What exactly is cloud computing?
Cloud computing refers to the on-demand delivery of computing resources like hardware, storage, databases, networking, & software to businesses & individuals through a network, typically the internet. Cloud computing allows organizations to access & store information without having to manage their own physical devices or IT infrastructure.
As more & more data is created & shared, & consumers want increased access to online services, it has become challenging for companies to continue operating on in-house computing servers.
Similar to accessing your email inbox online through a web browser, cloud computing enables companies to manage resources & applications from anywhere with an internet connection. Cloud services are also usually maintained by a third-party provider, which allows IT teams to rapidly adjust compute & storage without upfront infrastructure costs or setting up more systems & apps.
You can choose public, private or hybrid cloud deployments & service models based on the level of flexibility, control & management you require. The three main types of cloud service models are:
- Infrastructure as a service (IaaS) – on-demand access to computing, storage, networking & virtualization
- Platform as a service (PaaS) – hardware & software resources required for developing cloud apps
- Software as a service (SaaS) – full application stack as a cloud service, including maintenance & management from underlying infrastructure to application software
What are the various categories of cloud computing?
There are four main categories of cloud computing: public, private, hybrid, &multicloud.
Public cloud
Public cloud refers to an IT model where computing services & infrastructure are provided by a third-party vendor over the internet, & shared among multiple organizations & users. Major cloud providers offer services like Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), & Software-as-a-Service (SaaS) on a pay-per-use or monthly subscription basis. Leading public cloud platforms include Amazon Web Services (AWS), Microsoft Azure, Google Cloud, Alibaba Cloud, & IBM Cloud.
Private cloud
A private or internal cloud is where the IT infrastructure like hardware & software is dedicated solely to one organization, unlike public cloud where resources are shared. Private cloud is suitable for organizations that prioritize regulatory compliance, security, & control. Traditionally private cloud is hosted on a company’s own data center using its hardware, but can also be outsourced to a third-party provider for remote management.
Hybrid cloud
Hybrid cloud combines both public & private cloud environments. Businesses use this model to expand their compute capacity by leveraging public cloud when private cloud peaks. Hybrid enables scaling compute up or down based on traffic or demand fluctuations, eliminating the need to purchase & maintain new servers. This saves cost, time & effort.
Multicloud
Multicloud involves using multiple public or private clouds, or a mix of both, from different vendors. Multicloud allows selecting the optimal services from various cloud providers based on budget, requirements, geography etc. It enables using separate clouds for different functions like development, backup, analytics & so on.
What is the primary benefit of using cloud computing services?
Accessibility from anywhere, using any device
Cloud computing allows access to information & applications from any location using any internet-enabled device. Employees at different branches or offices can log in & access updated data. This ensures all employees stay current whether they are in the office or traveling.
Eliminate most hardware & software
With cloud computing, businesses no longer need their own servers, cables, routers, etc. Depending on the provider, cloud platforms manage the IT infrastructure for a monthly fee. This significantly reduces expenses, which is vital for any business.
Centralized data security
Cloud computing centralizes data backup in provider data centers. This eliminates the need for individual or team backups onsite or offsite. If any one backup fails, providers can restore from other cloud copies. These are continuously updated with new data.
Teams can use cloud security like encryption & two-factor authentication for more privacy than self-managed servers. Oracle uses security-first architecture with automated protection.
Higher performance & availability
Using cloud resources together provides greater performance than dedicated servers. Cloud increases input/output operations per second (IOPS). Oracle delivers up to 20X the IOPS of Amazon Web Services.
Cloud services offer high availability across facilities, preventing downtime. Providers manage updates & fixes transparently.
Quick application deployment
Cloud applications deploy quickly without procuring hardware or waiting on IT. Services support different infrastructure technologies.
Instant business insights
Cloud platforms enable accessing data instantly for better & quicker decisions using historical data.
Business continuity
Cloud computing facilitates disaster recovery & business continuity. Infinite storage & remote activation ensure backup if needed.
Cost savings
While initial investment is required, long-term savings from avoiding hardware & data centers outweigh costs. No upfront fees allow testing before buying. Oracle provides value & flexibility.
Virtualized computing
Cloud computing suits virtual environments. Resources scale effortlessly to meet growing demands without downtime. Businesses expand capabilities without more staff or capital.
Greener technology
Cloud computing reduces energy use & carbon footprint by up to 90% over traditional IT. Shared services avoid resource-intensive infrastructure.
What are the three distinct categories of cloud computing services?
There are three main types of cloud computing services: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), & Software-as-a-Service (SaaS).
IaaS refers to a cloud service where cloud providers supply & administer virtual computing infrastructure over the internet. Rather than constructing an internal IT infrastructure, businesses can access essential resources like operating systems, networking, storage space, & development tools on demand. This reduces hardware & software expenses & minimizes the load on IT staff.
PaaS enables businesses to focus on the development, deployment, & management of software applications & services without having to worry about the fundamental infrastructure, since cloud providers handle the heavy lifting. With PaaS, developers & programmers get access not just to IT infrastructure, but also to application/software platforms & solution stacks.
SaaS provides businesses with ready-to-use software delivered to users over the internet. All underlying infrastructure, including hardware, software, data storage, patch management, & hardware/software updates are handled by SaaS providers. SaaS utilizes a subscription-based model, requiring businesses to subscribe to the services they want to use.
Users can access SaaS applications directly through web browsers, eliminating the need to download or install them. SaaS enables users to access web-based solutions anywhere with an active internet connection. Well-known SaaS solutions include Microsoft 365, Google Workspace, &Salesforce.
What are cloud computing services & can you provide an example?
Cloud computing services provide different platforms like SaaS, PaaS, & IaaS. The IaaS platforms offer compute resources, file storage, & networking capabilities. PaaS solutions, such as Google App Engine, give developers the necessary tools to build & test new applications. SaaS cloud solutions, for example Slack, allow users to access software from anywhere around the world.
