Cloud Computing
What is Cloud Computing ?
Cloud Computing is when you use a computer/server which is provided to you by someone else. This server has to be accessed over the internet by using a web-based tool for personal or business use. Simply put, Cloud Computing lets you store and access your applications or data over remote computers instead of your computer.
Benefits of Cloud Computing are :
- Pay-per-use Model : You only have to pay for the services you use, and nothing more!
- 24/7 Availability : It is always online! There is no such time that you cannot use your cloud service; you can use it whenever you want.
- Easily Scalable : It is very easy to scale up and down or turn it off as per customers’ needs.
- Security : Cloud Computing offers amazing data security. Especially if the data is mission-critical, then that data can be wiped off from local drives and kept on the cloud only for your access to stop it from ending up in the wrong hands.
- Easily Manageable : You only have to pay subscription fees; all maintenance, up-gradation and delivery of services are completely maintained by the Cloud Provider. This is backed by the Service-level Agreement (SLA).
Three Cloud Computing Deployment Models
Public Cloud
In a public cloud, your applications would reside on a shared infrastructure. Although Cloud Providers provide complete isolation from other users who co-exist on the same hardware, it is advisable not to store any sensitive documents or information on it when using a public cloud.
Private Cloud
A private cloud is not very different from a public cloud, only that the security features vary. In a private cloud, your infrastructure or server will just have your applications. It will be completely isolated from public cloud servers. These servers are commonly used by companies that have sensitive information to store.
Hybrid Cloud
A hybrid cloud is a combination of a public cloud and a private cloud. It provides functionalities of both public and private clouds.So, if a company wants to keep its mission-critical data in a private cloud and run its services and applications on a public cloud, it can make a hybrid integration.
Cloud services are divided into three categories:
A Cloud Provider provides a user with a virtual machine or any other resources without letting the user worry about the physical aspects of the machine. More importantly, the user gets access to the operating system in IaaS. Therefore, you can install/uninstall any software on these servers.
In this service, one does not get access to the operating system. If you need a web server with PHP installed on it, they will give you this web server, without giving you access to the OS. What you get is a dashboard through which you can upload and deploy your files; the rest is managed by the Cloud Provider, i.e., software installation, security patch on OS, etc.
In SaaS, one just gets access to the software which is installed on the server. No dashboard is provided, and no access to the operating system is given, for example, Netflix. You can use Netflix, but you do not have any access to its server or dashboard. You can just use the software.
Cloud Computing Training
With a wide range of Cloud courses already available at a deep technical level, this course is aimed as an introduction to those looking at Cloud Computing from the perspective of a beginner who may have no previous experience of the topic at all. This course covers a wide range of Cloud Computing topics areas providing students with a solid foundation of understanding.
To help you become part of the Cloud revolution, TIEM offers multiple certification courses in Cloud Computing, including AWS, Azure, and DevOps.
These courses also look at the different service models of Cloud Computing, Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) providing examples and differences between each. With all of these different deployment and service options, these courses look at ways other organizations are utilizing the Cloud with some common use cases that you may be familiar with.
The key learning objectives of these courses will enable students to have :
- A clear definition of what Cloud Computing
- A comprehensive understanding of Cloud Computing
- An understanding of Cloud Computing benefits and key concepts
- An understanding of when and where to use it using the appropriate industry models
These courses are intended for anyone who wants to learn about Cloud Computing, and that may have NO or very little of it knowledge of it currently. It’s for those who are looking to learn more about the Cloud to decide if it’s something to adopt within their business, or for those who may be seeking a career move and want to learn the foundation of Cloud principles.
