Sure, here are short notes on each topic:
a) Hypervisor:
Software that enables multiple operating systems to share a single hardware host.
It allows for the creation and management of virtual machines (VMs), each running its own
operating system.
b) Scalability:
The ability of a system to handle a growing amount of work by adding resources to the
system.
It ensures that a system can maintain or even improve performance as the workload
increases.
c) API (Application Programming Interface):
A set of rules and protocols that allows different software applications to communicate with
each other.
APIs define the methods and data formats that applications can use to request and exchange
information.
d) DJ LaaS (Datacenter and/or Database as a Service):
A cloud computing model where datacenter or database resources are provided to users as a
service.
Users can access and use these resources over the internet on a pay-per-use basis.
e) Private Cloud:
A cloud computing environment that is dedicated to a single organization.
It offers the benefits of cloud computing, such as scalability and flexibility, but within a
private network infrastructure.
f) Cloud Migration:
The process of moving data, applications, and other business elements from an
organization's on-premises infrastructure to the cloud.
It involves planning, assessing, and executing the migration to ensure minimal disruption to
business operations.
g) Access Control:
The process of regulating who can access certain resources or perform certain actions within
a system.
It involves authentication (verifying the identity of users) and authorization (determining
what actions users are allowed to perform).
h) Security Breach:
An incident where unauthorized individuals gain access to confidential or sensitive
information.
Security breaches can lead to data theft, financial losses, and damage to an organization's
reputation.
i) AWS (Amazon Web Services):
A cloud computing platform offered by Amazon.com.
It provides a wide range of services, including computing power, storage, databases, machine
learning, and more, all delivered over the internet.
j) Multitenancy:
A software architecture where a single instance of an application serves multiple users or
"tenants."
Each tenant's data is isolated and securely separated from other tenants, allowing for
efficient resource utilization.

Sure, here are short notes on each topic:
a) Applications of cloud computing:
Infrastructure as a Service (IaaS): Provides virtualized computing resources over the internet.
Platform as a Service (PaaS): Offers a platform allowing customers to develop, run, and
manage applications without dealing with infrastructure.
Software as a Service (SaaS): Delivers software applications over the internet on a
subscription basis.
Big Data Analytics: Cloud computing provides scalable infrastructure for processing and
analyzing large datasets.
Disaster Recovery: Cloud-based disaster recovery solutions offer backup and recovery
services for data and applications.
c) API (Application Programming Interface):
APIs define how software components should interact.
They allow different software systems to communicate and share data.
APIs are used extensively in web development, cloud computing, and integration of various
software systems.
h) Vendor Lock-in:
Vendor lock-in occurs when a customer becomes dependent on a particular vendor's
products or services.
Switching to another vendor becomes difficult and costly due to compatibility issues or
proprietary technologies.
It can limit flexibility and hinder innovation.
i) Grid Computing:
Grid computing is a distributed computing model that involves coordinating and sharing
computing resources across multiple locations.
It allows organizations to harness the computational power of multiple machines to solve
large-scale problems.
Grid computing is used in scientific research, data analysis, and simulations.
g) Service Level Agreement (SLA):
A contract between a service provider and a customer that defines the level of service
expected.
SLAs specify metrics such as uptime, performance, and support response times.
They provide guarantees and penalties for not meeting the agreed-upon service levels.
1. Load Balancing in Cloud:
Load balancing distributes incoming network traffic across multiple servers to ensure
optimal resource utilization and prevent overload.
It improves reliability and scalability by efficiently distributing workloads.
Load balancing is essential in cloud environments to ensure high availability and
performance.
b) VPN (Virtual Private Network):
A VPN extends a private network across a public network, such as the internet.
It enables users to securely access and transmit data over the internet as if they were directly
connected to the private network.
VPNs are commonly used for remote access, privacy protection, and bypassing geo-
restrictions.
e) Cloud Security Risks:
Data Breaches: Unauthorized access to sensitive data stored in the cloud.
Data Loss: Accidental deletion or corruption of data stored in the cloud.
Compliance Violations: Failure to meet regulatory requirements for data protection and
privacy.
Account Hijacking: Unauthorized access to cloud accounts through phishing or credential
theft.
d) Community Cloud:
A community cloud is a cloud computing environment shared by several organizations with
similar computing needs.
It offers benefits of both public and private clouds, such as cost-sharing and resource
pooling.
Community clouds are often used by organizations in the same industry or geographic region
for collaboration and data sharing.
