Cloud Computing

Cloud Computing, also known as “The Cloud,” refers to accessing servers, software, and databases over the internet. Cloud Computing alleviates the need to manage physical data servers or run software applications on one’s device. Computing services, such as servers, storage, databases, networking, software, analytics, intelligence, and applications, are delivered through the internet via cloud servers in data centers all over the world.

The cloud enables users to access files and applications from almost any device, as the computing and storage take place on servers in a data center instead of locally on the user’s device. Users can log into their social media accounts on a new phone if their old phone breaks, recover files, and access their account as if nothing happened.

For businesses, IT teams are often considered a “cost center.” Migrating workloads to cloud computing can be a cost-saving measure. For example, less overhead is required since there is no longer a need to update and maintain one’s own servers. Small businesses benefit immensely from outsourcing infrastructure needs affordably via the cloud. The cloud can also make it easier for companies to operate internationally because employees and customers can access files and applications from anywhere.

Cloud Computing involves a cloud vendor responsible for hardware purchases and maintenance and provides various options for software, infrastructure, and platform as a service, customizable to architecture needs. Businesses can rent all required services, and most cloud computing services are charged based on usage. The cloud environment provides an easily accessible online portal for the user to manage the computing, storage, network, and application resources.

Cloud computing applies a virtualized platform with elastic resources on demand, dynamically provisioning hardware, software, and data sets. Cloud Computing provides an alternative to the on-premises data center, where businesses must manage everything from purchasing and installing hardware to setting up the network and configuring the firewall, as well as ongoing maintenance throughout its entire lifecycle.

Key Benefits of Cloud Computing include cost reduction by eliminating capital costs of buying hardware and software, speed of resource accessibility within minutes, scalability of resources according to business needs, increased productivity by requiring less operational effort, improved reliability for backup and recovery of data, and strengthened data security through tailored policies, technologies, and controls offered by cloud vendors.
