In the most basic terms, cloud computing provides on-demand computing services over the Internet for things like storage, processing power, and application hosting. Instead of companies having to build their own data center or IT infrastructure, an extremely costly and highly technical task, companies can work with cloud service providers to access the application they need. Companies will only pay for what they need when they need it, rather than designing a complex computer system that requires constant maintenance and investment.
Cloud computing services
There are many things that can happen in the cloud and commercial applications are not the only ones that take advantage of storage and hosting applications. Think of the average iPhone apps and storage options for media, files, and gaming. Computer services range from complex processing powers with artificial intelligence computing to basic or office data storage applications such as Microsoft Word or Excel. Cloud services can help you with any service that does not require physical or direct contact with a specific part of your computer hardware.
Examples of Cloud Computing
Thanks to improvements in basic 5G network services, many smartphone users rely on cloud computing every day. Email services like Gmail are accessed via smartphones or tablets, as the service has its data hosted in the cloud. Netflix and Disney + are streaming services where videos and media files are stored in the cloud and accessed by millions of people around the world. Software development is moving to cloud-based applications, where it is no longer necessary to install software disks on all computers that need access to a specific program.
Importance of Cloud Computing
The cloud is not new to the computer scene, but it is fast becoming one of the most important areas of IT development and improvement. More than a third of all money spent worldwide on IT services goes to cloud computing infrastructure. There are several major cloud service providers spending money to continue developing access, but the average business is also spending money to move workloads and processes to cloud-based solutions. Companies with enough resources are also working to create private cloud systems for their organization.
Security in cloud computing
As with any area of IT, security concerns abound with cloud computing and services. A cloud environment faces security threats similar to those of a traditional data center. Software systems that run the service have vulnerabilities that can be exploited by an incorrect individual or group. The challenge of these vulnerabilities is to define who is responsible for a successful cyber attack. Cloud service providers and consumers share responsibility for data security, but consumers have the least share in controlling cloud-based security protocols.
Cloud security originates with the service provider, but the consumer should follow best practices for authorized access and use. Local IT departments can provide tracking and logging of all users, accessed applications, and data storage for a specific company, adding another layer of security to the cloud host’s defenses against cyberattack. Because cloud computing is growing so rapidly, security concerns will continue to be prioritized to ensure the secure storage and transmission of data worldwide and to private companies.
Cloud computing models
There are three models that are used in cloud computing. The first is Infrastructure as a service. This is where fundamental aspects of computing as a virtual or physical server, as a storage application, or as a network service are rented. The next layer is Platform-as-a-Service, which includes the basics, but also includes the various programs or tools a developer may need to build an additional feature. These are more complex and include operating systems, database management and middleware. Software-as-a-Service is the instant delivery of an application that is consumed immediately.
The most dominant cloud computing model is Software-as-a-Service, as it is where most of the public spends money. However, it is still early in cloud research and development, and commercial companies will soon compete with the public’s reliance on cloud services.
