What are the Basic Types of Cloud?

The types of cloud can be broken down into the following four broad categories:


1. Public Cloud
In this model, a third party provides resources such as storage, compute or network etc. to a large number of enterprises. The public cloud is based on the principle of shared or pooled resources.
2. Private Cloud
In the case of private cloud, the deploying entity sets up an exclusive data center on premise, which then delivers the above resources. In some cases, a private cloud may also involve colocation to curtail the exorbitant hardware costs.
3. Hybrid Cloud
A hybrid cloud is a combination of on premise and third-party data centers. In hybrid cloud, workloads are systematically allocated to both the clouds based on certain considerations that revolve around cost, efficiency and regulatory compliance.
4. Multi Cloud
The possibilities in case of multi cloud are limitless. This is a combination of both public and private cloud or the integration of multiple public cloud providers. This cloud model is difficult to integrate and manage, but also pays handsome dividends.

What is the difference between business intelligence (BI) & analytics?

With BI getting more prominent, there has been a rise in confusion between business intelligence (BI) and business analytics (BA).

Business Analytics: For future business operations.
Field:
Business Intelligence: BI comes under Business Analytics.
Business Analytics: Contains data warehouse, information management etc.

What are the Benefits of Cloud Computing?

· No need to procure and maintain on premise data centers

· Cloud services are compatible with multiple devices and operating systems

· You can enjoy instant scalability, thus improving organizational agility

· Cloud environments are generally more secure as compared to on premise ones

· Enterprise data is centralized, making it easy to secure it and maintain backups

· Accelerate the on-boarding time of employees, especially remote workers

Who are the Target Users of BI?

· Top management, Strategic planners and key business users

· Analysts

· Line workers

· Customers/Supplier

Is the Cloud a Secure Ecosystem?

Public Cloud Service Providers (CSP) adopt a multi layered approach to security. Measures such as firewalls, intrusion detection and prevention, encryption, user authentication, malware and ransomware protection fortify the security of cloud.

What is a Data Warehouse?

A data warehouse, also known as an enterprise data warehouse, is a system used for reporting and data analysis and is considered a core component of business intelligence. DWs are central repositories of integrated data from one or more disparate sources.

What is a Firewall?

It is a security system designed for the network. A firewall is set on the boundaries of any system or network which monitors and controls network traffic. Firewalls are mostly used to protect the system or network from malware, worms, and viruses. Firewalls can also prevent content filtering and remote access.

What is a VPN?

VPN stands for Virtual Private Network. It is a network connection method for creating an encrypted and safe connection. This method protects data from interference, snooping, censorship.

What is meant by data leakage?

Data leakage is an unauthorized transfer of data to the outside world. Data leakage occurs via email, optical media, laptops, and USB keys.
