Introduction: What is cloud computing?
Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale.
A cloud service has three characteristic traits: it is sold on demand, it is elastic—meaning that it can scale up or down as needed—and it is provided as a service, meaning that it is managed by the provider.
Cloud computing is using the internet to access programs and data that you would normally store on your computer. Imagine if instead of having a music player like iTunes on your computer, you could go to a website like Pandora and listen to your music there. That’s cloud computing.
The benefits of cloud computing
Cloud computing has a number of benefits for businesses. Perhaps the most obvious benefit is the cost savings. With cloud computing, businesses only pay for the services they use, which can save a lot of money on IT costs.
Another big benefit is that cloud computing can make it easier for businesses to scale up or down their IT usage as needed. This can be a big help for businesses that experience seasonal fluctuations in their demand.
Finally, cloud computing can help businesses be more agile and responsive to change. With cloud-based services, businesses can quickly add or remove features and functionality as needed, without having to go through a lengthy and expensive IT project.
The different types of cloud computing
There are three different types of cloud computing: public, private, and hybrid. Public cloud computing is when a company uses a public cloud provider, such as Amazon Web Services (AWS) or Azure, to provide resources and services. Private cloud computing is when a company uses its own resources, such as servers and storage, to provide services. Hybrid cloud computing is when a company uses both public and private clouds to provide services.
Each type of cloud computing has its own advantages and disadvantages. Public clouds are typically more expensive than private clouds, but they offer more flexibility and scalability. Private clouds are less expensive but can be more difficult to manage. Hybrid clouds offer the best of both worlds but can be more complex to set up and manage.
Which type of cloud computing is right for your business depends on your needs and budget.
How to get started with cloud computing
To get started with cloud computing, businesses first need to identify which workloads can be moved to the cloud. Once workloads have been identified, businesses need to select a cloud provider that meets their specific needs. After selecting a provider, businesses need to set up accounts and configure their environment. Finally, businesses need to migrate their data and applications to the cloud.
The challenges of cloud computing
Cloud computing has become increasingly popular recently, as organizations look for ways to improve efficiency and reduce costs. However, the transition to the cloud can be challenging, and there are a number of potential risks that need to be considered.
One of the biggest challenges is ensuring that data is secure. Cloud providers are responsible for keeping data safe, but they also need to give customers the ability to control access and manage their own security settings. This can be a complex process, and it’s important to ensure all stakeholders are on board with the plan.
Another challenge is managing costs. While cloud services can save money in the long run, they can also be expensive upfront. Organizations need to carefully consider their needs and budget before making the switch.
As more businesses move operations to the cloud, the three biggest providers of cloud computing services are Azure & AWS. Here’s a look at how these three providers stack up.
Azure is a comprehensive set of cloud services that developers and IT professionals use to build, deploy, and manage applications through Microsoft’s global network of data centres. Azure offers both Platforms as a Service (PaaS) and Infrastructure as a Service (IaaS), and supports many different programming languages, tools, and frameworks, including both Microsoft-specific and third-party software.
AWS is the leading cloud platform from Amazon, with over 175 fully-featured services. AWS is used by millions of customers around the world – including the fastest-growing startups, largest enterprises, and leading government agencies – to power their infrastructure needs.
