Let us get started then

Why Cloud Computing?

10 years back, companies were storing everything in-house i.e on their own servers. But over the years with internet speed becoming better, people discovered a new way to store everything, the “Cloud” way! What is Cloud? To understand What is Cloud, let’s first understand why it came into the picture!

Before “Cloud”, companies were storing everything offline i.e hosting websites on their on-premise servers, and adding more servers whenever required. But, there were some problems with this kind of setup. What were these problems? Let’s discuss them using an example in this Azure Tutorial Blog:

  • You own a company which runs a very successful website and let’s imagine the “cloud concept” was not introduced at this time. Therefore your website was hosted on the on-premise servers. Seems normal, right?
  • One fine day, you added a new feature to your website which became a hit over night. Now, your traffic increased multi-folds and the inevitable happened, your website crashed!
  • Woah! That hurts, isn’t it? Well you obviously couldn’t have foreseen this, and even if you did, there was no way you could have spent and bought the required servers, in such a short time. Why? Well, servers are not cheap guys, they are very VERY expensive.

Cloud Problems - Azure Tutorial - Edureka

Let’s say you can afford these many servers, but are you sure about experiencing this much traffic everyday? After you bought the servers and the next day your traffic dropped, what will you do with these servers now? They will be idle most of the time, and hence they become a bad investment on your part.

Now with this example, let’s summarize the problems with the private model in this Azure Tutorial:

  1. This setup is expensive.
  2. Your servers will be idle most of the time.
  3. Every machine is bound to fail one day, maintaining these many servers becomes a tedious task.

To handle these problems we had to come up with a new model of infrastructure. Hence, we came up with Cloud. With cloud computing, all these problems were solved! How?

  • Put your data on Cloud Servers and you are set! No more buying expensive servers.
  • Scalability! Your server capacity will scale up or scale down according to the traffic, that too automatically.
  • Your cloud provider will manage your servers, hence no worries about the underlying infrastructure.

We now understand in this Azure Tutorial, why cloud computing was needed, let’s go ahead and understand what it is exactly?

Azure Tutorial: What is Cloud Computing?

It is the use of remote servers on the internet to store, manage and process data rather than a local server or your personal computer.

Store: Store large or small files on the cloud, which you can access on the go!

Manage: Manage your data with optimized databases on the cloud.

Process: With scalable compute power on the cloud, you can process any amount of data in moments!

Cloud - Azure Tutorial - Edureka

So basically, all these tasks i.e “store, manage and process”, rather than doing it on your personal computer or your private datacenter, you are doing it on the public cloud, and this is what Cloud Computing is all about.

There are basically 3 categories in cloud computing:

  • SaaS (Software as a Service)
    • It allows companies to use software without purchasing them, which reduces the expenditure of the company drastically, since they are already installed on the cloud servers they can be quickly deployed and therefore saves time.
  • PaaS (Platform as a Service)
    • It allows developers to build applications, collaborate on projects without having to purchase or maintain infrastructure.
  • IaaS (Infrastructure as a Service)
    • It allows companies to rent servers, storage space, etc. from a cloud provider.

Service Models - Azure Tutorial - Edureka

Since, there are so many benefits of Cloud Computing, therefore it was just a matter of time that companies understood its market potential. Hence, we have a lot of Cloud Providers today.

Today, in this blog on Azure Tutorial, I will be discussing about Microsoft Azure which is an IaaS. First, let’s discuss why you are learning Microsoft Azure.

Azure Job Trends

The demand for Azure Solutions Architect as can be seen in the trends, and hence it makes sense for you to upgrade yourself to be the master of cloud.

Let’s go ahead in this Azure Tutorial and understand What is Microsoft Azure?

What is Microsoft Azure?

We discussed about the cloud services in this Azure Tutorial right? A company which provides these cloud services, is called a cloud provider. Now, there are a lot of cloud providers out there, one of them Microsoft Azure.

Microsoft Azure is a cloud computing platform created by Microsoft which developers and IT professionals use to build, deploy and manage applications through their global network of datacentres.

What is Azure - Azure Tutorial - Edureka

Azure Services

Microsoft Azure provides various services that would help you in computing in one way or the other and these services are clubbed into domains. Here are a few notable domains:

  • Compute
    It is used to process data on the cloud by making use of powerful processors which serve multiple instances at a time.
  • Storage Services
    The storage as the name suggests, is used to store data in the cloud with the ability to scale as and when required. This data can be stored anywhere.
  • Database
    The database domain is used to provide reliable relational and non relational database instances managed by Azure.
  • Networking
    It lets you connect to cloud and on-premise infrastructure and services to get great user experience

There are plethora of services you would wanna checkout, you may checkout this stack of Azure Resources to no more.

Azure Pricing

Azure Pricing - Azure tutorial - Edureka

This might easily be one of the most popular reasons to learn Microsoft Azure and also use it. For people who are new and want to learn about the technology, Azure provides you free Credits which can be used to access Azure services for free for a short duration. This is sufficient to get one started.

Azure is extremely flexible and offers a pay-as-you-go approach which can greatly help serve your business needs. Flexible pricing greatly supports up-scaling or down-scaling the architecture as per the needs.

This was about Azure pricing. Now, let us continue with this Azure tutorial and discuss what kind of Certifications Azure has to offer?

Azure Certifications

Microsoft Azure aims to fill in the skill gap between the industry requirement and the resources available and to do that they have taken following measures:

  • Introduce Roles Based Certifications
  • Provide Aligned Experience
  • Make Certifications simple and discover able
  • Have more industry recognition to the certifications offered

In the process the have classified Azure Certifications into three major categories, which are:

These certifications have levels where one has to first get an associate level certification and then use it as a stepping stone for Advanced level certification.
