Study Notes

### Data Management Advantage

Significant Advantage: Cloud computing offers scalability and flexibility for data management, allowing for easy expansion or reduction of storage capacity based on evolving needs without the complexities of physical infrastructure management.
Key Disadvantage: Data security and privacy are significant concerns in cloud computing. Organizations must carefully consider the provider's security measures, data encryption protocols, and legal and regulatory compliance to protect sensitive information.

Cloud Computing Risks

Risk: The dependence on third-party providers for cloud services exposes organizations to potential vendor lock-in, hindering their ability to easily switch providers if desired.

Strategic Edge

Strategic Edge: Cloud computing can offer businesses a competitive advantage by enabling rapid innovation, reducing IT costs, and improving operational efficiency. It allows organizations to respond quickly to market changes and adapt to evolving needs.

Vendor Lock-In

Vendor Lock-In: This refers to the situation where an organization becomes heavily reliant on a specific cloud provider, making it difficult or expensive to switch to alternative services due to factors like proprietary data formats or integrated systems.

Cloud Computing Function

Primary Function: Providing on-demand access to shared computing resources, including servers, storage, databases, networking, software, and analytics, over the Internet. This allows users to access and utilize these resources without the need for direct hardware management.

Infrastructure-as-a-Service

Example: Amazon Web Services (AWS) provides a wide range of IaaS services, allowing users to rent virtual servers (EC2), storage (S3), and networking resources.

Applications without Installation

Service: Software-as-a-Service (SaaS) allows users to access applications without needing to install them locally. Examples include Google Docs, Salesforce, and Dropbox.

Cloud Storage

Characteristic: Data stored in a geographically dispersed network of data centers, ensuring redundancy and resilience to single-point failures.

Virtual Desktop

Description: This refers to a desktop environment that is accessed remotely via a cloud platform, allowing users to work from any location with an internet connection.

Cloud Disaster Recovery

Advantage: It provides organizations with the ability to recover data and applications quickly and efficiently in the event of a disaster, minimizing downtime and potential data loss.

'Access Anywhere'

Implication: This refers to the ability to access SaaS applications from any device with an internet connection, regardless of location.

Scalable Storage Solutions

Service: Cloud storage services, such as Amazon S3 (Simple Storage Service) and Google Cloud Storage, offer scalable storage solutions that can be adjusted based on changing storage requirements.

Platform-as-a-Service (PaaS)

Primary Function: To provide a platform for developers to build, deploy, and manage applications without the need to handle the underlying infrastructure. Examples include Google App Engine, Heroku, and AWS Elastic Beanstalk.

Distributed Computing Limitation

Major Limitation: Before the emergence of cloud computing, distributed computing models often faced challenges in managing resource sharing, synchronization, and data consistency across multiple nodes, making it complex and resource-intensive.

Resource Provisioning

Characteristic: This refers to the ability to provision computing resources on demand, such as servers, storage, and software, without the need for manual intervention by IT staff. This provides agility and scalability for organizations.

Dedicated Cloud

Type: This is a type of cloud that is dedicated to a single organization, offering better control and security compared to shared cloud services.

Cost-effectiveness Improvement

How: Cloud services offer pay-as-you-go pricing models, allowing organizations to pay only for the resources they use, reducing upfront capital expenditure and overall IT spending.

Resource Scaling

Advantage: Cloud computing allows organizations to scale their resources up or down based on their needs, enabling them to handle peak demands or reduce costs during off-peak periods.

Community Cloud

Scenario: In this model, several organizations with shared concerns or goals pool their resources to create a shared cloud environment, offering cost savings and resource optimization.

'Resource Pooling'

Refer: This refers to the practice of sharing physical and virtual resources among multiple users in a cloud environment, optimizing utilization and reducing costs.

Common Cloud Computing Use Case

One Use Case: Data Backup and Recovery: Cloud storage services provide a cost-effective and secure way to store backups of critical data, enabling quick and easy recovery in case of data loss.

Remote Access

Characteristic: Cloud services leverage network protocols that allow users to access them remotely from various devices with internet connectivity.

Non-benefit of Cloud Computing

Option: Complete Control over Infrastructure: While cloud services offer flexibility and scalability, organizations retain limited control over the underlying infrastructure compared to managing their own on-premises systems.

Hybrid Cloud Deployment

Benefit: They allow organizations to combine the benefits of both public and private clouds, utilizing the best of both worlds to meet specific needs and maintain flexibility.

Cloud Computing Data Recovery

Description: Cloud providers typically offer data recovery features that enable users to restore data from backups or snapshots, minimizing data loss and ensuring business continuity.

Cloud-based Development Tools

Advantage: Cloud-based development tools offer collaboration features that allow teams to work on projects simultaneously, regardless of their geographic locations, enhancing team productivity.

Scalability in Cloud Computing

Refer: This refers to the ability of cloud services to adjust the amount of resources (e.g., compute power, storage) provided to users based on their needs, allowing them to scale up or down quickly and efficiently.
