Introduction to Cloud Computing (IaaS, PaaS, SaaS)

Pascual Vila

Cloud Instructor.

Cloud computing is the delivery of computing services over the internet. Cloud service models define what you manage versus what the provider manages.

IaaS (Infrastructure as a Service)

IaaS provides virtualized computing resources. You manage the operating system, applications, and data, while the provider manages infrastructure. AWS examples: EC2, EBS, VPC.

PaaS (Platform as a Service)

PaaS provides a platform for developing and deploying applications. You manage applications and data, while the provider manages infrastructure and runtime. AWS examples: Elastic Beanstalk, Lambda, ECS.

SaaS (Software as a Service)

SaaS delivers software applications over the internet. You only manage user access and data, while the provider manages everything else. Examples: Gmail, Salesforce, Office 365.

Cloud Computing Glossary

Cloud Computing: The delivery of computing services over the internet. Instead of owning physical servers, you access computing resources on-demand from a cloud provider.
IaaS (Infrastructure as a Service): A cloud service model where you manage the operating system, applications, and data, while the provider manages infrastructure (servers, storage, networking). Examples: EC2, EBS, VPC.
PaaS (Platform as a Service): A cloud service model where you manage applications and data, while the provider manages infrastructure and runtime environment. Examples: Elastic Beanstalk, Lambda, ECS.
SaaS (Software as a Service): A cloud service model where you only manage user access and data, while the provider manages everything else. Examples: Gmail, Salesforce, Office 365.
On-Demand: Accessing computing resources when needed, without long-term commitments. You pay only for what you use.
Scalability: The ability to scale computing resources up or down based on demand. Cloud computing provides automatic or manual scaling capabilities.
