Cloud computing majorly involves delivery of hosted services on the internet. The term cloud computing was derived, or rather was inspired, from the cloud symbol used in flowcharts to represent the internet. The major goal of cloud computing services is to offer easy, efficient, and speed access to computing systems and IT services.
Cloud computing services can be classified into three categories:
• Software as a service (SaaS)
• Infrastructure as a service (IaaS)
• Platform as a service (PaaS)
This categorization is done based on the delivery service model. Let’s talk more about SaaS, IaaS and PaaS.
Software as a service, abbreviated as SaaS, is a software distribution model. It offers software applications on the internet called web services. Using the SaaS model, professionals can access the web applications and services from any location.
Infrastructure as a service, abbreviated as IaaS, is a cloud computing online service that offers storage options, servers and networking services to vendors. It is used to get details of network infrastructure providers like AWS. These services tend to workload needs of organizations by offering storage facilities in various options.
Platform as a service, abbreviated as PaaS, is a cloud computing model that offers host development tools to users and organizations for cloud infrastructures. Users get access to these development tools over the internet. Features like APIs, online portals or gateway software are involved.
Cloud computing came into existence somewhere between the 1950s and 1960s.
Large companies started using computers in the 1950s. It was a revolution for the growing industries. However, unlike the companies in 2000s, those in 1950s didn’t provide computers for every employee. There was a cost restraint involved. It was during the late 1950s and the early 1960s that time-sharing was discovered. The idea was to use the processor time efficiently.
This resulted in better use of processing power and also reduced downtime. It also allowed users to use several features of computing mainframes at once. This whole instance led to the birth of shared computing resources which in turn served as the base for modern cloud computing.
The basic feature that separates a public cloud and a private cloud is that public cloud services are open to anyone on the internet for buying but private cloud services aren’t. A private cloud is more of a proprietary network that offers hosted services to only a small number of people. It is secured with features like passwords and permission settings.
Cloud computing allows users/clients to access data using the internet. They can get information from databases using remote servers. Here the internet network connection plays a vital role. It bridges the two ends of the process – front end and the back end. It facilitates efficient of data exchange. The data stored in back end is accessed by the front end. The entire process of access and flow of information between the front end and the back end is handled by central server.
Google Docs, Microsoft Office 365
Google Emails
Skype
Google calendar
Zoom calling
All of these are cloud based service models. These serve as good examples of modern storage solutions as opposed to traditional web hosting. Let’s find out in what ways cloud computing is different from traditional web hosting.
Unlike traditional web hosting, cloud computing gives users and option to use as much of a service as they want. The service is offered based on the demand instead of a standard model. Cloud computing model follows the pricing model that is based on time.
Cloud computing offers numerous benefits for organizations and users using the service. Some of them are:
Reduced costs: The usage of cloud infrastructure has proven to be a cost-effective option for several organizations. With cloud computing, businesses can cut down expenses in areas like hardware, equipment, utilities, and more.
Less manpower: With use of cloud services, companies need not build and manage data centers that need personal supervision.
Reduces downtime: As discussed earlier, Cloud computing cuts down on downtime. It helps in better use of programming time.
Flexibility: Information stored in cloud can be easily accessed by users from any part of the world. They can get access to the stored data using any device connected to the internet. This eliminates the use of other storage devices.
Increased productivity: Cloud computing enables employees to work better and faster. It allows them fast access to resources. Employees can retrieve or store data efficiently and on the go.
Better data safety: Cloud computing has significantly reduced risks of data loss. Organizations no longer have to worry about data loss caused by device related issues. The data stored in cloud can be accessed from any device and from anywhere. This helps in better disaster management and faster data recovery.
In the recent years, with rise in demand for cloud services, several players have joined the market. Most popular vendors whose services are trusted and used worldwide are,
Amazon Web Services (AWS)
Google Cloud Platform
Microsoft Azure
IBM
Apple
Oracle Cloud
VMware
SAP
Several organizations are migrating to public clouds. The rise in digital transformation is pushing companies to keep up. With the vast amount of data being generated, used, and transformed, better storage options are in demand. This resulted in the rapid adaptation of cloud computing by organizations all over the world. The use of the public cloud has become prominent for the same reason.
Popular cloud computing service providers like Amazon, IBM, VMware, and others are working relentlessly to meet the growing demand. This has led to a rise in demand for cloud professionals like cloud architects, cloud engineers, and others.
Cloud Computing has become an essential skill in the IT industry. With organizations moving to cloud infrastructure, professionals with cloud computing skills are getting hired and promoted easily. This makes it clear that gaining cloud computing skills pays off.
