1. What is Virtualization?
Virtualization alludes to the simulation of an essential thing utilized in computing. Virtualization is anything but an IT solution for enabling multiple services and solutions to operate in one physical location. Virtualization lets a single real server acts like, or host several virtual servers, which operate the same as a real server. You get better utilization of resources, savings of costs and flexibility as you can run different operating systems and applications on the same hardware.
2. Scalability
Scalability is like a balloon which you can add air. You can add air without changing its structure, as you need that more and more air is needed. Scalability refers to the potential for a system to manage an increasing amount of work, i.e., growing data volumes and user loads. You can either add more machines or resources to meet the demand as per your wish.
3. Agility
Agility means the ability to move quickly and easily. Consider a dancer who has the ability to quickly change their feet to keep in sync with the music. Agility in business and technology means being able to respond quickly to changes in the market or changing customer needs. Faster sped upped product delivery makes an organization more competitive.
4. High Availability
High availability is like having a backup generator for your home. It guarantees that important services and systems keep going, even if something's not right. In technician language, high availability means that a system ought to up as much as possible and downtime reduced as much as possible. It is essential for companies that depend on continuous access to their software and information.
5. Fault Tolerant
It would be like juggling without a safety net if we were not fault tolerant. You will not be in trouble even one ball drop. Fault tolerant means when something can still operate properly even with failures. Redundancy and backup systems make sure that if one fails, things don’t stop due to one failure or fault.
6. Global Reach
Expanding your business beyond borders, global reach is all about just that. A local shop is able to sell its products worldwide through an online platform. Global reach with businesses refers to serving and now operating in different nations and regions using technology that connects us. For reference, think of a shop that could only sell to locals. Now, they could sell to anyone worldwide via the internet.
7. What is the difference between Elasticity and Scalability
Scalability can be compared to a flexible building that expands or contracts as per the number of occupants. Elasticity is more about how you can change things quickly and right away. It is like a rubber band which can stretch and shrink often as per the needs. In the world of cloud computing, we have two different terms with two different meanings. They are scalability and elasticity. Elasticity refers to the capacity of resource usage increase or decrease automatically depending on current demand. On the other hand, scalability refers to the ability to grow when needed.
In short, these concepts represent the basis through which modern tech and business functions. These systems make efficient and responsive so that we are geared to tackle any trouble ahead.
