In the traditional computing model, infrastructure is thought
of as hardware. Hardware solutions
are physical, which means they require space, staff, physical security, planning, and capital
expenditure.
Cloud computing models
Cloud Service Models
Infrastructure as a Service (IaaS)
Platform as a Service (PaaS)
Software as a Service (SaaS)
Infrastructure as a service (IaaS):
Services in this category are the basic building blocks for
,cloud IT and typically provide you with access to networking features, computers (virtual or on
dedicated hardware), and data storage space. IaaS provides you with the highest level of
flexibility and management control over your IT resources. It is the most similar to existing IT
resources that many IT departments and developers are familiar with today
Cloud computing deployment model
Cloud, hybrid, on premises (private cloud)
On-premises (Private Cloud):
Deploying resources on-premises, using virtualization and resource management tools, is
sometimes called private cloud. While on-premises deployment does not provide many of the
benefits of cloud computing, it is sometimes sought for its ability to provide dedicated
resources. In most cases, this deployment model is the same as legacy IT infrastructure, but it
might also use application management and virtualization technologies to increase resource
utilization.
There are many similarities between AWS and the traditional, on-premises IT space:
•AWS security groups, network access control lists (network ACLs), and AWS Identity and Access
Management (IAM) are similar to firewalls, access control lists (ACLs), and administrators.
,•Elastic Load Balancing and Amazon Virtual Private Cloud (Amazon VPC) are similar to routers,
network pipelines, and switches.
•Amazon Machine Images (AMIs) and Amazon Elastic Compute Cloud (Amazon EC2) instances
are similar to on-premises servers.
•Amazon Elastic Block Store (Amazon EBS), Amazon Elastic File System (Amazon EFS),
Amazon Simple Storage Service (Amazon S3), and Amazon Relational Database Service (Amazon
RDS) are similar to direct attached storage (DAS), storage area networks (SAN), network
attached storage (NAS), and a relational database management service (RDBMS).
With AWS services and features, you can do almost everything that you would want to do with a
traditional data center
Platform as a service (PaaS):
Services in this category reduce the need for you to manage the underlying infrastructure
(usually hardware and operating systems) and enable you to focus on the deployment and
management of your applications
Software as a service (SaaS):
Services in this category provide you with a completed product that the service provider runs
and manages. In most cases, software as a service refers to end-user applications. With a SaaS
offering, you do not have to think about how the service is maintained or how the underlying
infrastructure is managed. You need to think only about how you plan to use that particular
piece of software.
6 Advantages of cloud computing
, - Trade capital expense for variable expense
- Benefit from massive economies of scale
- Stop guessing capacity
- Increase speed and agility
- Stop spending money running and maintaining data centers
- Go global in minutes
Web service
An application provisioned using the internet
Categories of AWS services
There are three ways to create and manage resources on the AWS Cloud:
•AWS Management Console:
The console provides a rich graphical interface to a majority of
the features offered by AWS. (Note: From time to time, new features might not have all of their
capabilities included in the console when the feature initially launches.)
