CLOUD COMPUTING

 


Defining Cloud Computing

v  Cloud computing takes the technology, services, and applications that are similar to those on the Internet and turns them into a self-service utility.

v  The use of the word “cloud” makes reference to the two essential concepts:

Abstraction:

v  Cloud computing abstracts the details of system implementation from users and developers.

v  Applications run on physical systems that aren’t specified, data is stored in locations that are unknown, administration of systems is outsourced to others, and access by users is ubiquitous.

 Virtualization:

v  Cloud computing virtualizes  systems by pooling and sharing resources.

v   Systems and storage can be provisioned as needed from a centralized infrastructure, costs are assessed on a metered basis, multi-tenancy is enabled, and resources are scalable with agility.

Use Cases Of Cloud Computing

Cloud computing provides many use cases across industries and various applications:

  1. Scalable Infrastructure: Infrastructure as a Service (IaaS) enables organizations to scale computing resources based on demand without investing in physical hardware.
  2. Efficient Application Development: Platform as a Service (PaaS) simplifies application development, offering tools and environments for building, deploying, and managing applications.
  3. Streamlined Software Access: Software as a Service (SaaS) provides subscription-based access to software applications over the internet, reducing the need for local installation and maintenance.
  4. Data Analytics: Cloud-based platforms facilitate big data analytics, allowing organizations to process and derive insights from large datasets efficiently.
  5. Disaster Recovery: Cloud-based disaster recovery solutions offer cost-effective data replication and backup, ensuring quick recovery in case of system failures or disasters.
  6. Cloud Security

  7. Cloud security recommended to measures and practices designed to protect data, applications, and infrastructure in cloud computing environments. The following are some of the best practices of cloud security:

    • Data Encryption: Encryption is essential for securing data stored in the cloud. It ensures that data remains unreadable to unauthorized users even if it is intercepted.
    • Access Control: Implementing strict access controls and authentication mechanisms helps ensure that only authorized users can access sensitive data and resources in the cloud.
    • Multi-Factor Authentication (MFA): MFA adds an extra layer of security by requiring users to provide multiple forms of verification, such as passwords, biometrics, or security tokens, before gaining access to cloud services.

  PHP WITH OOPS CONCEPT Object-oriented programming is a programming model organized around  Object rather than the actions  and  data rather than logic . Class: A class is an entity that determines how an object will behave and what the object will contain. In other words, it is a blueprint or a set of instruction to build a specific type of object. In PHP, declare a class using the class keyword, followed by the name of the class and a set of curly braces ({}). This is the blueprint of the construction work that is class, and the houses and apartments made by this blueprint are the objects. Syntax to Create Class in PHP <?php   class  MyClass       {            // Class properties and methods go here        }   ?>   Important note: In PHP, to see the contents of the class, use var_dump()...
