Let’s Dig Down in AWS…!!

EC2 by AWS

As we know that there are many services which are offered by AWS , lets pick few and try to understand their usage and utility it has for us:

AWS EC 2 (Virtual Servers on Cloud)

  • EC2 stands for Elastic Compute Cloud
  • It is one of the most famous offerings by AWS
  • It is a IaaS platform
  • It is basically renting of VMs
  • Storing data on Virtual Drives (EBS , ELB) and Distributing load across machines
  • Scaling of service using an auto-scaling group (ASG)

There are wide variety of Amazon EC2 Instance types comprise varying combinations of CPU, memory, storage, and networking capacity that gives you the flexibility to choose the appropriate mix of resources for your applications.

Each instance type includes one or more instance sizes, allow you to scale your resources either up or down and in or out to the requirements of your target workload.

Types of EC2 Instance Types

  • General Purpose
  • Memory Optimized
  • Compute Optimized
  • Accelerated Computing
  • Storage Optimized

Let’s understand Microsoft Azure?

Azure from the family of Microsoft

Azure the cloud platform introduced by the software giants Microsoft. Azure the latest cloud platform among the others famous cloud platforms such as AWS (Amazon Web Services) and Google Cloud. Azure was launched a decade ago in the market.

Azure provides a wide variety of services to its users that can be used without purchasing and provisioning your own hardware. Azure provides solution and rapid development to its resources that may not be possible in an on-premises environment. To people who are new to understand the word on-premise meaning services available on your desktop not on the cloud.

Azure provides a variety of services in its kitty such as compute, storage, network, and application services that allow users to focus on building great solutions without the need to worry about how the physical infrastructure is assembled.


Rulers of Cloud


What are the building blocks of Azure?

Azure App Service and Web Apps that consist of Web Apps, Logic Apps, Mobile Apps, API Apps, and Function Apps.

Azure Services includes many services in its cloud computing platform such as:

Compute services – This includes the Azure Virtual Machines—both Linux and Windows, Cloud Services, App Services (Web Apps, Mobile Apps, Logic Apps, API Apps, and Function Apps), RemoteApp, Service Fabric, and the Azure Container Service.

Data services – This includes Microsoft Azure Storage (comprised of the Blob, Queue, Table, and Azure Files services), Azure SQL Database, DocumentDB, StorSimple, and the Redis Cache.

Application services – This includes services that you can use to help build and operate your applications, such as Azure Active Directory (Azure AD), Service Bus for connecting distributed systems, HDInsight for processing big data, Azure Scheduler, and Azure Media Services.

Network services – This includes Virtual Networks, ExpressRoute, Azure DNS, Azure Traffic Manager, and the Azure Content Delivery Network.

These are the following cloud offerings classified in three categories :

  • SaaS
  • PaaS
  • IaaS

For more information on the above cloud offerings, please check our earlier blog “Similarities between Cloud Computing and Pizza“.

We will keep adding more information to our blogs time to time in the meantime if you need to contact us for any business services, please contact below or click here to check our website for any services.

Similarities between Cloud Computing and Pizza

Today, we all talk about cloud, but some of us are unaware of it, some say yes it is something to deal with the cloud which is floating above us which is not true as here cloud has been used as a metaphor.

Though you will get a lot of information over the cloud (internet,) if you just punch in these words “CLOUD Computing” on the search engine but to a non-technical or a walker/passerby it will be difficult to explain. So here I will explain it in a simple and crispy manner that if you are going for an interview too, you would be able to explain it even to the people travelling with you on the way..

What is Cloud?

Cloud is something that is over the net and is simply available by googling. You just need to grab it from the web i.e. cloud (internet).

What is Cloud Computing?

The use of remote servers over the internet to store, manage, process (google drive, dropbox, etc.) data rather than on a local server or personal computer.

Service Models by Cloud Computing

IaaS > SaaS> PaaS

IaaS>PaaS>SaaS

IaaS – When cooking Pizza at home and buying the pizza stuff like base , toppings, cheese, tomato sauce from the market.

PaaS – Home delivery or Pick up of pizza from the store.

SaaS – Eating outside at the store of Domino’s/Pizza hut.

Service Models by Cloud Computing

IaaS < Infrastructure as a service (IaaS) is a form of cloud computing that provides virtualized computing resources over the internet

PaaS < Platform as a service (PaaS) is a cloud computing model in which a third-party provider delivers hardware and software tools — usually those needed for application development to users over the internet. 

SaaS < Software as a service (SaaS) is a software distribution model in which a third-party provider hosts applications and makes them available to customers over the Internet such as Google Drive, DropBox, iCloud

This is the simplest understanding of the Cloud and its models ..!! I hope you had the understanding of these terms in the simplest ways..!!
