What is Microsoft Azure – A Complete Beginners Guide [2021]

What is Microsoft Azure

What is Cloud Computing?

Cloud computing is a high demand delivery of pay-as-you-need IT services over the internet. Cloud computing allows users to store data in servers instead of buying, maintaining and securing it on data servers.

Cloud computing also allows you to access computing technology services, provides faster innovations, easy digital transformation and flexible resources, and securing data. Cloud computing is cost-efficient as you only pay for what you use. This makes cloud computing help your organisation run smoothly, build IT solutions for your business and scale your business accordingly.

What is Microsoft Azure?

Microsoft Azure is a cloud computing platform launched by Microsoft. Microsoft Azure is a free, open, global, economic and flexible platform that helps IT businesses scaling, developing and smooth the running of the organisations.

Microsoft Azure can be used for services like analytics, Virtual computing, Networking and security, along with being used as supplement or organisation servers. The azure cloud platform is the culmination of more than 200 products that help businesses build solutions that bring the most out of current systems and increase the output of the business to bring stronger ROIs for the organisation.

Types of Azure Clouds

Microsoft Azure is categorised in mainly three types. These types are different from each other based on the service they provide to the organisations. These three types are mainly use-specific for different organisations.

The types include:

1. IaaS

Iaas, also known as the infrastructure as a service, is a platform layer on the basis of foundational aspect. IaaS offers efficient portability of design time. It is recommended for the organisation’s request that requires full control. IaaS provides rapid cloud-based services. It seems that IaaS releases you from the worries that several physical or virtual devices are installed. IaaS helps you connect, monitor, and maintain data centres.

IaaS comes with its limitations, though; it involves a number of security risks due to unpatched servers. IaaS cannot be used in testing and updating servers of organisations that have a defined and set method of organisations.

2. PaaS

PaaS or Platform as a Service is a cloud computing platform that includes an operating system, programming language execution environment, database or web services. Platforms as a service are most commonly used by developers and application service providers. As the name indicates, software development and deployment framework are offered to the client. It is one of the basic principles of Azure that enables the customer to concentrate instead of concerned about hardware and infrastructure on application growth. It also deals with problems with operating systems, networking and servers.

The basic advantages of PaaS are the total cost is low since the resources are allocated on request and servers are added or subtracted automatically. Azure is less insecure, as all known security issues are reviewed automatically on servers. The whole process cannot be seen by the creator, so there is no chance that the data will be violated.

PaaS drawbacks include that there may be portability problems when using PaaS services. The environment at Azure could be different, and the programme needs to be adapted to suit the developers choice.

3. SaaS

SaaS is Software as a Service, includes providing software services to organizations that are managed and hosted centrally. The technology is used as a single version for all customers. There are several instances you can scale up. This helps to ensure the best possible results at all places. The app has a monthly or an annual licence. Dynamics are available as a SaaS, Office, MS Exchange.

In comparison to the conventional models for business installation, SaaS provides several possible advantages such as Lower upfront cost, Quick setup and deployment, Easy upgrades, Accessibility and scalability. While these are the certain pros of SaaS, it comes with its snags like lack of control, security and data concern due to access management, limited range of applications due to certain amounts of application that don’t provide hosting. Connectivity issue that occurs as SaaS is a web delivery service. SaaS can run a little slower than on-site client or server applications, so having the programme out of a local machine in mind is worthwhile.

Azure Key Concepts

 There are a plethora of concepts required to learn in Azure. Below is a list of crucial concepts that one needs to be well-versed with.

Regions

Azure is an international cloud-based platform that is offered around the world in different regions. Initially, you have to define a region when requesting a service, application or VM in Azure. The area chosen for the application is a datacenter.

Datacenter

Conclusion

Cloud computing is an internet-specific concept for data storage and access.

Azure was introduced by Microsoft in February 2010, a cloud computing platform.

Microsoft Azure primarily consists of three kinds of clouds: PAAS, IAAS, SAAS.

The fundamental layer of the cloud platform is IaaS (Infrastructure as a Service).

PaaS is a calculation platform with an operating system, a language programming environment, a database or a web server. SaaS is a centrally hosting and operated software (Software as a service).

Some of the main words Azure use include Datacenters and regions, Azure portal, Resources, Resource classes, Resource Manager models, Azure PowerShell, Azure Command Line Interface(CLI). Computing, storage, database, monitoring, maintenance systems, content delivery networks, azure networking, Web and Mobile services, etc., are key components of Microsoft Azure.
