What Is The Difference Between Cloud Computing And Virtualization?


Virtualization is a technology that separates hardware functions. Cloud computing, meanwhile, builds on this separation. It is easy to confuse them because in both cases it is a creation of useful environments for abstract resources.

Concrete comparison

With virtualization, a resource can play the role of several resources, while with cloud computing, different services (via a private cloud) or businesses (via a public cloud) have access to the same set of resources that are provided with Automatic way.

 VIRTUALIZATION

Virtualization is a technology that allows you to create multiple simulated environments or dedicated resources from a single physical system. Its software, called a hypervisor, is directly connected to the hardware and allows you to fragment this unique system into several separate secure environments. This is called virtual machines, or VMs. These exploit the ability of the hypervisor to separate resources from the hardware and distribute them properly.

CLOUD COMPUTING

The term “cloud computing” refers to a set of principles and approaches for making computing, networking and storage resources available to users who request them, regardless of the network. services, platforms and applications. These infrastructure, services and applications resources come from a cloud – a pool of virtual resources orchestrated by management and automation software and accessed on demand via open source portals. service. These resources are automatically sized and allocated dynamically.

Which option to choose?

Virtualization

With virtualization, organizations can perform better than using traditional workflows or applications installed directly on their servers. These companies can benefit from a secure environment by leveraging their own hardware and software managed by their IT team. Virtualization products for professionals are fully compatible with traditional workloads because they enable virtual instances of obsolete software to which these workloads are linked.

With virtualization, businesses are able to create more environments and resources from underutilized hardware. They can distribute processor processing capacity, storage and memory in different environments, which means ignoring physical installations and exploiting their hardware in a standardized way. Virtual environments are also protected on their own. Developers can host their sandboxes on the same physical server while isolating them from unauthorized or uncontrolled programs.

Private Cloud

Private clouds enable organizations to make their resources available on demand while complying with security rules or regulations that require limited access, complex encryption, and overall accountability for the source of resources. Private clouds are more suited to stateless, loosely coupled workloads that are characteristic of activities such as development, research, and telecommunications.

Once a company has virtualized its resources, it can use open source tools like OpenStack® to easily deploy private clouds. OpenStack technology relies on APIs (Application Programming Interfaces) to isolate these virtual resources and host them in individual pools used by standard cloud computing tools. The main OpenStack projects support all the infrastructure needed to establish a cloud computing environment: compute, network, storage, identity management and images.

Public Cloud

With a public cloud, companies can reduce their investments in hardware and management teams, since all resources are owned and managed by a third-party vendor. Businesses do not own the gigabytes of storage they use to back up their data. They do not manage the operation of the server farm that hosts the hardware and does not define the procedures for securing or maintaining platforms, applications, or cloud services.

Public clouds allow a customer who wants more resources, platforms, or services to pay a provider by the hour or byte to access what they need when they need it. Infrastructure, resources raw data processing and storage power, or cloud applications are virtualized from vendor-owned hardware and aggregated into data lakes. They are then orchestrated with management and automation software before being transmitted to the client via the Internet or a dedicated network connection. However, public clouds, as we know them today, rarely form an autonomous infrastructure. They are part of a heterogeneous combination of environments that provides enhanced security, better performance, lower costs, and increased availability of infrastructure, services, and applications.
