Microsoft Azure is a cloud computing platform from Microsoft

The disadvantage of IaaS is more effort required for server management. This is particularly noticeable when there are security gaps in programs. Program bug lists must be monitored and security updates must be installed. This must all be done by in-house teams rather than by the cloud provider.

The advantage is the flexibility to adapt environments quickly and individually. IaaS is ideal for companies that do not have or do not want to have their own data center.

PaaS (Platform as a Service) is a service in which the cloud provider manages the hardware and software in its own infrastructure and makes it available to the user as an integrated solution.

This solution offers advantages for development teams that are only cameroon consumer email list​ focused on developing their own application. Examples are OpenShift, Heroku and Microsoft Azure App Services. PaaS is a good solution for teams that are relatively small and do not have any infrastructure specialists.

SaaS (Software as a Service) is the highest form of managed cloud. At this level, complete programs are provided that only need to be managed by the user.

An example of SaaS is Microsoft Office, as a company only has to manage its users and everything else is automated. No servers in the data center and no software updates on the server are necessary. The application does not have to be implemented, but is available as a service.

This makes SaaS ideal for smaller companies or for software that does not need to be customized or is only used occasionally.

What is Azure?
primarily for companies that develop software. Microsoft Azure offers IaaS, PaaS and SaaS structures and developers and companies can easily scale.

Microsoft Azure is one of the fastest growing cloud computing providers in recent years, as can be seen in the following image. Amazon dominates the market with more than 30%, but Microsoft has placed a great deal of focus on Azure in recent years and has managed to grow quickly in the market.

Azure Regions
Azure Regions are Microsoft data centers. The price varies depending on location and requirements. For time-critical infrastructure, it is advantageous to have low latency (local proximity to the company location). However, if you are training a deep learning model, for example, it does not matter how far away the server is. In this case, it is better to choose a cheaper data center.

Azure Regions is designed with redundancy and reliability in mind; this means that availability zones provide protection against local outages. This makes it possible to automatically move infrastructure that is not available to other servers without long downtimes. This is a huge advantage, as outages are completely prevented. This is why banks always need multiple data centers that are 200 km or more apart (geo-redundancy). Although this service costs extra, it is important for companies, as geo-redundancy is significantly cheaper than setting up a second data center.
