create, deploy and manage virtualized application containers on a common operating system (OS), with an ecosystem of allied tools. How Docker works Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.
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…
