What is Microsoft Azure?
Azure is an ever-expanding set of cloud computing services to help your organization meet its business challenges. Azure gives you the freedom to build, manage and deploy applications on a massive, global network using your preferred tools and frameworks.
Azure Clouds Types :
The three main service models of cloud computing are:
IaaS (Infrastructure as a Service)
Infrastructure as a service (IaaS) is an instant computing infrastructure, provisioned and managed over the internet. It’s one of the four types of cloud services, along with software as a service (SaaS), platform as a service (PaaS), and serverless.
IaaS quickly scales up and down with demand, letting you pay only for what you use. It helps you avoid the expense and complexity of buying and managing your own physical servers and other datacenter infrastructure. Each resource is offered as a separate service component, and you only need to rent a particular one for as long as you need it. A cloud computing service provider, such as Azure, manages the infrastructure, while you purchase, install, configure, and manage your own software—operating systems, middleware, and applications.
1. High availability.
2. Strong security profile.
3. Scalability options.
5. Multiple Redundancies in place to maintain data access.
6. It’s allows use any framework, language, or tool.
7. access to app connectors.
8. Automate repetitive tasks.
9. It’s allows businesses to build a hybrid infrastructure.
10. Access to a rich set of artificial intelligence services.
1. Have to manage Azure to make it effect.
2. Have platform expertise available.
3. It insist you to put all your eggs into one basket.
4. Speed can be an issue for some businesses.
5. Ease access may be problem for few businesses.
6. Plenty of security risks from unpatched servers
7. Some companies have defined processes for testing and updating on-premise servers vulnerabilities. This cannot be done with Azure.
PaaS ( Platform-as-a-Service )
Platform as a service (PaaS) is a complete development and deployment environment in the cloud, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications. You purchase the resources you need from a cloud service provider on a pay-as-you-go basis and access them over a secure Internet connection.
Like IaaS, PaaS includes infrastructure—servers, storage and networking—but also middleware, development tools, business intelligence (BI) services, database management systems and more. PaaS is designed to support the complete web application lifecycle: building, testing, deploying, managing and updating.
PaaS allows you to avoid the expense and complexity of buying and managing software licenses, the underlying application infrastructure and middleware, container orchestrators such as Kubernetes or the development tools and other resources. You manage the applications and services you develop and the cloud service provider typically manages everything else.
- Cut coding time.
- Add development capabilities without adding staff.
- Develop for multiple platforms—including mobile—more easily.
- Use sophisticated tools affordably.
- Support geographically distributed development teams.
- Efficiently manage the application lifecycle.
- Portability issues can occur when you use PaaS services
- There may be different environment at Azure, so the application needs to adapt accordingly.
- Risks of lock-in
- Limited Scalability
- Mix-up Complexity
SaaS (Software as a service)
Software as a service (SaaS) allows users to connect to and use cloud-based apps over the Internet. Common examples are email, calendaring and office tools (such as Microsoft Office 365).
SaaS provides a complete software solution which you purchase on a pay-as-you-go basis from a cloud service provider. You rent the use of an app for your organisation and your users connect to it over the Internet, usually with a web browser. All of the underlying infrastructure, middleware, app software and app data are located in the service provider’s data center. The service provider manages the hardware and software and with the appropriate service agreement, will ensure the availability and the security of the app and your data as well. SaaS allows your organization to get quickly up and running with an app at minimal upfront cost.
- Pay only for what you use..
- Use free client software.
- Mobilise your workforce easily.
- Access app data from anywhere.
- Insufficient Data Security. This is one of the top concerns for companies who are looking to opt for a SaaS-based application model.
- Difficulty with Regulations Compliance.
- Cumbersome Data Mobility.
- Low Performance.
- Troublesome Software Integration.
Azure key Concepts are :
|Regions||Azure is a global cloud platform which is available across various regions around the world. When you request a service, application, or VM in Azure, you are first asked to specify a region. The selected region represents datacenter where your application runs.|
|Datacenter||In Azure, you can deploy your applications into a variety of data centers around the globe. So, it is advisable to select a region which is closer to most of your customers. It helps you to reduce latency in network requests.|
|Azure portal||The Azure portal is a web-based application which can be used to create, manage and remove Azure resource and services. It is located at https://portal.azure.com.|
|Resources||Azure resource is an individual computer, networking data or app hosting services which charged individually. Some common resources are virtual machines( VM), storage account, or SQL databases.|
|Resource groups||An Azure resource group is a container which holds related resource for an Azure solution. It may include every resource or just resource which you wants to manage.|
|Resource Manager templates||It is a JSON which defines one or more resource to deploy to a resource group. It also establishes dependencies between deployed resources.|
|Automation:||Azure allows you to automate the process of creating, managing and deleting resource by using PowerShell or the Azure command-line Interface(CLI).|
|Azure PowerShell||PowerShell is a set of modules that offer cmdlets to manage Azure. In most cases, you are allowed to use, the cmdlets command for the same tasks which you are performing in the Azure portal.|
|Azure command-line interface(CLI)||The Azure CLI is a tool that you can use to create, manage, and remove Azure resources from the command line.|
|REST APIs||Azure is built on a set of REST APIs help you perform the same operation that you do in Azure portal Ul. It allows your Azure resources and apps to be manipulated via any third party software application.|
