A Beginner’s Guide to Cloud Computing

Cloud computing has had a huge impact on the way IT is approached today. The technology has brought about new opportunities, ideas and had a hand in creating a new era of business management. Most industries are taking advantage of this technology, and a lot of businesses themselves are attaching the cloud to their products and services.

The question is: what exactly is the cloud, and how does it work?

An Intro to Cloud Computing

Before the days of cloud computing, many companies opted to use traditional servers to carry out operations and store data. Over time, this became costly and challenging; cloud computing was introduced as a more convenient solution to this problem. As a result, today it is possible to deliver almost the full range of computer services over the internet. This completely negates the need for external hardware and software. Instead, a network of remote servers is hosted on the internet. It allows users to access their online services through any device with an internet connection; their location doesn’t matter.

How Does Cloud Computing Work?

To put it in layman’s terms: the cloud has two main sections, the front and the back end. They are connected by an internet network. The front end represents the user, and the back end represents the cloud. The user is able to access the data stored via an internet connection and cloud software. On the other hand, the back end is responsible for storing data securely. The central server follows a set of protocols to facilitate operations.

In addition to the two main components, which are essentially universal, there are three broad models. Firstly, infrastructure as a service (Iaas) which is the most basic service model available. A user can rent their network connectivity, data center, storage, servers and cloud computing software from a provider. Iaas can be customizable, and so it can be used to build a cost-effective solution.

Next, there is platform as a service or paas, and that service provides an environment to develop, test, deliver and manage all of your software applications at your demand. It is more so designed ad geared towards developers because it makes it easier for them to develop websites or apps without having to worry about setting up or managing any underlying infrastructure resources.

Finally, there is software as a service or saas, which is the largest model in cloud computing, and the demand continues to grow. This particular model uses a web browser to deliver apps to clients which are managed by a third-party vendor. Clients access the interface, and most of the apps don’t need downloading because they can be run directly from the browser itself. As a business, it can be difficult when trying to work out which service system to use, iaas vs paas vs saas, but Virtastant’s Guide can help to outline the differences in more detail. In addition, Virtastant’s area of expertise is cloud technology, and they can provide help in cloud optimization, migration and management.

Virtualization & Cloud Computing

The world of cloud computing is vast; it has to be to hold the various processes and operations that it does. Cloud computing virtualization allows the user to utilize the same server to run all of the necessary operations and applications, making it more efficient and reducing costs.

There are four main types when it comes to cloud computing virtualization. First up is application virtualization, which is designed to help users remotely access applications from a server. The server holds the information and allows it to be accessed from any workstation with an internet connection. Next is network virtualization, which refers to the ability to run multiple virtual networks which have separate controls and data plans. It facilitates the creation and provision of virtual networks. There is also desktop virtualization which enables users to emulate a workstation in place of a server. Users can remotely access their desktops regardless of location or machine. Finally, there is server virtualization. This particular technique masks server resources. It stimulates physical servers. It does this by altering their operating systems, processes and numbers, which in turn means that users don’t have to continuously manage complex server resources.

The Benefits of Cloud Computing

Cloud computing is more than just a trendy app or the latest big thing in data management. It has a huge role to play in many industries and businesses today. By using cloud services, businesses are reaping the benefits. Cloud computing is cheaper. In the past running, managing, and deploying local systems was expensive. Cloud computing requires little to no maintenance or staffing because everything is handled by the service provider. It also offers a higher level of flexibility; it is a lot easier to manage resources, and most businesses only pay for what they use too. The process and operations behind cloud computing are simpler, and they can be changed easily to suit the needs of your business. You can easily scale up your storage and access as the business grows.

Cloud computing is also a safer storage method. Hardware can get damaged easily, which could lead to a total loss of your files and resources; this is not the case with cloud technology. Losing data can be incredibly detrimental for a business; it can lead to a loss in revenue, their reputation can take a tumble, and they can lose the trust of their customers. With cloud computing, a data loss is far less likely, and besides, if it were to happen, there are often backup options where the data will be stored in multiple locations, which means there is always a version of your data that is safe. Finally, cloud computing is also often more secure. The data is protected by firewalls and passwords or pins, which stops unauthorized users from accessing it.

To Conclude

Cloud technology may seem a little complicated at first, but it doesn’t have to be. With the proper research and planning, any business can take advantage of everything that cloud computing has to offer. In technological terms, cloud computing is still in its infancy, which means that there are further advancements on the horizon that could offer further applications for this technology.
