Explain the concept of virtualization and its benefits in cloud computing
Virtualization is a technology that creates virtual instances of physical hardware resources, such as servers, storage devices, and networks. It allows multiple virtual machines (VMs) to run on a single physical machine, each with its own operating system and applications. This is achieved through aRead more
Virtualization is a technology that creates virtual instances of physical hardware resources, such as servers, storage devices, and networks. It allows multiple virtual machines (VMs) to run on a single physical machine, each with its own operating system and applications. This is achieved through a software layer called a hypervisor, which manages and allocates resources to each VM.
Top 3 Benefits:
Other Benefits:
Isolation and Security, Enhanced Disaster Recovery, Business Continuity and Flexibility etc.
Virtualization is a cornerstone of cloud computing, enabling efficient, flexible, and cost-effective resource management.

Encryption protects data by transforming it into an unreadable format using mathematical algorithms and keys. Here is a simplified process:
The original, readable data that needs to be protected.
A set of complex mathematical rules (e.g., AES, RSA) used to transform plaintext into ciphertext.
A secret string of bits that the algorithm uses to encode the plaintext into ciphertext.
The encrypted, unreadable data resulting from the encryption process.
Types of Encryptions:
– Uses the same key for both encryption and decryption.
– Requires both the sender and receiver to share the key secretly.
– Example: AES (Advanced Encryption Standard).
– Uses a pair of keys: a public key for encryption and a private key for decryption.
– Enhances security by ensuring only the holder of the private key can decrypt the data.
– Example: RSA (Rivest-Shamir-Adleman).
Workflow:
– The sender uses an encryption algorithm and key to convert plaintext into ciphertext.
– The recipient uses the decryption algorithm and the correct key to revert ciphertext back to plaintext.
Use Cases:
Encryption secures data by converting it into an unreadable format using mathematical algorithms and keys.
