What is Cloud Computing

Cloud (in computing) refers to the delivery of computing services—like servers, storage, databases, networking, software, and more—over the internet. These services are typically provided by cloud providers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).  Instead of owning and maintaining physical hardware, businesses or individuals can access resources through the internet, often on a pay-as-you go basis.

Types of Cloud. The types of cloud computing environments are categorized based on how they are deployed and who can access them. There are three main types of cloud deployment models: 

 1. Public Cloud . What it is: A cloud infrastructure that is owned and operated by third-party cloud service providers, and it is accessible to the public over the internet.  Who uses it: Multiple customers share the same infrastructure, though data and applications are kept isolated.  Examples: Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP).

 

2. Private Cloud : What it is: A cloud infrastructure that is exclusively used by a single organization. It can be hosted on premises or by a third-party provider, but the environment is private to the organization.  Who uses it: Organizations that require greater control over their data and infrastructure, often for security or regulatory reasons.  Examples: Some businesses host their private cloud internally, while others use solutions like VMware or OpenStack.

3. Hybrid Cloud : What it is: A combination of public and private clouds that allows data and applications to be shared between them. Organizations can use the public cloud for non sensitive operations and the private cloud for sensitive or critical data. Who uses it: Businesses that want the flexibility to scale using public clouds but still need secure environments for certain operations. Eg -An e-commerce business using the public cloud to handle a spike in traffic during a sale, while keeping customer data in a private cloud. 

 

4. Community Cloud : What it is: A cloud infrastructure that is shared by several organizations with similar needs, often from a specific community or industry (e.g., healthcare, government).  Who uses it: Organizations with common concerns, such as compliance, security, and privacy requirements.  Examples: Government agencies sharing cloud infrastructure for managing public services

 

5. Multi-cloud : What it is: The use of multiple cloud services from different providers to prevent vendor lock-in, optimize performance, and increase flexibility. — Who uses it: Organizations that want to diversify their cloud strategy and avoid reliance on a single provider. — Examples: A company might use AWS for hosting, Google Cloud for machine learning, and Microsoft Azure for specific SaaS applications

  Enterprise Data Storage Enterprise data storage in cloud computing is a way for businesses to store their data on remote servers hosted by cloud providers like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud. Instead of keeping data on local computers or physical storage devices (like hard drives) at the office, the data is stored in a data center provided by these companies. Remote Storage : Businesses use the internet to store and access their data in the cloud, which is a collection of remote servers located in large data centers. Scalability : The cloud lets companies store as much data as they need, without worrying about running out of space. They can increase or decrease storage as needed. Cost-Effective : Businesses pay only for the storage they use, saving on the cost of buying and maintaining physical hardware. Accessibility : Data stored in the cloud can be accessed from anywhere, at any time, by author...

                                                Hadoop   Distributed   File system(HDFS)   T he Hadoop Distributed File System (HDFS) is the primary storage system used by the Apache Hadoop framework for storing large datasets across a distributed computing environment. It is designed to handle large-scale data processing across many machines, providing high throughput, fault tolerance, and scalability. HDFS is optimized for large files (typically several gigabytes or terabytes in size) and is ideal for batch processing workloads th at require processing of huge datasets in parallel. Features of HDFS 1.     Distributed Storage : • HDFS stores data across multiple nodes in a Hadoop cluster, distributing files into blocks and storing these blocks across several machines. This helps to ensure scalability and reliability. 2.  ...
