3. General Characteristics of Cloud Computing and Its Definition
Cloud computing is a software and hardware available to users via the Internet or a
local network as a service allowing the interface to be a user-friendly for a remote
access to the dedicated resources (computing resources, programs, and data).
Self service on demand
Universal access
Resource pooling
Elasticity
Accounting for consumption
4. Trends in the Development of Modern Infrastructure Solutions
The following infrastructure solutions have heavily contributed to the
emergence of a cloud computing concept
computers productivity growth
invention of multi-core and multi-processor computer systems, the
development of blade systems
development of systems and storage area networks
infrastructural consolidation
5. Trends in the Development of Modern Infrastructure Solutions
The development of the IT industry has led to the introduction of several
models of information systems
6. Trends in the Development of Modern Infrastructure Solutions
Mainframe is an all-purpose, high-performance, fault-tolerant server with significant input-output
resources, large volume of operational and external memory for the use in the mission-critical
systems with intensive packet and operational transaction treatment.
7. Trends in the Development of Modern Infrastructure Solutions
Blade-server or blade is a modular single-board computer system that includes a processor and
memory. The blades are inserted into a special chassis with a backplane providing them a network
connection and power supply.
8. Trends in the Development of Modern Infrastructure Solutions
Storage Area Network or SAN is a high-speed switched data transmission
network of servers, workstations, disk storage and tape libraries.
9. Trends in the Development of Modern Infrastructure Solutions
Consolidation is the process of bundling computing resources or
management structures into a single center
10. Virtualization Technology
The process of virtualization is based on the possibility of one computer to do task
of multiple computers by distributing its resources across multiple environments.
12. Virtualization Technology
The main varieties of virtualization are
server virtualization
(paravirtualization
and full
virtualization)
virtualization at the
level of operating
systems
application
virtualization
presentation
virtualization
13. Fundamentals of cloud computing
Cloud computing includes cloud service and deployment models for cloud systems
14. Fundamentals of cloud computing
Cloud computing offers the following web services
Infrastructure as a service (IaaS);
Platform as a service (Paas);
Software as a service (SaaS);
Hardware as a Service (HaaS);
Workplace as a Service (WaaS);
Data as a Service (DaaS);
Security as a Service (SECaaS).
