Are you looking for an overview of cloud computing? Have you been wanting to know what exactly it is and the different types? This article provides all the basics about cloud computing; from what it is to the various types, architectures, and popular cloud-based applications.
What Is Cloud Computing?
Cloud computing is a digital technology that makes use of virtualized resources hosted remotely on-demand across the internet. It allows users to access information and software products without any prior download or installation process.
Types Of Clouds
Clouds come in three main varieties: public, private, and hybrid. Public clouds are owned and managed by third-party cloud providers who deliver their services over the internet. Private clouds are based on virtualized infrastructure and managed by internal IT departments that are responsible for providing applications and resources accessed exclusively by defined users or customer bases. Hybrid clouds combine aspects of public and private clouds with distinct characteristics of each type available such as scalability from public clouds, performance from private clouds, as well as security compliance capabilities between both environments.
Cloud Computing Architectures
Cloud Computing brings an extra layer when it comes to computing architecture that makes it more modern compared to traditional architectures like client-server architecture which can host not just one but multiple applications running in the same instance at different times with completely isolated machines for single application purposes. There are three main components of a cloud computing architecture: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software as a Service (SaaS).
Popular Cloud Applications
With advances in cloud technologies, there has been an increase in innovative uses for them such as web services or streaming media services like Netflix, YouTube, and Apple Music among others that deliver content on demand without requiring any physical hardware being installed at user locations which have made these services extremely popular due both their convenience and cost-effectiveness. Other popular applications include video conferencing technology like Zoom used by millions during the current pandemic along with collaboration solutions like Google Docs which let teams view documents simultaneously while allowing them to add real-time comments using text boxes that aid decision-making processes quickly among many more other creative uses of such technology that have enabled organizations big or small scale operations more efficiently than ever before thereby increasing their productivity significantly over traditional solutions.
Types Of Cloud Computing Services
There are several different types of cloud services available for businesses depending on their needs. Infrastructure as a Service (IaaS) provides companies with basic storage and compute power while Software as a Service (SaaS) includes web-based services such as customer relationship management (CRM). Platform as a Service (PaaS) offers companies an environment in which they can build and deploy applications quickly, while Storage as a Service allows for secure file storage without the need for additional hardware.
Advantages of Cloud Computing
Cloud computing has numerous benefits for organizations due to its scalability, low cost, and automation features. Companies can save money by only paying for what they actually use, allowing them the flexibility to expand and contract at will when demand increases or decreases accordingly. There is also no need to invest in expensive infrastructure upgrades because these can be handled remotely by service providers if needed. Furthermore, there is no need for companies to manage software versions since updates will be handled automatically.
Disadvantages of Cloud Computing
The biggest disadvantage associated with cloud computing is security concerns over who has access to company data stored in the cloud and how it is being managed and protected from unauthorized access or malicious actors seeking entry into systems containing sensitive information. Additionally, organizations have limited control over Infrastructure as a Service solution because they are provided by third-party service providers, sometimes making it difficult for organizations operating in extremely regulated industries like healthcare where unexpected modifications could introduce compliance issues that make managing IT solutions more difficult.
