"Secure, Scalable, and Smart: Exploring the Cloud Computing Frontier"
What is cloud computing?
Cloud computing is the delivery of on-demand computing services over the internet on a pay as you go basis.
->The term cloud refers to a network or the internet.
->Entire building convert as a data center.
Features of cloud computing
-> Resource pooling : all the resources are stored at one place
->On demand self-service : any time you can access any thing
-> easy maintenance
->large Network access
-> Availability
->Economical
->Security
->Pay As you go
->Measured service
Why cloud computing?
On Premises -> Higher pay , less Scalability
->Allot huge space fir server
->Appoint a team for hardware and software maintenance
->Poor data security
->Less chance of data running
->lack of flexibility
->No automatic updates
->Takes longer implementation time.
Cloud computing
-> Pay for what you use scale downs pay less
Scale ups pay more , scale downs pay less
-> No server required for Hardware and software maintenance
-> Better data security
->Disaster recovery
-> Higher Flexibility
->Automatic Software updates
->Data can be accessed and shared anywhere over the internet
->Read implementation.
What is infrastructure?(resources)
In cloud computing, "infrastructure" refers to the foundational components and resources that support the delivery of various computing services over the internet. These components are typically virtuallized and managed by cloud service providers, allowing users to access and utilize them on-demand without needing to invest in physical hardware.
->Servers
-> Networking
-> Database
-> Storage
What is IP address?
An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. IP addresses serve two main purposes: identifying the host or network interface, and providing the location of the host in the network, which allows devices to communicate with each other over the internet or within a private network.
IP address can be assigned in two ways:
-> Statically
->Dynamically
We will have
IPv4 Address
Sub net Mask
Default Gateway : This is connected to the main Router it will have same IP address for everyone.
How many ways to get infrastructure (resource)
->Physically
->Virtually (3rd party software)
->Cloud
On premises(physically)
"on-premises" (often abbreviated as "on-perm") refers to IT infrastructure and services that are physically located and managed within an organization's own facilities, such as a data center or server room
Virtually
virtually" refers to the use of virtualization technology to create and manage resources such as servers, storage, and networks in a software-defined environment rather than using physical hardware exclusively. Virtualization allows multiple virtual resources to run on a single physical machine, optimizing resource usage, improving flexibility, and reducing costs.
Cloud computing
Cloud computing is a technology that allows individuals and organizations to access computing resources, such as servers, storage, databases, networking, software, and more, over the internet. Instead of owning and maintaining physical hardware, users can rent these resources from cloud service providers on a pay-as-you-go basis, which offers flexibility, scalability, and cost savings.
What is Cloud Computing ? Definition, Benefits,Types, and Trends-Spice works
Public cloud (shareable Storage)
The cloud infrastructure is made available to the general public over the internet and it is owned by a cloud provider.
Ex : AWS ,Azure, IBM ,Blue cloud , Sun cloud
Private Cloud (Organization , Security)
The cloud infrastructure is exclusively operation by a single organization . It can be managed by the organization or a third party and may exist on-premise or off-premise.
Ex: AWS, VMware
Hybrid Cloud
It consists the functionalities of both private and public cloud
Service model
IASS (Infrastructure as a service)
If your business needs a virtual machine , opt for infrastructure as a service (EC2 as IASS)
->Services are available on pay -for-what-you-use model
->IASS providers include AWS, Azure, Google computer engine.
-> Users :IT administrators.
PASS (Platform as a Service)
If your company requires platform for building software products , pick platform as a service.
-> PASS provides cloud platforms and runtime environment for developing, testing and managing applications.
-> Users:Software Developer
SASS (Software as a Service)
If your business doesn't want to maintain any equipment , then choose Software as a service.
->In SASS cloud providers host and manage the software applications on a pay as you go pricing model.
->All software and hardware are provided and managed by a vendor so you don’t have to maintain anything.
->users : End customers
(G mail,Drive, excel sheets)
Platforms for cloud computing
->AWS
->Microsoft Azure
->Google Cloud platform
->IBM
What is data center?
Data center is where you can store all the servers and all the configurations of the server in data center that is called data center.
What is configuration ?
The Specific hardware and software details of the devices, servers , and the capability and the capacity, exactly what the system is made of.
What is virtualization?
Where we can create the operating system , hypervisors , virtual machines , virtually but not physically
What is hypervisors?
Where you run multiple virtual machine on a single physically machine or server is called hypervisors.
