With the advent of technology, innovation is the upcoming trend. In the times of digitalization, a new concept that has stored up is cloud computing. To put short, 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. By paying for the cloud services, you lower your operating costs. So, if you are a student seeking to pursue a diploma or certificate of cloud computing, this is a brief guide for you.
Benefits of Cloud Computing
As businesses are growing, they’re shifting their focus from the way businesses think about the I.T. resources. Here are some benefits of shifting to cloud computing.
The first benefit of shifting to cloud computing is the reliability of cost. It eliminates the expense of buying hardware and software, setting it up, and running centres. Apart from that, it cuts down on other costs such as electricity, servers, etc. Hence, it is a value for money.
Another ability of cloud computing is the ability to scale elastically. It delivers the right amount of I.T. resources such as adjustable computing power, storage, bandwidth, from anywhere around the world.
Safe and Secure
The cloud computing networks are 100% safe and secure for the transference of data. The service providers will help you seek the availability of a broad set of policies, technologies, and controls. These features secure your data and apps from all the potential threats.
When we compare on-site data centers to cloud computing, the former requires a lot of “racking and stacking”. To specify, it needs the entire hardware setup, software patching, and other time taking chores. While the latter exempt any such tasks, giving more space for other business goals.
Types of Cloud Computing
Now that you have a brief understanding of what is cloud computing, here are the various types of cloud computing that you should know.
The first type of cloud computing is the public cloud. It is owned and operated by a third-party cloud service provider, which in turn delivers the varied computing resources like storage, over the internet. With the help of a public cloud, you can connect all your hardware, software, and other expenditures, which is accessible using a web browser.
Example:- Microsoft Azure is a public cloud.
The second type of cloud computing includes private cloud. The basic users of a private cloud are companies and businesses. In this type, both the services and the infrastructure are safe within the private network.
The third type of cloud computing is a combination of both public and private clouds, inter-connected using technology that allows sharing of data and applications, due to virtual portability of private and public cloud, a hybrid cloud, giving your business greater flexibility, and deployment options.
Types of Cloud Services
Most common types of cloud services include Iaas, PaaS, serverless, and SaaS. To explain all the different cloud services, here are all in brief.
Infrastructure as a Service (IaaS)
In this type of cloud service, you can rent I.T. infrastructure, including:
Servers and virtual machines (V.M.s), storage, networks, operating systems. One gets to buy them from a cloud provider on a pay-as-you-go basis.
Platform as a Service (PaaS)
This cloud computing service is used for development, testing, delivery, and managing software applications. It quickens the development of web and mobile app creation.
The third type of cloud computing is serverless computing. Overlapping with Paas, this cloud computer server helps in building app functionality without wasting time in the management of servers. It helps in setting up, capacity planning, and server management.
Software as a Service (SaaS)
This cloud computing service fulfils the purpose of delivering software applications over the internet on a subscription basis. The service handles the application and looks after the maintenance, like software upgrades and security patching.
Uses of Cloud Computing
To sum up a brief overview of cloud computing, here are some uses of cloud computing. Did you know that knowingly or unknowingly you’re using cloud computing in your everyday life? While watching movies, sending emails, or storing your pictures, you’re making use of cloud computing – here are few other uses of it:
- Storing and back-up of data in a cost-effective way and at massive-scale
- Streaming audio and video from any part of the world
- Build applications and test them at a cheaper cost and time using cloud infrastructure
- Make use of machine learning and artificial intelligence to uncover data insights
