Security+: Cloud and Virtualization Concepts

The CompTIA Security+ certification has become a worldwide standard for recognizing competence in IT security and cloud and virtualization

Virtualization or virtualisation is the act of creating a virtual version of something, including virtual computer hardware platforms, storage devices, and computer network resources. Virtualization enables organizations to run more than one virtual system and multiple operating systems and applications on a single server.

In the past organisations hosted their Virtualization environment onsite. Today these organisation use cloud computing.

Cloud Computing comes in many different formats such-as Platform as a Service (PaaS), Software as a Service (SaaS), Infrastructure as a Service (IaaS), Private Cloud, Public Cloud, Hybrid and Community Cloud. Cloud environments is all provided using
Virtualization.

Platform as a service (PaaS) is a complete development and deployment environment in the cloud, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications.

Software as a service (SaaS) is a software licensing and delivery model in which software is licensed on a subscription basis and is centrally hosted.

Infrastructure as a service (IaaS) is a type of cloud computing service that offers essential compute, storage, and networking resources on demand, on a pay-as-you-go basis.

Benefits of cloud computing

1. Scalability: every application or piece of infrastructure can be expanded to handle the increased load.
2. Control options: organizations can determine a better level of control with service options. These include software as a service (SaaS), platform as a service (PaaS) and infrastructure as a service (IaaS).
3. Security features: virtual private cloud, encryption and API keys help keep data secure.
4. Accessibility: applications and data are accessible from any device with an internet connection.
5. Better data security: hardware failures don’t result in data loss because these cloud solutions implemented networked backups.
6. Speed to market: developing in the cloud allows users to get their applications to market quickly.
7. Savings on equipment: cloud computing uses remote resources, saving organizations the cost of servers and other physical equipment.
8. Pay structure: users pay only for the resources they use.
9. Regular updates: service providers regularly update offerings to give users the most up-to-date technology.
