Cloud Computing For Beginners?

Cloud computing is the provision of computing services (including servers, storage, databases, networking, software, analytics, and intelligence) – providing rapid innovation, elastic resources, and economies of scale over the Internet (the cloud). With cloud services, you typically only pay for what you use, helping to reduce operating costs, make your infrastructure run more efficiently, and be able to adjust your business.

The biggest advantage of cloud computing

Cloud computing is a major shift for enterprises to abandon the traditional thinking of IT resources. Here are 7 common reasons organizations turn to cloud computing services:

Cost

Cloud computing frees you from the capital investment required to buy hardware and software and to set up and run an on-site data center, including server racks, 24/7 power for efficiency and cooling, and IT specialists to manage the infrastructure. It also increases speed.

Speed

Cloud computing services are provided as on-demand self-service, so massive computing resources can often be provisioned in minutes with just a few mouse clicks, giving businesses great flexibility and taking the stress out of capacity planning.

Global zoom

The advantages of cloud computing services include elastic scalability. For the cloud, this means being able to provide the right amount of IT resources, such as more or less computing power, storage space, bandwidth, from the right geographic location when needed.

work efficiency

On-site data centers often require a lot of “racks and stacks” – hardware setup, software patches, and other time-consuming IT management chores. Cloud computing avoids most of these tasks, freeing IT teams to spend their time achieving more important business goals.

Performance

Largest cloud services run on a global network of secure data centers that are regularly upgraded to the latest fast and efficient computing hardware. Compared to a single enterprise data center, it provides several benefits, including reduced network latency for applications and improved economics of scaling.

Reliability

Cloud computing simplifies data backup, disaster recovery, and business continuity at a lower cost because data can be mirrored at multiple redundant sites in the cloud provider’s network

Safety

Many cloud providers offer a wide range of policies, techniques, and controls for improving the overall security posture, which help protect data, applications, and infrastructure from potential threats.

Types of cloud computing

Not all clouds are the same, and no one cloud is right for everyone. To help provide the right solution to meet customer needs, a number of different models, types and services have been developed.

First, you need to determine the type of cloud development, or cloud computing infrastructure, based on which cloud services will be implemented. There are three different approaches to deploying cloud computing resources: public cloud, private cloud, and hybrid cloud.

Public Cloud

Public clouds are owned and operated by third-party cloud service providers who provide their computing resources (such as servers and storage space) over the Internet. In the public cloud, all hardware, software, and other supporting infrastructure are owned and managed by the cloud provider. Use the web browser to access these services and manage your account. .

Private Cloud

A private cloud refers to cloud computing resources dedicated to the use of a business or organization. A private cloud can actually sit on top of a company’s on-site data center. there are Some companies also pay third-party service providers to host their private clouds. In the private cloud, services and infrastructure are maintained on a private network.

Hybrid Cloud

Hybrid clouds combine public and private clouds, tying them together through technologies that allow data and applications to be shared between them. Hybrid clouds allow data and applications to move between private and public clouds, giving you more flexibility in your business and more deployment options, helping you optimize your existing infrastructure, security, and compliance.

Types of cloud services: SaaS, IaaS, PaaS, and serverless

Four broad categories of Most cloud computing services : Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Serverless, and Software as a Service (SaaS). They are sometimes called cloud computing “stacks” because they build upon each other. Understanding these services and the differences between them can make it easier for you to achieve your business goals.

Software as a Service (SaaS)

Software as a Service (SaaS) is a method of delivering software applications over the Internet, usually on-demand on a subscription basis. With SaaS, the cloud provider hosts and manages the software applications and infrastructure, and is responsible for maintenance such as software upgrades and security patches. Users (usually using a phone, tablet, or web browser on a PC) connect to the application over the Internet.

Common SaaS Scenarios

If you use a web-based email service (such as Outlook, Hotmail, or Yahoo! Mail), you’re already using a form of SaaS. Using these services, you can log in to your account over the Internet (usually from a web browser). Email software resides on the service provider’s network, and your mail is stored there. You can access your email and saved messages from a web browser on any Internet-connected computer or mobile device.

For organizational use, productivity applications such as email, collaboration, and calendaring, as well as advanced business applications such as customer relationship management (CRM), enterprise resource planning (ERP), and document management, can be rented. You can pay for use of these apps on a subscription basis or based on usage level.

Advantages of SaaS

Advanced applications are available. You don’t need to buy, install, update, or maintain any hardware, middleware, or software to deliver SaaS applications to users. SaaS enables businesses that lack the resources to purchase, deploy, and manage the necessary infrastructure and software on their own to use highly advanced enterprise applications such as ERP and CRM.

Pay only for what you use. And because the SaaS service will automatically scale up and down based on usage levels, you’ll also save money.

Free client software. Users can run most SaaS applications directly from their web browsers without downloading and installing any software (some applications require plug-ins). This means that you don’t need to buy and install special software for your users.

Easily enhance employee mobility. SaaS allows you to easily enhance employee “mobility” because users can access SaaS applications and data from any Internet-connected computer or mobile device. There’s no need to think about developing your app to run on different types of computers and devices, because the service provider has already done that. In addition, there is no need to learn specialized knowledge to deal with the security concerns of mobile computing. A carefully chosen service provider will keep your data safe, regardless of the type of device that uses your data.

Access app data from anywhere. Once data is stored in the cloud, users can access their information from any Internet-connected computer or mobile device. And by storing app data in the cloud, no data is lost in the event of a user’s computer or mobile device failure.

Infrastructure as a Service (IaaS)

The most basic category of cloud computing services. With IaaS, you rent IT infrastructure, such as servers and virtual machines (VMs), storage, networking, and operating systems, from a service provider on a pay-as-you-go basis.

Platform as a Service (PaaS)

Platform as a Service (PaaS) refers to cloud computing services that provide the environment needed to develop, test, deliver, and manage software applications on demand. PaaS is designed to make it easier for developers to quickly create web or mobile applications without having to worry about setting up or managing the server, storage, network, and database infrastructure necessary for development.

Serverless computing

Overlapped using PaaS, serverless computing focuses on building application functionality without spending time continuing to manage the servers and infrastructure required to manage it. The cloud supplier handles setup, space planning, and managing the server for you. Serverless architectures are highly scalable and event-driven, and resources are only used when certain functions or events occur.

Use cloud computing

Chances are you’re using cloud computing right now, even if you don’t realize it. When you use online services to send emails, edit documents, watch movies or TV, listen to music, play games, or store pictures and other files, it’s likely that cloud computing is behind the scenes that makes it all possible. Although cloud computing services have been around for less than 10 years, organizations ranging from small startups to global corporations, government agencies, non-profits are actively adopting the technology for a variety of reasons.

Here are a few examples of what is possible using cloud services provided by cloud providers:

Create cloud-native applications

Faster build, deploy and scale applications (web, mobile, and API). Leverage cloud-native technologies and methodologies such as containers, Kubernetes, microservices architecture, API-driven communication, and DevOps.

Build and test the application

Reduce application development costs and save time with a cloud infrastructure that can easily scale up or down.

Store, backup and restore data

Transferring data over the Internet to an offline cloud storage system accessible from any location and any device reduces the cost of protecting data (when massively scaled).

analyze data

Unify data across teams, departments, and locations in the cloud. Then use cloud services such as machine learning and artificial intelligence to uncover insights and make smarter decisions.

Stream audio and video

Connect with your audience anytime, anywhere, from any device, with globally distributed high-definition video and audio.

Embedded intelligence

Using intelligent models can help engage customers and uncover valuable insights from captured data.

software on demand

On-demand software, also known as software as a service (SaaS), provides customers with the latest software versions and updates anytime, anywhere.
