Exploring IaaS (Infrastructure as a Service): Concepts and Aspects

This presentation provides a comprehensive overview of Infrastructure as a Service (IaaS). It begins with an introduction to IaaS, defining it as a service that offers complete infrastructure allocation on the cloud, enabling elasticity and dynamic scaling. The presentation outlines various IaaS resources, including web hosting, firewalls, application support, data maintenance, power backup, and virtualization. It also delves into the architecture of an IaaS cloud platform and key concepts such as resource pooling, cloud bursting, hypervisors, and multi-tenancy. The presentation further lists several IaaS providers like Amazon AWS, Microsoft Azure, and Google Engine. It discusses the positive aspects of IaaS, such as cost-effectiveness, flexibility, scalability, and high availability, as well as the negative aspects, including potential high costs, limited server control, and reliance on high-speed internet. Finally, it highlights key IaaS values like IT, UI, ROI, SLA, and API. Desklib offers a wealth of similar solved assignments and study resources for students.

IaaS (Infrastructure as a
Service)

INTRODUCTION
• IaaS is the service that offers the complete infrastructure
allocation on cloud and make it available for the purpose of
utilization.
• Various resources are provided as the Service and it also
allows elasticity and scaling dynamically.
• The cost of this service vary according to the need that
means pricing model is set according to usage (Li, Qui, Ming,
and Quan, 2012).
• It has the architecture of multi-tenet that allows multiple
users to use the same hardware.

IAAS Resources
• Web Hosting
• Firewalls
• Application Support
• Data maintenance and storage
• Power backup system and data backup
• Support applications and operating systems
• Recovery from disaster
• Load archiving and balancing
• Helpdesk
• Virtualization
• Elasticity (Somasundaram and Govindarajan, 2011).

Architecture of IaaS Cloud
Platform

Key Concepts of IaaS
Development Application
• Resources pooling
• Cloud bursting
• Hypervisor
• Computing Multi-tenant
• Focus on the development of code.
• Database
• Servers
• Open platform
• Code development without installation (Qaisar, 2012).

Various IaaS Providers
• Amazon AWS
• Digital Ocean
• Microsoft Azure
• Rackspace
• Google Engine
• SmartCloud
• OpenStack
• Cloudstack (Garg, Versteeg and Buyya, 2013).

Positives Aspects of IaaS
Services
• Cost effective and savings.
• Services are flexible and are scalable.
• Provide the fast execution and fast time to market.
• The availability is very high and support BC, DR and many
more.
• Focus on the growth of business (Lee, Yan, and Zhao,
2011).
• Saves the time of IT staff and help the environment.

Negative Aspects of IaaS
Services
•Sometimes expensive.
•Backup is created by the client only.
•The server control is poor.
•Limits the requirements in some case.
•Required connection of internet with high
speed.

IaaS Values
•IT (information Technology)
•UI (User Interface)
•ROI (Return of Investment)
•SLA (Service Level Agreement)
•API (Application Programming Interface)
