Explain these key concepts;

What is Virtualization

Virtualization
Virtualization allows businesses to use their hardware resources more efficiently, reducing costs and improving performance, It provides greater flexibility in managing and maintaining hardware infrastructure, as virtual machines can be easily created, modified, and moved

Scalability

Scalability
This refers to the ability of a system to handle an increasing amount of work or its potential to accommodate growth. It ensures that the cloud infrastructure can expand or contract resources as needed to meet the demands of the workload.
The ability to automatically increase or decrease resources based on current demands. This is crucial for handling varying workloads efficiently.

Agility

Agility
refers to the ability to quickly and efficiently adapt to changing business needs and market conditions. It allows organizations to rapidly deploy, scale, and manage applications and services with minimal effort and cost.

_High Availability
_

High Availability
refers to the ability of a system to remain operational and accessible even in the event of hardware or software failures. It ensures that services and applications are consistently available to users with minimal downtime.
High Availability is crucial for businesses that rely on cloud services to ensure that their applications and services are always accessible to users.

Fault Tolerant

Fault Tolerant
refers to the ability of a system to continue operating properly even if one or more of its components fail. This ensures that services remain available and reliable, minimizing the impact of hardware or software failures.
Fault tolerance is essential for maintaining high availability and reliability in cloud computing environments.

Global Reach

Global Reach
refers to the ability of cloud services to be accessed and utilized from anywhere in the world. This is made possible by the extensive network of data centers and infrastructure that cloud providers maintain across various geographic locations, it is a fundamental feature of cloud computing, allowing businesses to expand their operations and serve customers worldwide.

What is the difference between Elasticity and Scalability

Elasticity and Scalability

Elasticity and scalability are both crucial concepts in cloud computing, but they serve different purposes:

Scalability: This refers to the ability of a system to handle increased load by adding resources. It can be achieved in two ways:

Vertical Scaling: Adding more power (CPU, RAM) to an existing machine.

Horizontal Scaling: Adding more machines to handle the load. Scalability is about the capacity to grow and manage increased demand over time.

Elasticity: This refers to the ability of a system to automatically adjust resources to match the current demand. It involves dynamically adding or removing resources as needed. Elasticity ensures that the system can handle varying workloads efficiently without manual intervention.

In summary, scalability is about the system's ability to grow, while elasticity is about the system's ability to adapt to changing demands in real-time. Both are essential for optimizing performance and cost in cloud environments
