1. what is service model?
2, What is deployment model?
3. bifurcation of service model in cloud
4. bifurcation of deployment model in cloud
5. what is the role of service and deployment model?
1.A service model is a strategic framework that defines how an organization designs, delivers, and manages its services to meet customer or business needs.
2.A deployment model defines where a system's infrastructure lives, who owns and manages it, and how users access it.
3. The cloud service model is divided into three primary layers: IAAS(infrastructure as a Service), PAAS(Platform as a Service), SAAS(Software as a Service).
4.The cloud service is divided into four layers: Public cloud, private cloud, hybrid cloud, multi cloud.
5.Service and deployment models define how cloud computing infrastructure is structured, shared, and delivered to users.
Role of service models: It define what level of IT resource is delivered and how management responsibilities are split between you and the provider.
Role of deployment models: It determine where your infrastructure lives, who owns and manages it, and how it accessed.

2.What are the cloud deployment models?
3.What are public and private clouds?
4.What are hybrid cloud and multi-cloud environments?
5.Explain any two cloud service models.
1. what are the cloud service models?
i. Infra structure as a service
ii. platform as a service
iii Software as a service
2. waht are the cloud deployment models?
i. public cloud
ii private cloud
iii hybrid cloud
iv. Multi cloud
3. what are public and private cloud?
public cloud=infrastructure owned & operated by third party provider, shared among many different organizations/users over the internet. Eg: AWS, microsoft azure, Google cloud
private cloud= infrastructure dedicated to one single organization, not shared with any one else. Eg: VMware, Openstack
4. what are hybrid cloud and multiple cloud environment?
Hybrid cloud = public + private cloud connected together as one unified system. keeps sensitive data's in private cloud and non sensitive data's in public cloud
5. explain any two cloud service models?
IaaS: Infra structure as a Service. Cloud provider gives you raw infrastructure - virtual computing resources over the internet. you rent hardware , you manage everything installed on top
eg: EC2(virtual service), S3(storage), VPC(network)
PaaS: Platform as a service. Cloud provider delivers a complete deployment & deployment platform. you only bring your code & data-provider handles the infrastructure, OS, runtime and maintenance.
eg: Elastic Beanstalk, Lambda, RDS(managed data base)

1.what is AWS global infrastructure?
2.what is regions?
3.what is availability zone?
4.how many minimum and maximum AZ in one regions?
5.why are regions connected through cable?
1. What is AWS global infrastructure?
AWS global infrastructure = the physical & operational backbone that makes all AWS services run reliably, fast and securely world wide.
Its built in 3 layers: Regions --> Availability Zones --> Edge locations
2. what is regions?
The Main Building block and a geographical area with 1+ data centres. it is completely indepent from other regions. it has isolated power, network, security.
key rule: Data doesn't leave gthe region unless you choose.
eg: region name is Singapore and it code is ap-southeast-1
3. what is availability zone?
Physically separate data centres kilometers apart. each has its own independent power, cooling system, networks. DC is connected by low-latency, high speed, private links. If one AZs fails other keep running 99.99+ availability.
4. How many min and max AZ in one region?
min 3 AZs and Max 6AZs
5. Why regions are connected through cable?
They are only practical way to move massive amounts of data fast , reliably and affordably between regions. Satellites can't match them.
key reasons: unmatched and low latency, disaster recovery, reliability and redundancy, security.
