    What Is Cloud Computing? Skills Required and Career Outlook

    Cloud computing offers on-demand delivery of off-site computing resources through the internet. Most often utilized for convenient file storage, cloud computing’s origins go back as far as a 1960s computer network theory from a U.S. Department of Defense scientist. About 30 years later, AT&T introduced Personal Link Services, its web-based storage service. In 2006, when Amazon launched Amazon Web Services (AWS), the term “the cloud” became part of the vernacular.

    Cloud computing is decades old. But it is ever-evolving and remains a catalyst for innovation and the foundation for many emerging technologies. Cloud computing underpins advancements in artificial intelligence, machine learning, and data analytics. Individuals interested in exploring what cloud computing is can take advantage of a bootcamp education program to learn how to use, implement, and innovate cloud computing concepts and help shape the future of technology.

    What Is Cloud Computing?

    Cloud computing works through a distributed network of servers that handle data storage and processing for users to access via the internet. For example, when someone saves a document from their device using cloud computing, the document is stored on a remote server. The server could reside in a data center thousands of miles away. But, when the user is ready to continue working on the document, they can access it anytime, right from their device (or multiple devices). Also, any other person authorized by the user can access the document from anywhere.

    Cloud computing eliminates the need for an organization to own certain physical computing infrastructure, which can be expensive and difficult to maintain. In the cloud computing model, the responsibility for managing the servers and their associated hardware belongs to a service provider, such as Microsoft Azure.

    Besides servers, other critical components of cloud computing include:

    • Storage: Technology such as computer components and recording media used for preserving digital data

    • Applications: Software that enables computers to execute specific tasks

    • Services: Technology that enables users to access and manage cloud applications via the Internet and on-demand

    Cloud Computing Categories

    Organizations are turning to cloud computing to prepare for the future. According to Google, over 41% of business leaders report increased cloud adoption. The growing popularity of cloud computing has led cloud computing providers to develop different models to meet different user needs. These include infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS) models:

    Infrastructure as a Service

    In the infrastructure as a service (IaaS) model, a cloud services provider provides computing resources virtually. This format eliminates the need for users to maintain their own data center resources on-site. Managing and maintaining this infrastructure is the responsibility of the cloud services provider—allowing organizations to focus on business operations. Examples of IaaS include Microsoft Azure and AWS.

    Platform as a Service

    The platform as a service (PaaS) model offers users an on-demand platform where they can develop, test, and deploy applications. In this model, the service provider still manages the underlying infrastructure, which allows developers to optimize their app development process. It can also help improve collaboration among individuals working in different locations. PaaS can ease the integration of applications and permit faster application development. Examples of PaaS include Salesforce and Dropbox.

    Software as a Service

    Cloud computing users can access various software as a service (SaaS) cloud-based applications. The types of applications available vary—from office software to specialized services like machine learning and content delivery. These applications run on cloud infrastructure instead of users’ physical devices or servers. Examples of SaaS include Google Workspace and Slack.

    5 Benefits of Cloud Computing

    When researching what cloud computing is, individuals may be most interested in its benefits. Cloud computing is ideal for storing, processing, and accessing large volumes of data. It also can facilitate collaboration and real-time data analysis. This allows businesses and individuals to rapidly innovate, develop, and deploy applications. Cloud computing can help organizations achieve formerly unprecedented efficiency, connectivity, and technological advancement.

    Below are some of the most cited benefits of cloud computing by leaders adopting it for their organizations.

    Scalability

    Cloud scalability can enable an organization to stay agile as the business and market evolve. It means a company does not have to buy or manage physical hardware to expand. Rather, a cloud service provider adjusts the computing resources it provides to the company as needed. This can help the company optimize performance and efficiency while saving costs.

    Flexibility

    Cloud computing provides employees with the flexibility to access files through various web-enabled devices, which can foster productivity and promote efficient operations.
