Cloud computing has become increasingly popular due to the rise of digital transformation. This type of service involves providing hosted services over the internet. There are three main types of these services which are IaaS or infrastructure as a service, PaaS or platform as a service, and SaaS or software as a service.
A cloud can also be categorized as either private or public. A public cloud offers services to anyone on the internet while a private cloud is a data center or a proprietary network that supplies hosted services to a few people with specific permission and access settings. Regardless of whether the type of cloud service is public or private, the goal of cloud computing remains the same, which is to provide easy and scalable access to computing resources and IT services.
Another term frequently used in the cloud computing industry is cloud infrastructure. This involves the software and hardware components that are required for the execution of the cloud computing model. On the other hand, cloud computing may also be referred to as on-demand computing and utility computing.
How Does Cloud Computing Work?
So, how does cloud computing work? Cloud computing services work by enabling client devices to access data over the internet and from remote databases, computers, or servers.
The service comprises front-end and back-end layers. These layers make up the hardware, website, or computer program which are aligned based on how services are accessed by the user. An internet connection will link the front end layer to the back end layer.
The front end involves accessing client devices, networks, browsers, and cloud software applications. On the other hand, the back consists of databases, computers, and servers. Basically, the back end layer will function as a repository that stores up data that is being accessed by the front end layer of this service.
The communications between these layers are being managed by a central server. This server relies on various protocols and standards that facilitate the exchange of data. It uses both middleware and software to help manage the connectivity between the different cloud servers and client devices. In most cases, a dedicated server will be allocated for each application.
Traditional Web Hosting versus Cloud Computing Services
Cloud computing services have three distinct features that distinguish them from a traditional web hosting service.
This type of service is elastic and expandable. This means that the user can actually have as little or as much of the service they need at any given time.
This service is accessible on demand. This means that the user can access large amounts of cloud computing power on demand. In fact, this type of service is either provided or billed on per minute or per hour basis.
This service is managed by the provider. This means that the user simply needs internet access and a device. The increasing interest in cloud computing services can be associated with the increased innovations in terms of innovations as well as distributed computing.
Benefits of Cloud Computing Services
A lot of people are tapping cloud computing services these days because of the very attractive benefits that this service offers. Here are some of the many benefits of cloud computing services:
- Cost-Efficient. This type of service offers cost-saving benefits. With the use of cloud infrastructure, operational costs can significantly be reduced. Many organizations do not need to spend money on buying as well as maintaining equipment. In addition, organizations do not need to spend extra money in investing in facilities, hardware, and building large data centers as their business grows. They do not even have to hire extra IT heads to handle cloud data centers because a dedicated team of experts is already provided by their cloud computing service provider.
- Accessibility and Mobility. Another great benefit of cloud computing services is mobility and accessibility. The information stored in the cloud can be accessed anywhere using any device with an internet connection. This means that the users do not have to carry any storage devices like a USB just so they can access their data. With simply the use of a smartphone connected to the internet, data is readily accessible.
- Disaster Recovery. Data loss is inevitable and this is something that many organizations fear. When data is stored in the cloud, data loss is prevented especially when your devices become inoperable. Data can easily be recovered with cloud-based services.
Challenges Associated with Cloud Computing Service
While there are benefits to cloud computing services, there are also challenges or risks associated with it.
- Cloud Security. One major challenge with cloud-based services is cloud security. There are always threats with data breaches, hackers, and compromised credentials. Thus, it is important to make sure that your cloud computing service provider can provide you with the most updated and secured services.
- Lack of Resources and Expertise. With the increasing advancement in information technology, it can become a struggle to keep up with the growing demands of experts with the proper knowledge and skill set as well as tools to keep up with the operation.
