Cloud computing services . A cloud service is any resource that is provided over the Internet. The most common cloud service resources are Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS).
Who uses cloud computing services and why?
Corporate and government entities utilize cloud computing services to address a variety of application and infrastructure needs such as CRM, database, compute, and data storage. Unlike a traditional IT environment, where software and hardware are funded up front by department and implemented over a period of months, cloud computing services deliver IT resources in minutes to hours and align costs to actual usage. As a result, organizations have greater agility and can manage expenses more efficiently. Similarly, consumers utilize cloud computing services to simplify application utilization, store, share, and protect content, and enable access from any web-connected device.
How cloud computing services work
Cloud computing services have several common attributes:
- Virtualization– cloud computing utilizes server and storage virtualization extensively to allocate/reallocate resources rapidly
- Multi-tenancy -resources are pooled and shared among multiple users to gain economies of scale
- Network-access – resources are accessed via web-browser or thin client using a variety of networked devices (computer, tablet, smartphone)
- On demand – resources are self-provisioned from an online catalogue of pre-defined configurations
- Elastic -resources can scale up or down, automatically
- Metering/chargeback -resource usage is tracked and billed based on service arrangement
Among the many types of cloud computing services delivered internally or by third party service providers, the most common are:
- Software as a Service (SaaS) – software runs on computers owned and managed by the SaaS provider, versus installed and managed on user computers. The software is accessed over the public Internet and generally offered on a monthly or yearly subscription.
- Infrastructure as a Service (IaaS) – compute, storage, networking, and other elements (security, tools) are provided by the IaaS provider via public Internet, VPN, or dedicated network connection. Users own and manage operating systems, applications, and information running on the infrastructure and pay by usage.
- Platform as a Service (PaaS) – All software and hardware required to build and operate cloud-based applications are provided by the PaaS provider via public Internet, VPN, or dedicated network connection. Users pay by use of the platform and control how applications are utilized throughout their lifecycle.
Benefits of cloud computing services
Cloud computing services offer numerous benefits to include:
- Faster implementation and time to value
- Anywhere access to applications and content
- Rapid scalability to meet demand
- Higher utilization of infrastructure investments
- Lower infrastructure, energy, and facility costs
- Greater IT staff productivity and across organization
- Enhanced security and protection of information assets
Cloud computing service is changing the IT scenario as much as the web did, back in the 1990s. Now a garage setup can deploy its services on the web on a shoe-string budget and still aspire to scale to the size of the Googles, FaceBooks and Amazons of our world.
The deployment platform will scale as and when the business grows, that too, in a granular fashion. For big companies, cloud computing provides enormous advantages of consolidation, manageability, flexibility and sand-boxing.
For many businesses, cloud computing services provide scale-out capability with core infrastructure being on-premise.
Such enormous advantages offered by the cloud is one reason why many companies are adopting the cloud technology and finding ways to migrate applications and infrastructure to the cloud. This is one technology that has created revolutionary changes to the way IT is done today. Cloud has this enormous processing power, virtually unlimited, that can churn data into insights readily, boosting the productivity of any organization that makes use of it.
