CLOUD COMPUTING

Let’s begin from scratch AWS is Abbreviated as “Amazon Web Services” it was Founded on 3rd March 2006 In Simple Words AWS Means Cloud Computing Platform So what does cloud computing means?? It is nothing but distribution of different Services through the Internet

Fun Facts: Some might think a cloud storage is an Imaginary Server!!! But What if I tell you It’s Just storing the data’s in Someone else Computer 😊

Now Back to Basics Like AWS we have other Clouds too such as Microsoft Azure, Google Cloud Platform, IBM Cloud, Oracle and Alibaba These all comes under the Category Called “Public Cloud” Some of the Main Characteristics of Public Cloud are • Scalability • Reliability • Inexpensive • Location Independent • Supports Multiple Customers • Fully customizable • Robust Management Like Public Cloud we have Private and Hybrid Cloud So Let me Explain them in one liner for your better understanding A Private Cloud is defined as everything behind an Organization’s wall

Where as the Hybrid Cloud describes a scenario in which an Organization is operating both Public and Private Cloud, In Simple words the Public and Private Cloud are mingled with each other

Now Let’s know what are the 3 main types of Cloud Computing IAAS --- Infra Structure as a service SAAS --- Software as a service PAAS --- Platform as a service In this we will see on IAAS in upcoming blogs I will explain briefly on SAAS and PAAS Infrastructure as a Service - Basic layer of cloud computing, In simple words an organization/ Company Rent their servers for compute and storage in the cloud

So the users can run any OS or an application on that rented servers without any cost of those servers IAAS is mainly for Compute, Storage, Load balancing and Network

Advantages: • It Gives Customers to access their servers in any geographic locations close to them • Automatically scales Up and down depending on the Traffics • No Need of Managing any physical server also we can avoid the maintenance of the servers • IAAS is disaster recovery too • The Implementation can be in Public, Private and Hybrid it can be accessed using the API Keys

Facts: API Keys are Like a Secret Alpha Numeric Characters (abc12346)

• The IAAS can be used in data analysis, Test and development

IAAS is used in AWS EC2 mainly, Azure and GCP Few IAAS Providers for your reference 1.AWS – Netflix, LinkedIn and ESPN 2.GCP – Intel, Version and SAP 3.Azure – eBay, BMW 4.Alibaba Cloud – Air Asia, Ford 5.IBM Cloud – American Airlines 6.Digital Ocean - Accenture

In our Last Blog we saw about IAAS now we will see a brief description about SAAS and PAAS • SAAS--- Software as a service it is a kind of delivering the applications, instead of installing a software you can simply connect it via the internet, the applications on SAAS runs on the SAAS provided servers, the lender will manage the application including the performance, availability and security • It is also called as a web and on-demand based software

Features of SAAS • Low-cost • Availability • Security • Better Performance Industries Using SAAS • AWS • Microsoft • CISCO • GitHub • Slack • Oracle, etc

PAAS-- Platform as a service In simple words PAAS Really means renting platform for developers to build an application in this case the developers will rely on Cloud Providers, this platform usually simplifies the development of Web Application from the developer’s point of view Features of PAAS • Low Price • High-speed • Easy to use • Industries Providing PAAS • Amazon Web Services • IBM • Microsoft • Google

So Finally. Why Choose AWS?? • Security • Flexibility • Deployment • Performance • Pricing

Note: Also. Please be careful while using the services kindly turn off all the services post using it or else you might end up with heavy bills
