In this post, we will see What What is Cloud Computing Technology | Getting Started with Cloud Computing. It is the delivery of computing services like servers, storage, databases, networking, software, analytics, intelligence and moreover an Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale. You need to pay only for cloud services that you use which helps us to lower our operating costs, run the infrastructure more efficiently and scale as your business needs change.
Cloud technology is the on-demand delivery of computing power, database storage, enterprise or small applications, and other IT resources through the cloud services platform via the internet with pay-as-you-go pricing.
Cloud Computing Basics
It does not matter you are running applications that share photos to millions of mobile users or you’re supporting any critical operations of your business, the cloud services platform provides rapid access to flexible and low cost IT resources.
With cloud computing technology, you don’t need to make significant upfront investments on the hardware and you can spend a lot of time on the heavy lifting of managing the hardware.
Cloud Computing Abilities
- It can leverage remote systems.
- It can scale up or scale down the resources as we need.
- It can provide on-demand self-service.
- It provides universal network access.
- It provides resource pooling.
Delivery models of Cloud Computing
It has mainly three models.
Saas
It is Software as a Service. Software as a service is the software licensing and delivery model in which software is permitted on the subscription basis and is centrally hosted. It is also sometimes referred to as an “on-demand software.” Salesforce provides the Saas.
Paas
It is a Platform as a Service. Platform as a Service (PaaS) or Application Platform as a Service (PaaS) or platform-based service is the category of cloud computing in which the services that provides a platform allowing customers to build, run, and manage the applications without the complexity of building and maintaining the infrastructure which is associated with the developing and launching an app. Most popular example is Google App Engine that provides Paas.
Iaas
It is an Infrastructure as a Service. Infrastructure as a service is online services that provide high-level APIs used to dereference various low-level details of underlying network infrastructure like physical computing resources, location, data partitioning, scaling, security, backup, etc. Amazon Web Services (AWS) provides Iaas.
Cloud Deployment Models
There are mainly three types of clouds.
Private Cloud
Private cloud services are delivered from the business’s data center to internal users. Private cloud model offers the versatility and convenience of the cloud while maintaining the management, control, and security to the local data centers.
Internal users may or may not be billed for the services through IT chargeback. Standard private cloud technologies and vendors include VMware and OpenStack, and AWS. Recenet example is AWS providing the services to the CIA.
Public Cloud
In the public cloud model, the third-party cloud service provider delivers the cloud services over the internet. Public cloud services are sold on demand, charged by the minute or hour, or long-term commitments are available for many services. Customers only need to pay for the CPU usage, storage or bandwidth they consume.
Leading public cloud providers include Amazon Web Services (AWS), Microsoft Azure, IBM, and Google Cloud Platform.
Hybrid Cloud
A hybrid cloud is the combination of public cloud services and an on-premises private cloud, with orchestration and automation between the two.
Companies can run mission-critical workloads or sensitive applications on a private cloud and use a public cloud to handle the workload bursts or spikes in the demand.
Main goal of the hybrid cloud is to create the unified, automated, scalable environment that takes the advantage of all that the public cloud infrastructure can provide, while still maintaining control over mission-critical data.
How Does Cloud Computing Work?
Cloud computing provides the simple way to access servers, storage, databases and the broad set of application services over the Internet.
The Cloud services platform such as the Amazon Web Services owns and maintains the network hardware required for these application services, while you can provision the servers and use what you need via the web application.
Cloud computing, in turn, refers to the sharing resources, software, and information via a network, in this case, the Internet. The data is stored on the physical servers maintained and controlled by the cloud computing provider, such as Apple which provides the iCloud service. As a user, you access your stored information on a cloud via the Internet.
By using the cloud storage, you don’t need to store the information on your hard drive. Instead, you can access it from any location, any devices, and download on any device, including the laptops, tablets, or smartphones.
Moreover, you can also change the files, such as the Word documents or PowerPoint presentations(PPT).
There are different types of cloud computing services that are available to suit your different requirements. The individual users who want to store the photos, documents, and videos can using the services while others are destined for companies that need great platforms to develop Information Technology applications, for example Facebook which uses cloud services for storing the user data.
Depending on your requirements, the prices will vary. As the individual user, you can get the initial amount of storage for free, such as 5GB with iCloud. If you need the additional storage, you will have to pay the fee. Fees are usually set to monthly or yearly rates, based on the services you are using.
Cloud Computing Planning
Moving an IT application to the cloud is the most critical task.
In the cloud infrastructure world, you need to understand the following points.
- Scale-out
- Distributed
- Loosely coupled
- Automation
- Self-healing
- Active
- Metered Cost
- Latency Tolerant
- Cloud Paas
- Elastic Capacity
- App Supported availability
- Location transparency
We need to think and plan strategically. You need to iterate through feedback loops rapidly.
Continuously improving and automation measuring. Scaling at an accelerating pace.
Application Migration means you need to move the application code and data to the cloud.
For example, if you have a web application already hosted on GoDaddy and now you need to move that application’s code and data to the AWS cloud.
Cloud Security Planning
If you are unable to secure the cloud then some point of time, it will fail for sure.
If you want to secure your cloud then first you need to understand the security options.
You need to be proactive at the self-defense again any threats.
You need to achieve standardization to achieve business benefits while encouraging adaptability, flexibility, and innovation.
Provide clarity in security policies, standards, processes, roles, and accountabilities.
We need to measure and communicate the results.
Drive the continual improvement and build existing capabilities.
Conclusively, What is Cloud Computing Technology | Getting Started with Cloud Computing article is over.
