Cloud computing refers to the use of hosted services, such as data storage, servers, databases, networks and online software, Where data is stored on actual servers, which are maintained by a cloud service provider, Instead of storing files on a storage device or hard drive The user can save it on the cloud, making it possible to access files from anywhere As long as they have access to the web, and to learn about cloud computing's working mechanism and benefits, read on.
How does cloud computing work?
Cloud computing works by allowing client devices to access data online, from servers, databases and computers remotely, where connecting to the Internet via a central server, front end (including access to client's device, browser, network and cloud software applications) back end, which consists of databases, servers and computers) The backend acts as a repository for storing data accessed through the front end.
Benefits of cloud computing
For a variety of reasons, including cost reduction, increased productivity, efficiency, speed, performance and security, cloud computing is an emerging choice between individuals and businesses, and has many benefits, including:
1. Cost savings
Cost saving is one of the biggest advantages of cloud computing, it helps you save big capital cost, because with cloud computing you don't need any physical investments in hardware, nor do you need trained personnel to maintain devices, where equipment is purchased and managed by the cloud service provider.
2. Competitive Advantage
Cloud computing offers a competitive advantage over your competitors, it's one of the best benefits of cloud services that helps you access the latest apps at any time, without spending your time and money on installation processes.
3. High Speed
Cloud computing allows you to quickly deploy your service with fewer clicks, this faster deployment allows you to get the resources required for your system in a few minutes.
4. Backup and Data Recovery
Once the data is stored in the cloud, it is easier to get backup and restore it, which takes a long time in an in-house process.
5. Automated software integration
Automated software integration is one of the most important features of cloud computing, you do not need to make additional efforts to customize and integrate your apps according to your preferences.
Reliability is one of the biggest benefits of cloud computing, where you can always get instant updates on changes.
Employees working in buildings or in remote locations can easily access all of their services through automatic mobility provided by cloud computing.
8. Unlimited storage capacity
Cloud computing offers almost unlimited storage, you can at any time quickly increase your storage capacity with a very symbolic monthly fee.
Cloud computing platform helps employees located in different geographical areas to collaborate in a very convenient and secure way.
10. Rapid deployment
Last but not least, cloud computing gives you the advantage of fast deployment, so, when you decide to use the cloud, your entire system can work in very few minutes, although the amount of time taken depends on the type of technologies used in your business.
Types of cloud computing
There are 4 types of cloud deployment models: public cloud, private cloud, mixed cloud, and community cloud:
1. Public Cloud
The public cloud is a type of hosting in which cloud services are provided via a network for public use, customers in this type of cloud computing have no control over the infrastructure site, the public cloud cost is also shared by all users, and may be free or in the form of a licensing policy such as payment per user.
Public cloud computing is great for organizations that require host app management and different applications used by users.
2. Special Cloud
A private cloud is a cloud infrastructure used by only one enterprise, where organizations give greater control over security and data protected by a firewall and are managed internally, and can also be hosted internally or externally.
Special cloud computing is great for organizations that have high security requirements, high management requirements and runtime requirements.
3. Hybrid Cloud
Hybrid Cloud uses both private and public cloud but can remain separate entities, where resources are managed or can be provided either internally or by external providers.
Hybrid cloud computing is great for scalability, flexibility and security, for example an organization that can use public cloud computing to interact with customers while keeping their data safe through a private cloud.
4. Cloud Community
It is a shared infrastructure among organizations belonging to a particular community, an example of which is community cloud computing in a country's banks, government or business companies, which can be hosted internally or by an external provider.
Community cloud is useful for enterprises working on joint ventures that need centralized cloud computing capacity to manage, build and implement their projects.
Types of cloud services: IaaS, PaaS, Serverless and SaaS
Most cloud computing services are divided into four broad categories: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Server-Free, and Software as a Service (SaaS). These are sometimes called cloud computing "stack" because they build on top of each other. Knowing what they are and how they differ makes it easy to achieve your business goals:
Infrastructure as a Service (IaaS)
A basic category of cloud computing services, using IaaS, you can rent the IT infrastructure - servers, virtual devices (VMs), storage, networks and operating systems - from the cloud provider on a pay-as-you-go basis.
Platform as a Service (PaaS)
The platform refers as a service to cloud computing services that provide a bespoke environment for the development, testing, delivery and management of software applications, PaaS is designed to make it easier for developers to rapidly create web or mobile apps, without worrying about setting up or managing the basic infrastructure for servers, storage, network and databases needed for development.
Interchangeably with PaaS, server-free cloud computing focuses on building app functionality without spending time managing the servers and infrastructure required continuously to do so, The cloud provider will set up, plan capacity and manage the server on your behalf and structures that do not require a server are highly scalable and event-based, Resources are used only when a particular function or operator occurs.
Software as a Service (SaaS)
Software as a service is a way to deliver online software applications, on demand and usually on a subscription basis. Using SaaS, cloud providers host and manage the software application and basic infrastructure, and handle any maintenance, such as software upgrades and security patches, users connect to the online application, usually using a web browser on their phones, tablets or computers.
In addition to the benefits of cloud computing mentioned above, the cloud can help manage the pressures that companies and IT organizations face and meet market demands quickly, making it a driving force for change in today's digital world.
