What Is Cloud Computing?

Cloud computing is the on-demand delivery of compute power, database, storage, applications , and other IT resources through a cloud services platform via the Internet with pay-as-you-go pricing .

Six Advantages of Cloud Computing

1. Trade capital expense for variable expense
2. Benefifit from massive economies of scale
3. Stop guessing capacity
4. Increase speed and agility
5. Stop spending money running and maintaining data centers
6. Go global in minutes

Types of Cloud Computing

Cloud Computing Models

1.Infrastructure as a Service (IaaS)

Infrastructure as a Service (IaaS) contains the basic building blocks for cloud IT and typically provides access to networking features, computers (virtual or on dedicated hardware), and data storage space. IaaS provides you with the highest level of flflexibility and management control over your IT resources and is most similar to existing IT resources that many IT departments and developers are familiar with today.

2.Platform as a Service (PaaS)

Platform as a Service (PaaS) removes the need for your organization to manage the underlying infrastructure (usually hardware and operating systems) and allows you to focus on the deployment and management of your applications. 

3.Software as a Service (SaaS)

Software as a Service (SaaS) provides you with a completed product that is run and managed by the service provider.With a SaaS offffering you do not have to think about how the service is maintained or how the underlying infrastructure is managed; you only need to think about how you will use that particular piece of software.

Cloud Computing Deployment Models

1.Cloud

A cloud-based application is fully deployed in the cloud and all parts of the application run in the cloud.

2.Hybrid

A hybrid deployment is a way to connect infrastructure and applications between cloud-based resources and existing resources that are not located in the cloud.

3.On-premises

The deployment of resources on-premises, using virtualization and resource management tools, is sometimes called the “private cloud.”

Global Infrastructure

The AWS Cloud infrastructure is built around AWS Regions and Availability Zones.The AWS Cloud operates in 80 Availability Zones within 25 geographic Regions around the world, with announced plans for more Availability Zones and Regions. AWS provides you with the flexibility to place instances and store data within multiple geographic regions as well as across multiple Availability Zones within each AWS Region.
 

AWS Region

• An AWS Region is a physical location in the world where we have multiple Availability Zones
• Each Amazon Region is designed to be completely isolated from the other Amazon Regions
• Achieves the greatest possible fault tolerance and stability

 

Availability Zones

• Availability Zones consist of one or more discrete data centers, each with redundant power, networking, and connectivity, housed in separate facilities.
• Each Availability Zone is isolated and designed as an independent failure zone. This means that Availability Zones are physically separated within a typical metropolitan region and are located in lower risk flood plains
• Availability Zones in a Region are connected through low-latency links

Security and Compliance

Security

The AWS Cloud enables a shared responsibility model . While AWS manages security of the cloud , you are responsible for security in the cloud . This means that you retain control of the security you choose to implement to protect your own content, platform, applications, systems, and networks no difffferently than you would in an on-site data center.

Benefits of AWS Security

• Keep Your Data Safe
• Meet Compliance Requirements
• Save Money
• Scale Quickly

Compliance

The IT infrastructure that AWS provides to its customers is designed and managed in alignment with best security practices and a variety of IT security standards. The following is a partial list of assurance programs with which AWS complies:

• SOC 1/ISAE 3402, SOC 2, SOC 3
