Microsoft Azure: the main benefits of the Public Cloud.
Microsoft Azure is the set of Cloud Services that helps organizations address professional challenges. A cloud platform created to allow organizations to create, deploy and manage services and solutions that previously required investment and deployment in local services and infrastructure.
Using cloud-based services allows you to accurately size the resources you need with complete flexibility and scalability: with the result that you only spend on the resources that are truly useful and can increase or decrease them at any time.
From this point of view, we talk about IaaS and PaaS solutions where what you pay for is the use of a service, thus reducing the business costs related to the production, maintenance and management of local infrastructures.

Azure cloud represents a big change from the traditional view of companies regarding IT resources which brings with it a number of benefits:
- Costs – cancellation of CAPEX expenses associated with hardware and software purchases
- Scalability – flexible scaling of IT resources
- Productivity – Dramatically reduce all operations-related activities to allow IT teams to focus their time on achieving business goals
- Performance – speed and efficiency delivered by state-of-the-art hardware decreases latency and enables economies of scale
- Reliability – reduce the cost of data backup, disaster recovery and business continuity by mirroring data across multiple redundant sites in the provider’s network.
- Security – ongoing technologies and controls strengthen overall security behavior by protecting data, apps and infrastructure from potential threats.
- Types of cloud services: IaaS, PaaS, serverless and SaaS – Most cloud computing services fall into four broad categories: distributed infrastructure as a service (IaaS), distributed platform as a service (PaaS), serverless computing and software as a service (SaaS). This is sometimes referred to as a cloud computing “stack,” as these categories are based on each other. Understanding these solutions and their differences makes it easier to achieve business goals.
Distributed infrastructure-as-a-service (IAAS)
This is the basic category of cloud computing services. With an IaaS solution, you have the option to lease the IT infrastructure: servers and virtual machines (VMs), storage resources, networks, and operating systems are then released by a cloud service provider with payment based on consumption.
Distributed Platform as a Service (PaaS)
PaaS (distributed platform as a service, Platform as a Service) refers to cloud computing services that provide an on-demand environment for developing, testing, deploying, and managing software applications. A PaaS solution is designed to enable developers to more easily and quickly create Web or mobile apps without having to worry about configuring or managing the underlying server infrastructure, storage network and databases required for development.
Overlapping with the PaaS model, serverless processing focuses on app creation functionality without requiring you to spend time managing the necessary servers and infrastructure. The cloud service provider automatically handles configuration, capacity planning and server management. Serverless architectures are event-driven, offer high scalability, and use resources only when a specific function or trigger occurs.
Software as a Service (SaaS)
SaaS (Software as a Service) is a method of distributing software applications over the Internet, on demand and usually on a subscription basis. With a SaaS solution, cloud service providers host and manage the software application and underlying infrastructure, and take care of maintenance tasks, such as software updates and security patching. Users connect to the application via the Internet, typically with a Web browser on their phone, tablet or PC.
