With the exponential increase in data use that has accompanied society's transition into the digital 21st century, it is becoming more and more difficult for individuals and organisations to keep all of their vital information, programs, and systems up and running on in-house computer servers. SaaS is used to minimize the operational cost to the maximum extent.All this seems to indicate that given the apparent direction in which the industry is moving, there’s never been a better time to get your head in the cloud.Ĭloud computing is a term that has gained widespread use over the last few years. E.g., Microsoft One Drive, Dropbox, WordPress, Office 365, and Amazon Kindle. It delivers software over the internet, on-demand, and typically on a subscription basis. Software as a Service (SaaS): It provides a centrally hosted and managed software services to the end-users.Using PaaS, the flexibility gets reduce, but the management of the environment is taken care of by the cloud vendors. The developer is responsible for the application, and the PaaS vendor provides the ability to deploy and run it. Platform as a Service (PaaS): This service provides an on-demand environment for developing, testing, delivering, and managing software applications.Using IaaS, we get maximum flexibility, but still, we need to put more effort into maintenance. Using IaaS, we don’t need to care about the hardware or virtualization software, but other than that, we do have to manage everything else. We can create VM running Windows or Linux and install anything we want on it.

Infrastructure as a Service (IaaS): In IaaS, we can rent IT infrastructures like servers and virtual machines (VMs), storage, networks, operating systems from a cloud service vendor.Hybrid cloud provides flexibility and more deployment options to the business. Hybrid Cloud: It is the combination of public and private clouds, which is bounded together by technology that allows data applications to be shared between them.

A private cloud may physically be located on the company’s on-site datacentre or hosted by a third-party service provider. Private Cloud: The cloud computing resources that are exclusively used inside a single business or organization are termed as a private cloud.It delivers computing resources such as servers, software, and storage over the internet Public Cloud: The cloud resources that are owned and operated by a third-party cloud service provider are termed as public clouds.Security: Many cloud vendors offer a broad set of policies, technologies, and controls that strengthen our data security.Reliability: Backup and recovery of data are less expensive and very fast for business continuity.So, in this way, the IT team can be more productive and focus on achieving business goals. We do not need to apply patching, as well as no need to maintain hardware and software. Productivity: While using cloud computing, we put less operational effort.Scalability: We can increase or decrease the requirement of resources according to the business requirements.Speed: Resources can be accessed in minutes, typically within a few clicks.Cost: It reduces the huge capital costs of buying hardware and software.Some cloud service providers are in the following figure. The cloud environment provides an easily accessible online portal that makes handy for the user to manage the compute, storage, network, and application resources. The cloud computing services will be charged based on usage. We can take any required services on rent. They also provide a wide variety of software and platform as a service.

After doing all the set-up, we become responsible for maintaining it through its entire lifecycle.īut if we choose Cloud Computing, a cloud vendor is responsible for the hardware purchase and maintenance. With an on-premises datacentre, we have to manage everything, such as purchasing and installing hardware, virtualization, installing the operating system, and any other required applications, setting up the network, configuring the firewall, and setting up storage for data. Next → ← prev Introduction to Cloud ComputingĬloud Computing is the delivery of computing services such as servers, storage, databases, networking, software, analytics, intelligence, and more, over the Cloud (Internet).Ĭloud Computing provides an alternative to the on-premises datacentre.
