basics of cloud computing
Basics of Cloud Computing
  • Whether you are running applications that share photos to millions of mobile users or you’re supporting the critical operations of your business, a cloud services platform provides rapid access to flexible and low cost IT resources.
  • With cloud computing, you don’t need to make large upfront investments in hardware and spend a lot of time on the heavy lifting of managing that hardware.
  • Amazon Web Services (AWS) is a secure cloud services platform, offering compute power, database storage, content delivery and other functionality to help businesses scale and grow. 
  • If you too want to make yourself as an Amazon Cloud specialist!, it would be advisable that you take AWS Training in Chennai.
how does cloud computing work
How Does Cloud Computing Work?
  • Cloud computing provides a simple way to access servers, storage, databases and a broad set of application services over the Internet.
  • A Cloud services platform such as Amazon Web Services owns and maintains the network-connected hardware required for these application services, while you provision and use what you need via a web application.
types of cloud computing
Types of Cloud Computing
  • Cloud computing is usually described in one of two ways. Either based on the cloud location, or on the service that the cloud is offering.

Based on a cloud location

  • public,
  • private,
  • hybrid
  • community cloud

Based on a service

  • Infrastructure as a Service (IaaS)
  • Platform as a Service (PaaS)
  • Software as a Service (SaaS)
public cloud mean that the whole computing

public cloud mean that the whole computing infrastructure is located on the premises of a cloud computing company that offers the cloud service. The location remains, thus, separate from the customer and he has no physical control over the infrastructure.

Advantages

  • Virtually unlimited resources – You can instantly provision virtually unlimited amount of resources
  • Scalability & Elasticity – You can scale up or down your resources to meet demand peaks and lows, and you pay only for what you use
  • Pay as you go – No Capex, you pay a monthly bill

Limitations

  • Lack of Perceived Amortization Benefits on Investment
  • Compliance – Public Cloud providers may not be following all the regulatory compliance required by an organization.
private cloud means using a cloud infrastructure

Private cloud means using a cloud infrastructure (network) solely by one customer/organization. It is not shared with others, yet it is remotely located. The companies have an option of choosing an on-premise private cloud as well, which is more expensive, but they do have a physical control over the infrastructure.

Advantages

  • Security – There is a sense of security among organizations as the data resides on premise
  • Compliance – Enterprises can comply to the compliance standards required for their industries and follow the required corporate governance structure for their organizations

Limitations

  • Costs – Organizations need to own the hardware, storage and networking resources upfront and also spend on the maintenance of all the resources
  • Complexity – Private Clouds are complex to deploy and maintain because of the complex virtualization of the hardware resources
hybrid cloud means using both private and public

Hybrid cloud means, using both private and public clouds, depending on their purpose

  • Hybrid cloud can also mean the ability to connect collocation, managed and or dedicated services with cloud resources.

Advantages

  • FlexibilityOrganizations can make use of various Public and Private Clouds to utilize the advantages of both the deployment models.
  • Cloud Bursting – You can run an application on private cloud and burst it to public cloud to meet demand peaks

Limitations

  • Complexity – To deploy a hybrid model is quite complex because of the varying standards of each provider
infrastructure as a service iaas infrastructure

Infrastructure as a Service (IaaS):

  • Infrastructure as a Service, sometimes abbreviated as IaaS, contains the basic building blocks for cloud IT and typically provide access to networking features, computers (virtual or on dedicated hardware), and data storage space.
  • Infrastructure as a Service provides you with the highest level of flexibility 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.

Platform as a Service (PaaS):

  • Platforms as a service remove the need for organizations to manage the underlying infrastructure (usually hardware and operating systems) and allow you to focus on the deployment and management of your applications.
this helps you be more efficient

This helps you be more efficient as you don’t need to worry about resource procurement, capacity planning, software maintenance, patching, or any of the other undifferentiated heavy lifting involved in running your application.

Software as a Service (SaaS):

  • Software as a Service provides you with a completed product that is run and managed by the service provider. In most cases, people referring to Software as a Service are referring to end-user applications.
  • A common example of a SaaS application is web-based email where you can send and receive email without having to manage feature additions to the email product or maintaining the servers and operating systems that the email program is running on.
