What is Cloud Computing?
Understanding the types of cloud computing resources can be time-consuming and costly. Enterprises need to buy physical servers and other infrastructure through procurement processes that can take months, and support the architecture of cloud computing. The acquired systems require a physical space, typically a specialized room with sufficient power and cooling. After configuring and deploying the systems, enterprises need expert personnel to manage them.
This long process is difficult to scale when demand spikes or business expands. Enterprises can acquire more computing resources than needed, ending up with low utilization numbers.
Cloud computing addresses these issues by offering computing resources as scalable, on-demand services. Learn more about Google Cloud, a suite of cloud computing service models offered by Google.
Cloud computing is the on-demand availability of computing resources (such as storage and infrastructure), as services over the internet. It eliminates the need for individuals and businesses to self-manage physical resources themselves, and only pay for what they use.
The main cloud computing service models include infrastructure as a service offers compute and storage services, platform as a service offers a develop-and-deploy environment to build cloud apps, and software as a service delivers apps as services.
Understanding how cloud computing works
Types of cloud computing deployment models
What are the types of cloud computing services?
Infrastructure as a service (IaaS)
Platform as a service (PaaS)
Software as a service (SaaS)
Due to the architecture of cloud computing, enterprises and their users can access cloud services from anywhere with an internet connection, scaling services up or down as needed.
Enterprises can develop new applications and rapidly get them into production—without worrying about the underlying infrastructure.
It offers strategic value
Because cloud providers stay on top of the latest innovations and offer them as services to customers, enterprises can get more competitive advantages—and a higher return on investment—than if they’d invested in soon-to-be obsolete technologies.
Enterprises often ask, What are the security risks of cloud computing? They are considered relatively low. Cloud computing security is generally recognized as stronger than that in enterprise data centers, because of the depth and breadth of the security mechanisms cloud providers put into place. Plus, cloud providers’ security teams are known as top experts in the field.
Whatever cloud computing service model is used, enterprises only pay for the computing resources they use. They don’t need to overbuild data center capacity to handle unexpected spikes in demand or business growth, and they can deploy IT staff to work on more strategic initiatives.
How cloud computing can help your organization
The pace of innovation—and the need for advanced computing to accelerate this growth—makes cloud computing a viable option to advance research and speed up new product development. Cloud computing can give enterprises access to scalable resources and the latest technologies without needing to worry about capital expenditures or limited fixed infrastructure. What is the future of cloud computing? It’s expected to become the dominant enterprise IT environment.
If your organization experiences any of the following, you’re probably a good candidate for cloud computing:
- High business growth that outpaces infrastructure capabilities
- Low utilization of existing infrastructure resources
- Large volumes of data that are overwhelming your on-premises data storage resources
- Slow response times with on-premises infrastructure
- Delayed product development cycles due to infrastructure constraints
- Cash flow challenges due to high computing infrastructure expenses
- Highly mobile or distributed user population
These scenarios require more than traditional data centers can provide.
Many organizations, including those in retail, have wildly varying needs for compute capacity. Cloud computing easily accommodates these fluctuations.
Rather than building more data centers to ensure continuity during disasters, businesses use cloud computing to safely back up their digital assets.
Cloud computing helps overloaded data centers by storing large volumes of data, making it more accessible, easing analysis, and making backup easier.
Cloud computing offers enterprise developers quick access to tools and platforms for building and testing applications, speeding up time to market.
Big data analytics
Cloud computing offers almost unlimited resources to process large volumes of data to speed research and reduce time to insights.
