Chapter 3.7 Flashcards
PaaS
Platform as a Service (PaaS) provides preconfigured environments for developing and managing environments. The service provides on-demand computing.
SaaS
Software as a Service (SaaS) is managed by a vendor. It is available over a network and is a pay-as-you-go model. It is a full service product.
IaaS
Infrastructure as a Service (IaaS) allows for outsourcing of equipment and support operations. The service provider owns, maintains and manages the equipment. An IaaS provides access to the system, but the customer must configure it to meet their needs. It is a self-managed solution to cloud concepts.
SECaaS
Security as a Service (SECaaS) is a part of the Software as a Service (SaaS) platform. SECaaS handles and manages security practices for a customer. Any security services provided in the cloud are a subset of SaaS cloud-based technologies.
hybrid
The hybrid cloud is an environment that uses a mix of public, community and private cloud concepts with a single management platform.
Container
Containers use the kernel as a host, but do not host an operating system. A container isolates and protects applications from other parts of the system.
Type I
Type I Hypervisors run directly on system hardware. They do not require operating system involvement. It is often referred to as “bare metal.”
Type II
Type II Hypervisors run as host and require an operating system.
VM Sprawl
VM Sprawl is the effect of mismanaged Virtual Machines. If there are too many virtual machines running on a host, or the VMs are poorly updated, a VM Sprawl will occur.
private
A private cloud is defined as computing services offered either over the Internet or within a private internal network. Only certain authorized users can access a private cloud infrastructure.
public
The Public Cloud exists on the premises of the cloud provider. A service provider makes resources available to the general public over the internet
community
A community cloud is a collaborative effort in which infrastructure is shared between several organizations that share a common interest.
persistent VDE
Persistent VDEs allow users a custom image. Data can be saved locally and accessed at a later date.
non-persistent VDE
Non-persistent Virtual Desktop Environments (VDE) utilizes a central desktop through a remote server. When a user accesses logs on to the desktop, changes and work completed are not saved locally long term. As soon as the user logs off, the desktop reverts back to the image on the central location.
