• ELASTICITY - Ability to acquire resources as you need them and release resources when you no longer need them.
• Understand Elasticity with a simple real-life example -What is Elasticity?

• Scalability is used to meet the static increase in the workload.
• Scalability is long-term planning and adopted just to deal with an expected increase in demand.

In the event of a failure, the Azure infrastructure (the Fabric Controller) reacts immediately to restore services and infrastructure. For example, if a virtual machine (VM) fails due to a hardware failure on the physical host, the Fabric Controller moves that VM to another physical node based on the same hard disk stored in Azure storage. Azure is similarly capable of coordinating upgrades and updates in such a way as to avoid service downtime. So, Azure is fault-tolerant.

Azure datacenters become unavailable

Azure does not necessarily allow you to reduce the level of IT staffing that is required to maintain on-premises applications and services. Although there is no need for hardware IT support in a public cloud deployment, the company still needs IT personnel to maintain its on-premises applications and services.

Azure allows you to pay for servers monthly based on usage, rather than pay upfront for physical hardware. CapEx refers to money that is spent upfront on infrastructure hardware such as routers, switches, and servers. With a public cloud deployment in Azure, you only need to pay for the usage of these devices. This eliminates CapEx costs. With a hybrid cloud deployment in Azure, you can lower CapEx costs because you only need to pay for devices that are on-premises.

Azure does not reduce the amount of maintenance that is associated with configuring firewalls, which would reduce costs. Although Azure eliminates the need to perform physical cabling of networks, it still requires you to configure the software.

Azure does not allow you to pay annually to reduce the overall costs that are associated with its platform-as-a-service (PaaS) offerings. It allows you to pay annually for some infrastructure-as-a-service (IaaS) offerings, such as virtual machines (VMs), through reserved VM instances.

This is a direct conceptual question. In cloud computing, we pay as per our usage rather than paying upfront.

With CapEx, your costs are fixed. CapEx is an upfront cost, and you know exactly how much is being spent. Buying the servers and equipment for a data center is a CapEx.

Using CapEx for infrastructure spending is not a good idea when the demand fluctuates or is unknown. Quite on the contrary, CapEx is appealing when you need to predict the cost before the start of a project and plan your expenses accordingly. When the demand fluctuates or is unknown, you should consider OpEx.
